Automobile locknut and machining process thereof

Abstract

The invention discloses an automobile locknut and a machining process thereof. The automobile locknut has the advantages of being good in anti-loosening effect and easy to disassemble, the machining process is efficient and environmentally friendly, the needed performance requirement can be met, the automobile locknut is characterized by comprising an inner-layer nut body and an outer-layer nut body, a first inner threaded hole is formed in the center of the inner-layer nut body, the inner-layer nut body is cylindrical, a cavity is formed in one end of the outer-layer nut body, the inner-layernut body is installed in the cavity, a second inner threaded hole is formed in the other end of the outer-layer nut body, the inner diameter of the first inner threaded hole is the same as that of the second inner threaded hole, and a clearance compensation assembly is further arranged in the cavity and comprises a metal shell and an expansion rubber. The automobile locknut is applicable to the technical field of nuts.

Description

technical field [0001] The invention belongs to the technical field of nuts, in particular to an automobile anti-loosening nut and its processing technology. Background technique [0002] Automobile anti-loosening nuts are common fasteners in automobiles. In order to avoid the phenomenon of loosening and fastening failure of screws and nuts during use, the industry has made a lot of improvements to the anti-loosening functions of screws and nuts; traditional anti-loosening There are two types of anti-loosening measures for nuts, one is the use of auxiliary washers, such as spring washers, anti-loosening washers, etc., the effect of this method is not obvious, especially in severe vibration conditions, the anti-loosening is not reliable; the other is Endowing the nut with its own anti-loosening function, a variety of anti-loosening nuts have emerged. In summary, these anti-loosening nuts use two methods to enhance the anti-loosening ability. One is to change the structure of ...
