Technical Field

[0001] This utility model relates to the field of pipe cutting technology, specifically a pipe cutting clamping tool. Background Technology

[0002] Plastic pipes are pipe materials made from plastic resin as the main raw material through processes such as extrusion and injection. During the processing of plastic pipes, cutting and clamping tools are needed to cut the plastic pipes.

[0003] A Chinese patent with authorization announcement number CN 218747990 U discloses a plastic pipe cutting fixture, including a worktable, a clamping mechanism mounted on the top of a raised base, and a cutting mechanism movably connected to the other side of the top of the worktable. The clamping mechanism includes a second mounting base with a second screw threaded to its top, and a telescopic rod mounted on one side of the top of the mounting base. The cutting mechanism includes a first mounting base with a cutting table mounted on it. The cutting table has a cutting groove, and an electric telescopic rod is mounted on the top of the first mounting base. An electric cutting wheel is mounted on the output end of the electric telescopic rod, and a protective cover is provided on the outside of the electric cutting wheel disc, which is located directly above the cutting groove. This utility model facilitates the clamping and rapid cutting of plastic pipes of different sizes, with high cutting continuity, easy material collection, and improved cutting efficiency. It can also absorb the plastic debris generated during cutting, avoiding environmental pollution.

[0004] Existing cutting and clamping fixtures have difficulty controlling the clamping force during the clamping process of plastic pipes. The plastic pipes are prone to slight deformation due to uneven force, resulting in poor uniformity of force on the plastic pipes. Therefore, a pipe cutting and clamping fixture is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a pipe cutting and clamping tool.

[0006] The technical solution adopted by this utility model to solve its technical problem is a pipe cutting and clamping fixture, including a base, a control panel mounted on the base, a clamping seat mounted on the base, and two sets of sliding grooves on the clamping seat. A double-ended screw is rotatably mounted on the inner wall of one of the sliding grooves. The threads on the double-ended screws are symmetrical and opposite in direction. A damping wheel is mounted on one end of the double-ended screw. Two sliders are symmetrically assembled in the sliding groove. Clamping blocks are mounted on the sliders. Adjacent clamping blocks are fixedly connected by a connecting plate. A cavity is opened inside the clamping block. Multiple plate grooves are opened on the inner wall of the cavity. Pressure plates are assembled in the plate grooves. Multiple rod holes are opened on the side wall of the clamping block. Limiting rods are assembled in the rod holes. Rubber is installed at the end of the limiting rod. A spring is installed between the limiting rod and the inner wall of the cavity. A lifting groove is provided on the inner wall of the cavity, and a lifting rod is slidably mounted on the inner wall of the lifting groove. The lifting rod is fixedly connected to the side walls of multiple pressure plates. An electric telescopic rod is installed on the inner wall of the lifting groove. The actuating rod of the electric telescopic rod is fixedly connected to the lifting rod. The electric telescopic rod is connected to the control panel through an internal circuit. During the movement of the plastic tube by the two rows of clamping blocks, the limiting rod will surround the plastic tube according to its shape. Then, multiple pressure plates press and fix all the limiting rods. At this time, the plastic tube is located between the fixed limiting rods, realizing the clamping and fixing of the plastic tube. This structure can avoid the plastic tube from undergoing slight deformation due to uneven force and is beneficial to improving the uniformity of force on the plastic tube.

[0007] Preferably, the clamping seat is equipped with two sets of first placement seats, with a cutting groove between the two sets of first placement seats. The base is equipped with two sets of second placement seats, on which plastic tubes are placed. A support frame is fixedly installed on the base, and a hydraulic cylinder is installed on the support frame. A protective cover is installed on the actuating rod of the hydraulic cylinder. A cutting blade is rotatably installed on the inner wall of the protective cover. A drive motor is installed on the side wall of the protective cover via a base. The output shaft of the drive motor is fixedly connected to the rotating shaft of the cutting blade. By operating the hydraulic cylinder, its actuating rod drives the protective cover to move vertically downward, and the protective cover drives the cutting blade to move vertically downward. At the same time, the drive motor drives the cutting blade to rotate at high speed, and the cutting blade quickly cuts the plastic tube. During this process, the two first placement seats provide stable support for both ends of the plastic tube at the cut, avoiding the plastic tube from tilting and causing a slanted cut, which helps to improve the flatness of the plastic tube cut.

[0008] The advantages of this utility model are:

[0009] 1. In this utility model, during the process of moving the two rows of clamping blocks towards the plastic tube, the limiting rods will surround the plastic tube according to its shape. Then, multiple pressure plates press and fix all the limiting rods. At this time, the plastic tube is located between the fixed limiting rods, thus achieving the clamping and fixing of the plastic tube. This structure can avoid the plastic tube from undergoing slight deformation due to uneven force, which is beneficial to improving the uniformity of force on the plastic tube.

