Description

本発明は、工作機械に取り付けられる工具ホルダの駆動軸に対するアングル軸および刃先方向の角度を測定するために用いられる測定治具及びそれを用いた角度測定方法に関する。   The present invention relates to an angle axis with respect to a drive axis of a tool holder attached to a machine tool and a measuring jig used for measuring an angle in a cutting edge direction and an angle measuring method using the same.

工作機械に取り付けられる工具ホルダとして、工作機械主軸に接続される駆動軸と、この駆動軸に対して角度が可変な状態で連動連結されたアングル軸とを有し、切削具をアングル軸に接続することで工作機械主軸に対して角度を変えて切削具を取り付けるアングルヘッドが知られている。   As a tool holder attached to a machine tool, it has a drive shaft connected to the machine tool main shaft and an angle shaft interlocked with the drive shaft in a variable angle state, and the cutting tool is connected to the angle shaft. An angle head for attaching a cutting tool by changing the angle with respect to the machine tool spindle is known.

このようなアングルヘッドでは、測定子をワークテーブル上に載置した状態でワークテーブルを互いに直交する２軸方向（例えば、X−Ｙ軸方向）に移動させアングル軸に取り付けられたテストバーに接触させることで、駆動軸に対するアングル軸の角度を測定する場合がある（下記特許文献１参照）。   With such an angle head, the work table is moved in two axial directions (for example, XY directions) orthogonal to each other while the measuring element is placed on the work table, and contacts a test bar attached to the angle shaft. By doing so, the angle of the angle shaft with respect to the drive shaft may be measured (see Patent Document 1 below).

しかしながら、従来のテストバーではアングル軸方向に延びる円柱形状又は角柱形状をなしているため、上記のような方法で駆動軸に対するアングル軸の角度を測定する場合、次のような問題がある。   However, since the conventional test bar has a cylindrical shape or a prism shape extending in the direction of the angle axis, there are the following problems when measuring the angle of the angle axis with respect to the drive axis by the method described above.

すなわち、アングル軸がワークテーブルの移動方向であるX軸方向あるいはＹ軸方向のいずれか一方向と平行であれば、当該一方向に測定子を移動させるとともにアングルヘッドを駆動軸方向（例えば、Ｚ軸方向）に移動させることで、測定子をテストバーの軸方向の複数点で接触させ、駆動軸に対するアングル軸の角度を測定することができるが、アングル軸が、Ｘ軸方向及びＹ軸方向のいずれの方向に対しても平行でない場合、上記のような測定子を一方向に移動させる測定方法では、駆動軸に対するアングル軸の角度を測定することができない。   That is, if the angle axis is parallel to either the X-axis direction or the Y-axis direction, which is the moving direction of the work table, the probe is moved in the one direction and the angle head is moved in the drive axis direction (for example, Z By moving the probe in the axial direction of the test bar, it is possible to measure the angle of the angle axis with respect to the drive axis. If it is not parallel to any of these directions, the angle of the angle axis with respect to the drive axis cannot be measured by the measurement method in which the probe is moved in one direction as described above.

特に、駆動軸を収納する駆動側ケーシングとアングル軸を収納するヘッドケーシングとが、駆動軸及びアングル軸に対して所定角度をなす傾斜面により互いに回転自在に連結されたユニバーサルタイプと呼ばれるアングルヘッドが知られているが、このようなアングルヘッドでは、該傾斜面を摺動させながら駆動軸回りにヘッドケーシングを回転させることで駆動軸に対するアングル軸の角度を設定するため、角度調整するたびにX軸方向あるいはＹ軸方向に対するアングル軸の方向が変化することとなる。そのため、常に、アングル軸をX軸方向あるいはＹ軸方向のいずれかの方向と平行に設定することは非常に困難である。   In particular, there is an angle head called a universal type in which a drive-side casing that houses a drive shaft and a head casing that houses an angle shaft are connected to each other by inclined surfaces that form a predetermined angle with respect to the drive shaft and the angle shaft. As is known, in such an angle head, the angle of the angle shaft with respect to the drive shaft is set by rotating the head casing around the drive shaft while sliding the inclined surface. The direction of the angle axis with respect to the axial direction or the Y-axis direction changes. For this reason, it is very difficult to always set the angle axis parallel to either the X-axis direction or the Y-axis direction.

