[0033] Reference Figure 1-5This utility model provides an embodiment of a pipe cutting device, including a base 1, a frame 2 fixedly connected to the top of the base 1, an electric push rod 3 fixedly connected to the frame 2, and a lifting frame 4 fixedly connected to the output end of the electric push rod 3. The frame 2 is L-shaped, and the lifting frame 4 is located at its inner top position. When the electric push rod 3 is running, it can drive the lifting frame 4 to descend. A cutting frame 5 is arranged below the lifting frame 4, and a rotating shaft 6 is fixedly connected to the top of the cutting frame 5. The rotating shaft 6 is rotatably connected to the lifting frame 4, and the connection position between the rotating shaft 6 and the lifting frame 4 is positioned and installed by a bearing. A driving mechanism is provided inside the lifting frame 4, which can drive the rotating shaft 6 to rotate, and the rotating shaft 6 drives the cutting frame 5 to rotate, thereby adjusting the cutting angle of the pipe to meet different tilt angles. For pipe cutting requirements, a mounting recess 13 is provided on one side of the cutting frame 5, and a cover frame 14 is provided inside the mounting recess 13. A positioning groove 15 is provided at the corresponding position between the inner wall of the mounting recess 13 and the outer surface of the cover frame 14. A motor 16 is provided on the cutting frame 5. A cutting blade 17 is fixedly connected to the output end of the motor 16 and located in the positioning groove 15. The motor 16 drives the cutting blade 17 to rotate, and the cutting frame 5 descends to perform pipe cutting. A positioning mechanism is provided on the top of the base 1. The pipe material 23 is provided on the positioning mechanism. The positioning mechanism can position and fix the pipe material 23. The positioning mechanism can position the pipe material 23 directly below the cutting frame 5. The central axis of the rotating shaft 6 and the axis of the pipe material 23 are located on the same vertical center line.

[0034] The drive mechanism includes an inner groove 7 and an inner groove 8 disposed within the lifting frame 4. A worm gear 9 is fixedly connected to the outer surface of the rotating shaft 6 within the inner groove 7. A worm 10 is rotatably connected to the inner groove 8 and meshes with the worm gear 9. The contact position between the worm 10 and the inner wall of the inner groove 8 is positioned and installed by a bearing. The lifting frame 4 is provided with a mounting groove 11, and a motor 12 is disposed within the mounting groove 11, with its output end fixedly connected to one end of the worm 10. During operation, the motor 12 drives the worm 10 to rotate, the worm 10 drives the worm gear 9 to rotate, the worm gear 9 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the cutting... The cutting frame 5 rotates, which drives the cutting blade 17 to rotate at an angle. This controls the cutting angle of the pipe material 23 to meet the cutting work at different tilt angles. The motor 12 can be a stepper motor, which, together with the control equipment, controls the rotation angle of the cutting blade 17, such as 30°, 45°, 60°, etc. This can meet the pipe end cutting requirements at corresponding angles. The worm gear 9 and worm 10 have a self-locking effect, and the stepper motor also has a self-locking effect. This ensures the stability of the positioning of the cutting blade 17 after the angle is adjusted, thereby ensuring the stability of pipe cutting.

[0035] The positioning mechanism includes a fixed base 18 fixed to the top of the base 1, a clamping base 19 rotatably connected to the fixed base 18, and rotating parts 20 fixedly connected to both the fixed base 18 and the clamping base 19. The two rotating parts 20 are rotatably connected by a rotating shaft 21, which passes through the two rotating parts 20, ensuring that they can be stably connected together and can also rotate relative to each other. This allows the clamping base 19 to rotate open or close normally. A clamping recess 22 is provided at the junction of the fixed base 18 and the clamping base 19. The pipe material 23 is located in the clamping recess 22. The clamping recess 22 is arc-shaped, which allows the pipe to be stably placed into it.

The two sets of structures can stably position the pipe material 23. The pressing mechanism can be used to position pipe materials 23 of different diameters.

[0036] Cover frame 14 is fixedly mounted on cutting frame 5 with bolts, as shown in the attached figure. Figure 2 As shown, the cover frame 14 is provided with a through hole, and a bolt is inserted into the through hole. The inner wall of the mounting recess 13 on the cutting frame 5 is provided with a corresponding threaded hole. By screwing the bolt into the threaded hole, the cover frame 14 can be installed on the cutting frame 5. This can provide a shielding and protection effect for the cutting blade 17, and it can also be disassembled and opened normally, which is convenient for regular maintenance or replacement of the blade.

[0037] The clamping mechanism includes a receiving groove 24 located at the top of the clamping recess 22 on the clamping seat 19. A clamping block 25 is slidably connected within the receiving groove 24. An adjusting screw 26 is rotatably connected to the top of the clamping block 25. The engagement position of the adjusting screw 26 and the clamping block 25 is positioned and installed via a bearing. A threaded groove 27 is provided at the top of the receiving groove 24. The adjusting screw 26 is threadedly connected to the threaded groove 27. The adjusting screw 26 and the threaded groove 27 can adopt a Spiral self-locking thread type. The root of the thread has a unique 30° wedge-shaped slope, so that the normal force generated by the thread contact surface forms a 60° angle with the bolt axis. This provides a self-locking effect during use, ensuring anti-loosening performance. This ensures that loosening and slippage will not occur during use. This ensures that after the clamping block 25 is adjusted by raising and lowering, it can be stably clamped to the pipe surface, preventing loosening due to cutting vibration, and ensuring the stability of the pipe positioning. (See attached...) Figure 4 As shown, a rotating wheel is provided on the top of the adjusting screw 26, which facilitates the rotation adjustment of the adjusting screw 26. The clamping block 25 and the storage groove 24 are nested and slidingly fitted, which can limit and guide the lifting and lowering of the clamping block 25, so that it can slide and rise and fall smoothly.

[0038] One end of the clamping seat 19 is rotatably connected to an arc-shaped buckle pin 28, and a fixed post is fixedly connected to the surface of the clamping seat 19. One end of the buckle pin 28 is nested and rotated on the outer surface of the fixed post, so that it can be rotated normally for opening or closing operations. One end of the fixed seat 18 is fixedly connected to a buckle ring 29. The buckle pin 28 and the buckle ring 29 are set to be fastened together. This structure can not only make the clamping seat 19 stably docked and fixed together with the fixed seat 18, but also can be easily disassembled and opened, ensuring the flexibility of the structure in use.

[0039] The frame 2 is equipped with a controller 30. The electric push rod 3, motor 12, motor 216 are all electrically connected to the controller 30. The controller 30 can be a GD32 microcontroller, which can stably control the operation of each component.

[0040] Working principle: When using the pipe cutting device, the positioning mechanism can position and fix the pipe material 23, and the clamping mechanism can clamp the pipe material 23. The drive mechanism drives the rotating shaft 6 to rotate, the rotating shaft 6 drives the cutting frame 5 to rotate, and the cutting frame 5 drives the cutting blade 17 to rotate. After adjusting the cutting angle, the motor 16 is started. The motor 16 drives the cutting blade 17 to rotate. The electric push rod 3 is started. The electric push rod 3 drives the lifting frame 4 to descend. The lifting frame 4 drives the cutting frame 5 to descend, and the cutting frame 5 drives the cutting blade 17 to descend to cut the pipe material 23.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
