Description

Technical Field

[0001] The utility model relates to the technical field of parts polishing, in particular to a curved surface polishing mechanism based on arc-shaped parts. Background Art

[0002] Common polishing equipment is used for polishing flat surfaces, and some are used for grinding and polishing curved surfaces. Polishing requires a polishing head corresponding to the curved surface. However, due to the limitation of the curved surface, the polishing efficiency is not high, especially when the curved surface of the part is adjusted to face the polishing head of the polisher. The skewness can easily cause errors in the curved surface during polishing, affecting the part itself. The existing polishing equipment only places the part under the polishing head during polishing and determines the position according to the operator's suggestions. This method is inefficient and the accuracy is affected by human factors.

[0003] Therefore, those skilled in the art provide a curved surface polishing mechanism based on arc-shaped parts to solve the problems raised in the above background technology. Utility Model Content

Since the part is fixed from three sides, the part to be polished can be fixed on the lower side of the polishing head, thereby improving the accuracy of polishing and avoiding errors that affect the part itself. After polishing is completed, the polishing head is controlled to reset, and then the movable plate 17, the positioning plate 14 and the fixed plate 16 are controlled to reset, and the first motor 6 is restarted to transport the polished parts away for collection.
