Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping device technology, and in particular to a laser cutting lens clamping device. Background Technology
[0002] Existing laser cutting lens clamping devices are mostly fixed, requiring the entire device to be moved to adjust the lateral position of the lens, which is cumbersome and lacks precision. At the same time, the angle adjustment lacks a stable locking mechanism, which can easily affect the cutting accuracy due to vibration and displacement. The clamping force is difficult to control; if it is too hard, it can damage the optical components of the lens, while if it is too loose, it will cause shaking, which brings certain adverse effects to the user experience. In order to overcome the shortcomings of the existing technology, we propose a laser cutting lens clamping device. Utility Model Content
[0003] The main purpose of this invention is to provide a laser cutting lens clamping device, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A laser cutting lens clamping device includes a cutting table with two symmetrical rectangular slots on its surface. A guide rod is fixedly connected within each slot, and a sliding upright plate is slidably connected to the outer surface of the guide rod. A first connecting plate is fixedly connected to the upper end of each sliding upright plate. One of the first connecting plates has multiple insertion holes on one side surface. A rotating plate is provided on the corresponding surface of each of the two first connecting plates, and a first connecting rod is fixedly connected to one side of each rotating plate. One end of one of the first connecting rods passes through the first connecting plate and is fixedly connected to a limit block. A spring is sleeved on the outer surface of the first connecting rod located between the limit block and the first connecting plate. The other first connecting rod… The other end of the rod passes through the first connecting plate and is fixedly connected to the second connecting plate. A handle is fixedly connected to one side of the second connecting plate. A fixing block is fixedly connected to the front end of one of the rotating plates, and a plug rod is fixedly connected to one side of the fixing block. A fixing plate is fixedly connected between the two rotating plates. A rotating handle is provided above the fixing plate, and a second connecting rod is fixedly connected to the lower end of the rotating handle. A first bevel gear is fixedly connected to the outer surface of the second connecting rod. Second bevel gears mesh with both sides of the first bevel gear, and a threaded rod is fixedly connected to one side of the second bevel gear. A moving block is threadedly connected to the outer surface of the threaded rod. A clamping block is fixedly connected to the front end of the moving block, and a laser cutting component is clamped between the two clamping blocks.
[0005] Preferably, the insertion holes are arranged in a ring array on the surface of the first connecting plate, and the diameter of the insertion holes is adapted to the diameter of the insertion rod, and the insertion rod and the insertion holes are in clearance fit.
[0006] Preferably, the sliding plate has a sliding hole in the middle that matches the guide rod, the inner wall of the sliding hole is in contact with the outer surface of the guide rod, and the sliding plate and the guide rod form a sliding structure through the sliding hole.
[0007] Preferably, one end of the spring abuts against one side surface of the limiting block, and the other end of the spring abuts against one side surface of the first connecting plate.
[0008] Preferably, the end of the second connecting rod away from the handle is rotatably connected to the inner cavity of the fixed plate via a bearing, and the end of the threaded rod away from the second bevel gear is rotatably connected to the inner cavity of the fixed plate via a bearing.
[0009] Preferably, each of the clamping blocks has a rubber pad fixedly connected to its opposite surface. The surface of the rubber pad is provided with anti-slip texture, and the shape of the clamping block is adapted to the outer contour of the laser cutting component.
[0010] Compared with the prior art, the present invention has the following beneficial effects: This laser-cutting lens clamping device achieves rapid clamping and fixation of laser-cut components through a coordinated structure of a rotating handle, bevel gear transmission, and threaded rod driving the clamping block. The clamping block's arc-shaped design, which adapts to the lens's outer contour, and its surface anti-slip rubber pads not only prevent mechanical damage to the lens during clamping but also enhance clamping stability by increasing the coefficient of friction. This effectively solves the problem of lens precision damage caused by loose clamping or excessive squeezing in traditional devices, significantly improving operational convenience and clamping reliability.
[0011] This laser cutting lens clamping device allows for flexible adjustment of the lens's lateral position through the sliding cooperation of a sliding vertical plate and a guide rod. With the help of a spring-reset plug rod and a ring array of plug holes, it enables precise multi-angle adjustment and locking of the lens. This dual adjustment mechanism overcomes the limitations of traditional clamping devices in terms of position and angle adjustment, meets the positioning requirements of different cutting scenarios, reduces operational complexity, and improves the adaptability and processing accuracy of laser cutting operations.

[0014] 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.
