Abstract

The invention provides a wear test device, which belongs to the technical field of wear test. It includes a slider, a rocker, and a fixed groove cam. The fixed groove cam is provided with an arc-shaped upper cam groove and a lower cam groove. The left side of the fixed groove cam is provided with a left pawl, and the right side of the fixed groove cam is provided with a right The fulcrum of the lower end of the rocker is hinged on the base. The center of the upper cam groove coincides with the fulcrum of the lower end of the rocker. Slider and roller, the left end of the connecting rod is hinged to one end of the crank, the other end of the crank is connected to the swing cylinder, the abrasive wheel is rotatably set on the upper end of the rocker, the test block support can be slid left and right and set on the guide rail, the first test The block and the second test block are installed on the test block support, and one side of the test block support is provided with a driving cylinder. The invention realizes the test of the relationship between speed and wear, has simple structure and good accuracy.

Description

technical field [0001] The invention relates to the technical field of wear testing, in particular to a wear testing device. Background technique [0002] Wear is a basic type of component failure. In general terms, wear refers to the reduction in the geometric size (volume) of a component. The loss of the function specified by the original design of the component is called failure. Failure includes complete loss of original function, reduced function, serious damage or hidden danger, continued use will lose reliability, safety and security. Abrasion testing is the determination of a material's resistance to wear and tear A kind of ability material test . Through this test, the wear resistance of materials can be compared. First of all, it is necessary to consider the specific working conditions of the parts and determine the wear form, and then select the appropriate test method so that the test results are more consistent with the actual results. The wear test is d...
