[0025] Embodiment 1: Please refer to Figure 1-7, a laser cutting machine, including a workbench 1, which serves as the basic support platform of the device, carrying the laser cutting machine 2, the slide rail 32 system and the hydraulic components, and must have high rigidity and seismic resistance. The upper end of the workbench 1 is provided with a laser cutting machine 2; the laser cutting machine 2 is the core component responsible for the actual cutting work. Through a high-power laser beam, the workpiece to be processed is accurately cut into a specified shape, integrating a power adjustment module to adapt to the cutting requirements of different materials such as metals and plastics, and equipped with an automatic calibration function for the focusing lens. The upper end of the workbench 1 is rotatably connected to a rotating column 31 through a bearing. The outer wall of the rotating column 31 is fixedly sleeved with a slide rail 32, and the surface of the slide rail 32 is treated with hard chromium plating to improve wear resistance. The outer wall of the rotating column 31 is provided with a guiding groove 33, which is designed as a spiral groove to convert the vertical movement of the sliding shaft 39 into the rotational movement of the rotating column 31. The upper end of the workbench 1 is provided with a hydraulic chamber 34. The two ports of the hydraulic chamber 34 are respectively slidably connected with a hydraulic rod A 35 and a hydraulic rod B 36. The other end of the hydraulic rod B 36 is fixedly connected with a connecting plate 37. The bottom of the connecting plate 37 is fixedly connected with a connecting rod 38. The outer wall of the connecting rod 38 is fixedly connected with a sliding shaft 39. Lubricating components 5 are assembled at both ends of the connecting plate 37, and a protective component 4 is assembled on the back of the connecting plate 37. The upper end of the workbench 1 is fixedly connected with an L-shaped plate 7. The top of the L-shaped plate 7 is fixedly connected with a cylinder 6. The output end of the cylinder 6 is fixedly connected with a mounting plate 8. The laser cutting machine 2 is fixedly connected to the bottom of the mounting plate 8. The bottom of the hydraulic rod A 35 is fixedly connected with the mounting plate 8. The hydraulic chamber is fixedly connected with the L-shaped plate. The hydraulic chamber 34 is fixedly connected with the L-shaped plate 7. The end of the sliding shaft 39 away from the connecting rod 38 is slidably connected inside the guiding groove 33. The outer wall of the slide rail 32 is slidably connected with a workpiece groove plate 9. A bolt 10 is arranged at the center of the front surface of the workpiece groove plate 9 to manually lock and fix the workpiece groove plate 9 to prevent displacement during laser cutting.

[0026] During use, before the laser cutting machine 2 performs laser cutting operations, the air cylinder 6 will drive the mounting plate 8 to a higher position. At this time, the rotating column 31 will rotate the slide rail 32 to a state perpendicular to the workbench 1. At this time, it is convenient to place the workpiece to be cut inside the workpiece groove plate 9. Then move the workpiece groove plate 9 on the outer wall of the slide rail 32 to a suitable position and fix it with bolts 10. At this time, cutting operations can be carried out. First, the air cylinder 6 will drive the mounting plate 8 and the laser cutting machine 2 at its bottom to descend. When the mounting plate 8 descends, it will drive the hydraulic rod A 35 at its upper end to descend. Then, the hydraulic rod B 36 located at the other port inside the hydraulic chamber 34 will move upward accordingly, thereby driving the connecting plate 37 at the bottom of the hydraulic rod B 36 to rise. Then, the connecting rod 38 at the bottom of the connecting plate 37 will also rise at any time, and the sliding shaft 39 will also rise accordingly. During the rising process of the sliding shaft 39, it will slide inside the guiding groove 33 on the outer wall of the rotating column 31, thereby causing the rotating column 31 to rotate inward. Furthermore, the rotating column 31 will drive the slide rail 32 to rotate inward. When the slide rail 32 rotates to be parallel to the workbench 1, the laser cutting machine 2 will also move to a suitable height.

