Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and in particular to a transfer mechanism for a laser cutting machine. Background Technology

[0002] The transfer mechanism of a laser cutting machine is a device responsible for transferring the cut workpiece from the cutting area to other designated locations in the laser cutting production process, aiming to improve production automation and efficiency.

[0003] After traditional laser cutting, the workpiece transfer process often relies on manual operation. Manual transfer has several drawbacks. Firstly, the high temperature, intense light, and potentially harmful gases generated during laser cutting pose a potential threat to the operator's health. Secondly, manual operation is inefficient and easily affected by factors such as operator fatigue and mood, making it difficult to guarantee the stability and accuracy of the transfer, thus limiting the improvement of overall production efficiency. To address these issues, we propose a transfer mechanism for laser cutting machines. Utility Model Content

[0004] The main purpose of this utility model is to provide a transfer mechanism for a laser cutting machine, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A transfer mechanism for a laser cutting machine includes a base, an operating table on the inner side of the base, a laser head on the top of the operating table, two sets of first gears rotatably connected to the upper end of the base, the front ends of the first gears meshing with first racks via gears, the two sets of first racks being symmetrical to each other, two sets of symmetrical limiting blocks fixedly connected to the upper end of the base, a first slider slidably connected to the inner side of the limiting blocks, the rear end of the first slider being fixedly connected to the first rack, and clamping plates fixedly connected to opposite sides of the two sets of first racks.

[0007] Preferably, the upper end of the base is rotatably connected to two sets of first rotating blocks. The first rotating blocks are located behind the operating table. The upper end of the first rotating block is fixedly connected to a second gear. The outer side of the first rotating block is fixedly connected to a first connecting rod. The two sets of first connecting rods are symmetrical to each other. One end of the first connecting rod is fixedly connected to a second rotating block.

[0008] Preferably, a third rotating block is rotatably connected to the upper end of the second rotating block, a second connecting rod is fixedly connected to the outer side of the third rotating block, a fourth rotating block is fixedly connected to one end of the second connecting rod, and a third gear is fixedly connected to the upper end of the fourth rotating block.

[0009] Preferably, the rear end of one set of the two sets of third gears is engaged with a second rack via gear meshing, and the front end of the other set of the two sets of third gears is engaged with a third rack via gear meshing, with a first connecting plate fixedly connected between the second rack and the third rack.

[0010] Preferably, the rear end of one of the two sets of second gears is engaged with a fourth rack via gear meshing, and the front end of the other set of the two sets of second gears is engaged with a fifth rack via gear meshing, and a second connecting plate is fixedly connected between the fourth rack and the fifth rack.

[0011] Preferably, a first push block is fixedly connected to the upper end of the base, the front end of the first push block has an opening, the inner side of the first push block has a first groove, the inner side of the first groove is slidably connected to a second slider, the lower end of the second slider is fixedly connected to a second connecting plate, a cylinder is installed at the upper end of the first push block, and the output end of the cylinder is fixedly connected to the second slider.

[0012] Preferably, a second push block is movably connected to the front end of the first push block, a second groove is provided on the inner side of the second push block, a third slider is slidably connected to the inner side of the second groove, the lower end of the third slider is fixedly connected to the first connecting plate, the upper end of the third slider passes through the second groove and is fixedly connected to a sliding plate, and a sixth rack is fixedly connected to both sides of the second push block, the sixth rack meshing with the first gear.

[0013] Compared with the prior art, this utility model has the following beneficial effects: In use, the transfer mechanism of this laser cutting machine activates the cylinder, and the output end of the cylinder pushes the second slider and the second connecting plate to move. During the movement of the second connecting plate, the fourth rack meshes with one of the two sets of second gears, and the fifth rack meshes with the other set of second gears, causing both sets of second gears to rotate simultaneously and drive the first connecting rod to deflect. Then, through the rotational connection of the second and third rotating blocks, the second connecting rod deflects, thereby pushing the second push block forward. During this process, the sixth rack meshes with the first gear and rotates, causing the first gear to mesh with the first rack and remove the clamping plate from the operating table. Then, the second push block continues to move forward, pushing the cut workpiece off the surface of the operating table, reducing manual labor. When cutting the next workpiece, the cylinder outputs in the opposite direction, driving the second push block to move backward. During this backward movement, the sixth rack meshes with the first gear and rotates in the opposite direction, causing the clamping plate to move back onto the operating table and clamp the workpiece, preventing workpiece displacement and ensuring the accuracy and stability of laser cutting.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-5 As shown, a transfer mechanism for a laser cutting machine includes a base 1, an operating table 2 is provided on the inner side of the base 1, a laser head 3 is provided on the top of the operating table 2, two sets of first gears 4 are rotatably connected to the upper end of the base 1, the front end of the first gears 4 is meshed with a first rack 5 through gears, the two sets of first racks 5 are symmetrical to each other, two sets of mutually symmetrical limiting blocks 6 are fixedly connected to the upper end of the base 1, a first slider 7 is slidably connected to the inner side of the limiting block 6, the rear end of the first slider 7 is fixedly connected to the first rack 5, and a clamping plate 8 is fixedly connected to the opposite side of each of the two sets of first racks 5.

