Description

Technical Field

[0001] This invention is an integrated laser cutting and welding device, belonging to the field of laser processing technology. Background Technology

[0002] Currently, the processing of tubular workpieces in existing technologies is usually completed using separate cutting and welding equipment. That is, the tubular workpiece is first cut to a fixed length and shape using laser cutting equipment, and then the cut workpiece is transferred to laser welding equipment for welding. The two processes require manual or additional transfer mechanisms to move the workpiece, which not only increases the processing cycle of the workpiece, but also easily leads to a decrease in the subsequent welding accuracy due to positioning deviations during the transfer process. At the same time, the operation of separate equipment requires separate operators, the equipment occupies a large area, and the overall processing cost is high.

[0003] Furthermore, existing methods for feeding tubular workpieces mostly involve manual feeding or simple feeding structures. Manual feeding is labor-intensive, inefficient, and poses operational safety hazards. Simple feeding structures can only achieve a single feeding action and cannot be linked with cutting and welding processes. In terms of workpiece clamping, traditional clamping mechanisms mostly use external clamping. For thin-walled tubular workpieces, excessive clamping force can easily cause workpiece deformation, affecting processing quality. A few internal support clamping mechanisms have complex structural designs, low internal support adjustment accuracy, and cannot adapt to tubular workpieces of different diameters, resulting in poor versatility.

[0004] Furthermore, in existing laser processing equipment, the switching between cutting and welding functions is mostly done by replacing the laser head or adjusting the equipment position. The switching process is cumbersome and time-consuming, which further reduces the overall processing efficiency.

[0005] In view of the shortcomings of the existing technologies, there is an urgent need to develop a laser processing device that can realize the integrated operation of automatic feeding, precise clamping, cutting and welding of tubular workpieces, and the linkage control of each process, so as to solve the problems of low efficiency of split processing, easy deformation of clamping, and cumbersome process switching, and meet the needs of industrial production for efficient and high-precision processing of tubular workpieces.

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an integrated laser cutting and welding device.

An inner support assembly is also mounted on the sliding seats.

[0012] Furthermore, the inner support assembly includes an inner support rod fixed in the middle of the chuck. The outer surface of the inner support rod has two sets of mounting grooves. An outer support plate and an inner support plate are movably connected to the inner sides of the mounting grooves, respectively.

[0013] Furthermore, the inner support rod is slidably connected to an inclined seat. Each of the four sides of the inclined seat is provided with a guide inclined surface that is adapted to the inclined block. A track groove is provided in the middle of the guide inclined surface. A guide groove is provided on each side of the track groove. The other end of the movable plate is slidably connected to the guide grooves on both sides.

[0016] Furthermore, the cutting laser generator is equipped with an optical attenuator and a laser rangefinder on its side.

[0017] Furthermore, an electrical control box is provided on the top of the frame, and a synchronization controller and a power supply are provided inside the electrical control box.

The control panel, the power supply, the cutting laser generator, the welding laser generator, the optical attenuator, and the laser ranging head are all electrically connected to the synchronization controller.

[0018] The beneficial effects of this invention are:

[0019] This invention, through the design of a workpiece clamping mechanism, allows the tubular workpiece to be rotated during cutting or welding. The rotation of the gear set driven by the rotary motor drives the chuck and the inner support rod, thereby rotating the tubular workpiece and achieving a complete cutting or welding action. During the cutting or welding process, the tubular workpiece will not wobble because the inner walls at both ends are fixed by the two sets of inner support plates, thus improving the stability of cutting or welding.

[0020] This invention, through the design of the internal support assembly, after the tubular workpiece moves to the workpiece clamping mechanism, activates cylinders six and seven to push the sliding seat and moving block towards both ends of the tubular workpiece, causing the internal support rod on the sliding seat to penetrate into the interior of the tubular workpiece. Then, cylinder eight is activated, which presses and pushes the upper connecting part of the movable component. The movable component rotates around the end of the horizontal plate as an axis, and the lower connecting part of the movable component presses and pushes the horizontal bar to move on the guide plate. The end of the horizontal bar presses the push block and the connecting rod. The movement of the connecting rod within the internal support rod causes the inclined seat to move synchronously. The inclined seat, through the guide inclined surface and the movable plate, presses and pushes the inclined block and the outer support plate to perform an outward rotational action within the mounting groove. While the outer support plate rotates and expands outward, it slides and presses the protrusion through the movable groove, causing the inner support plate to perform an outward action synchronously. Thus, the end of the inner support plate presses and supports the inner wall of the tubular workpiece.

[0021] The present invention, through the design of the welding mechanism, allows the position of the mounting frame to be adjusted by the horizontal slide rail 1 and the vertical slide rail 1 during use. Then, the cutting laser generator or welding laser generator on the mounting frame is activated to cut or weld the tubular workpiece. The position of the cutting laser generator and the welding laser generator can be switched by adjusting the motor.

