Description

本発明は、同軸度を測定する同軸度測定装置に関するものである。   The present invention relates to a coaxiality measuring device for measuring coaxiality.

従来、同軸度を測定する場合、３次元測定器を用いるのが一般的である。因みに、３次元測定器で同軸度を測定する場合は、１つのセンサを第１円筒部のある断面において周方向に動かして、円周上の複数点で第１円筒部における外周面の径方向位置を測定し、さらにセンサを第２円筒部のある断面において周方向に動かして、円周上の複数点で第２円筒部における外周面の径方向位置を測定する。   Conventionally, when measuring the coaxiality, a three-dimensional measuring device is generally used. Incidentally, when measuring the coaxiality with a three-dimensional measuring device, one sensor is moved in the circumferential direction in a cross section of the first cylindrical portion, and the radial direction of the outer peripheral surface of the first cylindrical portion at a plurality of points on the circumference. The position is measured, and the sensor is further moved in the circumferential direction in a cross section of the second cylindrical portion, and the radial position of the outer peripheral surface of the second cylindrical portion is measured at a plurality of points on the circumference.

しかしながら、３次元測定器で同軸度を測定する場合は、１つのセンサを測定個所に順に移動させて多点の測定をするため、測定時間が長くなってしまうという問題があった。   However, when measuring the coaxiality with a three-dimensional measuring instrument, there is a problem that the measurement time becomes long because one sensor is sequentially moved to a measurement location to measure multiple points.

本発明は上記点に鑑みて、短時間で同軸度を測定可能にすることを目的とする。   The present invention has been made in view of the above points, and has an object to make it possible to measure the coaxiality in a short time.

上記目的を達成するため、請求項１に記載の発明では、ワーク（１）における第１円筒部（１１）と第２円筒部（１２）の同軸度を測定する同軸度測定装置であって、ワーク（１）を載せるワーク受け台（２）と、ワーク受け台（２）にワーク（１）を載せた状態で、ワーク（１）を所定の回転位置に順に回転させる回転機構（３）と、第１円筒部（１１）における外周面の径方向位置を測定する第１センサ（４１）と、第２円筒部（１２）における外周面の径方向位置を測定する第２センサ（４２）と、回転機構（３）からの回転位置データおよび第１、第２センサ（４２）の測定データに基づいて第１円筒部（１１）と第２円筒部（１２）の同軸度を演算する演算手段（６）とを備えることを特徴とする。   In order to achieve the above object, the invention according to claim 1 is a coaxiality measuring device for measuring the coaxiality of the first cylindrical portion (11) and the second cylindrical portion (12) in the work (1), A work cradle (2) for placing the work (1), and a rotation mechanism (3) for sequentially rotating the work (1) to a predetermined rotational position while the work (1) is placed on the work cradle (2). A first sensor (41) for measuring the radial position of the outer peripheral surface of the first cylindrical portion (11), and a second sensor (42) for measuring the radial position of the outer peripheral surface of the second cylindrical portion (12). Calculating means for calculating the coaxiality of the first cylindrical portion (11) and the second cylindrical portion (12) based on the rotational position data from the rotating mechanism (3) and the measurement data of the first and second sensors (42). (6).

これによると、第１円筒部を測定するセンサと第２円筒部を測定するセンサとを備えているため、第１円筒部と第２円筒部を同時に測定することができ、したがって、短時間で同軸度を測定することができる。   According to this, since the sensor for measuring the first cylindrical portion and the sensor for measuring the second cylindrical portion are provided, the first cylindrical portion and the second cylindrical portion can be measured at the same time. The coaxiality can be measured.

また、ワークを所定の回転位置に順に回転させるため、円筒部の周方向に沿って多数のセンサを配置する必要がなく、したがって、センサ数を少なくすることができる。   In addition, since the workpiece is sequentially rotated to a predetermined rotational position, there is no need to arrange a large number of sensors along the circumferential direction of the cylindrical portion, and therefore the number of sensors can be reduced.

