本発明はマスクとなるカムによって機械的に刃物を運動
させ、被加工物の加工面にリードを加工する工作機械に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a machine tool that mechanically moves a blade using a cam serving as a mask to machine a lead on the machined surface of a workpiece.

きる刃物台１４がある。Figure 1 shows a conventional lead processing machine.The main body 1 has a main bearing 2 and a drive motor 3, and a movable table 4 that can move in a plane.
Also installed. A lead converter 5 is fixed thereon. The main shaft 6 supported by the main bearing has a 7 lange 7 at its tip, and a front cam 9 that serves as a mask for the chuck 8 and the lead is attached by a bolt 10.The workpiece 11 is supported by the chuck and Figure 1 shows that a lead is processed on the side surface. The lead converter has a slider 12 that can reciprocate in the axial direction of the main shaft, and has a roller 13 at its tip that moves. The slider has a tool post 14 that can perform the same lead machining movement as the slider, and 4, can independently perform cutting movement.
加工する刃物１５はこの刃物軸に固定されている。The cutting tool 15 to be processed is fixed to this cutting tool shaft.

になる。When the main shaft is rotated by the drive motor, the front cam and the workpiece rotate in the same phase. The roller in contact with the cam surface of the front cam moves according to the profile of the cam surface, and the blade moves via the slider and the tool rest. This causes the profile of the front cam to be transferred to the side surface of the workpiece.
さて、被加工物のリード社外周部に約１８０°にわたシ
、主軸の回転軸に直角な面に対し、６＠のリード角の直
線部を持ち、その直線度は最近、±１μｍという高い精
度が要求されている。Now, there is a straight part on the outer periphery of the workpiece that spans approximately 180 degrees and has a lead angle of 6@ to the plane perpendicular to the axis of rotation of the main spindle, and its straightness has recently been as high as ±1 μm. Precision is required.
しかし、従来のリード加工機においては、主として、マ

リード角をもつが、これは背面２２を基準として加工さ
れ、第１図のリード加工機ＫＩＩＲ，！７つけられる。However, with conventional lead processing machines, it is difficult to process the straightness to ±1 μm mainly due to the front cam that serves as a mask. FIG. 3 is a cross-sectional view of the cam. Cam surface 2
The straight part 1 has a lead angle of angle φ corresponding to the lead angle 6@ of the workpiece, but this is processed with the back surface 22 as a reference, and the lead processing machine KIIR, ! of FIG. 1 is used. 7 can be added.

被加工物のリードはマスクとなる正面カムのプ四ファイ
ルがそのま°ま転写されるからである。When installing the front cam, the back side of this front cam must be at right angles to the rotation axis of the main shaft. this is,
This is because the four files of the front cam, which serve as a mask, are directly transferred to the lead of the workpiece.

間の双方の無駄はきわめて大きく、リード加工のコスト
増にはねかえっている。However, with conventional lead processing machines, when the flat cam is installed, the back surface of the processing reference comes into contact with the 7-lunge surface and is hidden, making it difficult to judge whether the lead angle has been accurately fixed at 75 angles as φ. I couldn't. In order to know this, we had to mill the workpiece, estimate the error in the installation of the front cam from the machined lead, adjust the installation of the front cam, and try the workpiece again. I had to go through trial and error of cutting it down. This trial-and-error process wastes both the workpiece for trial rigidity and the time required for adjustment, which is counterproductive to the increased cost of lead processing.

することである。The purpose of the present invention is to easily fix the front cam, which will serve as a % master, on the 7 flange so that the lead angle is exactly φ without making many trial cuts, and as a result, it is possible to easily fix the front cam that is the master on the 7 flange with an accuracy of ±1 μm. An object of the present invention is to provide a lead processing machine capable of processing leads of a workpiece.
