Description

本発明は、物品の内角部分及び外角部分の角度を測定する角度測定器に関する。   The present invention relates to an angle measuring device for measuring the angle of an inner corner portion and an outer corner portion of an article.

本発明者は先に下記特許文献1のノギス型デジタル角度・距離計を提案し、この装置によって工業用部品等の物品の外角部分の傾斜角度の測定をし、その角度をデジタル数字で表示できるものとした。   The present inventor previously proposed a caliper type digital angle / distance meter disclosed in Patent Document 1 below, and with this device, the inclination angle of an outer angle portion of an article such as an industrial part can be measured, and the angle can be displayed as a digital number. It was supposed to be.

しかしながら、この装置では、測定すべき物品を本尺のジョウとバーニヤのジョウとの間に配して、その物品を挟んで向かい合った回動測定面で測定するため本尺のジョウとバーニヤのジョウとの間に入る大きさの物品の外角部分については測定することはできるが、物品の内角部分については、回動測定面の間に挟むことができないために測定することが不可能であった。
又、その測定可能な外角の角度も本尺面に対して、一方の外角面と他方の外角面の角度を別々に測定してから両外角面間の角度が算出されるため、誤差も合算されて誤差の値も大きくなってしまうため測定精度を大きく高めることが困難であった。
However, in this apparatus, the article to be measured is placed between the main scale jaw and the vernier jaw, and the main scale jaw and the vernier jaw are measured in order to measure on the rotational measurement surfaces facing each other across the article. It is possible to measure the outer corner of an article of a size between the two, but the inner corner of the article cannot be measured because it cannot be sandwiched between rotation measurement surfaces. .
Also, the measurable outside angle is also measured with respect to the main scale surface because the angle between one outside angle surface and the other outside angle surface is calculated separately, and the error is also added. As a result, the error value also increases, and it is difficult to greatly increase the measurement accuracy.

そして、同時に両回動測定面の角度を円弧に添った磁気目盛面から磁気センサーで感知し、その感知したデータは電子演算部で演算処理されその演算結果が液晶表示部でデジタル数値として表示することが可能となる。
その測定精度は、内角及び外角のいずれでも前記円弧が大きければ大きいほど目盛り幅を大きくすることが可能となり、より正確な精度でその角度を測定すること可能となる。
特に、本発明では、前記ノギス型デジタル角度・距離計の如く、測定対象物の一方の面を必ず本尺のスライド面に当接させて該スライド面を基準に回動測定面の角度を読み、更に両方に数値を合算して外角の角度を2段階で算出するのではなく、測定対象物の測定面に対して押し当てられる回動測定面の角度が各磁気目盛面から検出した2つの値から直接角度が算出されるため、誤差が少なく、より正確な精度の内角と外角の角度の測定結果が得られる。
In the invention of claim 1, the rotation measuring surface of the angle measuring element freely rotates over the entire circumference avoiding the rotation support body outside the tip end portion and both side surface portions of the rotation support body, When measuring the outer angle part, the measurement part of the measurement object is sandwiched between both rotation measurement surfaces, and both rotation measurement surfaces are pressed against both measurement surfaces of the outer angle at the same time. The rotation measurement surfaces on both sides are in intimate contact with the outer angle surfaces on both sides, and when measuring the inner angle part, insert the angle measuring elements on both sides between the inner angle surfaces of the measurement part. By simultaneously pressing both measurement surfaces at both inner angles of the measurement object, the rotational measurement surfaces on both sides are brought into close contact with both inner angle surfaces of the measurement object.
At the same time, the angle of both rotation measuring surfaces is sensed by a magnetic sensor from the magnetic scale surface along the arc, and the sensed data is computed by the electronic computation unit and the computation result is displayed as a digital numerical value on the liquid crystal display unit. It becomes possible.
As for the measurement accuracy, the larger the arc is, the larger the scale width is, and the more accurate the angle can be measured.
In particular, in the present invention, like the caliper type digital angle / distance meter, one surface of the measurement object is always brought into contact with the main slide surface, and the angle of the rotation measurement surface is read with reference to the slide surface. In addition, the numerical value is not added to both, and the angle of the outer angle is not calculated in two steps, but the angle of the rotational measurement surface pressed against the measurement surface of the measurement object is detected from each magnetic scale surface. Since the angle is directly calculated from the value, there are few errors, and more accurate measurement results of the inner and outer angles can be obtained.

請求項2の発明においては、上記請求項1の発明と同様に、角度測定子の回動測定面が回動支持体の先端部及び両側面部よりも外側の該回動支持体を避けた全周に亘って自由に回動し、外角部分を測定する場合には、測定対象物の測定部分を両回動測定面の内部に挟んで、両回動測定面を外角の両測定面に同時に押し当てることで、両測定対象物の両側の外角面に両側の回動測定面が密接され、又、内角部分を測定する場合には、測定部分の両内角面の間に両側の角度測定子を差し込んで、両回動測定面を測定対象物の両内角の両測定面に同時に押し当てることで、測定対象物の両内角面に両側の回動測定面が密接される。
そして、両測定対象物の両測定面に同時に両側の角度測定子の回動測定面が密接されると、角度測定子の固着した枢支軸の回動角度変化で変化する光を両側の光センサーで光学的に感知し、その感知した両側の光センサーのデータは電子演算部で演算処理されその演算結果が液晶表示部で、測定対象物の内角又は外角を正確なデジタルの数値として表示することが可能となる。
In the second aspect of the invention, as in the first aspect of the invention, the rotation measuring surface of the angle measuring element avoids the rotation support body outside the front end portion and both side surface portions of the rotation support body. When measuring the outer angle part by freely rotating over the circumference, the measurement part of the object to be measured is sandwiched between the two measurement surfaces, and both measurement surfaces are simultaneously placed on both measurement surfaces of the outer angle. By pressing, the rotating measurement surfaces on both sides are brought into close contact with the outer angle surfaces on both sides of both objects to be measured, and when measuring the inner angle portion, the angle measuring elements on both sides are measured between the inner angle surfaces of the measurement portion. , And both rotational measurement surfaces are pressed against both measurement surfaces at both internal angles of the measurement object, whereby the rotational measurement surfaces on both sides are brought into close contact with both internal corner surfaces of the measurement object.
When the rotation measurement surfaces of the angle measuring elements on both sides are simultaneously brought into close contact with both measurement surfaces of both objects to be measured, the light that changes due to the change in the rotation angle of the pivot shaft to which the angle measurement element is fixed is changed to the light on both sides. Optically sensed by the sensor, the data of the sensed photosensors on both sides is processed by the electronic calculation unit, and the calculation result is displayed on the liquid crystal display unit, and the internal or external angle of the measurement object is displayed as an accurate digital value. It becomes possible.

請求項3の発明においては、重ねられた回転偏光板と回転偏光板とが相対的に回動することによって回転偏光板及び回転偏光板に対して照射された光の透過量が変化し、その回転偏光板及び回転偏光板とを透過した光を光センサーで受光してその光の量を数値化し、測定対象物の内角及び外角をより正確に測定し、液晶表示部にデジタル数値で表示することが可能となる。   In the invention of claim 3, the amount of light transmitted to the rotating polarizing plate and the rotating polarizing plate is changed by the relative rotation of the stacked rotating polarizing plate and the rotating polarizing plate. The light transmitted through the rotating polarizing plate and the rotating polarizing plate is received by the optical sensor, the amount of the light is digitized, the inner angle and the outer angle of the measurement object are more accurately measured, and the digital numerical value is displayed on the liquid crystal display unit. It becomes possible.

請求項4の発明においては、前記両角度測定子のローター部を、該両角度測定子の板面を同一平面に配することで対向した両角度測定子の回動測定面が測定対象物の内角及び外角の測定面に確実に密接し、測定対象物の平面的な薄い部分の内角及び外角を正確に測定することが可能となる。   According to a fourth aspect of the present invention, the rotation measuring surfaces of the two angle measuring elements facing each other by arranging the rotor portions of the both angle measuring elements on the same plane are the objects to be measured. It becomes possible to accurately measure the inner angle and the outer angle of the planar thin portion of the measuring object while being in close contact with the measurement surfaces of the inner angle and the outer angle.

請求項5の発明においては、前記両角度測定子のローター部の板面の一部が接近して相互に重なって、その部分において回動測定面を交差させ、その回動測定面の交差部分の間に測定対象物を挟むようにして両外角面を同時に押し当て密接せることとで極めて小さな測定対象物でもその外角の測定が可能となる。
また内角では、板面の一部を相互に重なるようにして小さな測定対象物の内角の測定が可能となり、この場合、両回動測定面の端部同士が接触状態となると、その端部を頂点として測定対象物の両内角面を最小範囲まで同時に密接させることができるので、極めて小さな測定対象物の内角の測定が可能となる。
なお、両回動測定面の端部同士が離れた状態であっても、その離れた端部間の距離よりも小さい測定対象物ではその両内角面に両回動測定面を同時に密接させることができないので、その場合には内角の測定できなくなるが、回動測定面が測定対象物の両内角面に同時に密接可能な限り、どのような大きさの測定対象物でもその内角の測定が可能となる。
In a fifth aspect of the present invention, a part of the plate surface of the rotor part of the angle measuring element approaches and overlaps each other, and the rotational measurement surface intersects at that part, and the intersecting part of the rotational measurement surface The outer angle can be measured even with a very small measurement object by simultaneously pressing and closely contacting both outer angle surfaces with the measurement object sandwiched between them.
In addition, at the inner angle, it becomes possible to measure the inner angle of a small measurement object so that a part of the plate surface overlaps each other. In this case, when the ends of both rotation measurement surfaces are in contact with each other, Since both internal angle surfaces of the measurement object can be brought into close contact with each other to the minimum range as apexes, it is possible to measure an extremely small internal angle of the measurement object.
In addition, even if the ends of the both rotation measurement surfaces are separated from each other, in the case of a measurement object smaller than the distance between the separated ends, the both rotation measurement surfaces should be brought into close contact with both inner corner surfaces at the same time. In this case, the internal angle cannot be measured. However, as long as the rotational measurement surface can be in close contact with both internal angle surfaces of the measurement object, it is possible to measure the internal angle of any measurement object. It becomes.

