[0002] With the rapid development of the construction industry, aluminum curtain wall panels, as a lightweight, high-strength, and aesthetically pleasing building material, are widely used in the exterior wall decoration of modern buildings. Assembly and welding are crucial steps in the processing and manufacturing of aluminum curtain wall panels.

[0003] Patent document CN118578020A discloses a welding table for assembling aluminum panels for curtain walls. By introducing a guiding mechanism, the placement of aluminum panels becomes more precise and stable, effectively reducing errors and damage caused by improper operation. Secondly, the ingenious design of the clamping mechanism ensures the stability of the aluminum panels during the welding process, improving welding quality and having certain positive significance. However, some aluminum panels require welding at different angles to meet construction requirements.

[0004] The patent document with publication number CN121223236A discloses a partial hot-melt welding device for aluminum panels of curtain walls. It uses plasma arc technology with a climbing mechanism to weld aluminum panels on the exterior of the building structure, which has certain positive significance. However, plasma arc welding requires a relatively strict environment, and direct construction on the exterior wall of the building poses a significant safety hazard. Furthermore, it is not convenient to inspect the welding effect afterward. Summary of the Invention

[0005] The purpose of this application is to provide a welding device for processing aluminum exterior wall panels in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the technical solution of this application is as follows: A welding device for processing aluminum exterior wall panels, comprising: Control panel; Two angle adjustment plates are symmetrically hinged on the operating table; An elastic limiting plate is slidably disposed at one end of the angle adjustment plate that is far apart from each other; it is used to drive the two aluminum plates to be welded to move closer to each other. A self-locking pressure bar is hinged to the elastic limiting plate and is used to press the aluminum plate firmly against the angle adjustment plate.

[0007] Furthermore, two sliding rods are spaced apart along the welding direction on the operating table. The two sliding rods are vertically arranged and have a horizontally mounted shaft on them. The two angle adjustment plates are hinged to the mounted shaft. A lead screw is rotatably provided between the two sliding rods. A nut slider is threaded onto the lead screw. A connecting rod is hinged to the nut slider. The end of the connecting rod away from the nut slider is hinged to the side of the angle adjustment plate facing away from the aluminum plate.

[0008] Furthermore, a baffle is provided on the side of the two angle adjustment plates that are far apart from each other, and a guide rod is slidably passed through the baffle. The elastic limiting plate is provided at the end of the guide rod located above the angle adjustment plate. A spring is provided between the baffle and the elastic limiting plate, and the spring is sleeved on the guide rod.

[0009] Furthermore, the elastic limiting plate is provided with a plurality of mounting grooves spaced apart along the welding direction, and a rod is installed in each of the plurality of mounting grooves, and the self-locking pressure rod is hinged in the mounting rod.

[0010] Furthermore, the angle adjustment plate is provided with a clearance groove corresponding to the mounting groove, and the clearance groove extends through the angle adjustment plate.

[0011] Furthermore, the self-locking lever is an L-shaped lever, comprising a trigger section and a lever section; When one side of the aluminum plate placed on the angle adjustment plate abuts against the trigger end, the self-locking pressure rod rotates, causing the pressure rod segment to move toward the angle adjustment plate.

[0012] Furthermore, the mounting shaft is provided with two rotating shafts, and each rotating shaft has meshing teeth on a section outside the mounting shaft. The two rotating shafts rotate synchronously through the meshing teeth.

[0013] Furthermore, one of the rotating shafts is provided with a first rotation limiting rod at one end, and the other rotating shaft is provided with a second rotation limiting rod at the other end; It also includes two sets of limiting rods. One set of limiting rods has one end clamped to one edge of the aluminum plate and the other end used to abut against the first rotation limiting rod. The other set of limiting rods is clamped to the other opposite edge of another aluminum plate and the other end used to abut against the second rotation limiting rod.

[0014] Furthermore, the operating table includes a support frame, a support plate, an x-axis moving mechanism, a y-axis moving mechanism, and a z-axis moving mechanism; it also includes a plasma arc welding torch, which is mounted on the z-axis moving mechanism.

[0015] Furthermore, the z-axis moving mechanism is provided with a vertical rod, and the vertical rod is provided with an arc-shaped support groove, which is used to support the cable of the plasma arc welding gun.

