The rotating portion 41 is a member that can rotate around the rotating shaft RA1. A base 30 to which the first processed portion 10 and the second processed portion 20 are attached is installed in the rotating portion 41 and holds them.

The positioning portion 42 is a protruding member that fits into the positioning hole 31 of the substrate 30. Specific examples of the positioning unit 42 include a protruding member such as a pin. The positioning unit 42 can move in the direction of the rotation axis RA1. When the first processed portion 10, the second processed portion 20, and the base 30 are installed in the rotating portion 41 and these are rotated to align the positions of the positioning portion 42 and the positioning hole 31, the positioning portion 42 becomes the positioning hole 31. Fit. As a result, the substrate 30 can be positioned with respect to the holding portion 40.

In the present embodiment, the phase matching unit 43 does not rotate about the rotation axis RA1.

As shown in FIGS. 6 and 7, the positioning portion 42 and the phase matching portion 43 are arranged on the vertical line VL passing through the rotation center C. Therefore, when the positioning portion 42 of the holding portion 40 is fitted into the positioning hole 31 of the base 30, the positioning hole 31 of the base 30 is arranged on the vertical line VL. As described above, the positioning hole 31 of the substrate 30 and one processed tooth of the first processed portion 10 are arranged on a straight line L passing through the rotation center C. Therefore, by fitting the positioning portion 42 of the holding portion 40 into the positioning hole 31 of the base 30, the positioning hole 31 of the base 30 and one machined tooth of the first machined portion 10 are arranged on the vertical line VL. Tooth. That is, the phase matching portion 43 of the holding portion 40 and one processed tooth of the first processed portion 10 are arranged on the vertical line VL. Therefore, by aligning the position of the phase matching portion 43 of the holding portion 40 with the position of the groove portion of the tooth of the machining target portion, the phase of one of the machined teeth of the first machining portion 10 and the tooth of the machining target portion are matched. be able to.

Even after the second machined portion 20 is attached to the substrate 30, the second machined portion 20 is tightened so that it can rotate a predetermined angle. Therefore, the position of the machined tooth of the second machined portion 20 can be adjusted by rotating the second machined portion 20. As a result, the phases of the processed teeth of the second processed portion 20 and the teeth of the processed target portion can be matched.

FIG. 8 is a diagram showing a processing method of a processing object using the processing apparatus 1. When machining an object to be machined by using the machining device 1, the tip portion of one machined tooth of the machining portions 10 and 20 of the machining apparatus 1 and the phase matching portion 43 are aligned with each other. Specifically, on the side where the phase matching portion 43 exists, the tip portion of one machined tooth of the processed portions 10 and 20 and the phase matching portion 43 are placed on a straight line L (FIG. 2) and a vertical line VL (FIG. 7). Place in. As a result, the tip portion of the machined tooth and the phase matching portion 43 are aligned on the straight line L and the vertical line VL.

In the step shown in step S101, as shown in FIG. 9, the phase matching portion 43 is inserted into one tooth groove of the workpiece 50. When the phase matching portion 43 is securely inserted into the tooth groove of the machined object 50, the phase of the teeth of the machined object 50 and the phase of the machined teeth of the machined parts 10 and 20 are in the same state. When the phase matching portion 43 is securely inserted into the tooth groove of the object to be machined 50, the step of step S102 can be omitted.

The step shown in step S102 is when the phase matching portion 43 is not securely inserted into the tooth groove of the machining target object 50 (for example, when the phase matching portion 43 is in contact with the teeth of the machining target object 50). Will be executed. In the step shown in step S102, the machining object 50 is rotated and stopped around the rotation shaft RA2 of the machining object 50 parallel to the rotary shaft RA1. The rotation angle of the object to be machined 50 is preferably within an angle defined by two adjacent tooth grooves of the object to be machined 50 and the center of rotation of the object to be machined 50. In other words, the tooth groove of the work object 50 is moved in the circumferential direction according to the distance between two adjacent tooth grooves of the work object 50. For example, when the distance between two adjacent tooth grooves is 10 mm, the tooth grooves of the object to be machined 50 are moved by about 10 mm in the circumferential direction. Then, when the phase matching portion 43 is surely inserted into the tooth groove of the machining target object 50 by rotating the machining target object 50, the rotation of the machining target object 50 is stopped. As a result, the phase of the tooth of the object to be machined 50 and the phase of the machined tooth of the machined portions 10 and 20 can be matched.

In the step shown in step S103, the machined object 50 is moved in the direction of the rotation axis RA2 as shown in FIG. 9 in a state where the phase of the teeth of the machined object 50 and the phase of the machined teeth of the machined portions 10 and 20 match. By moving the tooth, the tooth of the object to be machined 50 and the machined tooth of the machined portion 10 and / or the machined portion 20 are meshed with each other. In the step shown in step S104, the processing apparatus 1 is operated to start processing the processing object 50.

In the processing method of the processing object 50 using the processing apparatus 1 described above, the phase matching portion 43 is formed in a state where the tip portion of one machined tooth of the processed portions 10 and 20 and the phase matching portion 43 are aligned with each other. , It is inserted into one tooth groove of the object to be machined 50, and the phase of the tooth of the object to be machined 50 and the phase of the machined tooth are matched. Then, the teeth of the object to be machined 50 and the teeth to be machined are meshed with each other in a state where the phase of the teeth of the object to be machined 50 and the phase of the processed teeth are matched.

As a result, it is possible to prevent these teeth from colliding with each other when the teeth of the object to be processed 50 and the processed teeth of the processed portions 10 and 20 are engaged with each other. Can be meshed smoothly.

The present invention is not limited to the above-described embodiment, and can be appropriately modified without departing from the spirit of the present invention.
