Description

Technical Field

[0001] This invention relates to the field of laser processing equipment technology, specifically to an automated processing device for aluminum alloy furniture production. Background Technology

[0002] In the production and manufacturing of metal furniture, aluminum alloy square tubes are widely used in the frame structure of products such as tables, chairs, shelves and cabinets due to their advantages such as light weight, corrosion resistance and beautiful appearance. As a raw material, aluminum alloy square tubes usually need to go through processes such as drilling, cutting and welding before the assembly of various parts can be completed.

[0003] In existing technologies, drilling operations for aluminum alloy square tubes mostly use mechanical drill bits or punches. However, since aluminum alloy square tubes are mostly thin-walled hollow structures, the axial pressure applied by the drill bit during mechanical drilling can easily cause the tube wall to be dented. This is especially true for square tubes with thinner walls, where the denting deformation is more severe, directly affecting the flatness of the furniture's appearance and the structural strength.

[0004] More importantly, with the widespread application of intelligent manufacturing equipment, some companies have begun to try using laser processing to replace mechanical drilling. Although laser drilling is a non-contact processing method that can alleviate the denting problem caused by mechanical drilling force to some extent, for thin-walled aluminum alloy square tubes, which have a low melting point and fast heat conduction speed, the local high temperature at the moment of laser piercing will cause the material around the hole to lose rigidity instantly, resulting in a "thermal softening collapse" phenomenon, which causes the edge of the hole to be recessed inward or the hole shape to be out of round.

[0005] The aforementioned problems not only affect assembly accuracy but also significantly increase the difficulty of subsequent intelligent welding system calibration and production costs. They also expose the inadequacy of current metal welding equipment in dealing with high-precision aluminum alloy components. Summary of the Invention

[0006] The purpose of this invention is to provide an automated processing device for aluminum alloy furniture production, in order to solve the problem mentioned in the background art that aluminum alloy has a low melting point and a fast heat conduction speed. During laser perforation, the local high temperature will cause the material around the hole to lose rigidity instantly, resulting in a "thermal softening and collapse" phenomenon, which leads to the hole edge being concave inward or the hole shape being out of round.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An automated processing device for aluminum alloy furniture production includes a frame on which metal welding equipment and an intelligent welding system are mounted.

[0010] Preferably, a first groove is provided on the inner wall of the second block, a gear is rotatably installed in the first groove, and a first rack is fixedly installed on the opposite surface of the magnetic block and the first block, and the gear meshes with both first racks at the same time.

[0011] Preferably, a guide rod is fixedly installed on the base plate, and guide holes are provided on both the first block and the pad. The guide rod passes through the guide holes. The pad has an extension on the side near the first block, and a first spring is sleeved on the guide rod. The two ends of the first spring abut against the opposite surfaces of the extension and the first block, respectively.

[0012] Preferably, the adjustment device includes a motor and a back plate mounted on a frame. The output end of the motor is connected to a lead screw via a coupling. A nut seat is fixedly provided on the back plate, and the nut seat is threadedly engaged with the lead screw. At least one first slide rod is also fixedly connected to the frame. The back plate is slidably fitted onto the first slide rod. The metal welding equipment is mounted on the back plate.

[0013] Preferably, a slide rail is fixedly installed on the frame, the support platform is slidably installed on the slide rail, extension rods are fixedly installed on both sides of the support platform, a pressure rod is fixedly installed on the back plate, a connecting seat is fixedly installed on the frame, and a swing arm is rotatably installed in the connecting seat. One end of the swing arm is rotatably connected to the extension rod, and the other end forms a free end that fits against the pressure rod.

[0014] Preferably, the clamping assembly includes a fixed ring rotatably mounted on a support platform, an inner ring coaxially disposed within the fixed ring, and a first clamping part and a second clamping part fixedly mounted on the side of the inner ring opposite to the fixed ring, the first clamping part and the second clamping part being spaced apart circumferentially; each of the first clamping part and the second clamping part includes a mounting base, a connecting rod slidably mounted within the mounting base, a sliding pin fixedly mounted on the connecting rod, and a second sliding groove adapted to the sliding pin on the mounting base; an adjusting groove is provided on the inner ring, a second sliding rod slidably mounted within the adjusting groove, an adjusting ring fixedly mounted at the end of the second sliding rod outside the adjusting groove, an arc-shaped groove being provided on the adjusting ring, and the end of the sliding pin away from the connecting rod simultaneously extending into and confining within the arc-shaped groove; wherein, at least one of the second sliding rods is a locking bolt.