請求項6の発明においては、前記角度測定子をどちらかに回動させると、前記回動支持体に設けた測定基準位置決めピンがローター部に設けたピン逃がし面を通過しピン突当り部に当たって停止する。
その際、前記角度測定子のローター部が前記回動支持体の先端より外側に180度範囲に回動して前記回動測定面の向かい合わせ側と背中合わせ側とがどちらかに回動させても平行となって停止し、このことにより内角及び外角の全角度が確実に測定可能となり、且つ測定基準位置決めピンがピン突当り部より先には回動しないので、その限られた目盛りの範囲の読み取りによって効率良く測定が行える。
そして、回動が停止して両回動測定面が平行となったときが測定の基準位置となって、新たに基準位置を定めずにそのままで効率良く測定することが可能となる。
According to a sixth aspect of the present invention, when the angle measuring element is rotated in either direction, the measurement reference positioning pin provided in the rotating support member passes through the pin relief surface provided in the rotor part and stops at the pin contact part. To do.
At that time, the rotor part of the angle measuring element is rotated in the range of 180 degrees outward from the tip of the rotation support member, and the opposite side and the back-to-back side of the rotation measurement surface are rotated in either direction. This also makes it possible to reliably measure all the inner and outer angles, and the measurement reference positioning pin does not rotate beyond the pin abutting portion. Measurement can be performed efficiently by reading.
And when rotation stops and both rotation measurement surfaces become parallel, it becomes a measurement reference position, and it becomes possible to measure efficiently as it is without setting a new reference position.

請求項7の発明においては、両回動支持体間の間隔を拡縮させることで、コーナー部分が変形している測定対象物であってもそのコーナー部分を避けて角度を正確に測定することが可能となる。   In the invention of claim 7, the angle between the two rotation supports can be expanded and reduced so that the angle can be accurately measured while avoiding the corner portion even if the corner portion is deformed. It becomes possible.

請求項8の発明においては、前記回動支持体の先端部を高い位置まで調節することで、内角の測定では前記回動支持体の先端部に設けた角度測定子の回動測定面が内角の深い位置まで届くようになり、又、外角の測定では前記回動支持体の先端部に設けた角度測定子の回動測定面の間に外角部分の先端部が深い位置まで差し込めるようになる。
この結果、測定対象物の測定部分が深い位置にあっても測定が可能となる。
In the invention of claim 8, by adjusting the tip end portion of the rotation support member to a high position, the rotation measuring surface of the angle measuring element provided at the tip end portion of the rotation support member is set to the inner angle for measuring the inner angle. In the measurement of the outer angle, the outer end of the outer angle portion can be inserted to the deep position between the rotation measuring surfaces of the angle measuring element provided at the end of the rotating support. Become.
As a result, measurement is possible even when the measurement portion of the measurement object is deep.

請求項9の発明においては、前記演算表示部と基台とが一体となるので保管や持ち運びが容易となる。
そして、全角度測定器全体を片手で持って移動しつつ、そのまま前記角度測定子を測定対象物に押し当ることで、片手だけででも角度を測定することが可能となる。
According to the ninth aspect of the present invention, since the calculation display unit and the base are integrated, it is easy to store and carry.
Then, while moving the entire angle measuring device with one hand, the angle measuring element is pressed against the object to be measured as it is, so that the angle can be measured with only one hand.

尚、該図1では、前記基台1は長板状の基台1aを用いた態様を示しているが、該基台1は一対の対向した回動支持体2、3を平行状態に固定できれば良いので、棒状や筒状等であっても良い。
In the embodiment using the magnetic sensor of the present invention, as shown in FIG. 1, a pair of rotating supports 2, 3 stands upright in parallel on a base 1, and the ends of the rotating supports 2, 3 are bifurcated. The support portions 2a, 2a, 3a, 3a are formed on the support portions 2a, 3a, and as shown in FIG. 5 are provided.
In FIG. 1, the base 1 has a long plate-like base 1a. However, the base 1 fixes a pair of opposed rotating supports 2 and 3 in a parallel state. As long as it is possible, it may be a rod shape or a cylindrical shape.

そして、図4に示すように、前記回動支持体2、3の二股の支持部2a、3aの二股間に、
前記枢支軸4a、5aを介して中心部で枢支された優弧半円板状のローター部6a、7aと、該ローター部6a、7aの劣優側に設けた直径方向と平行な回動測定面8、9と、該ローター部6a、7aの優弧の円周に沿って設けた磁気目盛面10、11とを備えた角度測定子6、7を挟み、前記枢支部4、5に夫々枢着する。
その際、前記回動測定面8、9が回動支持体2、3の先端部及び両側面部よりも外側を、向かい合わせ平行状態(図4中に実線で示す)から背中合わせ平行状態(図4中に一点鎖線で示す)にまで前記回動支持体2、3を除く全周に亘って自由に回動できるように前記枢支軸4a、5aを介して角度測定子6、7をローター部6a、7aの円形中心部で枢着する。
And, as shown in FIG. 4, the bifurcated support portions 2a, 3a of the rotating supports 2, 3
A semi-circular disc-shaped rotor portion 6a, 7a pivotally supported at the center via the pivot shafts 4a, 5a, and a diametrically parallel rotation provided on the inferior side of the rotor portions 6a, 7a. The angle measuring elements 6 and 7 including the dynamic measuring surfaces 8 and 9 and the magnetic graduation surfaces 10 and 11 provided along the circumference of the dominant arc of the rotor parts 6a and 7a are sandwiched between the pivot supporting parts 4 and 5 To each other.
At that time, the rotation measuring surfaces 8 and 9 are arranged so that the outer sides of the distal end portions and both side surface portions of the rotation supports 2 and 3 are opposed to each other in a parallel state (shown by a solid line in FIG. 4). The angle measuring elements 6 and 7 through the pivot shafts 4a and 5a so that they can freely rotate over the entire circumference excluding the rotating supports 2 and 3). It is pivotally attached at the circular center of 6a and 7a.

前記回動測定面8、9はローター部6a、7aの劣優側の各端部8a、9a、8b、9bまでを正確に直線状とする。例えば、図1に示すように、前記回動測定面8、9面に直線精度の高い丸い鋼線を用いて前記回動測定面8、9に形成した溝内に外鋼線の外円周面を露出させて埋め込んだ態様が可能である。この態様では、測定対象物の内角面及び外角面に対して鋼線の円周が直線状に当接可能となる。この態様では前記回動測定面8、9が測定対象物の内角面及び外角面の広範に接触しないため汚れによる表面のゴミや凹凸の影響が少なくより正確に測定することができる。
尚、図1では支持部2a、3aを二股としているが、本発明では支持部2a、3aで両角度測定子6、7が向かい合うように支持できれば良いので二股に限定するものではない。
The rotation measuring surfaces 8 and 9 are accurately linearly arranged up to the end portions 8a, 9a, 8b and 9b on the inferior side of the rotor portions 6a and 7a. For example, as shown in FIG. 1, the outer circumference of the outer steel wire is placed in a groove formed on the rotation measurement surfaces 8 and 9 using a round steel wire with high linear accuracy on the rotation measurement surfaces 8 and 9. An embodiment in which the surface is exposed and embedded is possible. In this aspect, the circumference of the steel wire can come into linear contact with the inner and outer corner surfaces of the measurement object. In this aspect, since the rotation measuring surfaces 8 and 9 do not contact the inner and outer surfaces of the measurement object extensively, the surface can be measured more accurately with less influence of dirt and irregularities on the surface due to dirt.
In FIG. 1, the support portions 2a and 3a are bifurcated. However, in the present invention, the support portions 2a and 3a only need to be supported so that the angle measuring elements 6 and 7 face each other, and therefore, the support portions 2a and 3a are not limited to bifurcation.

そして、前記角度測定子6、7外周の磁気目盛面10、11には帯の長さ方向に角度の大きさの目盛りを磁気で記憶させた磁気目盛帯10a、11aを張設する。
そのため角度測定子6、7の外周面に形成される磁気目盛面10、11の幅を、例えば3mm程度とすれば、該磁気目盛面10、11に約2mm幅の磁気目盛帯10a、11aを張設することができる。
Magnetic graduation bands 10a and 11a in which a graduation having an angle magnitude is stored magnetically are stretched on the magnetic graduation surfaces 10 and 11 on the outer circumferences of the angle measuring elements 6 and 7.
Therefore, if the width of the magnetic graduation surfaces 10 and 11 formed on the outer peripheral surfaces of the angle measuring elements 6 and 7 is about 3 mm, for example, the magnetic graduation bands 10a and 11a having a width of about 2 mm are provided on the magnetic graduation surfaces 10 and 11, respectively. Can be tensioned.

