Description

Technical Field

[0001] This utility model relates to the field of sheet metal laser cutting equipment, and in particular to a sheet metal laser cutting anti-deviation clamping and fixing device. Background Technology

[0002] Laser cutting is a processing technology that uses a high-power-density laser beam to vaporize or melt materials, thereby achieving precise cutting. It is widely used in the field of sheet metal processing and has advantages such as high cutting accuracy, small heat-affected zone, and strong adaptability.

[0003] In the existing technology, the clamping and fixing device for laser cutting of sheet metal usually adopts a simple clamping plate structure. The sheet metal is clamped and fixed by manual or electric drive of the clamping plate, and then the laser cutting body completes the cutting operation under the drive of the moving bracket.

[0004] However, existing devices have obvious shortcomings: on the one hand, laser cutting is mostly an exposed operation, and the sparks and debris generated during the cutting process are easy to fly around. There is a lack of effective protective structure, which poses safety hazards and is not conducive to a clean working environment. Therefore, a plate laser cutting anti-deviation clamping and fixing device is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a clamping and fixing device for preventing deviation in laser cutting of sheet metal. It aims to improve the problem that laser cutting in the prior art is mostly an exposed operation, and the sparks and debris generated during the cutting process are easy to fly around. There is a lack of effective protective structure, which poses safety hazards and is not conducive to a clean working environment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a plate laser cutting anti-deviation clamping and fixing device, including a worktable, a movable bracket slidably connected to the upper outer wall of the worktable, a laser cutting body slidably connected to the upper end of the movable bracket, a protective plate slidably connected to the inner wall of the worktable, a motor fixedly connected to one side of the outer wall of the worktable, a threaded rod fixedly connected to the output end of the motor, a clamping plate threadedly connected to the threaded rod through a threaded sleeve, a long rod fixedly connected to the lower inner wall of the clamping plate, a sliding groove is opened on the inner wall of the protective plate, the inner wall of the sliding groove is slidably connected to the outer wall of the long rod, and multiple sets of ball bearings are rotatably connected to the inner wall of the sliding groove.

[0007] As a further description of the above technical solution: The inner wall of the workbench has a groove, and the outer wall of the clamping plate is slidably connected to the inner wall of the groove.

[0008] As a further description of the above technical solution: The inner wall of the workbench has an installation groove, and the outer wall of the protective plate is slidably connected to the inner wall of the installation groove.

[0009] As a further description of the above technical solution: Two sets of clamps are symmetrically arranged, and the lower outer walls of the two sets of clamps are in contact with the outer wall of the workbench.

[0010] As a further description of the above technical solution: The outer wall of the threaded rod near the motor passes through the inner wall of the worktable and is rotatably connected, while the other end of the threaded rod is rotatably connected to the inner wall of the worktable through a bearing.

[0011] As a further description of the above technical solution: The inner wall of the workbench is provided with a guide groove, and a long rod passes through the guide groove and is slidably connected to the guide groove.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the protective plate is in a low position in the initial state of the device. When the clamping plate fixes the plate, the protective plate can rise synchronously. This not only avoids the obstruction of the plate being placed in the initial state, but also effectively blocks the splashing of sparks and debris during the cutting process, greatly improving the safety of operation and the cleanliness of the working environment.