[0022] The present invention, through the design of the feeding mechanism, places several tubular workpieces into the guiding channel during use. The tubular workpieces are distributed in an L-shape along the guiding channel. Then, the control box starts the third cylinder, which pushes the push rod. The push rod laterally penetrates the bottom of the guiding channel, thereby pushing the tubular workpieces through the discharge port to two horizontally positioned receiving plates, thus realizing the discharge action of the tubular workpieces.

[0023] This invention, through the design of the feeding assembly, after the tubular workpiece is discharged, moves the moving seat and side plate by four cylinders, so that the tubular workpiece on the support plate is moved laterally between the inner support rod and the ejector pin, thereby realizing the feeding action. Then, after the inner support assembly fixes the tubular workpiece internally, in order to avoid the support plate affecting the cutting action of the tubular workpiece, the support plate and the tubular workpiece can be separated.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figures 1-18This invention provides a laser cutting and welding integrated device technical solution, including a frame 1. A discharge port 2 is provided at the top of the frame 1. Workpiece clamping mechanisms are provided at the top of the frame 1 and on both sides of the discharge port 2. A welding mechanism and a feeding mechanism are respectively provided on both sides of the workpiece clamping mechanism. The feeding mechanism includes a fixing plate 13 located on one side of the discharge port 2. A material box 14 is fixedly installed on the fixing plate 13. A guide channel 15 is provided at the top of the material box 14. Several tubular workpieces 18 are placed in the guide channel 15. Grooves 16 are provided on the inner wall of the bends of the guide channel 15. Through holes and discharge ports 17 that cooperate with the tubular workpieces 18 are respectively provided on both sides of the bottom of the guide channel 15. A cylinder 19 and a feeding motor 2 are fixed on one side of the fixing plate 13. 0. The output end of the feeding motor 20 is equipped with a feeding rod 22. The feeding rod 22 is movably inserted into the groove 16 and connected and fixed to several feeding blades 23. The telescopic end of the cylinder 3 19 is connected to a push rod 21. The push rod 21 passes through the through hole into the guide channel 15. The top of the fixing plate 13 is provided with a feeding assembly on the side away from the cylinder 3 19. In use, several tubular workpieces 18 are placed into the guide channel 15. The tubular workpieces 18 are distributed in an L-shape along the guide channel 15. Then, the cylinder 3 19 is started through the electrical control box. The cylinder 3 19 pushes the push rod 21. The push rod 21 is inserted laterally into the bottom of the guide channel 15, thereby pushing the tubular workpieces 18 to move laterally through the discharge port 17 onto two horizontally positioned receiving plates 28, thus realizing the discharge action of the tubular workpieces 18.

[0046] See Figure 9The feeding assembly includes a cylinder 24 fixed to the top of the fixed plate 13. The output end of the cylinder 24 is connected to a movable seat 25, which is slidably connected to the top of the fixed plate 13. A side plate 26 is fixed to one side of the outer surface of the movable seat 25. A support seat 27 is provided on the top side of the side plate 26. Two material bearing plates 28 are rotatably connected to the support seat 27. The material bearing plates 28 are located on the side of the discharge port 17. A movable plate 30 is slidably connected to the other side of the top of the side plate 26. An inclined top plate 31 is fixed to one side of the movable plate 30. The tail of the material bearing plate 28 is pressed together with the inclined top plate 31. The other side of the movable plate 30 is connected to the output end of a cylinder 29, which is fixed to the side of the movable seat 25. After the tubular workpiece 18 is discharged, the movable seat 24 is pushed by the cylinder 24. 5 and side plate 26 move, so that the tubular workpiece 18 on the support plate 28 moves laterally between the inner support rod 40 and the ejector pin 35, thereby realizing the feeding action. After the inner support assembly fixes the tubular workpiece 18, in order to avoid the support plate 28 affecting the cutting action of the tubular workpiece 18, it is necessary to separate the support plate 28 from the tubular workpiece 18. That is, the cylinder 5 29 drives the moving plate 30 to move away from the support plate 28, so that the tail end of the support plate 28 changes from contacting the bottom straight section of the inclined top plate 31 to contacting the bottom inclined section of the inclined top plate 31, thereby changing the support plate 28 from a horizontal state to an inclined state, so that the support plate 28 can move away from the tubular workpiece 18. The bottom of the inclined top plate 31 is provided with a bottom straight section and a bottom inclined section. The bottom inclined section and the bottom straight section are connected. The bottom straight section is located away from the bottom inclined section.