[0016] The welding equipment for processing aluminum panels for exterior walls disclosed in this application has two angle adjustment plates symmetrically hinged on the operating table. The hinge points can be made of wear-resistant alloy bushings in conjunction with pin-type components to achieve rotation. Addressing the core need in the background technology that "some aluminum panels need to be welded at different angles", it breaks through the limitation of the fixed angle of the traditional welding table. The elastic limiting plate continuously drives the two aluminum panels to be welded to move closer to each other through its own elastic force, eliminating the need for manual alignment. This avoids the docking errors caused by manual operation and improves docking efficiency. Attached Figure Description

[0019] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0020] like Figures 1-13 As shown, a welding device for processing aluminum exterior wall panels includes: Operating platform; As the basic load-bearing structure of the entire welding equipment, the operating platform provides a stable installation benchmark for all subsequent functional components. Its structural design must meet the mechanical strength requirements. It can be made of steel welded to ensure that it does not deform when bearing the weight of the aluminum plate and the forces during the welding process.

[0021] Two angle adjustment plates 33 are symmetrically hinged on the operating table. The hinge points can be made of wear-resistant alloy bushings and pin-type components to achieve rotation. This addresses the core requirement in the background technology that "some aluminum plates 4 need to be welded at different angles", and breaks through the limitation of fixed angle of traditional welding tables.

[0022] The elastic limiting plate 37 is slidably disposed at one end of the angle adjusting plate 33 that is far apart from each other; it is used to drive the two aluminum plates 4 to be welded to move closer to each other; the elastic limiting plate 37 is slidably disposed at one end of the angle adjusting plate 33 that is far apart from each other, and its sliding direction is consistent with the docking direction of the two angle adjusting plates 33. It continuously drives the two aluminum plates 4 to be welded to move closer to each other through its own elastic force, without the need for manual alignment, which avoids docking errors caused by manual operation and improves docking efficiency.

[0023] The self-locking pressure rod 38 is hinged on the elastic limiting plate 37 and is used to press the aluminum plate 4 against the angle adjustment plate 33.

[0024] The self-locking pressure rod 38 is hinged to the elastic limiting plate 37 and can rotate freely around the hinge point. Its function is to firmly press the aluminum plate 4 onto the angle adjustment plate 33, which solves the problem of displacement of the aluminum plate 4 due to vibration or force during the welding process. Compared with the pressing mechanism in the prior art, the self-locking pressure rod 38 can adapt to different tilt angles of the angle adjustment plate 33, ensuring that a stable pressing force can be provided at any welding angle, thereby ensuring the welding quality.

[0025] By setting two angle adjustment plates 33 with adjustable angles, different welding requirements between aluminum plates 4 can be met. At the same time, during the positioning process, after the aluminum plate 4 is placed on the angle adjustment plate 33, under the action of the elastic limiting plate 37, the edge of the aluminum plate 4 will trigger the self-locking pressure rod 38. The stronger the force of the elastic limiting plate 37 on the aluminum plate 4, the stronger the clamping force of the self-locking pressure rod 38 on the aluminum plate 4. When the aluminum plates 4 on the two angle adjustment plates 33 abut against each other, the abutting force of the elastic limiting plate 37 on the aluminum plate 4 is the greatest, and the reaction force of the aluminum plate 4 on the self-locking pressure rod 38 is also the greatest, further making the clamping effect of the self-locking pressure rod 38 on the aluminum plate 4 optimal and ensuring the stability of the welding process.

[0026] Furthermore, two sliding rods 31 are spaced apart along the welding direction on the operating table. The two sliding rods 31 are vertically arranged, and a horizontally placed mounting shaft 32 is provided on the sliding rod 31. Two angle adjustment plates 33 are hinged on the mounting shaft 32. A lead screw 30 is rotatably provided between the two sliding rods 31. A nut slider 300 is threaded on the lead screw 30. A connecting rod 301 is hinged on the nut slider 300. The end of the connecting rod 301 away from the nut slider 300 is hinged to the side of the angle adjustment plate 33 facing away from the aluminum plate 4.

[0027] Two sliding rods 31, spaced apart along the welding direction on the operating table, are fixed to the surface of the operating table by vertical welding. The sliding rods 31 can be made of round steel, and a mounting shaft 32 is set horizontally at their top ends. The mounting shaft 32 is connected to the sliding rods 31.

