Design and Development of an Automatic Oil Injection Fixture Device for Hydraulic Shock Absorbers

Abstract

As a critical component of rail trains, the hydraulic shock absorber currently relies on manual operation for the oil filling process, which presents issues such as low efficiency and high labor intensity. This paper adopts an integrated approach of digital modeling design and verification analysis to develop a fixture device for the oil filling process in the hydraulic shock absorber assembly line. This device, operated via a collaborative robot,s enables full automation of the entire process, including feature recognition, oil gun docking, and piston rod grasping. It replaces manual labor and offers advantages such as simple operation, high stability, and a high degree of automation.
