Description

Technical Field

[0001] The invention relates to the technical field of parts polishing, and in particular to a polishing device for automobile parts production and a polishing process thereof. Background Art

[0002] In the production process of automobile parts, polishing is a crucial link, which can not only improve the appearance quality of parts, but also enhance their durability and performance. Especially in the production process of automobile brake discs, usually after the brake disc body is completed, the brake disc body is polished and polished using polishing equipment. On the one hand, it is used to reduce the friction noise during braking and improve the braking performance, and on the other hand, it is used to increase its aesthetics and improve product quality. However, there are still some problems with the existing polishing equipment during actual use. For example, in the process of polishing the brake disc, in order to ensure the aesthetics and smoothness of the brake disc, the existing polishing equipment generally adopts double-sided grinding. After polishing one side of the brake disc, the existing polishing equipment needs to manually turn the brake disc over and clamp it to complete the double-sided polishing. In the process of manual turning over, a lot of time will be wasted, which will affect the polishing efficiency.

The patent application document controls the start of the motor 2 to drive the rotating shaft to rotate inside the column 2, and can drive the entire clamping assembly to flip, until the other side of the brake disc clamped inside the clamping assembly faces upward, and the automatic flipping of the brake disc can be completed.

[0004] In the related art, when polishing a large number of brake discs, since the brake discs themselves are in the form of thin sheets, the brake discs are easily stacked during polishing, resulting in uneven polishing, and the edges of the hollow parts on the brake discs are difficult to effectively polish. Summary of the invention
