Problems solved by technology

[0002] In some gas spring struts or compression spring struts, since the spring needs to be repeatedly compressed and stretched to produce deformation, before the spring assembly, it is necessary to test the elastic limit, tensile limit, fatigue limit and impact toughness of the spring, so it is necessary The spring is repeatedly stretched and compressed. If the existing spring tension test device is directly stretched and compressed by a hydraulic pump or other device, the moving speed of the stretched spring will be unstable. When starting, it will suddenly The spring causes a large tensile force, which affects the test accuracy

Abstract

The invention discloses an air spring tension testing device which comprises a rack frame. A sliding rail is arranged at the bottom of the rack frame, the two sides of the sliding rail are each provided with a sliding block, hydraulic pumps are transversely installed inside the two side walls of the rack frame respectively, hydraulic rods of the hydraulic pumps are installed on the side faces of the sliding blocks on the corresponding sides, and the hydraulic pumps can push the corresponding sliding blocks to move on the sliding rail. According to the air spring tension testing device, hinge rods are arranged to be of a sleeve type structure, the lifting height and the lifting amplitude of a lifting plate can be effectively adjusted by adjusting the length of the hinge rods, the lifting speed can be adjusted through PLC control, and all the parts can be conveniently adjusted.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing and testing, and in particular relates to a gas spring tensile testing device. Background technique [0002] In some gas spring struts or compression spring struts, since the spring needs to be repeatedly compressed and stretched to produce deformation, before the spring assembly, it is necessary to test the elastic limit, tensile limit, fatigue limit and impact toughness of the spring, so it is necessary The spring is repeatedly stretched and compressed. If the existing spring tension test device is directly stretched and compressed by a hydraulic pump or other device, the moving speed of the stretched spring will be unstable. When starting, it will suddenly The spring causes a large tensile force, which affects the test accuracy. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the prior art, to provide a gas spring tensile testi...
