[0045] Specifically: The second mounting base 23 has a mounting hole, and the output end of the cutting motor 24 is connected and fixed to the cutting disk 25 through a rotating shaft, which is rotatably installed in the mounting hole.

[0046] In actual operation: The steel pipe is placed on two rotating rollers 17. The second drive component 18 is activated to drive one of the rotating rollers 17 to rotate. The rotating roller 17 drives the steel pipe to rotate. The third drive component 22 is activated to drive the support plate 20 to move downward along the gantry 6.

The first mounting seat 14 drives the two rotating rollers 17 to move, thereby adjusting the distance between the two rotating rollers 17. This is suitable for pipes of different diameters.

[0054] Example 3

[0055] Based on Embodiment 1 or Embodiment 2, a second sliding groove 4 and a second screw hole 5 are provided on the workbench 1. A second sliding block 32 is slidably installed in the second sliding groove 4 of the workbench 1. An adjusting bolt 33 is rotatably installed on the second sliding block 32.

The second sliding block 32 drives the support rod and positioning mechanism 36 to move. The distance between the positioning plate 3607 and the cutting disc 25 is equal to the length of the steel pipe to be cut. When the end of the steel pipe contacts the positioning plate 3607, the movement of the steel pipe is paused, and the fourth driving component 35 is activated to drive the positioning plate 3607 away from the steel pipe. After the cutting is completed, the fourth driving component 35 is activated to drive the positioning plate 3607 to reset, realizing the function of repeated positioning.

[0059] Example 4

[0060] Based on Example 3, such as Figures 10-12 As shown, the positioning mechanism 36 includes a second sliding cavity 3601 fixedly installed on the power end of the fourth driving component 35. A first detection contact 3602 is detachably installed in the second sliding cavity 3601. A second sliding plate 3603 is slidably installed in the second sliding cavity 3601.

[0062] In actual operation: the end of the steel pipe contacts the positioning plate 3607 and pushes the positioning plate 3607 to move. The positioning plate 3607 drives the detection rod 3605 to move. The detection rod 3605 pushes the second sliding plate 3603 to move along the second sliding cavity 3601. The second sliding plate 3603 drives the second detection contact 3604 to contact the first detection contact 3602 and compresses the second elastic component 3606. At this time, the distance between the positioning plate 3607 and the cutting disc 25 is equal to the length of the steel pipe to be cut, realizing the automatic positioning function. The fourth driving component 35 is activated to drive the positioning mechanism 36 away from the end of the pipe, realizing the automatic positioning function.

[0063] The working principle of this utility model is as follows: A steel pipe is placed on two rotating rollers 17. The second driving component 18 is activated to drive one of the rotating rollers 17 to rotate. The rotating roller 17 drives the steel pipe to rotate. The third driving component 22 is activated to drive the support plate 20 to move downward along the gantry frame 6. The support plate 20 drives the guide rod 21 to move along the guide hole 8. At the same time, the support plate 20 drives the cutting mechanism to move downward. The support plate 20 drives the lower pressure roller 31 to contact the upper end face of the steel pipe. As the support plate 20 continues to move downward, the lower pressure roller 31 drives the sliding frame 30 to move along the first sliding opening 27 and drives the first sliding plate 28 to move along the first sliding cavity 26, compressing the first elastic component 29. The lower pressure roller 31 exerts downward pressure on the steel pipe. In conjunction with the two rotating rollers 17, it prevents the steel pipe from moving during rotation, thereby affecting the cutting quality. The cutting mechanism cuts the pipe, improving the cutting quality and efficiency.