[0015] Preferably, the first clamping part further includes a hollow rod fitted inside the connecting rod. A flexible tube is connected to the end of the connecting rod away from the hollow rod. A first clamping head is fixedly installed at the end of the hollow rod away from the connecting rod. A nozzle is provided on the side of the first clamping head facing the fixing ring. The nozzle communicates with the inner cavity of the hollow rod. A valve core is installed inside the hollow rod. A valve seat is installed inside the first clamping head. The valve core and the valve seat cooperate to control the opening and closing of the nozzle. A second spring is sleeved on the hollow rod. The two ends of the second spring are fixed to the connecting rod and the first clamping head, respectively.

[0016] Preferably, the second clamping part further includes a second clamping head fixed to the connecting rod, and a contact band is tensioned inside the second clamping head.

[0017] Preferably, the outer wall of the fixed ring is provided with transmission teeth, the inner wall of the fixed ring is provided with a ratchet groove, the outer wall of the inner ring is provided with a mounting groove, and an elastic pawl is hinged in the mounting groove.

A second rack is fixedly installed on the frame, and the second rack is meshed with the transmission teeth.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. By utilizing the magnetic attraction between the magnetic block and the magnetic plate, and through the transmission linkage of gears and racks, the axial locking of the inner lining support block and the radial lifting of the pad block are realized simultaneously. This provides high-rigidity bending support from the opposite side inside the pipe and rapidly dissipates heat through the heat-absorbing medium inside the pad block. This solves the problems of "thermal softening collapse" and hole out-of-roundness caused by fast heat conduction and low melting point in the laser processing of thin-walled aluminum alloy square tubes. It significantly improves the drilling accuracy and cross-sectional quality, and makes the device as a whole possess the process adaptability required by metal welding equipment.

[0020] 2. By utilizing the mechanical coupling relationship between the square tube's sinking amount and the clamping assembly, the opening and closing states of the valve core and valve seat are automatically controlled by the compression stroke of the second spring, realizing the zoned switching of the protective gas path at the upper and lower clamping points: the nozzle is opened only in the upper processing area to spray protective gas, while the lower nozzle automatically closes as the clamping force increases. No additional sensors or solenoid valves are required. While ensuring good atmosphere protection in the laser welding and drilling areas, it effectively avoids gas waste and interference with the internal support structure of the tube, significantly reducing system complexity and energy consumption, and improving the operational stability and reliability of the intelligent welding system.

[0039] 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.

[0040] Example: This invention provides a technical solution: such as Figure 1 - Figure 11The diagram illustrates an automated processing device for aluminum alloy furniture production, comprising a frame 10 on which a metal welding device 30 and an intelligent welding system 40 are mounted. The metal welding device 30 uses a fiber laser and can be used for both laser drilling of aluminum alloy furniture components and subsequent laser welding operations. The intelligent welding system 40 is electrically connected to the metal welding device 30 and has a built-in weld seam recognition and process parameter database. It can automatically adjust the laser power, pulse frequency, and focus position according to different process requirements, achieving seamless switching between drilling and welding modes. The system supports online feedback adjustment to ensure precise and controllable energy input during processing. An adjustment device 20 is also provided on the frame 10, on which the metal welding device 30 is mounted to adjust the processing position to adapt to the processing needs of aluminum alloy furniture components of different specifications.

[0041] A support platform 11 is slidably mounted on the frame 10. Clamping components 50 are provided on both sides of the support platform 11 for positioning and clamping the aluminum alloy square tube. A support rod 12 is slidably mounted on one side of the frame 10. An inner lining support block 60 is fixed to one end of the support rod 12 facing the support platform 11. The inner lining support block 60 can extend into the interior of the aluminum alloy square tube to support the laser action area from the inner wall.

[0042] like Figure 5 and Figure 6 As shown, the inner lining support block 60 includes a first block 61, on which a slag collection groove 62 is provided for collecting molten spatter generated during laser drilling. A pad 63 is provided on the first block 61, and the pad 63 has a through hole 64 coaxial with the slag collection groove 62 to avoid the laser beam. The pad 63 is filled with a heat-absorbing medium, such as a copper-based or graphite-based high thermal conductivity material, which quickly absorbs and dissipates heat during laser processing to suppress heat accumulation in thin-walled areas.

[0043] In actual operation, this device is a complete set of intelligent manufacturing equipment. First, the support platform 11 and the clamping assembly 50 complete the positioning and clamping of the aluminum alloy square tube. Then, the support rod 12 drives the inner lining support block 60 to be inserted into the square tube, so that the pad block 63 is in close contact with the inner wall of the hole to be processed.

