[0002] The chipless plastic pipe cutting device is a specialized piece of equipment designed to address the challenges of chip contamination, material waste, and subsequent cleaning during the cutting process of plastic pipes. Its core principle is to achieve chipless (or minimal chip) cutting and smooth cuts by optimizing the cutting principle and structure. It is widely used in fields with high cleanliness requirements, such as food, medical, and precision piping.

[0003] Currently, when performing chipless cutting of plastic pipes, deviation is prone to occur. At the same time, fixing plastic pipes of different specifications is quite cumbersome when cutting them, resulting in low cutting efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a chipless cutting device for plastic pipes, which solves the problems mentioned in the background art, such as the tendency for deviation to occur during chipless cutting of plastic pipes, and the cumbersome fixing process when cutting plastic pipes of different specifications, resulting in low cutting efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chipless cutting device for plastic pipes, comprising a base, a fixed seat fixedly installed on the outer surface of the base, a cutting element fixedly installed inside the base, a servo motor provided on the outer surface of the fixed seat, a lead screw fixedly installed at the output end of the servo motor, an electric telescopic arm slidably connected to the outer surface of the lead screw, a bottom clamp fixedly installed at the output end of the electric telescopic arm, a connecting frame fixedly installed on the outer surface of the electric telescopic arm, an electric telescopic rod fixedly installed on the outer surface of the connecting frame, and a top clamp fixedly installed at the output end of the electric telescopic rod, the top clamp and the bottom clamp being arranged to clamp each other.

[0006] Preferably, the outer surface of the base has an opening, and a mounting base is provided on the outer surface of the base near the opening. A mounting frame is fixedly mounted on the outer surface of the mounting base, and a drive motor is provided on the outer surface of the mounting frame. A worm gear is fixedly mounted on the output end of the drive motor. A worm wheel is meshed with the outer surface of the worm gear, and a mounting plate is fixedly mounted on the outer surface of the worm wheel. The mounting plate is rotatably connected to the mounting frame. A sliding groove is provided on the outer surface of the mounting plate, and a sliding member is slidably connected to the outer surface of the sliding groove. A connecting plate is fixedly mounted on the outer surface of the mounting frame, and a limiting groove is provided on the outer surface of the connecting plate. A sliding block is fixedly mounted on the sliding member through the limiting groove, and a clamping member is fixedly mounted on the outer surface of the sliding block.

[0007] Preferably, the outer surface of the mounting base is provided with fixing bolts, and the mounting base is fixedly connected to the machine base by the fixing bolts. The outer surface of the clamp is fixedly installed with a clamping seat, and the outer surface of the connecting plate is fixedly installed with an auxiliary component. The outer surface of the auxiliary component is rotatably connected with a fixing component, and the fixing component is rotatably connected to the clamping seat.

[0008] Preferably, both the bottom clamp and the top clamp are arc-shaped, and both the bottom clamp and the top clamp are equipped with pressure sensors inside, and the connecting frame is C-shaped.

[0009] Preferably, the clamps are arranged in a three-ring array, and the fixing members are hexagonal.

[0010] Preferably, a top is fixedly installed on the outer surface of the base, the opening is opened on both sides of the base and the opening is connected to the mounting base, and a controller is provided on the outer surface of the base. The controller is electrically connected to the servo motor, drive motor, electric telescopic arm, pressure sensor and electric telescopic rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This chipless plastic pipe cutting device uses a servo motor to drive the lead screw to rotate, which in turn drives the electric telescopic arm to slide precisely along the lead screw, thereby adjusting the position of the bottom clamp. At the same time, the electric telescopic rod on the connecting frame drives the top clamp to extend and retract, forming a counter-clamping action with the bottom clamp. Combined with the telescopic function of the electric telescopic arm, the clamping distance is adjusted, thus ensuring that the pipe does not deviate or shake during the cutting process, improving the cutting accuracy and stability.

