Description

Technical Field

[0001] This utility model relates to the field of fixed-length cutting mechanisms, specifically to a fixed-length cutting mechanism for pipe fittings. Background Technology

[0002] A pipe fitting length cutting mechanism is an automated or semi-automated device specifically designed to precisely cut pipes (such as metal pipes, plastic pipes, composite pipes, etc.) to a preset length.

[0003] A search revealed a utility model pipe fitting length-cutting mechanism with announcement number CN223099339U, comprising: a fixed plate and an electric push rod on the surface of a support base; a clamping frame on the lifting end of the electric push rod; a support plate on one end of a vertical plate; a support screw inside the support plate; a scale plate on the side of the support plate; a drive motor on the end face of the support screw; a base screwed onto the surface of the support screw; a second electric push rod at the bottom of the base; and a cutting device on the lifting end of the second electric push rod. The advantages are: firstly, the drive motor can be started to rotate the support screw, thereby displacing the base screwed onto the support screw, which in turn moves the cutting device. The displacement distance of the cutting device can be adjusted according to the scale plate, thus facilitating accurate control of the pipe cutting length. It eliminates the need for measuring and marking each group of pipes before cutting, improving pipe cutting efficiency.

[0004] The pipe length cutting mechanism in the aforementioned patent is only convenient for pushing and cutting grout, but it lacks a rotating structure. When cutting directly, the blade applies a vertical force to the pipe, which can easily cause burrs, edge collapse, or deformation on the end face, and also accelerates the wear of the blade.

[0005] Therefore, it is necessary to invent a pipe fitting fixed-length cutting mechanism to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a pipe length cutting mechanism. By inserting the pipe into the limiting frame, the bolts on the outside of the limiting frame are rotated to push the clamping plate to clamp the outside of the pipe. At the same time, the other end of the pipe is also clamped inside the cutting seat. When cutting is required, the servo motor switch is turned on to drive the synchronous wheel to rotate. The rotation of the synchronous wheel drives the external synchronous belt and the limiting frame to rotate in the support seat, so that the pipe rotates for cutting. At the same time, during the cutting process, the pressure plate on the other side of the cutting blade assembly is attached to the outside of the pipe to enhance the positioning and cutting performance. This solves the problem that the pipe length cutting mechanism in the aforementioned patent in the background art is only convenient for pushing and cutting grout, but lacks a rotating structure. When cutting directly, the blade applies a vertical force to the pipe, which can easily cause burrs, collapse, or deformation on the end face, and also accelerates the wear of the blade.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pipe fitting fixed-length cutting mechanism, including a cutting seat for placing pipes for cutting; The graduated bars are all set on the outside of the cutting seat for cutting pipes to a fixed length. A support base is fixedly connected to the front inner side of the cutting seat. A servo motor is fixedly connected to the lower inner side of the support base. A synchronous pulley is fixedly connected to the output end of the servo motor. A synchronous belt is sleeved on the outside of the synchronous pulley. A limiting frame is sleeved on the other side of the inside of the synchronous belt. Bolts pass through the outside of the limiting frame. A clamping plate is rotatably connected to the front end of the bolt. A drive motor is located at one end below the cutting seat. A lead screw is fixedly connected to the output end of the drive motor. A movable frame is connected to the external thread of the lead screw. A cylinder is fixedly installed at the upper end of the movable frame. A connecting plate is fixedly connected to the output end of the cylinder. A cutting blade assembly is fixedly installed below the connecting plate. A connecting seat is fixedly connected to the other side below the connecting plate.

[0010] Preferably, movable rods are fixedly connected to the upper two sides of the connecting plate, and the movable rods are slidably connected to the movable frame.

[0011] Preferably, a telescopic rod is movably inserted inside the connecting seat, a pressure plate is fixedly connected to the lower end of the telescopic rod, a spring is sleeved on the outside of the telescopic rod, and ball bearings are rotatably connected to the lower part of the pressure plate.

[0012] Preferably, the cutting seat has a push plate inside, an electric push rod is fixedly installed below the push plate, and the surface of the push plate is provided with ball bearings.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention, through the arrangement of a support base, servo motor, synchronous pulley, synchronous belt, limiting frame, clamping plate, and pressure plate, not only clamps the pipe fitting during the cutting process but also enables rotational cutting, thereby enhancing the cutting effect. The pipe fitting is inserted into the limiting frame, and then the bolts on the outside of the limiting frame are rotated to push the clamping plate to clamp the pipe fitting externally. Simultaneously, the other end of the pipe fitting is clamped inside the cutting base. When cutting is required, the servo motor switch is turned on, driving the synchronous pulley to rotate.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-5 The illustrated pipe fitting length cutting mechanism includes a cutting seat 1 for placing the pipe cutter. The scale bar 2 is set on the outside of the cutting seat 1 for cutting pipes to a fixed length. The front inner side of the cutting seat 1 is fixedly connected to the support seat 3. The lower inner side of the support seat 3 is fixedly connected to the servo motor 4. The output end of the servo motor 4 is fixedly connected to the synchronous pulley 5. The outside of the synchronous pulley 5 is fitted with a synchronous belt 6. The other side of the inside of the synchronous belt 6 is fitted with a limit frame 7. The outside of the limit frame 7 is pierced by bolts 9. The front end of the bolts 9 is rotatably connected to the clamping plate 10. A drive motor 12 is located at one end below the cutting seat 1. A lead screw 13 is fixedly connected to the output end of the drive motor 12. A movable frame 14 is threaded onto the external end of the lead screw 13. A cylinder 15 is fixedly installed at the upper end of the movable frame 14. A connecting plate 16 is fixedly connected to the output end of the cylinder 15. A cutting blade assembly 17 is fixedly installed below the connecting plate 16. A connecting seat 18 is fixedly connected to the other side below the connecting plate 16. A pressure plate 20 is installed below the connecting seat 18. The tube is inserted into the limiting frame 7. Next, the bolt 9 on the outside of the limiting frame 7 is rotated to push the clamping plate 10 to clamp the outside of the pipe. At the same time, the other end of the pipe is also clamped inside the other end of the cutting seat 1. When cutting is required, the servo motor 4 is turned on to drive the synchronous wheel 5 to rotate. The rotation of the synchronous wheel 5 drives the external synchronous belt 6 and the limiting frame 7 to rotate in the support seat 3, so that the pipe rotates and is cut. At the same time, during the process of the cutting blade assembly 17, the pressure plate 20 on the other side of the cutting blade assembly 17 is attached to the outside of the pipe to enhance the positioning and cutting performance.

