Description

Technical Field

[0001] This invention relates to the field of aluminum plate welding, specifically to an aluminum plate welding device with flattening and straightening functions. Background Technology

[0002] In the field of aluminum plate processing and manufacturing, aluminum plate welding is a key process for splicing and forming plates, and it is widely used in industries such as aerospace, automobile manufacturing, and building decoration. However, existing aluminum plate welding equipment has many limitations in practical applications and cannot meet the needs of efficient and high-precision welding in complex scenarios.

[0003] The main problems with existing technologies are as follows: Traditional welding equipment is mostly suitable for welding horizontally butt-jointed aluminum plates. When welding aluminum plates with specific angles (such as V-shape or L-shape), the positioning angle of the aluminum plate needs to be manually adjusted. Moreover, it is difficult for the two aluminum plates to keep the same axis and rotate synchronously, resulting in low angle adjustment accuracy and poor stability, making it unsuitable for welding scenarios with multiple angle bends.

[0004] When the angle between the aluminum plates changes, the alignment of the weld joint and the butt joint relies on frequent manual calibration, which can easily lead to problems such as welding deviation and missed welds due to positioning errors, seriously affecting the welding quality.

[0005] Therefore, there is an urgent need for a welding device that can adapt to multiple scenarios, provide high-precision positioning, and is compatible with aluminum plates of various thicknesses, in order to solve the aforementioned problems in the existing technology. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the above-mentioned difficulties and provide an aluminum plate welding device with flattening and straightening function.

[0007] A welding device for aluminum plates with flattening and straightening functions includes a device base and a driving device. Several aluminum plate positioning transmission mechanisms are arranged in a corresponding manner inside the device base. A clamping and conveying assembly is provided on a corresponding set of aluminum plate positioning transmission mechanisms, and all aluminum plate positioning transmission mechanisms are driven simultaneously by the driving device. The clamping and conveying assembly includes two corresponding clamping and conveying mechanisms. The aluminum plate positioning transmission mechanism is arc-shaped and the clamping and conveying mechanism can move along the fixed axis of the aluminum plate positioning transmission mechanism. The aluminum plate is conveyed by the clamping and conveying mechanism. One set of clamping and conveying assemblies is provided with two centering welding parts that can be welded to the top and bottom of the aluminum plate respectively.

[0008] As an improvement, the aluminum plate positioning transmission mechanism includes an arc-shaped frame fixed to the device base. Several arc-shaped transmission gears are arranged inside the arc-shaped frame. A transmission toothed belt is provided outside the transmission gears, and the transmission gears are driven by the transmission toothed belt through meshing. Several driven gears are provided inside the arc-shaped frame, which correspond one-to-one with the positions of the transmission gears and mesh with the transmission toothed belt. The driven gears are located at the inner ring of the transmission gears, and the aluminum plate positioning transmission mechanism drives the clamping and conveying mechanism to move through the driven gears.

[0009] As an improvement, the clamping and conveying mechanism includes a slider with arc-shaped teeth that mesh with driven gears. The arc-shaped teeth achieve the function of fixed-axis motion by meshing with several driven gears in sequence. An arc-shaped slide rod is provided on the inner end face of the arc-shaped frame. The slider is provided with through holes and is slidably connected to the arc-shaped slide rod through the through holes.

[0010] As an improvement, the slider is equipped with rods at both the top and bottom ends. The rods are equipped with roller frames that are inserted into the rods and located inside the rods. The roller frames are equipped with conveying rollers that contact the aluminum plate. The upper rods are equipped with electric telescopic rods whose telescopic ends are fixed to the roller frames. The slider is equipped with a first groove at the inner end, and a second transmission gear is installed in the first groove. The roller frames are equipped with a transmission gear plate that meshes with the second transmission gear at the end.

[0011] As an improvement, a second slide groove is provided on the upper roller frame, and a first slide rod is provided inside the second slide groove. A rotating block is provided at the end of the conveying roller, which is slidably connected to the first slide rod and located inside the second slide groove. A spring is provided on the rotating block and sleeved on the outside of the first slide rod.

