Description
Technical Field
[0001] The utility model relates to the technical field of laser cutting clamping, in particular to a clamping mechanism for laser cutting. Background Art
[0002] During the laser cutting process, a clamping mechanism is required to clamp and fix the plate. However, the existing clamping mechanisms have poor fixing effects on the plate, resulting in easy deviation of the plate during the cutting process. This not only affects the cutting accuracy and efficiency but also may cause material waste. More problematically, these clamping mechanisms lack flexibility and cannot easily adapt to plates of different specifications and sizes, thus greatly limiting the application range of the clamping mechanism. In addition, once the plate is fixed by the clamping mechanism, its position becomes fixed, which brings great inconvenience to users. In actual operation, it is often necessary to adjust the angle of the plate according to specific requirements, but the existing clamping mechanisms cannot provide such a function. This limitation makes these clamping mechanisms difficult to meet the diverse needs of laser cutting, thereby reducing their practicality and efficiency in actual applications. Therefore, we have proposed a clamping mechanism for laser cutting. Summary of the Invention

[0030] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0031] A clamping mechanism for laser cutting, comprising a base 1. In the middle of the front end of the base 1, a controller 2 is fixedly connected. On the left and right upper parts of the base 1, support plates 3 are fixedly connected respectively. At the upper right part of the right support plate 3, a driver 4 is arranged. The output end of the driver 4 penetrates through the right end of the right support plate 3 and is fixedly connected with a driving screw rod 5. The left and right ends of the driving screw rod 5 are movably connected with the opposite surfaces of the two support plates 3 through bearings respectively. Between the lower parts of the opposite surfaces of the two support plates 3, two limiting rods 6 are fixedly connected together. Between the left part of the outer surface of the two limiting rods 6 and the left part of the outer surface of the driving screw rod 5 and between the right parts of the outer surfaces, adjusting plates 7 are inserted and movably connected together. And the two adjusting plates 7 are both threadedly connected with the driving screw rod 5. On the upper parts of the opposite surfaces of the two adjusting plates 7, adjusting shafts 8 are inserted and movably connected through bearings;
[0032] On the opposite surfaces of the two adjusting shafts 8, clamping frames 9 are fixedly connected respectively. In the middle of the upper ends of the two clamping frames 9, fixing mechanisms 10 are inserted and movably connected. On the lower parts of the opposite surfaces of the two clamping frames 9, three fixing rods 11 are fixedly connected respectively. In the middle of the right ends of the three left fixing rods 11, telescopic rods 12 are fixedly connected. And the right ends of the three telescopic rods 12 are respectively inserted and movably connected with the left ends of the three right fixing rods 11. A plurality of tooth grooves 13 are formed in the upper ends of the six fixing rods 11.
[0033] In this embodiment, the fixing mechanism 10 includes a fixing clamping plate 101. At the lower end of the fixing clamping plate 101, an anti-slip pad 102 is fixedly connected. At the front and rear upper parts of the upper end of the fixing clamping plate 101, limiting frames 103 are fixedly connected respectively. And the outer surfaces of the two limiting frames 103 are inserted and movably connected with the upper shelf walls of the clamping frames 9. In the middle of the upper end of the fixing clamping plate 101, an adjusting screw rod 104 is inserted and movably connected through a bearing. And the outer surface of the adjusting screw rod 104 is threadedly connected with the upper shelf wall of the clamping frame 9. At the upper end of the adjusting screw rod 104, an adjusting handle 105 is fixedly connected; The anti-slip pad 102 is made of rubber material. The limiting frame 103 is arranged in a U-shaped structure. And the upper shelf wall of the limiting frame 103 is flush with the upper end surface of the adjusting screw rod 104; The clamping frame 9 is arranged in an L-shaped structure. The length of the telescopic rod 12 is the same as the length of the fixing rod 11. The tooth groove 13 is arranged in a triangular structure.
