【発明の属する技術分野】
本発明は研削盤や旋盤など多軸制御機械の刃具とワークのセンター合わせ、いわゆる芯高合わせを高精度かつ簡便に行う方法に関する。
【０００２】
【従来の技術】
従来、研削盤や旋盤など多軸制御機械の芯高合わせは図５、図６および図７に示すように、ダミーワーク１７をワークチャック２に保持し、刃具１５を使ってまず刃具１５の先端形状をダミーワーク１７に転写させ転写跡１８を形成する。次にθ回転軸４すなわちワークチャック２を１８０度回転させ、前記と同様に刃具１５の先端形状をダミーワーク１７に転写させ転写跡１９を形成する。そして、転写跡１８と転写跡１９との中心線間の距離Ｌ３を測長し、この距離Ｌ３が０になるように前記の転写作業を繰り返す方法が一般的に行われている。
【０００３】
【発明が解決しようとする課題】
芯高合わせの精度が低いとワークの加工精度の中でも特に形状精度に影響を及ぼすばかりでなく、機械本体および刃具の寿命にも悪影響を及ぼすことが一般的に知られている。
【０００４】
しかしながら、前記の従来技術に示した芯高合わせ方法では、距離Ｌ３の測長に誤差がともなうこと、距離Ｌ３の測長の際ダミーワーク１７をワークチャック２からはずし、測長後再びダミーワーク１７をワークチャック２に把持させた時の取り付け誤差など、高精度な芯高合わせを行うことは熟練が必要で簡便かつ高精度に芯高合わせが行える方法が望まれていた。
【０００５】
そこで本発明は、このような問題点を解決し、芯高合わせの中でも特に刃具の先端が回転対称形状をした刃具を用いる場合の芯高合わせを高精度かつ簡便に行う方法を提供することにある。
【０００６】
【課題を解決するための手段】
【０００７】
本発明は前記目的を達成するもので、水平方向に直線位置決めを行うＸ軸位置決め手段と、前記Ｘ軸位置決め手段と直交する水平方向に直線位置決めを行うＹ軸位置決め手段と、回転対称形状を有し、先端が円弧形状の刃具と、前記刃具を軸に取り付ける手段を有するスピンドル軸と、前記スピンドル軸を回転させる手段と、前記Ｘ軸位置決め手段もしくは前記Ｙ軸位置決め手段に接合され前記スピンドル軸部を鉛直方向に位置決めするＺ軸位置決め手段と、前記Ｘ軸位置決め手段もしくは前記Ｙ軸位置決め手段に接合され前記スピンドル軸と直交する方向に回転軸を有しワークを保持回転させる角度割り出し機能を有するワーク回転手段と、前記ワーク回転手段基準で作られたチャック部とを有する多軸制御機械を用いて刃具とワークの芯高合わせを行う方法において、前記ワーク回転手段のチャック部に把持され、任意の基準点から前記刃具までの距離を非接触で測長する計測手段を備えた刃具とワークの芯高を合わせる装置を用い、該装置を前記ワーク回転手段で任意の回転位置から１８０度正逆転させ、正転時および逆転時の前記任意の基準点と刃具との距離を測長し、それぞれに測長された距離の差を求めることを特徴とする。
【０００８】
【作用】
本発明の刃具とワークの芯高合わせ方法は、水平方向に直線位置決めを行うＸ軸位置決め手段と、前記Ｘ軸位置決め手段と直交する水平方向に直線位置決めを行うＹ軸位置決め手段と、回転対称形状を有し、先端が円弧形状の刃具と、前記刃具を軸に取り付ける手段を有するスピンドル軸と、前記スピンドル軸を回転させる手段と、前記Ｘ軸位置決め手段もしくは前記Ｙ軸位置決め手段に接合され前記スピンドル軸部を鉛直方向に位置決めするＺ軸位置決め手段と、前記Ｘ軸位置決め手段もしくは前記Ｙ軸位置決め手段に接合され前記スピンドル軸と直交する方向に回転軸を有しワークを保持回転させる角度割り出し機能を有するワーク回転手段と、前記ワーク回転手段基準で作られたチャック部とを有する多軸制御機械の前記ワーク回転手段のチャック部に把持され、任意の基準点から前記刃具までの距離を非接触で測長する計測手段を備えた刃具とワークの芯高を合わせる装置を用い、該装置を前記ワーク回転手段で任意の回転位置から１８０度正逆転させ、正転時および逆転時の前記任意の基準点と刃具との距離を測長し、それぞれに測長された距離の差を求め、ワークのセンターと刃具のセンターすなわち芯高を合わせることにより、従来方法に比べ大幅に高精度かつ簡便に芯高を合わせることができる。
【０００９】
【発明の実施の形態】
以下、本発明の一実施例を図面に基づいて説明するが、これらに限定されるものではない。
【００１０】
図１は該実施例の多軸制御機械とワークチャックに把持された芯高合わせ装置の側面図、図２は該実施例の芯高合わせ装置と刃具部分の拡大図である。
【００１１】
