Technical Field

[0001] The utility model relates to the field of automobile component fixing, in particular to a rotary clamping tool for automobile components. Background Art

[0002] As the foundation of the automotive industry, auto parts are a necessary factor in supporting the sustainable and healthy development of the automotive industry. In particular, the current vigorous and full-scale independent development and innovation in the automotive industry requires a strong parts system to support it.

[0003] Wheels and tires are indispensable among automotive parts. During the production process, these automotive parts need to be deburred and polished. These treatments usually require professional technicians to use polishing machines to achieve. In order to ensure the stability of the parts during the polishing work, it is necessary to use a clamping tool to clamp the parts and then polish them. However, most of the existing clamping tools use two cylinders to drive the clamping plates to clamp and fix the two sides of the parts. If it is necessary to polish other sides of the parts during the processing, the parts must be removed from the clamping tool, and then the position of the parts is adjusted, and finally the clamping tool is used again to clamp the parts, which greatly affects the work efficiency.

[0004] Therefore, it is necessary to invent a rotary clamping fixture for automobile parts. Utility Model Content