[0028] The bottom of the two angle adjustment plates 33 is fixed to the mounting shaft 32 by a hinge sleeve, so that the angle adjustment plates 33 can be rotated around the mounting shaft 32; the two sliding rods 31 are connected to the lead screw 30 by a bearing seat, and the lower end of the lead screw 30 can be connected to a hand crank or a drive motor. The nut slider 300 that is fitted on the lead screw 30 is hinged to the back of the angle adjustment plate 33 by a connecting rod 301. The two ends of the connecting rod 301 are connected to the nut slider 300 and the angle adjustment plate 33 by pins respectively.

[0029] The significance of this structure lies in its ability to achieve precise control of the tilt angle of the angle adjustment plate 33 through the high-precision characteristics of the lead screw 30. Compared with manual flip adjustment, it can effectively avoid angle deviation. At the same time, the lead screw 30 has a self-locking characteristic, which can keep the angle stable after adjustment without the need for an additional locking structure. Its effect is to make the adjustment of the welding angle more convenient and precise, adapt to different angle welding requirements, and improve the welding consistency during mass production.

[0030] Furthermore, under the action of the connecting rod 301, the rotation angle of any of the angle adjustment plates 33 is the same, so as to ensure that the gap to be welded after the two aluminum plates 4 are joined is exactly aligned with the welding gun.

[0031] Furthermore, a baffle 36 is provided on the side of the two angle adjustment plates 33 that are far apart from each other. A guide rod 360 is slidably passed through the baffle 36. An elastic limiting plate 37 is provided at the end of the guide rod 360 located above the angle adjustment plate 33. A spring 361 is provided between the baffle 36 and the elastic limiting plate 37. The spring 361 is sleeved on the guide rod.

[0032] A baffle 36 is welded to one side of the two angle adjustment plates 33 that are far apart from each other. The baffle 36 is set perpendicular to the angle adjustment plates 33 to ensure structural strength. A through guide hole is opened on the baffle 36. The guide rod 360 slides through the guide hole. The guide rod 360 and the guide hole adopt a clearance fit to ensure smooth sliding of the guide rod 360. An elastic limiting plate 37 is welded to the end of the guide rod 360 located above the angle adjustment plate 33. The elastic limiting plate 37 can be made of steel plate, and its surface can be provided with anti-slip rubber pads to avoid scratches when in contact with the aluminum plate 4.

[0033] A spring 361 is sleeved on the outside of the guide rod 360 between the baffle 36 and the elastic limiting plate 37. The spring 361 is a compression spring 361, which can push the elastic limiting plate 37 to move toward the docking direction of the angle adjustment plate 33 in its natural state.

[0034] The elastic force of spring 361 provides a continuous pushing force to the elastic limiting plate 37, allowing the two aluminum plates 4 to be welded to automatically approach and fit together after placement, without the need for manual alignment. This simplifies the operation process, improves docking efficiency, and protects the surface quality of the aluminum plates 4, ensuring docking accuracy.

[0035] Furthermore, the elastic limiting plate 37 is provided with a plurality of mounting grooves 370 at intervals along the welding direction, and rods 371 are installed in each of the plurality of mounting grooves 370, with self-locking pressure rods 38 hinged in the mounting rods 371.

[0036] Multiple mounting slots 370 are spaced apart on the elastic limiting plate 37 along the welding direction. The number of mounting slots 370 can be set according to the length requirements of the welded aluminum plate 4. The mounting rod 371 is fixed laterally in the mounting slot 370 and serves as a carrier to support the rotation of the self-locking pressure rod 38. The mounting rod 371 can be set as a whole, that is, it passes through multiple mounting slots 370 as a whole.

[0037] The self-locking pressure rod 38 is hinged to the mounting rod 371 through a hinge hole. The mounting groove 370 provides an installation position and a clearance position for the self-locking pressure rod 38, ensuring that the self-locking pressure rod 38 can rotate fully under the action of the aluminum plate 4 to press the aluminum plate 4.

[0038] Furthermore, the angle adjustment plate 33 is provided with a clearance groove 330 corresponding to the mounting groove 370, and the clearance groove 330 is provided through the angle adjustment plate 33.

