Description

[0001] The invention relates to a bearing riveting tool, in particular to an adjustable deep groove ball bearing electric riveting tool. The invention is used in the technical field of bearing assembly riveting. Background Art

[0002] Deep groove ball bearings are the most widely used rolling bearings. They are characterized by low friction resistance and high speed. Deep groove ball bearings are composed of an outer ring, an inner ring, a cage and a set of steel balls. When the deep groove ball bearing is riveted, the rivet is heated by electricity, and huge heat is instantly generated to melt the rivet and form a rivet cap through the tooling configuration. The original riveting jig cannot effectively dissipate heat after being heated at high temperatures, and the jig is deformed, which affects the riveting quality. The jig expands, making it difficult to disassemble and unable to be freely replaced. At the same time, the original structure cannot freely adjust the height of the riveted lower cavity, and cannot be universally used in a small range. Summary of the invention