[0022] In this embodiment, two sets of first rotating blocks 9 are rotatably connected to the upper end of the base 1. The first rotating blocks 9 are located behind the operating table 2. The upper end of the first rotating blocks 9 is fixedly connected to a second gear 10. The outer side of the first rotating blocks 9 is fixedly connected to a first connecting rod 11. The two sets of first connecting rods 11 are symmetrical to each other. One end of the first connecting rod 11 is fixedly connected to a second rotating block 12.

[0023] Specifically, the rotation of the second gear 10 causes the first connecting rod 11 to deflect, which in turn causes the second rotating block 12 to rotate.

[0024] In this embodiment, the upper end of the second rotating block 12 is rotatably connected to the third rotating block 13, the outer side of the third rotating block 13 is fixedly connected to the second connecting rod 14, one end of the second connecting rod 14 is fixedly connected to the fourth rotating block 15, and the upper end of the fourth rotating block 15 is fixedly connected to the third gear 16.

[0025] Specifically, the second connecting rod 14 is deflected by the rotational connection between the second rotating block 12 and the third rotating block 13, which in turn causes the fourth rotating block 15 to drive the third gear 16 to rotate.

[0026] In this embodiment, the rear end of one set of the two sets of third gears 16 is engaged with the second rack 17 through gear meshing, and the front end of the other set of the two sets of third gears 16 is engaged with the third rack 18 through gear meshing. The second rack 17 and the third rack 18 are fixedly connected together by a first connecting plate 19.

[0027] Specifically, one set of the two sets of third gears 16 meshes with the second rack 17, and the other set of third gears 16 meshes with the third rack 18, causing the first connecting plate 19 to move to one side.

[0028] In this embodiment, the rear end of one of the two sets of second gears 10 is meshed with a fourth rack 20 through gears, and the front end of the other set of two sets of second gears 10 is meshed with a fifth rack 21 through gears. A second connecting plate 22 is fixedly connected between the fourth rack 20 and the fifth rack 21.

[0029] Specifically, during the movement of the second connecting plate 22, the fourth rack 20 meshes with one of the two sets of second gears 10, while the fifth rack 21 meshes with the other set of second gears 10, thereby causing the two sets of second gears 10 to rotate simultaneously.

[0030] In this embodiment, a first push block 23 is fixedly connected to the upper end of the base 1. The front end of the first push block 23 has an opening, and a first groove 24 is provided on the inner side of the first push block 23. A second slider 25 is slidably connected to the inner side of the first groove 24. The lower end of the second slider 25 is fixedly connected to the second connecting plate 22. A cylinder 26 is installed on the upper end of the first push block 23, and the output end of the cylinder 26 is fixedly connected to the second slider 25.

[0031] Specifically, starting cylinder 26 causes the output end of cylinder 26 to push the second slider 25 and the second connecting plate 22 to move.

[0032] In this embodiment, the front end of the first push block 23 is movably connected to the second push block 27. The inner side of the second push block 27 is provided with a second groove 28. The inner side of the second groove 28 is slidably connected to the third slider 29. The lower end of the third slider 29 is fixedly connected to the first connecting plate 19. The upper end of the third slider 29 passes through the second groove 28 and is fixedly connected to the slide plate 30. The second push block 27 is fixedly connected to both sides with a sixth rack 31. The sixth rack 31 meshes with the first gear 4.

[0033] Specifically, as the first connecting plate 19 pushes the second push block 27 forward, the sixth rack 31 meshes with the first gear 4 to make it rotate, which in turn causes the first gear 4 to mesh with the first rack 5, causing the clamping plate 8 to move away from the operating table 2. Then, the second push block 27 continues to move forward, which can push the cut workpiece off the surface of the operating table 2. When cutting the next workpiece, the cylinder 26 outputs in the opposite direction, driving the second push block 27 to move backward. When moving backward, the sixth rack 31 will mesh with the first gear 4 to make it rotate in the opposite direction, which will then cause the clamping plate 8 to move back onto the operating table 2 and clamp the workpiece.

[0034] It should be noted that this utility model is a transfer mechanism for a laser cutting machine. During use, the cylinder 26 is activated, causing the second slider 25 to move along with the second connecting plate 22. At this time, the fourth rack 20 meshes with one set of the two sets of second gears 10, and the fifth rack 21 meshes with the other set of second gears 10, causing both sets of second gears 10 to rotate simultaneously, driving the first connecting rod 11 to deflect. Then, through the rotatable connection of the second rotating block 12 and the third rotating block 13, the second connecting rod 14 deflects, thereby pushing the second push block 27 forward. At this time, the first gear 4 meshes with the sixth rack 31... When the gear meshes and rotates, the first gear 4 will simultaneously mesh with the first rack 5, causing the two sets of clamping plates 8 to move away from each other and be removed from the surface of the operating table 2. Then, the second pusher 27 continues to move forward to send the cut workpiece out of the operating table 2. When cutting the next workpiece, the command cylinder 26 outputs in the opposite direction, causing the second pusher 27 to move backward. When moving backward, the sixth rack 31 will mesh with the first gear 4 again to make it rotate in the opposite direction, which will then cause the two sets of clamping plates 8 to move closer to each other and back to the surface of the operating table 2 to clamp the workpiece. After fixing the workpiece, the laser cutting operation is performed.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
