Therefore, as shown in FIGS. 10 and 11, the work set pin 5b should be arranged at a common position in order to share the coating jig with the wheel caps 1b and 2b of different sizes having different diameters. Can be considered. However, since the position of the work set pin 5b in this case is close to the peripheral edge of the small wheel cap 2b, when the small wheel cap 2b is placed on the coating jig, the accuracy of the coating jig, the wheel cap 2b, and the like. There is a problem in that the small wheel cap 2b cannot be reliably placed on the work set pin 5b due to variations in the accuracy of the machine and the position accuracy of the automatic machine.

The present invention has been devised in view of the above problems, and is a coating that can accommodate two types of work of different sizes, large and small, and that can surely place a small work at a predetermined position. It is an issue to be solved to provide a jig.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has two types of large and small workpieces each having a disk shape and having tapered surfaces inclined in the axial direction at least at three positions located on the same circumference of a protruding portion protruding from the lower surface thereof. A coating jig for supporting at least three work set pins that support the lower peripheral portions of the large and small types of works, and the work set pins that contact the tapered surface when the small work is placed on the work set pins. A guide ring that contacts and guides the small work to a position corresponding to the work set pin is adopted.

[0006]

[Action]

 In the coating jig of the present invention, when the small work is placed on the work set pin, the guide ring abuts the tapered surface of the small work to guide the small work to the position corresponding to the work set pin. The work is securely placed on the work set pin without displacement. As a result, it is possible to handle two types of work, large and small, having different diameters, and it is possible to reliably place a small work at a predetermined position.
