[0002] The sleeve is a cylindrical mechanical part that is sleeved on the rotating shaft and is a component of the sliding bearing. Generally speaking, the sleeve and the bearing seat use interference fit, and the shaft uses clearance fit. After the CNC lathe completes the processing of the sleeve, the sleeve size needs to be tested. Usually people will use a round iron ball for testing. First, people place the sleeve under the testing mechanism, and then place the testing ball on the sleeve. Then people will start the testing mechanism to squeeze the testing ball. If the testing ball passes through the sleeve, the sleeve is qualified. If the testing ball is stuck in the sleeve, it is unqualified. However, this requires people to manually place the testing ball on the sleeve continuously, which is inefficient. After the test is completed, the sleeve also needs to be manually removed. Therefore, we need to develop a sleeve auxiliary detection device that does not require people to manually place the testing ball on the sleeve, has high detection efficiency, and does not require manual removal of the sleeve.
