Description

Technical Field

[0002] The motorcycle wheel rim is a rotating part with a bearing on each side and a bushing in the middle. After the bearings are pressed, they need to be linked without sticking or extrusion deformation. Currently, most of them are single-sided positioning and single-sided press-fitting. After completion, they are turned over for positioning and press-fitting. The process is cumbersome, and the front and back of the wheel rim are easily misplaced, which cannot ensure that the bearings are pressed in place.

[0003] After the bearing is pressed, the valve needs to be installed. There are two valves, one is a straight valve and the other is an elbow valve. The current practice is to place the wheel rim on a mounting frame, manually insert the valve, and manually push the valve into the wheel rim with a pin device.
