Description

Technical Field

[0001] The utility model relates to the technical field of arc chamfering equipment, and specifically relates to a device for arc chamfering. Background Art

[0002] To ensure the production quality of parts, chamfering operations are often required on the edges of parts. The utility model patent with the patent application number CN202222675059.3 discloses a handheld arc chamfering machine. The adjustable nut can be adjusted relative to the fixed sleeve, and the distance between the adjustable positioning inclined plane and the fixed positioning inclined plane is adjusted. During grinding, when the workpiece contacts the adjustable positioning inclined plane and the fixed positioning inclined plane, the degree of chamfer cutting is different. That is, by adjusting the distance between the adjustable positioning inclined plane and the fixed positioning inclined plane, the adjustment of the chamfer size is achieved. Moreover, after the adjustable positioning inclined plane and the fixed positioning inclined plane are worn during use, the adjustable nut can be appropriately screwed to fine-tune to ensure the accuracy of the chamfer size. According to the disclosed technical solution, when the existing arc chamfering equipment is in use, on the one hand, positioning adjustment work needs to be carried out every time chamfering operations are performed, reducing work efficiency. On the other hand, during chamfering operations, the temperature of the grinding roller is likely to rise, which is not conducive to ensuring the service life of the grinding roller, and at the same time causes dust to fly, which is not conducive to ensuring environmental hygiene.

[0003] Therefore, how to design a device for arc chamfering has become the problem to be solved currently. Summary of the Utility Model
