Description

本発明は、検出器支持装置に関するもので、特に真円度測定機などに用いられワークの微小変位を検出する検出器を支持する検出器支持装置に関する。   The present invention relates to a detector support device, and more particularly to a detector support device that supports a detector that is used in a roundness measuring machine or the like and detects a minute displacement of a workpiece.

円筒形状のワークはその軸心を中心に回転され、真円度や円筒度等が測定される。例えば図２１に示すような鍔付のワークの場合は、ワークＷを回転中心線ＷＣの回りに回転させ、レバー式等の検出器３１の接触子Ｐを円筒外周部に当接させて外周部の振れを検出し外周部の真円度を測定する。あるいは検出器３１の接触子Ｐを孔の内周部に当接させて孔の真円度を測定し、また接触子Ｐを鍔部上面に当接させて鍔部の振れを検出する。   The cylindrical workpiece is rotated around its axis, and roundness, cylindricity, and the like are measured. For example, in the case of a work with a flange as shown in FIG. 21, the work W is rotated around the rotation center line WC, and the contact P of the detector 31 such as a lever type is brought into contact with the outer peripheral part of the cylinder. The roundness of the outer peripheral portion is measured by detecting the vibration of the outer periphery. Alternatively, the roundness of the hole is measured by bringing the contact P of the detector 31 into contact with the inner peripheral portion of the hole, and the deflection of the hook is detected by bringing the contact P into contact with the upper surface of the hook.

この場合、例えば検出器３１の姿勢を垂直に支持し検出方向を水平方向にした状態で円筒外周部の振れを検出し、次に検出器３１の姿勢を水平に支持替えするとともに、検出方向を垂直方向に調整して鍔部の振れを検出する必要がある。   In this case, for example, the vibration of the outer periphery of the cylinder is detected in a state where the posture of the detector 31 is vertically supported and the detection direction is horizontal, and then the posture of the detector 31 is horizontally supported and the detection direction is changed. It is necessary to detect the shake of the buttocks by adjusting in the vertical direction.

このため、検出器３１の検出方向切換えを容易に可能にすべく、種々の検出器支持装置が提案され、そのような検出器支持装置を備えた真円度測定機も提案されている（例えば、特許文献１、及び特許文献２参照。）。   For this reason, various detector support devices have been proposed in order to easily switch the detection direction of the detector 31, and a roundness measuring machine including such a detector support device has also been proposed (for example, , Patent Document 1 and Patent Document 2).

特許文献１に記載された検出器支持装置は、図２２及び図２３に示すようなものである。即ちＬ字状の支持アーム１１１の一端が水平垂直微調機構２２を介して保持台に回転可能に取り付けられ、他端には検出器３１が固定されている。検出器３１を垂直に支持した状態（図２２）から支持アーム１１１を９０°回転させ、図２３に示すように、検出器３１の姿勢を水平方向に切換えるようになっている。   The detector support apparatus described in Patent Document 1 is as shown in FIGS. 22 and 23. That is, one end of the L-shaped support arm 111 is rotatably attached to the holding table via the horizontal / vertical fine adjustment mechanism 22, and the detector 31 is fixed to the other end. The support arm 111 is rotated 90 ° from the state in which the detector 31 is vertically supported (FIG. 22), and the posture of the detector 31 is switched in the horizontal direction as shown in FIG.

この場合、支持アーム１１１を９０°回転させて検出器３１の姿勢を水平に切換えても、検出方向は水平方向のままであるので、検出方向を垂直方向に切換えるために、検出器３１を検出器の軸心の回りに９０°回転させる。   In this case, even if the support arm 111 is rotated by 90 ° and the posture of the detector 31 is switched to the horizontal direction, the detection direction remains horizontal, so the detector 31 is detected to switch the detection direction to the vertical direction. Rotate 90 ° around the vessel axis.

また、特許文献２に記載された検出器支持装置は、図２４に示すような構造になっている。即ち、保持台２１に固定された第１のアーム３１１の他端には、垂直方向に対して保持台２１の移動軸ＨＣ側に４５°傾斜した回転軸心ＲＣが設けられ、検出器３１を支持した第２のアーム３１２が回転軸心ＲＣの回りに回転可能に構成されている。   Moreover, the detector support apparatus described in Patent Document 2 has a structure as shown in FIG. That is, the other end of the first arm 311 fixed to the holding table 21 is provided with a rotation axis RC inclined at 45 ° to the moving axis HC side of the holding table 21 with respect to the vertical direction. The supported second arm 312 is configured to be rotatable around the rotation axis RC.

