Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and specifically to a laser cutting machine with a concealable lifting platform. Background Technology

[0002] A laser cutting machine uses a laser emitted from a laser source. After passing through an optical path system, the laser beam is focused into a high-power-density laser beam. The laser beam then irradiates the workpiece to be cut on the processing platform. As the relative position of the laser beam and the workpiece moves, the workpiece is ultimately cut.

[0003] Chinese utility model patent with announcement number CN221473860U discloses a laser cutting machine. The prior art has the following defects: the toothed plate structure on its working platform is used to support and position the workpiece to be cut. However, since the toothed plate structure is a fixed structure and there is no lifting platform, the surface of the workpiece is easily scratched when loading and unloading the workpiece.

[0004] Therefore, there is still room for improvement in existing technologies. Utility Model Content

[0005] To address the problem that the fixed toothed plate structure in existing technologies easily scratches the workpiece surface when it is loaded onto the work platform, this utility model proposes a laser cutting machine with a concealable lifting platform.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows:

[0007] A laser cutting machine with a concealable lifting platform includes a frame, a processing platform mounted on the frame, multiple sets of positioning toothed plates fixed at intervals on the processing platform, and a lifting platform movably mounted between adjacent sets of positioning toothed plates. A drive assembly for raising and lowering the lifting platform is located below the processing platform. When the lifting platform is in a lowered position, it is concealed below the positioning toothed plates. A crossbeam is slidably mounted on the frame, located above the processing platform, and is movable back and forth relative to the X-axis of the processing platform. A slide block is slidably mounted on the crossbeam and is movable back and forth relative to the Y-axis of the processing platform. A laser cutting assembly is slidably mounted on the slide block and is movable back and forth relative to the Z-axis of the processing platform.

[0008] According to the above scheme, the lifting platform includes a movable seat, on which multiple support rods are fixed at intervals. The multiple support rods are respectively located between two adjacent sets of positioning tooth plates. The movable seat is driven to tilt and lift by a drive component. When the support rods rise, the upper surface of the support rods is higher than the upper surface of the positioning tooth plates.

[0009] According to the above scheme, there are two sets of drive components, which are arranged at intervals. Each drive component includes a cylinder and a connecting arm. The cylinder is tilted and fixed on the frame. One end of the connecting arm is connected to the output end of the cylinder, and the other end of the connecting arm is connected to the movable seat.

[0010] According to the above scheme, upright plates are fixed at both ends of the crossbeam, and the upright plates are slidably installed on the outer edge of the side wall of the frame; a toothed rail and a slide rail are installed at intervals on the outer edge of the side wall of the frame, with the toothed rail located below the slide rail; a motor and a slider are installed on the inner wall of the upright plate, with a drive wheel fixed at the output end of the motor, the drive wheel meshing with the toothed rail, and the slider slidingly connected to the slide rail.

[0011] According to the above scheme, the bottom of the gear rail is formed with teeth that open downwards, and the drive wheel is engaged with the teeth.

[0012] According to the above scheme, a motor is fixed on the first side of the slide block one, a gear is provided at the output end of the motor, and a tooth groove that meshes with the gear is provided on the outer wall of the crossbeam.

[0013] According to the above scheme, a motor three is fixed on the second side of the slide block one, a lead screw is fixed on the output end of the motor three, a slide block two is threadedly connected to the lead screw, and the slide block two is fixedly connected to the laser cutting assembly; and a slide rail two is fixed on the slide block one and slidably connected to the slide block two.

[0014] According to the above scheme, the laser cutting assembly includes a laser cutting head, and dust suction pipes are respectively provided on both sides of the laser cutting head.

[0015] According to the above scheme, multiple rolling rollers are installed on the frame surface on one side of the processing platform to facilitate loading and unloading.

[0016] According to the above scheme, a control box is provided at intervals on one side of the frame, and multiple height-adjustable support legs are fixed at intervals at the bottom of the frame. A movable base plate is also provided at the bottom of the frame, and multiple rollers are provided on the movable base plate.

