[0033] When both sides of the cutter 36 are adjusted to the outside, and the rotating switch screw rod 311 drives the cutting slider 34 to move to the outermost side, then by adjusting the cutter adjusting screw rod 351, the cutter 36 is in the same position, then the switching motor 31 is started to drive the cutting seat 33 to move to one end of the switching cavity 321, then the switching screw rod 311 is rotated in the opposite direction, so that one side of the cutter 36 abuts against the outside of the workpiece, and then the switching screw rod 311 is continuously rotated to feed the cutter 36 inward to adjust the cutting amount of the outside of the workpiece. After a period of time, the switching motor 31 adjusts the cutting seat 33 to slide to the other side, at which time the other cutter abuts against the workpiece to replace the previous cutter for cutting.

[0034] In summary, the sliding bearing inner and outer wall cutting equipment can control the sliding of the cutting seat 33 as a whole by the switching motor 31, and only one cutter is used for cutting. After a period of time, the switching motor 31 adjusts the cutting seat 33 to slide to the other side, at which time the other cutter abuts against the bearing to replace the previous cutter for cutting, so as to automatically and frequently switch the cutting cutter, giving the cutter and the workpiece a certain cooling time, which can effectively avoid the surface of the workpiece from being overheated and causing surface burns and reducing surface hardness and wear resistance. The switching of the cutter can greatly reduce the wear and consumption of the cutter. By adjusting the position of the inner and outer adjusting blocks 35, the separate cutting and simultaneous cutting of the inner and outer sides of the bearing can be adapted. On the one hand, different cutter tables do not need to be switched to cut the inner and outer sides, and on the other hand, simultaneous cutting can greatly shorten the processing time of the sliding bearing and improve the efficiency.
