[0026] 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.

[0027] Embodiment

[0028] As Figure 1 and Figure 3 shown, a laser cutting machine for special-shaped steel with a lifting cutting table includes: a mounting mechanism 1, a recycling mechanism 2, and a positioning mechanism 3. The recycling mechanism 2 includes a rectangular table 21. A plurality of arched plates 23 are fixedly connected to the inner wall of the rectangular table 21. The protrusions of the arched plates 23 face upward, facilitating the falling of waste materials. Above the arched plates 23, there is a clamping mechanism 5 for fixing the special-shaped steel and a lifting mechanism 4 for lifting the clamping mechanism 5. And a recycling box 24 for collecting waste materials is arranged inside the rectangular table 21; the positioning mechanism 3 is used to limit the position of the recycling box 24.

[0029] The waste materials generated by the laser cutting of the laser cutting machine will first hit the arched plates 23. Since the protrusions of the arched plates 23 face upward, the waste materials can easily fall into the recycling box 24.

[0030] As Figure 4 shown, the positioning mechanism 3 includes a bearing seat 31. The bearing seat 31 is fixed on the outer wall of the rectangular table 21. A connecting shaft 32 is rotatably sleeved in the inner ring of the bearing seat 31. Both ends of the connecting shaft 32 are fixedly connected with a positioning plate 33 and a gear 34 respectively. The positioning plate 33 is in contact with the outer wall of the recycling box 24.

[0031] Specifically, rotating the connecting shaft 32 can drive the positioning plate 33 to rotate synchronously. When the positioning plate 33 is separated from the recycling box 24, the recycling box 24 can be taken out of or put into the rectangular table 21. When the positioning plate 33 rotates below the rectangular table 21 and is in contact with the recycling box 24, the recycling box 24 will be placed inside the rectangular table 21 and cannot be taken out.

[0032] As Figure 4 shown, a guide groove is opened on the outer wall of the rectangular table 21. A rack 35 is slidably connected to the guide groove. Due to the limitation of the guide groove, the rack 35 can only move linearly up and down. The rack 35 meshes with the gear 34 to limit the rotation of the connecting shaft 32. And a spring 36 is fixedly connected to one side of the rack 35. The end of the spring 36 away from the rack 35 is fixedly connected to the guide groove.

[0033] Specifically, when the gear 34 meshes with the rack 35, the connecting shaft 32 cannot rotate. If you want to rotate the connecting shaft 32, you need to lift the rack 35 upward until it disengages from the gear 34. At this time, the connecting shaft 32 can rotate. When the rack 35 is released, the acting force of the spring 36 will push the rack 35 back to its original position and keep meshing with the gear 34 all the time without external interference.

[0034] As Figure 2 shown, there are four sets of lifting mechanisms 4, which are respectively in pairs. The lifting mechanism 4 includes a lifting frame 41, the lifting frame 41 is fixed on the side wall of the square table 21, and a connecting block 42 is slidably connected to the inner wall of the lifting frame 41. The connecting block 42 is in the shape of "I", so that it can only move up and down on the inner wall of the lifting frame 41, and a first lead screw 43 is rotatably connected. One end of the first lead screw 43 penetrates through one side of the lifting frame 41 and is threadedly connected to the connecting block 42.

[0035] Specifically, by rotating the first lead screw 43, through the threaded fit with the connecting block 42 and the sliding fit with the inner wall of the lifting frame 41, it can move up and down, and the lifting of the connecting block 42 can drive the clamping mechanism 5 to lift together.

[0036] As Figure 1 shown, the clamping mechanism 5 includes two slide bars 51. The two ends of the slide bar 51 are respectively fixedly connected to the two connecting blocks 42, and a clamping frame 52 is slidably connected to the slide bar 51. The clamping frame 52 is threadedly connected with a positioning bolt to fix the position of the clamping frame 52 on the slide bar 51 through the positioning bolt. A second lead screw 53 is threadedly connected to the side of the clamping frame 52 away from the square table 21. One end of the second lead screw 53 close to the square table 21 is rotatably connected to a clamping plate 54. One side of the clamping plate 54 is fixedly connected to a guide rod 55, and the guide rod 55 movably penetrates through the side wall of the clamping frame 52.

[0037] Specifically, by pushing the clamping frame 52, it can slide on the slide bar 51. When the position of the clamping frame 52 is adjusted, it is positioned through the positioning bolt. By rotating the second lead screw 53, through the threaded fit with the clamping frame 52, it moves on the side wall of the clamping frame 52. The clamping plate 54, through the cooperation of the guide rod 55 and the clamping frame 52, does not rotate together with the second lead screw 53, but moves up and down together, so as to facilitate the clamping and fixing of special-shaped steel.

[0038] As Figure 1As shown in the figure, the installation mechanism 1 includes a base 11. The top of the base 11 is fixedly connected with a top plate 13 through a support rod 12. The laser cutting machine is fixed on the top plate 13 through a cross slide. The laser cutting machine can be moved to the required position through the cross slide. At the same time, an oil cylinder is fixedly installed on one side of the base 11 close to the return table 21. The output end of the oil cylinder is fixedly connected with a side plate 22. The side plate 22 is movably sleeved on the outer circle of the support rod 12. The return table 21 can be driven to lift through the oil cylinder.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it.