[0012] As an improvement, the centering welding component includes a fan-shaped housing that abuts against the corresponding rod end. A vertical bevel gear is rotatably provided inside the housing. Both sides of the bevel gear are provided with driven tooth plates that mesh with the bevel gear and are fan-shaped. The two driven tooth plates are respectively fixed to the corresponding rod end. A mounting frame is provided at the center of the housing, and a welding device is slidably provided inside the mounting frame. When the two mating aluminum plates bend downwards relative to each other, the angle at the top between the two aluminum plates increases and the angle at the bottom decreases. That is, when the aluminum plates are in a horizontal state, the driven toothed plate in the lower centering weldment extends out of the housing, while the driven toothed plate in the upper centering weldment is completely located inside the housing.

[0013] As an improvement, a fixed bracket is provided at the top of the welder, and a positioning wheel that rolls on the aluminum plate is provided at the bottom of the fixed bracket. A spring is provided between the bottom of the mounting bracket and the welder, which is fitted around the outside of the welder.

[0014] As an improvement, a deburring structure is provided on the side end face of the pole frame. The deburring structure includes a fixed frame 1 fixed to the pole frame, a support rod 1 slidably inserted on the fixed frame 1, a spring 3 sleeved on the outside of the support rod 1, and a straightening pressure roller at the end of the support rod 1 that applies pressure to the end of the aluminum plate under the action of the spring 3. A deburring scraper is rotatably provided at the end of the straightening pressure roller that can scrape off the burrs on the edge of the aluminum plate to be welded.

[0015] As an improvement, aluminum plate docking mechanisms are provided on both ends of the slider. The aluminum plate docking mechanism includes a fixed frame 2 fixed to the slider, a support rod 2 slidably inserted on the fixed frame 2 and a spring 4 sleeved on the outside of the support rod 2, and a docking roller at the end of the support rod 2 that is rolled to the aluminum plate and can apply pressure to the aluminum plate and push the aluminum plate to dock.

[0016] The advantages of this invention compared to the prior art are as follows: This invention utilizes a drive device to synchronously drive an arc-shaped aluminum plate positioning transmission mechanism. Through the meshing of a transmission gear, a transmission belt, and a driven gear, the clamping and conveying mechanism moves along a fixed axis within the arc-shaped frame, ensuring that the aluminum plates on both sides rotate synchronously around the same axis, thus controlling the angle. Simultaneously, the clamping and conveying mechanism always rotates around a fixed axis, guaranteeing that one end of the aluminum plate remains at the axis's center even when the angle changes. This significantly improves the accuracy and stability of angle adjustment, making it suitable for welding aluminum plates from horizontal to multi-angle bends.

[0017] 2. The centering welding component is linked by the meshing of a bevel gear and a driven gear plate. When the angle between the aluminum plates changes, the driven gear plate drives the bevel gear to rotate, so that the housing and the welding device always keep the axis of symmetry of the joint with the aluminum plate. That is, the welding device is always directly facing the joint gap, avoiding welding deviation and missed welding. At the same time, the positioning wheel and the spring work together to ensure that the distance between the welding device and the aluminum plate is stable, eliminating the need for manual calibration and significantly improving welding accuracy and consistency.

[0018] 3. The clamping and conveying mechanism drives the roller frame to move relative to each other through an electric telescopic rod, so as to achieve stable clamping of aluminum plates of different thicknesses by the upper and lower conveying rollers. The relative movement of the two roller frames ensures that the edge of the aluminum plate is always in the axial position, which guarantees the accuracy of subsequent welding of the aluminum plate.

[0029] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 As shown: A welding device for aluminum plates with flattening and straightening function includes a device base 1 and a driving device 4. Several aluminum plate positioning transmission mechanisms 2 are arranged in the device base 1. A set of aluminum plate positioning transmission mechanisms 2 is equipped with a clamping and conveying assembly, and all aluminum plate positioning transmission mechanisms 2 are driven simultaneously by the driving device 4. The clamping and conveying assembly includes two clamping and conveying mechanisms 3 arranged in a corresponding manner. The aluminum plate positioning transmission mechanism 2 is arc-shaped, and the clamping and conveying mechanism 3 can move along the fixed axis of the aluminum plate positioning transmission mechanism 2. The aluminum plate is conveyed by the clamping and conveying mechanism 3. One set of clamping and conveying assemblies is equipped with two centering welding parts 5 that can be welded to the top and bottom of the aluminum plate respectively.