図１および図２において、１は本発明の芯高合わせ装置、１６は測長用センサーである。５はほぼ水平方向に直線位置決めを行うＸ軸位置決め手段、６はＸ軸駆動用のモータおよびエンコーダである。８はＸ軸位置決め手段５と直交するほぼ水平方向に直線位置決めを行うＹ軸位置決め手段、９はＹ軸駆動用のモータおよびエンコーダである。１３は図示していないモータを内蔵し刃具を回転させるためのスピンドルユニットであり、１４はスピンドル軸、１５は形状誤差が＋０．００５〜−０．００５［ｍｍ］で２［ｍｍ］の曲率半径をもつ切削用の刃具である。スピンドル軸１４の軸端にはスピンドル軸１４の回転軸と刃具１５の回転軸が一致するように刃具１５が取り付けられている。１２はほぼ鉛直方向に位置決め可能なＺ軸位置決め手段である。スピンドルユニット１３および刃具１５はＺ軸位置決め手段１２によって移動できるため、図示しないワークあるいは芯高合わせ装置の高さに応じた鉛直方向の位置決めが可能である。また、１１はＺ軸駆動用のモータおよびエンコーダである。
【００１２】
なお、図示していないがＸ軸位置決め手段５とＹ軸位置決め手段８、およびＺ軸位置決め手段１２には位置検出手段としてリニアスケールが内蔵されている。
【００１３】
次に４はＸ軸位置決め手段５上でスピンドル軸１４の回転軸と直交するほぼ水平方向に回転軸を有し図示しないワークあるいは芯高合わせ装置１を保持回転させる角度位置の制御が可能なθ回転軸である。２はθ回転軸４上でθ回転軸４の回転軸にワーク回転軸を一致させワークあるいは芯高合わせ装置１を保持するワークチャックである。
【００１４】
続いてこれらの構成で芯高を合わせる方法について説明する。
【００１５】
まずスピンドル軸１４を適当な回転数で回転させ、図３に示す刃具１５と芯高合わせ装置１の位置で芯高合わせ装置１の基準面すなわち非接触式測長用センサー１６の端面から刃具１５の表面までの距離Ｌ１を計測する。次に図３に示す位置からθ回転軸４を１８０度回転する。この状態を図４に示す。図４に示す状態で前記と同様に芯高合わせ装置１の基準面と刃具１５との距離Ｌ２を計測する。
【００１６】
次に、このＬ１とＬ２との差が０に近づくようにＺ軸位置決め手段１２によってスピンドルユニット１３および刃具１５を芯高合わせ装置に対して鉛直方向に上下移動させる。前記Ｌ１、Ｌ２の計測とＺ軸位置決め手段１２を使った鉛直方向の位置決めによってＬ１とＬ２との差が０になれば刃具１５のセンターとワークチャック２すなわちワーク回転軸のセンターが一致し芯高合わせが完了となる。
【００１７】
一方、従来方法を図５、図６および図７に示す。まず、Ｙ軸位置決め手段８により適量切り込みを入れ、図５に示すようにダミーワーク１７に刃具１５の先端形状を切削転写し転写跡１８をつける。次に図５に示す位置からθ回転軸４を１８０度回転し同様にダミーワーク１７に刃具１５の先端形状を切削転写し転写跡１９をつける。この状態を図６に示す。
【００１８】
するとダミーワーク１７には図７に示すように転写跡１８および１９が切削転写されている。図７に示すＬ３を測長しＬ３の半分の長さ分を相対的に移動することにより芯高合わせを行っていた。
【００１９】
該実施例に示す芯高合わせ方法と従来方法との芯高の精度を比較したところ従来比約２０倍の高精度な芯高合わせを行うことが確認された。またワークの加工精度も従来比５倍となり、加工精度の向上も確認された。
【００２０】
該実施例では２［ｍｍ］の曲率半径をもった刃具を用いたが回転対称形状をしていれば、特定の曲率半径に限定されることは言うまでもない。
【００２１】
また、該実施例では測長用のセンサーは非接触のものを用いたが、接触式のものを用いても同様に高精度な芯高合わせを行うことができることは言うまでもない。
【００２２】
【発明の効果】
以上述べたように本発明の刃具とワークの芯高合わせ方法によれば、Ｘ軸位置決め手段、Ｙ軸位置決め手段、回転対称形状を有し、先端が円弧形状の刃具と、前記刃具を軸に取り付け回転させるスピンドル軸、前記スピンドル軸部を鉛直方向に位置決めするＺ軸位置決め手段、前記スピンドル軸と直交する方向に回転軸を有しワークを保持回転させる角度割り出し機能を有するワーク回転手段と、前記ワーク回転手段基準で作られたチャック部とを有する多軸制御機械の前記ワーク回転手段のチャック部に把持され、任意の基準点から前記刃具までの距離を非接触で測長する計測手段を備えた刃具とワークの芯高を合わせる装置を用い、該装置を前記ワーク回転手段で任意の回転位置から１８０度正逆転させ、正転時および逆転時の前記任意の基準点と刃具との距離を測長し、それぞれに測長された距離の差を求め、ワークのセンターと刃具のセンターすなわち芯高を合わせることにより、従来方法に比べ大幅に高精度かつ簡便に芯高を合わせることができるという効果を有する。

