Description

Technical Field

[0001] The utility model relates to a grinding device, in particular to a grinding device for a lower swing arm of an automobile. Background Art

[0002] Most automobile lower control arms are triangular in shape, also known as triangular arms, which play a certain supporting role and are connected to the tires. Holes are usually punched on the control arms to facilitate the connection of bolts or other components. After punching, there will be burrs on the edges of the holes, which need to be polished until smooth before use. Therefore, a automobile lower control arm polishing equipment is needed.

[0003] The existing automobile lower control arm grinding equipment uses a rod or cone with a grinding effect to grind the lower control arm after fixing it. However, due to the different sizes of different lower control arms, the positions of the holes that need to be deburred after installation are also different. The main body with a grinding effect cannot be flexibly adjusted, resulting in inconvenience in grinding. Utility Model Content