もっとも、テストバーが角柱形状であれば、テストバーの一側面を駆動軸と平行に設定し、測定子をＸ軸方向及びＹ軸方向に移動させることでテストバーの一側面上の複数点で接触させ、Ｘ軸方向又はＹ軸方向に対するアングル軸の傾斜角度を検出し、この検出した傾斜角度に基づいてアングルヘッドを駆動軸回りに回転させ、Ｘ軸方向又はＹ軸方向のいずれか一方向に対してアングル軸が平行になるように調整することで、駆動軸に対するアングル軸の角度を測定することもできる。   However, if the test bar has a prismatic shape, one side of the test bar is set parallel to the drive axis, and the probe is moved in the X-axis direction and the Y-axis direction at multiple points on one side of the test bar. Contact is detected, the angle of inclination of the angle axis with respect to the X-axis direction or the Y-axis direction is detected, the angle head is rotated around the drive axis based on the detected inclination angle, and either the X-axis direction or the Y-axis direction By adjusting so that the angle axis is parallel to the angle, the angle of the angle axis with respect to the drive axis can also be measured.

しかしながら、角柱形状のテストバーでは、駆動軸とアングル軸の取付角度によって、Ｘ軸方向又はＹ軸方向に対するアングル軸の傾斜角度を検出する際の測定子の移動可能な距離が極端に短くなり、精度良く傾斜角度を検出できないことがあり問題である。   However, in the prismatic test bar, the distance that the probe can move when detecting the tilt angle of the angle axis with respect to the X-axis direction or the Y-axis direction becomes extremely short depending on the mounting angle between the drive shaft and the angle shaft. There is a problem that the tilt angle cannot be detected with high accuracy.

また、先端に球を有するテストバーを斜め穴加工装置の回転工具軸に取付け、テストバーを回転工具軸に対して突出量を変えた時の２ヶ所の球の位置を読み取り、傾斜角度を算出する場合がある（下記特許文献２参照）。   In addition, a test bar with a sphere at the tip is attached to the rotary tool shaft of the slant hole drilling device, and the tilt angle is calculated by reading the positions of the two spheres when the test bar is moved with respect to the rotary tool shaft. (See Patent Document 2 below).

しかしこの場合は、斜め穴加工装置の回転工具軸は、直交する二方向の移動軸に斜めに旋回し、２次元平面内でのテストバーの変化を測定するだけである。
特開昭６０−１７７８４８号公報 特開平４−０６３６６５号公報 In this case, however, the rotary tool axis of the oblique hole drilling device is rotated obliquely about two orthogonal movement axes, and only changes in the test bar in the two-dimensional plane are measured.

本発明は、上記問題に鑑みてなされたものであり、測定子をワークテーブル上に載置した状態でワークテーブルを互いに直交する２軸方向に移動させることで、駆動軸に対するアングル軸の角度を正確に測定することができる測定治具及びそれを用いた角度測定方法を提供することを目的とする。   The present invention has been made in view of the above problems, and by moving the work table in two axial directions orthogonal to each other while the probe is placed on the work table, the angle of the angle shaft with respect to the drive shaft is changed. An object of the present invention is to provide a measuring jig capable of accurately measuring and an angle measuring method using the same.

本発明に係る測定治具は、工作機械主軸に接続される駆動軸と、前記駆動軸に連動連結されたアングル軸と、を有する工具ホルダの前記駆動軸に対する前記アングル軸の角度を測定するために用いられる角度測定治具において、前記アングル軸に取り付けられる取付部と、前記アングル軸に対して垂直な平面部と、を備え、前記平面部は、その平面内において直交する２方向の各々の方向における２点間の距離が測定可能な大きさを有していることを特徴とする。   The measuring jig according to the present invention is for measuring an angle of the angle shaft with respect to the drive shaft of a tool holder having a drive shaft connected to a machine tool main shaft and an angle shaft linked to the drive shaft. The angle measuring jig used in the invention includes an attachment portion attached to the angle shaft and a plane portion perpendicular to the angle axis, and the plane portion is in each of two directions orthogonal to each other in the plane. The distance between two points in the direction has a measurable size.

このように本発明では、アングル軸に取り付けられる取付部に対して垂直な平面部は、その平面内において直交する２方向の各々の方向における２点間の距離が測定可能な領域を有するため、角柱形状のテストバーのようにアングル軸回りの取付角度に依存することなく該平面部を一定に保つことができ、常に精度良く駆動軸に対するアングル軸の角度を測定することができる。   Thus, in the present invention, the plane portion perpendicular to the attachment portion attached to the angle shaft has a region where the distance between two points in each of the two directions orthogonal to each other in the plane can be measured. The plane portion can be kept constant without depending on the mounting angle around the angle axis as in the case of a prismatic test bar, and the angle of the angle axis with respect to the drive axis can always be measured with high accuracy.