Conventionally, as shown in FIGS. 5, 6, and 7, the center height alignment of a multi-axis control machine such as a grinding machine or a lathe is performed by holding the dummy workpiece 17 on the work chuck 2 and using the cutting tool 15 first. The shape is transferred to the dummy workpiece 17 to form a transfer mark 18. Next, the θ rotation shaft 4, that is, the work chuck 2 is rotated 180 degrees, and the tip shape of the blade 15 is transferred to the dummy work 17 in the same manner as described above to form a transfer mark 19. A method is generally employed in which the distance L3 between the center lines of the transfer trace 18 and the transfer trace 19 is measured, and the above transfer operation is repeated so that the distance L3 becomes zero.
[0003]
[Problems to be solved by the invention]
It is generally known that a low centering accuracy not only affects the shape accuracy among the workpiece processing accuracy, but also adversely affects the life of the machine body and the cutting tool.
[0004]
However, in the center height alignment method shown in the above prior art, there is an error in the measurement of the distance L3. When measuring the distance L3, the dummy workpiece 17 is removed from the work chuck 2, and after the measurement, the dummy workpiece 17 is mounted again. Highly accurate center height alignment, such as attachment errors when gripped by the work chuck 2, requires skill, and a method that can easily and accurately align the center height has been desired.
[0005]
Accordingly, the present invention provides a method for solving such problems and performing high-precision and simple core height alignment when using a blade tool in which the tip of the blade tool has a rotationally symmetric shape, particularly among the core height alignment. is there.
[0006]

[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, although one Example of this invention is described based on drawing, it is not limited to these.
[0010]
FIG. 1 is a side view of a multi-axis control machine according to this embodiment and a center height adjusting device held by a work chuck, and FIG. 2 is an enlarged view of the center height adjusting device and the cutting tool portion according to this embodiment.