又、前記両回動支持体2、3に、前記角度測定子6、7の回動変化の量を磁気目盛帯10a、11aからその磁気を感知する磁気センサー12a、13aを前記磁気目盛面10、11の磁気目盛帯10a、11aに接するように臨ませて設ける。
該磁気センサー12a、13aと前記磁気目盛面10、11とで角度の変化に対応した数値に変化が得られる角度検出部12、13を形成し、この角度検出部12、13で前記角度測定子6、7の回動変化で前記磁気目盛面10、11が回動したとき前記磁気目盛面10、11に記憶させた数値を磁気センサー12a、13aで前記回動測定面8、9の角度として読み取る。
Further, magnetic sensors 12a and 13a for detecting the magnetism from the magnetic graduation bands 10a and 11a on the magnetic graduation surfaces 10 and 11a are provided on the magnetic graduation surface 10 on both the rotational supports 2 and 3, respectively. , 11 so as to face the magnetic graduation bands 10a, 11a.
The magnetic sensors 12a and 13a and the magnetic graduation surfaces 10 and 11 form angle detectors 12 and 13 that can change the numerical value corresponding to the change of the angle. The angle detectors 12 and 13 form the angle measurer. When the magnetic graduation surfaces 10 and 11 are rotated by the rotational changes of 6 and 7, the values stored in the magnetic graduation surfaces 10 and 11 are used as the angles of the rotational measurement surfaces 8 and 9 by the magnetic sensors 12a and 13a. read.

前記両回動支持体2、3への前記磁気センサー12a、13aの装着は、図3に示すように、前記両角度測定子6、7のローター部6a、7aの外周面に臨む前記両回動支持体2、3の二股の分岐部に磁気センサー取付け部2b、3bの空間を刳り抜いて設ければ、前記磁気センサー12a、13aを前記角度測定子6、7の磁気目盛面10、11に接するようにセンシング部分を臨ませてネジで位置決めして固定することができる。   As shown in FIG. 3, the magnetic sensors 12a and 13a are mounted on the rotating support bodies 2 and 3, as shown in FIG. 3, with the two rotations facing the outer peripheral surfaces of the rotor portions 6a and 7a of the angle measuring elements 6 and 7. If the space between the magnetic sensor mounting portions 2b and 3b is cut out at the bifurcated branch portions of the moving supports 2 and 3, the magnetic sensors 12a and 13a are connected to the magnetic scale surfaces 10 and 11 of the angle measuring elements 6 and 7, respectively. The sensing part can be faced so as to be in contact with the screw, and can be positioned and fixed with screws.

図1では、該角度測定子6、7のローター部6a、7aは円盤状を成し、外周面に磁気目盛帯10a、11aを設けた態様を示したが、磁気目盛帯10a、11aは角度測定子6、7の円弧に添ったローター部6a、7aの板面に設けることも可能であり、その場合、前記磁気センサー12a、13aの位置は、二股中央ではなく、一方の二股部分に前記磁気目盛帯10a、11aにセンシング部分を臨ませて接するように磁気センサー12a、13aを設ける。   In FIG. 1, the rotor portions 6 a and 7 a of the angle measuring elements 6 and 7 have a disk shape and the magnetic scale bands 10 a and 11 a are provided on the outer peripheral surface, but the magnetic scale bands 10 a and 11 a are angled. It is also possible to provide on the plate surface of the rotor parts 6a, 7a along the arcs of the measuring elements 6, 7, and in this case, the position of the magnetic sensors 12a, 13a is not the center of the fork, but the one fork part. Magnetic sensors 12a and 13a are provided so that the sensing portions are in contact with the magnetic graduation bands 10a and 11a.

前記角度測定子6、7のローター部6a、7aの円弧の大きさは、精度の高さと関係し、円弧がければ大きいほど目盛り幅を大きくすることが可能となり、より正確な精度でその角度を測定すること可能となる。
又、ローター部6a、7aに円弧が小さいと前記回動測定面8、9が短くなり、測定対象物の内角面及び外角面に対して当接部分が少なくなり、このため測定精度は低下し、且つ円弧が小さいと目盛り幅が小さくなって精度が低下する場合がある。
The size of the arcs of the rotor portions 6a and 7a of the angle measuring elements 6 and 7 is related to the accuracy, and the larger the arc, the larger the scale width, and the more accurate the angle. Can be measured.
Further, if the arcs of the rotor portions 6a and 7a are small, the rotational measurement surfaces 8 and 9 are shortened, and the contact portions with respect to the inner and outer angle surfaces of the measurement object are reduced, and therefore the measurement accuracy is lowered. In addition, if the arc is small, the scale width may be reduced and accuracy may be reduced.

又、図1では、前記回動支持体2、3は、先端部2a、3aが二股に分かれた棒状のものを示しているが、前記回動支持体2、3は前記磁気センサー12a、13aを基台1から突出させた位置で支持するものなで、棒状に限定するものではなく、板状や筒状のものでも良い。   Further, in FIG. 1, the rotation supports 2 and 3 are rod-shaped with tip portions 2a and 3a divided into two branches, but the rotation supports 2 and 3 are the magnetic sensors 12a and 13a. Is not limited to a rod shape, but may be a plate shape or a cylindrical shape.

そして、図1に示すように、前記両磁気センサー12a、13aに夫々電線22を介して演算表示部23を接続する。
該演算表示部23には、前記磁気センサー12a、13aで感知された両回動測定面8、9の傾斜角度のデータからプログラムに従って、両傾斜角度の挟まれた内角又は外角を演算処理する電子演算部24とその演算結果をデジタル表示する液晶表示部25とを備える。
なお、図1では、前記各角度検出部12、13と演算表示部23とを電線22で接続した態様を示しているが、前記磁気センサー取付け部2b、3bに磁気センサー起動用の電池を装着し、前記各磁気センサー12a、13aで感知した目盛りのデータを演算処理する電子演算部24に無線送信手段を備えることで、電線22を使用しない装置とすることも可能である。
And as shown in FIG. 1, the calculation display part 23 is connected to the said both magnetic sensors 12a and 13a via the electric wire 22, respectively.
The computation display unit 23 is an electronic device that computes an inner angle or an outer angle between the two tilt angles according to a program from the tilt angle data of the both rotation measuring surfaces 8 and 9 detected by the magnetic sensors 12a and 13a. A calculation unit 24 and a liquid crystal display unit 25 that digitally displays the calculation result are provided.
FIG. 1 shows a state in which the angle detection units 12 and 13 and the calculation display unit 23 are connected by an electric wire 22, but a battery for starting a magnetic sensor is attached to the magnetic sensor mounting units 2b and 3b. In addition, it is possible to provide a device that does not use the electric wire 22 by providing a wireless transmission means in the electronic calculation unit 24 that performs calculation processing on the scale data sensed by the magnetic sensors 12a and 13a.

そして角度を測定する際は、図5及び図6に示すように、測定対象物Aの内角面A1、A2、又は測定対象物Bの外角面B1、B2に両側の回動測定面8、9を同時に押し当てて行う。
その際、前記両角度測定子6、7の回動測定面8、9は前記両回動支持体2、3の先端よりも外側を自由に回動するので、測定対象物に対して両側の回動測定面8、9を同時に押し当てると内角面に対しても又、外角面に対しても、測定対象物の内角x及び外角yの全角度の正確な測定が可能となる。
And when measuring an angle, as shown in FIG.5 and FIG.6, rotation measuring surface 8 and 9 of both sides is provided to inner angle surface A1, A2 of the measuring object A, or outer angle surface B1, B2 of the measuring object B, as shown in FIG. Press at the same time.
At that time, the rotation measuring surfaces 8 and 9 of the angle measuring elements 6 and 7 freely rotate outside the ends of the both rotation supporting bodies 2 and 3, so When the rotational measurement surfaces 8 and 9 are pressed at the same time, it is possible to accurately measure all of the inner angle x and the outer angle y of the object to be measured both on the inner angle surface and on the outer angle surface.

又、前記両角度測定子6、7は、図2に示すように、ローター部6a、7aの円形中心部で両側の平行且つ対向方向に直交した枢支軸4a、5aに枢支されることで両側の角度測定子6、7は同一平面上に配されるが、該角度測定子6、7のローター部6a、7aの形状は、図2の如く、板面を同一平面上に配する形態と、図10に示すように、板面を別の平面上に配すると共に板面の一部が相互に重なるように当接又は近接させた形態とが可能である。   Further, as shown in FIG. 2, the angle measuring elements 6 and 7 are pivotally supported on pivot shafts 4a and 5a that are parallel to both sides and orthogonal to the opposite direction at the circular center of the rotor portions 6a and 7a. The angle measuring elements 6 and 7 on both sides are arranged on the same plane. The rotor parts 6a and 7a of the angle measuring elements 6 and 7 are arranged on the same plane as shown in FIG. As shown in FIG. 10, it is possible to adopt a form and a form in which the plate surface is arranged on another plane and a part of the plate surface is in contact with or close to each other so as to overlap each other.