図２４（ａ）に示すように、水平姿勢で支持された検出器３１のレバー３１ａが検出器本体に対して９０°折り曲げられ、先端の接触子ＰでワークＷの外周部の振れを検出する。第２のアーム３１２を１８０°回転させると図２４（ｂ）に示すように、ワークＷの鍔部の上面の振れを検出することができる。この場合は検出器３１を軸心ＫＣの回りに回転させる必要がない。
特開Ｈ１１−０６３９７１号公報 特開Ｈ０６−３００５０５号公報 As shown in FIG. 24A, the lever 31a of the detector 31 supported in a horizontal posture is bent by 90 ° with respect to the detector body, and the deflection at the outer peripheral portion of the workpiece W is detected by the contact P at the tip. . When the second arm 312 is rotated by 180 °, as shown in FIG. In this case, it is not necessary to rotate the detector 31 around the axis KC.
JP H11-063971 JP H06-300505 A

しかし、前述の特許文献１（特開Ｈ１１−０６３９７１号公報）の検出器支持装置の場合、検出器３１が垂直姿勢のときに接触子の位置が支持アーム１１１の下端よりも上にあるため、大径ワークの中央部の孔を測定する場合にワークの外周部が支持アーム１１１の下端と干渉するという問題があった。   However, in the case of the detector support device of the above-mentioned Patent Document 1 (Japanese Patent Laid-Open No. H11-063971), the position of the contactor is above the lower end of the support arm 111 when the detector 31 is in the vertical posture. When measuring the hole at the center of the large-diameter workpiece, there is a problem that the outer peripheral portion of the workpiece interferes with the lower end of the support arm 111.

また、前述の特許文献２（特開Ｈ０６−３００５０５号公報）に記載された検出器支持装置も、前述の特許文献１の検出器支持装置同様であり、懐が狭いので、大径ワークの中央部の孔を測定する場合に問題があった。また、検出方向を垂直方向とした時に、保持台２１の移動軸ＨＣと直交する方向から検出器３１のレバー３１ａを付き出すことができず、種々の測定対象に対して対応幅が狭いという問題も有していた。   Further, the detector support device described in the above-mentioned Patent Document 2 (Japanese Patent Laid-Open No. H06-300505) is also similar to the detector support device of the above-mentioned Patent Document 1, and has a narrow pocket. There was a problem when measuring the holes in the part. Further, when the detection direction is the vertical direction, the lever 31a of the detector 31 cannot be attached from the direction orthogonal to the movement axis HC of the holding base 21, and the corresponding range is narrow for various measurement objects. Also had.

前述の特許文献１及び特許文献２の検出器支持装置の場合に、検出器３１の取付位置を下げるかあるいは軸方向に長いレバーを有する検出器３１を用いることによって、接触子の位置を保持台よりも下方に下げることができるが、このようにすると、検出器３１の姿勢切換え前後で接触子の位置が大きくずれ、そのために検出器支持装置を水平方向及び垂直方向に大きく移動させなければならない。   In the case of the detector support devices of Patent Document 1 and Patent Document 2 described above, the position of the contact is held by lowering the mounting position of the detector 31 or using the detector 31 having a long lever in the axial direction. However, in this case, the position of the contactor greatly deviates before and after the attitude change of the detector 31, and therefore the detector support device must be moved largely in the horizontal and vertical directions. .

本発明はこのような事情に鑑みてなされたもので、種々のワークに対して検出器の検出方向を簡単に切換えでき、円筒外周面、内周面及び平面の測定を容易に行うことのできる検出器支持装置を提供することを目的とする。   The present invention has been made in view of such circumstances, and can easily switch the detection direction of the detector with respect to various workpieces, and can easily measure the cylindrical outer peripheral surface, inner peripheral surface and plane. It is an object to provide a detector support device.

以下添付図面に従って本発明に係る検出器支持装置の好ましい実施の形態について詳説する。尚、各図において同一部材には同一の番号または記号を付している。   Hereinafter, a preferred embodiment of a detector support device according to the present invention will be described in detail with reference to the accompanying drawings. In each figure, the same number or symbol is attached to the same member.

本発明に係る検出器支持装置は、円筒形状のワークの真円度や円筒度等を測定する真円度測定機等に好適に用いられるが、最初にこの真円度測定機についてその概要を説明する。   The detector support device according to the present invention is preferably used for a roundness measuring machine for measuring the roundness, cylindricity, etc. of a cylindrical workpiece. First, an outline of this roundness measuring machine will be described. explain.

