Description

Technical Field

[0001] This utility model relates to the field of wheel hub processing technology, specifically to a wheel rim processing outer surface treatment device. Background Technology

[0002] The wheel hub is the component at the center of a car wheel where the axle is mounted. Its main function is to support the tire and connect the wheel to the axle. Its performance directly affects the driving safety and stability of the vehicle. The outer surface treatment of the wheel hub is not only related to aesthetics, but also to improving durability. Common treatment methods include electroplating, spraying, grinding and polishing. These treatments can effectively resist external corrosion and wear, and extend the service life of the wheel hub.

[0050] When performing grinding and polishing on the outer surface of the wheel hub, the wheel hub is first placed on the insertion limit rod 23. After confirming that the wheel hub cannot move easily, the grinding and polishing operation can be carried out. When it is necessary to rotate the wheel hub, the foot drives the foot drive plate 341 to rotate clockwise. The clockwise rotation of the foot drive plate 341 will drive the locking rod 31 to move downward through the connecting rope 342. When the locking rod 31 is completely disengaged from the locking hole, the T-shaped turntable 21 and the wheel hub can be rotated. When the wheel hub is rotated to the appropriate angle, the force applied to the foot drive plate 341 is removed. The locking rod 31 will automatically perform a reset movement under the action of the return spring 33. When the locking rod 31 is inserted into the corresponding locking hole, the locking work of the T-shaped turntable 21 and the wheel hub is completed again, which improves the stability of the wheel hub during the grinding and polishing process and ensures the grinding accuracy.
