technical field

The utility model relates to the technical field of auto parts processing, in particular to a polishing jig for auto parts.

Background technique

Auto parts are the various units that make up the whole car and a product that serves the car. Auto parts often need to use grinding jigs in the process of processing. The grinding jigs are mainly used to help control the grinding position or rotation of auto parts.

When the existing grinding jig for auto parts is actually used, it lacks the limiting structure of the auto parts, and it is inconvenient to turn over the auto parts for grinding according to actual needs.

In the publication number CN212947028U, a flip-type grinding tool for auto parts is disclosed, which includes a fixed block, and the lower ends of the fixed block near the four corners are provided with pulleys. The upper end of the side is provided with a driving mechanism, and a moving mechanism is provided in the chamber. It uses the servo motor to drive the movable block to move horizontally along the first opening under the limit action of the chute and the slider until the auto parts can be inserted into the two U-shaped blocks, and the bolts are screwed to match the two rubber products. The clamp block fixes it in the U-shaped block, which effectively limits and fixes the auto parts.

In the above design, although the auto parts can be fixed and turned over, the two sides of the parts need to be inserted into two U-shaped blocks respectively, so the surface of the parts must be covered by the U-shaped blocks. In the subsequent process of grinding the surface of the accessories, it will inevitably have an impact, so that the grinding disc is easy to grind to the U-shaped block, and part of the surface of the accessory will be blocked by the U-shaped block and cannot be polished. Therefore, a grinding tool for auto parts is designed. It is necessary to solve this problem.