請求項２に記載の発明のように、第１センサ（４１）を軸方向にずらして２つ配置することにより、データム円筒部に相当する第１円筒部の軸を求めることができる。   As in the second aspect of the invention, by disposing two first sensors (41) in the axial direction, the axis of the first cylindrical portion corresponding to the datum cylindrical portion can be obtained.

請求項３に記載の発明では、回転機構（３）は、ワーク（１）を３個所の回転位置に順に回転させることを特徴とする。   The invention according to claim 3 is characterized in that the rotating mechanism (3) sequentially rotates the work (1) to three rotational positions.

最低３個所の回転位置にて測定を行えば中心を求めることができるため、請求項３に記載の発明によると、最小の測定時間で中心を求めることができる。   Since the center can be obtained by performing measurement at at least three rotational positions, the center can be obtained with the minimum measurement time.

請求項４に記載の発明では、ワーク（１）における第１円筒部（１１）と第２円筒部（１２）の同軸度を測定する同軸度測定装置であって、第１円筒部（１１）の周方向に沿って少なくとも３つ配置されて、第１円筒部（１１）における外周面の径方向位置を測定する第１センサ（４１）と、第２円筒部（１２）の周方向に沿って少なくとも３つ配置されて、第２円筒部（１２）における外周面の径方向位置を測定する第２センサ（４２）と、第１および第２センサ（４２）の測定データに基づいて第１円筒部（１１）と第２円筒部（１２）の同軸度を演算する演算手段（６）とを備えることを特徴とする。   In invention of Claim 4, it is a coaxiality measuring apparatus which measures the coaxiality of the 1st cylindrical part (11) and 2nd cylindrical part (12) in a workpiece | work (1), Comprising: 1st cylindrical part (11) The first sensor (41) that measures at least three radial positions of the outer circumferential surface of the first cylindrical portion (11) and the circumferential direction of the second cylindrical portion (12) are arranged along the circumferential direction of the first cylindrical portion (11). And at least three, a second sensor (42) for measuring the radial position of the outer peripheral surface of the second cylindrical portion (12), and a first data based on measurement data of the first and second sensors (42). It is provided with the calculating means (6) which calculates the coaxiality of a cylindrical part (11) and a 2nd cylindrical part (12).

これによると、同軸度を測定するために必要なデータを同時に得ることができるため、極めて短時間で同軸度を測定することができる。   According to this, since data necessary for measuring the coaxiality can be obtained at the same time, the coaxiality can be measured in an extremely short time.

なお、上記各手段の括弧内の符号は、後述する実施形態に記載の具体的手段との対応関係を示すものである。   In addition, the code | symbol in the bracket | parenthesis of each said means shows the correspondence with the specific means as described in embodiment mentioned later.

（第１実施形態）
本発明の第１実施形態について説明する。図１は第１実施形態に係る同軸度測定装置の構成を模式的に示す正面図、図２は図１の装置の要部の側面図である。 (First embodiment)
A first embodiment of the present invention will be described. FIG. 1 is a front view schematically showing the configuration of the coaxiality measuring apparatus according to the first embodiment, and FIG. 2 is a side view of the main part of the apparatus of FIG.

図１、図２に示すように、被測定物であるワーク１は、円筒形状の第１円筒部１１と、円筒形状の第２円筒部１２と、両円筒部１１、１２間に配置されたセパレータ１３とを備え、それらは溶接等にて一体化されている
測定の際には、ワーク１はＶブロック２に載せられる。このとき、ワーク１における第１円筒部１１のみがＶブロック２に当接している。なお、Ｖブロックは本発明のワーク受け台に相当する。 As shown in FIGS. 1 and 2, a workpiece 1 that is an object to be measured is disposed between a cylindrical first cylindrical portion 11, a cylindrical second cylindrical portion 12, and both cylindrical portions 11 and 12. The separator 1 is provided and they are integrated by welding or the like. In the measurement, the workpiece 1 is placed on the V block 2. At this time, only the first cylindrical portion 11 of the workpiece 1 is in contact with the V block 2. The V block corresponds to the work cradle of the present invention.

