One end of the tooth plate 4 extends to the outside of the U-shaped plate 11 and is radially rotatably installed with a support rod 41. A motor 2 42 is fixedly installed on the support rod 41, and a support shaft 43 is axially fixedly connected to the output shaft of the motor 2 42.

[0035] Working principle: When in use, first turn on the power supply and insert the power pipe to be polished from the installation tube 2 on the right. With the cooperation of the guide wheel 22, the slider 221 and the spring 222 and other components, the power pipe can be supported and guided, and the clamping function can be realized. It can adapt to different power pipes. Then control the power pipe to move to the left, and start the motor 33 at the same time. The motor 33 controls the rotation of the toothed disc 31 through the driving gear 34, thereby driving the polishing brush 32 to polish the outside of the power pipe. The waste chips generated during the polishing process are intercepted by the conical tube 3 to prevent them from splashing everywhere, and after interception, they are discharged through the multiple slag holes set on the conical tube 3.

[0036] When it is necessary to grind the inner wall of the power pipe, the support rod 41 is adjusted to a vertical state and limited by the cooperation of the limit bolt and the screw hole, so that the support shaft 43 remains aligned with the axis of the mounting tube 2, and then the transmission gear 402 is controlled to rotate by the motor 3 401, so that the tooth plate 4 can be controlled to adjust the lateral position, and then the support shaft 43 can be controlled to drive multiple grinding modules to move laterally with the cooperation of the support rod 41. The setting of the torsion spring 451 can keep the grinding block in a stable contact state with the inner wall of the power pipe, so that the inner wall of the power pipe can be ground. The entire grinding process is efficient and stable, and can adapt to power pipes of different diameters, thereby improving the efficiency and flexibility of grinding.
