Abstract

The invention discloses an air spring bending fatigue testing machine, which is characterized in that it includes a rotating shaft and a frame for fixing the air spring, at least one connecting rod parallel to the axial direction of the air spring is fixedly arranged on the frame, and the rotating shaft is connected On the connecting rod, the rotating shaft is fixedly connected with the center point of the end of the air spring and is perpendicular to the axial direction of the air spring. The rotating shaft is connected with a rotating shaft swing driving mechanism to drive the air spring to bend; The bending fatigue test of the spring is simple in structure, easy to use and low in cost; in addition, since the swing angle adjustment mechanism is set between the rocker and the turntable, the swing range of the swing rod can be adjusted to meet the requirements of different bending degrees of the air spring; And because the distance adjustment mechanism is arranged between the rotating shaft and the frame, the bending fatigue test of air springs with different lengths can be realized by changing the distance between the rotating shaft and the air spring installation surface.

Description

technical field [0001] The invention relates to an air spring detection device, in particular to an air spring bending fatigue testing machine. 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. 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 radial torsional fatigue tests. When the air spring needs to be tested for bending fatigue, there is currently no special equipment for testing it, and at present, the bending fatigue test for air springs is basically not performed.