[0044] During the drilling stage, the intelligent welding system 40 controls the metal welding equipment 30 to output a high peak power pulsed laser according to the preset process parameters. The beam passes through the through hole 64 and acts on the pipe wall. Since the spacer 63 is filled with a heat-absorbing medium, it can quickly remove the heat from the laser action area and prevent the aluminum alloy from "thermal softening collapse" due to its low melting point and fast heat conduction. This ensures that the hole shape is round and the hole opening is free of depression. At the same time, the slag collection tank 62 can effectively collect molten slag and avoid splashing and contaminating the inner wall of the pipe.

[0045] Reference Figure 5 and Figure 6The inner lining support block 60 also includes a second block 65 and a base plate 66. The second block 65 is symmetrically arranged with the first block 61 as the center. A magnetic block 651 is installed inside the second block 65 by a tension spring 652. A magnetic plate 13 is fixedly installed on the frame 10. A slot 111 for the magnetic plate 13 to pass through is opened on the support platform 11.

[0046] The base plate 66 is fixedly connected to the bottom of the second block 65. The base plate 66 has a notch 661 that communicates with the interior of the second block 65. The magnetic block 651 can be exposed through the notch 661 and magnetically attracted to the magnetic plate 13, thereby achieving radial fixation of the inner lining support block 60 during the processing and restricting axial movement by the friction force generated by radial tightening.

[0047] Structurally, the first block 61 is used to face the laser processing area and provide thermal support, while the second block 65 is used to form lateral support inside the tube and enhance the bending stiffness of the tube. The two work together to improve the overall stability of the thin-walled aluminum alloy square tube during the laser processing.

[0048] Furthermore, a first groove 653 is provided on the inner wall of the second block 65, and a gear 654 is rotatably installed in the first groove 653. A first rack 601 is fixedly installed on the opposite surface of the magnetic block 651 and the first block 61. The gear 654 meshes with the two first racks 601 at the same time, so that when the magnetic block 651 moves, the first block 61 is synchronously driven to move in opposite directions or away from each other through the transmission of the gear 654.

[0049] A guide rod 662 is fixedly installed on the base plate 66. Guide holes 602 are opened on the first block 61 and the pad block 63. The guide rod 662 passes through the guide hole 602 to provide linear guidance for the lifting and lowering movement of the first block 61 and the pad block 63.

[0050] The pad 63 has an extension 621 on the side near the first block 61. A first spring 622 is sleeved on the guide rod 662. The two ends of the first spring 622 abut against the opposite surfaces of the extension 621 and the first block 61, respectively, to provide flexible buffering and adaptive clamping force during laser processing.

[0051] The support platform 11 moves the aluminum alloy square tube to the processing station. At this time, the magnetic plate 13 is inserted into the slot 111 of the support platform 11. The magnetic block 651 slides down through the notch 661 under the action of magnetic force, fixing the square tube on the support platform 11. At the same time, through the transmission cooperation of the first rack 601 and the gear 654, the first block 61 is synchronously driven to rise towards the inner wall of the tube, so that the pad 63 fits against the inner top surface of the square tube. The first spring 622 is used to provide flexible buffer and adaptive clamping force. During the laser drilling process, the intelligent welding system 40 controls the metal welding equipment 30 to output high peak pulse laser. The heat-absorbing medium inside the pad 63 quickly conducts away the heat, thereby effectively suppressing "thermal softening collapse".

[0052] Reference Figure 1 and Figure 4 The adjusting device 20 includes a motor 21 and a back plate 22 mounted on the frame 10. The output end of the motor 21 is connected to a lead screw 23 via a coupling. A nut seat 221 is fixedly mounted on the back plate 22. The nut seat 221 is threadedly engaged with the lead screw 23. At least one first slide rod 24 is also fixedly connected to the frame 10. The back plate 22 is slidably mounted on the first slide rod 24. The metal welding equipment 30 is mounted on the back plate 22.

[0053] Furthermore, a slide rail 14 is fixedly installed on the frame 10, a support platform 11 is slidably installed on the slide rail 14, extension rods 112 are fixedly installed on both sides of the support platform 11, a pressure rod 222 is fixedly installed on the back plate 22, a connecting seat 15 is fixedly installed on the frame 10, and a swing arm 16 is rotatably installed inside the connecting seat 15. One end of the swing arm 16 is rotatably connected to the extension rod 112, and the other end forms a free end that fits against the pressure rod 222.

[0054] When the motor 21 starts, it drives the back plate 22 to descend along the first slide bar 24 through the cooperation of the lead screw 23 and the nut seat 221. The metal welding equipment 30 installed on the back plate 22 descends to the processing height in sync.