前記両角度測定子6、7のローター部6a、7aの板面を同一平面上に配した形態では、前記両回動支持体2、3の間隔は、少なくとも回動支持体2、3同士が接触しない間隔とし、図5に示すように、測定対象物Aの内角xを挟む両内角面A1、A2に前記回動測定面8、9が隙間なく当接でき、又、図6に示すように、測定対象物Bの外角yを挟む両内角面B1、B2に前記回動測定面8、9が隙間なく当接できる間隔とし、この態様によって、対向した両角度測定子6、7の回動測定面8、9が測定対象物の内角及び外角の測定面に確実に密接し、厚さの少ない測定対象物Bに対してもその内角及び外角を正確に測定することが可能となる。   In the form in which the plate surfaces of the rotor portions 6a and 7a of the angle measuring elements 6 and 7 are arranged on the same plane, the distance between the rotation support bodies 2 and 3 is at least between the rotation support bodies 2 and 3. As shown in FIG. 5, the rotation measurement surfaces 8 and 9 can be brought into contact with both inner corner surfaces A1 and A2 sandwiching the inner angle x of the measuring object A without any gap as shown in FIG. In addition, the rotation measurement surfaces 8 and 9 are spaced apart from each other with the inner angle surfaces B1 and B2 sandwiching the outer angle y of the measurement object B without any gaps. The dynamic measurement surfaces 8 and 9 are surely in close contact with the measurement surfaces of the inner and outer angles of the measurement object, and the inner and outer angles can be accurately measured even for the measurement object B having a small thickness.

又、前記ローター部6a、7aの板面の一部が相互に重なるように当接又は近接させた形態では、一方の角度測定子6は、図8に示すように、板面を1枚とし、他方の角度測定子7は、図9に示すように、前記一方の角度測定子6を1枚の板面を挟んだ間隔で2枚の板面を設けることができる。
そして、図10及び図11に示すように、前記ローター部6a、7aの擦違中板20の板面とその両側の擦違外板21a、21bの一部が接近して前記回動測定面8、9の両側の端部8a、9a、8b、9b寄りの一部が相互に重なって、その部分において回動測定面8、9を交差させ、その回動測定面8、9の交差部分を測定対象物Bの両外角面に当てることで、小さな測定対象物Bの外角の測定が可能となる。
Further, in a form in which a part of the plate surfaces of the rotor portions 6a and 7a are in contact with each other or close to each other, one angle measuring element 6 has one plate surface as shown in FIG. As shown in FIG. 9, the other angle measuring element 7 can be provided with two plate surfaces at an interval between the one angle measuring member 6 and one plate surface.
Then, as shown in FIGS. 10 and 11, the surface of the frictional middle plate 20 of the rotor portions 6a and 7a and a part of the frictional outer plates 21a and 21b on both sides thereof approach to each other to measure the rotational measurement surface. 8, 9 on both sides of the end portions 8 a, 9 a, 8 b, 9 b are overlapped with each other so that the rotation measurement surfaces 8, 9 intersect each other, and the rotation measurement surfaces 8, 9 intersect each other. Is applied to both outer angle surfaces of the measuring object B, the outer angle of the small measuring object B can be measured.

又、この形態での内角の測定では、前記ローター部6a、7aの擦違中板20の一部を相互に重なるようにして小さな測定対象物Aの内角の測定が可能となり、この場合、両回動測定面8、9の端部8a、9a同士が接触状態となると、その端部8a、9aを頂点として両内角面を最小範囲まで同時に密接させることができるので、極めて小さな測定対象物Aの内角の測定が可能となる。
なお、両回動測定面8、9の端部8a、9a同士が離れた状態であっても、その離れた距離より小さい測定対象物Aではその両内角面を両回動測定面8、9に同時に密接させることができないので、その場合には内角の測定ができなくなるが、回動測定面8、9が測定対象物Aの両内角面に同時に密接可能な限り、どのような大きさの測定対象物Aでもその内角の測定が可能となる。
なお、図示しないが、両方の角度測定子6のローター部6a、7aを1枚とし、両角度測定子6、7の板面の一部が接近して相互に重なるように形成した態様や、両方のローター部6a、7aのいずれも複数枚としたそれらローター部6a、7aの板面の一部が接近して相互に重なるようにした態様も可能である。
Further, in the measurement of the internal angle in this form, it becomes possible to measure the internal angle of the small measuring object A by overlapping a part of the rubbing middle plate 20 of the rotor portions 6a and 7a. When the end portions 8a and 9a of the rotation measuring surfaces 8 and 9 are in contact with each other, both the inner corner surfaces can be brought into close contact at the same time with the end portions 8a and 9a as apexes. It is possible to measure the inner angle of the.
Even when the end portions 8a and 9a of the both rotation measuring surfaces 8 and 9 are separated from each other, the inner surface of the measuring object A that is smaller than the distance between the two rotation measuring surfaces 8 and 9 is defined as the both rotation measuring surfaces 8 and 9. In this case, the inner angle cannot be measured. However, as long as the rotation measuring surfaces 8 and 9 can be in close contact with both inner angle surfaces of the measuring object A at the same time, the size of the inner angle cannot be measured. The measurement object A can also measure its inner angle.
Although not shown in the drawing, the rotor parts 6a and 7a of both angle measuring elements 6 are formed as one sheet, and a part of the plate surface of both angle measuring elements 6 and 7 is formed so as to be close to each other, It is also possible to adopt a mode in which a part of the plate surfaces of the rotor portions 6a and 7a, which are both a plurality of both rotor portions 6a and 7a, are close to each other and overlap each other.

又、測定には両角度測定子6、7に角度の測定基準となる位置を決めなければならないが、図7に示すように、両角度測定子6、7のローター部6a、7aの板面には、両角度測定子6、7の回動測定面8、9の両端部寄り部位に夫々ピン突当り部14a、14b、15a、15bを備えたピン逃がし面14、15を形成し、両回動支持体2、3の両角度測定子6、7の前記ピン逃がし面14、15に臨む部位には、前記角度測定子6、7の180度の回動位置で両側の前記ピン突当り部14a、14b、15a、15bに当たって停止する測定基準位置決めピン16、17、18、19を前記両回動支持体2、3の二股の分岐部に設けた形態が可能であり、これによって両角度測定子6、7の測定基準位置を決めることが可能となる。
図7では、前記ピン逃がし面14、15は前記ローター部6a、7aの板面の外周に添った円形の溝状に形成した態様を示しているが、夫々のピン突当り部14a、14b、15a、15bまでの間において、両ローター部6a、7aの板面に前記両回動支持体2、3に設けた測定基準位置決めピン16、17、18、19が当たらなければ良いので、図示しないが前記ローター部6a、7aに扇状の窪みや、板面を貫通した孔に形成しても良い。
In addition, for measurement, the position to be an angle measurement reference must be determined for both angle measuring elements 6 and 7, but as shown in FIG. 7, the plate surfaces of the rotor portions 6a and 7a of both angle measuring elements 6 and 7 are used. Are formed with pin relief surfaces 14 and 15 having pin abutting portions 14a, 14b, 15a and 15b, respectively, near the both end portions of the rotational measuring surfaces 8 and 9 of the angle measuring elements 6 and 7. At the portion of the moving support bodies 2 and 3 facing the pin relief surfaces 14 and 15 of the angle measuring elements 6 and 7, the pin contact portions 14a on both sides at the 180 degree rotation position of the angle measuring elements 6 and 7 are provided. , 14b, 15a, 15b, and the measurement reference positioning pins 16, 17, 18, 19 can be provided at the bifurcated branching portions of the rotary supports 2, 3, whereby both angle measuring elements are possible. 6 and 7 measurement reference positions can be determined.
FIG. 7 shows an embodiment in which the pin relief surfaces 14 and 15 are formed in a circular groove shape along the outer periphery of the plate surface of the rotor portions 6a and 7a, but the respective pin contact portions 14a, 14b and 15a are shown. , 15b, the measurement reference positioning pins 16, 17, 18, 19 provided on the rotary supports 2, 3 do not contact the plate surfaces of the rotor portions 6a, 7a. The rotor portions 6a and 7a may be formed in fan-shaped depressions or holes penetrating the plate surface.

この態様では、ローター部6a、7aのピン突当り部14a、14b、15a、15bに前記両回動支持体2、3に設けた測定基準位置決めピン16、17、18、19が当たって、前記角度測定子6、7が停止するので、両側ピン突当り部14a、14b、15a、15bを回動測定面8、9がお互いに平行に停止し、前記角度測定子6、7が正確に180度回動可能に停止位置を設定すれば測定精度高めることができる。
更に精度を高めてより正確な停止位置を決める場合には、測定基準位置決めピンに偏芯ピンを用いることができる。この場合、別の測定器で計測しつつ両側ピン突当り部14a、14b、15a、15bに偏芯ピンの偏芯部分を押し当てつつ該偏芯ピンを回転させ、両側の回動測定面8、9が正確に平行となる位置まで移動させる。このことで製造時に生じたピン突当り部14a、14b、15a、15bの誤差をより小さくなるものに修正することが可能となる。
In this embodiment, the pin contact portions 14a, 14b, 15a, 15b of the rotor portions 6a, 7a are contacted with the measurement reference positioning pins 16, 17, 18, 19 provided on the rotary supports 2, 3, so that the angle Since the measuring elements 6 and 7 are stopped, the rotation measuring surfaces 8 and 9 are stopped parallel to each other at the pin contact portions 14a, 14b, 15a and 15b on both sides, and the angle measuring elements 6 and 7 are rotated exactly 180 degrees. If the stop position is set to be movable, the measurement accuracy can be increased.
In order to further increase the accuracy and determine a more accurate stop position, an eccentric pin can be used as the measurement reference positioning pin. In this case, while measuring with another measuring device, the eccentric pin is rotated while pressing the eccentric portion of the eccentric pin against the both-side pin contact portions 14a, 14b, 15a, 15b, 9 is moved to a position where it is exactly parallel. This makes it possible to correct the errors of the pin contact portions 14a, 14b, 15a, and 15b generated at the time of manufacture to be smaller.

