[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] Reference Figures 1 to 4 As an embodiment of the present invention, a high-precision pipe cutting device is provided. This high-precision pipe cutting device includes a pipe feeding mechanism 1 and an auxiliary mechanism 3. A pipe feeding mechanism 2 is provided on one side of the end point of the pipe feeding mechanism 1, and a straightening mechanism 4 is provided on one side of the auxiliary mechanism 3. A cutting box 5 is provided at the end point of the pipe feeding mechanism 2. The straightening mechanism 4 includes a frame block 41, a third cylinder 42, and a straightening plate 43. The third cylinder 42 is located on the top of the frame block 41, and the straightening plate 43 is located on the piston rod of the third cylinder 42.
[0024] Specifically, the upper tube mechanism 1 includes a fixed plate 11, a driving pulley 12, a driven pulley 13, a conveyor belt 14, a driving roller 15, and a driven roller 16. The fixed plate 11 is disposed between the driving roller 15 and the driven roller 16. The driving pulley 12 is disposed on the driving roller 15, and the driven pulley 13 is disposed on the driven roller 16. The conveyor belt 14 is connected to the driving pulley 12 and the driven pulley 13. It is worth noting that the movement from the driven roller 16 to the driving roller 15 is the upper tube direction. The driven roller 16 is the starting point of the upper tube, and the driving roller 15 is the ending point of the upper tube. A drive source is connected to the driving roller 15. Preferably, a motor 6 is directly connected to the driving roller 15. In some embodiments, the motor 6 drives the driving roller 15 to rotate through belt drive, chain drive, or gear drive.
[0025] Specifically, the auxiliary mechanism 3 includes a support plate 31, a support frame 32, a support roller 33, and a limiting post 34. The support plate 31 is located on one side of the fixed plate 11, and the support frame 32 is located on the top of the support plate 31. The support frame 32 has two lugs along the feeding direction. The support roller 33 is rotatably located between the two lugs on the support frame 32. The upper edge of the support roller 33 is not lower than the upper edge of the support frame 32. The limiting post 34 is rotatably located on the side near the end point of the upper pipe mechanism 1. Based on limiting the pipe material, the smoothness of the equipment conveying the pipe material is improved.
[0026] Specifically, the pipe feeding mechanism 2 includes a track 21, a large module 22, a first cylinder 23, a second cylinder 24, a side plate 25, a fixing block 26, a connecting plate 27, and a gripper 28. The track 21 is located on one side of the end point of the upper pipe mechanism 1. The large module 22 is movably mounted on the track 21 in the direction of pipe feeding. The first cylinder 23 is located on the side wall of the large module 22 near the upper pipe mechanism 1. A rod can be installed between the first cylinder 23 and the large module 22 to increase the distance between the track 21 and the end point of the upper pipe mechanism 1. The side plate 25 is fixedly mounted on the outer wall of the first cylinder 23 away from the upper pipe mechanism 1. The second cylinder 24 is connected to the piston rod of the first cylinder 23. The fixing block 26 is slidably mounted on the piston rod of the second cylinder 24. The connecting plate 27 is fixedly mounted on the side plate 25 near the cutting box 5. The gripper 28 is mounted on the fixing block 26 and the connecting plate 27. Understandably, when the remaining length of the pipe is very short, the stroke of cylinder 23 is insufficient to push the pipe to the cutting box 5. At this time, the large module 22 needs to move towards the cutting box 5 to further push the remaining pipe to the cutting box 5 for cutting.
[0027] Specifically, the gripper 28 includes a drive arm 281, an upper gripper 282, and a lower gripper 283. One side of the drive arm 281 is rotatably mounted on the fixed block 26, and the other side is rotatably connected to one end of the upper gripper 282. The upper gripper 282 is also rotatably mounted on the connecting plate 27. The upper gripper 282 is generally curved. The lower gripper 283 is fixedly mounted on the connecting plate 27. The gripping point of the lower gripper 283 is parallel to the bottom edge of the side plate 25. Furthermore, the connection points of the upper gripper 282 and the lower gripper 283 on the connecting plate 27 are on the same vertical line. Anti-slip teeth are provided at the bottom of the gripping point of the upper gripper 282 and the top of the gripping point of the lower gripper 283.
[0028] Specifically, the upper tube mechanism 1 is arranged in multiple arrays along the axis of the drive roller 15 to provide greater support for long tubes and improve conveying efficiency.
[0029] During use, when the upper pipe mechanism 1 transports the pipe to the limit post 34 via belt drive, the piston rod of cylinder 42 drives the straightening plate 43 to move upward, lifting the side of the pipe away from the cutting box 5. Then, cylinder 23 pushes it towards the cutting box 5, causing the lower clamp 283 to extend into the pipe and the upper clamp 282 to extend above the upper wall of the pipe. Then, cylinder 42 drives the straightening plate 43 to fall back, and the pipe falls down. Then, cylinder 24 drives the fixing block 26 to make the clamp 28 clamp the upper wall of the pipe. Cylinder 23 transports the pipe towards the cutting box 5. When the push stroke of cylinder 23 is insufficient, the large module 22 moves along the track 21 towards the cutting box 5, pushing the remaining part of the pipe towards the cutting box 5 for cutting.

The cutting process is not an improvement of this application and will not be described in detail. In addition, the ground support part in this application will not be described in detail and should not be considered as the mechanism in this application being in a state of being suspended in mid-air.
