[0029] Such as Figures 1 - 5As shown in the figure, during installation, place the cage above the four groups of rubber load-bearing wheels 201, then start the air pump 305 to input air through the positioning frame 3 into each group of support pistons 301, expand each group of support roller frames 302, fix the cage using the positioning support rollers 303, and lower the cage so that the bottom of the cage presses tightly against the rubber load-bearing wheels 201; after the detection is completed, reverse the air pump 305 to reset the support pistons 301 and then the cage can be removed; Start the carry motor 602 to drive the control lead screw 601 to rotate. The control lead screw 601 drives the nut seat 701 to move forward, and pushes the gauge 704 forward into the frame hole of the cage to detect whether the cage can accommodate the ball bearings; When the gauge 704 penetrates into the frame hole, the program automatically starts the drive motor 503 to drive the bevel gear disk 502 and the rotating sleeve 501 to rotate. When the rotating sleeve 501 rotates, it can drive the octagonal shaft 7 to rotate, and then the gauge 704 rotates within the frame hole to detect the frame hole of the revolving cage; Both the drive motor 503 and the carry motor 602 use servo motors and have feedback functions. If the movement of the drive motor 503 and the carry motor 602 is blocked due to the size problem of the cage, a fault prompt can be issued and the gauge 704 can be reset; The frame hole of the roller bearing is a rectangular frame, and a rectangular gauge 704 can be used for detection. The verification is achieved by testing whether the gauge 704 can pass through the cage normally.

[0030] Embodiment 2: On the basis of Embodiment 1, when the gauge 704 is normally reset after detecting one frame hole, first pull out the gauge 704 from the frame hole, and then the inclined surface of the trigger block 702 contacts the fitting roller 803 outside the trapezoidal trigger seat 802, pushing the trapezoidal trigger seat 802 and compressing the trigger piston 801. The hydraulic oil in the trigger piston 801 is input into the hydraulic piston 105 to expand the hydraulic piston 105 and push the control rack 106 forward. The control rack 106 drives the internal ratchet gear 103 to rotate, and then the transmission gear 102, the driven gear disk 108, and the linkage shaft 107 rotate synchronously. The linkage shaft 107 cooperates with the bevel gear to drive the rubber load-bearing wheel 201 to rotate, and the cage is rotated through friction to feed the frame hole to the next station.

[0031] Embodiment 3: On the basis of Embodiment 1, as Figures 6 - 9 shown in the figure, when detecting the periphery of the cage, start the electric cylinder 401 to push the connecting bar 402 forward, attach the edge measuring pulley 406 to the outside of the cage and apply stress. Then, the edge measuring pulley 406 will automatically attach during the rotation of the cage. If there are changes in the outside of the cage, it will push the edge measuring pulley 406 to move backward, and then the detection wheel frame 405 drives the distance measuring resistor 407 to move backward. By monitoring the resistance value change of the distance measuring resistor 407, the thickness of the cage can be monitored; When manufacturing the cage, holes need to be drilled from the outside, and then deburring operations are performed inside the cage. During this period, the cage may deform outward, so it is necessary to detect the outside of the cage.

[0032] Specific usage method and function of this embodiment: In the present invention, when in use, place the cage above the four groups of rubber bearing wheels 201, and then start the air pump 305 to input air through the positioning frame 3 into each support piston 301 to expand each support roller frame 302, and use the positioning support roller 303 to fix the cage and lower the cage so that the bottom of the cage presses against the rubber bearing wheels 201; Start the carry motor 602 to drive the control lead screw 601 to rotate. The control lead screw 601 drives the nut seat 701 to move forward, and pushes the gauge 704 forward into the frame hole of the cage to detect whether the cage can accommodate the ball bearings; when the gauge 704 penetrates into the frame hole, the program automatically starts the drive motor 503 to drive the bevel gear disk 502 and the rotating sleeve 501 to rotate. The rotating sleeve 501 drives the octagonal shaft 7 to rotate, and further rotates the gauge 704 in the frame hole to detect the frame hole of the cage in a turnover manner; If an obstacle occurs during this period, directly reset and emit a red light through the indicator light above the controller 101 to indicate unqualified, and use a green light to indicate qualified parts; When the detection of one frame hole is completed and the gauge 704 is normally reset, first withdraw the gauge 704 from the frame hole, and then the inclined surface of the trigger block 702 contacts the fitting roller 803 outside the trapezoidal trigger seat 802, pushing the trapezoidal trigger seat 802 and compressing the trigger piston 801. The hydraulic oil in the trigger piston 801 is input into the hydraulic piston 105 to expand the hydraulic piston 105 and push the control rack 106 forward. The control rack 106 drives the internal ratchet gear 103 to rotate, the internal ratchet gear 103 drives the transmission gear 102 to rotate, the transmission gear 102 drives the driven gear disk 108 to rotate, the driven gear disk 108 drives the linkage shaft 107 to rotate, and the linkage shaft 107 cooperates with the bevel gear to drive the rubber bearing wheel 201 to rotate, and rotates the cage through friction to feed the frame hole to the next station; When detecting again, the trigger block 702 moves forward and disengages from the fitting roller 803, and the trigger piston 801 can automatically extend through the spring. At this time, the control rack 106 moves backward, and the internal ratchet gear 103 idles, and the cage does not rotate; Start the electric cylinder 401 to push the connecting bar 402 forward, attach the edge measuring pulley 406 to the outside of the cage and apply stress, and then stop. As Figure 6 In the state shown, the edge measuring pulley 406 will automatically attach during the rotation of the cage. If the outside of the cage bulges, it will push the edge measuring pulley 406 to move backward, and then the detection wheel frame 405 drives the distance measuring resistor 407 to move backward. By monitoring the resistance value change of the distance measuring resistor 407, the thickness of the cage can be monitored; After completing the inspection of the cage for one revolution, reverse the air pump 305 to reset the support piston 301, and then the cage can be removed.