[0012] 2. This chipless plastic pipe cutting device uses a drive motor to rotate a worm gear. The worm gear meshes with a worm wheel, causing the worm wheel to drive the mounting plate to rotate around the mounting frame. When the mounting plate rotates, the groove on its outer surface causes the sliding component to slide. At the same time, the sliding component is constrained by the limiting groove on the outer surface of the connecting plate, forcing the sliding block to move synchronously in the radial direction. This, in turn, causes the clamp to retract or open. The port cooperates with the mounting base to provide a passage for the pipe to pass through, allowing the pipe to enter the clamping range of the clamp. This achieves high-precision radial positioning for pipe conveying and cutting, avoids cutting errors caused by clamping offset, and improves the perpendicularity and consistency of the cut.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please refer to Figures 1-4. A chipless cutting device for plastic pipes includes a base 1, a fixed seat 4 fixedly installed on the outer surface of the base 1, a cutting element 3 fixedly installed inside the base 1, a servo motor 5 provided on the outer surface of the fixed seat 4, a lead screw 6 fixedly installed at the output end of the servo motor 5, an electric telescopic arm 7 slidably connected to the outer surface of the lead screw 6, a bottom clamp 8 fixedly installed at the output end of the electric telescopic arm 7, a connecting frame 9 fixedly installed on the outer surface of the electric telescopic arm 7, an electric telescopic rod 10 fixedly installed on the outer surface of the connecting frame 9, a top clamp 11 fixedly installed at the output end of the electric telescopic rod 10, and the top clamp 11 and the bottom clamp 8 are arranged to clamp each other.

[0017] Specifically, the servo motor 5 drives the lead screw 6 to rotate, which in turn drives the electric telescopic arm 7 to slide precisely along the lead screw 6, thereby adjusting the position of the bottom clamp 8. At the same time, the electric telescopic rod 10 on the connecting frame 9 drives the top clamp 11 to extend and retract, forming a counter-clamping action with the bottom clamp 8. This, combined with the telescopic function of the electric telescopic arm 7, adjusts the clamping distance, thereby ensuring that the pipe does not deviate or shake during the cutting process, and improving the cutting accuracy and stability.

[0018] In the embodiment: both the bottom clamp 8 and the top clamp 11 are arc-shaped, and pressure sensors are provided inside both the bottom clamp 8 and the top clamp 11. The connecting frame 9 is C-shaped.

[0019] Specifically, the bottom clamp 8 and the top clamp 11 are designed in an arc shape, and their curved surfaces can fit against the outer surface of the circular plastic tube, increasing the clamping contact area. The internal pressure sensor monitors the pressure value in real time during the clamping process, forming pressure feedback. The C-shaped connecting frame 9 provides rigid support for the top clamp 11 and the electric telescopic rod 10, while reserving operating space for inserting or removing the tube. The arc structure ensures that the tube is subjected to uniform force during clamping, avoiding local compression deformation. The pressure sensor adjusts the clamping force through feedback to prevent overpressure from damaging the tube or underpressure from causing slippage. The C-shaped connecting frame 9 ensures the stability of the clamping mechanism while improving the ease of operation, ultimately achieving adaptive, non-destructive, and stable clamping of plastic tubes of different diameters, providing a reliable positioning basis for subsequent chipless cutting.

[0020] In this embodiment: the outer surface of the base 1 is fixedly installed with the top 2, the openings 12 are opened on both sides of the base 1, the openings 12 are connected to the mounting base 13, the outer surface of the base 1 is provided with a controller, and the controller is electrically connected to the servo motor 5, the drive motor 15, the electric telescopic arm 7, the pressure sensor and the electric telescopic rod 10.

[0021] Specifically, the top of the machine 2 provides structural protection and enclosed support for the base 1, ensuring a stable operating environment for the internal cutting components 3; the two side openings 12 connect with the mounting base 13, forming a through channel for pipe entry and exit, ensuring that the pipe can be accurately transported to the cutting area along a preset path; the controller, as the core control hub, receives the clamping pressure signal from the pressure sensor in real time through electrical connection, and sends instructions to the servo motor 5, drive motor 15, electric telescopic arm 7, and electric telescopic rod 10 to realize the linkage control of clamping force adjustment, position movement, and telescopic action. The top of the machine 2 improves the safety and structural stability of the equipment operation; the openings 12 ensure the smooth transport of pipes of different lengths; the controller, through centralized intelligent control, enables the clamping, feeding, and cutting processes to automatically coordinate according to preset logic, reducing manual intervention, and ultimately achieving automated and precise control of the cutting process, improving the ease of operation and reliability of the equipment.