[0030] When welding aluminum plates in a docking state, the drive device 4 first drives the clamping and conveying mechanism 3 to perform fixed-axis movement on the aluminum plate positioning and transmission mechanism 2 through the aluminum plate positioning and transmission mechanism 2. The aluminum plate positioning and transmission mechanism 2 determines the included angle between the two aluminum plates through movement. Then, the clamping and conveying mechanism 3 is started to transport the aluminum plates. During the process, the centering welding part 5 can weld the aluminum plates.

[0031] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 As shown: The aluminum plate positioning transmission mechanism 2 includes an arc-shaped frame 201 fixed to the device base 1. Several arc-shaped transmission gears 202 are arranged inside the arc-shaped frame 201. A transmission toothed belt 203 is provided outside the several transmission gears 202, and the transmission gears 202 are driven by the transmission toothed belt 203 through meshing. Several driven gears 204 are provided inside the arc-shaped frame 201, which correspond one-to-one with the positions of the transmission gears 202 and mesh with the transmission toothed belt 203. The driven gears 204 are located at the inner ring of the transmission gears 202, and the aluminum plate positioning transmission mechanism 2 drives the clamping and conveying mechanism 3 to move through the driven gears 204. The clamping and conveying mechanism 3 includes a slider 301, on which arc-shaped teeth 303 mesh with driven gears 204. The arc-shaped teeth 303 achieve the function of fixed-axis motion by meshing with several driven gears 204 in sequence. An arc-shaped slide rod 205 is provided on the inner ring end face of the arc-shaped frame 201. A through hole 304 is provided on the slider 301 and is slidably connected to the arc-shaped slide rod 205 through the through hole 304. The slider 301 has a rod frame 302 at both the upper and lower ends. The rod frame 302 has a roller frame 306 that is inserted into the rod frame 302 and located inside the rod frame 302. The roller frame 306 has a conveying roller 308 that contacts the aluminum plate. The upper rod frame 302 has an electric telescopic rod 307 whose telescopic end is fixed to the roller frame 306. The slider 301 has a first groove 305 at the inner end. The first groove 305 has a second transmission gear 310 in the first groove 305. The roller frame 306 has a transmission tooth plate 309 that meshes with the second transmission gear 310 at the end. The upper roller frame 306 is provided with a corresponding slide groove 311, and a slide rod 312 is provided inside the slide groove 311. The end of the conveying roller 308 is provided with a rotating block that is slidably connected to the slide rod 312 and located inside the slide groove 311. A spring 313 is provided on the rotating block and sleeved on the outside of the slide rod 312.

