As the indispensable key connecting piece of many mechanical equipment, the quality of the sleeve is directly related to the performance and service life of the whole mechanical system. Hardness, as one of the core indicators of the quality of the sleeve, plays an important role in the performance of the sleeve under pressure, friction and various complex working conditions.

[0003] At present, the common bearing roller hardness detection equipment mostly adopts the traditional fixed clamping and single-point detection structure. Usually, a simple clamp is used to fix the bearing roller on the detection table, and the detection probe can only test the hardness of the bearing roller in a single direction at a fixed position. Because the detection angle of the bearing roller cannot be flexibly adjusted, the detection range is limited. When different parts such as the side surface or the inner arc surface of the bearing roller need to be detected, the clamp needs to be loosened first, then the position of the bearing roller needs to be adjusted again, and then the detection is carried out after the clamp is tightened. Moreover, it is difficult to ensure that the position accuracy of the bearing roller is completely consistent every time the clamp is tightened again, which introduces uncertainty to the detection result.
