Description

Deburring mechanism for inner surface of spoke of wheel hub

technical field

The invention relates to the technical field of automobile hub processing, in particular to a deburring mechanism for the inner surface of the spoke of the hub.

Background technique

The hub is a barrel-shaped, center-mounted metal part on the axle that supports the tire inside the tire. The hub generally includes a hub body, several spokes and a rim. The hub body is provided with holes for installing the wheel shaft. The spokes are fixedly connected between the hub body and the rim to form a plurality of hub windows. The hub will inevitably produce burrs in the process of processing. For the beauty of the product, it needs to be deburred. The deburring effect of ordinary deburring machines is not ideal, and often occurs that the brush cannot be polished, which cannot meet the production requirements. If necessary, it can only be manually polished a second time, which is obviously not economical and practical, and reduces work efficiency. Therefore, it is hoped to design a special deburring equipment for the dead corner of the wheel hub processing to meet the production needs.