[0032] In order to make the present invention applicable to aluminum plates with different included angles, an aluminum plate positioning transmission mechanism 2 driven by a driving device 4 is provided. When the aluminum plate positioning transmission mechanism 2 is working, it can drive the clamping and conveying mechanism 3 to move along the fixed axis of the aluminum plate positioning transmission mechanism 2. The drive device 4 includes a drive motor, a drive shaft, and several meshing gears corresponding to the positions of the aluminum plate positioning transmission mechanism 2. When the drive motor starts, the drive gears rotate, and the gears drive the transmission belt 203 to rotate. At this time, the corresponding transmission belt 203 rotates in opposite directions, so that the corresponding clamping and conveying mechanism 3 moves in opposite directions. The transmission belt 203 drives the first transmission gear 202 and the driven gear 204 to work simultaneously. Since the first transmission gear 202 and the driven gear 204 are in corresponding positions, the first transmission gear 202 and the driven gear 204 can mesh to lock the transmission belt 203, thus preventing the transmission belt 203 from dislodging under heavy load. When the driven gear 204 rotates, it drives the slider 301 to move along the arc-shaped slide bar 205 on the arc-shaped frame 201 under the meshing of the arc-shaped gear 303. During the process, the slider 301 always rotates around the straight line where the center of the arc-shaped frame 201 is located. That is, when the clamping and conveying mechanism 3 clamps the aluminum plate, the aluminum plate rotates around the axis with one end as the axis. When the clamping and conveying mechanism 3 rotates to the predetermined angle, the drive device 4 is turned off. At this time, the aluminum plate can be conveyed and welded. When feeding aluminum plates, since the aluminum plates in the existing technology have multiple thicknesses, in order to ensure that one end of the aluminum plates of different thicknesses is always at the axis when the included angle changes, the electric telescopic rod 307 needs to be activated to retract before welding the aluminum plate. Then, the aluminum plate is placed between the two conveying rollers 308. After that, the electric telescopic rod 307 is activated to extend. Since the transmission gear plates 309 on the two roller frames 306 are engaged with the transmission gear 310, the electric telescopic rod 307 can drive the two roller frames 306 to move relative to each other so that the conveying rollers 308 clamp the aluminum plate. The spring 313 can prevent the conveying rollers 308 from making rigid contact with the aluminum plate, so as to avoid damage to the aluminum plate.

[0033] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 7 As shown: The centering welding component 5 includes a fan-shaped housing 501 that abuts against the end of the corresponding rod 302. A vertical bevel gear 502 is rotatably provided inside the housing 501. Both sides of the bevel gear 502 are provided with fan-shaped driven tooth plates 503 that mesh with the bevel gear 502. The two driven tooth plates 503 are respectively fixed to the end of the corresponding rod 302. A mounting bracket 504 is provided at the center of the housing 501. A welder 505 is slidably provided inside the mounting bracket 504. When the two mating aluminum plates bend downwards relative to each other, the angle at the top between the two aluminum plates increases and the angle at the bottom decreases. That is, when the aluminum plates are in a horizontal state, the driven toothed plate 503 in the lower centering welded part 5 extends out of the housing 501, and the driven toothed plate 503 in the upper centering welded part 5 is completely located inside the housing 501. The welding device 505 has a fixed bracket 507 at the top, and a positioning wheel 508 that rolls on the aluminum plate at the bottom of the fixed bracket 507. A spring 506 that is sleeved on the outside of the welding device 505 is provided between the bottom of the mounting bracket 504 and the welding device 505.

[0034] To ensure that the welder 505 on the centering weldment 5 always aligns with the axis of symmetry at the joint with the aluminum plate, i.e., the welder 505 is directly opposite the joint gap of the aluminum plate, the welder 505 is mounted at the center of the housing 501 via the mounting bracket 504. Since the two driven toothed plates 503 are respectively fixed to the ends of the corresponding rods 302, when the clamping and conveying mechanism 3 moves, the rods 302 will drive the driven toothed plates 503 to move around the axis, and at the same time, the driven toothed plates 503 will drive the bevel gear 502 to rotate. Since the corresponding clamping and conveying mechanisms 3 have the same rotation angle and opposite directions, the position of the bevel gear 502 does not change during the movement of the driven toothed plates 503, i.e., the position of the housing 501 is fixed, so that the welder 505 is always in a vertical state. The welder 505 is prior art and will not be described in detail in this invention. When welding aluminum plates, the distance between the welding machine 505 and the aluminum plate is determined by the state of contact between the positioning wheel 508 and the aluminum plate. That is, the distance between the welding machine 505 and the aluminum plate remains constant. When the thickness of the aluminum plate changes, the aluminum plate will press the positioning wheel 508 as it passes through the positioning wheel 508. The positioning wheel 508 drives the welding machine 505 to move up and down through the fixed bracket 507, and at the same time, the welding machine 505 is started to perform welding work on the aluminum plate. It is worth noting that, in the specific implementation of this invention, when the drive device 4 drives only one aluminum plate to rotate on a fixed axis, while the other aluminum plate is fixed in position, the orientation of the welder 505 always coincides with the axis of symmetry of the two aluminum plates, that is, it faces the joint of the two aluminum plates. Specifically, when one aluminum plate rotates, that is, when one driven toothed plate 503 moves, it will drive the bevel gear 502 to rotate under the meshing with the bevel gear 502. Since the other aluminum plate is fixed, that is, the other driven toothed plate 503 is fixed, the rotating bevel gear 502 will roll on the fixed driven toothed plate 503. The bevel gear 502 drives the welder 505 to rotate on a fixed axis through the housing 501, and the rotation angle of the welder 505 is half the rotation angle of the driven toothed plate 503.

