Description

Technical Field

[0001] This invention relates to the field of aluminum plate welding technology, and in particular to a welding fixture for exterior aluminum wall panels. Background Technology

[0002] In the field of modern architectural decoration, aluminum exterior wall panels are widely used in the facade decoration of various buildings such as shopping malls, hotels, airports, and theaters due to their advantages of being lightweight, high-strength, weather-resistant, durable, aesthetically pleasing, and recyclable. In particular, irregularly shaped aluminum panels, through sheet metal processing and CNC bending, are made into irregular geometric shapes such as curved surfaces, arcs, and waves, which can meet the personalized and artistic design needs of buildings and have become one of the preferred materials for high-end exterior wall decoration.

[0003] During the production of irregularly shaped aluminum plates, since there are no uniform standard specifications for irregularly shaped aluminum plates, the existing tooling is difficult to clamp and fix irregular aluminum plates when welding them. Moreover, the clamping method is prone to uneven force on the aluminum plate during fixation, resulting in elastic deformation or permanent deformation, which in turn causes misalignment and warping of the weld after welding, affecting the flatness and structural stability of the aluminum plate.

[0004] Therefore, this application proposes a welding fixture for external wall aluminum panels that facilitates clamping irregularly shaped aluminum panels. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a welding fixture for aluminum exterior wall panels.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A welding fixture for aluminum exterior wall panels includes welding components mounted on the surface of a frame and fixture components for fixing the aluminum panels. The tooling assembly includes a negative pressure assembly for adsorbing and fixing aluminum plates. The negative pressure assembly includes a base plate fixed to the surface of the frame and a top plate fixed to the upper surface of the base plate. The top plate surface is arrayed with multiple suction cups, which are mounted on the top plate surface through mounting holes. The tooling assembly also includes a positioning component for positioning the aluminum plate, the positioning component including a positioning rod for positioning the height of the aluminum plate and two positioning angle plates for positioning the position of the aluminum plate.

[0007] In some embodiments, the welding assembly includes a welding torch and a gantry for moving the welding torch in multiple degrees of freedom. The welding torch rotates on the surface of the lifting frame, and a rotary joint is rotatably mounted on the top of the welding torch. The rotary joint is fixed to the top of the lifting frame.

[0008] In some embodiments, a sealing assembly for sealing the mounting hole is provided inside the mounting hole. The sealing assembly includes a sealing ring fixed to the inner wall of the mounting hole and a sealing head that slides vertically inside the mounting hole. The sealing head abuts against the surface of the sealing ring by a first spring.

[0009] In some embodiments, a top ring is fixed to the bottom of the suction cup, the top ring is used to push the sealing head to separate from the sealing ring, the suction cup is threaded to the inside of the mounting hole through the top ring, and the surface of the top ring is provided with multiple through grooves.

[0010] In some embodiments, a plurality of water bladders for cooling the suction cup are fixed on the upper surface of the top plate. The water bladders are annular and the plurality of water bladders are connected by a plurality of first connecting pipes.

[0011] In some embodiments, there are two sets of water bladders, which are connected by a second connecting pipe, and both sets of water bladders are connected to a constant pressure tank via a hose.

[0012] In some embodiments, the positioning rod array is disposed on the upper surface of the top plate, and the positioning rod is threadedly connected to the upper surface of the top plate.

[0013] In some embodiments, the two positioning angle plates are located at opposite corners of the base plate, and the positioning angle plates are fixed to the upper surface of the base plate.

[0014] In some embodiments, the positioning assembly further includes a support assembly for positioning the crossbeam. The support assembly includes a fixing frame that rotates on the side of the base plate and a support block fixed to the end of the fixing frame. The fixing frame is L-shaped, and the support block has a positioning groove on the side facing the top plate.

[0015] In some embodiments, a shielding ring is placed on the surface of the water bladder, and the shielding ring is stepped.

[0016] Compared with the prior art, the present invention provides a welding fixture for aluminum exterior wall panels, which has the following beneficial effects.

[0017] This invention, by setting up a negative pressure component, enables multiple suction cups to fix the aluminum plate under negative pressure, thereby avoiding the hard squeezing of the aluminum plate edges by mechanical clamping and effectively preventing the aluminum plate from undergoing elastic or plastic deformation due to excessive local stress; by setting up a sealing component, the suction cups not in use are sealed, thereby preventing air leakage from affecting the fixation of the aluminum plate, and it can be applied to fixing irregularly shaped aluminum plates.

