AI Technical Summary

Technical Problem

Existing hydraulic damper testing equipment is expensive and inefficient, and manual testing methods have large errors, making it difficult to achieve high-precision piston rod circumferential runout detection.

Method used

The mechanical testing device includes a V-shaped support group, a clamping group, a linkage structure, and a leveling adjustment group. The adjustable V-shaped support group and clamping group can accommodate hydraulic buffers of different specifications. The spring clamping method avoids damage to the workpiece surface, and the linkage structure facilitates workpiece installation and dial indicator leveling to improve testing accuracy and efficiency.

Benefits of technology

It achieves low-cost, high-precision hydraulic buffer detection, adapts to different specifications, avoids workpiece damage, and improves detection efficiency.

Abstract

This application discloses a testing device for the production of hydraulic shock absorbers, including a base plate and two V-shaped support groups symmetrically arranged on the base plate. Each V-shaped support group has a clamping assembly, and a linkage structure is provided between the two clamping assemblies. A dial indicator is installed on the front side of each V-shaped support group. Each V-shaped support group includes a V-shaped plate and support rollers, with two support rollers rotatably connected to the V-shaped plate. One of the V-shaped support groups has a drive mechanism for rotating the support rollers. This application adopts a purely mechanical structure, is low in cost, easy to operate, and can quickly and accurately detect the radial and end-face runout of the piston rod, making it suitable for the production testing of hydraulic shock absorbers of various specifications.
