Description

Spring press-fitting machine

Technical Field

The utility model relates to a press-fitting machine, in particular to a spring press-fitting machine, and belongs to the technical field of spring damper assembly.

Background

The shock absorber is mainly used for inhibiting vibration and impact from the road surface when the spring rebounds after absorbing the vibration. 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. In order to reduce vibration and impact of road surface to vehicle, the spring is needed to absorb the energy of vibration and impact, the spring is an energy storage element in the suspension, the working principle of the hydraulic shock absorber is that when the vehicle frame and the vehicle axle do reciprocating relative motion, and the piston reciprocates in the cylinder barrel, oil in the shock absorber shell repeatedly flows into another inner cavity from one inner cavity through a plurality of narrow holes, at the moment, friction between the hole wall and the oil and friction in liquid molecules form damping force on vibration, so that the vibration energy of the vehicle body and the vehicle frame is converted into heat energy, absorbed by the oil and the shock absorber shell and then dispersed into the atmosphere.

In the process of assembling the spring damper, the hydraulic cylinder is required to drive the piston rod to pass through the upper spring seat, however, in the actual operation process, the piston rod is easy to deflect and difficult to pass through the hole, if the piston rod cannot pass through the hole in the upper spring plate in time during assembly, the piston rod is influenced by the pressure of the air cylinder, the piston end impacts the bottom valve, the bottom valve assembly can be invalid, meanwhile, the damper is required to be held by the hand in the spring pressing process, the piston rod of the damper is kept at the center of the hole in the upper spring plate, the piston rod is difficult to align once, and if the spring is ejected out, the spring is easy to hurt hands, and potential safety hazards exist.
