[0027] A driving gear 203 is fixedly connected to the surface of the driving rod 202. Planetary gears 204 are fixedly connected to the surfaces of the three linkage rods 201. The height of the planetary gears 204 corresponds to that of the driving gear 203.

The top ends of the linkage rods 201 extend to the outside of the base box 1, and a rotating chassis 205 is fixed to the top ends of the linkage rods 201. The rotating chassis 205 can support and limit the bottom of the bearing, and the driving gear 203 can drive the three planetary gears 204 to rotate in the same direction, thereby driving the three rotating chassis 205 to rotate simultaneously.

[0028] Three limiting through holes are formed on the surface of the limiting circular plate 3. Limiting bearings 13 are fixedly arranged on the inner walls of the limiting through holes. The linkage rods 201 are rotatably connected to the surface of the limiting circular plate 3 through the limiting bearings 13.

[0029] A limiting clamping rod 206 is fixedly connected to the upper surface of the rotating chassis 205. Four rubber anti-slip sheets 211 are fixedly arranged on the surface of the limiting clamping rod 206. The four rubber anti-slip sheets 211 are evenly distributed on the surface of the limiting clamping rod 206. The limiting clamping rod 206 is used for internally clamping and limiting the inner ring of the bearing.

[0030] Through the above technical solution, the rubber anti-slip sheets 211 can be used to improve the clamping stability of the limiting clamping rod 206 on the bearing.

[0031] A fixing frame 4 is fixedly connected to the upper surface of the bottom plate. An electric telescopic rod 5 is fixedly installed on the upper surface of the fixing frame 4. A rotating motor 6 is fixedly arranged at the telescopic end of the electric telescopic rod 5. The output shaft of the rotating motor 6 is fixedly connected to a movable frame 7.

[0032] A strip-shaped guide shell 8 is fixedly connected to the lower surface of the movable frame 7. A bidirectional lead screw 9 is rotatably connected to the inner wall of the strip-shaped guide shell 8. The left and right ends of the bidirectional lead screw 9 both extend to the outside of the strip-shaped guide shell 8, and adjusting knobs 11 are fixedly connected to both ends of the bidirectional lead screw 9. Two positioning and mounting plates 10 are threadedly connected to the surface of the bidirectional lead screw 9. Bolt fixing holes are formed on the surfaces of the positioning and mounting plates 10.

[0033] Through the above technical solution, grinding parts or oil painting brushes can be installed and fixed on the positioning and mounting plates 10 by using the bolt fixing holes, and the distance between the two positioning and mounting plates 10 can be conveniently adjusted according to the size of the bearing, which is suitable for surface treatment of bearings of different sizes.

[0034] It should be noted that by arranging an electric telescopic rod 5, a rotating motor 6 and a movable frame 7 on the surface of the fixing frame 4 directly above the base box 1, after positioning the bearing, the rotating motor 6 can be used to drive the movable frame 7 to rotate, and then the bidirectional lead screw 9 can be driven to rotate by rotating the adjusting knob 11. Furthermore, the distance between the two positioning and mounting plates 10 can be adjusted by the bidirectional lead screw 9, and a grinding piece or an oil brush can be installed on the surface of the positioning and mounting plate 10. Then, the rotating motor 6 is used to drive the positioning and mounting plate 10 to rotate around the bearing, thereby facilitating processing operations such as grinding or oiling the surface of the bearing.

[0035] A rectangular limiting hole 12 is formed in the lower surface of the strip-shaped guide shell 8, and the front and rear surfaces of the positioning and mounting plate 10 are both slidably connected to the inner wall of the rectangular limiting hole 12.

A worm 209 is fixedly connected to the surface of the transmission rod 208. A worm gear 210 is fixedly installed on the surface of the driving rod 202. The position of the worm gear 210 corresponds to that of the worm 209, and the worm 209 meshes with the worm gear 210.

[0037] Working principle: When performing processing operations on the surface of the bearing, first, the bearing is sleeved on the surfaces of the three limiting and clamping rods 206. Then, the driving motor 207 is used to drive the worm 209 on the surface of the transmission rod 208 to rotate, thereby driving the worm gear 210 and the driving rod 202 to rotate. Next, the driving gears 203 on the surface of the driving rod 202 are used to drive the three planetary gears 204 to rotate simultaneously, thereby driving the three linkage rods 201 and the rotating chassis 205 at their tops to rotate simultaneously. Moreover, the rotating chassis 205 can drive the limiting and clamping rods 206 to rotate, causing the three limiting and clamping rods 206 to generate equidistant displacements. Thus, the three limiting and clamping rods 206 are used to tightly press against and limit the inside of the bearing, which is suitable for positioning bearings with different inner diameters. Since the contact area between the limiting and clamping rods 206 and the surface of the bearing is small, it is convenient for the staff to perform surface treatment on the bearing.
