Abstract

A testing device for detecting impact friction abrasion of a workpiece comprises a rack and a work chamber on the rack. A sand leaking plate used for recycling abrasives is arranged on the bottom face of a box body of the work chamber. A conical transition cavity is formed below the sand leaking plate. The conical transition cavity is communicated with an abrasive storage cavity, and discharged materials of the abrasive storage cavity are driven to be conveyed to a material conveying pipe through compressed air. An abrasive output opening and a clamp and a sample clamp of the abrasive output opening are arranged in the box body. The sample clamp is mounted on a nonflexible adjusting device, and the angle of a sample can be adjusted through the nonflexible adjusting device. The testing device further comprises a dust collector used for dedusting the inside of the work chamber. The testing device for detecting the impact friction abrasion of the workpiece is simple and reliable in sample operation, compact in structure, suitable for samples of different specifications, and capable of enabling the positions of the samples to be adjusted so that various working conditions can be simulated. An abrasive nozzle can also be firmly clamped, and the impacting angle to the samples can be adjusted. In addition, the abrasives can be used in a recycling mode, and the abrasives are saved.

Description

technical field [0001] The invention relates to a friction and wear test device, in particular to a test device for detecting the impact friction and wear of workpieces. Background technique [0002] As we all know, friction and wear is a basic type of component failure, and it is also an important reason for the inefficiency of mechanical equipment. Friction and wear are not only the reason for the low efficiency of mechanical equipment, but also the main form of equipment failure. The wear of workpieces has become an important reason for the short life of the machine. A large part of the world's one-time energy consumption is consumed on friction and wear. Friction and wear testing machine is an experimental equipment for evaluating various anti-wear properties and calculating friction coefficient. At present, the test device for testing impact friction and wear is relatively simple. SUMMARY OF THE INVENTION [0003] In order to overcome the shortcomings of the above-m...
