Description

Clamp structure for spraying automobile hub Technical Field The utility model relates to the field of wheel hub clamps, in particular to a clamp structure for spraying an automobile hub. Background Hub clamps are devices for securing and clamping hubs for machining, inspection or other operations. The hub clamp has various types and structures according to different use scenes and purposes. The hub clamp plays a critical role in the hub painting process. However, because of the variety of hub specifications, including different bolt distribution circle diameters, rim sizes, and material differences, the hub clamps need to be frequently adjusted to accommodate different hubs. Conventional wheel hub clamp adjustment mechanisms often have difficulty in fine and precise adjustment in the face of a wide variety of wheel hubs. This is mainly because the design of the clamp is often based on a certain standard or common hub specification, whereas the adjustment range and accuracy of the clamp may not meet the requirements in the face of a hub of a non-standard or special specification. The clamp adjusting mechanism is difficult to finely adjust, so that the clamp and the wheel hub are not tightly matched, and a certain looseness is generated. The loosening not only can influence the spraying effect, such as uneven coating, missing spraying and the like, but also can cause damage to the wheel hub, such as scratches, pits and the like. More seriously, the loosened clamp can fall off in the spraying process, so that potential safety hazards are caused to operators and equipment.