[0039] A clearance groove 330 is provided on the angle adjustment plate 33 at the position corresponding to the mounting groove 370. The clearance groove 330 runs through the upper and lower surfaces of the angle adjustment plate 33. Its width is greater than the diameter of the self-locking pressure rod 38, and its length is greater than the rotation stroke of the self-locking pressure rod 38, so as to avoid interference between the self-locking pressure rod 38 and the angle adjustment plate 33. This ensures that the self-locking pressure rod 38 is not blocked by the angle adjustment plate 33 during the rotation and pressing process, and ensures that the angle adjustment function and the pressing function are implemented in a coordinated manner without interfering with each other, thereby improving the overall smoothness of the equipment operation.

[0040] Furthermore, the self-locking lever 38 is an L-shaped lever, including a trigger section 381 and a lever section 380; When one side of the aluminum plate 4 placed on the angle adjustment plate 33 comes into contact with the starting end, the self-locking pressure rod 38 rotates, causing the pressure rod section 380 to move toward the angle adjustment plate 33.

[0041] The self-locking lever 38 is designed as an L-shaped lever and is made of one-piece molded steel to ensure structural strength. The included angle between its trigger section 381 and lever section 380 can be set according to actual clamping requirements, but it is always an acute angle.

[0042] When the aluminum plate 4 is placed on the angle adjustment plate 33 and moved in the docking direction, one side of the aluminum plate 4 will naturally abut against the trigger section 381. The thrust of the aluminum plate 4 drives the self-locking pressure rod 38 to rotate around the mounting rod 371, causing the pressure rod section 380 to move towards the angle adjustment plate 33 and press against the surface of the aluminum plate 4. The core advantage of this self-locking structure is that it realizes the automated operation of "placing and pressing", without the need for additional locking steps, simplifying the operation process. At the same time, it uses the position of the aluminum plate 4 itself to trigger the pressing, ensuring the timeliness and accuracy of the pressing action. Its effect is to improve operation efficiency and reduce manual intervention. Meanwhile, the setting of the elastic rubber pad can prevent the aluminum plate 4 from deforming due to excessive pressing force, ensuring the processing quality of the aluminum plate 4.

[0043] When the slope of the angle adjustment plate 33 is not such that the aluminum plate 4 slides down and triggers the self-locking rod 38, the subsequent elastic limiting plate 37 will also force the trigger section 381 of the self-locking rod 38 to abut against the aluminum plate 4.

[0044] Furthermore, the mounting shaft 32 is provided with two rotating shafts 34, and each rotating shaft 34 is provided with meshing teeth 35 on a section outside the mounting shaft 32. The two rotating shafts 34 rotate synchronously through the meshing teeth 35.

[0045] Two rotating shafts 34 are rotatably arranged inside the mounting shaft 32. The section of the rotating shaft 34 located outside the mounting shaft 32 is machined with meshing teeth 35. The meshing teeth 35 of the two rotating shafts 34 mesh with each other to ensure synchronous rotation.

[0046] The meshing teeth 35 are designed to meet the coordinated adjustment requirements of the two angle adjustment plates 33, and to prevent misalignment of the aluminum plates 4 caused by excessive rotation or angle deviation of one side of the angle adjustment plate 33. The mechanical transmission of the meshing teeth 35 enables the synchronous rotation of the two rotating shafts 34, ensuring that the two aluminum plates 4 can be connected at the joint of the two angle adjustment plates 33 at the same time, thus reducing welding defects.

[0047] Furthermore, one of the rotating shafts 34 is provided with a first rotation limiting rod at one end, and the other rotating shaft 34 is provided with a second rotation limiting rod at the other end. It also includes two sets of limiting rods 41. One set of limiting rods 41 has one end clamped to one edge of the aluminum plate 4 and the other end used to abut against the first rotation limiting rod. The other set of limiting rods 41 is clamped to the other opposite edge of another aluminum plate 4 and the other end used to abut against the second rotation limiting rod.

[0048] A first rotation limit rod is welded to one end of one of the rotating shafts 34, and a second rotation limit rod is welded to the other end of the other rotating shaft 34. Both the first and second rotation limit rods are set perpendicular to the rotating shafts 34.

[0049] One end of the limiting rod 41 is provided with a clamping part, which can be firmly clamped to the edge of the aluminum plate 4, and the other end is a flat abutting surface, which is used to abut against the first rotation limiting rod or the second rotation limiting rod.