回転機構３は、電動機（図示せず）等が内蔵された駆動部３１と、駆動部３１により回転されるシャフト３２とを備えている。そして、シャフト３２がワーク１における第１円筒部１１の端面に係合された状態で、駆動部３１によりシャフト３２を介してワーク１を回転させるようになっている。より詳細には、回転機構３は、ワーク１を所定の回転位置に順に回転させるものである。   The rotation mechanism 3 includes a drive unit 31 in which an electric motor (not shown) or the like is incorporated, and a shaft 32 rotated by the drive unit 31. The workpiece 1 is rotated by the drive unit 31 via the shaft 32 in a state where the shaft 32 is engaged with the end surface of the first cylindrical portion 11 of the workpiece 1. More specifically, the rotation mechanism 3 rotates the workpiece 1 in order to a predetermined rotation position.

第１測定機構４は、第１円筒部１１における外周面に接してその接触部位の径方向位置を測定する２個の第１センサ４１と、第２円筒部１２における外周面に接してその接触部位の径方向位置を測定する１個の第２センサ４２とを備えている。因みに、２個の第１センサ４１は、ワーク１の軸方向にずらして配置されている。   The first measurement mechanism 4 is in contact with the outer peripheral surface of the first cylindrical portion 11 and two first sensors 41 that measure the radial position of the contact portion, and the outer peripheral surface of the second cylindrical portion 12 is in contact therewith. And a second sensor 42 for measuring the radial position of the part. Incidentally, the two first sensors 41 are arranged so as to be shifted in the axial direction of the workpiece 1.

プレート４３には、これらのセンサ４１、４２が装着されるとともに、ワーク１をＶブロック２に押し付けてワーク１のガタ付きを防止するワーク押え４４が装着されている。ワーク押え４４は、ワーク１の外形寸法のばらつきに追従できるように、プレート４３に対して相対的に移動可能になっているとともに、ばねによってワーク１側に付勢されている。   These sensors 41 and 42 are mounted on the plate 43, and a work presser 44 that presses the work 1 against the V block 2 to prevent the work 1 from rattling is mounted. The work retainer 44 is movable relative to the plate 43 so as to follow variations in the external dimensions of the work 1 and is biased toward the work 1 by a spring.

そして、エアシリンダ（図示せず）等が内蔵された駆動部４５によりプレート４３を天地方向に往復動させるようになっている。また、プレート４３をワーク１に向かって移動させた際、プレート４３が図示しないストッパに当接することにより、プレート４３の停止位置が決定されるようになっている。   The plate 43 is reciprocated in the vertical direction by a drive unit 45 having an air cylinder (not shown) or the like built therein. Further, when the plate 43 is moved toward the workpiece 1, the stop position of the plate 43 is determined by the plate 43 coming into contact with a stopper (not shown).

第２測定機構５は、第２円筒部１２における端面に接してその接触部位の軸方向位置を測定する４個の第３センサ５１を備えている。第３センサ５１は、９０度間隔でプレート５２に装着されている。そして、エアシリンダ（図示せず）等が内蔵された駆動部５３によりプレート５２をワーク１の軸方向に往復動させるようになっている。また、プレート５２をワーク１に向かって移動させた際、プレート５２が図示しないストッパに当接することにより、プレート５２の停止位置が決定されるようになっている。   The second measurement mechanism 5 includes four third sensors 51 that are in contact with the end surface of the second cylindrical portion 12 and measure the axial position of the contact portion. The third sensor 51 is attached to the plate 52 at intervals of 90 degrees. The plate 52 is reciprocated in the axial direction of the workpiece 1 by a drive unit 53 in which an air cylinder (not shown) or the like is incorporated. Further, when the plate 52 is moved toward the work 1, the stop position of the plate 52 is determined by the plate 52 coming into contact with a stopper (not shown).

