Compared to steel, they possess higher specific strength and superior processing performance. In the aerospace industry, aluminum alloy tubing is commonly used in critical components such as aircraft fuel systems, hydraulic systems, and cooling systems. Its lightweight properties help reduce the overall weight of the aircraft and improve flight efficiency, while its high strength ensures the stability and safety of the tubing under extreme flight conditions. Furthermore, aluminum alloy tubing also exhibits excellent corrosion resistance and high-temperature resistance, enabling it to operate stably for extended periods in complex aerospace environments.

[0003] A search revealed Chinese Patent Publication No. CN206509617U, which discloses the following: A portable aluminum alloy bracket for a welding fixture, relating to the field of aluminum alloy brackets. This portable aluminum alloy bracket for a welding fixture includes a base, with sleeves fixedly installed on both sides of the top of the base. A lead screw is rotatably connected inside each sleeve, and a nut is threaded onto the top of the lead screw. The tops of the two nuts are fixedly connected by a fixing plate. The bottom of the fixing plate has a through hole for installing the nuts, and the top of the nut is fixedly connected to the top of the inner cavity of the through hole. This portable aluminum alloy bracket for a welding fixture, through the arrangement of sleeves, lead screws, nuts, baffles, buffer plates, rods, partitions, push handles, and rollers, achieves the effect of convenient carrying of the aluminum alloy bracket. The aluminum alloy bracket can be disassembled and then fixed to the base, thus facilitating user carrying and improving the working efficiency of the aluminum alloy bracket.

[0004] Existing technologies require additional time to locate the weld seam, extending the overall welding operation time and increasing downtime and adjustment periods. Furthermore, existing technologies are inconvenient for material loading before welding and cannot perform welding steps continuously, thus increasing the production cycle. Therefore, we propose an aerospace-grade aluminum alloy welding bracket. Utility Model Content

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.

[0017] Example 1 Please see Figures 1-5As shown, an aviation aluminum alloy welding bracket includes a bracket body 1. Two legs 2 are fixedly connected to the bottom of the bracket body 1, arranged symmetrically. Rubber pads are fixedly connected to the bottom of each leg 2. The legs 2 provide support for the device, and the rubber pads increase the stability of the device during placement. An extension plate 3 is fixedly connected to the top of the bracket body 1. An electric cylinder 4 is fixedly installed on the outer side of the extension plate 3. A moving block 5 is fixedly connected to the telescopic end of the electric cylinder 4. A welding torch 6 is fixedly installed on one side of the moving block 5. An auxiliary welding torch 6 is also provided on the bracket body 1. The auxiliary welding structure 8 includes a primary motor 702, whose output shaft is fixedly connected to a primary pulley. Two strip-shaped holes 802 are opened at the top of the support body 1. Five secondary rotating rods 808 are rotatably connected to the inner side of the support body 1 via bearings. Each secondary rotating rod 808 has a primary gear 803 fixedly connected to its other end, and these primary gears 803 mesh with each other. Two rows of teeth are provided at the bottom of the bearing plate 701. Two secondary gears 807 are fixedly fitted onto the three secondary rotating rods 808 near the rotating structure 7. The bottom of plate 701 meshes with gear 807 (number 2) via two rows of teeth. The support plate 701 is L-shaped and contacts and slides against the walls of the two slotted holes 802. Under the meshing of gear 803, the bottom teeth of the support plate 701 move towards the welding gun 6, facilitating material loading. This allows for quick and accurate loading, reducing preparation time and enabling more continuous welding operations, thus shortening the production cycle. A pulley (number 2) is fixedly mounted on the surface of the second rotating rod 808. A reciprocating screw (804) is rotatably connected to the inner side of the extension plate 3 via bearings. A slider 806 is threaded onto the surface of the reciprocating lead screw 804. A limit rod 805 is fixedly connected to the inner side of the extension plate 3. The other end of the limit rod 805 extends through one side of the slider 806. The limit rod 805 limits the slider 806, making the slider 806 more stable during movement. A tracking sensor is fixedly installed on one side of the slider 806. A pulley 3 is fixedly connected to the other end of the second rotating rod 808. A pulley 4 is fixedly fitted onto the second rotating rod 808 located directly below the reciprocating lead screw 804. The pulley 3 and the pulley 4 are connected by a belt drive.

