Abstract

The invention relates to a fatigue testing device, and particularly relates to an air spring fatigue testing device. The air spring fatigue testing device comprises a base and a bottom plate, whereina clamping seat is relatively fixed on the base, a clamping groove is formed in the clamping seat, a step groove is relatively formed in the clamping groove, a spring is arranged at the bottom of thestep groove, a clamping block matching the clamping groove is fixed at the bottom of the bottom plate, a slide block matching the step groove is arranged on a side face of the clamping block, a firstsupporting rod, a second supporting rod and a third supporting rod are fixed on the bottom plate, a motor is fixed at the top of the first supporting rod, the motor is connected with one end of a first connecting rod through a driving shaft, the other end of the first connecting rod is connected with one end of a second connecting rod through a rotating shaft, the other end of the second connecting rod is connected with one end of a compression bar, a first mounting seat is fixed at the other end of the compression bar, and a sleeve is arranged at the outside of the compression bar. By adoption of the technical scheme provided by the invention, the defect that a testing device capable of combining compressed tensile fatigue test with bending fatigue test is not present in the prior art canbe effectively overcome.

Description

technical field [0001] The invention relates to a fatigue test device, in particular to an air spring fatigue test device. Background technique [0002] Rubber air springs are widely used in automobiles, aviation, medical equipment, furniture, machinery manufacturing and other fields due to their good shock absorption performance. A series of inspections are required during the processing of the rubber air spring, and the factory can only leave the factory after passing the inspection. All inspection processes include the fatigue inspection of the air spring. [0003] At present, there are mainly two types of fatigue tests for air springs, one is axial compression and tension fatigue tests, and the other is bending fatigue tests. However, there is currently no test device that can combine compression-tensile fatigue testing with bending fatigue testing. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the above-mentioned shortcomings e...