図１は、真円度測定機の外観を表わす正面図である。真円度測定機２０は、ベース２６、ワークＷを載置して回転中心線ＷＣの回りに高精度で回転する回転テーブル２５、ベース２６上に立設されたコラム２４、コラム２４に沿って図のＺ方向に上下移動する上下移動台２３、上下移動台２３に取り付けられ回転中心線ＷＣに向かった移動軸ＨＣに沿って図のＸ方向に水平移動する保持台２１、及び図示しない管制部等からなっている。   FIG. 1 is a front view showing an appearance of a roundness measuring machine. The roundness measuring machine 20 is arranged along a base 26, a rotary table 25 on which a work W is placed and rotated with high accuracy around a rotation center line WC, a column 24 erected on the base 26, and the column 24. A vertical movement base 23 that moves up and down in the Z direction in the figure, a holding base 21 that is attached to the vertical movement stage 23 and moves horizontally in the X direction along the movement axis HC toward the rotation center line WC, and a control unit (not shown) Etc.

保持台２１には、検出器支持装置１０を介して検出器３１が取り付けられている。検出器３１は、差動変圧器を組込んだレバー式検出器等が用いられる。なお、検出器３１はこれに限らず、デジタルスケールを用いたものや、光干渉式の検出器等が用いられてもよい。   A detector 31 is attached to the holding table 21 via the detector support device 10. As the detector 31, a lever type detector incorporating a differential transformer is used. The detector 31 is not limited to this, and a detector using a digital scale, an optical interference detector, or the like may be used.

円筒形状のワークＷの真円度を測定する場合は、図１に示すように、先ずワークＷを回転テーブル２５上に載置する。この時、ワークＷの軸心と回転中心線ＷＣとがほぼ一致するように載置位置を調整する。   When measuring the roundness of the cylindrical workpiece W, the workpiece W is first placed on the rotary table 25 as shown in FIG. At this time, the mounting position is adjusted so that the axis of the workpiece W and the rotation center line WC substantially coincide with each other.

この載置位置の調整は、検出器支持装置１０を介して検出器３１を保持した保持台２１を移動軸ＨＣに沿ってワークＷ方向に移動させ、検出器３１の接触子ＰをワークＷの外周面に当接させ、回転テーブル２５を回転させながら低倍率でワークＷの振れを見て、振れが小さくなるように載置位置を調整する。この場合、ワークＷの軸心と回転中心線ＷＣとが完全一致しなくても、測定値を解析する段階で偏心補正ソフトを用いてデータを補正することができる。   The placement position is adjusted by moving the holder 21 holding the detector 31 via the detector support device 10 in the direction of the workpiece W along the movement axis HC, and moving the contact P of the detector 31 to the workpiece W. The placement position is adjusted so that the shake is reduced by contacting the outer peripheral surface and watching the shake of the work W at a low magnification while rotating the rotary table 25. In this case, even if the axis of the workpiece W and the rotation center line WC do not completely coincide with each other, the data can be corrected using the eccentricity correction software at the stage of analyzing the measurement value.

次に、測定倍率を高倍率に切換えて、ワークＷの１回転分のデータを取り込む。このデータを管制部で解析し、ワークＷの外周部の真円度を算出する。算出結果は管制部に設けられた表示部に表示するとともに、必要に応じ付属のプリンタ等で記録する。   Next, the measurement magnification is switched to a high magnification, and data for one rotation of the workpiece W is captured. This data is analyzed by the control unit, and the roundness of the outer peripheral portion of the workpiece W is calculated. The calculation result is displayed on a display unit provided in the control unit, and is recorded by an attached printer or the like as necessary.

ワークＷが前出の図２１に示すような鍔付の場合、鍔の面の振れが測定される。この場合は、検出器３１の姿勢を切換えて、検出方向を垂直方向に切換える。この検出器３１の姿勢切換えは、検出器支持装置１０で行う。   When the workpiece W is tacked as shown in FIG. 21, the runout of the heel surface is measured. In this case, the orientation of the detector 31 is switched to switch the detection direction to the vertical direction. The posture switching of the detector 31 is performed by the detector support device 10.

When the distance between the relative movement direction and the straight line L2 in the same direction (that is, the axis of the support shaft 14) L2 is D, the distance A and the distance C are the same distance, and the distance B and the distance D are the same distance. It is configured.

また、本実施の形態では、距離Ａと距離Ｂとが同一距離になるように形成されている。ただし、距離Ａと距離Ｂとは必ずしも同一距離に形成される必要はない。距離Ｂが距離Ａより長くてもよく、距離Ｂが距離Ａより短くてもよい。   In the present embodiment, the distance A and the distance B are formed to be the same distance. However, the distance A and the distance B are not necessarily formed at the same distance. The distance B may be longer than the distance A, and the distance B may be shorter than the distance A.

