[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0019] Figure 1 Shows the overall structural schematic diagram of the laser cutting device for bevel cutting of pipes; Figure 2 Shows the back structural schematic diagram of the laser cutting device for bevel cutting of pipes; Figure 1In the laser cutting device for bevel cutting of pipe materials, which is used to cut the pipe fitting 300, it includes a base plate 100 and a laser cutting assembly 200 installed at one end of the base plate 100. A fixed cylinder 110 is rotatably connected to the base plate 100. An axial hole for the pipe fitting 300 to penetrate is provided in the fixed cylinder 110 along the axial direction. The output end of the laser cutting assembly 200 faces the axial hole. Two clamping parts 120 are oppositely arranged on one end face of the fixed cylinder 110; the two oppositely arranged clamping parts 120 can clamp and fix the pipe fitting 300 to limit the position of the pipe fitting 300 and can limit the pipe fitting 300 in the plane where the axis is located; two opposite clamping parts 120 are provided at both ends of the fixed cylinder 110, and in the vertical projection plane, the four clamping parts 120 are evenly distributed around the axial hole; that is to say, the four clamping parts 120 will clamp and center the pipe fitting 300 from four directions, so that the pipe fitting 300 is placed at the central axis position of the base plate 100, which is beneficial to cooperate with the action of the laser cutting assembly 200. And the four clamping parts 120 are distributed in two opposite pairs on the two end faces of the fixed cylinder 110, that is to say, the pipe fitting 300 can be restricted at two spaced positions, increasing the effect after the pipe fitting 300 is locked; and the laser cutting assembly 200 is composed of a hydraulic push rod and a laser cutting head installed at the output end of the hydraulic push rod. In specific use, the hydraulic push rod can be started to drive the laser cutting head to move in the output direction, which is well known to those skilled in the art and should not be construed as a limitation to this application; a toothed ring 130 is coaxially connected to the outside of the fixed cylinder 110, and an output motor two 150 is installed on the end face of the base plate 100. The output end of the output motor two 150 penetrates the base plate 100 and is connected with a gear 140. The gear 140 meshes with the toothed ring 130; when the output motor two 150 is started, the output end of the output motor two 150 can drive the gear 140 to rotate, and the gear 140 meshes with the toothed ring 130, which can drive the toothed ring 130, the fixed cylinder 110 and the clamped pipe fitting 300 to rotate, so as to cooperate with the laser cutting assembly 200 to realize the circumferential cutting of the pipe fitting 300.

[0020] It should be noted that in this embodiment, as Figure 1 shown, the pipe fitting 300 is a circular pipe with a circular cross-section. In some other embodiments, the cross-section of the pipe fitting 300 can also be some other regular or irregular polygons. The circle should not be construed as a limitation to this application.

[0021] Figure 3 The structural schematic diagram of the clamping part 120 is shown; Figure 3Among them, the clamping part 120 includes a hydraulic push rod 121 connected to the end face of the fixed cylinder 110, a "U"-shaped frame 122 installed at the output end of the hydraulic push rod 121, and a roller 123 rotatably arranged at the open end of the "U"-shaped frame 122; when the hydraulic push rod 121 is started, the output end of the hydraulic push rod 121 can drive the "U"-shaped frame 122 and the roller 123 to move towards the axis, that is, the two relatively arranged rollers 123 move towards each other, and the two will clamp the pipe fitting 300 in the middle. And because the roller 123 is rotatably arranged at the open end of the "U"-shaped frame 122, therefore, by applying an axial driving force to the pipe fitting 300, the pipe fitting 300 can be forced to move axially. While the roller 123 rotates, it can offset the axial movement of the pipe fitting 300 and still maintain the fixing effect on the pipe fitting 300; an output motor one 124 is installed on the "U"-shaped frame 122, and the output end of the output motor one 124 is coaxially installed at one end of the roller 123; when the output motor one 124 is started, the roller 123 can be driven to rotate around its axis, so as to actively drive the pipe fitting 300 to move axially; in actual use, after the pipe fitting 300 passes through the shaft hole, start the four hydraulic push rods 121, and the four rollers 123 can be driven to approach the center of the shaft hole to center the pipe fitting 300, and then start the output motor two 150 to drive the pipe fitting 300 to rotate and cooperate with the telescopic movement of the laser cutting assembly 200 to realize circumferential cutting. At the same time, only need to start the output motor one 124 to drive the pipe fitting 300 to move axially to realize the bevel cutting of the pipe fitting 300.

[0022] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