[0010] 2. This utility model utilizes a hydraulic cylinder, whose actuator moves the protective cover vertically downwards. The protective cover then moves the cutting blade vertically downwards, while the drive motor rotates the cutting blade at high speed. The cutting blade quickly cuts the plastic tube. During this process, the two first placement seats provide stable support to both ends of the plastic tube at the cut, preventing the plastic tube from tilting and causing a slanted cut, thus improving the flatness of the plastic tube cut.

[0018] 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 scope of protection of the present utility model.

[0019] Please see Figure 1-4As shown, a pipe cutting and clamping fixture includes a base 1, a control panel 2 mounted on the base 1, and a clamping seat 3 mounted on the base 1. The clamping seat 3 has two sets of sliding grooves 4. A double-ended screw 5 is rotatably mounted on the inner wall of one of the sliding grooves 4. The threads on the double-ended screw 5 are symmetrically opposite in direction. A damping wheel 6 is mounted at one end of the double-ended screw 5. Two sliders 7 are symmetrically assembled inside the sliding groove 4. Clamping blocks 8 are mounted on the sliders 7. Adjacent clamping blocks 8 are fixedly connected by a connecting plate. A cavity 9 is formed inside the clamping block 8. Multiple plate grooves 10 are formed on the inner wall of the cavity 9. Plate grooves 10 are assembled within the plate grooves 10. There is a pressure plate 11, and multiple rod holes 12 are opened on the side wall of the clamping block 8. A limit rod 13 is installed in the rod hole 12. A rubber head 14 is installed at the end of the limit rod 13. A spring 15 is installed between the limit rod 13 and the inner wall of the cavity 9. A lifting groove 16 is opened on the inner wall of the cavity 9. A lifting rod 17 is slidably installed on the inner wall of the lifting groove 16. The lifting rod 17 is fixedly connected to the side wall of the multiple pressure plates 11. An electric telescopic rod 18 is installed on the inner wall of the lifting groove 16. The actuating rod of the electric telescopic rod 18 is fixedly connected to the lifting rod 17. The electric telescopic rod 18 is connected to the control panel 2 through an internal circuit.During operation, the existing cutting and clamping fixture has difficulty controlling the clamping force when clamping the plastic tube 25. The plastic tube 25 is prone to slight deformation due to uneven force, resulting in poor uniformity of force distribution. By placing the plastic tube 25 on the first placement seat 19 and the second placement seat 20, and then rotating the damping wheel 6, the double-ended screw 5 is driven to rotate. The double-ended screw 5 drives the two sliders 7 on it to move synchronously relative to each other. The double-ended screw 5 has self-locking property, which mainly depends on the relationship between the lead angle of the double-ended screw 5 and the equivalent friction angle at the engagement point of the sliders 7. When the lead angle of the double-ended screw 5 is less than the equivalent friction angle at the engagement point with the sliders 7, the mechanism has self-locking property. Then, the two sliders 7 drive the two rows of clamping blocks 8 to move synchronously relative to each other. The two rows of clamping blocks 8 move towards the plastic tube 25. Under the push of the spring 15, the limiting rod 13 on the clamping block 8 extends out of the clamping block 8. During the movement of the two rows of clamping blocks 8 towards the plastic tube 25, the limiting rod 13 is pushed into the cavity 9. Inside, the limiting rod 13 surrounds the plastic tube 25 according to its shape. When the two rows of clamping blocks 8 contact the plastic tube 25, the double-headed screw 5 stops rotating. At this time, the two rows of clamping blocks 8 limit the plastic tube 25, making the plastic tube 25 perpendicular to the cutting blade 23. At the same time, under the action of the spring 15, the clamping force is relatively small. Then, the control panel 2 controls the operation of the four electric telescopic rods 18. The actuating rods on them drive the lifting rod 17 to move vertically downward. The lifting rod 17 drives multiple pressure plates 11 to move vertically downward. The multiple pressure plates 11 press and fix all the limiting rods 13, realizing the positioning of the limiting rods 13. At this time, the plastic tube 25 is located between the fixed limiting rods 13, realizing the clamping and fixing of the plastic tube 25. The rubber head 14 on the limiting rod 13 can prevent the limiting rod 13 from causing wear on the outer wall of the plastic tube 25. This structure can prevent the plastic tube 25 from undergoing slight deformation due to uneven force, which is beneficial to improving the uniformity of force on the plastic tube 25.