図２及び図４に示すように、垂直姿勢で支持された検出器３１の接触子（検出点）Ｐは、支持軸１４の軸線である直線Ｌ２から距離Ｄだけ下方に配置されている。このため、測定に当たって保持台２１がワークＷと干渉することがない。   As shown in FIGS. 2 and 4, the contact (detection point) P of the detector 31 supported in the vertical posture is disposed below the straight line L <b> 2 that is the axis of the support shaft 14 by a distance D. For this reason, the holding table 21 does not interfere with the workpiece W during measurement.

このように垂直姿勢で支持された検出器３１に対し、常に垂直姿勢のみでは測定できない箇所が生ずる。例えば図２１に示すようなワークＷの鍔部の振れを検出する場合は、検出器３１の姿勢を水平姿勢に切り替える必要がある。   As described above, there are places where the detector 31 supported in the vertical posture cannot always be measured only in the vertical posture. For example, when detecting the wobbling of the buttocks of the workpiece W as shown in FIG. 21, it is necessary to switch the posture of the detector 31 to the horizontal posture.

本発明に係る検出器支持装置１０では、検出器３１の姿勢を垂直姿勢から水平姿勢に切り替える場合、図７に示すように、第１のアーム１１を左側面からみて反時計方向に９０°回転させるとともに、第２のアーム１２を左側面からみて時計方向に９０°回転させ、更に第３のアーム１３を左側面からみて反時計方向に９０°回転させる。これにより図５の正面図、図６の平面図、及び図７の左側面図に示すように、検出器３１が水平姿勢で支持された状態となる。   In the detector support device 10 according to the present invention, when the posture of the detector 31 is switched from the vertical posture to the horizontal posture, as shown in FIG. 7, the first arm 11 is rotated 90 ° counterclockwise when viewed from the left side. At the same time, the second arm 12 is rotated 90 ° clockwise as viewed from the left side, and the third arm 13 is further rotated 90 ° counterclockwise as viewed from the left side. Accordingly, as shown in the front view of FIG. 5, the plan view of FIG. 6, and the left side view of FIG. 7, the detector 31 is supported in a horizontal posture.

この場合も図６及び図７に示すように、水平姿勢で支持された検出器３１の接触子（検出点）Ｐは、支持軸１４の軸線である直線Ｌ２から距離Ｄだけ下方に配置されている。このため、測定に当たって保持台２１がワークＷと干渉することがない。なお、検出器３１の検出方向を変更する場合は、検出器３１を取り付け軸３１Ａの周りに回転させればよい。   Also in this case, as shown in FIGS. 6 and 7, the contact (detection point) P of the detector 31 supported in the horizontal posture is disposed below the straight line L2 that is the axis of the support shaft 14 by a distance D. Yes. For this reason, the holding table 21 does not interfere with the workpiece W during measurement. In addition, what is necessary is just to rotate the detector 31 around the attachment axis | shaft 31A, when changing the detection direction of the detector 31. FIG.

本発明の検出器支持装置１０は、前述した距離Ａと距離Ｃとが等しく且つ距離Ｄと距離Ｂとが等しいので、図４及び図７からも明らかなように、検出器３１の姿勢が垂直姿勢と水平姿勢のどちらの姿勢においても、先端子（検出点）Ｐの位置が図２に示す直線Ｌ２を含む垂直平面上で直線Ｌ２から距離Ｄだけ下方に位置している。即ち、検出器３１の姿勢を垂直姿勢から水平姿勢にあるいは水平姿勢から垂直姿勢に切り替えても、先端子（検出点）Ｐの位置が変化しない。また、先端子（検出点）Ｐの位置が図２に示す直線Ｌ２から距離Ｄだけ下方に位置づけられているので、測定の際に保持台２１がワークＷと干渉することがない。   In the detector support device 10 of the present invention, since the distance A and the distance C are equal and the distance D and the distance B are equal, the posture of the detector 31 is vertical as apparent from FIGS. 4 and 7. In both the posture and the horizontal posture, the position of the leading terminal (detection point) P is positioned below the straight line L2 by a distance D on the vertical plane including the straight line L2 shown in FIG. That is, even if the posture of the detector 31 is switched from the vertical posture to the horizontal posture or from the horizontal posture to the vertical posture, the position of the leading terminal (detection point) P does not change. Further, since the position of the leading terminal (detection point) P is positioned below the straight line L2 shown in FIG. 2 by a distance D, the holding base 21 does not interfere with the workpiece W during measurement.