[0018] This invention, by setting up an annular water bladder, after the suction cup is installed, the water bladder abuts against the outer periphery of the suction cup. The cooling water inside the water bladder absorbs the heat transferred to the vicinity of the suction cup during the welding process, effectively reducing the working environment temperature of the suction cup, preventing the air inside the adsorption chamber from expanding due to heat, and at the same time slowing down the aging rate of the suction cup, ensuring its long-term stable adsorption performance.

[0019] This invention, by setting up a constant pressure tank, allows the second spring to push the piston downward under the action of the piston, providing pressure for the return water, thereby ensuring that the water bladder maintains sufficient pressure expansion, keeps it in close contact with the suction cup, and tightly wraps around the outer periphery of the suction cup, ensuring good heat conduction and improving cooling efficiency.

[0020] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Reference Figure 1-12 A welding fixture for aluminum exterior walls includes a welding assembly mounted on the surface of a frame 1 and a fixture assembly for fixing the aluminum panels. The welding assembly includes a welding torch 3 and a gantry 2 for moving the welding torch 3 with multiple degrees of freedom. The gantry 2 slides on both sides of the frame 1 and is driven to move by a first threaded post. The first threaded post rotates at the bottom of the frame 1 and is driven to rotate by a drive motor. A translation frame 201 slides horizontally on the surface of the gantry 2 and is driven to move by a second threaded post. The second threaded post rotates at the top of the gantry 2 and is driven to rotate by a drive motor. A lifting frame 202 slides vertically on the surface of the translation frame 201 and is driven to slide vertically by a third threaded post. The third threaded post rotates inside the translation frame 201 and is driven to rotate by a drive motor. The welding torch 3 rotates on the surface of the lifting frame 202. A rotary joint 301 is located on the top of the welding torch 3. The rotary joint 301 is fixed to the top of the lifting frame 202 and is used to connect a cable to supply power to the welding torch 3. The welding torch 3 is driven to rotate by the transmission assembly 302. The transmission assembly 302 includes a worm and a worm wheel. The worm wheel is fixed to the surface of the welding torch 3, and the worm rotates on the upper surface of the lifting frame 202. The worm and the worm wheel mesh with each other. The worm is driven to rotate by a motor. A hook 303 for hanging the welding wire spool is fixed on the back of the translation frame 201.

[0036] Understandably, by setting up welding components, the gantry 2 drives the welding torch 3 to achieve multi-dimensional movement in the X, Y, and Z axes, thereby welding the aluminum plate; by setting up worm gears and worm wheels, the welding torch 3 is driven to rotate around its own axis, allowing the end of the welding torch 3 to rotate to different angles, thereby flexibly adjusting the welding angle and ensuring precise welding operations on welds at different positions and angles on irregularly shaped aluminum plates; by setting up hooks 303, the welding wire spool moves with the welding torch 3, preventing the welding wire from being pulled too long and breaking.

[0037] Specifically, the tooling components include a negative pressure component 4 for adsorbing and fixing the aluminum plate and a positioning component for positioning the aluminum plate. The negative pressure component 4 includes a base plate 401 fixed to the surface of the frame 1 and a top plate 402 fixed to the upper surface of the base plate 401. Multiple suction cups 403 are arrayed on the surface of the top plate 402. The suction cups 403 are mounted on the surface of the top plate 402 through mounting holes 404. The mounting holes 404 are opened on the upper surface of the base plate 401. An air passage 405 is opened on the upper surface of the base plate 401 to connect the multiple mounting holes 404. The air passage 405 includes a main air passage and multiple branch air passages. The multiple branch air passages are vertically intersecting and connected, and each branch air passage is connected to the main air passage. The main air passage is located in the middle of the multiple branch air passages. A sealing joint is connected to the end of the main air passage. The sealing joint is used to connect to the negative pressure air pump. The multiple mounting holes 404 are respectively located above the intersection of the branch air passages.

