Description

Technical Field

[0001] This application relates to the technical field of laser cutting machines, and in particular to a plate positioner for a laser cutting machine. Background Technology

[0002] A laser cutting machine uses a laser emitted from a laser source to focus a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

[0003] For example, Chinese utility model patent CN220296175U discloses a plate locator for a laser cutting machine, including a cutting device. A laser device is fixedly connected inside the cutting device, and a positioning mechanism is fixedly connected inside the cutting device. An adjustment mechanism is fixedly connected inside the positioning mechanism. The positioning mechanism includes a positioning plate, which is fixedly connected inside the cutting device. Fixed plates are fixedly connected to both sides of the positioning plate. A connecting plate is movably connected inside the fixed plate, and a threaded rod is fixedly connected to the top of the connecting plate. The adjustment mechanism works in conjunction with the threaded rod. This plate locator for a laser cutting machine, by setting up a positioning mechanism, can effectively fix the plate during processing, preventing the plate from shifting during processing, increasing the stability of the plate during installation, and facilitating the user in fixing the plate.

[0004] Regarding the aforementioned technologies, the inventors believe that current laser cutting machine plate positioners can use a motor to drive the connecting plate downwards to press and position the plate. However, existing positioners are usually designed according to specific plate dimensions, and may not provide effective pressing and positioning when dealing with plates of different sizes, resulting in reduced cutting accuracy and certain limitations.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a sheet metal positioner for a laser cutting machine. (Refer to...) Figure 1-5A plate locator for a laser cutting machine includes a base 1, a laser cutting machine body 4, and two fixed plates 2. A first movable groove 9 is formed in the middle of the upper surface of the base 1. Two sliders 15 are slidably installed inside the first movable groove 9. A connecting frame 5 is fixedly installed on the upper surface of each slider 15. An electric telescopic rod 12 is fixedly installed on the upper surface of the connecting frame 5. A connecting plate 14 is fixedly connected to the output end of the electric telescopic rod 12. The laser cutting machine body 4 is mounted on the base 1 and used for cutting the plate. One side of the fixed plate 2 is fixedly connected to the connecting plate 14. A mounting groove 17 is formed on the lower surface of the fixed plate 2. Two pressure plates 6 are slidably installed inside the mounting groove 17. A driving mechanism for moving the pressure plates 6 is provided on the fixed plate 2. The driving mechanism includes a drive motor 3, which is fixedly connected to the upper surface of the fixed plate 2. Two sets of connecting components 23 provide bidirectional lead screws 19 inside the fixed plate 2. The components, including connecting rods, connecting rings, and bearings, are existing technologies and widely used in society, so they will not be described in detail. The two ends of the bidirectional lead screw 19 are respectively threaded into the interior of the two pressure plates 6. The output end of the drive motor 3 is fixedly connected to the first bevel gear 20. The side wall of the bidirectional lead screw 19 is fitted with a second bevel gear 21 that meshes with the first bevel gear 20. The interior of the base 1 has two second movable grooves 10 on both sides of the first movable groove 9. The two sides of the slider 15 are fixedly connected to guide plates 16 that are slidably disposed inside the second movable grooves 10. The base 1 is provided with multiple sets of limiting components for limiting the guide plates 16. The limiting components include a fixing frame 8 and a threaded rod 22. The fixing frame 8 is in contact with the side wall of the base 1. One end of the threaded rod 22 is rotatably connected to the side wall of the guide plate 16. The other end of the threaded rod 22 is threaded through the side wall of the fixing frame 8. The end of the threaded rod 22 away from the guide plate 16 is fixedly connected to a knob 11.

[0027] The implementation principle of the laser cutting machine plate positioner in this application embodiment is as follows: All electrical components in this application are externally connected to a power supply and control switch during use. In use, the plate to be processed is placed on the base 1. Activating the electric telescopic rod 12 moves the fixed plate 2 downwards via the connecting plate 14. The fixed plate 2 moves the pressure plate 6 downwards, causing the bottom of the fixed plate 2 and pressure plate 6 to fit against the top of the plate, thus clamping and positioning the plate. The laser cutting machine body 4 can then process the plate. For plates of different sizes, rotating the knob 11 rotates the threaded rod 22, which in turn moves the fixed frame 8, ensuring that the vertical surface of the fixed frame 8 is not in contact with the side wall of the base 1. Horizontally moving the fixed frame 8 moves the guide plate 16 and slider 15. The slider 15 moves the fixed plate 2 via the connecting frame 5, allowing the fixed plate 2 to move horizontally on the base 1. This allows adjustment of the distance between the two fixed plates 2 according to the length of the plate. Activating the drive motor 3 drives the first bevel gear 20. The first bevel gear 20 can drive the double-acting screw 19 to rotate via the second bevel gear 21. The double-acting screw 19 can drive the two pressure plates 6 on it to slide inside the fixed plate 2, so as to adjust the length of the pressure plate 6 according to the width of the plate. After the adjustment is completed, the operation of the drive motor 3 is paused, and the fixed frame 8 is reset by rotating the threaded rod 22 in the opposite direction, so that the vertical surface of the fixed frame 8 is in contact with the side wall of the base 1, which can limit the position of the slider 15 and the fixed plate 2, so that the plate can be positioned laterally. During this process, the fixed plate 2 can be moved by moving the fixed frame 8, so that the fixed plate 2 can move horizontally on the base 1, so as to adjust the distance between the two fixed plates 2 according to the length of the plate. The drive motor 3 can drive the pressure plate 6 to slide inside the fixed plate 2, so as to adjust the length of the pressure plate 6 according to the width of the plate, thus making it suitable for plates of different sizes. By rotating the threaded rod 22, the fixed frame 8 can be in contact with the side wall of the base 1, so as to limit the adjusted fixed plate 2, improving the adaptability and practicality of the overall device.

[0028] Reference Figure 1-3 Both sides of the pressure plate 6 are fixedly connected to the limiting plate 7. The inside of the fixed plate 2 is symmetrically provided with limiting grooves 18 that slide with the limiting plate 7. When the pressure plate 6 slides, it can drive the limiting plate 7 to slide in the limiting groove 18. The limiting plate 7 can limit the pressure plate 6, making the pressure plate 6 more stable when sliding.

[0029] Reference Figure 2 Guide rods 13 are symmetrically and slidably installed through the side wall of the connecting frame 5. The bottom end of the guide rods 13 is fixedly connected to the upper surface of the connecting plate 14. The guide rods 13 can improve the stability of the connecting plate 14 when it moves vertically.
