Stress testing device and method for automobile suspension control arm bushing reinforcing member

Abstract

The invention discloses a stress testing device and method for an automobile suspension control arm bushing reinforcing member. The stress testing device comprises a test bench, wherein two limiting grooves are formed in the top surface of the test bench; movable holes are formed in the top surface of the test bench and are located just below the limiting grooves; a slide way is formed in the backsurface of the test bench; a slide rod is fixed in the slide way; a slide sleeve sleeves an outer wall of the slide rod; a translation motor is mounted in the slide sleeve; a translation screw rod isfixed at a power output end of the translation motor; a translation rack is arranged on the top surface of the slide rod; a bearing barrel is fixed on the top surface of the slide sleeve; a hoistingmotor is mounted in the bearing barrel; a slide groove is formed in an inner wall of one side, close to the test bench, of the bearing barrel; a slide plate is mounted in the slide groove; and a bearing rod is fixed at one side, far away from the hoisting screw rod, of the slide plate. All the devices are matched to use, so that a stressed force point of the reinforcing member is overlapped with the center of the reinforcing member when the reinforcing member is subjected to a stress test, and furthermore, a measurement result is more accurate; and potential safety hazards caused by the fact that the reinforcing member is broken can be prevented.

Description

technical field [0001] The invention relates to the related technical field of a stress test device for a bush reinforcement, in particular to a stress test device and a test method for a bush reinforcement of an automobile suspension control arm. Background technique [0002] The stress test of the bushing reinforcement can predict the use of the reinforcement to a certain extent, which can effectively reduce safety hazards and improve the manufacturing process. However, the stress on the reinforcement during the stress test is often not at its center, making There is a certain error in the measurement results. When the stress test is carried out on the reinforcement, the pressure on it continues to increase. When the pressure reaches a certain value, the reinforcement is prone to breakage, and the broken reinforcement is easy to pop out of the test platform. There is a certain security risks. Contents of the invention [0003] The purpose of the present invention is to ...