図８は、検出器３１を垂直姿勢から４５°傾斜させて支持した状態を示す左側面図である。このときは図８に示すように、第１のアーム１１を左側面からみて反時計方向に４５°回転させるとともに、第２のアーム１２を左側面からみて時計方向に４５°回転させ、更に第３のアーム１３を左側面からみて反時計方向に４５°回転させる。なお、傾斜角度は４５°に限らず、任意の傾斜姿勢とすることができる。   FIG. 8 is a left side view showing a state in which the detector 31 is supported by being inclined by 45 ° from the vertical posture. At this time, as shown in FIG. 8, the first arm 11 is rotated 45 ° counterclockwise when viewed from the left side, and the second arm 12 is rotated 45 ° clockwise when viewed from the left side. 3 arm 13 is rotated 45 ° counterclockwise as seen from the left side. Note that the inclination angle is not limited to 45 °, and an arbitrary inclination posture can be adopted.

この場合も、先端子（検出点）Ｐの位置を変化させずに、先端子（検出点）Ｐの位置が図２に示す直線Ｌ２から距離Ｄだけ下方に位置づけられた状態を維持させたまま、検出器３１を任意の傾斜姿勢で支持することができる。   Also in this case, without changing the position of the leading terminal (detection point) P, the position of the leading terminal (detection point) P is maintained below the straight line L2 shown in FIG. The detector 31 can be supported in an arbitrary inclined posture.

次に、本発明の第２の実施形態について説明する。図９乃至図１４は本発明に係る検出器支持装置の第２の実施形態を表したものである。図９乃至図１１は検出器３１を垂直姿勢で支持した状態を表しており、図９は正面図、図１０は平面図、図１１は左側面図である。また、図１２乃至図１４は検出器３１を水平姿勢で支持した状態を表しており、図１２は正面図、図１３は平面図、図１４は左側面図である。   Next, a second embodiment of the present invention will be described. 9 to 14 show a second embodiment of the detector support device according to the present invention. 9 to 11 show a state in which the detector 31 is supported in a vertical posture. FIG. 9 is a front view, FIG. 10 is a plan view, and FIG. 11 is a left side view. 12 to 14 show a state in which the detector 31 is supported in a horizontal posture. FIG. 12 is a front view, FIG. 13 is a plan view, and FIG. 14 is a left side view.

この第２の実施形態で説明する検出器支持装置１０Ａは、前述の第１の実施形態で説明した検出器支持装置１０と大部分の構造は略同一である。そのため、検出器支持装置１０と共通する部分については説明を省略する。   The detector support device 10A described in the second embodiment has almost the same structure as the detector support device 10 described in the first embodiment. Therefore, description of the parts common to the detector support device 10 is omitted.

第１の実施形態で説明した検出器支持装置１０が３関節３アーム構造で構成されていたのに対して、この第２の実施形態の検出器支持装置１０Ａは、２関節３アーム構造となっている。具体的には、図１０に示すように、第１の支持部である支持軸１４、及び第２の支持部である支持軸１５は第１の実施形態の検出器支持装置１０同様、夫々支持する相手を回転可能に支持する支持部であるが、第３のアーム１３を支持する第２のアーム１２に形成された第３の支持部は固定支持部である。   The detector support device 10 described in the first embodiment has a three-joint three-arm structure, whereas the detector support device 10A of the second embodiment has a two-joint three-arm structure. ing. Specifically, as shown in FIG. 10, the support shaft 14 as the first support portion and the support shaft 15 as the second support portion are respectively supported in the same manner as the detector support device 10 of the first embodiment. The third support portion formed on the second arm 12 that supports the third arm 13 is a fixed support portion.

また、第１の実施形態で説明した距離Ａ、距離Ｂ、距離Ｃ、及び距離Ｄに関して、前述の第１の実施形態では距離Ａと距離Ｃとが同一距離であるとともに距離Ｂと距離Ｄとが同一距離であるが、距離Ａと距離Ｂとは必ずしも同一距離に形成される必要がなかった。   In addition, regarding the distance A, the distance B, the distance C, and the distance D described in the first embodiment, the distance A and the distance C are the same distance and the distance B and the distance D in the first embodiment described above. Are the same distance, but the distance A and the distance B are not necessarily formed at the same distance.

しかし、第２の実施形態の検出器支持装置１０Ａでは距離Ａと距離Ｂとが同一距離に形成されることが必須要件になっている。即ち、距離Ａ、距離Ｂ、距離Ｃ、及び距離Ｄが全て同一に形成されている。   However, in the detector support device 10A of the second embodiment, it is an essential requirement that the distance A and the distance B are formed at the same distance. That is, the distance A, the distance B, the distance C, and the distance D are all formed the same.

