[0043] Specifically, after the steel pipe is conveyed to the rear side of the rack 1 by the conveying assembly and clamped and fixed in the fixed box 2, according to the position and precision requirement of the steel pipe to be cut, the servo motor two 303 at the rear side of the fixed box 2 is started, and the gear 305 rotates in the installation groove 304. Since the gear 305 is engaged with the rack 306 fixed at the top rear side of the rack 1, with the rotation of the gear 305, the fixed box 2 moves left and right on the rack 1, and the guide column 301 is embedded in the guide groove 302 to provide accurate guidance for the left and right movement of the fixed box 2, so that the fixed box 2 does not deviate or shake during movement. The rotation angle and number of turns of the gear 305 are accurately controlled by the servo motor two 303, so as to realize accurate positioning movement of the fixed box 2 and move the steel pipe to the accurate cutting position of the cutting tool.

[0044] Referring to Figure 1 , Figure 2 and Figure 4 , a plurality of lamp holders 21 are fixedly connected to the left and right sides of the rack 1, and the away sides of the plurality of lamp holders 21 are fixedly connected with illuminating lamps 22. The illuminating lamps 22 are used for illuminating the surroundings of the device in a dark environment. The front side of the fixed box 2 is fixedly connected with a monitor 24, which is used for monitoring the surroundings of the device. The left side of the monitor 24 is fixedly connected with a buzzer 25, which is used for reminding the operator when there is an emergency situation around the device. The outer wall right end of the rotating shell 6 is fixedly connected with a sealing ring 26, which can prevent dust from entering the fixed box 2 from the connection between the rotating shell 6 and the fixed box 2. The sealing ring 26 is designed in a ring shape. The bottom of the rack 1 is fixedly connected with a plurality of rubber pads 23, and the bottom ends of the plurality of rubber pads 23 are ground.

[0046] Working principle: When the transmission belt 18 rotates, the support frame 19 moves, allowing the steel pipe to smoothly approach the fixed box 2 at the rear side of the rack 1, preparing for subsequent fixation. The servo motor one 8 starts to drive the gear one 9 to rotate. The gear one 9 is engaged with the gear two 10, which is fixed at the top end of the bidirectional screw 11. The bidirectional screw 11 rotates synchronously. Since the threads on the upper and lower ends of the bidirectional screw 11 are opposite in direction, the two clamping strips 13 connected with the bidirectional screw 11 move up and down in opposite directions under the guidance of the sliding groove 12. The rubber elastic blocks 15 on the clamping strips 13 first contact the steel pipe, using the rubber elastic properties to play a buffering and damping role, avoiding rigid contact that may cause the steel pipe to shift or be damaged. At the same time, the pressure sensor 16 detects the pressure of the clamping strips 13 on the steel pipe in real time, so as to monitor and adjust the clamping force, ensuring stable clamping without damaging the steel pipe due to excessive pressure. The two clamping strips 13 apply pressure to the steel pipe from the outside, while the support module 17 provides support from the inside of the steel pipe. Through the internal and external dual-action force, the steel pipe is firmly clamped and fixed. The dust prevention block 14 prevents dust from entering the rotating shell 6 from the sliding groove 12, protecting the internal transmission components of the rotating shell 6 from normal operation. After the rotating motor 5 is started, the rotating shell 6 drives the clamped and fixed steel pipe to rotate synchronously, providing stable rotary power for subsequent cutting processing;

[0047] And, the servo motor two 303 as a power source, after starting to drive rotating gear 305 rotation, and the installation groove 304 provides a safe rotating space for rotating gear 305, also plays a certain support and protection effect, rotating gear 305 with rack 306 fixed on the top rear side of the rack 1 meshing, and the rack 306 is fixed on the rack 1, therefore fixed box 2 generates relative to the left and right direction of the movement of the rack 1, the guide column 301 both ends are fixedly connected to the inner wall of the rack 1, the guide groove 302 is opened in the middle of the fixed box 2, and the guide column 301 is embedded in the guide groove 302, forms a guide mechanism, when the fixed box 2 moves on the rack 1, the guide column 301 slides in the guide groove 302, effectively ensures the linearity and stability of the fixed box 2 movement, avoids the fixed box 2 to occur deviation or sway in the moving process, because the transmission ratio of rotating gear 305 and rack 306 is fixed, therefore through the accurate control of the rotation of servo motor two 303, the accurate control of the moving distance of fixed box 2 can be realized, so that the fixed box 2 can be accurately positioned to the required position, the steel pipe clamped in the box is accurately moved to the cutting position of the cutting tool, meets the position and precision requirement of accurate cutting of steel pipe.

[0048] Finally, it should be noted that: the above is only the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing detailed description of the present application, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
