[0024] By cooperating with the movable groove 20 and the compression spring 22, the distance between the two clamping plates 6 can be adjusted by adjusting the position of the moving block 21 inside the movable groove 20 during use, thereby enabling the device to clamp and apply oil to bearings 7 of different sizes.
[0025] The center of the surface of the processing table 1 is provided with an oil drain port 2, the bottom of the oil drain port 2 is provided with a filter screen 19, and the bottom of the oil drain port 2 is movably installed with an oil return pipe 11.
[0026] A hydraulic lifting cylinder 8 is fixedly installed at the rear of the top of the processing table 1. A lifting plate 9 is fixedly connected to the output end of the hydraulic lifting cylinder 8. A metering pump 13 is fixedly installed at the front of the top of the lifting plate 9. An oil storage tank 10 is fixedly installed at the center of the top of the lifting plate 9. The end of the oil return pipe 11 is connected to the inside of the oil storage tank 10. An oil injection pipe 12 is provided at the top of the oil storage tank 10.
[0027] By using the oil return pipe 11 and the filter screen 19, when the bearing 7 is being lubricated, excess oil will enter the position of the filter screen 19 through the oil drain port 2, be filtered by the filter screen 19, and then flow back to the inside of the oil storage tank 10 through the oil return pipe 11, thus avoiding the situation of over-applying and wasting lubricating oil.
[0028] The fixed displacement pump 13 has an oil inlet 14 on one side, which is connected to the inside of the oil storage tank 10 through a pipe. A servo motor 16 is fixedly installed at the bottom front of the lifting plate 9. The output end of the servo motor 16 is connected to a rotating shaft 17 through a coupling.

Each oiling head 28 has an oil spray nozzle 29 on its surface.
[0031] With the cooperation of the ring frame 27 and the oiling head 28, when applying oil to the bearing 7, the ring frame 27, which is adapted to the size of the bearing 7, is first installed inside the mounting groove 23 by threads. Then, the T-shaped plate 4 is moved to the position of the oil drain 2 by the conveying track groove 3 and the conveying roller shaft 5. At this time, the bearing 7 is located at the bottom of the connecting seat 18. The oil inside the oil storage tank 10 can be drawn out by the metering pump 13 and delivered to the inside of the oil delivery chamber 25 through the oil outlet pipe 15. Then, the lifting plate 9 is driven down by the hydraulic lifting cylinder 8, so that the ring frame 27 is inserted into the inside of the bearing 7 and the oiling head 28 is in contact with the balls inside each bearing 7. Then, the rotating shaft 17 is driven to rotate by the servo motor 16, so that the ring frame 27 swings and rotates inside the bearing 7. At this time, the lubricating oil will be sprayed onto the surface of the bearing 7 through the oil spray nozzle 29 and pushed by the oiling head 28 to move the balls, so that the lubricating oil can be evenly applied to the inside of the bearing 7 and avoid dead corners.

[0034] When applying oil to the bearing 7, excess oil will enter the filter screen 19 through the oil drain 2 and be filtered by the filter screen 19. Then, it will flow back to the inside of the oil reservoir 10 through the oil return pipe 11, thus avoiding the situation of applying too much oil and wasting lubricating oil.
[0035] When applying oil to the bearing 7, the annular frame 27, which is adapted to the size of the bearing 7, is first installed inside the mounting groove 23 by threads. Then, the T-shaped plate 4 is moved to the position of the oil drain 2 by the conveying track groove 3 and the conveying roller shaft 5. At this time, the bearing 7 is located at the bottom of the connecting seat 18. The oil inside the oil storage tank 10 can be drawn out by the metering pump 13 and delivered to the inside of the oil delivery chamber 25 through the oil outlet pipe 15. Then, the lifting plate 9 is driven down by the hydraulic lifting cylinder 8, so that the annular frame 27 is inserted into the inside of the bearing 7 and the oiling head 28 is in contact with the balls inside each bearing 7. Then, the rotating shaft 17 is driven to rotate by the servo motor 16, so that the annular frame 27 swings and rotates inside the bearing 7. At this time, the lubricating oil will be sprayed onto the surface of the bearing 7 through the oil spray nozzle 29 and pushed by the oiling head 28 to move the balls, so that the lubricating oil can be evenly applied inside the bearing 7 and avoid dead corners.