[0015] Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a laser cutting lens clamping device includes a cutting table 1. Two rectangular grooves 2 are symmetrically formed on the surface of the cutting table 1. A guide rod 3 is fixedly connected within each rectangular groove 2. A sliding plate 4 is slidably connected to the outer surface of the guide rod 3. A sliding hole adapted to the guide rod 3 is formed in the middle of the sliding plate 4. The inner wall of the sliding hole fits against the outer surface of the guide rod 3. The sliding plate 4 and the guide rod 3 form a sliding structure through the sliding hole. A first connecting plate 5 is fixedly connected to the upper end of each of the two sliding plates 4. One side surface of one of the first connecting plates 5 has multiple insertion holes 6. The insertion holes 6 are located on the first connecting plate 5. The surface is arranged in a ring array. Rotating plates 7 are provided on the corresponding surfaces of the two first connecting plates 5. A first connecting rod 8 is fixedly connected to one side of each rotating plate 7. One end of one of the first connecting rods 8 passes through the first connecting plate 5 and is fixedly connected to a limiting block 9. A spring 10 is sleeved on the outer surface of the first connecting rod 8 located between the limiting block 9 and the first connecting plate 5. One end of the spring 10 abuts against one side of the limiting block 9, and the other end abuts against one side of the first connecting plate 5. The other end of the other first connecting rod 8 passes through the first connecting plate 5 and is fixedly connected to a second connecting plate 11. A handle 12 is fixedly connected to one side of a rotating plate 7. A fixing block 13 is fixedly connected to the front end of a rotating plate 7. A plug rod 14 is fixedly connected to one side of the fixing block 13. The diameter of the plug rod 14 is adapted to the diameter of the plug hole 6. The plug rod 14 and the plug hole 6 are clearance fit. A fixing plate 15 is fixedly connected between the two rotating plates 7. A rotating handle 16 is provided above the fixing plate 15. A second connecting rod 17 is fixedly connected to the lower end of the rotating handle 16. The end of the second connecting rod 17 away from the rotating handle 16 is rotatably connected to the inner cavity of the fixing plate 15 through a bearing. A first connecting rod is fixedly connected to the outer surface of the second connecting rod 17. A first bevel gear 18 is provided, with second bevel gears 19 meshing on both sides of the first bevel gear 18. A threaded rod 20 is fixedly connected to one side of the second bevel gear 19. The end of the threaded rod 20 away from the second bevel gear 19 is rotatably connected to the inner cavity of the fixed plate 15 through a bearing. A moving block 21 is threadedly connected to the outer surface of the threaded rod 20. A clamping block 22 is fixedly connected to the front end of the moving block 21. Rubber pads are fixedly connected to the opposite surfaces of the clamping blocks 22. The surface of the rubber pads is provided with anti-slip texture. The shape of the clamping blocks 22 is adapted to the outer contour of the laser cutting component 23. The laser cutting component 23 is clamped between the two clamping blocks 22.
[0016] It should be noted that this utility model is a laser cutting lens clamping device. In use, the laser cutting component 23 is first placed between two clamping blocks 22. The rotating handle 16 is rotated, which drives the second connecting rod 17 to rotate. The second connecting rod 17 drives the first bevel gear 18 to rotate. Since the first bevel gear 18 meshes with the second bevel gears 19 on both sides, the rotation of the first bevel gear 18 will drive the second bevel gear 19 to rotate. The rotation of the second bevel gear 19 will then drive the threaded rod 20 to rotate. The rotation of the threaded rod 20 causes the moving block 21, which is threaded to it, to move relative to the threaded rod 20, thereby driving the clamping blocks 22 to clamp and fix the laser cutting component 23. The rubber pad can prevent the clamping blocks 22 from damaging the laser cutting component 23. At the same time, the anti-slip texture can increase the friction and improve the stability of the clamping. When it is necessary to adjust the lateral position of the laser cutting component 23, the sliding plate 4 is pushed. The sliding plate 4 slides on the guide rod 3 through the sliding hole, thereby driving the entire clamping structure to move laterally on the cutting table 1 to achieve position adjustment. When the angle of the laser cutting assembly 23 needs to be adjusted, pull the handle 12. The handle 12 drives the first connecting rod 8 to move through the second connecting plate 11. The first connecting rod 8 drives the rotating plate 7 to move. The rotating plate 7 drives the insertion rod 14 on the fixing block 13 to be pulled out of the insertion hole 6. At this time, the spring 10 is compressed. Then rotate the rotating plate 7. The rotating plate 7 drives the fixing plate 15 and the laser cutting assembly 23 to rotate to the required angle. Release the handle 12. Under the elastic force of the spring 10, the limiting block 9 will drive the first connecting rod 8 to move, thereby driving the rotating plate 7 to reset, so that the insertion rod 14 is inserted into the corresponding insertion hole 6, and the angle is fixed.
