Description

Technical Field

[0001] The present application relates to the technical field of bearing production equipment, and in particular to an outer ring grinding device for producing spherical bearings. Background Art

[0002] Bearings are important basic components of various types of mechanical equipment. They are components that fix and reduce the load friction coefficient during mechanical transmission. In other words, when other parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies.

[0003] At present, a Chinese patent announcement with announcement number CN216151889U discloses an outer ring grinding device for spherical bearing production, which includes two brackets, top plates are fixedly installed at the top ends of the two brackets, a hydraulic cylinder is fixedly installed at the middle part of the bottom end of the top plate, an output end of the hydraulic cylinder is fixedly installed at a chassis, a fixed plate is fixedly installed at the bottom end of the chassis, and a grinding piece is movably installed at the bottom end of the fixed plate. The hydraulic cylinder drives the fixed plate to contract while driving the connecting rod to rise, so that the block at the bottom of the connecting rod lifts one end of the grinding table during the rising process, so that the outer ring of the bearing on the grinding table slides into the collection box, thereby improving the grinding efficiency and eliminating the need for manual collection, reducing the labor of workers. While grinding, the dust suction fan is started to absorb the dust generated by grinding into the dust collection box through the dust suction hood for collection, which can effectively adjust the diameter of the clamping device and avoid damage to the on-site environment.

[0004] In actual use, it is found that the existing equipment clamps and fixes the outer ring of the bearing, which limits the range of grinding the outer ring of the bearing, making it inconvenient to grind the outer ring of the bearing in all directions, which in turn leads to the problem of inconvenience in use. Therefore, we propose an outer ring grinding device for spherical bearing production to solve the above problem. Utility Model Content
