Description

Technical Field

[0001] This application relates to the field of laser cutting, and more specifically, to a laser cutting machine. Background Technology

[0002] Laser cutting machines work by irradiating the surface of a workpiece with a laser beam, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas is used to blow away the molten or vaporized metal. As the relative position of the laser beam and the workpiece moves, a kerf is eventually formed on the workpiece, thus achieving the purpose of cutting.

[0003] For example, Chinese Patent Publication No. CN108453378A discloses the following technical solution: a laser cutting machine, relating to the field of laser cutting technology. This laser cutting device, which facilitates positioning, includes a support plate. Two support legs are fixedly connected to both ends of the bottom surface of the support plate. A slide rail is fixedly installed at the center of the top surface of the support plate. A slider is fitted inside the slide rail at its center. A workpiece groove plate is fixedly connected to the top surface of the slider. A transverse groove is formed on the front surface of the slider. A bolt is provided at the center of the front surface of the slide rail. This laser cutting device, which facilitates positioning, allows the workpiece to be positioned first through the cooperation of the slide rail and the slider. Then, by activating a cylinder, the laser cutting device can easily adjust its height. This allows the laser cutting device to be quickly positioned at any height, further improving the efficiency of workpiece processing.

[0004] However, the workpiece slot is located at the lower end of the laser cutting device, so the space at the upper end is relatively narrow, which may make it difficult to pick up and put down the workpiece in the slot, and there is a risk of personnel bumping into it. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a laser cutting machine that solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this application provides a laser cutting machine, including a worktable with a laser cutting machine mounted on its upper end. A rotating column is rotatably connected to the upper end of the worktable via bearings. A slide rail is fixedly fitted onto the outer wall of the rotating column, and a guide groove is formed on the outer wall of the rotating column. A hydraulic chamber is located at the upper end of the worktable. Hydraulic rods A and B are slidably connected to the two ports of the hydraulic chamber, respectively. A connecting plate is fixedly connected to the other end of hydraulic rod B. A connecting rod is fixedly connected to the bottom of the connecting plate, and a sliding shaft is fixedly connected to the outer wall of the connecting rod. Lubrication components are assembled at both ends of the connecting plate. The lubrication components utilize a hose pump and a delivery hose to drive the delivery of lubricating oil via a rotating rod, ensuring that the lubricating oil is accurately applied to key areas, such as the connection between the mounting shaft and the mounting groove, ensuring smooth operation of the mechanical moving parts. A protective component is assembled on the back of the connecting plate, which can effectively surround the laser cutting area, blocking flying debris, high-temperature sparks, and harmful fumes generated during the cutting process, thus protecting the safety of the operator.

[0007] Preferably, a C-shaped plate is fixedly connected to the upper end of the workbench, a cylinder is fixedly connected to the top of the C-shaped plate, a mounting plate is fixedly connected to the output end of the cylinder, the laser cutting machine is fixedly connected to the bottom of the mounting plate, the bottom of the hydraulic rod A is fixedly connected to the mounting plate, and the hydraulic chamber is fixedly connected to the C-shaped plate.

[0008] Preferably, the end of the sliding shaft away from the connecting rod is slidably connected inside the guide groove.

[0009] Preferably, a workpiece groove plate is slidably connected to the outer wall of the slide rail, and a bolt is provided at the center of the front side of the workpiece groove plate.

[0010] Preferably, the protective component includes mounting slots on both sides of the mounting plate, a mounting shaft rotatably connected inside the mounting slots, a connecting block A fixedly sleeved on the outer wall of the mounting shaft, a protective plate fixedly connected to the bottom of the connecting block A, one end of the mounting shaft movably passing through the mounting plate and fixedly connected to a toothed plate, a connecting block B fixedly connected to the outer wall of the connecting plate, and a toothed plate A fixedly connected to the outer wall of the connecting block B.

[0011] Preferably, the toothed plate A is located on the side of gear A and meshes with gear A.

[0012] Preferably, the lubrication assembly includes a mounting block, which is fixedly connected to the inner side of the C-shaped plate. A hose pump is fixedly connected to the other side of the mounting block. A liquid storage tank is fixedly connected to the top of the C-shaped plate. A delivery hose is fixedly connected to the bottom of the liquid storage tank. The other end of the delivery hose passes through the hose pump and is fixedly connected to an oil outlet pipe. A rotating rod is fixedly connected to the rotating shaft inside the hose pump. A gear B is fixedly connected to the other end of the rotating rod. Toothed plates B are fixedly connected to both ends of the connecting plate.

