[0026] Furthermore, the tail end cutting assembly 73 includes a second connection block 731, and two second connection blocks 731 are provided. One end of the two second connection blocks 731 is connected to the side wall of the first electric telescopic rod 71, and two hydraulic support rods 732 are symmetrically provided on both sides of the two second connection blocks 731. The other ends of the two hydraulic support rods 732 are respectively connected to the second cutter head 733. The hydraulic support rod 732 can accurately control the resistance between the second cutter head 733 and the inner wall of the pipe, ensuring that the second cutter head 733 can effectively clean the burrs on the inner wall of the pipe cut, and at the same time play a shaping role on the pipe cut to prevent the cut deformation and ensure the subsequent use performance of the pipe.

[0027] Furthermore, both ends of the second blade 733 are provided with blade edges, and an arc-shaped concave cutout is provided on the top of the second blade 733. The blade edges at both ends of the second blade 733 and the arc-shaped concave cutout on the top can realize multi-directional cleaning of burrs on the inner wall of the pipeline, improving cleaning efficiency and quality; while cleaning burrs, the arc-shaped concave cutout can also support the inner wall of the pipeline, further preventing deformation of the cutout and improving the overall quality of the pipeline after cutting.

[0028] Furthermore, a gear is provided on the power output shaft of the driving motor 2, and a gear ring is meshed on one side of the gear, and the gear ring is sleeved on the outer wall of the positioning channel 1. The meshing transmission of the gear and the gear ring can stably transmit the power of the driving motor 2 to the positioning channel 1, ensure the stability and reliability of the rotation of the positioning channel 1, thereby driving the heat pump pipeline 4 to rotate smoothly, providing stable working conditions for cutting and burr removal, and improving processing accuracy and efficiency.

[0029] Working principle: The first step is to install the positioning channel 1 in a fixed position, and then pass the heat pump pipe 4 through the inner cavity of the positioning channel 1. At this time, start multiple electric clamping rods 3, and the output ends of the multiple electric clamping rods 3 are in contact with the surface of the heat pump pipe 4, and the heat pump pipe 4 is clamped and fixed. Then, start the driving motor 2, and the gear is driven to rotate by the power output shaft of the driving motor 2. The positioning channel 1 is driven to rotate by the engagement of the gear with the gear ring on the outer wall of the positioning channel 1. When the positioning channel 1 rotates, the heat pump pipe 4 is driven to rotate synchronously by the electric clamping rod 3. The clamping of the heat pump pipe 4 by the multiple electric clamping rods 3 can prevent the positioning channel 1 from rotating and the heat pump pipe 4 from being offset during the rotation process, thereby improving the cutting stability and ensuring the cutting quality. In addition, a rubber sheet is provided at one end of the electric clamping rod 3 that is in contact with the heat pump pipe 4, so as to avoid the situation where the surface of the heat pump pipe 4 is clamped and damaged. The second step is to start the servo motor 52, and use the servo motor 52 to push the connecting rod 521 to extend and insert it into the tail end of the heat pump pipe 4. Since the cutting position of the saw blade 63 always remains unchanged, the value of the extension of the connecting rod 521 can be set as a fixed parameter. The personnel can set the extension parameters of the connecting rod 521 according to the length of the heat pump pipe 4 to ensure the first cutter head 723 and the second cutter head 733 have a good cutting effect on the burrs on the inner wall of the disconnected part of the heat pump pipe 4. When one end of the connecting rod 521 is extended to the specified length, the second cutter heads 733 on both sides are pushed to contact the inner wall of the heat pump pipe 4 by starting the hydraulic support rod 732. When the heat pump pipe 4 is When the cutting rotation is performed, the burrs at the disconnection point can be removed by the second blade head 733; in the synchronous state of completing the cutting of the heat pump pipe 4, the second blade head 733 can clean the burrs, thereby improving the efficiency of burr cleaning during the cutting process, and when the first blade head 723 and the second blade head 733 collide with the inner wall of the cutout of the heat pump pipe 4, it is possible to avoid the situation in which the cutout of the heat pump pipe 4 is deformed during the cutting process, play a shaping role, and avoid the probability of cutout deformation, and the arc-shaped concave cutout set on the second blade head 733 can also perform a secondary burr cleaning effect when it contacts the inner wall of the heat pump pipe 4, thereby improving the burr cleaning efficiency; The third step is to start the second electric telescopic rod 74, and through the contraction of the second electric telescopic rod 74, pull one end of the insertion rod 75 to insert into the inner cavity of the insertion slot opened on the vertical plate 724, and when the chamfered surface on the insertion rod 75 contacts the chamfered surface in the insertion slot, the first cutter head 723 is pushed to contact the inner cavity of the cut opening on the heat pump pipe 4. Similarly, when the heat pump pipe 4 rotates, the first cutter head 723 can clean the burrs in the inner cavity at the tail end of the broken surface, and the cutting groove set on the first cutter head 723 can also achieve the effect of secondary cleaning of the burrs.

[0030] Among them, compared with traditional cutting equipment, the heat pump pipe 4 needs to be cleaned up separately after cutting. The present equipment can clean up the internal burrs simultaneously during the process of cutting the heat pump pipe 4, thereby improving the cutting efficiency, reducing the processing steps, and ensuring that the construction personnel will not be injured by burrs during the transportation and handling of the cut heat pump pipe 4, thereby improving the safety of construction. Secondly, when the heat pump pipe 4 is rotating, the arc-shaped surfaces of the first blade head 723 and the second blade head 733 are set to contact the inner wall of the heat pump pipe 4, which can scrape out the burrs and support the inner wall at the same time, thereby shaping the inner wall of the heat pump pipe 4, avoiding the deformation of the incision caused by the saw blade 63 during the downward cutting process, and affecting the flow performance of the refrigerant or other fluids in the pipe.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
