Description

Technical Field

[0001] The utility model relates to the technical field of wear detection, in particular to a wear detection device for electric hardware. Background Art

[0002] While filing this application, the applicant searched and discovered a Chinese patent application numbered "201921780369.3" that discloses a "device for testing the wear resistance of electrical hardware." The patent primarily comprises a test platform with a groove on its upper surface and brackets welded tightly to both sides of the upper surface. A cylinder is mounted on the top plate of the two brackets, and a base plate is positioned between the two brackets. The base plate is equipped with a motor, and a grinding wheel is mounted on one end of the motor's output end that passes through the base plate. In this device, when the cylinder's output end extends, a pressure rod pushes the motor downward, causing the base plate to move downward, allowing the grinding wheel to extend into the groove to perform a wear test on the hardware. The greater the cylinder's output end extends, the greater the pressure applied by the grinding wheel on the hardware surface. Conversely, the smaller the cylinder's output end extends, the less pressure applied by the grinding wheel on the hardware surface. This allows the wear resistance test of the hardware to be completed. However, this device cannot perform wear testing on the back of the hardware, which could affect the accuracy of the test results or increase the cost of testing. To this end, we propose an electrical hardware wear detection device to solve the above problems. Utility Model Content

In Example 2, a cylinder, a motor and a grinding wheel are provided, which solves the problem that the anti-wear detection device of the electric hardware is not convenient to adjust the surface pressure of the grinding wheel and the hardware during the detection process. However, in Example 1, the hardware can be rotated on the disc after being fixed by providing a disc and a column, which solves the problem that the hardware cannot rotate after being fixed, resulting in only a part of the surface of the hardware being tested, resulting in inaccurate structure. In Example 2, the electric hardware to be tested is placed in the groove, and the device cannot perform wear detection on the back of the hardware, which will affect the accuracy of the test results.