[0013] Preferably, the gear B is located on the side of the toothed plate B and meshes with it.

[0014] The advantages of this application are:

[0015] (1) This application uses a cylinder to drive the mounting plate and the laser cutting machine to move up and down, enabling the laser cutting machine to perform cutting tasks at an appropriate height. In particular, when the upper end of the worktable rotates the rotating column and slide rail via a hydraulic system, the workpiece slot can also be adjusted to a suitable position as needed. This design ensures that the workpiece loading and unloading operations are more convenient. The rotation design of the rotating column and its connected slide rail allows the workpiece slot to be easily transferred from the horizontal direction to the vertical direction, making it easier for the operator to accurately place the workpiece to be cut in the slot. This rotation function can reduce the difficulty of manually handling workpieces, save time, and improve work efficiency.

[0016] (2) By setting up protective components, this application can effectively surround the laser cutting area, block the flying debris, high-temperature sparks and harmful fumes generated during the cutting process, and protect the safety of operators.

[0017] (3) This application uses a lubrication assembly to deliver lubricating oil via a hose pump and a delivery hose, and drives the delivery of lubricating oil through a rotating rod, ensuring that the lubricating oil can be accurately applied to key parts, such as the connection between the mounting shaft and the mounting groove, and ensuring the smooth operation of the mechanical moving parts.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Example 1: Please refer to Figure 1-7A laser cutting machine includes a worktable 1, which serves as the basic support platform for the device, supporting the laser cutting machine 2, the slide rail system 32, and hydraulic components. It must have high rigidity and shock resistance. The laser cutting machine 2 is installed on the upper end of the worktable 1. The laser cutting machine 2 is the core component and is responsible for performing the actual cutting work. The high-power laser beam precisely cuts the workpiece into a specified shape. It integrates a power adjustment module to adapt to the cutting needs of different materials such as metal and plastic, and is equipped with an automatic focusing lens calibration function. The upper end of the worktable 1 is rotatably connected to a rotating column 31 via a bearing. The outer wall of the rotating column 31 is fixedly fitted with a slide rail 32. The surface of the slide rail 32 is hard chrome plated to improve wear resistance. The outer wall of the rotating column 31 is provided with a guide groove 33. The spiral groove design converts the vertical movement of the slide shaft 39 into the rotational movement of the rotating column 31. The upper end of the worktable 1 is provided with a hydraulic chamber 34. The two ports of the hydraulic chamber 34 are respectively slidably connected to hydraulic rods A35 and B36. The other end of the hydraulic rod B36 is fixedly connected to a connecting plate 37. The bottom of the connecting plate 37 is fixedly connected to a connecting rod 38. The outer wall of the connecting rod 38 is fixedly connected to a slide shaft 39. The two ends of the connecting plate 37 are equipped with lubrication components 5, and the back of the connecting plate 37 is equipped with a protective component 4. A U-shaped plate 7 is fixedly connected to the upper end of the worktable 1. A cylinder 6 is fixedly connected to the top of the U-shaped plate 7. A mounting plate 8 is fixedly connected to the output end of the cylinder 6. The laser cutter 2 is fixedly connected to the bottom of the mounting plate 8. The bottom of the hydraulic rod A35 is fixedly connected to the mounting plate 8. The hydraulic chamber 34 is fixedly connected to the U-shaped plate 7. The end of the sliding shaft 39 away from the connecting rod 38 is slidably connected to the inside of the guide groove 33. A workpiece groove plate 9 is slidably connected to the outer wall of the slide rail 32. A bolt 10 is provided at the center of the front of the workpiece groove plate 9 for manual locking to prevent displacement during laser cutting.

[0035] In operation, before the laser cutting machine 2 performs laser cutting, the cylinder 6 moves the mounting plate 8 to a higher position. At this time, the rotating column 31 causes the slide rail 32 to rotate to a position perpendicular to the worktable 1. This facilitates placing the workpiece to be cut inside the workpiece slot plate 9. After moving the workpiece slot plate 9 to a suitable position on the outer wall of the slide rail 32, it is fixed with bolts 10. Then, the cutting operation can begin. First, the cylinder 6 moves the mounting plate 8 and the laser cutting machine 2 at its bottom downwards. When the mounting plate 8 descends, it causes the hydraulic rod A35 at its upper end to descend as well. Then, the hydraulic rod B36, which is also located inside the other port of the hydraulic chamber 34, will move upward, thereby causing the connecting plate 37 at the bottom of the hydraulic rod B36 to rise. The connecting rod 38 at the bottom of the connecting plate 37 will also rise at the same time, and the sliding shaft 39 will also rise. During the rise, the sliding shaft 39 will slide inside the guide groove 33 on the outer wall of the rotating column 31, thereby causing the rotating column 31 to rotate inward. The rotating column 31 will then drive the slide rail 32 to rotate inward. When the slide rail 32 rotates to be parallel to the worktable 1, the laser cutting machine 2 will also move to the appropriate height.