[0017] The beneficial effects of this utility model are:

[0018] In this invention, the lifting platform is initially in an elevated position, which can be used to support the workpiece during loading. After the workpiece is loaded, the drive component drives the lifting platform to descend and hide it under the positioning tooth plate. At this time, the workpiece is positioned on multiple sets of positioning tooth plates. Then, the laser cutting component cuts the upper surface of the workpiece at any position. During the cutting process, the lifting platform will not be damaged by the laser cutting. After the cutting is completed, the drive component drives the lifting platform to rise and lift the workpiece, so that the workpiece is removed from the positioning tooth plate, thus achieving the purpose of not scratching the surface of the workpiece during loading and unloading.

[0028] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 7As shown, the laser cutting machine with a retractable lifting platform according to this utility model includes a frame 1, a processing platform 2 on the frame 1, multiple sets of positioning toothed plates 19 fixed at intervals on the processing platform 2, and a lifting platform movably arranged between adjacent sets of positioning toothed plates 19. A drive assembly for driving the lifting platform to rise and fall is provided below the processing platform 2. When the lifting platform is in the lowered position, the lifting platform is hidden below the positioning toothed plates 19; a crossbeam 8, which is slidably mounted on the frame 1 and located above the processing platform 2. The crossbeam 8 can move back and forth relative to the X-axis direction of the processing platform 2; a slide block 11, which is slidably mounted on the crossbeam 8 and can move back and forth relative to the Y-axis direction of the processing platform 2; and a laser cutting assembly 3, which is slidably mounted on the slide block 11 and can move back and forth relative to the Z-axis direction of the processing platform 2. With this setup, in the initial state, the lifting platform is in the raised position and can be used for support when loading workpieces. After the workpiece is loaded, the drive component drives the lifting platform to descend and hide it under the positioning toothed plate 19. At this time, the workpiece is positioned on multiple sets of positioning toothed plates 19. Then, the laser cutting component 3 cuts the upper surface of the workpiece at any position. During the cutting process, the lifting platform will not be damaged by the laser cutting. After the cutting is completed, the drive component drives the lifting platform to rise and lift the workpiece, so that the workpiece is removed from the positioning toothed plate 19, thus achieving the purpose of not scratching the surface of the workpiece when loading and unloading.

[0030] Furthermore, the positioning toothed plate lifting platform includes a movable base 22, on which multiple support rods 18 are fixed at intervals. The support rods 18 are located between two adjacent sets of positioning toothed plates 19. The movable base 22 is driven to tilt and rise via a drive assembly. When the support rods 18 rise, their upper surfaces are higher than the upper surfaces of the positioning toothed plates 19. This configuration ensures that when the support rods 18 are in the raised position, their upper surfaces are higher than the upper surfaces of the positioning toothed plates 19, providing support during workpiece loading. When the support rods 18 are in the lowered position, they are hidden beneath the positioning toothed plates 19, preventing damage during laser cutting.

[0031] Furthermore, the drive assembly comprises two sets, spaced apart. Each drive assembly includes a cylinder 20 and a connecting arm 21. The cylinder 20 is tilted and fixed to the frame 1. One end of the connecting arm 21 is connected to the output end of the cylinder 20, and the other end is connected to the movable seat 22. This configuration allows the cylinder 20 to drive the connecting arm 21, thereby tilting and raising / lowering the movable seat 22 and the positioning toothed plate 19.

[0032] It should be noted that the cylinder 20 of this utility model is installed at an angle. When the cylinder 20 is working, it drives the connecting arm 21 to tilt and lift the movable seat 22. When the support rod 18 is lowered, the support rod 18 is located below the positioning tooth plate 19 and will not be damaged by laser cutting, thus extending its service life.

