Description

The present invention relates to a stylus for copying a workpiece, for example, a homogeneous industrial part (hereinafter referred to as a workpiece) processed by a machine tool, die casting, injection molding, press punching, lost wax casting, die forging, etc. For example, the present invention relates to a work devised as a copy of the shape of a work when chamfering the work manufactured by the method.

For example, a workpiece manufactured by a method such as machining with a machine tool, die casting, injection molding, press punching, lost wax casting, die forging, or the like is shown in FIG. The workpiece 401 shown in FIG. 26 has a relatively complicated shape in which the two-dimensional contour is connected by a straight line and a curved line. Further, the workpiece 401 has a flange shape, and a through hole 403 through which a shaft (not shown) passes is formed at the center, and through holes 405 through which fastening bolts (not shown) pass are formed at the four corners. . An annular recess 407 is formed on the outer periphery of the through hole 403. The annular recess 407 has a plurality of protrusions 409 protruding from a plurality of locations. The workpiece 401 having such a configuration is fastened and fixed together with another workpiece (not shown) to be completed as a predetermined device.

In the case of the workpiece 401 as shown in FIG. 26, high dimensional accuracy is required for the pitches (P ₁ ), (P ₂ ), etc. between the through holes 405, 405, but the absolute shape of the contour shape is required. The dimensional accuracy is not so important. On the other hand, in the manufacturing process, it is necessary to remove a so-called “burr” generated at the outer peripheral edge. Further, it is necessary to perform chamfering according to the contour shape or finish the end surface with a certain processing surface accuracy. At that time, when only deburring is performed, a flexible tool such as a brushing wheel or a wire wheel may be used. However, chamfering is performed according to the contour shape, or the end surface is set to a fixed processing surface. When finishing with precision, a cutting tool such as an end mill, a rotary bar, or a chamfer cutter is used.

There are various types of cutting devices that perform finishing using the cutting tool. However, all of the conventional devices of this type move cutting tools based on trajectory information set in advance based on model workpieces, etc. Therefore, when there is a variation in the workpiece contour shape (the workpiece actually processed with respect to the contour shape of the model workpiece has a variation), the depth of cutting Therefore, there is a problem that the cutting depth is too deep and the chamfer width becomes large depending on the location, or the tool is damaged depending on the location.
Another problem is that it is difficult to input and store the trajectory information in advance. That is, when inputting trajectory information, first, it is necessary to set a large number of programming points along the contour shape of the model work, and to set the coordinate values of those programming points. The value is input and stored using the teaching box. These operations are by no means easy and require a lot of labor and a long working time.

Therefore, the present applicant of the present patent proposes an invention called “following processing apparatus”. The details are disclosed in Patent Document 1.

Japanese Patent Laid-Open No. 5-200655

However, the following machining apparatus described in Patent Document 1 is configured to detect the pressing force when the machining tool is brought into pressure contact with the workpiece by the load sensor, and the overall configuration is simplified and the operation is easy. However, there is a problem in that the configuration for the program control by the servo motor based on the detection value of the load sensor is complicated, which causes the apparatus to be expensive.
Therefore, the present patent applicant has proposed a “processing apparatus” that performs desired processing without requiring such an expensive apparatus or complicated control. Patent Document 2 discloses this.

JP 10-193239 A

  The following processing device is disclosed in Patent Document 2 described above. In other words, the head portion including the machining tool unit is installed so as to be able to advance and retreat with respect to the workpiece, and is configured to be pressed against the inner diameter portion or the outer diameter portion of the workpiece. Then, as the work rotates, the stylus advances and retreats following the shape of the outer diameter part or inner diameter part of the work. Thereby, the head part provided with the processing tool unit moves forward and backward. Thereby, the workpiece is chamfered by a tool provided in the machining tool unit.

In addition, there are, for example, Patent Document 3 and Patent Document 4 that disclose similar types of processing apparatuses.