[0011]
1 and 2, reference numeral 1 denotes a center height adjusting device of the present invention, and 16 denotes a length measuring sensor. Reference numeral 5 denotes an X-axis positioning means for linearly positioning in a substantially horizontal direction, and 6 denotes an X-axis drive motor and encoder. Reference numeral 8 denotes Y-axis positioning means for linearly positioning in a substantially horizontal direction orthogonal to the X-axis positioning means 5, and 9 denotes a motor and encoder for driving the Y-axis. 13 is a spindle unit for incorporating a motor (not shown) to rotate the cutting tool, 14 is a spindle shaft, 15 is a radius of curvature of 2 [mm] with a shape error of +0.005 to -0.005 [mm]. It is a cutting tool for cutting. A blade 15 is attached to the shaft end of the spindle shaft 14 so that the rotation axis of the spindle shaft 14 and the rotation axis of the blade 15 coincide. Reference numeral 12 denotes a Z-axis positioning means which can be positioned substantially in the vertical direction. Since the spindle unit 13 and the cutting tool 15 can be moved by the Z-axis positioning means 12, positioning in the vertical direction according to the height of the workpiece or the center height adjusting device (not shown) is possible. Reference numeral 11 denotes a Z-axis drive motor and encoder.
[0012]
Although not shown, the X-axis positioning unit 5, the Y-axis positioning unit 8, and the Z-axis positioning unit 12 incorporate a linear scale as a position detection unit.
[0013]
Next, reference numeral 4 denotes an X axis positioning means 5 having a rotation axis in a substantially horizontal direction orthogonal to the rotation axis of the spindle shaft 14 and capable of controlling the angular position for holding and rotating the workpiece or the centering device 1 not shown. It is a rotation axis. Reference numeral 2 denotes a work chuck that holds the work or center height aligning device 1 by aligning the work rotation axis with the rotation axis of the θ rotation axis 4 on the θ rotation axis 4.
[0014]
Next, a method for adjusting the core height with these configurations will be described.
[0015]
First, the spindle shaft 14 is rotated at an appropriate number of revolutions, and the cutting tool 15 is moved from the reference plane of the core height adjusting device 1 at the position of the blade height adjusting device 1 shown in FIG. The distance L1 to the surface of is measured. Next, the θ rotation shaft 4 is rotated 180 degrees from the position shown in FIG. This state is shown in FIG. In the state shown in FIG. 4, the distance L <b> 2 between the reference surface of the center height adjusting device 1 and the cutting tool 15 is measured in the same manner as described above.
[0016]
Next, the spindle unit 13 and the blade 15 are moved up and down in the vertical direction by the Z-axis positioning means 12 so that the difference between L1 and L2 approaches zero. If the difference between L1 and L2 is zero by the measurement of L1 and L2 and the vertical positioning using the Z-axis positioning means 12, the center of the cutting tool 15 and the center of the work chuck 2, that is, the center of the work rotation axis coincide with each other. Matching is complete.
[0017]
On the other hand, the conventional method is shown in FIGS. First, an appropriate amount of cut is made by the Y-axis positioning means 8, and the tip shape of the cutting tool 15 is cut and transferred to the dummy workpiece 17 as shown in FIG. Next, the θ rotation shaft 4 is rotated 180 degrees from the position shown in FIG. 5, and similarly, the tip shape of the blade 15 is cut and transferred to the dummy work 17 to make a transfer mark 19. This state is shown in FIG.
[0018]
Then, transfer marks 18 and 19 are cut and transferred to the dummy workpiece 17 as shown in FIG. The L3 shown in FIG. 7 is measured, and the center height is adjusted by relatively moving half the length of L3.
[0019]
Comparison of the core height accuracy between the center height alignment method shown in the example and the conventional method confirmed that the center height alignment is performed with a precision of about 20 times that of the conventional method. In addition, the machining accuracy of the workpiece was 5 times that of the conventional one, and it was confirmed that the machining accuracy was improved.
[0020]
In this embodiment, a blade having a curvature radius of 2 [mm] is used, but it goes without saying that it is limited to a specific curvature radius as long as it has a rotationally symmetric shape.
[0021]
In this embodiment, the non-contact sensor is used for measuring the length, but it is needless to say that even if a contact sensor is used, high-precision centering can be performed.
[0022]
