In order to realize the cutting action of the steel pipe, the motor drives the cutter disc to rotate at high speed through the third transmission group 603, further, the cutting assembly 5 comprises a cutting motor 501, the cutting motor 501 is fixedly installed in the machine shell 405, the third transmission group 603 is arranged on one side of the machine shell 405, the large pulley 6011 of the third transmission group 603 is fixedly connected to the output end of the cutting motor 501, and the cutting disc 502 is rotatably installed on the other side of the machine shell 405. The cutting disc 502 is fixedly connected with the small pulley of the third transmission group 603 through the machine shell 405 on one side.

[0028] The transmission assembly 6 of the cutting device is composed of four transmission groups with the same structure, including the first transmission group 601, the second transmission group 602, the third transmission group 603 and the fourth transmission group 604, the first transmission group 601, the second transmission group 602, the third transmission group 603 and the fourth transmission group 604 comprise a large pulley 6011 and a small pulley 6013 connected through a transmission belt 6012.

Specifically, the machine shell 405 is fixedly installed at one end away from the support plate 402 of the telescopic plate 404. Through the pushing of the telescopic plate 404, the machine shell 405 can be telescoped along the direction of the support plate 402, so as to adjust the position of the cutting disc 502 and adapt to the different cutting requirements of the steel pipe.

[0030] The cutting motor 501 in the cutting assembly 5 is fixedly installed inside the casing 405 and is responsible for providing power for the cutting disc 502. The output end of the cutting motor 501 is connected with the large belt pulley 6011 of the third transmission group 603 through a transmission shaft. When the cutting motor 501 operates, the large belt pulley 6011 is driven to rotate, and the third transmission group 603 can transmit and adjust the rotating speed of the cutting motor 501 to the cutting disc 502 through the transmission belt 6012 between the large belt pulley 6011 and the small belt pulley 6013, so as to realize the required cutting rotating speed. The cutting disc 502 rotates at high speed and acts on the surface of the steel pipe. The casing 405 is adjusted in position by the supporting plate 402, so that the cutting disc 502 can realize accurate cutting path on the surface of the steel pipe.

[0031] In order to realize the multifunctional driving of the motor, not only the power is applied to the cutting disc 502, but also the power is output through the other end of the driving shaft. The fourth transmission group 604 realizes the speed reduction effect on the rotating speed of the motor driving shaft. Further, the one end of the motor driving shaft away from the large belt pulley 6011 of the third transmission group 603 is fixedly connected with the first helical gear 503. The first helical gear 503 is meshingly connected with the second helical gear 504. The second helical gear 504 is rotatably installed on one side of the casing 405. The second helical gear 504 is fixedly connected with the small belt pulley 6013 of the fourth transmission group 604. The large belt pulley 6011 of the fourth transmission group 604 is rotatably installed on one side of the casing 405. In order to realize the speed reduction driving of the screw rod 406 while cutting the steel pipe, the cutting disc 502 is driven to displace along the direction of the screw rod 406 under the cooperation of the screw pipe 407, so as to realize the change of the cutting depth. Further, the large belt pulley 6011 of the fourth transmission group 604 is fixedly connected with the screw rod 406 rotatably installed on one side of the casing 405. The screw pipe 407 is externally screwed with the screw rod 406. The screw pipe 407 is fixed on one side of the supporting plate 402.

[0032] The one end of the driving shaft of the motor is fixedly connected with the large belt pulley 6011 of the third transmission group 603, which is used for transmitting power to drive the cutting disc 502. The other end of the driving shaft of the motor is fixedly connected with the first helical gear 503, which realizes the further output of the power. The first helical gear 503 on the driving shaft is meshingly connected with the second helical gear 504. The second helical gear 504 can transmit the rotating power of the driving shaft to the outside of the casing 405, which provides support for the next power transmission. The one end of the second helical gear 504 is fixedly connected with the small belt pulley 6013 of the fourth transmission group 604, which transmits the power of the helical gear to the fourth transmission group 604, and further realizes the multidirectional power output.

