Air pressure dynamic load testing system capable of achieving end face self-cleaning for driving axle assembly

Abstract

The invention discloses an air pressure dynamic load testing system capable of achieving end face self-cleaning for a driving axle assembly. The air pressure dynamic load testing system structurally comprises an air inflation device, a driving axle sealing device, a driving air pump, an equipment supporting frame, a moving wheel stand and a driving axle fixing frame, the equipment supporting frameis horizontally mounted on the ground, the moving wheel stand and the equipment supporting frame are fixed together through bolts, and the driving axle fixing frame is horizontally mounted at the left end and the right end of the upper surface of the equipment supporting frame. The air pressure dynamic load testing system is provided with a first cleaning device and a second cleaning device, thuswhen an air inflation sealing head is attached to a driving axle housing, dust particles on the junction of the end face of the driving axle housing and the air inflation sealing head can be effectively cleared away, the situations that due to chippings, gaps exist in a detection head and the surface of a driving axle, and leakage occurs during air inflation of the axle housing are avoided, and the accuracy of the air tightness detection result of the driving axle housing is effectively improved.

Description

technical field [0001] The invention relates to pneumatic equipment, in particular to a pneumatic dynamic load testing system for a self-cleaning drive axle assembly. Background technique [0002] With the improvement of science and technology, the manufacturing level of automobiles is also rising day by day. The automobile drive axle is one of the important parts of the automobile. The drive axle shell is formed by welding. In order to avoid defects such as cracks and pores in the welded seam, The oil leakage of the drive axle assembly occurred. Therefore, the sealing of the axle housing must be tested during production. However, the current technical considerations are not perfect, and it has the following disadvantages: During the welding production process of the drive axle housing, there are residues on the surface of the axle housing. A large amount of dust and other processing debris. During the testing process, the test bench is directly bonded to the surface of the ...

[0002] With the improvement of science and technology, the manufacturing level of automobiles is also rising day by day. The automobile drive axle is one of the important parts of the automobile. The drive axle shell is formed by welding. In order to avoid defects such as cracks and pores in the welded seam, The oil leakage of the drive axle assembly occurred. Therefore, the sealing of the axle housing must be tested during production. However, the current technical considerations are not perfect, and it has the following disadvantages: During the welding production process of the drive axle housing, there are residues on the surface of the axle housing. A large amount of dust and other processing debris. During the testing process, the test bench is directly bonded to the surface of the axle housing and then inflated for testing. When the testing head is attached to the surface of the driving axle, the debris will cause a gap between the testing head and the surface of the driving axle. , which in turn leads to leakage when the axle housing is inflated, resulting in inaccurate air tightness test results