マイコンやメモリー等を有するデータ処理装置６には、回転機構３からの回転位置データ、および第１〜第３センサ４１、４２、５１の測定データが入力されるようになっている。そして、データ処理装置６は、それらのデータに基づいて、第１円筒部１１と第２円筒部１２の同軸度を演算するとともに、ワーク１の軸に対する第２円筒部１２の直角度を演算する。なお、データ処理装置６は、本発明の演算手段に相当する。   The data processing device 6 having a microcomputer, a memory, and the like receives the rotational position data from the rotation mechanism 3 and the measurement data of the first to third sensors 41, 42, 51. Then, the data processing device 6 calculates the coaxiality of the first cylindrical portion 11 and the second cylindrical portion 12 based on those data, and calculates the squareness of the second cylindrical portion 12 with respect to the axis of the workpiece 1. . The data processing device 6 corresponds to the calculation means of the present invention.

次に、同軸度の測定方法について説明する。   Next, a method for measuring the coaxiality will be described.

本実施形態では、回転機構３によりワーク１を９０度ずつ回転させて、第１センサ４１、第２センサ４２により４回測定を行う。このように、ワーク１を回転させて測定を行うことにより、１断面の中心を求めるために必要なデータを１個のセンサで得られるようにしている。   In the present embodiment, the workpiece 1 is rotated by 90 degrees by the rotation mechanism 3, and measurement is performed four times by the first sensor 41 and the second sensor 42. Thus, by rotating the workpiece 1 and performing the measurement, data necessary for obtaining the center of one cross section can be obtained with one sensor.

第１センサ４１、第２センサ４２による１回目の測定を行うために、ワーク１をＶブロック２に載せ、第１測定機構４のプレート４３を下降させてプレート４３をストッパに当接させる。これにより、ワーク押え４４が第１円筒部１１に当接し、ワーク押え４４によりワーク１がＶブロック２に押し付けられ、ワーク１が固定される。   In order to perform the first measurement by the first sensor 41 and the second sensor 42, the work 1 is placed on the V block 2, the plate 43 of the first measurement mechanism 4 is lowered, and the plate 43 is brought into contact with the stopper. As a result, the work presser 44 comes into contact with the first cylindrical portion 11, the work presser 44 presses the work 1 against the V block 2, and the work 1 is fixed.

この状態で、第１センサ４１は、第１円筒部１１の外周面に接してその接触部位の径方向位置を測定し、その測定データをデータ処理装置６に出力する。また、第２センサ４２は、第２円筒部１２の外周面に接してその接触部位の径方向位置を測定し、その測定データをデータ処理装置６に出力する。そして、データ処理装置６は、今回入力された１回目の測定データをメモリーに記憶させる。   In this state, the first sensor 41 is in contact with the outer peripheral surface of the first cylindrical portion 11, measures the radial position of the contact portion, and outputs the measurement data to the data processing device 6. Further, the second sensor 42 is in contact with the outer peripheral surface of the second cylindrical portion 12, measures the radial position of the contact portion, and outputs the measurement data to the data processing device 6. The data processing device 6 stores the first measurement data input this time in the memory.

次に、２回目の測定を行う。第１測定機構４のプレート４３を上昇させて、第１センサ４１、第２センサ４２、およびワーク押え４４を、ワーク１から離す。この後、ワーク受け台２にワーク１を載せた状態で、回転機構３によりワーク１を９０度回転させる。次いで、第１測定機構４のプレート４３を下降させてプレート４３をストッパに当接させる。この状態で、第１センサ４１は、第１円筒部１１の外周面に接してその接触部位の径方向位置を測定し、その測定データをデータ処理装置６に出力する。また、第２センサ４２は、第２円筒部１２の外周面に接してその接触部位の径方向位置を測定し、その測定データをデータ処理装置６に出力する。そして、データ処理装置６は、今回入力された２回目の測定データをメモリーに記憶させる。   Next, the second measurement is performed. The plate 43 of the first measurement mechanism 4 is raised, and the first sensor 41, the second sensor 42, and the work holder 44 are separated from the work 1. Thereafter, the work 1 is rotated 90 degrees by the rotation mechanism 3 while the work 1 is placed on the work cradle 2. Next, the plate 43 of the first measurement mechanism 4 is lowered to bring the plate 43 into contact with the stopper. In this state, the first sensor 41 is in contact with the outer peripheral surface of the first cylindrical portion 11, measures the radial position of the contact portion, and outputs the measurement data to the data processing device 6. Further, the second sensor 42 is in contact with the outer peripheral surface of the second cylindrical portion 12, measures the radial position of the contact portion, and outputs the measurement data to the data processing device 6. The data processing device 6 stores the second measurement data input this time in the memory.