[0018] Furthermore, through the auxiliary welding structure 8, the bottom teeth of the support plate 701 move towards the welding gun 6 under the meshing of the first gear 803, thereby facilitating material feeding. This enables fast and accurate material feeding, reducing preparation time and allowing welding operations to be carried out more continuously, thus shortening the production cycle. During the feeding process, the slider 806 is equipped with a sensor to track the position and direction of the weld in real time. By tracking the weld in real time, the time spent on interruptions and adjustments during the welding process is reduced, making the welding process more continuous and efficient, and ensuring welding accuracy.

[0019] Example 2 Please see Figures 1-5 As shown, a rotating structure 7 is provided on the main body 1 of the support. The rotating structure 7 includes a bearing plate 701. A second motor 801 is fixedly installed on the outer side of the bearing plate 701. The output shaft of the second motor 801 is fixedly connected to a first rotating rod 703. Two fixing blocks 704 are fixedly sleeved on the surface of the first rotating rod 703. Electric telescopic rods 705 are fixedly installed on the top and bottom of the two fixing blocks 704 respectively. A stop plate 706 is fixedly connected to the telescopic end of the electric telescopic rod 705. The stop plate 706 is arc-shaped. The stop plate 706 is made of rubber, which can increase the friction when it hits the inside of the aluminum alloy tube, improve the stability of the aluminum alloy tube when it is fixed, and also avoid scratching the inside of the aluminum alloy tube. The tracking sensor is model SRT-HW. The tracking sensor is electrically connected to the electric cylinder 4. The first motor 702, the second motor 801 and the four electric cylinders 4 are electrically connected to an external power supply through wires.

[0020] Furthermore, through the rotating structure 7, the welding torch 6 can drive the two aluminum alloy tubes to be welded to rotate during the welding process, which facilitates welding operations in different positions and ensures all-round welding quality. During the rotation, the welding heat can be distributed more evenly in the welding area, reducing local overheating and welding defects.

[0021] In use, the aviation aluminum alloy welding bracket of this utility model involves fitting two aluminum alloy tubes to be welded onto the first rotating rod 703, ensuring that the adjacent ends of the two tubes are in contact. Then, the electric telescopic rod 705 is activated, using its telescopic end to move the abutment plate 706, which presses the inner sides of the aluminum alloy tubes together. Next, the second motor 801 is turned on, causing its output shaft to rotate the second rotating rod 808. The second rotating rod 808 then rotates the first gear 803. Through the meshing of the first gears 803, the four first gears 803s furthest from the tracking sensor rotate in the same direction. The bottom teeth of the support plate 701, under the meshing of the first gears 803, move towards the welding torch 6 until they stop below the welding torch 6, positioned below the tracking sensor. The rotation of the second rotating rod 808, through the belt transmission between the third and fourth pulleys, causes the second rotating rod 808, located at the tracking sensor, to drive the reciprocating screw 804 to rotate in the same direction. The limit rod 805 limits the slider 806, and the rotating reciprocating screw 804 drives the slider 806 to move back and forth. The sensor mounted on the slider 806 tracks the position and direction of the weld in real time to ensure the accuracy of the welding. Then, the tracking sensor transmits an electrical signal to the electric cylinder 4. The electric cylinder 4 drives the moving block 5 to move directly above the weld seam required on the pipeline. Then, the first motor 702 is turned on, and the output shaft of the first motor 702 drives the first rotating rod 703 to rotate. The first rotating rod 703 drives the two aluminum alloy tubes to rotate. Then, the welding torch 6 is turned on to weld the required weld seam with the rotating aluminum alloy tubes.