[0038] Understandably, by setting up the negative pressure component 4, multiple suction cups 403 are used to fix the aluminum plate under negative pressure, thereby avoiding the mechanical clamping from causing hard compression on the edge of the aluminum plate and effectively preventing the aluminum plate from undergoing elastic or plastic deformation due to excessive local stress. It can also be used to fix irregularly shaped aluminum plates. The negative pressure air pump is connected to the air channel 405 through the connector, so that multiple suction cups 403 can generate negative pressure at the same time to fix the aluminum plate. The air channel 405 adopts a design in which the main air channel and multiple branch air channels are vertically and cross-connected, which can ensure that each suction cup 403 can obtain a stable negative pressure source, ensure the consistency of the adsorption effect, and avoid the displacement of the aluminum plate during the welding process due to insufficient local negative pressure.

[0039] Specifically, a sealing component 5 for sealing the mounting hole 404 is provided inside the mounting hole 404. The sealing component 5 includes a sealing ring 501 fixed to the inner wall of the mounting hole 404 and a sealing head 502 that slides vertically inside the mounting hole 404. The bottom of the sealing ring 501 is provided with a first conical surface, and the upper surface of the sealing head 502 is provided with a second conical surface that cooperates with the first conical surface. The sealing head 502 slides on the inner wall of the mounting hole 404 via the sliding ring 504. The sliding ring 504 is fixed to the surface of the sealing head 502. A first spring 505 is fixed at the bottom of the sliding ring 504 to push the sealing head 502 against the surface of the sealing ring 501.

[0040] It is understandable that, since most of the exterior wall aluminum panels are irregularly shaped and come in many types, when fixing different aluminum panels, the suction cups 403 that cannot be covered by the aluminum panels may leak air, affecting the negative pressure adsorption of the suction cups 403 on the aluminum panels. Therefore, by setting the sealing component 5, the unused suction cups 403 are sealed to avoid air leakage affecting the fixing of the aluminum panels. When in use, the sealing head 502 slides downward and separates from the sealing ring 501, so that the air passage 405 is connected to the mounting hole 404 and the suction cup 403, thereby generating negative pressure in the suction cup 403.

[0041] Specifically, a top ring 503 is fixed to the bottom of the suction cup 403. The top ring 503 is used to push the sealing head 502 to separate from the sealing ring 501. The suction cup 403 is threaded into the mounting hole 404 through the top ring 503. Multiple through grooves 5031 are opened on the surface of the top ring 503.

[0042] Understandably, by setting the top ring 503, when installing the suction cup 403, the top ring 503 is threaded into the mounting hole 404. At the same time, the top ring 503 presses down on the sealing head 502, thereby connecting the air passage 405 with the suction cup 403 through the mounting hole 404 and the through groove 5031, generating negative pressure. When the suction cup 403 is not needed, it is disassembled, and the first spring 505 pushes the sealing head 502 to slide upward, abutting against the bottom of the sealing ring 501, thereby automatically sealing the mounting hole 404, preventing air leakage from the unused suction cup 403 interface, ensuring the sealing and stability of the negative pressure system, and is suitable for irregularly shaped aluminum plates of various shapes and sizes.

[0043] Specifically, a sealing ring 506 is fixed on the surface of the sealing head 502, and a sealing groove 507 that cooperates with the sealing ring 506 is opened on the lower surface of the sealing ring 501.

[0044] It is understandable that when the sealing head 502 and the sealing ring 501 come into contact, the sealing ring 506 is inserted into the sealing groove 507, thereby further improving the sealing effect between the sealing head 502 and the sealing ring 501.

[0045] Specifically, multiple water bladders 8 for cooling the suction cup 403 are fixed on the upper surface of the top plate 402. The water bladders 8 are annular and are connected by multiple first connecting pipes 801.

[0046] Understandably, during the welding process of the aluminum plate, the aluminum plate heats up, especially at the welding position. The suction cup 403 located at this position is affected by the high temperature. The air inside the adsorption chamber expands due to the high temperature, increasing the internal pressure and reducing the pressure difference with the external atmospheric pressure. This significantly reduces the adsorption force and stability. Furthermore, the high temperature causes the suction cup 403 material to age, its sealing performance to decrease, or even damage it, affecting adsorption stability and service life. Therefore, by setting up an annular water bladder 8, after the suction cup 403 is installed, the water bladder 8 presses against the outer periphery of the suction cup 403. The cooling water inside the water bladder 8 absorbs the heat transferred to the vicinity of the suction cup 403 during the welding process, effectively reducing the working environment temperature of the suction cup 403, preventing the air inside the adsorption chamber from expanding due to heat, and slowing down the aging rate of the suction cup 403, ensuring its long-term stable adsorption performance. Multiple water bladders 8 are connected by the first connecting pipe 801, allowing the cooling water to circulate among the water bladders 8, ensuring uniform cooling around all suction cups 403 and preventing damage to the suction cup 403 due to excessively high local temperatures.