[0047] See Figure 10The workpiece clamping mechanism includes sliding seats 36 and transverse slide rails 32 mounted on both sides of the top of the frame 1. A moving block 34 is slidably connected to the transverse slide rail 32. A cylinder 33 connected to the moving block 34 is fixed to the side of the transverse slide rail 32. A ejector pin 35 is fixed to the side of the moving block 34. The sliding seats 36 are slidably connected to the top of the frame 1. The side of the sliding seats 36 is connected to the output end of a cylinder 37, which is fixed to the top of the frame 1. A chuck 38 is mounted in the middle of the sliding seats 36, and a large tooth is mounted at the tail of the chuck 38. The large gear meshes with a small gear on its side, and the small gear is connected to the output end of the rotary motor 39. The rotary motor 39 is mounted on the sliding seat 36, and an inner support assembly is also mounted on the sliding seat 36. When the tubular workpiece 18 is being cut or welded, the rotary motor 39 can drive the gear set to rotate, thereby driving the chuck 38 and the inner support rod 40 to rotate, thus driving the rotation of the tubular workpiece 18 and realizing the complete cutting or welding action. During the cutting or welding process, the tubular workpiece 18 will not wobble because the inner walls at both ends are fixed by the two sets of inner support plates 43, thus improving the stability of cutting or welding.

[0048] See Figure 11-18The inner support assembly includes an inner support rod 40 fixed in the middle of the chuck 38. Two sets of mounting grooves 41 are formed on the outer surface of the inner support rod 40. An outer support plate 42 and an inner support plate 43 are movably connected to the inner sides of the mounting grooves 41, respectively. A mating groove 44, adapted to the inner support plate 43, is formed at the middle of one end of the outer support plate 42. Movable grooves 45 are formed on the inner walls of both sides of the mating groove 44. Protrusions are fixed on both sides of the outer surface of the inner support plate 43, and these protrusions are slidably connected within the movable grooves 45. An inclined block 46 is fixed to the bottom of the outer support plate 42. The bottom of the surface block 46 has a through groove, and several mounting supports are provided on the inner wall of the through groove. The top of the movable plate 47 is rotatably connected to the mounting supports. The specific installation position can be adjusted according to the size of the workpiece being processed or the usage requirements, thereby adjusting the inner support angle of the inner support plate 43. The inner support rod 40 is slidably connected to an inclined surface seat 48. Each of the four sides of the inclined surface seat 48 has a guide inclined surface 49 that matches the inclined surface block 46. A track groove 50 is provided in the middle of the guide inclined surface 49. A track groove 50 is provided on each of the two sides inside the track groove 50. The guide groove 51 is provided, and the other end of the movable plate 47 is slidably connected to the guide groove 51 on both sides. A connecting rod 52 is fixed in the middle of the inclined seat 48. One end of the connecting rod 52 extends movably through the outer side of the inner support rod 40 and is connected and fixed to the push block 53. The inner support assembly also includes a cylinder 54 and a horizontal plate 55 fixed on the sliding seat 36. A movable part 56 is movably connected to the end of the horizontal plate 55. The two ends of the movable part 56 are respectively provided with an upper connecting part 57 and a lower connecting part 58. A guide plate 59 is fixed to the bottom of the horizontal plate 55. The guide plate 59 is horizontally connected to the guide plate 59. A crossbar 60 is slidably connected. The end of the crossbar 60 and the side output end of the cylinder 54 are slidably connected to the upper connecting part 57 and the lower connecting part 58 respectively via shafts. Both the upper connecting part 57 and the lower connecting part 58 are provided with sliding grooves adapted to the shafts. The other end of the crossbar 60 is provided with a bearing groove 61. The push block 53 is rotatably connected in the bearing groove 61 and connected to the bearing. Through the design of the bearing groove 61 and the bearing, the pushing action of the crossbar 60 on the push block 53 and the rotation action of the push block 53 can be adapted to each other.After the tubular workpiece 18 moves to the workpiece clamping mechanism, cylinders 6 (33) and 7 (37) are activated to push the sliding seat 36 and the moving block 34 towards both ends of the tubular workpiece 18, causing the inner support rod 40 on the sliding seat 36 to penetrate into the interior of the tubular workpiece 18. Then, cylinder 8 (54) is activated, pressing and pushing the upper connecting part 57 of the movable part 56. The movable part 56 rotates about the end of the horizontal plate 55 as its axis, and the lower connecting part 58 of the movable part 56 presses and pushes the crossbar 60 to move on the guide plate 59. The end of rod 60 presses against the push block 53 and connecting rod 52. The movement of connecting rod 52 within the inner support rod 40 causes the inclined seat 48 to move synchronously. The inclined seat 48, through the guide inclined surface 49 and movable plate 47, presses against and pushes the inclined block 46 and outer support plate 42 to rotate outward within the mounting groove 41. Simultaneously, the outer support plate 42, while rotating outward, slides through the movable groove 45 to press against the protrusion, causing the inner support plate 43 to expand outward synchronously. This, in turn, provides pressure support to the inner wall of the tubular workpiece 18 through the end of the inner support plate 43.

