[0046] The scraper 23 is attached to the right side of the first fixing ring 91 , and a baffle is provided in the middle of the scraper 23 . An oil leakage hole is opened on the scraper 23 .

[0047] A V-shaped leak hole is provided in the middle of the flat sweeping plate 25 , and one upper portion of the flat sweeping plate 25 is high and the other is low.

[0048] Take a sample of a newly produced bearing body 27 or a bearing body 27 that has been used for a period of time without any obvious problems, manually open the second fixing frame 14 so that the bearing body 27 has enough space to move, and then manually place the bearing body 27 on the first fixing ring 91, and control the four electric telescopic parts 93 to run simultaneously. The four electric telescopic parts 93 each drive a fixing rod 94 to move inward, and the four fixing rods 94 clamp the outer ring of the bearing body 27, effectively solving the problem of shaking and dislocation of the bearing body 27 on the left side of the first fixing ring 91.

[0049] After the bearing body 27 is installed, the second fixing frame 14 is released. Because the connecting rod 12 and the second fixing frame 14 are fixedly connected, under the action of the two torsion springs 13, the second fixing frame 14 drives the two pressure rods 15 to be stuck on the outside of the sealing ring of the bearing body 27. Because the two pressure rods 15 cannot return to their initial positions, the two pressure rods 15 have a strong effect on the sealing ring, controlling the electric slider 11 to move on the electric slide rail 10. The electric slider 11 drives the related parts thereon to move, and the two pressure rods 15 that follow the movement perform a circular motion on the outer surface of the sealing ring, thus forming an annular movable extrusion on the sealing ring. When the corresponding end of the sealing ring is lifted up, it means that there is a problem with the sealing performance of the sealing ring and a good sealing effect cannot be achieved.

[0050] Then the electric moving block 3 is controlled to move on the guide rail 2, and the electric moving block 3 drives the related parts on it to move together, and the transmission rod 71 that follows the movement is docked with the connecting seat 6, and the connecting seat 6 maintains the stability of the rotation of the transmission rod 71. At this time, the four struts 75 are located in the middle of the inner ring of the bearing body 27, and the two lap rings 72 are pushed respectively by the external mechanical arm; the two lap rings 72 move toward each other, and since the length of the connecting rod 73 is fixed, the four struts 75 move toward the direction of the inner ring of the bearing body 27 under the push of the connecting rod 73, and each elastic member 74 is responsible for the stability of one strut 75. When the four struts 75 are completely stuck in the inner ring of the bearing body 27, the operator inserts the fixing bolts into the slots of the transmission rod 71 to lap The ring 72 is fixed, and then the external robotic arm is separated from the contact with the overlapping ring 72, and then the power motor 5 is controlled to run. The output shaft of the power motor 5 drives the transmission rod 71 to rotate. Since the four support rods 75 are stuck in the inner ring of the bearing body 27, the bearing body 27 realizes the relative rotation of the inner and outer rings. At this time, the temperature sensor 17 inside the sealing box 16 detects the temperature of the outer surface of the bearing body 27, and records the value and time of its temperature increase. At the same time, the staff judges the sound of the bearing body 27 running. When the sound is loud and the temperature rises abnormally, it means that the bearing body 27 lacks grease inside. After the power motor 5 has been running for a period of time, the power motor 5 is reset to the initial position, and then the bearing body 27 is removed and replaced. During the detection process, check whether there is a large amount of grease inside the first fixing ring 91. When the amount of grease inside the first fixing ring 91 is obvious, it means that there is a grease fault in the bearing body 27 and the oil is thrown away. In order not to affect the next fault diagnosis, the servo motor 21 on the third support plate 20 is controlled to run, and the output shaft of the servo motor 21 drives the flat gear 22 to rotate, the flat gear 22 drives the gear ring 19, the gear ring 19 drives the second fixing ring 18 to rotate, and the second fixing ring 18 drives the scraper 23 to rotate. The scraper 23 cleans the right side of the first fixing ring 91 and scrapes off the grease attached to the inner wall. Finally, the scraper 23 stops at the position above the collection pipe 26, and then controls the electric cleaning plate 242 to run. The electric cleaning plate 242 It rotates on the fourth support plate 241, thereby pushing the oil stains remaining on the scraper 23 through the electric cleaning plate 242, thereby increasing the discharge speed of the oil stains; during the rotation of the second fixed ring 18, the sweeping plate 25 adheres to the outer surface of the second fixed ring 18 and scrapes off the attached grease, and at the same time the grease gathers inside the sweeping plate 25, and then the grease drips from the sweeping plate 25, and finally the grease is collected in the collection tube 26; the design of the scraper 23 on the second fixed ring 18 can not only realize the scraping of the grease inside the first fixed ring 91, but also the second fixed ring 18 and the first fixed ring 91 form a temporary space, so that the grease thrown out by the bearing body 27 during operation will not contaminate the transmission rod 71, thereby playing a protective role.

[0051] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