[0055] As the back plate 22 descends, the pressure rod 222 descends accordingly, pressing the swing arm 16 to rotate around the connecting seat 15. The other end of the swing arm 16 drives the support platform 11 to move horizontally along the slide rail 14 through the extension rod 112, so that the aluminum alloy square tube gradually enters the processing area, realizing the synchronous and coordinated movement of the processing end and the workpiece.

[0056] Reference Figure 7 - Figure 9 The clamping assembly 50 includes a fixed ring 51 rotatably mounted on the support platform 11. An inner ring 52 is coaxially arranged inside the fixed ring 51. A first clamping part 53 and a second clamping part 54 are fixedly installed on the side of the inner ring 52 opposite to the fixed ring 51. The first clamping part 53 and the second clamping part 54 are arranged circumferentially at intervals for multi-point rigid clamping of the aluminum alloy square tube.

[0057] Both the first clamping part 53 and the second clamping part 54 include a mounting base 501. A connecting rod 502 is slidably mounted in the mounting base 501. A sliding pin 503 is fixedly mounted on the connecting rod 502. A second sliding groove 504 adapted to the sliding pin 503 is provided on the mounting base 501 to guide the linear movement of the connecting rod 502.

[0058] An adjustment groove 521 is provided on the inner ring 52. A second slide rod 522 is slidably installed in the adjustment groove 521. An adjustment ring 523 is fixedly installed at one end of the second slide rod 522 outside the adjustment groove 521. An arc-shaped groove 505 is provided on the adjustment ring 523. The end of the sliding pin 503 away from the connecting rod 502 extends into and is confined in the arc-shaped groove 505. When the adjustment ring 523 rotates, the arc-shaped groove 505 drives the connecting rod 502 to slide along the second slide groove 504 through the sliding pin 503, thereby realizing the clamping or releasing action.

[0059] It should be noted that at least one second slide rod 522 is a locking bolt. When the adjusting ring 523 is rotated to the required position, the second slide rod 522 is fixed in the adjusting groove 521 by tightening the locking bolt to prevent the clamping force from loosening during the processing.

[0060] The operator places the aluminum alloy square tube on the support platform 11, with the tube inserted into the center hole of the inner ring 52. The outer wall is located between the first clamping part 53 and the second clamping part 54. The operator rotates the adjusting ring 523, and the arc groove 505 drives the connecting rod 502 to slide along the second sliding groove 504 to one side of the square tube through the sliding pin 503. This causes the first clamping part 53 and the second clamping part 54 to tighten synchronously, applying clamping force to the aluminum alloy square tube from multiple points around the circumference. After clamping is completed, the second sliding rod 522, which serves as a locking bolt, is tightened to lock the adjusting ring 523, ensuring a stable clamping state during processing.

[0061] Reference Figure 10 The first clamping part 53 also includes a hollow rod 531 fitted inside the connecting rod 502. A hose 506 is connected to the end of the connecting rod 502 away from the hollow rod 531. The hose 506 is connected to an external protective gas source. A first clamping head 532 is fixedly installed at the end of the hollow rod 531 away from the connecting rod 502. A nozzle 533 is provided on the side of the first clamping head 532 facing the fixing ring 51. The nozzle 533 communicates with the inner cavity of the hollow rod 531 and is used to deliver protective gas to the surface of the aluminum alloy square tube.

[0062] A valve core 534 is installed inside the hollow rod 531, and a valve seat 535 is installed inside the first clamping head 532. The valve core 534 and the valve seat 535 cooperate to control the opening and closing of the nozzle 533. In the initial clamping state, the valve core 534 and the valve seat 535 remain separated to protect the air passage. A second spring 536 is sleeved on the hollow rod 531. The two ends of the second spring 536 are fixed to the connecting rod 502 and the first clamping head 532 respectively, and are used to provide flexible cushioning during clamping.

[0063] During processing, as the magnetic block 651 slides downward through the notch 661 under the action of magnetic force, the downward movement of the magnetic block 651 will generate a downward component force on the aluminum alloy square tube. This downward movement is absorbed by the second spring 536 below the support platform 11. The second spring 536 is compressed and, under the reaction force, pushes the first clamping head 532 to further press against the outer wall of the square tube. As the first clamping head 532 moves, the valve core 534 inside the hollow rod 531 is inserted into the first clamping head 532 under the action of axial force. In the valve seat 535 inside 32, since the first clamping part 53 is distributed vertically on the cross-section of the square tube, in the lower first clamping part 53, the valve core 534 and the valve seat 535 are closed, the nozzle 533 is blocked, and the protective gas path is cut off. In the upper first clamping part 53, the valve core 534 and the valve seat 535 are still separated, the nozzle 533 remains open, and the protective gas continues to be sprayed outward to the processing area through the hose 506 and the hollow rod 531, effectively inhibiting the high-temperature oxidation of the aluminum alloy.