また、本発明に係る角度測定方法は、工作機械主軸に接続される駆動軸と、前記駆動軸に連動連結されたアングル軸と、を有する工具ホルダであり、前記駆動軸に対する前記アングル軸の角度を、前記駆動軸と垂直な平面内の互いに直交する２方向と駆動軸方向に測定子を移動させることで測定する角度測定方法において、前記アングル軸の先端に該アングル軸に垂直な平面を設け、前記測定子を前記駆動軸と垂直な平面内の一方向に移動させて、前記一方向に対する前記平面の傾きを検出し、前記検出した傾きに基づいて、前記工具ホルダを前記駆動軸回りに回転させて前記平面を前記一方向に対して平行に設定し、次いで、前記測定子を前記一方向に直交する他方向に移動させるとともに前記工具ホルダを前記駆動軸方向に移動させて、前記測定子を前記平面の少なくとも２点を測定することで、前記駆動軸に対する前記アングル軸の角度を測定することを特徴とする。   The angle measuring method according to the present invention is a tool holder having a drive shaft connected to a machine tool main shaft and an angle shaft linked to the drive shaft, and an angle of the angle shaft with respect to the drive shaft In the angle measuring method for measuring the angle by moving the probe in two directions perpendicular to each other in the plane perpendicular to the drive axis and the direction of the drive axis, a plane perpendicular to the angle axis is provided at the tip of the angle axis. The probe is moved in one direction in a plane perpendicular to the drive axis, and the inclination of the plane with respect to the one direction is detected, and the tool holder is moved around the drive axis based on the detected inclination. Rotate to set the plane parallel to the one direction, then move the probe in the other direction orthogonal to the one direction and move the tool holder in the drive axis direction, Serial By measuring at least two points of the planar measuring element, and measuring the angle of the angle shaft relative to the drive shaft.

本発明によれば、駆動軸と垂直な平面内の互いに直交する２方向に測定子を移動させて前記駆動軸に対する前記アングル軸の角度を容易にかつ精度良く測定することができる。   According to the present invention, it is possible to easily and accurately measure the angle of the angle shaft with respect to the drive shaft by moving the measuring element in two directions perpendicular to each other in a plane perpendicular to the drive shaft.

以下、本発明の一実施形態について図面を参照して説明する。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

図１は本実施形態にかかる測定治具１０の斜視図であり、図２は測定治具１０を工具ホルダ１００に取り付けた状態を示す工具ホルダ１００の断面図、図３は測定治具１０の使用状態を示す側面図、図４は測定治具１０の使用状態を示す平面図である。   FIG. 1 is a perspective view of a measurement jig 10 according to the present embodiment, FIG. 2 is a sectional view of the tool holder 100 showing a state in which the measurement jig 10 is attached to the tool holder 100, and FIG. FIG. 4 is a plan view showing a usage state of the measuring jig 10.

本実施形態に係る測定治具１０は、図２、３に示すように、工作機械主軸１に同軸状に接続される駆動軸１１０と、駆動軸１１０に対する角度が調整可能なアングル軸１４０とを有するユニバーサルタイプの工具ホルダ１００のアングル軸１４０に接続され、駆動軸１１０に対するアングル軸１４０の角度θを測定するために用いられるものである。   As shown in FIGS. 2 and 3, the measurement jig 10 according to the present embodiment includes a drive shaft 110 that is coaxially connected to the machine tool spindle 1 and an angle shaft 140 that can adjust an angle with respect to the drive shaft 110. It is connected to the angle shaft 140 of the universal type tool holder 100 and has a function of measuring the angle θ of the angle shaft 140 with respect to the drive shaft 110.

詳細には、工具ホルダ１００の駆動軸１１０は、工作機械主軸１のテーパ孔２に嵌合されるテーパシャンク部１１２と、駆動側ケーシング１２０に軸受１１４を介して回転可能に支承される支承軸部１１６とからなり、支承軸部１１６の先端部はジョイント１１７を介してアングル軸１４０が連動連結されている。アングル軸１４０は、ヘッドケーシング１４２に軸受１４４を介して回転可能に支承されており、先端部に切削具などを取り付けるチャック１４６が設けられている。   Specifically, the drive shaft 110 of the tool holder 100 includes a taper shank portion 112 fitted in the taper hole 2 of the machine tool main shaft 1 and a support shaft that is rotatably supported by the drive-side casing 120 via a bearing 114. The angle shaft 140 is interlocked and connected to the tip end portion of the support shaft portion 116 via a joint 117. The angle shaft 140 is rotatably supported on the head casing 142 via a bearing 144, and a chuck 146 for attaching a cutting tool or the like is provided at the tip.