このように２関節３アームで構成された検出器支持装置１０Ａは、図９、図１０、及び図１１に示す状態で検出器３１を垂直姿勢で支持する。このとき、図９、図１１に示すように、検出器３１の接触子（検出点）Ｐは、支持軸１４の軸線である直線Ｌ２から距離Ｄだけ下方に配置されている。このため、測定に当たって保持台２１がワークＷと干渉することがない。   The detector support device 10A configured with two joints and three arms in this manner supports the detector 31 in a vertical posture in the state shown in FIGS. 9, 10, and 11. At this time, as shown in FIGS. 9 and 11, the contact (detection point) P of the detector 31 is arranged below the straight line L <b> 2 that is the axis of the support shaft 14 by a distance D. For this reason, the holding table 21 does not interfere with the workpiece W during measurement.

検出器支持装置１０Ａでは、検出器３１の姿勢を垂直姿勢から水平姿勢に切り替える場合、図１４に示すように、第１のアーム１１を左側面からみて反時計方向に１８０°回転させるとともに、第２のアーム１２を左側面からみて時計方向に９０°回転させる。これにより図１２の正面図、図１３の平面図、及び図１４の左側面図に示すように、検出器３１が水平姿勢で支持された状態となる。   In the detector support device 10A, when the posture of the detector 31 is switched from the vertical posture to the horizontal posture, as shown in FIG. The second arm 12 is rotated 90 ° clockwise as viewed from the left side. Accordingly, as shown in the front view of FIG. 12, the plan view of FIG. 13, and the left side view of FIG. 14, the detector 31 is supported in a horizontal posture.

この場合も図１２及び図１４に示すように、水平姿勢で支持された検出器３１の接触子（検出点）Ｐが、支持軸１４の軸線である直線Ｌ２から距離Ｄだけ下方に配置されている。このため、測定に当たって保持台２１がワークＷと干渉することがない。なお、検出器３１の検出方向を変更する場合は、検出器３１を取り付け軸３１Ａの周りに回転させればよい。   Also in this case, as shown in FIG. 12 and FIG. 14, the contact (detection point) P of the detector 31 supported in the horizontal posture is disposed below the straight line L2 that is the axis of the support shaft 14 by a distance D. Yes. For this reason, the holding table 21 does not interfere with the workpiece W during measurement. In addition, what is necessary is just to rotate the detector 31 around the attachment axis | shaft 31A, when changing the detection direction of the detector 31. FIG.

検出器支持装置１０Ａは、前述したように距離Ａ、距離Ｂ、距離Ｃ、及び距離Ｄが全て同一に形成されているので、図１１及び図１４からも明らかなように、検出器３１の姿勢が垂直姿勢と水平姿勢のどちらの姿勢においても、先端子（検出点）Ｐの位置が直線Ｌ２を含む垂直平面上で直線Ｌ２から距離Ｄだけ下方に位置している。即ち、検出器３１の姿勢を垂直姿勢から水平姿勢にあるいは水平姿勢から垂直姿勢に切り替えても、先端子（検出点）Ｐの位置が変化しない。また、先端子（検出点）Ｐの位置が直線Ｌ２から距離Ｄだけ下方に位置づけられているので、測定の際に保持台２１がワークＷと干渉することがない。   Since the detector support device 10A is formed with the same distance A, distance B, distance C, and distance D as described above, the posture of the detector 31 is apparent from FIGS. In both the vertical and horizontal attitudes, the position of the tip (detection point) P is positioned below the straight line L2 by a distance D on the vertical plane including the straight line L2. That is, even if the posture of the detector 31 is switched from the vertical posture to the horizontal posture or from the horizontal posture to the vertical posture, the position of the leading terminal (detection point) P does not change. Further, since the position of the leading terminal (detection point) P is positioned below the straight line L2 by the distance D, the holding base 21 does not interfere with the workpiece W during measurement.

なお、第１のアーム１１の回転範囲１８０°の両端、及び第２のアーム１２の回転範囲９０°の両端に夫々ストッパを設け、第１のアーム１１及び第２のアーム１２の回転範囲を夫々規制すればより操作し易く好適である。   It should be noted that stoppers are provided at both ends of the first arm 11 at a rotation range of 180 ° and at both ends of the rotation range of the second arm 12 at 90 °, respectively, so that the rotation ranges of the first arm 11 and the second arm 12 are respectively set. If restricted, it is easier to operate and is preferable.

次に、本発明の第３の実施形態について説明する。図１５乃至図２０は本発明に係る検出器支持装置の第３の実施形態を表したものである。図１５乃至図１７は検出器３１を垂直姿勢で支持した状態を表しており、図１５は正面図、図１６は平面図、図１７は左側面図である。また、図１８乃至図２０は検出器３１を水平姿勢で支持した状態を表しており、図１８は正面図、図１９は平面図、図２０は左側面図である。   Next, a third embodiment of the present invention will be described. 15 to 20 show a third embodiment of the detector support device according to the present invention. 15 to 17 show a state in which the detector 31 is supported in a vertical posture. FIG. 15 is a front view, FIG. 16 is a plan view, and FIG. 17 is a left side view. 18 to 20 show a state in which the detector 31 is supported in a horizontal posture. FIG. 18 is a front view, FIG. 19 is a plan view, and FIG. 20 is a left side view.