[0050] The clamping mechanism can be achieved by tightening the fixed clamping plate, the movable clamping plate, and the bolts and nuts.

[0051] The main function of the limit rod 41 is to stop it from being stopped by the limit rod located in the outer area of ​​the angle adjustment plate 33, so as to ensure that the two aluminum plates 4 rise at the same speed, and further ensure that the two aluminum plates 4 reach the welding area at the same time.

[0052] During the upward movement of aluminum plate 4, limit rod 41 pushes the corresponding limit rod to rotate. Since aluminum plate 4 on both angle adjustment plates 33 is pushed upward by their respective elastic limit plates 37, it can always drive limit rod 41 to push the limit rod.

[0053] The first limiting rod 39 and the second limiting rod 390 can ensure that one aluminum plate 4 cannot reach the area to be welded before the other aluminum plate 4.

[0054] Furthermore, the operating table includes a support frame 1, a support plate 14, an x-axis moving mechanism 1010, a y-axis moving mechanism 1111, and a z-axis moving mechanism 1212; it also includes a plasma arc welding torch 2, which is mounted on the z-axis moving mechanism 1212.

[0055] The operating table includes a support frame 1 and a support plate 14. The support frame 1 is made of square steel welded together to ensure overall stability. The support plate 14 is laid on top of the support frame 1 to support components such as the angle adjustment plate 33. The x-axis moving mechanism 10, y-axis moving mechanism 11, and z-axis moving mechanism 12 can all adopt a linear module structure. The linear module has the characteristics of high transmission accuracy and smooth operation. The x-axis moving mechanism 10 is installed on the support frame 1, the y-axis moving mechanism 11 is installed on the slider of the x-axis moving mechanism 10, and the z-axis moving mechanism 12 is installed on the slider of the y-axis moving mechanism 11 to realize three-dimensional movement. The plasma arc welding gun 2 is fixed on the slider of the z-axis moving mechanism 12 by a clamp. The model of the plasma arc welding gun 2 can be selected according to the welding requirements.

[0056] The support frame 1, x-axis moving mechanism 10, y-axis moving mechanism 11 and z-axis moving mechanism 12 are very common in three-axis moving mechanisms and are existing technologies. Their specific structures and working principles will not be described in detail in this embodiment. In addition to the above-mentioned linear module, other similar structures can also be used to achieve the movement of each of the three.

[0057] This application addresses the problem in the background technology of "safety hazards in exterior wall construction and inconvenience in inspecting welding results" by transferring welding operations to an indoor operating table, eliminating the safety risks of high-altitude operations on exterior walls. At the same time, the three-dimensional moving mechanism can drive the plasma arc welding torch 2 to move along any welding path, adapting to welding needs at different angles and positions. After welding is completed, the welding effect can be directly inspected on the operating table without the need for high-altitude operations. The effect is to improve the safety and convenience of welding operations. In addition, the high-precision transmission of the three-dimensional moving mechanism can improve the welding quality.

[0058] Furthermore, the z-axis moving mechanism 1212 is provided with a vertical pole, and the vertical pole is provided with an arc-shaped support groove 13, which is used to support the cable of the plasma arc welding gun 2.

[0059] A vertical rod is welded to the slider of the Z-axis moving mechanism 12. The vertical rod is made of round steel, and its top is machined with an arc-shaped support groove 13. The curvature of the arc-shaped support groove 13 is adapted to the outer diameter of the cable of the plasma arc welding gun 2. Anti-slip rubber pads can be attached inside the support groove to increase the friction with the cable. The purpose of this structure is to solve the problem of tangling and pulling caused by the excessive length of the plasma arc welding gun 2 cable. Since the plasma arc welding gun 2 needs to move up and down with the Z-axis moving mechanism 12, if the cable is placed randomly, it will entangle with the equipment parts or be damaged by pulling. The arc-shaped support groove 13 can support and guide the cable, so that the cable is arranged in an orderly manner when the welding gun moves, avoiding tangling and excessive pulling. Its effect is to protect the cable, extend its service life, and at the same time ensure that the welding gun moves smoothly without being interfered with by the cable, thus ensuring the continuity of the welding process.

[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
