[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. It is a modification process of the workpiece surface using polishing tools and abrasive particles or other polishing media.

[0003] When polishing annular metal products, existing clamping tools are difficult to clamp and fix the annular products, so most people use the method of holding the annular product in one hand while polishing it, which brings the problem of poor polishing effect and brings many inconveniences to the processing of annular products. Therefore, we have launched a product polishing fixture. Utility Model Content

The double-axis motor drives the two screws to rotate, and the two screws drive the rectangular rods to move in opposite directions through the threads. The rectangular rod drives the two arc-shaped clamping plates to press the inner ring of the annular product tightly. At this time, the hand-held polishing device can be used to polish the upper surface of the annular product, which is convenient for quickly clamping the annular product before polishing, and the polishing effect is good. When the other side needs to be polished, the rectangular shell is pulled toward the side away from the annular product. The rectangular shell squeezes the spring and drives multiple clamping blocks to move to the outside of the card slot.