[0013] 2. In this utility model, by setting multiple sets of balls, the sliding friction between the long rod and the sliding groove of the protective plate is converted into rolling friction, which greatly reduces frictional resistance, reduces the wear rate of components, and thus extends the overall service life of the equipment.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-3 This utility model provides an embodiment of a laser cutting anti-deviation clamping and fixing device for sheet metal, comprising a worktable 1, a movable support 2 slidably connected to the upper outer wall of the worktable 1, the movable support 2 driving the laser cutting body 3 to move horizontally above the worktable 1, realizing cutting operations at different positions of the sheet metal, the upper end of the movable support 2 is slidably connected to the laser cutting body 3, the laser cutting body 3 can slide laterally on the movable support 2, thereby adjusting the specific cutting position and improving the flexibility and accuracy of cutting, a protective plate 4 slidably connected to the inner wall of the worktable 1, the protective plate 4 can slide vertically within the worktable 1, and rises during cutting to protect the cutting area and prevent sparks and debris from flying, a motor 5 is fixedly connected to one side of the outer wall of the worktable 1, the motor 5 provides power to the entire clamping and fixing mechanism, and a threaded rod 6 is fixedly connected to the output end of the motor 5. Machine 5 can drive the threaded rod 6 to rotate to achieve the horizontal movement of clamping plate 7. The threaded rod 6 is threadedly connected to clamping plate 7 through threaded sleeve. Clamping plate 7 is used to clamp and fix the plate placed on workbench 1 to prevent the plate from shifting during laser cutting. A long rod 11 is fixedly connected to the inner wall of the lower end of clamping plate 7. When clamping plate 7 moves, long rod 11 can slide in sliding groove 9 of protective plate 4, thereby driving protective plate 4 to move synchronously. Sliding groove 9 is opened on the inner wall of protective plate 4. The inner wall of sliding groove 9 is slidably connected to the outer wall of long rod 11. Sliding groove 9 provides space for sliding of long rod 11, and reduces friction when long rod 11 slides through internal ball bearings 10. Multiple sets of ball bearings 10 are rotatably connected to the inner wall of sliding groove 9. The ball bearings 10 convert the sliding friction between long rod 11 and sliding groove 9 into rolling friction, greatly reducing frictional resistance, reducing component wear, and extending equipment service life.

[0018] Reference Figures 2-4The inner wall of the workbench 1 has a groove 8. The outer wall of the clamping plate 7 is slidably connected to the inner wall of the groove 8. The groove 8 provides guidance and limit for the horizontal movement of the clamping plate 7, ensuring that the clamping plate 7 maintains stable linear movement during the movement. The inner wall of the workbench 1 has an installation groove 13. The outer wall of the protective plate 4 is slidably connected to the inner wall of the installation groove 13. The installation groove 13 provides installation space and guidance for the vertical sliding of the protective plate 4, ensuring that the protective plate 4 can be smoothly raised and lowered. There are two sets of clamping plates 7. The lower outer walls of the two sets of clamping plates 7 are attached to the outer wall of the workbench 1. The two sets of clamping plates 7 are used together to clamp the plate from both sides, making the plate more secure.

[0019] Reference Figures 2-4 The outer wall of the threaded rod 6 near the motor 5 passes through the inner wall of the workbench 1 and is rotatably connected. The other end of the threaded rod 6 is rotatably connected to the inner wall of the workbench 1 through a bearing, so that the threaded rod 6 can rotate stably under the drive of the motor 5, while ensuring the stability of its connection with the workbench 1. A guide groove 12 is provided on the inner wall of the workbench 1. The long rod 11 passes through the guide groove 12 and is slidably connected to the guide groove 12. The guide groove 12 further guides the movement of the long rod 11, ensuring that the long rod 11 and the clamping plate 7 maintain linear motion during the movement, and improving the stability of clamping.

[0020] Working principle: When using the device, first place the plate to be cut between the two sets of clamping plates 7 on the worktable 1, then start the motor 5. The output end of the motor 5 drives the threaded rod 6 to rotate. Since the threaded rod 6 is threadedly connected to the clamping plate 7 through the threaded sleeve, and the clamping plate 7 can only move horizontally under the guidance of the groove 8 and the guide groove 12, the two sets of clamping plates 7 will move closer to each other to clamp and fix the plate, preventing it from shifting during laser cutting.

[0021] During the movement of the clamping plate 7, the long rod 11 at its lower end will slide in the sliding groove 9 of the protective plate 4. At the same time, multiple sets of balls 10 in the sliding groove 9 will roll with the movement of the long rod 11, converting sliding friction into rolling friction, reducing frictional resistance and component wear. As the long rod 11 slides, it will push the protective plate 4 to move vertically upward along the mounting groove 13 until the protective plate 4 forms a closed protection for the laser cutting area.

[0022] Afterwards, the control mobile support 2 drives the laser cutting body 3 to move above the worktable 1. The laser cutting body 3 emits a laser beam to precisely cut the plate. After the cutting is completed, the motor 5 is started in reverse to make the two sets of clamping plates 7 move away from each other. The long rod 11 moves with the clamping plates 7 and pulls the protective plate 4 downward to reset. At this time, the cut plate can be taken out, and one operation process is completed.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
