Description

Shock absorber joint assembly tooling with protective structure

Technical field

The invention belongs to the technical field of assembly tooling, and specifically relates to a shock absorber joint assembly tooling with a protective structure.

Background technique

In the assembly and tightening process of motorcycle rear shock absorbers, the existing technology mainly uses manual tightening. However, since the manual torque is not fixed, the tightening torque of different people may not meet the tightening requirements, which reduces the assembly time. Under the action of cylinder pressure, the vibrator spring presses on the baffle to position the workpiece, and then use a wrench and a booster rod to tighten the locking nut and the joint. Although it can meet the needs of assembly, it is not only time-consuming and labor-intensive to operate, but also It is easy to crush the shock absorber when tightening the bolts, which will affect the efficiency and quality of the assembly to a certain extent, so the applicability and practicality are limited.
