[0001] The utility model relates to a shock absorber assembly device, in particular to an air spring shock absorber assembly device. Background Art

[0002] An automobile shock absorber is an important chassis part of an automobile, which plays a role in buffering and shock absorption. The automobile shock absorber is usually arranged between the suspension and the body of the automobile, and the suspension of the automobile is connected to the axle of the wheel. When the body of the automobile moves relative to the wheel, the automobile shock absorber will work and play a role in damping and shock absorption. The air spring shock absorber utilizes the elastic characteristics of air to achieve the shock absorption effect on vibration and impact. Its working principle is based on the process of compression and expansion. By repeatedly storing and releasing energy, the external vibration and impact are converted into elastic energy and gradually dissipated.

[0003] At present, the assembly process of the air spring shock absorber is divided into steps such as airbag installation, nut tightening, pressure relief valve installation, upper and lower vehicle mounting hole installation, etc., and each step is assembled separately by different equipment.
