As shown in FIG. 3, the tapered surface C and the outer diameter portion B were processed based on the inner diameter of the movable sheave 1. Further, as described in Japanese Patent Publication No. 6-49256 shown in FIG. 4, an outer diameter portion (processing reference surface) B is processed using the ball spline groove A of the movable sheave (work) 1 as a processing reference, and further processed. A method of processing the movable sheave 1 for processing the tapered surface C using the reference surface B as a processing reference is known. In this processing method, in order to guarantee processing accuracy in the relationship between the ball spline groove A and the tapered surface C, the mounting accuracy in the ball spline groove A when processing the outer diameter portion (processing reference surface) B is guaranteed. It is assumed that [0003] In the former of the techniques described in the prior art, in the processing of the tapered surface C, if the precision of attaching the work to the chuck is insufficient, the movable sheave 1 is tilted. In this case, there is a problem that the processing accuracy is adversely affected, and the work rigidity on the outer peripheral side is poor, so that only light load processing can be performed. In the latter case, since different standards are required for processing the processing reference surface B and the tapered surface C, errors in mounting the work to the chuck are likely to accumulate. There is a problem that the working accuracy of the movable sheave 1 may be adversely affected. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to achieve a high processing accuracy without accumulating errors in attaching a workpiece to a chuck. An object of the present invention is to provide a method for processing a movable sheave of a pulley device for a continuously variable transmission. SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a pulley for a continuously variable transmission having a movable sheave slidably supported on a shaft of a fixed sheave via a ball spline. a movable sheave processing method of the device, the said grasping the outer periphery finish forming the boss outer diameter portion of the movable sheave boss (E), the inner diameter (D) and the processing reference surface of the next step
An inner diameter portion and a processing reference surface processing step of processing the outer diameter portion (B) , and a taper surface and a spline groove processing of processing the tapered surface (C) and the spline groove (A) of the movable sheave based on the processing reference surface. A process is provided. The inner diameter part (D) and the outer diameter part as a machining reference plane
Simultaneous processing of (B) becomes possible. Based on the machining reference plane
The simultaneous processing of the tapered surface (C) and the spline groove (A)
It becomes possible. That is, the tapered surface (C) and the spline groove (A) of the movable sheave are processed based on only the same processing reference surface. An embodiment of the present invention will be described below with reference to the accompanying drawings. Here, FIG. 1 is a sectional view of a movable sheave processed by a method for processing a movable sheave of a pulley device for a continuously variable transmission according to the present invention, and FIG. In the method for processing a movable sheave of a pulley device for a continuously variable transmission, as shown in FIG. 1, a hole 1a into which a fixed sheave shaft (not shown) is inserted is formed in the axis of the movable sheave 1. A blanking step and a broaching step for forming an inner diameter groove (spline groove) A in the hole 1a are provided.
Further, the movable sheave processing method includes an inner diameter portion D, an outer diameter portion B,
The following steps for grinding the face surface C and the spline grooves A are provided. First, in the machining reference plane machining step, FIG.
As shown in (a), the boss 2 for positioning the processing jig 2
a is inserted from the hole 1a side in which the spline groove A is formed, the movable sheave 1 is positioned, and the boss outer diameter portion (▽ finished surface) E is chucked with a natural lock jig (not shown) based on the inner diameter. Thereafter, the inner diameter portion D, the hole portion 1a and the outer diameter portion B are subjected to one-chuck grinding using the respective grinding tools 3 and 4. Next, in a taper surface processing step, FIG.
As shown in (b), the outer diameter portion B machined in the machining reference surface machining step is gripped by the chuck 5 as a machining reference surface, and the face surface C is ground by the grinding tool 6 . Further, in the spline groove forming step, as shown in FIG. 2C, the inner diameter portion D is held in the same state as the outer diameter portion B is gripped by the chuck 5 as a processing reference surface in the taper surface forming step. Is ground by the grinding tool 7 . Therefore, the face surface C and the spline groove A
Are processed based on only the same processing reference plane (outer diameter portion B), so that mounting errors of the movable sheave 1 to the chuck do not accumulate and high processing accuracy can be obtained. Also, since the processing of the inner diameter part D is also performed simultaneously with the processing reference plane (outer diameter part B),
The processing accuracy of the inner diameter part D with respect to the outer diameter part B is also guaranteed. As described above, according to the present invention, since the outer diameter portion is gripped during the processing of the face surface, the processing can be performed with high load. In addition, it is possible to perform the grinding of the inner diameter portion D and the grinding of the spline groove in separate processes.
Productivity can be improved. Further, since the face surface and the spline groove are machined only on the basis of the same machining reference surface, there is no accumulation of movable sheave mounting errors on the chuck, high machining accuracy is obtained, and The runout accuracy of the movable sheave in the pulley device can be maintained at a high level.