[0047] Specifically, there are two sets of water bladders 8. The two sets of water bladders 8 are connected by a second connecting pipe 802. Both sets of water bladders 8 are connected to a constant pressure tank 803 through a hose. A water pump is installed at the end of one of the hoses. The water pump is used to transport water in the constant pressure tank 803 to one of the sets of water bladders 8. Inside the constant pressure tank 803, a piston 8031 ​​slides vertically. The piston 8031 ​​slides vertically at the bottom of the threaded rod 8032 via a connecting rod 8033. The threaded rod 8032 is threadedly connected to the top of the constant pressure tank 803. A second spring 8034 is sleeved on the surface of the connecting rod 8033 to push the piston 8031 ​​to slide downward. The surface of the constant pressure tank 803 is provided with multiple heat dissipation fins.

[0048] Understandably, by setting up a constant pressure tank 803, water from the constant pressure tank 803 is pumped to one set of water bladders 8 by a water pump. The water then flows through the second connecting pipe 802 to another set of water bladders 8, and then back to the constant pressure tank 803, forming a water circulation system to prevent localized overheating. By setting up a piston 8031, the second spring 8034 pushes the piston 8031 ​​downwards to provide pressure for the returning water, ensuring that the water bladders 8 maintain sufficient pressure expansion, keeping them in close contact with the suction cup 403 and tightly wrapping around its outer periphery, ensuring good heat conduction and improving cooling efficiency. Simultaneously, when the water bladders 8 expand due to increased water temperature, more... The remaining water can flow back into the constant pressure tank 803, pushing the piston 8031 ​​upward to compress the second spring 8034, buffering pressure changes and preventing excessive expansion of the water bladder 8 due to excessive pressure, which would cause the suction cup 403 to push the aluminum plate up, displacing the horizontal reference plane of the aluminum plate and affecting welding accuracy. The heat dissipation fins on the surface of the constant pressure tank 803 can accelerate the dissipation of heat from the cooling water inside the tank, maintaining the water temperature at a low level and further enhancing the cooling effect on the suction cup 403. By setting the threaded rod 8032, the threaded rod 8032 drives the piston 8031 ​​to slide upward, thereby drawing the water in the water bladder 8 into the constant pressure tank 803, causing the water bladder 8 to contract, making it easier to install the suction cup 403.

[0049] Specifically, the positioning assembly includes a positioning rod 6 for positioning the height of the aluminum plate and two positioning angle plates 7 for positioning the position of the aluminum plate. The positioning rod 6 is arranged in an array on the upper surface of the top plate 402 and is threadedly connected to the upper surface of the top plate 402. The two positioning angle plates 7 are located at opposite corners of the bottom plate 401 and are fixed to the upper surface of the bottom plate 401.

[0050] Understandably, since the suction cup 403 is made of a flexible material, it is difficult to keep the aluminum plate level using only the suction cup 403. Therefore, multiple positioning rods 6 are set to support the aluminum plate, thereby positioning the height of the aluminum plate. Two positioning corner plates 7 are set to make the aluminum plate abut against the surface of the positioning corner plates 7, thereby limiting the position of the aluminum plate. When welding the flat aluminum plate, multiple positioning rods 6 are adjusted to the same height. At this time, the height of the upper end of the positioning rod 6 is lower than the height of the suction cup 403. During adsorption, the negative pressure will cause the aluminum plate to slightly lower its height, so that the aluminum plate abuts against the surface of the positioning rod 6, thereby limiting the height of the aluminum plate. When welding aluminum plates with curved bottom surfaces, the height of the positioning rods 6 at different positions can be adjusted by rotating the positioning rods 6 according to the specific curvature of the aluminum plate's curved surface. This ensures that the top of each positioning rod 6 matches the bottom contour of the curved surface of the aluminum plate, forming multi-point support. This ensures that the aluminum plate can stably adhere to the curved trajectory supported by the positioning rods 6 during negative pressure adsorption, preventing the aluminum plate from shaking or deforming during welding due to unstable support. At the same time, the height of the suction cup 403 can be adjusted by adjusting the depth of the suction cup 403 in the mounting hole 404 to adapt to different positions of the aluminum plate and match the bottom contour of the curved surface of the aluminum plate. Meanwhile, the water bladder 8 wraps around the bottom of the suction cup 403. Under the action of the constant pressure tank 803, the pressure of the water bladder 8 automatically adapts to the expansion of the water bladder 8, maintaining the adhesion effect with the suction cup 403 and forming a seal on the bottom of the suction cup 403. This prevents air leakage at the threaded connection between the top ring 503 and the mounting hole 404, which would lead to insufficient negative pressure in the suction cup 403.