[0033] Furthermore, each end of the crossbeam 8 is fixed with a vertical plate 9, which is slidably mounted on the outer edge of the side wall of the frame 1; a toothed rail 4 and a slide rail 5 are installed at intervals on the outer edge of the side wall of the frame 1, with the toothed rail 4 located below the slide rail 5; a motor 7 and a slider 17 are installed on the inner wall of the vertical plate 9, with a drive wheel fixed at the output end of the motor 7, the drive wheel meshing with the toothed rail 4, and the slider 17 slidably connected to the slide rail 5. With this configuration, when motor 7 is working, the crossbeam 8 can move back and forth relative to the X-axis of the processing platform 2. The gear rail 4 and slide rail 5 are installed at intervals on the outer edge of the side wall of the frame 1, eliminating the need for pre-reserved width space on the side wall surface of the frame 1. This allows for a narrower design of the side wall surface of the frame 1, resulting in a smaller distance between the loading / unloading position and the processing platform 2. This facilitates manual loading / unloading operations, reduces labor intensity, and increases loading / unloading efficiency. Furthermore, placing the gear rail 4 below the slide rail 5 reduces dust accumulation on the gear rail 4, decreasing maintenance frequency and costs, and making it more convenient to use.

[0034] Furthermore, the bottom of the gear rail 4 is formed with downward-facing teeth, and the drive wheel meshes with the teeth. This design protects the teeth and prevents dust accumulation from affecting their performance.

[0035] Furthermore, a second motor 12 is fixed to the first side of the slide block 11. The output end of the second motor 12 is equipped with a gear, and the outer wall of the crossbeam 8 is provided with a toothed groove that meshes with the gear. With this configuration, when the second motor 12 is working, it drives the slide block 11 to move relative to the crossbeam 8, thus enabling it to move back and forth relative to the Y-axis of the processing platform 2.

[0036] Furthermore, a motor 3 13 is fixed to the second side of the slide block 11, and a lead screw 14 is fixed to the output end of the motor 3 13. A slide block 2 16 is threadedly connected to the lead screw 14, and the slide block 2 16 is fixedly connected to the laser cutting assembly 3. A slide rail 2 15 is fixed to the slide block 11 and slidably connected to the slide block 2 16. With this configuration, the motor 3 13 drives the lead screw 14 and the slide block 2 16 to move in a threaded motion, thereby causing the slide rail 2 15 to drive the laser cutting assembly 3 to move linearly up and down along the slide rail 2 15, thus allowing it to move back and forth relative to the Z-axis of the processing platform 2.

[0037] Furthermore, the laser cutting assembly 3 includes a laser cutting head, with suction pipes on both sides of the laser cutting head. This design allows impurities generated during cutting to be removed and disposed of through the suction pipes, making it more environmentally friendly.

[0038] In practical applications, the suction pipe is connected to a dust collection and purification device.

[0039] Furthermore, multiple rolling rollers 6 are installed on the surface of the frame 1 on one side of the processing platform 2 to facilitate loading and unloading. This arrangement allows the rolling rollers 6 to assist in the rolling of workpieces during loading and unloading, saving time and effort, thereby improving loading and unloading efficiency.

[0040] Furthermore, a control box 10 is spaced apart on one side of the frame 1, and multiple height-adjustable support legs 25 are fixed at intervals at the bottom of the frame 1. A movable base plate 23 is also movably mounted on the bottom of the frame 1, and multiple rollers 24 are provided on the movable base plate 23. This arrangement allows for convenient operation of the various components of the cutting machine via the control box 10 located on one side of the frame 1, and also provides greater safety by allowing operation away from the work platform 2. The movable base plate 23 with multiple rollers 24 at the bottom of the frame 1 facilitates easy movement of the equipment and adjustment of its position, making it very convenient to use.

[0041] The embodiments of the present utility model have been described above with reference to the accompanying drawings. However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims. All of these forms are within the scope of protection of the present utility model.
