[0002] The wheel hub is the rotating part of the wheel core connected to the inner profile of the tire through the column, that is, the metal component mounted on the axis in the center of the tire that supports the tire. It is also called rim, steel rim, wheel, and tire bell. There are many types of wheel hubs depending on the diameter, width, molding method, and material. The surface of the wheel hub needs to be processed after manufacturing.

[0003] Existing wheel hub processing devices usually require workers to use clamps to fix the wheel hub, and also need to turn multiple bolts to fix it. Not only is the operation complicated and the work efficiency low, but manual fixation will lead to inaccurate positioning of the wheel hub center and uneven grinding when grinding the surface. Therefore, we propose a surface treatment processing machine for automobile wheel hub manufacturing. Utility Model Content