又、図12に示すように、前記基台1上で両回動支持体2、3間の間隔を拡縮可能とした態様が可能である。
この態様では、一直線のスライド平面27を備えた定規の如き長板状基台1aを用い、前記回動支持体2、3の少なくとも一方を該基台1aのスライド平面27に導かれて直立状態でスライド往復可能となるように装着する。
この形態では、前記回動支持体2、3の少なくとも一方に、前記基台1のスライド平面27に対して回動支持体2、3が直立状態で往復可能とするスライド孔28を形成し、スライド移動させた回動支持体2、3を任意の位置で固定する固定ネジ29を設ける。
Moreover, as shown in FIG. 12, the aspect which made it possible to expand / contract the space | interval between both the rotation support bodies 2 and 3 on the said base 1 is possible.
In this embodiment, a long plate-like base 1a such as a ruler having a straight slide plane 27 is used, and at least one of the rotation supports 2 and 3 is guided to the slide plane 27 of the base 1a and is in an upright state. Attach so that it can slide back and forth.
In this embodiment, at least one of the rotation supports 2 and 3 is formed with a slide hole 28 that allows the rotation supports 2 and 3 to reciprocate in an upright state with respect to the slide plane 27 of the base 1. A fixing screw 29 is provided for fixing the slidable rotation supports 2 and 3 at an arbitrary position.

この形態では、測定対象物Aの入隅に異物や変形が存在する内角面A1、A2であっても、間隔を広げることで異物や変形部分を跨いで測定すべき内角面A1、A2に回動測定面8、9を同時に当ててその角度xを測定することが可能となる。
また、測定対象物Bに異物や変形が存在する外角部分では、そこから離れた位置にある外角面B1、B2に対して回動測定面8、9を同時に当てることが可能となるので、その外角yを測定することが可能となる。
尚、図12中の符号34は、前記回動支持体2、3が基台1aから抜け落ちるのを防止する抜止め板34である。
In this embodiment, even if the inner corner surfaces A1 and A2 have foreign matters or deformations at the corners of the measurement object A, the interval is increased to the inner corner surfaces A1 and A2 to be measured across the foreign matter or deformed portions. It is possible to measure the angle x by simultaneously applying the dynamic measurement surfaces 8 and 9.
In addition, in the outer corner portion where the foreign object or deformation exists in the measurement object B, the rotational measurement surfaces 8 and 9 can be simultaneously applied to the outer corner surfaces B1 and B2 located away from the outer corner surface. It becomes possible to measure the outside angle y.
In addition, the code | symbol 34 in FIG. 12 is the retaining plate 34 which prevents the said rotation support bodies 2 and 3 falling off from the base 1a.

又、図13に示すように、前記回動支持体2、3を、両方又は一方を基台1から直立した方向に伸縮可能とする高さ調節部30を設けた形態が可能である。
該図13は、回動支持体2の一方に高さ調節部30を設けた態様である。
前記回動支持体2の伸縮は、棒状の回動支持体2の上部の中棒部31を下部の外筒部32内にスライド可能に嵌合させ、中棒部31を出没させることで前記回動支持体2が伸縮される。
そして、測定対象物の測定に適した位置にまで伸縮させたら外筒部32の側面に設けた固定ネジ33によってその位置で締め付けると中棒部31がその位置で固定される。
Moreover, as shown in FIG. 13, the form which provided the height adjustment part 30 which enables the said rotation support bodies 2 and 3 to expand-contract in the direction upright from the base 1 is possible for both or one side.
FIG. 13 is a mode in which a height adjusting unit 30 is provided on one side of the rotating support 2.
The expansion and contraction of the rotating support 2 is performed by fitting the middle rod portion 31 on the upper portion of the rod-shaped rotating support 2 into the lower outer cylinder portion 32 so that the middle rod portion 31 is raised and lowered. The rotating support 2 is expanded and contracted.
And if it extends and contracts to the position suitable for the measurement of a measuring object, if it tightens in that position with the fixing screw 33 provided in the side surface of the outer cylinder part 32, the center rod part 31 will be fixed in that position.

この形態では、測定対象物Aの鋭角な内角xの頂点から離れた深い位置に内角面A1、A2がある場合には、その深い位置で回動測定面8、9を同時に当てることができ、その内角xの測定が可能と成る。
又、先端が変形した測定対象物Bの鋭角部分(図示省略)では、そこから離れた位置にある外角面B1、B2に対して回動測定面8、9を同時に当てることができ、その外角yの測定が可能となる。
In this form, when there are inner angle surfaces A1 and A2 at a deep position away from the apex of the sharp inner angle x of the measurement object A, the rotation measurement surfaces 8 and 9 can be simultaneously applied at the deep position, The inner angle x can be measured.
In addition, at the acute angle portion (not shown) of the measuring object B whose tip is deformed, the rotation measurement surfaces 8 and 9 can be simultaneously applied to the outer angle surfaces B1 and B2 located away from the measurement object B. Measurement of y is possible.

又、図14に示すように、前記基台1に前記演算表示部23を固着した形態が可能である。
この形態では、前記演算表示部23を回動支持体2から分離させて基台1に固着した態様と、近い方の回動支持体2も基台1と一体に演算表示部23に固着させた態様とが可能である。
Moreover, as shown in FIG. 14, the calculation display part 23 can be fixed to the base 1.
In this embodiment, the calculation display unit 23 is separated from the rotation support 2 and fixed to the base 1, and the closer rotation support 2 is also fixed to the calculation display unit 23 integrally with the base 1. Are possible.

図14に示す形態では、演算表示部23が前記角度測定子6、7側と一体となるので、測定対象の機械装置や部品に対して片手だけで角度が測定できるので使い易くなる。
なお、前記演算表示部23と基台1とは着脱可能とすることも可能であり、その場合には測定対象物に応じて、両者を分離することで、コンパクトにした角度測定子6、7側の部分が狭い場所に差し込んで測定できるようになり便利である。
In the form shown in FIG. 14, since the calculation display unit 23 is integrated with the angle measuring elements 6 and 7, the angle can be measured with only one hand with respect to the mechanical device or component to be measured, which is easy to use.
The calculation display unit 23 and the base 1 can be detachable. In this case, the angle measuring elements 6 and 7 are made compact by separating the two according to the measurement object. It is convenient because the side part can be inserted into a narrow space and can be measured.

又、前記基台1に前記演算表示部23を固着し、前記基台1と前記演算表示部23とを一体化させると共に、一方の回動支持体2は前記基台1上を往復させて両角度測定子6、7間の間隔を拡縮可能とし、他方の回動支持体3は角度測定子7の高さを調節可能とした形態が可能である。   In addition, the calculation display unit 23 is fixed to the base 1, and the base 1 and the calculation display unit 23 are integrated, and one rotating support 2 is reciprocated on the base 1. A configuration is possible in which the distance between the angle measuring elements 6 and 7 can be enlarged and reduced, and the other rotation support 3 can adjust the height of the angle measuring element 7.

この形態では、例えば、図15の(イ)、(ロ)に示すように、内部に前記演算表示部23を備えた箱型の基台1の上面と側面には、それぞれスライド溝35、36を設ける。
又、前記上面のスライド溝35内にスライド可能に嵌合可能なL型に屈曲させて形成した一方のスライド部2dと、前記側面のスライド溝36内にスライド可能に嵌合可能なI型に長く形成した他方のスライド部3dを回動支持体2、3にそれぞれ形成し、該回動支持体2、3のスライド部2d、3dを前記各スライド溝35、36に嵌合させる。
そして、前記スライド部2d、3dにはスライド方向に長いスライド長孔37、38を形成し、該スライド長孔37、38を貫通させ、スライド溝35、36内に螺着可能な位置固定ネジ39、40を設け、スライド往復する範囲の任意の位置に該位置固定ネジ39、40で回動支持体2、3を固定可能とする。
In this embodiment, for example, as shown in FIGS. 15A and 15B, slide grooves 35 and 36 are respectively formed on the upper surface and the side surface of the box-shaped base 1 having the calculation display unit 23 therein. Is provided.
Also, one slide portion 2d formed by bending into an L shape that can be slidably fitted in the slide groove 35 on the upper surface, and an I type that can be slidably fitted in the slide groove 36 on the side surface. The other long slide part 3d is formed on the rotary supports 2 and 3, respectively, and the slide parts 2d and 3d of the rotary supports 2 and 3 are fitted into the slide grooves 35 and 36, respectively.
The slide portions 2d and 3d are formed with long slide long holes 37 and 38 in the slide direction, penetrated through the long slide holes 37 and 38, and can be screwed into the slide grooves 35 and 36. , 40, and the rotation support bodies 2, 3 can be fixed to the arbitrary positions within the range of reciprocating slide by the position fixing screws 39, 40.

