Description

Technical Field

[0001] This utility model relates to the field of laser cutting device technology, specifically a working platform for a laser cutting machine. Background Technology

[0002] The core function of a laser cutting machine platform is to support the material to be processed, ensuring its stable and flat position during the cutting process and providing fundamental support for precise cutting. It needs to be adaptable to materials of different sizes and materials, such as metal and non-metal sheets, and must also possess characteristics such as resistance to laser burns and high-temperature resistance to prevent damage to itself from affecting processing. Some platforms are designed with grid, honeycomb, or strip structures to reduce laser reflection and material adhesion, facilitating waste disposal and cleaning. Furthermore, the platform often works with positioning devices (such as clamps and scales) to achieve precise material positioning, and its height can be adjusted to accommodate different focal length requirements, ensuring cutting quality and efficiency. It is an indispensable support and auxiliary component in laser cutting equipment.

[0003] The existing Chinese utility model patent with publication number CN211028614U discloses a cutting platform for a laser cutting machine. This platform includes a base, a slag assembly mounted on the base, and a slag removal assembly. The slag assembly includes a rectangular frame fixedly mounted on the top of the base and multiple slag bars mechanically mounted on the rectangular frame. The slag removal assembly includes multiple telescopic cylinders, a grid-type lifting frame, and multiple sets of slag removal blades mechanically mounted on the lifting frame. Each set of slag removal blades includes two slag removal blades clamped on both sides of the same slag bar. The bottom of the telescopic cylinders is mechanically mounted on the base, and the lifting frame is mechanically mounted on the top of the telescopic cylinders. The beneficial effects are: the telescopic cylinders drive the lifting frame and the slag removal blades to rise and fall together. When the slag removal blades rise, they push the molten slag falling on both sides of the slag bars upwards, thus separating the slag from the slag bars and achieving slag removal; when the slag removal blades descend, the top of the slag bars is positioned above the slag removal blades, allowing the slag bars to normally function as supports for the material to be processed.

[0004] Currently, the working platforms of laser cutting machines still have the following problems:

[0005] When operating a laser cutting machine, it is necessary to continuously provide thermal protection for the laser head, optical path, or key areas of the worktable to avoid damage to equipment components or safety hazards caused by high-temperature radiation. Currently, most existing thermal protection structures are fixed installation designs, which cannot be moved and adjusted according to processing needs, increasing the complexity of equipment operation and safety risks, and making it difficult to meet the requirements of safe and efficient laser cutting operations. Utility Model Content

[0006] The purpose of this utility model is to provide a working platform for a laser cutting machine to solve the safety problem caused by the lack of heat insulation during operation of the laser cutting machine mentioned in the background art.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0008] This utility model provides a working platform for a laser cutting machine, including a worktable, a support frame, a movable crossbeam, a bottom crossbeam, and a second cylinder. The support frame is fixedly installed on both sides of the worktable, and a movable crossbeam is horizontally arranged at the bottom end of the worktable. A bottom crossbeam is horizontally arranged below the movable crossbeam. The middle of the bottom crossbeam contacts the top of the second cylinder below it. Connecting plates are connected to both ends of the movable crossbeam, and a piston rod is inserted through one end of the connecting plate. One end of the piston rod is movably connected to the first cylinder. Multiple sets of heat insulation plates are equidistantly arranged in the middle of the movable crossbeam.

[0009] Preferably, the workbench is fixedly installed inside the card plate, and the card plate is laterally located between the module frames. The workbench is equidistantly located between the module frames, and the rear of the module frames is connected to the mounting bracket.

[0010] Preferably, the connecting plate has a positioning hole inside, and the angle between the "L"-shaped connecting plates is 90°, and one side of the cylinder is fixedly connected to the side of the support frame.

[0011] Preferably, the bottom crossbeam includes fixed vertical plates that are fixedly installed at equal intervals at the rear, and a slide rail is provided in the lower middle part of the fixed vertical plate, and the bottom crossbeam is located inside the slide rail, with the top of the fixed vertical plate located on one side of the movable crossbeam.

[0012] Preferably, a connecting plate is installed on the side of the fixed vertical plate and connected to the bottom crossbeam, and a ball bearing platform is connected to the top of the connecting plate.

[0013] Preferably, the ball bearing platform is horizontally located below the heat insulation plate, and the heat insulation plate is located between every two sets of worktables.

[0014] Preferably, the mounting frame, the movable crossbeam, and the bottom crossbeam are all located on the same horizontal line, and a bracket plate is provided near the bottom of both ends of the mounting frame, and the bracket plate is fixedly installed above the support frame.