[0034] Through the above solution: Place the sheet to be laser cut on the fixed rod 11, then start the driver 4 to drive the drive screw 5 to move two adjusting plates 7 towards the middle, so that the two clamping brackets 9 move towards the middle together to clamp and fix the sheet from both left and right sides. Then, rotate the adjusting handle 105 to drive the adjusting screw rod 104 to rotate, and through the guiding and limiting of the limiting frame 103, the fixed clamping plate 101 stably drives the anti-slip pad 102 to move downward, which can cooperate with the fixed rod 11 to clamp and fix the sheet from both upper and lower sides, thus strengthening the clamping and fixing effect on the sheet, improving the stability of the sheet, making the sheet not prone to deviation during the cutting process, improving the accuracy and efficiency of the sheet during cutting, and also avoiding waste of materials. Moreover, the distance between the two clamping brackets 9 and the distance between the anti-slip pad 102 and the fixed rod 11 can be flexibly adjusted, so that the clamping mechanism can adapt to sheets of different specifications and sizes, improving the flexibility of the clamping mechanism and expanding the applicable range of the clamping mechanism.
[0035] In this embodiment, the outer surfaces of the two adjusting shafts 8 are both fixedly connected with first gears 14 in an inserted manner. The middle parts of the opposite surfaces of the two adjusting shafts 8 are both fixedly connected with indicating needles 15 in an inserted manner. The upper parts of the opposite surfaces of the two adjusting plates 7 are both fixedly connected with indicating rings 16. The middle parts of the opposite surfaces of the two adjusting plates 7 are both provided with drive motors 17. The output ends of the two drive motors 17 respectively penetrate through the two adjusting plates 7 and are fixedly connected with second gears 18 in an inserted manner. Moreover, the opposite surfaces of the two second gears 18 are respectively movably connected with the opposite surfaces of the two adjusting plates 7 through bearings; the outer surface of the first gear 14 meshes with the outer surface of the second gear 18, and the diameter length of the first gear 14 is larger than the diameter length of the second gear 18; the drive motors 17 and the driver 4 are both electrically connected to the controller 2, and the drive screw 5 and the two limiting rods 6 are distributed in a triangular shape.
[0036] Through the above solution: Start the drive motor 17 to drive the second gear 18 to rotate, and then through the meshing transmission between the second gear 18 and the first gear 14, the adjusting shaft 8 drives the clamping bracket 9 to rotate slowly, so that the angle of the fixed sheet can be rotated and adjusted. Moreover, when the adjusting shaft 8 rotates, it also drives the indicating needle 15 to rotate together. By observing the position of the indicating needle 15 penetrating through the indicating ring 16, the angle of the sheet can be accurately determined, so as to facilitate flexible adjustment of the angle of the sheet according to specific requirements, meet the diverse requirements of laser cutting, and also improve the practicality and efficiency of the clamping mechanism in actual application.
[0037] It should be noted that, first, the entire clamping mechanism is installed and fixed on the laser cutting machine, and then the plate to be laser cut is placed on the fixed rod 11. At this time, the controller 2 can be used to control the driver 4 to start, so that the driving screw 5 drives the two adjusting plates 7 to move towards the middle, and the limiting rod 6 is used to guide and limit the adjusting plates 7, which can improve the stability of the adjusting plates 7 during movement. That is, the two adjusting plates 7 can drive the two clamping brackets 9 to move towards the middle together to clamp the plate. At the same time as the fixed rod 11 moves, the telescopic rod 12 expands and contracts within the corresponding fixed rod 11, which can further improve the stability of the two clamping brackets 9. Then, with the cooperation of the fixing mechanism 10 and the fixed rod 11, the firm clamping of the plate can be achieved, thereby strengthening the clamping and fixing effect of the clamping mechanism on the plate, effectively improving the stability of the plate during laser cutting, ensuring the quality of laser cutting. When it is necessary to adjust the angle of the fixed plate, the controller 2 can be used to control the driving motor 17 to start, so that the adjusting shaft 8 drives the plate to rotate, and the angle of the plate can be adjusted according to the cutting requirements, so that the angle of the plate can be freely adjusted according to the needs, expanding the application range of the clamping mechanism and also improving the practicability.
