[0018] Example 1: Please refer to Figures 1-4 , a sliding bearing polishing and grinding device, including a bottom plate 2, a top plate 14 is installed at the top end of the bottom plate 2, and a mounting block 8 is installed at the middle position of the bottom end of the top plate 14. Second electric telescopic rods 7 are installed on both sides of the mounting block 8, and one end of each second electric telescopic rod 7 is installed with a movable block 10 through bolts. The bottom end of the movable block 10 is connected to a connecting plate 6 by welding, and first electric telescopic rods 5 are installed around the bottom end of the connecting plate 6. The bottom end of the first electric telescopic rod 5 is connected to a mounting plate 12 through bolts, and a driving motor 4 is installed at the bottom end of the mounting plate 12. The output end of the driving motor 4 is connected to a mounting rod 13, and a polishing and grinding wheel 3 is connected to the bottom end of the mounting rod 13 by welding. A plug rod 9 is installed at the bottom end of the mounting block 8, and a pressing rod 16 is hinged to the periphery of the bottom end of the outer side of the plug rod 9 through a hinge. A threaded rod 15 is installed at the top end of the plug rod 9 through a bearing, and the bottom end of the threaded rod 15 penetrates through the bottom end of the inner part of the plug rod 9 and is connected to a rotating handle 1. A threaded block 17 is sleeved on the outer side of the threaded rod 15, and connecting rods 11 are hinged to the periphery of the outer side of the threaded block 17 through hinges;

[0019] One end of the connecting rod 11 penetrates through one end of the inner part of the plug rod 9 and extends to the outside of the plug rod 9, and one end of the connecting rod 11 is hinged to one end of the pressing rod 16 through a hinge;

[0020] Both the connecting rod 11 and the pressing rod 16 are in an inclined state, and both the connecting rod 11 and the pressing rod 16 are located in the same vertical plane;

[0021] The polishing and grinding wheels 3 are arranged on both sides of the plug rod 9, and the two polishing and grinding wheels 3 are axisymmetric about the vertical center axis of the plug rod 9;

[0022] The threaded block 17 is square in shape, and the outer side of the threaded block 17 is in contact with the inner wall of the plug rod 9;

[0023] The top end of the movable block 10 is in contact with the bottom end of the top plate 14, and the movable block 10 is slidably connected to the top plate 14;

[0024] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, during the use of this device, first take out the annular sliding bearing parts that need to be polished, pass them through the outside of the insertion rod 9, and then the user can drive the threaded rod 15 to rotate by manually rotating the rotating handle 1 due to the existence of the rotating handle 1. Due to the rotation of the threaded rod 15 and the restriction inside the insertion rod 9, under the threaded connection between the threaded rod 15 and the threaded block 17, the threaded block 17 can be driven to move vertically up and down during the rotation of the threaded rod 15. By utilizing the up and down movement of the threaded block 17, one end of the connecting rod 11 can be driven to move up and down. Since the connecting rod 11 is hinged to the abutting rod 16 through a hinge, and one end of the abutting rod 16 is hinged to the outside of the insertion rod 9, the connecting rod 11 can push and pull the abutting rod 16, so that the angle between the connecting rod 11 and the abutting rod 16 can be adjusted flexibly. Thus, the four abutting rods 16 can be deflected, resulting in the four abutting rods 16 performing opening and contracting actions. In this way, the four abutting rods 16 can abut against the inner wall of the annular sliding bearing parts, providing a stable fixing effect on the annular sliding bearing parts and keeping them stable in space, facilitating the subsequent polishing process. Then, due to the existence of the driving motor 4 in this device, by turning on the driving motor 4, the mounting rod 13 and the polishing wheel 3 can be driven to rotate under the drive of the driving motor 4. By utilizing the rotation of the mounting rod 13 in contact with the surface of the annular sliding bearing parts, polishing treatment can be carried out. And due to the existence of the first electric telescopic rod 5 and the second electric telescopic rod 7, under the telescopic control of the first electric telescopic rod 5 and the second electric telescopic rod 7, the polishing wheel 3 can be moved horizontally and vertically, ensuring that the polishing wheel 3 can stably contact the surface of the annular sliding bearing parts. And this device is provided with two polishing wheels 3, which are respectively arranged on both sides of the insertion rod 9. When polishing with the polishing wheels 3, the rotation directions of the two polishing wheels 3 can be adjusted to be opposite, so that during the polishing process of the two polishing wheels 3, the annular sliding bearing parts have good stability, avoiding the rotation phenomenon of the annular sliding bearing parts caused by the rotation of the polishing wheels 3 and increasing the stability of this device.
