Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy welding equipment, and in particular to a modular, rapid assembly, high-precision aluminum alloy welding equipment. Background Technology

[0002] With the booming development of the manufacturing industry, aluminum alloy materials, with their significant advantages such as light weight, high strength, and corrosion resistance, have been widely used in many key fields such as aerospace, automobile manufacturing, and building decoration. In the production process of aluminum alloy products, welding is a key process, and its quality directly determines the performance and service life of the product. For this reason, the market has put forward more stringent requirements for aluminum alloy welding equipment. It not only requires the equipment to have high-precision welding capabilities to ensure the quality and stability of the welded joints, but also to be able to flexibly adapt to the processing needs of aluminum alloy workpieces of different sizes and shapes, thereby effectively improving production efficiency and reducing production costs.

[0003] However, existing aluminum alloy welding equipment reveals numerous problems that urgently need to be addressed. When faced with welding aluminum alloy square tubes of varying lengths, traditional equipment exhibits significant limitations. Lacking an effective distance adjustment device, operators must frequently change clamps or adjust the overall equipment layout when dealing with square tubes of different lengths. This process is not only cumbersome but also time-consuming, resulting in extremely low production efficiency and failing to meet the urgent demands of modern production for rapid changeover. Furthermore, during the welding process, when welding different sides of the workpiece, the operation of traditional equipment is even more cumbersome. It typically requires removing the workpiece from the clamp, readjusting the clamping position, and then welding again. Repeated clamping operations not only greatly increase labor intensity, but also, due to the possibility of slight positioning deviations in each clamping, the error will continue to increase as the number of welding surfaces increases, thus seriously affecting welding accuracy and product quality. In addition, existing equipment also has many inconveniences in terms of height adjustment, making it difficult to accurately adjust the welding position according to different welding process requirements. This further limits the applicability of the equipment, preventing it from fully utilizing its performance and failing to meet diverse welding needs, thereby affecting welding quality. Based on the various problems existing in the above-mentioned technologies, it is of great practical significance to develop an aluminum alloy welding equipment that can easily adjust the clamping distance and height, has a flipping function, and can complete multi-sided welding in one clamping.

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Please see Figures 1-6 A modular, rapid assembly, high-precision aluminum alloy welding equipment includes a machine tool 1. A robotic arm 2 is fixedly connected to the side wall of the machine tool 1, and a high-precision welding head 3 is fixedly connected to the lower surface of the robotic arm 2. The robotic arm 2 and the high-precision welding head 3 are controlled by an external control system. Two symmetrically arranged fixed clamps 4 are slidably connected to the upper surface of the machine tool 1. A movable clamp 5 is slidably connected to the side wall of each fixed clamp 4. A screw 6 is threadedly connected to the inner wall of each movable clamp 5. The lower end of each screw 6 is rotatably connected to the inner wall of the adjacent fixed clamp 4. A handle 7 is fixedly connected to the upper end of each screw 6. By rotating the handle 7, the screw 6 is rotated, causing the movable clamp 5 to move on the side wall of the fixed clamp 4. The fixed clamps 4, movable clamps 5, screws 6, and handles 7 together form a clamping structure for clamping and fixing aluminum alloy square tubes. The machine tool 1 is equipped with a distance adjustment device and a height adjustment device.

[0050] Please see Figures 1-6The distance adjustment device includes a fixed block 8, which is fixedly connected to the lower surface of the machine tool 1. A screw 9 is installed inside the fixed block 8. The right end of the screw 9 penetrates the inner wall of the fixed block 8 and extends to the right end of the fixed block 8. The screw 9 is threadedly connected to the inner wall of the fixed block 8. The fixed block 8 provides support for the screw 9. The threads on the left and right halves of the screw 9 are opposite. A throttle 10 is fixedly connected to the left end of the screw 9. Two symmetrically arranged moving blocks 11 are provided on the surface of the screw 9. The left moving block 11 is threadedly connected to the left half of the surface of the screw 9, and the right moving block 11 is threadedly connected to the right half of the surface of the screw 9. The threads on the left and right halves of the screw 9 are opposite. When the screw 9 rotates, it causes the two moving blocks 11 to gradually approach or move away, thereby adjusting the distance between the two moving blocks 11. Each moving block 11 has a dovetail groove 12 on its side wall. Each dovetail groove 12 has a dovetail block 13 slidably connected to its inner wall. Each dovetail block 13 has a rectangular block 14 fixedly connected to its side wall. The rectangular block 14 can move smoothly axially on the moving block 11 through the dovetail groove 12 and the dovetail block 13. Each fixed clamp 4 has a long rod 15 fixedly connected to its side wall. The end of each long rod 15 away from the fixed clamp 4 passes through the side wall of the rectangular block 14 and extends to the other side of the rectangular block 14. Each long rod 15 away from the fixed clamp 4 has a rocker arm 16 fixedly connected to its end.

