An installation mechanism is arranged on the mounting seat 4, and an installation plate 6 is fixedly connected to the opposite two side surfaces of the laser cutting head 2, and a clamping groove 7 corresponding to the installation mechanism is arranged in the side wall of the installation plate 6.

[0024] The interval adjustment mechanism includes a stepping motor 8, a rotating rod 9, a first bevel gear 10, a bidirectional screw rod 11, a second bevel gear 12, a nut block 13, a connecting rod 14 and a sliding hole 15.

[0025] The stepping motor 8 is vertically fixed to the outer side of the long axis direction of the frame shell 1, the main shaft end of the stepping motor 8 penetrates into the frame shell 1 and is fixedly connected with the rotating rod 9, the rotating rod 9 is fixedly connected with two symmetrically arranged first bevel gears 10, one bidirectional screw rod 11 is arranged on the inner side of each of the two side edges of the long axis direction of the frame shell 1, and the two bidirectional screw rods 11 are symmetrically arranged in the frame shell 1 along the long axis direction; the direction of the bidirectional screw rod 11 is perpendicular to the direction of the rotating rod 9, the second bevel gear 12 is fixedly connected to one end of each of the two bidirectional screw rods 11 near the rotating rod 9, and each second bevel gear 12 is meshed with one first bevel gear 10; two groups of symmetrically arranged nut blocks 13 are threadedly connected to the two bidirectional screw rods 11, one group of connecting rods 14 is fixedly connected to the opposite side of each group of nut blocks 13, and the sliding hole 15 is arranged in the inner side of each of the two side walls of the long axis direction of the frame shell 1, and each group of connecting rods 14 penetrates through the two sliding holes 15 and is fixedly connected with one mounting seat 4.

[0026] When the interval of the two laser cutting heads 2 needs to be adjusted during the laser engraving and cutting process, the stepping motor 8 is started to work, and the rotating rod 9 rotates accordingly. Since each first bevel gear 10 is meshed with a second bevel gear 12, the two bidirectional lead screws 11 rotate simultaneously. Since the bidirectional lead screws 11 are threadedly connected with the two groups of nut blocks 13, at this time, the two groups of nut blocks 13 are displaced in opposite directions, thereby driving the two laser cutting heads 2 to be displaced in opposite directions to achieve interval adjustment. The interval adjustment of the present embodiment is convenient, accurate and stable, and can be adjusted during the laser engraving and cutting process, thereby improving work efficiency.

[0027] As shown in Figure 4 and Figure 5 , the mounting mechanism includes a cover 16, a hand wheel rod 17, a double-head cam 18, a swing rod 19, a sliding block 20, a U-shaped clamping rod 21, and a return spring 22.

[0028] The cover 16 is fixed to the outer side of the mounting seat 4. The outer side wall of the cover 16 is inserted and rotationally connected with the hand wheel rod 17. The inner end of the hand wheel rod 17 is fixedly connected with the double-head cam 18. The two ends of the double-head cam 18 are hingedly connected with two parallel swing rods 19. The inner wall of the cover 16 is slidingly connected with two symmetrically arranged sliding blocks 20. Each sliding block 20 is hingedly connected with a swing rod 19. The far side of each sliding block 20 is fixedly connected with a U-shaped clamping rod 21. The two U-shaped clamping rods 21 are oppositely arranged. Each U-shaped clamping rod 21 extends above the side of the mounting seat 4. The return spring 22 is fixedly connected between the sliding block 20 and the inner wall of the cover 16.

[0029] When the laser cutting head 2 needs to be disassembled, the hand wheel rod 17 is rotated, the rotating hand wheel rod 17 drives the double-head cam 18 to rotate, the two swing rods 19 are displaced and swing, thereby pushing the two sliding blocks 20 to move away. At this time, the two return springs 22 are squeezed and contracted to generate elastic force until the U-shaped clamping rod 21 is separated from the clamping groove 7 on the mounting plate 6. At this time, the displacement of the laser cutting head 2 is no longer limited, and the laser cutting head 2 can be removed from the mounting seat 4. The installation and disassembly are convenient, the laser cutting head 2 is easy to maintain, and the work efficiency is improved.

[0030] As shown in Figure 4 , the upper side wall of the mounting seat 4 is fixedly connected with two symmetrically arranged side baffles 23. Each U-shaped clamping rod 21 penetrates through a side baffle 23 to improve the limiting and fixing effect of the laser cutting head 2.

[0031] As shown in Figure 4 , the two ends of the cover 16 are provided with through holes, and the two U-shaped clamping rods 21 pass through the two through holes to facilitate the displacement of the U-shaped clamping rod 21.

[0032] As shown in Figure 3As shown: the inner wall of both sides of sliding port 15 and the two side walls of connecting rod 14 are frictionally connected, so that the nut block 13 fixed with the connecting rod 14 keeps linear displacement.

[0033] As shown: Figure 3 As shown: the inner wall of frame shell 1 is rotationally connected with the end of rotating rod 9 through bearing seat, so that the rotating rod 9 rotates more stably.

[0034] The working principle of the embodiment is: in the process of laser engraving and cutting, when the interval of the two laser cutting heads 2 needs to be adjusted, the step motor 8 is started to work, and the motor 8 in working state drives the rotating rod 9 to rotate, since each first bevel gear 10 is meshed with a second bevel gear 12, and then the two bidirectional lead screws 11 rotate simultaneously; since the bidirectional lead screws 11 are threadedly connected with the two groups of nut blocks 13, at this time, the two groups of nut blocks 13 are reversely displaced, and then drive the two laser cutting heads 2 to reversely displace to realize interval adjustment, so that the interval adjustment is convenient, accurate and stable;

[0035] When the laser cutting head 2 needs to be disassembled, only the hand wheel rod 17 is rotated, the rotating hand wheel rod 17 drives the double-headed cam 18 to rotate, the two swing rods 19 swing and displace, and then push the two sliding blocks 20 to displace away, at this time, the two return springs 22 are extruded and contracted and generate elastic force, the elastic force pushes the U-shaped clamping rod 21 to separate from the clamping groove 7 on the mounting plate 6, at this time, the displacement of the laser cutting head 2 is limited, that is, the laser cutting head 2 can be taken off from the mounting seat 4, the installation and disassembly are convenient, so that the laser cutting head 2 is convenient to overhaul.

[0036] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
