Description

Novel shock absorber piston rod disassembly and assembly fixture

Technical Field

The utility model relates to the technical field of manufacturing of mechanical installation tools, in particular to a novel disassembly and assembly clamp for a piston rod of a shock absorber.

Background

Shock absorbers (absorbers) are used to suppress the shock and impact from road surface when the spring bounces after absorbing the shock. The damping device is widely used for automobiles, and is used for accelerating the damping of the vibration of the frames and the automobile bodies so as to improve the running smoothness of the automobiles.

While the shock absorbing spring can filter the shock of road surface when passing over uneven road surface, the spring itself can reciprocate, and the shock absorber is used to restrain the spring from jumping. The shock absorber is too soft, the automobile body will jump from top to bottom, and too hard of shock absorber will bring too big resistance, prevents the spring normal operating. In retrofitting a suspension system, a hard shock absorber is associated with a hard spring, and the stiffness of the spring is closely related to the vehicle weight, so that a heavier vehicle typically employs a harder shock absorber. And the device is connected with the shock-inducing crankshaft and is used for countering torsional shock of the crankshaft.

Because the shock absorber has high use strength and severe use environment, the shock absorber of the locomotive needs to be frequently maintained. The damper needs to be disassembled and assembled during routine maintenance. The shock absorber piston rod is difficult to disassemble and assemble by adopting a traditional tool due to special structure, and some clamps can also complete related work, but the clamp damages the outer surface of the piston rod in the clamping process due to lower fitting degree of the clamp and the shock absorber piston rod.