この形態による角度の測定は、測定対象物Aの内角や外角の形状に応じて前記基台1に対して両回動支持体2、3を適宜移動させ、測定に最適な位置の内角面や外角面に両回動測定面8、9を同時に押し当てて角度を測定する。
図15の(イ)は一方の回動支持体2を基台1の上面にスライドさせて両回動測定面8、9間を開くと共に他方の回動支持体3を基台1の側面から上に高く突出させた状態を示し、(ロ)は両回動測定面8、9同士を密接させて測定基準の位置決めをしている状態を示している。
なお、該図15では、前記演算表示部23内の構造は省略した。
In the measurement of the angle according to this form, the two rotation supports 2 and 3 are appropriately moved with respect to the base 1 according to the shape of the inner angle and the outer angle of the measuring object A, The angle is measured by simultaneously pressing the two rotation measuring surfaces 8 and 9 against the outer angle surface.
In FIG. 15A, one rotation support body 2 is slid on the upper surface of the base 1 to open between both rotation measurement surfaces 8 and 9 and the other rotation support body 3 is opened from the side surface of the base 1. A state of projecting high upward is shown, and (B) shows a state where the two measurement surfaces 8 and 9 are brought into close contact with each other and the measurement reference is positioned.
In FIG. 15, the structure inside the calculation display unit 23 is omitted.

次に本発明の上記全角度測定器を用いた角度の測定の方法について説明する。
本発明では、内角x及び外角yの角度は、測定対象物に対して基台1を傾けても、両回動測定面8、9の各傾斜角度の数値は変わるが、角度の測定は挟む二面の角度関係だけから導き出すものなので、内角x及び外角y自体の算出される角度は同じ数値となる。
このため、周囲に障害物があったり狭かったりして計測し難い部分の測定でも、測定対象物に対して角度測定器の位置や角度を柔軟に対応させて計測することが可能となる。
Next, a method for measuring an angle using the above-described full angle measuring device of the present invention will be described.
In the present invention, the angle of the inner angle x and the outer angle y is changed even if the base 1 is tilted with respect to the object to be measured. Since the angle is derived only from the angular relationship between the two surfaces, the calculated angles of the inner angle x and the outer angle y themselves are the same numerical value.
For this reason, even in the measurement of a portion that is difficult to measure due to obstacles or narrow surroundings, the position and angle of the angle measuring device can be flexibly associated with the measurement object.

そして、測定に当たっては、内角も外角も両方の角度測定子6、7の回動測定面8、9の異なる傾斜角度から算出されるものであるので、先ず読み取る数値の基準となる状態を、両側の回動測定面8、9が同一直線上にある場合と平行線上にある場合を回動測定面8、9の基準とし、このときの数値を「0」度又は「180」度として前記演算表示部11に記憶させる。   In the measurement, since both the inner angle and the outer angle are calculated from different inclination angles of the rotation measuring surfaces 8 and 9 of both the angle measuring elements 6 and 7, first, a state serving as a reference for the numerical value to be read is set on both sides. When the rotation measurement surfaces 8 and 9 are on the same straight line and parallel lines, the rotation measurement surfaces 8 and 9 are used as a reference, and the numerical value at this time is set to “0” degrees or “180” degrees. It is stored in the display unit 11.

回動測定面8、9が同一直線上にある場合とは、図15の(ロ)に示すように、一平面に対して両側の角度測定子6、7の回動測定面8、9が同時に密接状態に押し当てられている状態であり、平行線上にある場合とは、両側に平行面を有する板や立方体等の平行面に両側の角度測定子6、7の回動測定面8、9が同時に密接状態に押し当てられている状態である。
又、平行線上にある場合では、前記角度測定子6、7の180度の回動位置で両側の前記ピン突当り部14a、14b、15a、15bに当たって停止する測定基準位置決めピン16、17、18、19を設けた形態では、測定基準位置決めピン16、17、18、19が前記ピン突当り部14a、14b、15a、15bに突き当たって停止する状態である。
When the rotation measuring surfaces 8 and 9 are on the same straight line, as shown in FIG. 15B, the rotation measuring surfaces 8 and 9 of the angle measuring elements 6 and 7 on both sides with respect to one plane are provided. In the case of being in close contact with each other at the same time and being on a parallel line, the rotation measuring surfaces 8 of the angle measuring elements 6 and 7 on both sides of a parallel surface such as a plate or a cube having parallel surfaces on both sides, 9 is a state where it is pressed in close contact at the same time.
In the case of being on parallel lines, the measurement reference positioning pins 16, 17, 18, which stop by hitting the pin abutting portions 14 a, 14 b, 15 a, 15 b on both sides at the 180 degree rotation position of the angle measuring elements 6, 7, In the form in which 19 is provided, the measurement reference positioning pins 16, 17, 18, 19 are in contact with the pin contact portions 14a, 14b, 15a, 15b and stop.

該測定基準位置決めピン16、17、18、19を備えた形態を除いて、前記磁気センサー12a、13aに対する両側の角度測定子6、7の基準位置は一箇所には決まっておらず、測定する都度測定基準位置を変えても良いし、同じ位置を継続しても良い。   Except for the configuration provided with the measurement reference positioning pins 16, 17, 18, and 19, the reference positions of the angle measuring elements 6 and 7 on both sides with respect to the magnetic sensors 12a and 13a are not determined in one place and are measured. The measurement reference position may be changed each time, or the same position may be continued.

(測定例)
次に、内角及び外角の測定方法について、図を参照して具体的に数値を用いて説明する。
(A)例えば、測定の準備として両方の回動測定面8、9を一平面に同時に押し当て測定基準「180度」を設定し、両方時計回り方向で測定した場合について説明する。
測定する角度は同じ時計回りとする方向では、一方はマイナスの数値となるが、いずれも絶対値として加算して算出する。
(Measurement example)
Next, a method for measuring the inner angle and the outer angle will be described using specific numerical values with reference to the drawings.
(A) For example, as a preparation for measurement, a case will be described in which both rotational measurement surfaces 8 and 9 are simultaneously pressed against one plane to set the measurement standard “180 degrees” and both are measured in the clockwise direction.
In the direction in which the angle to be measured is the same clockwise direction, one becomes a negative numerical value, but both are calculated as absolute values.

a)内角の測定について
測定対象物Aの内角xの測定では,例えば、図5に示すように、測定対象物Aの両内角面A1、A2に回動測定面8、9を同時に押し当てて、前記測定基準に対して、実測すると、一方の回動測定面8の傾斜角度が−30.18度で他方の回動測定面9の傾斜角度+57.87度と読み取れる。
この場合は読み取った両方に数値を加えて、基準値の180から差し引いて算出し、180−(30.18+57.87)=91.95の演算により91.95度と測定され、その数値が液晶表示部にデジタル数字で表示される。
a) Measurement of internal angle In measurement of the internal angle x of the measurement object A, for example, as shown in FIG. 5, the rotational measurement surfaces 8 and 9 are simultaneously pressed against both internal angle surfaces A1 and A2 of the measurement object A. When actually measured with respect to the measurement standard, the inclination angle of one rotation measurement surface 8 is −30.18 degrees, and the inclination angle of the other rotation measurement surface 9 is +57.87 degrees.
In this case, a numerical value is added to both of the readings and subtracted from the reference value of 180, and is calculated to be 91.95 degrees by an operation of 180− (30.18 + 57.87) = 91.95. Displayed as digital numbers on the display.

b)外角の測定について
測定対象物Bの外角yの測定では、例えば、図6に示すように、測定対象物Bの両外角面B1、B2に回動測定面8、9を同時に押し当てて、前記測定基準に対して、実測すると、一方の回動測定面8の傾斜角度が+60.38度で他方の回動測定面9の傾斜角度が−39.81度と読み取った場合、180−(60.38+39.81)=79.81の演算により79.81度と測定され、その数値が液晶表示部にデジタル数字で表示される。
b) Measurement of outside angle In the measurement of the outside angle y of the measuring object B, for example, as shown in FIG. 6, the rotational measuring surfaces 8 and 9 are simultaneously pressed against both the outside angle surfaces B1 and B2 of the measuring object B. When actually measured with respect to the measurement standard, when the inclination angle of one rotation measurement surface 8 is +60.38 degrees and the inclination angle of the other rotation measurement surface 9 is read as −39.81 degrees, 180− It is measured as 79.81 degrees by the calculation of (60.38 + 39.81) = 79.81, and the numerical value is displayed as a digital number on the liquid crystal display unit.

尚、基準設定のため回動測定面8、9を同時に押し当てる一平面は、前記回動支持体2、3に対して垂直である場合や傾斜した場合があるが、その傾斜に応じて、両方の数値は変化しても、同じ内角及び外角の測定では、その算出された数値は別傾斜にして何度計測しても測定結果は同じとなる。
このため、測定対象物に対して、測定場所の環境に合わせて前記回動支持体2、3を傾斜させて測定することが可能となる。
Note that one plane for simultaneously pressing the rotation measurement surfaces 8 and 9 for reference setting may be perpendicular or inclined with respect to the rotation supports 2 and 3, but depending on the inclination, Even if both numerical values are changed, in the measurement of the same inner angle and outer angle, the measured results are the same no matter how many times the calculated numerical values are set with different inclinations.
For this reason, it becomes possible to measure the object to be measured by inclining the rotation supports 2 and 3 according to the environment of the measurement place.

