Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a bearing outer ring grinding mechanism. Background Art

[0002] The specific production process of bearings: raw materials - inner and outer ring processing, steel ball or roller processing, cage (stamping or solid) processing - bearing assembly - bearing finished product. When processing the inner and outer rings of bearings, the following process is usually included: bar - forging - turning - heat treatment - grinding - super finishing - final inspection of parts - rust prevention and storage. Among them, the bearing rings after heat treatment also need to be ground, which is an important link to ensure the accuracy of the bearing. After grinding, the production process of the bearing rings is basically completed.

[0003] The processing of the existing magnetic bearing outer ring is to fix it on the mold through magnetism after power is turned on, so that it rotates with the mold to achieve the grinding of the bearing outer ring raceway. However, for some bearing outer rings made of non-magnetic materials such as stainless steel, due to the lack of magnetism, they cannot be fixed together with the mold and driven to rotate. The operator needs to fix the bearing with a fixing part before processing can be carried out, so it needs to be improved. Utility Model Content