駆動側ケーシング１２０は基端ケーシング１２２と先端ケーシング１２４に分割されており、先端ケーシング１２４が基端ケーシング１２２に対して駆動軸１１０回りに回転自在に連結されている。   The drive side casing 120 is divided into a base end casing 122 and a front end casing 124, and the front end casing 124 is connected to the base end casing 122 so as to be rotatable around the drive shaft 110.

基端ケーシング１２２の外周面には、工作機械側本体３の端面に向かって進退可能な固定用ピン１２６を嵌入されるピン保持台１２８が突設されており、工作機械側本体３の端面に設けられた凹部４に固定用ピン１２６が嵌合することで、固定用ピン１２６を介して基端ケーシング１２２が回転不能に固定される。   On the outer peripheral surface of the base end casing 122, a pin holding base 128 into which a fixing pin 126 that can be advanced and retracted toward the end surface of the machine tool side main body 3 is fitted. When the fixing pin 126 is fitted into the provided recess 4, the proximal casing 122 is fixed to be non-rotatable via the fixing pin 126.

先端ケーシング１２４の端面は、駆動軸１１０に対して所定角度の傾斜面１２４ａをなしヘッドケーシング１４２が回転自在に連結されており、傾斜面１２４ａを摺動させながら駆動軸１１０回りにヘッドケーシング１４２を回転させることで、駆動軸１１０に対するアングル軸１４０の角度θを調整するようになっている。   An end surface of the tip casing 124 forms an inclined surface 124a having a predetermined angle with respect to the drive shaft 110, and the head casing 142 is rotatably connected. The head casing 142 is rotated around the drive shaft 110 while sliding on the inclined surface 124a. By rotating, the angle θ of the angle shaft 140 with respect to the drive shaft 110 is adjusted.

測定治具１０は、アングル軸１４０にチャック１４６を介して取り付けられる取付部１２と、この取付部１２に対して垂直な平面を有する平面部１４とを備えている。平面部１４は、駆動軸１１０に垂直な平面内の互いに直交するＸ軸方向及びＹ軸方向の２軸方向に移動可能なワークテーブル５０上に載置された測定子４０を接触させることで、平面部１１４の平面内において直交する２方向の各々の方向における２点間の距離を測定することができ、これにより、駆動軸方向（本実施形態では、Ｚ軸方向）、Ｘ軸方向、あるいはＹ軸方向に対する上記距離を測定した方向の角度測定が可能な大きさ（領域）を有する平板形状をなしており、一例を挙げると直径６０ｍｍ程度の円板形状をなしている。   The measuring jig 10 includes an attachment portion 12 attached to the angle shaft 140 via a chuck 146 and a flat portion 14 having a plane perpendicular to the attachment portion 12. The flat surface portion 14 is brought into contact with a measuring element 40 placed on a work table 50 that is movable in two axial directions of the X axis direction and the Y axis direction orthogonal to each other in a plane perpendicular to the drive shaft 110. The distance between two points in each of the two directions orthogonal to each other in the plane of the plane portion 114 can be measured, whereby the drive axis direction (in this embodiment, the Z axis direction), the X axis direction, or It has a flat plate shape having a size (region) capable of measuring the angle in the direction in which the distance with respect to the Y-axis direction is measured. For example, it has a disk shape with a diameter of about 60 mm.

このような測定治具１０を用いて駆動軸１１０に対するアングル軸１４０の角度θを測定するには、次の手順により行う。   In order to measure the angle θ of the angle shaft 140 with respect to the drive shaft 110 using such a measuring jig 10, the following procedure is performed.

まず、第１工程として、図４に示すように、ワークテーブル５０を移動させて平面部１４に測定子４０を接触させる。そして、測定子４０を平面部１４に接触させながらＸ−Ｙ軸方向のいずれか一方向（本実施形態では、Ｙ軸方向）にワークテーブル５０を所定量δＹ１移動させ、これにより測定子４０が計測したＸ軸方向の変位量δＸ１からＹ軸方向に対する平面部１４の傾斜角度φを下記式（１）により検出する。 First, as a first step, as shown in FIG. 4, the work table 50 is moved to bring the probe 40 into contact with the flat surface portion 14. Then, the work table 50 is moved by a predetermined amount δ Y1 in any one of the XY axis directions (in this embodiment, the Y axis direction) while the measuring element 40 is in contact with the flat surface portion 14. The inclination angle φ of the plane portion 14 with respect to the Y-axis direction is detected from the displacement amount δ X1 in the X-axis direction measured by the following equation (1).

