Description

Technical Field

[0001] The utility model belongs to the technical field of polishing devices, and in particular relates to polishing equipment for button processing. Background Art

[0002] Button shells have different models, specifications and materials. Now button shells are widely used in various mechanical equipment, elevator buttons and outdoor switches. During the processing and manufacturing process of button shells, polishing devices are needed to polish their surfaces to make the surface of the button shells smooth. At the same time, various types of wire drawing and other technologies are used to treat the surface so that the base surface of the button shell is not irritating.

[0003] The utility model with the authorization publication number CN218051998U provides a polishing device for button shell processing, which is additionally provided with a positioning mechanism, and the button shell is placed in the middle of four positioning blocks on the cross limit block, so that the four positioning blocks cover the button shell in the middle, and at the same time, a gap is left at the bottom of the button shell, so that the button shell can dissipate heat during the polishing process, thereby avoiding damage caused by excessive temperature of the button shell.

[0004] However, in the above patent, the four positioning blocks on the cross limit block do not have the function of clamping and positioning the button shell. When the button shell is polished with sandpaper, the button rotates, causing scratches between the button shell and the positioning blocks, affecting the quality of the button shell. At the same time, the gap between the button shell and the positioning blocks is small. After the polishing work of the button shell is completed, it is inconvenient for the operator to take the button shell out from between the four positioning blocks, which reduces the polishing efficiency. For this reason, we propose a polishing device for button processing. Utility Model Content