この第３の実施形態で説明する検出器支持装置１０Ｂも、前述の第１の実施形態で説明した検出器支持装置１０、及び第２の実施形態で説明した検出器支持装置１０Ａと大部分の構造は略同一である。そのため、検出器支持装置１０、１０Ａと共通する部分については説明を省略する。   The detector support device 10B described in the third embodiment is also mostly the detector support device 10 described in the first embodiment and the detector support device 10A described in the second embodiment. The structure is substantially the same. Therefore, description of the parts common to the detector support devices 10 and 10A is omitted.

第１の実施形態で説明した検出器支持装置１０が３関節３アーム構造で構成されていたのに対して、この第３の実施形態の検出器支持装置１０Ｂは、第２の実施形態の検出器支持装置１０Ａ同様に２関節３アーム構造となっている。具体的には、図１５、図１６に示すように、第１のアーム１１の一端を支持する第１の支持部が固定支持部で、第２の支持部である支持軸１５と第３の支持部である支持軸１６が夫々支持する相手を回転可能に支持する支持部である。   The detector support device 10 described in the first embodiment has a three-joint three-arm structure, whereas the detector support device 10B of the third embodiment has the detection of the second embodiment. Like the vessel support device 10A, it has a two-joint three-arm structure. Specifically, as shown in FIGS. 15 and 16, the first support portion that supports one end of the first arm 11 is a fixed support portion, and the support shaft 15 that is the second support portion and the third support portion. The support shaft 16 that is a support portion is a support portion that rotatably supports mating counterparts.

また、第１の実施形態で説明した距離Ａ、距離Ｂ、距離Ｃ、及び距離Ｄに関して、前述の第１の実施形態では距離Ａと距離Ｃとが同一距離であるとともに距離Ｂと距離Ｄとが同一距離であるが、距離Ａと距離Ｂとは必ずしも同一距離に形成される必要がなかった。   In addition, regarding the distance A, the distance B, the distance C, and the distance D described in the first embodiment, the distance A and the distance C are the same distance and the distance B and the distance D in the first embodiment described above. Are the same distance, but the distance A and the distance B are not necessarily formed at the same distance.

しかし、第３の実施形態の検出器支持装置１０Ｂでは第２の実施形態の検出器支持装置１０Ａ同様に、距離Ａと距離Ｂとが同一距離に形成されることが必須要件になっている。即ち、距離Ａ、距離Ｂ、距離Ｃ、及び距離Ｄが全て同一に形成されている。   However, in the detector support device 10B of the third embodiment, as in the detector support device 10A of the second embodiment, it is an essential requirement that the distance A and the distance B are formed at the same distance. That is, the distance A, the distance B, the distance C, and the distance D are all formed the same.

このような２関節３アームで構成された検出器支持装置１０Ｂは、図１５、図１６、及び図１７に示す状態で検出器３１を垂直姿勢で支持する。このとき、図１５、図１７に示すように、検出器３１の接触子（検出点）Ｐは、第１の支持部を通り保持台２１のワークＷに対する相対移動方向と同方向の直線Ｌ２から距離Ｄだけ下方に配置されている。このため、測定に当たって保持台２１がワークＷと干渉することがない。   The detector support device 10B configured by such two joints and three arms supports the detector 31 in a vertical posture in the state shown in FIGS. 15, 16, and 17. At this time, as shown in FIGS. 15 and 17, the contact (detection point) P of the detector 31 passes from the straight line L <b> 2 in the same direction as the relative movement direction of the holding base 21 with respect to the workpiece W through the first support portion. It is arranged below the distance D. For this reason, the holding table 21 does not interfere with the workpiece W during measurement.

検出器支持装置１０Ｂでは、検出器３１の姿勢を垂直姿勢から水平姿勢に切り替える場合、図２０に示すように、第２のアーム１２を左側面からみて時計方向に９０°回転させるとともに、第３のアーム１３を左側面からみて反時計方向に１８０°回転させる。これにより図１８の正面図、図１９の平面図、及び図２０の左側面図に示すように、検出器３１が水平姿勢で支持された状態となる。   In the detector support device 10B, when the posture of the detector 31 is switched from the vertical posture to the horizontal posture, as shown in FIG. The arm 13 is rotated 180 ° counterclockwise when viewed from the left side. Accordingly, as shown in the front view of FIG. 18, the plan view of FIG. 19, and the left side view of FIG. 20, the detector 31 is supported in a horizontal posture.

