Three-dimensional laser pipe cutting technology, as an important branch of laser cutting technology, can realize accurate cutting of complex spatial curve pipes and plays an important role in the fields of automobile manufacturing, aerospace, engineering machinery and the like. Traditional three-dimensional laser pipe cutting devices usually adopt fixed clamping mechanisms to fix pipes and realize pipe cutting through the movement of laser cutting heads. However, this fixed mode has the following limitations: after the pipe is fixed, the pipe cannot be driven to move left and right, which limits the flexibility of the cutting path. SUMMARY

[0018] like Figures 1-2 As shown, this example can drive the pipe to move freely left and right, making it convenient to cut different positions on the pipe.

[0019] The three-dimensional laser tube cutting device includes a connector 9, with track rods 16 welded to both sides of the connector 9. The two track rods 16 are perpendicular to each other, and each track rod 16 has a rotating roller 17 at both ends. A total of four rotating rollers 17 are set on the two track rods 16, two horizontally and two vertically. The tube to be cut is inserted between the four rotating rollers 17, and the tube is supported by the four rotating rollers 17. At this time, the tube is set horizontally, and the tube can be moved freely left and right by rotating the four rotating rollers 17, which is convenient for cutting different positions on the tube.

[0020] like Figures 1-2 As shown, this example can achieve the effect of driving the pipe to move left and right by rotating four rollers 17.

[0021] Since each of the track rods 16 has two sliding blocks 14 slidably connected to it, and a motor 10 is connected to the sliding block 14 by screws, and the rotating roller 17 is connected to the output shaft of the corresponding motor 10, each sliding block 14 can slide on the corresponding track rod 16, thereby adjusting the distance between the two rotating rollers 17 on each track rod 16, so that the four rotating rollers 17 can support pipes of different sizes. The rotating rollers 17 can be driven to rotate by the motor 10, and the pipes can be moved left and right by the rotation of the four rotating rollers 17.

[0022] like Figures 1-2As shown in the figure, this example can achieve the effect of fixing the rotating roller 17 on the corresponding track bar 16.

[0023] Since the sliding seat 14 is connected with the fastening screw 13 through the thread, the fastening screw 13 is pressed on the track bar 16, and the sliding seat 14 can be fixed on the corresponding track bar 16 by rotating the fastening screw 13, thereby fixing the rotating roller 17 on the corresponding track bar 16.

[0024] As shown in the figure, Figures 1-2 As shown in the figure, this example can achieve the effect of fixing the two mutually perpendicular track bars 16 on the inner ring of the rotating ring 1.

[0025] Since the connecting piece 9 is welded on the inner ring of the rotating ring 1, the two mutually perpendicular track bars 16 are fixed on the inner ring of the rotating ring 1.

[0026] As shown in the figure, Figures 1-2 As shown in the figure, this example can achieve the effect of driving the pipeline to rotate around its own axis.

[0027] Since the rotating ring 1 is rotationally connected between the two arc-shaped sheets 4, each arc-shaped sheet 4 is connected with two stop blocks 6 through screws, the two stop blocks 6 on the arc-shaped sheet 4 are respectively blocked on the two sides of the rotating ring 1, the rotating ring 1 can rotate around its own axis between the two stop blocks 6, thereby driving the two track bars 16 and the four rotating rollers 17 to rotate around the axis of the rotating ring 1, and further driving the pipeline to rotate around its own axis, facilitating the ring cutting of the pipeline. The four rotating rollers 17 rotate to drive the pipeline to move freely left and right, cooperate with the pipeline to rotate around its own axis, thereby enabling the pipeline to move three-dimensionally to adjust the position, and cut the pipeline at different positions.

[0028] As shown in the figure, Figures 1-2 As shown in the figure, this example can achieve the effect of supporting the rotating ring 1 above the base 15.

[0029] Since the lower end of each arc-shaped sheet 4 is welded with a support bar 8, the two support bars 8 are connected with the base 15 through screws, and the base 15 and the two support bars 8 support the two arc-shaped sheets 4, thereby supporting the rotating ring 1 above the base 15.

[0030] As shown in the figure, Figures 1-2 As shown in the figure, this example can achieve the effect of driving the rotating ring 1 to rotate around its own axis.

[0031] Since the base 15 is connected with the motor two 12 through the screw, the output shaft of the motor two 12 is connected with the friction wheel 11 through the key, and the friction wheel 11 is in friction transmission with the outer side of the rotating ring 1, the friction wheel 11 is driven to rotate by the motor two 12, and then the rotating ring 1 is driven to rotate around its own axis by the friction wheel 11.

[0032] AsFigures 1-2 As shown, this example can achieve the effect of cutting around the pipe.

[0033] Due to the hollow seat 7 welded on the base 15, the upper part of the L-shaped frame 3 is connected with the laser generator 2 through screws, the hollow seat 7 is connected with the hydraulic cylinder 5 through screws, the upper end of the hydraulic cylinder 5 is connected on the L-shaped frame 3 through screws, the hollow seat 7 is vertically slidingly connected with the L-shaped frame 3, the L-shaped frame 3 can vertically slide on the hollow seat 7, the hydraulic cylinder 5 drives the L-shaped frame 3 to ascend and descend when it is extended and retracted, and then drives the laser generator 2 to move vertically, so that the laser generator 2 approaches the pipe, and then drives the pipe to rotate around the axis of the pipe, and then cuts around the pipe.
