The drive shaft 2 and the driven roller 4 are made of rubber. The rotation of the drive shaft 2 and the driven roller 4 drives the rotation of the surface steel pipe, which, in conjunction with the rotation of the outer polishing head and the inner polishing head 10, effectively enhances the polishing effect of the steel pipe.

[0020] The base 1 has a limiting groove inside, and the base 1 slides with the outer side of the moving plate 5 through the limiting groove. The moving plate 5 is threaded to the outer side of the lead screw 7 through a threaded hole. The side of the base 1 is fixed to the moving motor 6 by bolts. The output end of the moving motor 6 is welded to the lead screw 7. The moving motor 6 drives the lead screw 7 to rotate, which drives the moving plate 5 to move horizontally, thus driving the internal grinding head 10 to move, thereby meeting the internal grinding and polishing needs of steel pipes of different lengths. The upper surface of the moving plate 5 is fixed to the polishing motor 8 by bolts. The output end of the polishing motor 8 is connected to the rotating... The rod 9 is welded and fixed, and one end of the rotating rod 9 is welded and fixed to the inner grinding head 10. The upper surface of the base 1 is welded and fixed to two symmetrical brackets 11. The brackets 11 are rotatably connected to the guide rollers 12 through shafts. The guide rollers 12 have arc-shaped grooves on their sides, and the guide rollers 12 fit against the outer side of the rotating rod 9 through the arc-shaped grooves. The guide rollers 12 can limit the rotation of the rotating rod 9 to prevent it from shaking during long-distance movement. At the same time, the arc-shaped grooves on the side of the guide rollers 12 can also be used to lock the outer side of the rotating rod 9 to prevent it from shaking during rotation, thus ensuring the stability of the grinding by the inner grinding head 10.

[0021] A guide roller 12 is provided on the upper surface of the base 1, and a fixing frame 13 is provided on the upper surface of the base 1. The fixing frame 13 is rotatably connected to one end of the lead screw 14. A movable plate 15 is provided on the outer side of the lead screw 14, and a grinding device 18 is provided at the bottom of the movable plate 15. Support rods 19 are provided on both sides of the grinding device 18.

[0022] The upper surface of the base 1 is welded and fixed to the bottom of the fixed frame 13. The inner wall of the fixed frame 13 is welded and fixed to the guide rod. The second lead screw 14 and the guide rod are located on both sides of the second movable plate 15. A motor is installed on the side of the fixed frame 13, and the output end of the motor is connected and fixed to the second lead screw 14. The second movable plate 15 is threaded to the outer thread of the second lead screw 14 through a threaded hole. The upper surface of the second movable plate 15 is connected and fixed to the telescopic rod 16 by bolts. The output end of the telescopic rod 16 extends to the bottom of the second movable plate 15 and is welded and fixed to the mounting plate 17. The mounting plate 17 is connected and fixed to the grinding equipment 18. The bottom surface of the mounting plate 17 is welded and fixed to the support rod 19. The support rod 19 is equipped with ball bearings 20, and the surface of the ball bearings 20 is smooth.

[0023] Working principle: In use, the stainless steel pipe is placed between the drive roller 3 and the driven roller 4. The motor drives the drive shaft 2 to rotate the drive roller 3, which in turn rotates the steel pipe. Subsequently, the telescopic rod 16 moves the mounting plate 17 and the grinding device 18 down to a suitable height. The mounting plate 17 simultaneously moves the support rod 19 down, fixing the steel pipe to the surface of the drive roller 3 and the driven roller 4, preventing the steel pipe from detaching from the surface of the drive roller 3. The grinding device 18 rotates the outer grinding head to grind the outer side of the steel pipe. The rotation of the lead screw 14 drives the moving plate 15 and the grinding device 18 to move horizontally. The movement of the inner grinding head 10 grinds the outer side of the steel pipe, effectively reducing grinding dead angles. The motor causes the lead screw 7 to rotate, driving the moving plate 5 to move inside the base 1 until the inner grinding head 10 is inserted into the steel pipe. The polishing motor 8 causes the rotating rod 9 to rotate the inner grinding head 10, which grinds and polishes the inner wall of the steel pipe. The movement of the rotating rod 9 is limited by the bracket 11 and the guide roller 12 to prevent the rotating rod 9 from shaking during long-distance movement. At the same time, the arc groove on the side of the guide roller 12 is used to lock the outer side of the rotating rod 9 to prevent the rotating rod 9 from shaking during rotation, ensuring the stability of the grinding by the inner grinding head 10.