φ＝ｔａｎ−１（δＸ１／δＹ１）…（１）
なお、測定子４０を平面部１４に接触させながらＸ軸方向の変位量δｘを測定する代わりに、ワークテーブル５０をＸ，Ｙ軸方向それぞれに移動させ測定子４０を平面部１４の２点で接触させて、そのときのＸ軸方向の変位量δＸ１及びＹ軸方向の移動量δＹ１から上記式（１）に基づきＹ軸方向に対する平面部１４の傾斜角度φを検出してもよい。 φ = tan −1 (δ X1 / δ Y1 ) (1)
Instead of measuring the displacement amount δx in the X-axis direction while bringing the measuring element 40 into contact with the flat surface part 14, the work table 50 is moved in each of the X and Y-axis directions to move the measuring element 40 at two points on the flat surface part 14. The inclination angle φ of the plane portion 14 with respect to the Y-axis direction may be detected from the displacement amount δ X1 in the X-axis direction and the movement amount δ Y1 in the Y-axis direction at that time based on the above formula (1).

次いで、第２工程として、検出した傾斜角度φに基づいて、平面部１４がＹ軸方向に対して平行になるように、基端ケーシング１２２に対して先端ケーシング１２４を駆動軸１１０回りに回転させる。   Next, as a second step, based on the detected inclination angle φ, the distal end casing 124 is rotated around the drive shaft 110 with respect to the proximal end casing 122 so that the planar portion 14 is parallel to the Y-axis direction. .

次いで、第３工程として、図３に示すように、ワークテーブル５０をＸ軸方向に移動させるとともに工具ホルダ１００を駆動軸方向に移動させ測定子４０を平面部１４の２点で接触させて、そのときのＸ軸方向の変位量δＸ２及びＺ軸方向の移動量δＺ２から下記式（２）に基づき駆動軸１１０に対するアングル軸１４０の角度θを測定する。 Next, as a third step, as shown in FIG. 3, the work table 50 is moved in the X-axis direction, the tool holder 100 is moved in the drive axis direction, and the tracing stylus 40 is brought into contact at two points on the plane portion 14. The angle θ of the angle shaft 140 with respect to the drive shaft 110 is measured from the displacement amount δ X2 in the X-axis direction and the movement amount δ Z2 in the Z-axis direction based on the following formula (2).

θ＝ｔａｎ−１（δＺ２／δＸ２）…（２）
以上のように本発明では、測定子４０と接触する平面部１４が、アングル軸１４０に垂直な平面であるため、測定治具１０のアングル軸回りの取付角度に依存することなく、常に測定子４０が接触可能な領域を充分に確保することができ正確な角度測定が可能となる。 θ = tan −1 (δ Z2 / δ X2 ) (2)
As described above, in the present invention, since the flat portion 14 in contact with the probe 40 is a plane perpendicular to the angle shaft 140, the probe is always independent of the mounting angle around the angle axis of the measurement jig 10. It is possible to secure a sufficient area where 40 can be contacted and to perform accurate angle measurement.

また、本実施形態のようなユニバーサルタイプの工具ヘッドでは、ヘッドケーシング１４２を先端ケーシング１２４に対して駆動軸１１０回りに回転させて、駆動軸１１０に対するアングル軸１４０の角度θを調整するようになっているため、駆動軸１１０に対するアングル軸１４０の角度θを調整するごとにＹ軸方向に対するアングル軸１４０の角度φが変化するが、このような場合であっても、上記した第１工程、第２工程及び第３工程を順次行うことで正確な駆動軸１１０に対するアングル軸１４０の角度θを測定することができる。   In the universal type tool head as in this embodiment, the head casing 142 is rotated around the drive shaft 110 with respect to the tip casing 124 to adjust the angle θ of the angle shaft 140 with respect to the drive shaft 110. Therefore, every time the angle θ of the angle shaft 140 with respect to the drive shaft 110 is adjusted, the angle φ of the angle shaft 140 with respect to the Y-axis direction changes. Even in such a case, the first step, The angle θ of the angle shaft 140 relative to the drive shaft 110 can be accurately measured by sequentially performing the second step and the third step.
