[0011] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0012] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0013] like Figure 1 As shown, this utility model provides a bearing flexibility testing device, including a testing station 1 for placing a bearing 13. The testing station 1 is part of a conveyor line. A lifting hole 2 is provided in the middle of the testing station 1. The diameter of the lifting hole 2 is larger than the outer diameter of the bearing inner ring and smaller than the inner diameter of the bearing outer ring. A lifting shaft 3 is provided in the lifting hole 2. The upper end of the lifting shaft 3 is provided with a lifting platform 4 for positioning the bearing inner ring and supporting the bearing 13. The lower end of the lifting shaft 3 is connected to a lifting drive mechanism, which is a lifting drive cylinder 5. The output end of the lifting drive cylinder 5 is connected to the lower end of the lifting shaft 3. The lifting drive mechanism drives the lifting shaft 3 to move up and down in the lifting hole 2. A stand 6 is provided next to the testing station 1, and the stand is equipped with... A transverse frame 7, driven by a transverse drive mechanism (a transverse drive cylinder 8), moves left and right. The output end of the transverse drive cylinder 8 is connected to the transverse frame 7. A vertical rotating shaft 9 is provided on the transverse frame 7. The lower end of the rotating shaft 9 is provided with a drive roller 10 that can contact the outer ring of the bearing. The upper end of the rotating shaft 9 is connected to a rotary drive mechanism (a rotary drive motor 11). The output end of the rotary drive motor 11 is connected to the upper end of the rotating shaft 9. The rotary drive mechanism drives the drive roller 10 to rotate through the rotating shaft 9. An optical fiber counting sensor 12 is provided above the detection station 1. The optical fiber counting sensor 12 is aligned with any ball in the bearing and is used to detect the number of rotations of the bearing 13 when the drive roller 10 drives the outer ring of the bearing to rotate.
[0014] In use, initially, the upper end of the lifting platform 4 of the lifting shaft 3 is flush with the testing station 1. Then, the bearing 13 to be tested is conveyed to the testing station 1 by the conveyor line. The hole of the inner ring of the bearing 13 aligns with the lifting hole 2. Then, the lifting drive cylinder 5 drives the lifting shaft 3 to rise. The lifting platform 4 on the lifting shaft 3 positions the inner ring of the bearing and lifts the bearing 13 to be tested upwards. After the lifting shaft 3 reaches its position, it stops. Then, the transverse drive cylinder 8 drives the transverse frame 7 to move to the right. The rotating shaft 9, the rotary drive motor 11, and the... The drive roller 10 moves accordingly, making tight contact with the outer ring of the bearing 13 under test. Then, the rotation drive motor 11 drives the drive roller 10 to rotate via the rotating shaft 9. The drive roller 10 drives the outer ring of the bearing 13 under test to rotate. Then, the fiber optic counting sensor 12 counts the balls and analyzes the number of rotations of the bearing to determine the flexibility of the bearing 13. After the test is completed, the drive roller 10 stops rotating and returns to its original position. The lifting shaft 3 also returns to its original position and exits from the inner ring of the bearing. The tested bearing can then be transported to the next station via the conveyor line. This utility model has a simple and compact structure, accurate test results, controllable quality, reduced labor, and lower costs.
[0015] Preferably, the top of the support frame 6 is provided with a detection frame 14 horizontally, and a detection rod 15 is adjustablely mounted vertically at the end of the detection frame 14. The fiber optic counting sensor 12 is adjustablely mounted at the end of the detection rod 15.