次に、２回目の測定と同様にして、３回目および４回目の測定を行う。   Next, the third and fourth measurements are performed in the same manner as the second measurement.

次に、データ処理装置６は、メモリーに記憶させた測定データに基づいて同軸度を演算する。より詳細には、２個の第１センサ４１の測定データに基づいて第１円筒部１１の軸を演算により求め、第２センサ４２の測定データに基づいて第２円筒部１２の中心を演算により求め、さらにそれらの演算結果に基づいて第１円筒部１１と第２円筒部１２の同軸度を演算により求める。   Next, the data processing device 6 calculates the coaxiality based on the measurement data stored in the memory. More specifically, the axis of the first cylindrical portion 11 is obtained by calculation based on the measurement data of the two first sensors 41, and the center of the second cylindrical portion 12 is calculated by calculation based on the measurement data of the second sensor 42. Further, the coaxiality of the first cylindrical portion 11 and the second cylindrical portion 12 is obtained by calculation based on the calculation results.

次に、直角度の測定方法について説明する。   Next, a method for measuring perpendicularity will be described.

まず、ワーク押え４４によりワーク１がＶブロック２に固定されている状態で、第２測定機構５のプレート５２をワーク１に向かって移動させてプレート５２をストッパに当接させる。４個の第３センサ５１は、第２円筒部１２の端面に接してその接触部位の軸方向位置を測定し、その測定データをデータ処理装置６に出力する。   First, in a state where the workpiece 1 is fixed to the V block 2 by the workpiece presser 44, the plate 52 of the second measuring mechanism 5 is moved toward the workpiece 1 to bring the plate 52 into contact with the stopper. The four third sensors 51 are in contact with the end surface of the second cylindrical portion 12, measure the axial position of the contact portion, and output the measurement data to the data processing device 6.

そして、データ処理装置６は、第１センサ４１の測定データに基づいて求めた第１円筒部１１の軸に対する第２円筒部１２の直角度を、第３センサ５１の測定データに基づいて演算する。   Then, the data processing device 6 calculates the squareness of the second cylindrical portion 12 with respect to the axis of the first cylindrical portion 11 obtained based on the measurement data of the first sensor 41 based on the measurement data of the third sensor 51. .

以上述べた本実施形態によると、第１円筒部１１を測定する第１センサ４１と第２円筒部１２を測定する第２センサ４２とを備えているため、第１円筒部１１と第２円筒部１２を同時に測定することができ、したがって、短時間で同軸度を測定することができる。また、測定時間が短くなると、測定装置の台数を少なくできるため、設備費を低減することができる。   According to the present embodiment described above, since the first sensor 41 for measuring the first cylindrical portion 11 and the second sensor 42 for measuring the second cylindrical portion 12 are provided, the first cylindrical portion 11 and the second cylinder are provided. The parts 12 can be measured at the same time, and therefore the coaxiality can be measured in a short time. Further, when the measurement time is shortened, the number of measuring devices can be reduced, so that the equipment cost can be reduced.

また、ワーク１を所定の回転位置に順に回転させるため、円筒部１１、１２の周方向に沿って多数のセンサを配置する必要がなく、したがって、センサ数を少なくすることができる。   Further, since the workpiece 1 is sequentially rotated to a predetermined rotational position, there is no need to arrange a large number of sensors along the circumferential direction of the cylindrical portions 11 and 12, and therefore the number of sensors can be reduced.