[0035] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 8 As shown: A deburring structure 6 is provided on the side end face of the end of the rod 302. The deburring structure 6 includes a fixed frame 601 fixed to the rod 302. A support rod 602 is slidably inserted into the fixed frame 601. A spring 605 is sleeved on the outside of the support rod 602. A straightening pressure roller 603 is provided at the end of the support rod 602, which applies pressure to the end of the aluminum plate under the action of the spring 605. A deburring scraper 604 is rotatably provided at the end of the straightening pressure roller 603, which can scrape off the burrs on the edge of the aluminum plate to be welded.

[0036] To ensure that the edge of the aluminum plate to be welded is flat and smooth during welding, a deburring structure 6 is provided. When the aluminum plate passes through the deburring structure 6, the straightening roller 603 is squeezed by the elastic force of the spring 605. When the thickness of the aluminum plate changes, the degree of compression of the spring 605 changes accordingly, and the pressure of the straightening roller 603 on the aluminum plate also changes accordingly. The deburring scraper 604 is slidably connected to the edge of the aluminum plate. When the aluminum plate moves, the deburring scraper 604 can scrape off the burrs on the aluminum plate.

[0037] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 9 As shown: Both ends of the slider 301 are provided with aluminum plate docking mechanisms 7. The aluminum plate docking mechanism 7 includes a fixed frame 2 701 fixed to the slider 301. A support rod 2 702 is slidably inserted on the fixed frame 2 701 and a spring 4 704 is sleeved on the outside of the support rod 2 702. The end of the support rod 2 702 is provided with a docking roller 703 that is rolled to the aluminum plate and can apply pressure to the aluminum plate and push the aluminum plate to dock.

[0038] Before welding the aluminum plates, the two aluminum plates need to be put together. That is, the present invention provides aluminum plate docking mechanism 7 at both ends of the slider 301 to push the aluminum plates. That is, the docking roller 703 is rolled to the aluminum plate, and the aluminum plate is pressed and pushed by the spring 704 to dock.

[0039] In the specific implementation of the aluminum plate welding device with flattening and straightening function, firstly, according to the required included angle of the aluminum plate to be welded, the drive device 4 is started. The drive device 4 drives the aluminum plate positioning transmission mechanism 2 to work, driving the slider 301 to move along the arc-shaped slide bar 205 on the arc-shaped frame 201 to make a fixed axis movement. After adjusting to the predetermined included angle, the electric telescopic rod 307 is started to retract, placing the aluminum plate between the upper and lower conveying rollers 308. Then, the electric telescopic rod 307 is started to extend, and the two roller frames 306 move relative to each other. Spring 1 313 can prevent the conveying rollers 308 from rigidly contacting the aluminum plate and causing damage. The straightening pressure roller 603 of the deburring structure 6 applies pressure to the end of the aluminum plate under the action of spring 3 605, while the deburring scraper 604 scrapes off the burrs. The docking roller 703 of the aluminum plate docking mechanism 7 pushes the aluminum plate to fit together under the action of spring 4 704. When the drive device 4 is activated, the centering welding part 5 is adjusted accordingly. The clamping and conveying mechanism 3 moves, driving the driven toothed plate 503 to move around the axis. The welder 505 is always facing the gap between the aluminum plates. The positioning wheel 508 contacts the aluminum plate to ensure that the distance between the wheel and the aluminum plate is fixed. The second spring 506 assists in the adjustment. The welder 505 starts to weld the top and bottom of the aluminum plate.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