[0027] Embodiment 2: Please refer to Figure 1-6 , the protection component 4 includes mounting grooves 41 opened on both sides of the mounting plate 8. A mounting shaft 42 is rotatably connected inside the mounting grooves 41. A connecting block A 43 is fixedly sleeved on the outer wall of the mounting shaft 42. A protection plate 44 is fixedly connected to the bottom of the connecting block A 43. A transparent explosion-proof material (such as polycarbonate), which surrounds the laser cutting area when closed to block flying debris. One end of the mounting shaft 42 movably penetrates through the mounting plate 8 and is fixedly connected to a toothed plate 45. A connecting block B 46 is fixedly connected to the outer wall of the connecting plate 37. A toothed plate A 47 is fixedly connected to the outer wall of the connecting block B 46. The toothed plate A 47 is located on the side of the gear A 45 and meshes with the gear A 45.

[0028] When in use, when the mounting plate 8 starts to descend, the mounting shaft 42 on its side and the gear A45 at one end of the mounting shaft 42 will also descend synchronously. This movement is due to the fact that the mounting plate 8 and the mounting shaft 42 are fixed by a rigid connection, so the vertical movement of the mounting plate 8 will be directly transmitted to the mounting shaft 42. At the same time, the connecting plate 37 will move upward under the drive of the hydraulic system, and this reverse movement is achieved by the rise of the hydraulic rod B36. The rise of the connecting plate 37 will drive the tooth plate A47 to rise through the connecting block B46 fixedly connected to its outer wall. Since the tooth plate A47 and the gear A45 are connected by meshing, the rising movement of the tooth plate A47 will be converted into the rotational movement of the gear A45. Specifically, the linear rise of the tooth plate A47 will drive the gear A45 to rotate. The rotation of the gear A45 will further drive the mounting shaft 42 to move inward (i.e., toward the center direction of the laser cutting machine 2). The inward movement of the mounting shaft 42 will be transmitted to the protective plate 44 through the connecting block A43 fixedly connected to its outer wall. The connecting block A43, as a supporting component of the protective plate 44, converts the linear motion of the mounting shaft 42 into the rotational motion of the protective plate 44. Specifically, the protective plate 44 rotates inward around the axis of the mounting shaft 42, gradually closes, and finally forms a protective cover surrounding the laser cutting machine 2. The main purpose of this design is to block the flying debris, high-temperature sparks and harmful smoke generated during the laser cutting process by closing the protective plate 44 when the laser cutting machine 2 is performing laser cutting operations, thereby protecting the safety of the operator and preventing the external environment from causing pollution or damage to the optical components of the laser cutting machine 2. The protective plate 44 is usually made of transparent high-strength materials (such as polycarbonate or explosion-proof glass) so that the operator can observe the cutting process without opening the protective cover.

[0029] Example 3: Please refer to Figure 1-8 The lubrication assembly 5 includes a mounting block 51, which is fixedly connected to the inner side of the 匚-shaped plate 7. A hose pump 54 is fixedly connected to the other side of the mounting block 51. A liquid storage tank 52 is fixedly connected to the top of the 匚-shaped plate 7 to store lubricating oil with a capacity of ≥5L. A built-in liquid level sensor is used to warn of oil shortage. A delivery hose 53 is fixedly connected to the bottom of the liquid storage tank 52. The hose has a steel wire embedded in it to enhance the pressure resistance and avoid rupture during pumping. The other end of the delivery hose 53 passes through the hose pump 54 and is fixedly connected to an oil outlet pipe 57. A rotating rod 55 is fixedly connected to the transmission shaft inside the hose pump 54. A gear B56 is fixedly connected to the other end of the rotating rod 55. A toothed plate B58 is fixedly connected to both ends of the connecting plate 37. The gear B56 is located on the side of the toothed plate B58 and meshes with it.

[0030] During use, when the connecting plate 37 descends, it will drive the toothed plates B58 at both ends to move, and then the gear B56 engaged with them will also rotate accordingly. As a result, the rotating rod 55 will be driven to rotate, so that the rotating rod 55 will rotate towards the output shaft inside the hose pump 54. Thus, the inside of the hose pump 54 will squeeze the conveying hose 53, and then the lubricating oil inside the liquid storage tank 52 can be squeezed through the oil outlet pipe 57 to the connection between the mounting shaft 42 and the mounting groove 41. Since the gear B56 needs to move one cycle to achieve the lubrication effect on one side, when the gear B56 rotates one cycle, the mounting plate 8 will descend to the side of the oil outlet pipe 57. Therefore, it can ensure that the lubricating oil is applied to the upper end of the rotating rod 55.

[0031] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
