Description

Technical Field

[0001] The utility model relates to the technical field of machine wear detection, in particular to a bushing rotation wear testing device. Background Art

[0002] A bushing is a ring that acts as a cushion. In moving parts, long-term friction causes wear of parts. When the clearance between the shaft and the hole wears to a certain extent, the parts must be replaced. Therefore, when designing, the designer chooses materials with lower hardness and better wear resistance as the sleeve or bushing, which can reduce the wear of the shaft and the seat. When the sleeve or bushing is worn to a certain extent, it can be replaced, which can save the cost of replacing the shaft or seat.

[0003] The utility model patent application document with publication number "CN219870840U" discloses a bushing continuous rotation wear detection device, which includes support legs, a workbench, a wear device, a clamping device and a detection device. The technical scheme sets up a detection device. Before the device is used, a laser detector is used to detect the distance between it and each point of the bushing. After the device is used, the laser detector is used to detect the distance between each point of the bushing and the distance detected before the device is used, and a comparison is made to understand the degree of wear of the bushing.

[0004] The bushing continuous rotation wear detection device disclosed in the above document has the following defects: after long-term use, the grinding block of this technical solution reaches a certain wear and cannot be used, and it is inconvenient to replace, and the practicality is relatively low.

[0005] It can be seen from this that the existing bushing continuous rotation wear detection device does not have a good replacement structure, and it is necessary to improve the existing deficiencies and provide a bushing rotation wear test device. Utility Model Content
