[0019] In this embodiment, the strip plate 26 is first moved horizontally by the telescopic cylinder 24, causing the strip plate 26 to slide along the limiting rod 27 inside the mounting base 23. This allows the strip plate 26 to smoothly move the chuck 25 horizontally. When the chuck 25 is in contact with the bearing, the bearing is clamped and fixed between the bearing rollers 18 by the two chucks 25, reducing displacement during subsequent grinding. Then, several lifting cylinders 5 are simultaneously activated to drive the top frame 6 downward.

The first motor 11 drives the toothed belt drive mechanism 12 to rotate, causing the grinding roller 17 to rotate, so that the grinding roller 17 polishes the outer wall of the bearing. Finally, the chuck 25 is moved away from the bearing, so that the chuck 25 no longer... The bearing is clamped and fixed. The second motor 16 is started to drive the drive wheel 19 to rotate. The drive wheel 19 drives the two driven wheels 20 to rotate via the transmission belt 21. This causes the driven wheels 20 to drive the two bearing rollers 18 to rotate synchronously via the rotating shaft 22. The bearing rollers 18 can then assist in the bearing flipping operation. After the bearing is flipped, the chuck 25 clamps and fixes the bearing to facilitate subsequent comprehensive grinding of the bearing's outer wall. Meanwhile, the exhaust fan 30 is started to draw the air inside the purification tank 29 into the external environment through the exhaust hood 34 and the exhaust port 33.

The dust collection hood 31 draws the debris that falls during the bearing grinding process into the purification tank 29 along with the air through the dust collection port 101. The activated carbon filter 36 filters the debris-containing gas. The filtered air is then drawn out by the exhaust fan 30 to collect and purify the debris-containing gas generated during the bearing grinding process, thus completing the use of the polishing and grinding equipment.
