Description

[0002] Rubber seals are an important component used to prevent liquid or gas leakage in mechanical devices. They are usually made of rubber or similar materials and have good elasticity and sealing properties. They are widely used in industrial and mechanical equipment, such as automobiles, aerospace, engineering machinery, pipeline systems, etc. Rubber seals usually work in high friction, high pressure or high temperature environments, so their wear resistance directly affects their service life and performance stability. Through wear resistance testing, the degree of wear of the seal during long-term use can be evaluated, so as to predict its life and performance degradation. Through wear resistance testing, the influence of different materials and design schemes on the wear resistance of the seal can be evaluated, which helps to optimize material selection and design parameters and reduce frequent replacement and maintenance costs.

When the first motor 202 works, it can drive the adjustment plate 203 to rotate. Another adjustment plate 203 is fixed below the adjustment plate 203. The two adjustment plates 203 are staggered and fixed. The adjustment plate 203 is fixed to the rotating table 208 through the connecting column 204. When the first motor 202 drives the adjustment plate 203 to rotate, The connecting column 204 can be used to drive the rotating table 208 to swing back and forth. At the same time, the second motor 206 can drive the U-shaped frame 207 to rotate when it is working, and then drive the rotating table 208 to swing left and right. Through the cooperation of the two rotatable parts, the rotating table 208 can be rotated in all directions. The rotating table 208 is connected to the grinding sheet 4 through a vertical rod, and then the grinding sheet 4 can be driven to rotate when the adjusting mechanism 2 is working, so that the rubber seal to be inspected can be polished at multiple angles.