[0049] See Figure 4 The welding mechanism includes a support frame 3, with a horizontal slide rail 4 mounted on the top of the support frame 3. A vertical slide rail 6 is slidably connected to the horizontal slide rail 4. A cylinder 5 connected to the vertical slide rail 6 is fixed to the side of the horizontal slide rail 4. A mounting plate 8 is slidably connected to the vertical slide rail 6. A cylinder 7 connected to the mounting plate 8 is fixed to the side of the vertical slide rail 6. A U-shaped frame is mounted on the mounting plate 8. A mounting frame 10 is rotatably connected to the U-shaped frame. An adjusting motor 9 connected to the mounting frame 10 is fixed to the side of the U-shaped frame. A cutting laser generator 11 and a welding laser generator 12 are respectively mounted on both sides of the mounting frame 10. The mounting frame 1 is equipped with an optical attenuator and a laser rangefinder. An electrical control box is located on the top of the frame 1, containing a synchronization controller and a power supply. A control panel is located on the outside of the control box. The control panel, the power supply, the cutting laser generator 11, the welding laser generator 12, the optical attenuator, and the laser rangefinder are all electrically connected to the synchronization controller. During use, the position of the mounting frame 10 can be adjusted using the horizontal slide rail 4 and the vertical slide rail 6. Then, the cutting laser generator 11 or the welding laser generator 12 on the mounting frame 10 can be activated to cut or weld the tubular workpiece 18. The position of the cutting laser generator 11 and the welding laser generator 12 can be switched using the adjusting motor 9.

[0050] The circuits and electronic components, modules and controllers, or the heat dissipation holes and maintenance doors in the space of the adapted electrical equipment are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this application does not involve improvements to software and methods or heat dissipation and maintenance.

[0051] In use, several tubular workpieces 18 are placed into the guide channel 15, arranged in an L-shape along the guide channel 15. Then, cylinder three 19 is activated via the electrical control box, pushing the push rod 21 laterally into the bottom of the guide channel 15, thereby pushing the tubular workpieces 18 through the discharge port 17 onto two horizontally positioned receiving plates 28. Subsequently, cylinder four 24 pushes the moving seat 25 and side plate 26 to move, causing the tubular workpieces 18 on the receiving plate 28 to move laterally between the inner support rod 40 and the ejector pin 35. Then, cylinders six 33 and seven 3... 7. Both push the sliding seat 36 and the moving block 34 to move towards both ends of the tubular workpiece 18, so that the inner support rod 40 on the sliding seat 36 penetrates into the interior of the tubular workpiece 18. Then, the cylinder 8 54 is activated, and the cylinder 8 54 presses and pushes the upper connecting part 57 of the movable part 56. The movable part 56 rotates about the end of the horizontal plate 55 as the axis point. The lower connecting part 58 of the movable part 56 will press and push the horizontal bar 60 to move on the guide plate 59. The end of the horizontal bar 60 will press the push block 53 and the connecting rod 52. The movement of the connecting rod 52 in the inner support rod 40 will drive the inclined seat 48 to move synchronously. The inclined seat 48 will move through the guide inclined The surface 49 and the movable plate 47 press and push the inclined block 46 and the outer support plate 42 to rotate outward within the mounting groove 41. While rotating outward, the outer support plate 42 slides and presses the protrusion through the movable groove 45, causing the inner support plate 43 to simultaneously expand outward. This, in turn, compresses and supports the inner wall of the tubular workpiece 18 through the end of the inner support plate 43. At this time, the tubular workpiece 18 is fixed by the two sets of inner support plates 43 on the inner support rod 40. Then, the welding mechanism adjusts the position of the cutting laser generator 11 or the welding laser generator 12 to perform the welding action. When it is necessary to switch between cutting and welding actions, the mechanism is activated. The adjustable motor 9 drives the mounting bracket 10 supporting the cutting laser generator 11 or the welding laser generator 12 to rotate, thereby realizing the position exchange between the cutting laser generator 11 and the welding laser generator 12, thus achieving the switching of cutting and welding actions. During cutting or welding, the rotary motor 39 drives the gear set to rotate, which in turn drives the chuck 38 and the inner support rod 40 to rotate, thereby driving the rotation of the tubular workpiece 18 to achieve a complete cutting action. During the cutting process, the tubular workpiece 18 will not shake because the inner walls at both ends are fixed by the two sets of inner support plates 43, thus achieving stable cutting or welding.