[0051] Please see Figures 1-6 Each long rod 15 includes a fixing ring 17, which is rotatably connected to the surface of the long rod 15. The fixing ring 17 is fixedly connected to the side wall of the moving block 11. Each fixing ring 17 has a slot 18 on its inner wall. Each long rod 15 has a placement groove 19 on its surface. A spring 20 is fixedly connected to the inner wall of each placement groove 19. A ball 21 is fixedly connected to the upper end of each spring 20. The ball 21 matches the slot 18. When the long rod 15 is rotated, the long rod 15 drives... Spring 20 and ball 21 rotate. Ball 21 is squeezed by the inner wall of slot 18. Spring 20 is compressed by the pressure of ball 21. Ball 21 moves out of slot 18 and enters placement slot 19. When it moves to the next slot 18, ball 21 is elastically pushed into slot 18 by spring 20, which has a certain fixing effect on long rod 15. Two symmetrically arranged support frames 22 are fixedly connected to the upper surface of machine tool 1. The surface of long rod 15 is slidably connected to the inner wall of support frame 22.

[0052] Please see Figures 1-6The height adjustment device includes a fixed block 23, which is fixedly connected to the lower surface of the machine tool 1. A double-ended gear rod 24 is installed inside the fixed block 23. The right end of the double-ended gear rod 24 penetrates the inner wall of the fixed block 23 and extends to the right side of the fixed block 23. Two symmetrically arranged adjusting rods 25 are meshed with the surface of the double-ended gear rod 24. When the double-ended gear rod 24 rotates, the adjusting rods 25 move axially through meshing. When the two moving blocks 11 move, the moving blocks 11 can drive the adjusting rods 25 to move horizontally on the surface of the double-ended gear rod 24. A fixed column 26 is fixedly connected to the left end of the double-ended gear rod 24. A movable rod 27 is installed on the fixed column 26. The front end of the movable rod 27 penetrates the surface of the fixed column 26 and extends to the outside of the fixed column 26. A fixed plate 28 is fixedly connected to the lower surface of the machine tool 1. A circular hole 29 is opened on the side wall of the fixed plate 28. The diameter of the circular hole 29 is larger than that of the movable rod 27. The front end of the movable rod 27 penetrates the inner wall of the circular hole 29 and extends to the front of the circular hole 29. When the movable rod 27 is inside the circular hole 29, the fixed column 26 cannot rotate, that is, the double-headed gear rod 24 cannot rotate, thereby restricting the two adjusting rods 25. The two adjusting rods 25 cannot move up and down. When the movable rod 27 is not inside the circular hole 29, the fixed column 26 can rotate. The height of the two adjusting rods 25 can be adjusted by rotating the fixed column 26 to drive the double-headed gear rod 24 to rotate.

[0053] Please see Figures 1-6 The machine tool 1 also includes a strip groove 30, which is formed on the upper surface of the machine tool 1. Each fixed clamp 4 has a strip slider 31 fixedly connected to its lower surface. Each strip slider 31 is slidably connected to the inner wall of the strip groove 30. By setting the strip groove 30 and the strip slider 31, the fixed clamp 4 and the movable clamp 5 can move horizontally smoothly on the machine tool 1.

[0054] Please see Figures 1-6 Each fixed clamp 4 has a dovetail groove 32 on its side wall, and each movable clamp 5 has a dovetail block 33 fixedly connected to its side wall. The dovetail block 33 is slidably connected to the inner wall of the dovetail groove 32. By setting the dovetail groove 32 and the dovetail block 33, when the screw 6 rotates, the movable clamp 5 can stably move axially on the side wall of the fixed clamp 4 through the dovetail groove 32 and the dovetail block 33.

[0055] Working principle: In use, two parts to be processed are placed on the fixed clamp 4 respectively. By rotating the screw 6 through the handle 7, the movable clamp 5 descends, and the aluminum alloy square tube is clamped by the fixed clamp 4 and the movable clamp 5. Then, the throttle 10 is rotated, the screw 9 rotates, and the two moving blocks 11 gradually approach each other until the two aluminum alloy square tubes contact each other. Then, the robotic arm 2 and the high-precision welding head 3 work to weld the two parts to be processed. Then, the movable rod 27 is moved out of the round hole 29, and the movable rod 27 and the fixed clamp 5 are connected to the fixed clamp 4. With the fixed column 26 in place, rotate the double-headed gear rod 24 clockwise. The two adjusting rods 25 rise simultaneously, driving the rectangular block 14, long rod 15, fixed clamp 4, and movable clamp 5 to rise. The two clamps then lift the aluminum alloy square tube to the appropriate height. Next, rotate the rocker arm 16, which drives the long rod 15 to rotate. This causes the fixed clamp 4 and movable clamp 5 to rotate the workpiece to the other side for welding. Once all four sides are welded, the operation can be reversed to remove the square tube and proceed to the next process.