[0022] Working principle: A fixed base 4 is fixedly installed on the outer surface of the base 1. A cutting element 3 is fixedly installed inside the base 1. A servo motor 5 is installed on the outer surface of the fixed base 4. A lead screw 6 is fixedly installed at the output end of the servo motor 5. An electric telescopic arm 7 is slidably connected to the outer surface of the lead screw 6. A bottom clamp 8 is fixedly installed at the output end of the electric telescopic arm 7. A connecting frame 9 is fixedly installed on the outer surface of the electric telescopic arm 7. An electric telescopic rod 10 is fixedly installed on the outer surface of the connecting frame 9. A top clamp 11 is fixedly installed at the output end of the electric telescopic rod 10. The bottom clamp 8 is clamped against the bottom clamp 8. The servo motor 5 drives the lead screw 6 to rotate, which drives the electric telescopic arm 7 to slide precisely along the lead screw 6, thereby adjusting the position of the bottom clamp 8. At the same time, the electric telescopic rod 10 on the connecting frame 9 drives the top clamp 11 to extend and retract, forming a counter-clamping action with the bottom clamp 8. The clamping distance is adjusted in conjunction with the telescopic function of the electric telescopic arm 7. Compared with related technologies, the chip-free cutting device for plastic pipes provided by this utility model has the following beneficial effects: thereby ensuring that the pipe does not deviate or shake during the cutting process, and improving the cutting accuracy and stability.

[0023] Example 2: Please refer to Figures 1-4. The outer surface of the base 1 has an opening 12. A mounting base 13 is provided on the outer surface of the base 1 near the opening 12. A mounting frame 14 is fixedly mounted on the outer surface of the mounting base 13. A drive motor 15 is provided on the outer surface of the mounting frame 14. A worm gear 16 is fixedly mounted on the output end of the drive motor 15. A worm wheel 17 is meshed with the outer surface of the worm gear 16. A mounting plate 18 is fixedly mounted on the outer surface of the worm wheel 17. The mounting plate 18 is rotatably connected to the mounting frame 14. A sliding groove 19 is provided on the outer surface of the mounting plate 18. A sliding member 20 is slidably connected to the outer surface of the sliding groove 19. A connecting plate 21 is fixedly mounted on the outer surface of the mounting frame 14. A limiting groove 22 is provided on the outer surface of the connecting plate 21. A sliding block 23 is fixedly mounted on the sliding member 20 through the limiting groove 22. A clamping member 24 is fixedly mounted on the outer surface of the sliding block 23.

[0024] Specifically, the drive motor 15 drives the worm gear 16 to rotate, and the worm gear 16 meshes with the worm wheel 17 to drive the mounting plate 18 to rotate around the mounting frame 14. When the mounting plate 18 rotates, the sliding groove 19 on its outer surface drives the sliding member 20 to slide. At the same time, the sliding member 20 is constrained by the limiting groove 22 on the outer surface of the connecting plate 21, which forces the sliding seat 23 to move synchronously in the radial direction, thereby driving the clamp 24 to retract or open. The through port 12 cooperates with the mounting seat 13 to provide a passage for the pipe to enter, so that the pipe can enter the clamping range of the clamp 24. This achieves high-precision radial positioning for pipe conveying and cutting, avoids cutting errors caused by clamping offset, and improves the perpendicularity and consistency of the cut.

[0025] In the embodiment: the outer surface of the mounting base 13 is provided with fixing bolts, and the mounting base 13 is fixedly connected to the machine base 1 by fixing bolts. The outer surface of the clamp 24 is fixedly installed with a clamping seat 25. The outer surface of the connecting plate 21 is fixedly installed with an auxiliary component 26. The outer surface of the auxiliary component 26 is rotatably connected with a fixing component 27. The fixing component 27 is rotatably connected to the clamping seat 25.