[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0016] 1. When the laser cutting machine's working platform is in operation, the heat insulation plate is connected to the connecting plate, piston rod, and cylinder one. The cylinder one drives the piston rod to reciprocate linearly inside the cylinder through the pressure difference of the compressed gas, causing the heat insulation plate to move in parallel with the piston rod. This prevents the heat and materials from the laser cutting from damaging the ball bearing platform, thus protecting the equipment. At the same time, it can dynamically adapt to the needs of the cutting operation, making the protective equipment highly flexible during use and improving the safety effect of the equipment during operation.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] Please see Figures 1-5 A working platform for a laser cutting machine includes a worktable 1, a support frame 2, a moving crossbeam 3, a bottom crossbeam 4, and a cylinder 2 5. The worktable 1 is fixedly installed inside a mounting plate 14, and the mounting plate 14 is laterally located between module frames 13. The worktable 1 is equidistantly located between the module frames 13, and the rear of the module frames 13 is connected to a mounting frame 11.

[0028] In this embodiment, the mounting frame 11, the movable crossbeam 3, and the bottom crossbeam 4 are all located on the same horizontal line, and a bracket plate 12 is provided near the bottom of both ends of the mounting frame 11, and the bracket plate 12 is fixedly installed above the support frame 2.

[0029] The working platform of the laser cutting machine of this utility model has a spiked worktable 1 that can reduce material adhesion and significantly reduce the contact between the platform and the material surface. It also facilitates the discharge of debris and allows residue to fall through the gap. Multiple sets of worktables 1 are fixedly connected by a clamping plate 14 to form a support platform to support the equipment for processing. Each set of worktables 1 can be moved to one side of the mounting frame 11 through the modular frame 13 to adjust the spacing between the worktables 1 and achieve effective support.

[0030] For details, please refer to the following: Figure 4 As shown, the support frame 2 is fixedly installed on both sides of the workbench 1, and a movable crossbeam 3 is horizontally arranged at the bottom of the workbench 1. The two ends of the movable crossbeam 3 are connected to the connecting plates 31, and a piston rod 33 is inserted through one end of the connecting plate 31. One end of the piston rod 33 is movably connected to the cylinder 32. Multiple sets of heat insulation plates 34 are equidistantly arranged in the middle of the movable crossbeam 3.

[0031] In this embodiment, the connecting plate 31 has a positioning hole inside, and the angle between the "L"-shaped connecting plates 31 is 90°. One side of the cylinder 32 is fixedly connected to the side of the support frame 2. The ball bearing platform 43 is horizontally located below the heat insulation plate 34, and the heat insulation plate 34 is located between every two sets of worktables 1.

[0032] The working platform of this utility model of a laser cutting machine has a heat insulation plate 34 movably connected to a connecting plate 31, a piston rod 33, and a cylinder 32. The reciprocating motion of the piston rod 33 driven by the cylinder 32 allows the heat insulation plate 34 to move horizontally above the ball bearing platform 43, thereby providing parallel pushing protection for the ball bearing platform 43 and preventing damage from the heat and materials generated by laser cutting. This protects the equipment and maintains its normal operation. The heat insulation plate 34 moves together with the processing equipment, eliminating the need for separate equipment adjustments, reducing operating steps, and improving the flexibility of equipment protection during use.

[0033] For details, please refer to the following: Figure 5 As shown, a bottom crossbeam 4 is horizontally arranged below the movable crossbeam 3. The middle of the bottom crossbeam 4 contacts the top of the cylinder 2 5 below it. The bottom crossbeam 4 includes a fixed vertical plate 41 that is fixedly installed at equal intervals at the rear. A slide rail 44 is arranged in the middle and lower part of the fixed vertical plate 41. The bottom crossbeam 4 is located inside the slide rail 44. The top of the fixed vertical plate 41 is located on one side of the movable crossbeam 3.

[0034] In this embodiment, a connecting plate 42 connected to the bottom crossbeam 4 is installed on the side of the fixed vertical plate 41, and a ball bearing platform 43 is connected to the top of the connecting plate 42.

[0035] The working platform of the laser cutting machine of this utility model has a ball bearing platform 43 located below the heat insulation plate 34. When the heat insulation plate 34 moves left and right by the cylinder 32, the ball bearing platform 43 and the heat insulation plate 34 are staggered. The staggered ball bearing platform 43 can be raised and lowered in conjunction with the cylinder 5, so that the ball bearing platform 43 is located between each group of worktables 1, thus isolating multiple groups of worktables 1. The balls on the surface of the ball bearing platform 43 can more smoothly transport or adjust the position of the processed items on the surface of the worktable 1.

[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