なお、本実施形態では、第１センサ４１、第２センサ４２により４回測定を行ったが、１２０度間隔の３個所の回転位置にワーク１を順に回転させて、第１センサ４１、第２センサ４２により３回測定を行うようにしてもよい。   In the present embodiment, the measurement is performed four times by the first sensor 41 and the second sensor 42. However, the work 1 is sequentially rotated to three rotational positions at intervals of 120 degrees, and the first sensor 41 and the second sensor 42 are rotated. You may make it perform a measurement 3 times with the sensor 42. FIG.

（第２実施形態）
本発明の第２実施形態について説明する。図３は第２実施形態に係る同軸度測定装置の構成を模式的に示す正面図、図４は図３の装置の要部の側面図である。第１実施形態と同一もしくは均等部分には同一の符号を付し、その説明を省略する。 (Second Embodiment)
A second embodiment of the present invention will be described. FIG. 3 is a front view schematically showing the configuration of the coaxiality measuring apparatus according to the second embodiment, and FIG. 4 is a side view of the main part of the apparatus of FIG. The same or equivalent parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

本実施形態は、第１測定機構４を３個備え（図４参照）、回転機構３を廃止している（図３参照）。図４に示すように、第１測定機構４は、Ｖブロック２側を除いて、ワーク１の周方向に沿って９０度間隔で配置されている。   In the present embodiment, three first measuring mechanisms 4 are provided (see FIG. 4), and the rotating mechanism 3 is eliminated (see FIG. 3). As shown in FIG. 4, the first measurement mechanisms 4 are arranged at intervals of 90 degrees along the circumferential direction of the workpiece 1 except for the V block 2 side.

本実施形態では、各センサ４１、４２、５１による測定を１回行う。すなわち、ワーク１をＶブロック２に載せ、３個の第１測定機構４のプレート４３をワーク１に向かって移動させてプレート４３をストッパに当接させるとともに、第２測定機構５のプレート５２をワーク１に向かって移動させてプレート５２をストッパに当接させる。   In this embodiment, the measurement by each sensor 41, 42, 51 is performed once. That is, the work 1 is placed on the V block 2 and the three plates 43 of the first measurement mechanism 4 are moved toward the work 1 to bring the plates 43 into contact with the stoppers, and the plate 52 of the second measurement mechanism 5 is moved. The plate 52 is brought into contact with the stopper by moving toward the work 1.

この状態で、６個の第１センサ４１は、第１円筒部１１の外周面に接してその接触部位の径方向位置を測定し、その測定データをデータ処理装置６に出力する。また、３個の第２センサ４２は、第２円筒部１２の外周面に接してその接触部位の径方向位置を測定し、その測定データをデータ処理装置６に出力する。さらに、４個の第３センサ５１は、第２円筒部１２の端面に接してその接触部位の軸方向位置を測定し、その測定データをデータ処理装置６に出力する。そして、データ処理装置６は、それらの測定データに基づいて、同軸度および直角度を演算する。   In this state, the six first sensors 41 are in contact with the outer peripheral surface of the first cylindrical portion 11, measure the radial positions of the contact portions, and output the measurement data to the data processing device 6. Further, the three second sensors 42 are in contact with the outer peripheral surface of the second cylindrical portion 12, measure the radial positions of the contact portions, and output the measurement data to the data processing device 6. Further, the four third sensors 51 are in contact with the end surface of the second cylindrical portion 12, measure the axial position of the contact portion, and output the measurement data to the data processing device 6. And the data processor 6 calculates a coaxiality and a squareness based on those measurement data.

これによると、同軸度を測定するために必要なデータを同時に得ることができるため、極めて短時間で同軸度を測定することができる。   According to this, since data necessary for measuring the coaxiality can be obtained at the same time, the coaxiality can be measured in an extremely short time.
