Description
Technical Field
[0001] This utility model relates to the field of welding equipment technology, specifically to a robotic welding device for aluminum profile processing. Background Technology
[0002] Aluminum profiles are a lightweight, corrosion-resistant, and electrically conductive metallic material widely used in aerospace, automotive, construction, electronics, and other fields. They are one of the most widely used non-ferrous metal structural materials in industry.
[0003] The principle of aluminum profile welding is to melt aluminum or aluminum alloy materials using an electric arc or other heat source, and then, under certain pressure and protective gas, allow them to penetrate and fuse with the base material or filler metal, thereby achieving a connection. With the continuous development of technology, robotic welding has gradually replaced manual welding. Robotic welding has advantages such as stable welding quality, standardized work, reduced production costs, and prevention of errors.
[0004] However, existing robots can only weld rectangular aluminum profiles with a large cross-sectional area. When welding sheet aluminum profiles with a small cross-sectional area, the fixtures are difficult to adapt to the structure of the sheet aluminum profiles and hold them stably. This not only affects the welding quality of the sheet aluminum profiles, but may even cause the aluminum profiles to loosen and fall off. Utility Model Content
[0005] To solve the above-mentioned technical problems, a robotic welding device for aluminum profile processing is provided. This technical solution solves the problem mentioned in the background art. However, when welding aluminum profiles, existing robots can only weld rectangular aluminum profiles with a large cross-sectional area. When welding sheet aluminum profiles with a small cross-sectional area, the clamps are difficult to adapt to the structure of the sheet aluminum profiles for stable clamping. This not only affects the welding quality of sheet aluminum profiles, but may even cause the aluminum profiles to loosen and fall off.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A robotic welding device for aluminum profile processing includes a base plate, a robot assembly disposed at the top of the base plate, a worktable disposed on the left side of the base plate, a first clamping assembly disposed at the top left side of the worktable, a second clamping assembly disposed at the top right side of the worktable, and an operating table disposed at the front left end of the base plate. The first clamping assembly includes a mounting frame. A first telescopic cylinder is provided on the left side of the mounting frame. There are four sets of the first telescopic cylinders. A connector is fixedly installed on the telescopic end of each of the four sets of first telescopic cylinders. A movable rod is rotatably installed on the other end of each of the four sets of connectors. A fixed plate is rotatably installed on one end of each of the four sets of movable rods. The fixed plates are fixedly installed on the right side of the mounting frame. A clamping plate is fixedly installed on the other end of each of the four sets of movable rods.
[0007] Preferably, two sets of the movable rods are arranged in parallel and vertical positions, while the other two sets of movable rods are arranged horizontally.
[0008] Preferably, the second clamping assembly includes a bracket, and the bracket is provided in two sets. The top of each set of brackets is provided with a mounting plate, and the top of each set of mounting plates is provided with a second telescopic cylinder. The telescopic ends of each set of second telescopic cylinders are fixedly mounted with a connecting frame, and the other ends of each set of connecting frames are rotatably mounted with a rotating component.
[0009] Preferably, both sets of rotating parts are rotatably installed in slots opened inside the mounting plate, and both sets of rotating parts are provided with connecting plates on their inner sides, and both sets of connecting plates are fixedly installed with pressure plates at their bottom ends.
[0010] Preferably, the two sets of supports are symmetrically arranged on the worktable.
[0011] Preferably, the robot assembly includes a rotating disk rotatably mounted on the top of a substrate, a first swing arm movably mounted on the top of the rotating disk, a second swing arm rotatably mounted on the other end of the first swing arm, a rotating arm rotatably mounted on the left side of the second swing arm, and a weldment movably mounted on the other end of the rotating arm.
[0012] Compared with the prior art, the beneficial effects of this utility model are: First, by setting up a first clamping assembly, four sets of first telescopic cylinders drive the movable rods respectively. Through the rotational cooperation between the movable rods and the fixed plate, the clamping plate stably clamps the rectangular aluminum profile from multiple directions, achieving a reliable fixation effect for the rectangular aluminum profile. Second, by setting up a second clamping assembly, two sets of second telescopic cylinders drive the connecting frame, causing the rotating part to rotate within the groove of the mounting plate, thereby driving the connecting plate and the pressure plate to press down, achieving an effective pressing and fixing effect for the sheet aluminum profile. This effectively solves the problem of poor adaptability of existing robotic welding devices to aluminum profiles with different cross-sections, improving welding quality and stability.

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0016] Reference Figure 1-5 As shown, a robotic welding device for aluminum profile processing includes a base plate 1. A robot component 2 is disposed at the top of the base plate 1. A worktable 4 is disposed on the left side of the base plate 1. A first clamping component 5 is disposed at the top left side of the worktable 4. A second clamping component 6 is disposed at the top right side of the worktable 4. An operating table 7 is disposed at the front left end of the base plate 1. The first clamping component 5 includes a mounting frame 501. A first telescopic cylinder 502 is disposed on the left side of the mounting frame 501. Four sets of first telescopic cylinders 502 are provided. Connecting parts 503 are fixedly installed at the telescopic ends of the four sets of first telescopic cylinders 502. Movable rods 504 are rotatably installed at the other ends of the four sets of connecting parts 503. Fixed plates 505 are rotatably installed at one end of the four sets of movable rods 504. Fixed plates 505 are fixedly installed on the right side of the mounting frame 501. Clamping plates 506 are fixedly installed at the other ends of the four sets of movable rods 504. Two sets of movable rods 504 are arranged parallel and vertically, and the other two sets of movable rods 504 are arranged horizontally.