[0036] Example 2: Please refer to Figure 1-6 The protective component 4 includes mounting slots 41 on both sides of the mounting plate 8. A mounting shaft 42 is rotatably connected inside the mounting slots 41. A connecting block A43 is fixedly sleeved on the outer wall of the mounting shaft 42. A protective plate 44, made of transparent explosion-proof material (such as polycarbonate), is fixedly connected to the bottom of the connecting block A43. When closed, it surrounds the laser cutting area and blocks flying debris. One end of the mounting shaft 42 movably passes through the mounting plate 8 and is fixedly connected to a toothed plate 45. A connecting block B46 is fixedly connected to the outer wall of the connecting plate 37, and a toothed plate A47 is fixedly connected to the outer wall of the connecting block B46. The toothed plate A47 is located on the side of the gear A45 and meshes with the gear A45.

[0037] In use, when the mounting plate 8 begins to descend, the mounting shaft 42 on its side and the gear A45 at one end of the mounting shaft 42 also descend synchronously. This movement is due to the rigid connection between the mounting plate 8 and the mounting shaft 42, so the vertical movement of the mounting plate 8 is directly transmitted to the mounting shaft 42. Simultaneously, the connecting plate 37 moves upward under the drive of the hydraulic system; this reverse movement is achieved by the rise of the hydraulic rod B36. The rise of the connecting plate 37 drives the toothed plate A47 to rise via the connecting block B46 fixedly connected to its outer wall. Since the toothed plate A47 and the gear A45 are meshed, the upward movement of the toothed plate A47 is converted into the rotational movement of the gear A45. Specifically, the linear rise of the toothed plate A47 drives the gear A45 to rotate. The rotation of the gear A45 further drives the mounting shaft 42 to move inward (i.e., towards the center of the laser cutting machine 2). The inward movement of the mounting shaft 42 is transmitted to the protective plate 44 via the connecting block A43 fixedly connected to its outer wall. Connecting block A43, acting as a support component for protective plate 44, converts the linear motion of mounting shaft 42 into the rotational motion of protective plate 44. Specifically, protective plate 44 rotates inward around the axis of mounting shaft 42, gradually closing to form a protective cover surrounding laser cutting machine 2. The main purpose of this design is to block flying debris, high-temperature sparks, and harmful fumes generated during laser cutting by closing protective plate 44, thereby protecting the operator's safety and preventing external environmental contamination or damage to the optical components of laser cutting machine 2. Protective plate 44 is typically 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.

[0038] 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 U-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 U-shaped plate 7 to store lubricating oil with a capacity of ≥5L. A built-in liquid level sensor provides early warning of low oil levels. A delivery hose 53 is fixedly connected to the bottom of the liquid storage tank 52. The hose has embedded steel wire to enhance its pressure resistance and prevent it from breaking 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 internal drive shaft of the hose pump 54. A gear B56 is fixedly connected to the other end of the rotating rod 55. Gear plates B58 are fixedly connected to both ends of the connecting plate 37. The gear B56 is located on the side of the gear plate B58 and meshes with it.

[0039] In use, when the connecting plate 37 descends, it will drive the toothed plates B58 at both ends to move, and the gear B56 that meshes with it will also rotate, which will drive the rotating rod 55 to rotate. As a result, the rotating rod 55 will rotate towards the output shaft inside the hose pump 54, thereby squeezing the delivery hose 53 inside the hose pump 54. This will squeeze the lubricating oil inside the reservoir 52 through the oil outlet pipe 57 to the connection between the mounting shaft 42 and the mounting groove 41. Because the gear B56 needs to rotate one cycle to achieve lubrication on one side, and the mounting plate 8 will descend to the side of the oil outlet pipe 57 when the gear B56 rotates one cycle, it can ensure that the lubricating oil is applied to the upper end of the rotating rod 55.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