[0064] Reference Figure 11 The second clamping part 54 also includes a second clamping head 541 fixed to the connecting rod 502. The second clamping head 541 has a contact band 542 tensioned inside, which is used to directly contact the surface of the square tube during the clamping process. When the aluminum alloy square tube sinks due to the magnetic attraction of the magnetic block 651 during the processing, the contact band 542 can slide slightly with the square tube, thereby reducing the static friction between the square tube and the second clamping head 541 and avoiding surface scratches or stress concentration caused by hard friction.

[0065] Reference Figure 9 The outer wall of the fixed ring 51 is provided with transmission teeth 511, the inner wall of the fixed ring 51 is provided with a ratchet groove 512, and the outer wall of the inner ring 52 is provided with a mounting groove 524. An elastic pawl 525 is hinged in the mounting groove 524. The elastic pawl 525 is engaged with the ratchet groove 512. The elastic pawl 525 always has a tendency to engage with the ratchet groove 512 due to its own elasticity, so as to limit the unidirectional rotation of the inner ring 52 relative to the fixed ring 51.

[0066] A second rack 17 is fixedly installed on the frame 10 on one side of the slide rail 14. The second rack 17 is arranged along the moving direction of the support platform 11 and is meshed with the transmission teeth 511.

[0067] When the support platform 11 moves along the slide rail 14 under the drive of the swing arm 16, the second rack 17 drives the fixed ring 51 and the inner ring 52 to rotate synchronously through meshing with the transmission teeth 511, thereby realizing the flipping of the workpiece.

[0068] Working principle:

[0069] During operation, the aluminum alloy square tube is placed in the two inner rings 52, and the inner lining support block 60 is located inside the aluminum alloy square tube. Through the transmission of the adjusting ring 523, the arc groove 505 and the sliding pin 503, the first clamping part 53 and the second clamping part 54 are driven to tighten synchronously, and the aluminum alloy square tube is rigidly clamped from multiple points in the circumference.

[0070] The adjustment device 20 drives the metal welding equipment 30 to descend, so that the fiber laser is always at the optimal processing height. At the same time, through the linkage of the swing arm 16 and the pressure rod 222, the support table 11 is driven to feed horizontally. Under the control of the intelligent welding system 40, the metal welding equipment 30 automatically switches between drilling and welding modes according to the process requirements, and dynamically adjusts the laser power, pulse frequency and focus position.

[0071] During the feeding process of the support platform 11, the magnetic plate 13 is gradually inserted into the slot 111 on the support platform 11. The magnetic block 651 slides downward under the magnetic force of the magnetic plate 13 and is attracted to the magnetic plate 13. The downward movement of the magnetic block 651 will generate a downward component force on the aluminum alloy square tube, fixing the aluminum alloy square tube on the support platform 11 between the magnetic block 651 and the magnetic plate 13. At the same time, the downward displacement of the magnetic block 651 is driven by the meshing transmission of the first rack 601 and the gear 654, synchronously driving the first block 61 to rise upward, so that the pad 63 is tightly attached to the inner wall of the square tube, providing rigid support for the back inner wall of the laser action area from the inside of the tube.

[0072] During the aforementioned magnetic fixation process, the aluminum alloy square tube experiences a slight downward movement due to the force component, which is absorbed by the second spring 536 below the support platform 11. As the second spring 536 compresses, the first clamping head 532 displaces relative to the connecting rod 502, causing the valve core 534 inside the hollow rod 531 to insert into the valve seat 535. Since the first clamping parts 53 are distributed vertically on the cross-section of the square tube, the valve core 534 in the lower clamping part 53 closes with the valve seat 535, the nozzle 533 is blocked, and the protective gas path is cut off; while in the upper clamping part 53, the valve core 534 remains separated from the valve seat 535, the nozzle 533 remains open, and the protective gas continues to be sprayed outward to the processing area through the hose 506 and the hollow rod 531. This mechanically linked gas path switching ensures effective protection of the processing area while avoiding gas waste.

[0073] In addition, when the support platform 11 retracts, the second rack 17 meshes with the transmission teeth 511, and the elastic pawl 525 cooperates with the ratchet groove 512 to restrict unidirectional rotation, so that the aluminum alloy square tube can be rotated 180° during the retraction process, which can complete the processing of the opposite two sides of the tube.