[0017] In this scheme, the synchronous extension and retraction of four sets of first telescopic cylinders 502 achieves uniform clamping force on the rectangular aluminum profile, effectively avoiding the deformation of the aluminum profile caused by uneven clamping force. The connecting piece 503 fixed at the extension end of the four sets of first telescopic cylinders 502 serves as an intermediate component for power transmission, converting the linear motion of the first telescopic cylinders 502 into the rotational motion of the movable rods 504. One end of each of the four movable rods 504 is rotatably mounted on the fixed plate 505, and the other end is fixedly mounted on the clamping plate 506. Two sets of movable rods 504 are arranged parallel and vertically, while the other two sets are arranged horizontally, enabling the clamping plate 506 to clamp the rectangular aluminum profile from multiple directions. Through the synergistic effect of clamping forces in different directions, a stable clamping of the rectangular aluminum profile is achieved, effectively preventing displacement of the rectangular aluminum profile due to vibration or external force during welding, and ensuring the stability of the welding process and the consistency of welding quality.
[0018] Reference Figure 5 As shown, the second clamping assembly 6 includes a bracket 601, which is provided in two sets. Each set of brackets 601 has a mounting plate 602 at its top. Each set of mounting plates 602 has a second telescopic cylinder 603 at its top. Each set of second telescopic cylinders 603 has a connecting frame 604 fixedly mounted on its telescopic end. Each set of connecting frames 604 has a rotating component 605 rotatably mounted on its other end. Each set of rotating components 605 is rotatably mounted in a slot opened on the inner side of the mounting plate 602. Each set of rotating components 605 has a connecting plate 606 on its inner side. Each set of connecting plates 606 has a pressure plate 607 fixedly mounted on its bottom end. The two sets of brackets 601 are symmetrically arranged on the worktable 4.
[0019] In this design, the telescopic movement of the second telescopic cylinder 603 drives the connecting frame 604 to move horizontally, allowing the rotating component 605 to rotate flexibly within the slot. This rotation of the rotating component 605 adjusts the angle of the connecting plate 606, which in turn drives the pressure plate 607 to rotate. Driven by the second telescopic cylinder 603, the two pressure plates 607 precisely press the aluminum profile placed on the workbench 4. Through the full contact between the pressure plate 607 and the surface of the aluminum profile, effective fixation of the sheet aluminum profile is achieved, further enhancing the stability of the sheet aluminum profile during welding and providing a reliable guarantee for high-quality welding. Reference Figure 3 As shown, robot component 2 includes a rotating disk 201, which is rotatably mounted on the top of the substrate 1. A first swing arm 202 is movably mounted on the top of the rotating disk 201. A second swing arm 203 is rotatably mounted on the other end of the first swing arm 202. A rotating arm 204 is rotatably mounted on the left side of the second swing arm 203. A welded part 3 is movably mounted on the other end of the rotating arm 204.
[0020] In this design, the rotating disk 201 can rotate flexibly at the top of the substrate 1, enabling the robot component 2 to rotate and adjust within a wide range in the horizontal direction. Through the extension and rotation of the first swing arm 202, the initial position adjustment of the welding part 3 in the vertical and horizontal directions is achieved. Through the rotation of the second swing arm 203, the position of the welding part 3 can be finely adjusted to meet the welding requirements of aluminum profiles of different shapes. Through the precise rotation control of the rotating arm 204, the welding part 3 is precisely aligned with the welding point of the aluminum profile, ensuring high precision and stability of the welding quality. The welding part 3, which is movably installed at the other end of the rotating arm 204, enables efficient welding of aluminum profiles of different materials and thicknesses, greatly improving the versatility and applicability of the device.
[0021] The working principle of this utility model is as follows: First, when the first clamping assembly 5 is working, the four sets of first telescopic cylinders 502 extend and retract synchronously. The connecting piece 503 fixed at its telescopic end transmits linear motion to the movable rod 504, causing the movable rod 504 to rotate around the fixed plate 505. This drives the clamping plate 506 to apply a uniform clamping force to the rectangular aluminum profile from multiple directions, preventing deformation of the aluminum profile and displacement during welding. Second, when the second clamping assembly 6 is working, the telescopic ends of the two sets of second telescopic cylinders 603 extend and retract, driving the connecting frame 604 to move horizontally. This causes the rotating piece 605 to rotate within the groove on the inner side of the mounting plate 602, driving the connecting plate... 606 adjusts the angle, thereby causing the pressure plate 607 to rotate, precisely pressing and fixing the sheet aluminum profile placed on the workbench 4, enhancing welding stability. Finally, when the robot component 2 is working, the rotating disk 201 rotates at the top of the base plate 1, achieving a wide range of horizontal rotation adjustment. The first swing arm 202 extends, retracts, and rotates, achieving initial position adjustment of the welded part 3 in the vertical and horizontal directions. The second swing arm 203 rotates, making fine adjustments to the position of the welded part 3. The rotating arm 204 rotates precisely, making the welded part 3 accurately aligned with the welding point of the aluminum profile. The welded part 3 efficiently welds aluminum profiles of different materials and thicknesses.