[0033] The small pulley 6013 of the fourth transmission group 604 is connected with the large pulley 6011 through the transmission belt 6012. Since the radius of the large pulley 6011 is larger than that of the small pulley 6013, the transmission ratio will cause the rotation speed to slow down, thereby achieving deceleration. The large pulley 6011 of the fourth transmission group 604 is coaxially installed with the lead screw 406, so that the rotation of the large pulley 6011 directly drives the lead screw 406 to rotate. The lead screw 406 is externally screwed with a screw pipe 407, and the screw pipe 407 is fixed on one side of the support plate 402. When the lead screw 406 rotates, the screw pipe 407 will move axially along the lead screw 406 due to the screw transmission relationship. This axial displacement transmission enables the support plate 402 and the cutting disc 502 to move in the direction of the lead screw 406, thereby changing the cutting depth of the cutting disc 502 relative to the steel pipe.

[0034] In summary, when the motor operates, not only does it drive the cutting disc 502 to rotate at high speed for ring cutting, but also it drives the lead screw 406 to move the screw pipe 407 axially along the lead screw 406 through the fourth transmission group 604. By adjusting the rotation speed of the motor, the displacement amount of the cutting disc 502 can be controlled, thereby accurately adjusting the cutting depth and achieving multi-level cutting of the steel pipe.

[0035] In order to drive the slide rod 408 to rotate synchronously while driving the lead screw 406, and without affecting the movement of the shell 405, the slide rod 408 is driven to move around the gear 403 twice through the first transmission group 601 and the second transmission group 602, and is engaged with the tooth ring 401, thereby driving the cutting knife to move in a ring shape along the tooth ring 401, realizing integrated ring movement, cutting and steel pipe thickness cutting position. Further, the slide rod 408 is slidably installed in the lead screw 406. One end of the slide rod 408 penetrates through the support plate 402 and is fixedly connected with the large pulley 6011 of the first transmission group 601. The small pulley 6013 of the first transmission group 601 is rotatably installed on one side of the shell 405. One side of the small pulley 6013 of the first transmission group 601 is fixedly connected with the large pulley 6011 of the second transmission group 602. The small pulley 6013 of the second transmission group 602 is rotatably installed on one side of the support plate 402, and one side of the small pulley 6013 of the second transmission group 602 is fixedly connected with the ring gear 403.

[0036] The slide rod 408 is slidingly installed inside the lead screw 406 and is driven to move synchronously by the lead screw 406, ensuring that the cutting assembly 5 realizes linkage control of position and depth during cutting. One end of the slide rod 408 penetrates the support plate 402 and is fixedly connected to the large pulley 6011 of the first transmission group 601, realizing power transmission of synchronous rotation. The slide rod 408 drives the large pulley 6011 of the first transmission group 601 to rotate, and the large pulley 6011 of the first transmission group 601 drives the small pulley 6013 of the first transmission group 601 to accelerate, preliminarily increasing the rotation speed of the slide rod 408. The small pulley 6013 of the first transmission group 601 is installed on one side of the machine shell 405, and one end thereof is fixedly connected to the large pulley 6011 of the second transmission group 602, providing power for the next step of transmission. The small pulley 6013 of the first transmission group 601 is connected with the large pulley 6011 of the second transmission group 602, further transmitting the power of the slide rod 408 to the second transmission group 602. The small pulley 6013 of the second transmission group 602 is installed on the support plate 402 and is adjusted through the transmission ratio.

[0037] The other end of the small pulley 6013 of the second transmission group 602 is fixedly connected to the surrounding gear 403. When the small pulley 6013 rotates at high speed, the surrounding gear 403 is driven to move along the track of the tooth ring 401. The surrounding gear 403 is engaged with the tooth ring 401 fixed on the base plate 1, thereby pushing the cutting assembly 5 to move along the track of the tooth ring 401, ensuring that the cutting disc 502 uniformly surrounds the steel pipe for cutting.

[0038] While the lead screw 406 drives the cutting disc 502 to adjust the depth, the slide rod 408 drives the surrounding gear 403 through the first transmission group 601 and the second transmission group 602, so that the cutting disc 502 moves along the track of the tooth ring 401, enabling the cutting device to realize synchronous adjustment of cutting depth and surrounding cutting path in the same structure, and meeting the accurate cutting requirements of steel pipes with different thicknesses.
