[0002] At present, a strength testing mechanism is required in the processing of fan ball bearings to test the strength of the ball bearings and check whether the bearing strength meets the production standards.

[0003] For example, a Chinese invention patent with application number CN217331977U discloses a bearing strength detection device, including a base, a detection platform is provided on the base, a frame, the frame is arranged on the base, a hydraulic telescopic rod is provided on the frame, a pressure head is provided at the lower end of the hydraulic telescopic rod, a first clamping plate and a second clamping plate, the first clamping plate and the second clamping plate are both slidably mounted on the detection platform and are radially symmetrical along the hydraulic telescopic rod, a first arc-shaped groove is provided on the first clamping plate, a second arc-shaped groove is provided on the second clamping plate, the first arc-shaped groove and the second arc-shaped groove are radially symmetrical to each other along the hydraulic telescopic rod, the inner diameter of the first arc-shaped groove and the second arc-shaped groove are equal to the outer diameter of the bearing to be tested, and a driving mechanism, the driving mechanism is connected to the first clamping plate and the second clamping plate to drive the first clamping plate and the second clamping plate to move synchronously toward or away from each other, the device can realize automatic alignment of the bearing to be tested, facilitate subsequent pressurization for strength testing, and help improve the accuracy of the detection results.

[0004] For example, a Chinese invention patent with application number CN209446401U discloses a bearing strength detection device, which includes a first rectangular plate and a bearing, the lower end of the piston rod of the cylinder is welded to the middle of the upper end surface of the first disc, a second disc is welded below the first disc through a spring, a round rod is welded to the middle of the lower end surface of the second disc, a pressure sensor is fixedly installed at the lower end of the round rod by bolts, and the lower end of the pressure sensor is fixedly connected to the top of the third disc by bolts, a round hole is vertically penetrated in the middle of the second rectangular plate, a round groove is opened at the top of the round hole, the bearing includes an inner ring, a swivel and an outer ring from the inside to the outside, the bearing is placed inside the circular groove, and the outer ring is placed on the bottom of the circular groove. In this scheme, the third disc and the inner ring are in soft contact, and the pressure of the third disc on the inner ring increases slowly, which is conducive to accurately detecting the maximum pressure that the inner ring can withstand, while providing protection for the detection device, facilitating the detection of the bearing strength, and having high detection accuracy.

[0005] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although it can quickly detect the strength of the bearing by squeezing the bearing and recording the pressure on the bearing with a pressure sensor, it can only squeeze the bearing in the axial direction and detect its strength.
