Both the first motor and the second motor are mounted on a movable worktable. The movable worktable has multiple fixed circular holes, and support bearings are installed in the fixed circular holes. Friction rollers are installed inside the fixed circular holes and pass through the fixed circular holes to connect with the output end of the second motor. The movable worktable is mounted on a horizontal plate, and a slide rail is provided on the horizontal plate. The horizontal plate and the slide rail are connected in cooperation. A fixed plate is installed below the horizontal plate and is connected to an inner support frame. A lifting slide rail is installed inside the inner support frame and is connected to the fixed plate. A lifting motor is installed on the outside of the inner support frame.

[0005] Preferred configuration: A fixed crossbeam is installed on the outer support frame, multiple pipe support frames are installed on the fixed crossbeam, and telescopic rods are installed inside the pipe support frames.

[0006] Preferably, the pipe support frame, friction roller, and fixed circular hole are on the same horizontal line, and the lifting slide rail is internally connected to the lifting motor.

[0007] Preferably, the fixed crossbeam is fixedly connected to the outer support frame, and the horizontal plate is fixedly connected to the fixed plate.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] 1. Synchronous telescopic support arm: Multiple arms move synchronously through a single screw, ensuring the grinding head is centered;

[0010] 2. Dynamic pressure compensation: The grinding pressure is adjusted in real time according to the pipe wall deformation to avoid damaging thin-walled pipes;

[0011] 3. Grinding long pipes: Suitable for long pipes. The grinding roller can be extended or retracted according to the length of the pipe. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-3 As shown, a polishing and grinding device for the inner and outer walls of a pipe cylinder includes a first motor 2 and a second motor 3. Both the first motor 2 and the second motor 3 are mounted on a movable worktable 1. The movable worktable 1 has multiple fixed circular holes 12, and support bearings are installed on the fixed circular holes 12. Friction rollers 11 are installed inside the fixed circular holes 12. The friction rollers 11 pass through the fixed circular holes 12 and are connected to the output end of the second motor 3. The movable worktable 1 is mounted on a horizontal plate 4, and a slide rail is installed on the horizontal plate 4. The horizontal plate 4 is connected to the slide rail. A fixed plate 5 is installed below the horizontal plate 4 and is connected to an inner support frame 10. A lifting slide rail 8 is installed inside the inner support frame 10 and is connected to the fixed plate 5. A lifting motor 9 is installed on the outside of the inner support frame 10.

[0018] A fixed crossbeam 13 is provided on the outer support frame 6, and multiple pipe support frames 7 are provided on the fixed crossbeam 13. Telescopic rods are provided inside the pipe support frames 7. The pipe support frames 7, friction rollers 11, and fixed round holes 12 are on the same horizontal line. The lifting slide rail 8 is internally connected to the lifting motor 9.

[0019] During operation, the friction roller 11 is installed and connected to the output end of the first motor or the second motor through the fixed round hole 12. The support bearing in the fixed round hole 12 is used to fix the friction roller 11. The pipe is fixed on the pipe support frame 7. The friction roller 11 rotates to grind the inner wall of the pipe. Depending on the length of the pipe, the grinding work can be carried out by adjusting the movable worktable 1. The movable worktable 1 moves and is adjusted along the slide rail on the horizontal plate 4. The height of the movable worktable 1 can also be adjusted according to the diameter of the pipe. The horizontal plate 4 is pushed upward by the lifting motor 9 and the lifting slide rail 8 to raise the movable worktable 1.
