Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a burr grinding device for metal processing. Background Art

[0002] Burrs are projections or residues that are produced unintentionally during the processing process. When the cut part of the metal leaves the remaining part, it will also undergo plastic deformation, and the stretched and torn part will become a projection and remain, which is called a burr. In addition, burrs are produced even in casting, including die casting. If the burrs are left unattended, it will hinder the assembly of parts or cause the parts to not move smoothly. In particular, burrs produced in holes where liquids such as oil pass through may sometimes fall off during use, clogging other places and causing failures. In addition, because burrs are sharp spikes, they may sometimes cut the hands of operators or users.

[0003] For example, a bearing inner wall deburring and grinding device for metal processing disclosed in a Chinese patent document (publication number: CN 218017871 U) drives a grinding column to rotate through a motor so that the grinding column completely contacts the inner wall of the bearing to achieve the effect of deburring and grinding the inner wall. However, the device can only grind the inner wall of a bearing of one size and has poor adaptability. If bearings of different sizes need to be polished, multiple sets of equipment must be prepared, resulting in an increase in processing costs. Utility Model Content
