DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-6 In an embodiment of the present invention, a pipe cutting machine for pipe processing includes a laser cutting knife 13, and a slide 12 is sleeved on the outer side of the laser cutting knife 13; a connecting member 11 is provided on the side of the slide 12 away from the laser cutting knife 13, and two slide rods are symmetrically welded on the connecting member 11, and the two sides of the slide 12 are respectively slidably connected to the two slide rods; a hydraulic pump 10 is welded above the connecting member 11, and the telescopic rod of the hydraulic pump 10 extends to the inner side of the connecting member 11, and the telescopic rod of the hydraulic pump 10 is fixedly connected to the slide 12;

[0028] The side of the connecting member 11 away from the sliding member 12 is welded to the bracket 8, and a three-jaw chuck 1 is provided in the middle of the bracket 8; a transmission shaft 2 is sleeved in the middle of the side of the three-jaw chuck 1 away from the laser cutting knife 13, and a motor 3 is fixedly connected to the end of the transmission shaft 2 away from the three-jaw chuck 1; a U-shaped frame 4 is sleeved on the outer side of the transmission shaft 2, and the U-shaped frame 4 is located between the three-jaw chuck 1 and the motor 3;

[0029] Two connecting plates 18 are symmetrically provided on one side of the turntable 16 away from the three-jaw chuck 1, and the two connecting plates 18 are respectively located on both sides of the rectangular opening of the turntable 16; one adjacent side of the two connecting plates 18 is rotatably connected to a fixed wheel 20; the two ends of the same side of the two connecting plates 18 are rotatably connected by a rotating member 17 respectively.

[0030] By adopting the above technical solution, when in use, the pipe to be cut is passed through the rectangular opening in the middle of the turntable 16, and one end of the pipe is clamped and fixed by the three-jaw chuck 1. After the three-jaw chuck 1 fixes one end of the pipe, the distance between the two connecting plates 18 is adjusted by two rotating parts 17, so that the two fixed wheels 20 can support and fix the pipe. After the pipe is fixed, the distance between the laser cutting knife 13 and the pipe is adjusted by the hydraulic pump 10 according to the diameter of the pipe, so that the laser cutting knife 13 can cut the pipe normally. After adjusting the position of the laser cutting knife 13, the pipe cutting work can be carried out. When cutting the pipe, the motor 3 controls the three-jaw chuck 1 to drive the pipe to rotate, so that the laser cutting knife 13 can cut the pipe completely. Compared with traditional metal tools, the laser cutting knife 13 has a faster cutting speed and the amount of debris generated during the cutting process is also very small. After cutting, the cut surface of the pipe is relatively smooth as a whole, and no burrs are generated, so that subsequent processing work can be carried out normally.

[0031] In this embodiment, a sleeve 7 is welded on the top of the U-shaped frame 4, and a threaded hole is provided in the middle of the sleeve 7; a screw rod 5 is threadedly connected to the inner side of the threaded hole of the sleeve 7;

[0032] One end of the screw rod 5 is rotatably connected to the bracket 8, and the other end of the screw rod 5 is fixedly connected to a motor 2 6.

[0033] By adopting the above technical solution, according to the length of the pipeline and the requirements for pipeline cutting, the motor 2 6 drives the screw rod 5 to rotate, so as to adjust the distance between the three-jaw chuck 1 and the turntable 16. The above components greatly increase the maneuverability of the pipeline cutting device, thereby increasing the scope of application of the pipeline cutting device.

[0034] In this embodiment, a rotating disk 16 is provided below the connecting member 11; a rectangular hole is provided in the middle of the rotating disk 16 for the pipeline to pass through, and a fixing member 14 is provided on both sides of the rotating disk 16; the two fixing members 14 are welded to the bracket 8;

[0035] Both ends of the two fixing members 14 are rotatably connected to an auxiliary wheel 15 ; the four auxiliary wheels 15 are respectively located at the four corners of the turntable 16 , and the four turntables 16 are all in contact with each other.

[0036] By adopting the above technical solution, when the two fixed wheels 20 fix the pipeline and the three-jaw chuck 1 controls the pipeline to rotate, the turntable 16 will rotate synchronously with the pipeline, and the four auxiliary wheels 15 can make the rotation of the turntable 16 smoother, thereby reducing the working pressure of the motor 3 and effectively extending the service life of the motor 3.

[0037] The working principle of the present invention is as follows: when in use, the pipe to be cut is passed through the rectangular opening in the middle of the turntable 16, and one end of the pipe is clamped and fixed by the three-jaw chuck 1. After the three-jaw chuck 1 fixes one end of the pipe, the distance between the two connecting plates 18 is adjusted by two rotating parts 17, so that the two fixed wheels 20 can support and fix the pipe. After the pipe is fixed, the distance between the laser cutting knife 13 and the pipe is adjusted by the hydraulic pump 10 according to the diameter of the pipe, so that the laser cutting knife 13 can cut the pipe normally. After adjusting the position of the laser cutting knife 13, the pipe cutting work can be carried out. When cutting the pipe, the motor 3 controls the three-jaw chuck 1 to drive the pipe to rotate, so that the laser cutting knife 13 can completely cut the pipe. Compared with traditional metal knives, the cutting speed of the laser cutting knife 13 is faster, and the amount of debris generated during the cutting process is also very small. After cutting, the cut surface of the pipe is relatively smooth as a whole, and no burrs are generated, so that subsequent processing work can be carried out normally.

[0038] As a further optimization, according to the length of the pipeline and the demand for pipeline cutting, the distance between the three-jaw chuck 1 and the turntable 16 can be adjusted by driving the screw rod 5 to rotate through the motor 2 6. The above components greatly increase the maneuverability of the pipeline cutting device, thereby increasing the scope of application of the pipeline cutting device;

[0039] When the two fixed wheels 20 fix the pipe and the three-jaw chuck 1 controls the pipe to rotate, the turntable 16 will rotate synchronously with the pipe, and the four auxiliary wheels 15 can make the turntable 16 rotate more smoothly, thereby reducing the working pressure of the motor 3 and effectively extending the service life of the motor 3.