この場合も図１８及び図２０に示すように、水平姿勢で支持された検出器３１の接触子（検出点）Ｐが、前述の直線Ｌ２から距離Ｄだけ下方に配置されている。このため、測定に当たって保持台２１がワークＷと干渉することがない。なお、検出器３１の検出方向を変更する場合は、検出器３１を取り付け軸３１Ａの周りに回転させればよい。   Also in this case, as shown in FIGS. 18 and 20, the contact (detection point) P of the detector 31 supported in a horizontal posture is arranged below the straight line L2 by a distance D. For this reason, the holding table 21 does not interfere with the workpiece W during measurement. In addition, what is necessary is just to rotate the detector 31 around the attachment axis | shaft 31A, when changing the detection direction of the detector 31. FIG.

検出器支持装置１０Ｂは、前述したように距離Ａ、距離Ｂ、距離Ｃ、及び距離Ｄが全て同一に形成されているので、図１７及び図２０からも明らかなように、検出器３１の姿勢が垂直姿勢と水平姿勢のどちらの姿勢においても、先端子（検出点）Ｐの位置が直線Ｌ２を含む垂直平面上で直線Ｌ２から距離Ｄだけ下方に位置している。即ち、検出器３１の姿勢を垂直姿勢から水平姿勢にあるいは水平姿勢から垂直姿勢に切り替えても、先端子（検出点）Ｐの位置が変化しない。また、先端子（検出点）Ｐの位置が直線Ｌ２から距離Ｄだけ下方に位置づけられているので、測定の際に保持台２１がワークＷと干渉することがない。   Since the detector support device 10B is formed with the same distance A, distance B, distance C, and distance D as described above, the posture of the detector 31 is apparent from FIGS. In both the vertical and horizontal attitudes, the position of the tip (detection point) P is positioned below the straight line L2 by a distance D on the vertical plane including the straight line L2. That is, even if the posture of the detector 31 is switched from the vertical posture to the horizontal posture or from the horizontal posture to the vertical posture, the position of the leading terminal (detection point) P does not change. Further, since the position of the leading terminal (detection point) P is positioned below the straight line L2 by the distance D, the holding base 21 does not interfere with the workpiece W during measurement.

なお、第２のアーム１２の回転範囲９０°の両端、及び第３のアーム１３の回転範囲１８０°の両端に夫々ストッパを設け、第２のアーム１２及び第３のアーム１３の回転範囲を夫々規制すればより操作し易く好適である。   It should be noted that stoppers are provided at both ends of the second arm 12 at a rotation range of 90 ° and at both ends of the rotation range of the third arm 13 at 180 °, respectively, and the rotation ranges of the second arm 12 and the third arm 13 are respectively set. If it restricts, it is easy to operate and is suitable.

以上説明したように、本発明に係る検出器支持装置１０、１０Ａ、１０Ｂによれば、検出器３１の取り付け姿勢を垂直姿勢から水平姿勢に容易に切り替えることができ、また検出器３１の取り付け姿勢を切り替えても、保持台２１の下方に位置した検出器３１の接触子Ｐの位置を変化させることなく切り替えることができる。このため、ワークＷの内周面、外周面、鍔部の上面、下面等の各測定を迅速に行うことができる。   As described above, according to the detector support devices 10, 10A, and 10B according to the present invention, the mounting posture of the detector 31 can be easily switched from the vertical posture to the horizontal posture, and the mounting posture of the detector 31 is also possible. Can be switched without changing the position of the contact P of the detector 31 located below the holding table 21. For this reason, each measurement of the inner peripheral surface of the workpiece | work W, an outer peripheral surface, the upper surface of a collar part, a lower surface, etc. can be performed rapidly.

なお、前述した実施の形態において、本発明の検出器支持装置を用いた真円度測定機として、ワークＷが回転中心線ＷＣを中心に回転するワーク回転式真円度測定機２０で説明したが、本発明の検出器支持装置１０は、ワーク回転式真円度測定機２０に限らず、ワークＷが固定で検出器３１が回転中心線ＷＣの回りに回転する検出器回転式真円度測定機にも好適に用いることができ、また真円度測定機に限らずその他種々の測定装置にも効果的に用いることができる。   In the embodiment described above, the roundness measuring machine 20 using the detector support device of the present invention has been described with the workpiece rotating roundness measuring machine 20 in which the workpiece W rotates around the rotation center line WC. However, the detector support device 10 of the present invention is not limited to the workpiece rotation type roundness measuring machine 20, but a detector rotation type roundness in which the workpiece W is fixed and the detector 31 rotates around the rotation center line WC. It can be used suitably also for a measuring machine, and can be effectively used for various measuring devices as well as a roundness measuring machine.