(B)次に、測定の準備として両方の回動測定面8、9を回動支持体2の直立方向と平行に位置決めして測定基準「0度」を設定して測定した場合について説明する。
測定する角度は同じ時計回り方向での測定値は、一方ではマイナスとなるが、いずれも絶対値として加算して算出する。
この方法では、直方形の物体を挟んで、回動支持体2の直立方向と略平行に回動測定面8、9の位置決めをして、その位置を測定基準「0度」と設定して測定した形態と、両角度測定子の板面にピン突当り部を備えたピン逃がし面を設け、両回動支持体の両角度測定子に測定基準位置決めピンを設け、前記回動支持体2の直立方向と略平行に回動測定面8、9の位置決で測定基準「0度」と設定して測定した形態が可能である。
(B) Next, as a preparation for measurement, a case where both the rotation measurement surfaces 8 and 9 are positioned in parallel with the upright direction of the rotation support 2 and the measurement standard “0 degree” is set will be described. .
The measured values in the same clockwise direction are negative on the one hand, but both are calculated as absolute values.
In this method, the rotation measurement surfaces 8 and 9 are positioned substantially parallel to the upright direction of the rotation support body 2 with a rectangular object sandwiched therebetween, and the position is set as a measurement reference “0 degree”. The measured form and the pin relief surface provided with the pin contact portion are provided on the plate surface of both angle measuring elements, the measurement reference positioning pins are provided on both angle measuring elements of both rotating supports, It is possible to adopt a form in which measurement is performed by setting the measurement reference “0 degree” by positioning the rotational measurement surfaces 8 and 9 substantially parallel to the upright direction.

a)後者の場合は、前記角度測定子6、7の測定基準は、前記測定基準位置決めピンがピン突当り部に当たった位置とするので、測定基準の設定はせずに測定できる。
即ち、回動測定面8、9を向かい合わせ、又は背中合わせにした位置を測定基準「0度」と設定し、例えば、外角の測定では、回動測定面8、9を向かい合わせ位置を測定基準「0度」と設定し、内角の測定では、回動測定面8、9を背中合わせ位置で測定基準「0度」と設定することができる。
そして、一方を時計回り方向をプラスの数値とし、他方を反時計回り方向をプラスの数値に設定して測定すると、その数値の加算で測定値が算出できる。
a) In the latter case, the measurement reference of the angle measuring elements 6 and 7 is the position where the measurement reference positioning pin hits the pin abutting portion, so that measurement can be performed without setting the measurement reference.
That is, the position where the rotation measurement surfaces 8 and 9 face each other or back to back is set as a measurement reference “0 degree”. For example, in the measurement of an external angle, the position where the rotation measurement surfaces 8 and 9 face each other is the measurement reference. In the measurement of the internal angle, the rotation measurement surfaces 8 and 9 can be set to the measurement reference “0 degree” at the back-to-back position.
Then, when one is measured with the clockwise direction set as a positive numerical value and the other set with the counterclockwise direction set as a positive numerical value, the measured value can be calculated by adding the numerical values.

b)いずれの場合でも、例えば、図5に示すように、測定対象物Aの両内角面A1、A2に回動測定面8、9を同時に押し当てて、一方の回動測定面8の傾斜角度が59.82度で他方の回動測定面9の傾斜角度が32.13度と読み取った場合、59.82+32.13=91.95の演算により91.95度と測定され液晶表示部にデジタル数字で表示される。
測定対象物Bの外角の測定では、例えば、図6に示すように、回動測定面8、9を両外角面B1、B2に同時に押し当てて、一方の回動測定面8の傾斜角度が29.62度で他方の回動測定面9の傾斜角度が50.19度と読み取った場合、29.62+50.19=79.81の演算により79.81度と測定され液晶表示部にデジタル数字で表示される。
b) In any case, for example, as shown in FIG. 5, the rotation measurement surfaces 8 and 9 are simultaneously pressed against both the inner angular surfaces A1 and A2 of the measurement object A, and the one rotation measurement surface 8 is inclined. When the angle is 59.82 degrees and the tilt angle of the other rotation measuring surface 9 is read as 32.13 degrees, it is measured to be 91.95 degrees by the calculation of 59.82 + 32.13 = 91.95. Displayed in digital numbers.
In the measurement of the external angle of the measuring object B, for example, as shown in FIG. 6, the rotational measurement surfaces 8 and 9 are pressed against both external angular surfaces B1 and B2 at the same time, and the inclination angle of one rotational measurement surface 8 is When the tilt angle of the other rotation measuring surface 9 is read as 50.19 degrees at 29.62 degrees, it is measured as 79.81 degrees by the calculation of 29.62 + 50.19 = 79.81, and the digital number is displayed on the liquid crystal display unit. Is displayed.

以上で本発明の磁気センサーを用いた形態を説明したので、次に光センサーを用いた形態を説明する。
この形態は、上記磁気センサーを用いた形態とは光センサーを用いた点で異なっているが、その他の態様や、使用方法は磁気センサーを用いた形態と同じであるのでその説明は省略し、発明の構成及び光センサー部分について以下で詳しく説明する。
The embodiment using the magnetic sensor of the present invention has been described above. Next, the embodiment using the optical sensor will be described.
This form differs from the form using the magnetic sensor in that an optical sensor is used, but other aspects and usage are the same as the form using the magnetic sensor, so the description thereof is omitted. The configuration of the invention and the optical sensor portion will be described in detail below.

この形態は、図16に示すように、基台1上に平行に突設した一対の回動支持体2、3の各先端寄り部位に、磁気センサーを用いた形態と同様に、該先端部を二股とした支持部2a、3aを形成する。
そして、該支持部2a、3aに、図18の(イ)及び(ロ)に示すように、内部に設けたベアリング軸受44を介して両枢支軸4a、5aが対向して平行となるように計測ケース50、50を固着し、該計測ケース50、50の内部には角度計測用空間を備える。

図18中の符号43はベアリング軸受44のボール43である。
As shown in FIG. 16, this form is similar to the form using a magnetic sensor at each tip end portion of a pair of rotating supports 2, 3 projecting in parallel on the base 1. The support portions 2a and 3a having a bifurcated shape are formed.
Then, as shown in FIGS. 18A and 18B, the pivot shafts 4a and 5a are opposed to and parallel to the support portions 2a and 3a through bearing bearings 44 provided therein. The measurement cases 50 and 50 are fixed to each other, and an angle measurement space is provided inside the measurement cases 50 and 50.

そして、前記枢支軸4a、5aの他方端部を前記ベアリング軸受44から突出させて、該突出部に、該枢支軸4a、5aに対する垂直な線と平行な回動測定面8、9と、該回動測定面8、9を支持する優弧半円板状のローター部6a、7aとを備えた角度測定子6、7を夫々固着する。
その際、両回動測定面8、9を、図16に示すように、前記各回動支持体2、3を避けてその先端部及び両側面部よりも外側の全周に亘って回動可能に形成する。
Then, the other end portions of the pivot shafts 4a and 5a are projected from the bearing bearing 44, and the rotation measuring surfaces 8 and 9 parallel to a line perpendicular to the pivot shafts 4a and 5a are projected on the projection portions. The angle measuring elements 6 and 7 having the semicircular disk-shaped rotor portions 6a and 7a for supporting the rotation measuring surfaces 8 and 9 are fixed.
At that time, as shown in FIG. 16, both the rotation measuring surfaces 8 and 9 can be rotated over the entire circumference outside the front end portion and both side surface portions while avoiding the rotation support bodies 2 and 3. Form.

又、測定する際には両角度測定子6、7の測定基準となる位置を設定するが、図17に示すように、両角度測定子6、7のローター部6a、7aの板面に、両角度測定子6、7の回動測定面8、9の両端部寄り部位には夫々ピン突当り部14a、14b、15a、15bを備えたピン逃がし面14、15を形成し、両回動支持体2、3の両角度測定子6、7の前記ピン逃がし面14、15に臨む部位には、前記角度測定子6、7の180度の回動位置で両側の前記ピン突当り部14a、14b、15a、15bに当たって停止する測定基準位置決めピン16、17、18、19を前記両回動支持体2、3の二股の分岐部に設けた形態が可能であり、これによって両角度測定子6、7の測定基準位置を決めることが可能となる。
この測定基準位置の決め方は、上記磁気センサーを用いた形態と同様である。
なお、図17におけるX−X線縦断側面図を示す図18の(イ)に示すよう、前記角度検出部41の枢支軸4a、5aは、回動支持体2、3の各先端寄り部位の二股とした先端部の二股のうち角度検出部41の設けない対向側には枢支しない態様も可能である。
Moreover, when measuring, the position which becomes the measurement reference | standard of both angle measuring elements 6 and 7 is set, but as shown in FIG. 17, on the plate | board surface of the rotor parts 6a and 7a of both angle measuring elements 6 and 7, Pin relief surfaces 14 and 15 having pin contact portions 14a, 14b, 15a, and 15b are formed at positions near both ends of the rotational measurement surfaces 8 and 9 of both angle measuring elements 6 and 7, respectively, and both rotational supports are provided. On the part of the body 2, 3 facing the pin relief surfaces 14, 15 of the angle measuring elements 6, 7, the pin contact portions 14a, 14b on both sides at the 180 degree rotation position of the angle measuring elements 6, 7 are provided. , 15a, 15b, and the measurement reference positioning pins 16, 17, 18, 19 can be provided at the bifurcated branching portions of the two rotation supports 2, 3, whereby both angle measuring elements 6, 7 measurement reference positions can be determined.
The method of determining the measurement reference position is the same as that using the magnetic sensor.
In addition, as shown in FIG. 18 (a) showing a vertical cross-sectional side view taken along the line XX in FIG. 17, the pivot shafts 4a and 5a of the angle detection unit 41 are located closer to the respective tips of the rotation supports 2 and 3. Of the two forks at the front end of the two, a mode in which the angle detection unit 41 is not provided is also possible.

