[0019] Please refer to the attached Figure 1-Figure 5 Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0020] The utility model proposes a positioning mechanism for wheel hub processing. Before use, a group of card plates 6 are located at the closest relative distance, and a group of card plates 6 are received in the straight groove corresponding to the cross slide 10 (that is, the outer surface of a group of card plates 6 does not exceed the outer surface of the rotating shaft 3). Figure 1 As shown, at this time, the slider 13 is located at the lowest position in the cross slot 10. When using the device, the lower side of the rim of the hub 5 is covered on the outside of the shaft 3, and the hub 5 is moved downward until the upper end of the shaft 3 passes through the inner hole of the spoke plate, and the spoke plate of the hub 5 is placed on the support plate 2. After the hub 5 is placed, the hexagonal end 7 is rotated by a wrench, and the hexagonal end 7 drives the threaded rod 11 to rotate, and the threaded rod 11 drives the slider 13 to slide upward along the middle of the cross slot 10, and the slider 13 drives a group of connecting rods 12 to swing, and a group of connecting rods 12 pushes the corresponding card plate 6 to slide in the direction away from each other along the corresponding straight groove of the cross slot 10. When a group When the outer side of the clamping plate 6 fits tightly against the inner hole of the spoke plate, stop turning the wrench, adjust the speed of the motor 4 according to the processing type (painting or polishing, etc.), start the motor 4, and the motor 4 drives the corresponding pulley 8 to rotate. One pulley 8 drives another pulley 8 to rotate through the belt 9, and the other pulley 8 drives the rotating shaft 3 to rotate. The rotating shaft 3 cooperates with the support plate 2 to drive the hub 5 to rotate with the rotating shaft 3 as the center of the circle, and the outer side of the hub 5 is processed accordingly. The positioning mechanism of the device is simple, occupies a small area, greatly reduces the production cost, and is easy to disassemble and assemble. After the processing is completed, the hexagonal end 7 is rotated in the opposite direction to restore the device to its initial state.
