[0034] It can be understood by those skilled in the art that the height of the third clamping member 707 is changed by extending or retracting the output end of the fourth electric push rod 706; the fourth screw 702 is driven to rotate by the output end of the fourth servo motor 704, so that the two groups of second movable blocks 705 are moved closer to or farther from each other, driving the two groups of third clamping members 707 to move closer to or farther from each other.

[0035] Working principle and use process of the device: In real life, the water conservancy pipeline 101 includes a main pipeline and branch pipelines, such as Fig.17 As shown ( Fig.17 101 is a top view of the water conservancy pipeline 101). In water conservancy projects, in order to control the flow direction of water, valves are usually installed on the branch pipelines and on the main pipelines near the branch pipelines. That is, the water conservancy pipeline 101 is cut at the E-1 or E-2 position, not only Fig.17 A position, all positions to be cut on the main pipe are recorded as E-1, and all positions to be cut on the branch pipes are recorded as E-2. The length cut is the length of the valve, thereby reserving the installation position of the valve. First, the clamping mechanism 2 clamps the two ends of the main pipe of the water conservancy pipe 101. The purpose of this is to lift the water conservancy pipe 101 so that it does not fit with the top of the body 1; The cutting step of the present invention is to cut along the outer surface of the water conservancy pipeline 101 from right to left in sequence, and first cut the branch pipeline E-2 section, and then cut the main pipeline E-1 section. Fig.17When marking the E-2 section, first, the fixing mechanism 3 clamps the main pipe, and the first drive motor 104, the second drive motor 106 and the telescopic mechanism 4 are used in coordination to make the position of the second connecting plate 103 match the branch pipe. Secondly, the output end of the second electric push rod 506 drives the connecting piece 507 to move downward, so that the height of the connecting piece 507 matches the height of the branch pipe. The output end of the second stepping motor 504 drives the second screw rod 502 to rotate, driving the connecting piece 507 to move close to the branch pipe, and the branch pipe is located inside the connecting piece 507. The output end of the third electric push rod 513 drives the cutting knife 515 to approach the branch pipe, and with the cooperation of the cutting motor 516 and the first transmission motor 509, the cutting knife 515 is in a rotating state and rotates around the center of the branch pipe, thereby achieving cutting. It is worth noting that when cutting at E-2-A, the terminal pipe of the branch pipe will inevitably fall due to the lack of clamping. Therefore, the present invention designs a lifting mechanism 7. When cutting at E-2-A, the two sets of third clamping members 707 also keep clamping the terminal tube of the branch pipe. After the cutting at E-2-A is completed, the cutting mechanism 5 is reset, and the output end of the fourth electric push rod 706 drives the terminal tube of the branch pipe to move upward, and then the output end of the second cylinder 605 drives the second grinding disc 608 to move downward, and the output end of the third cylinder 607 drives the second grinding disc 608 to approach the cutting end face of the terminal tube of the branch pipe, and drives the second grinding disc 608 to rotate through the output end of the second transmission motor 609, The cut end face is polished, and when cutting at E-2-B, the lifting mechanism 7 is not working and is in the original position. After the cutting at E-2-B is completed, the pipe section consistent with the valve length falls, and then the first grinding disc 604 is driven downward by the output end of the first cylinder 601, and the output end of the grinding motor 603 drives the first grinding disc 604 to rotate, so that the cut end face of the branch pipe connected to the main pipe is polished, so that the installation surfaces of the two ends of the pipes that are subsequently in contact with the valve are free of burrs, which is convenient for installation and improves efficiency; Similarly, cut the E-1 section of the main pipeline, following the same steps as the E-2 section. It is worth noting that when cutting the first E-1 section on the right side of the main pipeline, for example Fig.17 At E-1-B in the middle, since the right end of the water conservancy pipe 101 is in a clamped state, it is not convenient to grind the end face after cutting. At this time, the two groups of third clamps 707 also keep clamping the main pipe, and the two groups of first clamps 209 on the right are released, and are also polished by the second grinding disc 608. The present invention also has a noteworthy design. When the fixing mechanism 3 is released, the two groups of third clamps 707 in the lifting mechanism 7 are clamped, and the telescopic mechanism 4 is extended. When the first connecting plate 102 reaches a certain position, the rear fixing mechanism 3 clamps, the lifting mechanism 7 does not clamp, and the telescopic mechanism 4 retracts, so that the position of the cutting mechanism 5 can also be changed.
