[0002] Pipes are essential materials for construction projects. Commonly used ones include water pipes, drainage pipes, gas pipes, heating pipes, electrical conduits and rainwater pipes. They are generally made of steel, but there are also pipes made of copper, aluminum and plastic. After common steel pipes are produced, in order to meet the requirements of use, the burrs on the inner and outer walls of the steel pipes need to be removed and the pipes need to be polished to a certain degree of smoothness.

[0003] Existing synchronous grinding devices for inner and outer walls of pipes, such as the authorized Chinese utility model patent with publication number CN216327419U entitled a rust removal and grinding device, use inner and outer brushes to synchronously grind the inner and outer walls of pipes, but the grinding area depends on the length of the inner and outer brushes. The length of the inner and outer brushes is fixed, and it is impossible to synchronously grind the inner and outer walls of longer pipes, and the overall applicability is low. Therefore, it is necessary to design a synchronous grinding device for inner and outer walls of pipes to address the above problems. Utility Model Content

The above-mentioned structural design enables the adjusting threaded rod 7 to push the outer grinding plate 8 to move vertically stably when rotating at the top of the mounting frame 6, so that the bottom surface of the outer grinding plate 8 can fit the outer wall of the pipe with different diameters.

[0034] In one of the preferred embodiments, the horizontal threaded rod 10 is threadedly connected to the movable plate 11, and the horizontal threaded rod 10 is horizontally symmetrically distributed about the center of the movable plate 11. The above-mentioned structural design enables the horizontal threaded rod 10 to stably drive the movable plate 11 to move horizontally when rotating.

[0036] In one of the preferred embodiments, the clamping plate 18 is horizontally arranged symmetrically about the center of the positioning plate 14, and the clamping plate 18 is arranged as an arc-shaped plate structure. The above-mentioned structural design enables the clamping plate 18 to fit tightly with the inner and outer walls of pipes of different diameters, thereby ensuring the fixing effect of pipes of different diameters.

[0037] The working principle of the utility model is: when using the device, first Figure 2 The locking nut 17 installed at the end of the locking bolt 16 near the center of the positioning plate 14 on the middle positioning plate 14 is rotated away from the side of the positioning plate 14, and the clamping plate 18 near the center of the positioning plate 14 is moved down, so that the distance between the clamping plates 18 connected to the same limit window 15 is increased, and then a forklift or lifting equipment is used to keep the pipe to be polished horizontally and lift or hoist it so that one end of the pipe is aligned with the Figure 2 Align the center of the middle positioning disk 14, move the pipe horizontally until one end of the pipe fits against the side of the positioning disk 14, move the clamping plate 18 near the center of the positioning disk 14 with the locking bolt 16 to slide along the limiting window 15 toward the inner wall of the pipe, until the outer side of the clamping plate 18 near the center of the positioning disk 14 fits tightly against the inner wall of the pipe, rotate the locking nut 17 at the end of the locking bolt 16 connected to the clamping plate 18 to reset and squeeze the positioning disk 14, fix the clamping plate 18, and rotate the locking nut 17 at the end of the locking bolt 16 connected to the clamping plate 18 away from the center of the positioning disk 14 away from the positioning disk 14, push the clamping plate 18 away from the center of the positioning disk 14 to fit tightly against the outer wall of the pipe, and then rotate the locking nut 17 to reset and squeeze the positioning disk 14 to fix one end of the pipe;

[0038] Then control the servo motor 9 to drive the horizontal threaded rod 10 to rotate in the positive direction, and the horizontal threaded rod 10 rotates and drives Figure 1 The movable plate 11 and the positioning plate 14 in the middle move horizontally to the left, until the positioning plate 14 pushes the pipe to the left until the left end of the pipe is located below the outer grinding plate 8 and between the inner grinding plate 5. During this process, the forklift or lifting equipment always keeps the pipe horizontal, and then controls Figure 3 All electric telescopic rods 4 are extended until the surface of the inner grinding plate 5 is closely fitted with the inner side of the left end of the pipe, the forklift or lifting equipment is removed, and the servo motor 9 is controlled to stop working and rotate in the same direction at the same time. Figure 2 The adjusting threaded rod 7 is symmetrically distributed in the middle, and the adjusting threaded rod 7 is stably rotated downward on the top of the mounting frame 6 and pushes the outer grinding plate 8 downward until the bottom curved surface of the outer grinding plate 8 fits with the top of the outer wall of the pipe, and the adjusting threaded rod 7 is stopped from rotating, and the position of the outer grinding plate 8 is fixed by the thread self-locking;

[0039] Finally, the side motor 12 is controlled to start working. The side motor 12 drives the horizontal shaft 13 to rotate stably with the positioning disk 14 and the fixed pipe. The inner and outer walls of the left end of the pipe rotate relative to the inner and outer grinding plates 5 and the outer grinding plates 8. The inner and outer grinding plates 5 and the outer grinding plates 8 perform synchronous rotation and grinding on the inner and outer walls of the left end of the pipe. At the same time, the servo motor 9 is controlled to continue working, driving the horizontal threaded rod 10 to rotate and drive the movable plate 11 to move stably to the left, so that the inner and outer grinding plates 5 and the outer grinding plates 8 perform continuous synchronous grinding on the inner and outer walls of the pipe. After grinding, the servo motor 9 is controlled to drive the horizontal threaded rod 10 to rotate in the opposite direction, so that the pipe moves right and resets, and the electric telescopic rod 4 is controlled to shorten, and the upward adjustment threaded rod 7 is used to separate the inner and outer grinding plates 5 and the outer grinding plates 8 from the pipe, and all the locking nuts 17 are rotated away from the side of the positioning disk 14 to release the lock on the clamping plate 18. The clamping plate 18 no longer fixes the right end of the pipe, and the polished pipe can be removed.