[0051] Specifically, the positioning assembly also includes a support assembly 9 for positioning the crossbeam. The support assembly 9 includes a fixing frame 901 that rotates on the side of the base plate 401 and a support block 902 fixed to the end of the fixing frame 901. The fixing frame 901 is L-shaped, and the support block 902 has a positioning groove 903 on the side facing the top plate 402. The fixing frame 901 is driven to rotate by a drive motor.

[0052] Understandably, when welding the crossbeam, the crossbeam is placed on the aluminum plate surface manually, and the fixed frame 901 and the support block 902 are rotated 90 degrees by the drive motor, so that the positioning groove 903 positions the crossbeam. At the same time, this can prevent the crossbeam from tilting.

[0053] Specifically, a shielding ring 10 is placed on the surface of the water bladder 8, and the shielding ring 10 is stepped.

[0054] Understandably, welding slag is easily generated during the welding process. In order to prevent the welding slag from splashing onto the surface of the water bladder 8, which could cause the water bladder 8 to break, or the welding slag from splashing into the mounting hole 404, which could cause the mounting hole 404 to become blocked or affect the sealing effect of the sealing head 502 and the sealing ring 501, a shielding ring 10 is set and placed on the surface of the unused water bladder 8 to shield and protect the water bladder 8 and the mounting hole 404.

[0055] In this invention, when welding irregularly shaped aluminum plates, the aluminum plate is manually placed on the surface of the suction cup 403 and pressed against the surfaces of the two positioning corner plates 7 to position the aluminum plate. Then, the suction cup 403 not covered by the aluminum plate is removed, causing the first spring 505 to push the sealing head 502 upward to slide against the bottom of the sealing ring 501, thereby automatically sealing the mounting hole 404, preventing air leakage from the unused suction cup 403 interface, ensuring the sealing and stability of the negative pressure system. This invention is suitable for irregularly shaped aluminum plates of various shapes and sizes. Simultaneously, the shielding ring... 10 is placed on the surface of the unused water bladder 8 to shield and protect the water bladder 8 and the mounting hole 404; the negative pressure air pump is connected to the air channel 405 through the connector, so that multiple suction cups 403 generate negative pressure at the same time to fix the aluminum plate. Under the action of the positioning rod 6, the aluminum plate is supported, so that the height of the aluminum plate can be positioned. When welding the aluminum plate, the gantry 2 drives the welding gun 3 to achieve multi-dimensional movement in the X-axis, Y-axis and Z-axis directions, so as to weld the aluminum plate. By rotating the welding gun 3 around its own axis, the end of the welding gun 3 can be rotated to different angles. The angle of welding can be flexibly adjusted to ensure precise welding of welds at different positions and angles on irregularly shaped aluminum plates. When welding the crossbeam, the crossbeam is placed manually on the surface of the aluminum plate. The drive motor rotates the fixing frame 901 and the support block 902 90 degrees, so that the positioning groove 903 positions the crossbeam. At the same time, it can prevent the crossbeam from tilting. By setting water bladders 8, water in the constant pressure tank 803 is transported to one set of water bladders 8 by a water pump. The water then flows to another set of water bladders 8 through the second connecting pipe 802, and then flows... The water returns to the constant pressure tank 803, forming a water circulation. The cooling water in the water bladder 8 absorbs the heat transferred to the vicinity of the suction cup 403 during the welding process, effectively reducing the working environment temperature of the suction cup 403 and preventing the air inside the adsorption chamber from expanding due to heat. Under the action of the piston 8031, the second spring 8034 pushes the piston 8031 ​​downward to pressurize it, providing pressure for the return water. This ensures that the water bladder 8 maintains sufficient pressure expansion, keeps it in close contact with the suction cup 403, and tightly wraps around the outer periphery of the suction cup 403, ensuring good heat conduction and improving cooling efficiency.