そして、前記両角度センサー49に接続させて、両光センサー49で感知した各傾斜角度のデータからプログラムに従って演算処理する電子演算部24とその演算結果をデジタル表示する液晶表示部25とを備えた演算表示部23を設ける。   An electronic operation unit 24 that is connected to the angle sensor 49 and performs arithmetic processing according to a program from data of each inclination angle sensed by the both light sensors 49 and a liquid crystal display unit 25 that digitally displays the operation result are provided. A calculation display unit 23 is provided.

なお、上記磁気センサーと用いた形態では、ローター部6a、7aに磁気目盛面10、11を有するのでローター部6a、7aの形状を優弧半円板状としたが、上記光センサーを用いた形態では前記ローター部6a、7aに磁気目盛帯10a、11a等の目盛りを設けないのでローター部6a、7aの形状は優弧半円板状と特定する必要はない。
前記ローター部6a、7aは前記光センサー49を備えた角度検出部41を枢支軸4a、5a部分に組み込んで回動測定面8、9を一定の位置に回動可能に支持するものであり、回動測定面8、9を棒状とした場合には、ローター部6a、7aの形状は優弧半円板状とすることもできるが円板状、矩形等各種形状に形成することが可能である。
In the form used with the magnetic sensor, the rotor parts 6a and 7a have the magnetic scale surfaces 10 and 11, and thus the rotor parts 6a and 7a have a semicircular disk shape. However, the optical sensor is used. In the embodiment, since the scales such as the magnetic graduation bands 10a and 11a are not provided on the rotor parts 6a and 7a, it is not necessary to specify the shape of the rotor parts 6a and 7a as a semi-circular disk shape.
The rotor parts 6a and 7a are configured to incorporate an angle detection part 41 provided with the optical sensor 49 in the pivot shafts 4a and 5a so as to rotatably support the rotation measuring surfaces 8 and 9 at a fixed position. When the rotation measuring surfaces 8 and 9 are rod-shaped, the shape of the rotor portions 6a and 7a can be a semi-circular disc shape, but it can be formed in various shapes such as a disc shape and a rectangular shape. It is.

次に、前記角度検出部41をその一例を示す図18の模式図で説明する。
該角度検出部41は、図18の(ロ)に示すように、前記計測ケース50内の前記枢支軸4a、5aの角度計測空間への突出部には、回転偏光板45を固設する。
そして、前記回転偏光板45に対して平行に固定偏光板46を前記計測ケース50の内壁に固設する。
又、前記計測ケース50内の固定偏光板46側の空間に臨む部位に該固定偏光板46に向けて光を照射する発光体48を設ける。
そして、該発光体48の照射で前記回転偏光板45と固定偏光板46とを通過した光を受ける位置に光の量を感知する光センサー49を設ける。
Next, the angle detector 41 will be described with reference to the schematic diagram of FIG.
As shown in FIG. 18B, the angle detector 41 has a rotating polarizing plate 45 fixed to a protruding portion of the pivot shafts 4a and 5a into the angle measurement space in the measurement case 50. .
A fixed polarizing plate 46 is fixed to the inner wall of the measurement case 50 in parallel with the rotating polarizing plate 45.
In addition, a light emitting body 48 for irradiating light toward the fixed polarizing plate 46 is provided at a portion facing the space on the fixed polarizing plate 46 side in the measurement case 50.
Then, an optical sensor 49 that senses the amount of light is provided at a position that receives light that has passed through the rotating polarizing plate 45 and the fixed polarizing plate 46 by irradiation of the light emitter 48.

前記発光体48にはLEDランプが使用でき、そのLEDランプの電源はデータ受信回路と共に帯状に形成された回路接続用ハーネス42によって電子演算部24に接続される。
そして、該発光体48から前記固定偏光板46に向けて光を照射(図中矢印で示す)すると、その光は該固定光板46通過して回転偏光板45へ向かい、該回転偏光板45を通過し、その先に設けた反射鏡47で反射され、光センサー49に届き、その光量が感知される。
その際に回転偏光板45が回転すると前記回転偏光板45と固定偏光板46の相対的な偏光方向が変化して光の透過量が変化するが、この光の変化量を光センサー49で感知し、そのデータを角度に換算して前記回転偏光板45に固定された角度測定子6、7の両回動測定面8、9の傾斜角度を電子演算部24で演算処理し、演算結果を液晶表示部25にデジタル表示する。
なお、前記角度検出部41は、前記発光体48から反射鏡47を用いずに前記固定偏光板46と回転偏光板45を通過した光が直接届く位置に光センサー49に配設した態様や、複数の固定偏光板と、それに対応した複数の光センサー49を用いた態様も可能であり、その構造は上記態様に限定されるものではない。
又、本発明の光センサー49による形態における内角及び外角の測定方法は、上記磁気センサーによる形態と同様である。
An LED lamp can be used as the light emitter 48, and the power source of the LED lamp is connected to the electronic calculation unit 24 by a circuit connection harness 42 formed in a strip shape together with a data receiving circuit.
Then, when light is irradiated from the light emitter 48 toward the fixed polarizing plate 46 (indicated by an arrow in the figure), the light passes through the fixed light plate 46 toward the rotating polarizing plate 45 and passes through the rotating polarizing plate 45. The light passes through, is reflected by the reflecting mirror 47 provided at the tip, reaches the optical sensor 49, and the amount of light is detected.
At this time, when the rotating polarizing plate 45 rotates, the relative polarization direction of the rotating polarizing plate 45 and the fixed polarizing plate 46 changes to change the light transmission amount. The light sensor 49 detects this light change amount. Then, the data is converted into an angle, and the tilt angle of both rotation measuring surfaces 8 and 9 of the angle measuring elements 6 and 7 fixed to the rotary polarizing plate 45 is calculated by the electronic calculation unit 24, and the calculation result is obtained. Digital display on the liquid crystal display unit 25.
In addition, the angle detection unit 41 may be disposed in the optical sensor 49 at a position where the light passing through the fixed polarizing plate 46 and the rotating polarizing plate 45 directly reaches the light emitting body 48 without using the reflecting mirror 47, An embodiment using a plurality of fixed polarizing plates and a plurality of optical sensors 49 corresponding thereto is also possible, and the structure thereof is not limited to the above embodiment.
In addition, the measuring method of the inner angle and the outer angle in the embodiment using the optical sensor 49 of the present invention is the same as the embodiment using the magnetic sensor.

以上前記角度検出部41を、発光体48から照射する光を回転偏光板45と固定偏光板46を通過させてその光の変化量を光センサー49で感知する形態で説明したが、本発明では回転偏光板45や固定偏光板46等の偏光板は使用しない態様も可能である。
例えば、計測ケース50の角度計測空間内に枢支軸4a、5aを中心に複数等分度間隔とした放射状のスリットを有する2枚の目盛り円板を両側のスリットが重ね合わされるように配し、該目盛り円板の一方は枢支軸4a、5aの突出部に固着し、他方は計測ケース50に固着する。
そして、一方の目盛り円板側の角度計測空間内に発光体を設け、他方の目盛り円板側にスリットを通過した光の量を感知する光センサーを設けた態様が可能である。
この態様では、測定する際に測定対象物に回動測定面8、9が当接するまで角度測定子6、7が回動すると前記枢支軸4a、5aの回動で一方の目盛り円板が他方の目盛り円板に対して相対的に回転して目盛り円板同士のスリットの開閉が起こり、発光体から目盛り円板に向けて照射した光がスリットを通過して光センサーで感知されるが、その際に発光体から目盛り円板に向けて照射した光のスリットからの通過量が増減し、その光の量の変化が光センサーで感知され、その感知されたデータから角度の計測が可能となる。
The angle detection unit 41 has been described above in the form in which the light emitted from the light emitter 48 passes through the rotating polarizing plate 45 and the fixed polarizing plate 46 and the amount of change in the light is detected by the optical sensor 49. A mode in which a polarizing plate such as the rotating polarizing plate 45 and the fixed polarizing plate 46 is not used is also possible.
For example, in the angle measurement space of the measurement case 50, two graduation disks having radial slits with a plurality of equally spaced intervals around the pivot shafts 4a and 5a are arranged so that the slits on both sides are overlapped. One of the scale disks is fixed to the projecting portion of the pivot shafts 4a and 5a, and the other is fixed to the measurement case 50.
In addition, a mode in which a light emitter is provided in the angle measurement space on one scale disk side and an optical sensor for sensing the amount of light passing through the slit is provided on the other scale disk side is possible.
In this aspect, when the angle measuring elements 6 and 7 are rotated until the rotation measuring surfaces 8 and 9 are brought into contact with the measurement object at the time of measurement, one scale disk is rotated by the rotation of the pivot shafts 4a and 5a. The slits between the scale disks rotate and rotate relative to the other scale disk, and the light emitted from the light emitter toward the scale disk passes through the slit and is detected by the optical sensor. At that time, the amount of light passing through the slit from the light emitter to the graduation disk increases and decreases, the change in the amount of light is detected by the optical sensor, and the angle can be measured from the detected data. It becomes.

本発明の全角度測定器は、精密部品等の測定対象物の両内角及び両外角に対して夫々回動測定面を同時に当てて測定するものであるが、分度器の如く設計図面上での各部の角度の測定もでき、又建築や土木の分野等、内角と外角の角度の測定に広く使用することが可能である。   The full-angle measuring instrument of the present invention measures the rotational measurement surfaces simultaneously with respect to both the internal and external angles of a measurement object such as a precision part, but each part on the design drawing like a protractor. It is also possible to measure the angle of the inner angle and the outer angle in the field of construction and civil engineering.
