Flexural fatigue inspection machine of air spring

Abstract

The present invention discloses a flexural fatigue inspection machine of an air spring. The flexural fatigue inspection machine of the air spring is characterized by comprising a spindle, a frame for fixing the air spring, and at least one connecting rod which is axially parallel to the air spring and is fixedly installed on the frame; the spindle is coupled on the connecting rod, is fixedly connected with the central point of the end of the air spring, and is vertical to the axial direction of the air spring; and a spindle swing driving mechanism is connected on the spindle to drive the air spring to bend. The flexural fatigue inspection machine of the air spring has the advantages of capacity of achieving the flexural fatigue inspection of the air spring through the flexural fatigue inspection machine provided by the invention, simple structure, easy operation and low cost; moreover, the amplitude of swing of a swing rod may be regulated through a swing angle regulating mechanism arranged between the swing rod and a rotary table so as to satisfy the requirement of different degrees of bend of the air spring, and the flexural fatigue inspections of air springs with different lengths are realized through a distance regulating mechanism arranged between the spindle and the frame by means of changing the distances between the spindle and the fitting surfaces of the air springs.

Description

technical field [0001] The invention relates to a detection device for an air spring, in particular to an air spring bending fatigue testing machine. Background technique [0002] Rubber air springs are widely used in automobile, 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 rubber air springs. Only after passing the inspection can they leave the factory. All inspection processes include fatigue inspection of air springs. At present, there are mainly two kinds of fatigue inspections for air springs, one is axial compression and tensile fatigue inspection, and the other is radial torsional fatigue inspection. When the air spring needs to be tested for bending fatigue, there is currently no special equipment to test it, and the bending fatigue test of the air spring is basically not performed at present. SUMMARY OF THE INVENTION ...