[0019] like Figure 2 and Figure 3 As shown, a slider 8 is fixedly connected to the outside of the limiting frame 7, and a groove matching the slider 8 is opened inside the support base 3. When the limiting frame 7 rotates inside the support base 3, the external slider 8 is limited and slids in the groove inside the support base 3, which enhances the stability of the rotation of the limiting frame 7.

[0020] like Figure 3 As shown, sliding rods 11 are fixedly connected to the upper two sides of the clamping plate 10. The sliding rods 11 are connected to the limiting frame 7 through the plate. By rotating the bolts 9 on the upper side of the limiting frame 7, the clamping plate 10 is pushed to move. The sliding rods 11 on the upper two sides of the clamping plate 10 are used to enhance the stability of the clamping plate 10 during the movement process.

[0021] like Figure 4 As shown, movable rods are fixedly connected to the upper two sides of the connecting plate 16. The movable rods are slidably connected to the moving frame 14. When the cylinder 15 pushes the connecting plate 16 and the cutting blade assembly 17 below to stick to the outside of the pipe, the movable rod on the upper side of the connecting plate 16 slides in the moving frame 14, thereby enhancing the stability of the connecting plate 16 during the lifting process.

[0022] like Figure 4 and Figure 5As shown, a telescopic rod 19 moves through the interior of the connecting seat 18. A pressure plate 20 is fixedly connected to the lower end of the telescopic rod 19. A spring 21 is sleeved on the outside of the telescopic rod 19. Ball bearings 22 are rotatably connected to the bottom of the pressure plate 20. When the connecting plate 16 descends, it drives the connecting seat 18 and the pressure plate 20 below to descend, so that the pressure plate 20 and the ball bearings 22 are attached to the outside of the pipe. The pipe will rotate during the cutting process. Therefore, the ball bearings 22 are attached to the outside of the pipe. As the pipe rotates, the ball bearings 22 rotate with it, thereby avoiding obstruction during the rotation of the pipe. At the same time, the spring 21 above the pressure plate 20 squeezes the pressure plate 20, so that the pressure plate 20 can be pressed tightly against the outer wall of the pipe.

[0023] like Figure 1 As shown, the cutting seat 1 is equipped with a push plate 23 inside, and an electric push rod is fixedly installed below the push plate 23. The surface of the push plate 23 is equipped with balls 22. According to the height of the pipe clamping, the push plate 23 is pushed by opening the electric push rod, so that the push plate 23 is attached to the bottom of the pipe, thereby enhancing the stability of the pipe cutting process.

[0024] The working principle of this utility model is as follows: First, connect the external power supply. Then, insert the pipe into the limiting frame 7. Next, push the entire pipe into the other end of the cutting seat 1. Then, rotate the two sets of bolts 9 inside the limiting frame 7, so that the bolts 9 push the clamping plate 10 to stick to the outside of the pipe for clamping and positioning. The other end of the cutting seat 1 is also equipped with a clamping plate 10 to clamp one end of the pipe. Then, turn on the electric push rod switch below the push plate 23, so that the push plate 23 sticks to the bottom of the pipe. Then, according to the required cutting length of the pipe, turn on the drive motor 12 switch, so that the lead screw 13 rotates. The rotation of the lead screw 13 drives the entire external moving frame 14 to move in front of the scale strip 2 outside the cutting seat 1, so that it moves to the cutting position and then... Turn on the servo motor 4 inside the support base 3 to drive the synchronous wheel 5 to rotate. The rotation of the synchronous wheel 5 drives the external synchronous belt 6 and the limit frame 7 to rotate inside the support base 3, causing the pipe to rotate. Then, turn on the cylinder 15 to push the connecting plate 16 and the cutting blade assembly 17 to descend. The cutting blade assembly 17 is turned on and rotates. As the connecting plate 16 descends, it drives the connecting base 18 and the pressure plate 20 below to descend, so that the pressure plate 20 and the ball bearing 22 are attached to the outside of the pipe. At the same time, the spring 21 above the pressure plate 20 squeezes the pressure plate 20, so that the pressure plate 20 and the ball bearing 22 can stick tightly to the outer wall of the pipe. Finally, the cutting blade assembly 17 cuts the rotating pipe. In this way, the use of the pipe fixed length cutting mechanism is completed.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, 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.