[0026] Specifically, the mounting base 13 is rigidly connected to the machine base 1 by fixing bolts. The preload of the bolts ensures that the connection between the mounting base 13 and the machine base 1 is stable, avoiding relative displacement due to vibration during clamping and providing a stable installation reference for the entire clamping mechanism. The clamping base 25, the fixing member 27, and the auxiliary member 26 form a rotating linkage structure. The auxiliary member 26 is fixed to the connecting plate 21. The two ends of the fixing member 27 are rotatably connected to the auxiliary member 26 and the clamping base 25, respectively. When the clamping member 24 moves radially with the slide 23, the fixing member 27 rotates around the auxiliary member 26 and constrains the movement trajectory of the clamping base 25, preventing the clamping member 24 from lateral shaking or displacement during clamping.

[0027] In this embodiment: the clamps 24 are arranged in a three-ring array, and the fasteners 27 are hexagonal.

[0028] Specifically, the clamps 24 are arranged in a three-ring array, forming a stable "centering support structure" by evenly distributing the three points around the circumference. When the three clamps 24 move synchronously in the radial direction, their arc contact surfaces can form three-point tangential contact with the outer surface of the pipe. Based on the principle of triangle stability, the pipe is automatically centered and positioned, avoiding the pipe offset or tilting problems that are easily caused by single-point or two-point clamping. The fixing part 27 is hexagonal, which enhances its own structural rigidity by utilizing the mechanical properties of the polygonal structure. The symmetrical structure of the hexagon ensures that the corners of the fixing part 27 are evenly stressed when it is rotatably connected with the auxiliary part 26 and the clamp 25, reducing deformation caused by local stress concentration. At the same time, it provides a clear positioning reference for assembly and ensures the installation accuracy of the rotating linkage structure.

[0029] Working principle: A through-hole 12 is provided on the outer surface of the base 1. A mounting seat 13 is provided on the outer surface of the base 1 near the through-hole 12. A mounting bracket 14 is fixedly mounted on the outer surface of the mounting seat 13. A drive motor 15 is provided on the outer surface of the mounting bracket 14. A worm gear 16 is fixedly mounted on the output end of the drive motor 15. A worm wheel 17 is meshed with the outer surface of the worm gear 16. A mounting plate 18 is fixedly mounted on the outer surface of the worm wheel 17. The mounting plate 18 is rotatably connected to the mounting bracket 14. A sliding groove 19 is provided on the outer surface of the mounting plate 18. A sliding member 20 is slidably connected to the outer surface of the sliding groove 19. A connecting plate 21 is fixedly mounted on the outer surface of the mounting bracket 14. Because a limiting groove 22 is provided on the outer surface of the connecting plate 21, a sliding block 23 is fixedly mounted on the sliding member 20 through the limiting groove 22. The outer surface of the sliding block 23 is fixedly mounted on the sliding block 23. The device is equipped with a clamp 24. The drive motor 15 drives the worm gear 16 to rotate. The worm gear 16 meshes with the worm wheel 17, causing the worm wheel 17 to drive the mounting plate 18 to rotate around the mounting frame 14. When the mounting plate 18 rotates, the sliding groove 19 on its outer surface drives the sliding member 20 to slide. At the same time, the sliding member 20 is constrained by the limiting groove 22 on the outer surface of the connecting plate 21, forcing the sliding seat 23 to move synchronously in the radial direction. This causes the clamp 24 to retract or open. The through port 12 cooperates with the mounting seat 13 to provide a passage for the pipe to enter, allowing the pipe to enter the clamping range of the clamp 24. Compared with related technologies, the chipless cutting device for plastic pipes provided by this utility model has the following beneficial effects: it achieves high-precision radial positioning for pipe conveying and cutting, avoids cutting errors caused by clamping offset, and improves the perpendicularity and consistency of the cut.
