Description

Anti-anchor clamps of twisting of flange face nut

Technical Field

The utility model belongs to the technical field of automobile part tools, and particularly relates to a flange face nut back-screwing clamp.

Background

The automobile stabilizer bar is an indispensable part in an automobile suspension system, and the connecting rod of the stabilizer bar is mainly subjected to pulling force generated when the two ends of the stabilizer bar are driven to jump due to up-and-down movement of a tire in the running process, so that after the stabilizer bar is subjected to multiple durable impacts, the connecting rod of the stabilizer bar is easy to generate fixed nut moment attenuation, and the connecting rod is broken, abnormal sound and other problems are caused. The two ends of the connecting rod of the stabilizing rod are respectively connected with the shock absorber and the transverse stabilizing rod through the ball pin sleeve, and then the fastening nut is screwed into the threaded part of the connecting rod to realize relative locking and fixing. The existing fastening device for the bolt and the nut generally fixes the nut first and then locks the nut and the nut by rotating the bolt. However, since the automobile connecting rod needs to be connected with the shock absorber or the transverse stabilizer rod in advance and then screwed into the nut for locking and fixing, the flange face nut is generally adopted as the fastening nut, six aspects of the nut can be shielded by the flange face when the flange face nut is screwed into the threaded part of the connecting pipe, the existing electric locking device cannot be adopted, and the fastening and mounting operation can only be carried out by adopting a spanner from the side face of the nut in a manual mode, so that the operation efficiency is lower.