[0020] Please see Figure 5As shown, the clamping base 3 is equipped with two sets of first placement seats 19, with a cutting groove between the two sets of first placement seats 19. The base 1 is equipped with two sets of second placement seats 20. Plastic tubes 25 are placed on the second placement seats 20 and the first placement seats 19. A support frame 21 is fixedly installed on the base 1, and a hydraulic cylinder 26 is installed on the support frame 21. A protective cover 22 is installed on the actuating rod of the hydraulic cylinder 26. A cutting blade 23 is rotatably installed on the inner wall of the protective cover 22. A drive motor 24 is installed on the side wall of the protective cover 22 via a machine base. The output shaft of the drive motor 24 is fixedly connected to the rotating shaft of the cutting blade 23. During operation, the existing cutting and clamping fixture has difficulty in stably cutting the plastic tube 25 during clamping, and is prone to... The oblique cut problem resulted in poor flatness of the cut of the plastic tube 25. By placing the plastic tube 25 on the first placement seat 19 and the second placement seat 20, and then clamping and fixing the plastic tube 25 with two rows of clamping blocks 8, the plastic tube 25 was stably placed. Then, the hydraulic cylinder 26 was operated, and its rod drove the protective cover 22 to move vertically downward. The protective cover 22 drove the cutting blade 23 to move vertically downward. At the same time, the drive motor 24 drove the cutting blade 23 to rotate at high speed. The cutting blade 23 quickly cut the plastic tube 25. During this process, the two first placement seats 19 provided stable support for both ends of the cut of the plastic tube 25, avoiding the problem of the plastic tube 25 tilting and oblique cut, which helped to improve the flatness of the cut of the plastic tube 25.

[0021] Working principle: Existing cutting and clamping fixtures have difficulty controlling the clamping force during the clamping process of plastic tube 25. The plastic tube 25 is prone to slight deformation due to uneven force distribution, resulting in poor uniformity of force distribution. By placing the plastic tube 25 on the first placement seat 19 and the second placement seat 20, and then rotating the damping wheel 6, the double-ended screw 5 is driven to rotate. The double-ended screw 5 drives the two sliders 7 on it to move synchronously relative to each other. The double-ended screw 5 has self-locking properties, which mainly depend on the relationship between the lead angle of the double-ended screw 5 and the equivalent friction angle at the engagement point of the sliders 7. When the lead angle of the double-ended screw 5 is less than the equivalent friction angle at the engagement point with the sliders 7, the mechanism has self-locking properties. Afterwards, the two sliders... Block 7 drives the two rows of clamping blocks 8 to move synchronously relative to each other. The two rows of clamping blocks 8 move towards the plastic tube 25. Under the push of the spring 15, the limiting rod 13 on the clamping block 8 extends out of the clamping block 8. During the movement of the two rows of clamping blocks 8 towards the plastic tube 25, the limiting rod 13 is pushed into the cavity 9. The limiting rod 13 will surround the plastic tube 25 according to its shape. When the two rows of clamping blocks 8 contact the plastic tube 25, the double-ended screw 5 stops rotating. At this time, the two rows of clamping blocks 8 limit the plastic tube 25, so that the plastic tube 25 is perpendicular to the cutting blade 23. At the same time, under the action of the spring 15, the clamping force is relatively small. Then, the control panel 2 controls the operation of the four electric telescopic rods 18, and the actuating rods on them drive... The lifting rod 17 moves vertically downwards, causing multiple pressure plates 11 to move vertically downwards as well. The pressure plates 11 press and fix all the limiting rods 13, thus positioning them. At this time, the plastic tube 25 is positioned between the fixed limiting rods 13, achieving clamping and fixing of the plastic tube 25. The rubber heads 14 on the limiting rods 13 prevent wear on the outer wall of the plastic tube 25. This structure prevents slight deformation of the plastic tube 25 due to uneven force, improving the uniformity of force distribution. Existing cutting and clamping fixtures struggle to stably cut the plastic tube 25 during clamping, easily resulting in oblique cuts. The plastic tube 25 has poor cut smoothness. By placing the plastic tube 25 on the first placement seat 19 and the second placement seat 20, and then clamping and fixing the plastic tube 25 with two rows of clamping blocks 8, the plastic tube 25 is stably placed. Then, the hydraulic cylinder 26 operates, and its rod drives the protective cover 22 to move vertically downward. The protective cover 22 drives the cutting blade 23 to move vertically downward. At the same time, the drive motor 24 drives the cutting blade 23 to rotate at high speed. The cutting blade 23 quickly cuts the plastic tube 25. During this process, the two first placement seats 19 provide stable support for both ends of the plastic tube 25 at the cut, avoiding the plastic tube 25 from tilting and causing a slanted cut, which helps to improve the smoothness of the plastic tube 25 cut.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
