Abstract

The invention discloses a gas spring durability test device which comprises a support, a swing arm, a supporting table and a drive device. The swing arm is connected to the support at a first pivoting point in a pivoting mode, and the swing arm is provided with a first connecting point used for being connected with the first end of a gas spring to be tested in a pivoting mode. The supporting table is mounted on the support and provided with a second connecting point used for being connected with the second end of the gas spring to be tested in a pivoting mode. The drive device is in transmission connection with the swing arm to drive the swing arm to swing around the first pivoting point in a reciprocating mode. The gas spring durability test device can simulate actual work conditions of the gas spring in a swing mode, and therefore service life parameters of the gas spring can be measured more accurately.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a gas spring durability test device. Background technique [0002] Gas spring is an industrial accessory that can support, buffer, brake, height adjust and angle adjust. Gas springs usually include the following parts: pressure cylinder, piston rod, piston, sealing guide sleeve, filler (inert gas or oil-gas mixture), in-cylinder control elements and out-of-cylinder control elements (referring to controllable gas springs) and joints, etc. [0003] The working principle of the gas spring is to fill the closed pressure cylinder with inert gas or oil-gas mixture, so that the pressure in the cavity is several times or dozens of times higher than the atmospheric pressure, and the cross-sectional area of ​​the piston rod is smaller than that of the piston. The resulting pressure difference is used to move the piston rod. Compared with ordinary springs, gas springs have significant adv...
