[0034] Please refer to Figure 4-6, the vibration structure 5 includes an inner shaft 53 rotatably arranged on the outer surface of the base 1. A driven gear 52 and a transmission gear 54 are respectively fixedly connected to the outer surface of the inner shaft 53. An outer shaft 55 is rotatably arranged on the outer surface of the inner shaft 53. A linkage gear 56 is fixedly connected to the outer surface of the outer shaft 55. A raised block 514 is fixedly connected to the outer surface of the outer shaft 55. A shock absorption assembly 57 is arranged between the support block 3 and the base 1. The shock absorption assembly 57 includes a rotating block 571 rotatably arranged on the outer surface of the base 1. A chute 572 is opened on the lower outer surface of the support block 3. A sliding block 573 is movably arranged inside the chute 572. A shock absorber 574 is arranged between the sliding block 573 and the rotating block 571.

[0036] Please refer to Figure 8-10, the extrusion structure 8 includes a sliding groove 81 formed on the outer surface of the base 1. A sliding bracket 82 is slidably arranged in the groove of the sliding groove 81 corresponding to the outer surface of the base 1. A rack 83 is fixedly connected to the outer surface of the sliding bracket 82. A cylinder B84 is fixedly arranged on the outer surface of the base 1. The output end of the cylinder B84 is fixedly connected to a transmission column 85. One end of the transmission column 85 is engaged with the rack 83 through a transmission gear 86. The transmission column 85 penetrates through the base 1, and the transmission column 85 is movably connected to the base 1. The other end of the transmission column 85 is engaged with the first bevel gear 71 through a fourth bevel gear 87. A fixed bracket 88 is fixedly connected to the outer surface of the sliding bracket 82. A connecting spring 89 is connected to the lower end of the fixed bracket 88. The lower end of the connecting spring 89 is connected to a movable bracket 810. A limiting groove 811 is formed inside the support block 3. A fixing plate 812 is fixedly connected to the outer surface of the movable bracket 810. A return spring 813 is arranged inside the limiting groove 811. The engagement between the fourth bevel gear 87 and the first bevel gear 71 is realized by the telescopic movement of the cylinder B84. Both ends of the connecting spring 89 are fixedly connected to the fixed bracket 88 and the movable bracket 810 respectively. The movable bracket 810 penetrates through the support block 3, and the movable bracket 810 is slidably connected to the support block 3. The pressing block 4 can apply a downward pressure to the bearing, so that the real pressure during the use of the bearing can be simulated during the detection process. At the same time, the possible detachment of the bearing can be prevented through the action of the limiting groove 811, the fixing plate 812 and the return spring 813. The engagement and separation between the fourth bevel gear 87 and the first bevel gear 71 can be realized by the telescopic movement of the cylinder B84, which can make the detection effect better;

[0037] It should be noted that protective gearboxes are provided outside all gears in the present invention, and the gears are just in an engaged state during the moving and lapping process.

[0038] The working principle of the present invention: When in use, the user can first put the inner cavity of the bearing on the corresponding connection block 15. The driving gear 51 is driven to slide by the slider 13 so that the driving gear 51 is engaged with the driven gear 52. The driving gear 51 is driven to rotate by the motor 11, so that the driven gear 52 drives the inner shaft 53 and the transmission gear 54 to rotate together. At the same time, the cylinder A510 starts to extend, so that the clamping block 512 is inserted into the position corresponding to the clamping groove 59. The rotating rod 58 is driven to rotate the rotating disc 9 through the engagement between the transmission gear 54 and the fifth gear 513, so that the clamping member 10 completes the clamping of the bearing. Then, the cylinder A510 contracts, so that the clamping block 512 disengages from the clamping groove 59.

[0039] After the bearing is clamped, the slider 13 drives the motor 11 to slide, so that the driving gear 51 meshes with the linkage gear 56, causing the outer shaft 55 to rotate. The raised block 514 continuously pats the support block 3, causing the support block 3 to vibrate, and then the bearing can vibrate together, simulating the vibration when the bearing is in use.

[0040] It should be noted that while the support block 3 vibrates, the rotation of the second bevel gear 72 causes the first bevel gear 71 to drive the fourth bevel gear 87 to rotate. The fourth bevel gear 87 drives the transmission gear 86 to rotate, so that the rack 83 drives the sliding bracket 82 to move downward. The sliding bracket 82 drives the fixed bracket 88 to move downward, causing the connecting spring 89 to squeeze the movable bracket 810 downward, so that the extrusion block 4 applies pressure to the bearing downward. After applying the appropriate pressure, the cylinder B84 contracts to separate the fourth bevel gear 87 from the first bevel gear 71, avoiding continuous rotation of the transmission column 85 to increase the pressure. At the same time, the fixing plate 812 squeezes the reset spring 813 downward to contract, so that the lower end of the movable bracket 810 limits the position of the bearing. At the same time, when not squeezing downward, the movable bracket 810 rebounds to its original position under the action of the reset spring 813.

[0041] During the rotation of the driving gear 51, the pushing block 61 squeezes the roller 63, causing the roller 63 to roll on the outer surfaces of the driving gear 51 and the pushing block 61. When the pushing block 61 rotates to the position of the roller 63 and relative rolling occurs, the support block 3 will swing back and forth in the horizontal direction, simulating the steering when the bearing is in use.

[0042] It should be noted that during the vibration and steering of the bearing, the sliding of the slider 573 in the chute 572 can guide the steering. At the same time, the shock absorber 574 can damp the support block 3, simulating the shock absorption when the bearing is in use. The connecting spring 89 can meet the change in the rotation amplitude of the upper end of the support block 3.

[0043] When the main shaft 2 drives the universal joint 14 to rotate, it can meet the steering when the support block 3 vibrates and sways. The universal joint 14 drives the connecting block 15 to rotate, causing the bearing to rotate, and the rotation of the bearing is detected. After a group of bearings are detected, the bearing can be released by the clamping member 10 by reversing the rotating rod 58, the bearing is taken out, and then the next group of bearings can be detected.

[0044] It should be noted that when applying pressure to the bearing through the pressing structure 8, as the pressure increases, the vibration generated under the action of the vibration structure 5 becomes greater. Through the action of the air cylinder B84, the sliding bracket 82 can be moved downward to different positions to maintain different magnitudes of pressure. In the case of greater pressure, the vibration of the support block 3 is greater, so that the bearing can be detected under different magnitudes of pressure, and the quality of the bearing can be detected under different pressures and different vibration amplitudes.

[0045] In summary, the present invention can simulate the vibration, steering of the bearing during use, the pressure received by the bearing during use, and the shock absorption during use, so as to more accurately detect the quality of the bearing.
