Technical Field
[0001] This utility model belongs to the field of mechanical assembly technology, specifically relating to a flexible adsorption device for aircraft assembly. Background Technology
[0002] In aircraft assembly, the precise positioning and assembly of aircraft parts are crucial. Traditional aircraft assembly methods mostly rely on manual operation or fixed mechanical devices for gripping and installing parts. Manual operation is not only labor-intensive and inefficient, but also makes it difficult to guarantee assembly accuracy and consistency; fixed mechanical devices lack flexibility and cannot adapt to the assembly needs of aircraft parts with different shapes, sizes, and positions, thus failing to achieve efficient and precise operation in complex assembly environments. Therefore, this application proposes a flexible adsorption device for aircraft assembly. Utility Model Content

[0006] Preferably, the flexible adsorption structure includes a connecting plate assembled at the head end of the robotic arm, and multiple support arms are provided on the connecting plate. The multiple support arms are evenly arranged around the connecting plate, and each support arm is equipped with a vacuum suction cup.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This invention utilizes the multi-degree-of-freedom movement of a robotic arm and the horizontal movement of a support plate on a base to quickly and accurately adjust the position and orientation of a flexible adsorption structure, enabling rapid gripping and precise assembly of aircraft parts. This significantly shortens assembly time and improves production efficiency in aircraft assembly. Multiple vacuum suction cups within the flexible adsorption structure can be independently adjusted in position, adapting to the adsorption needs of aircraft parts of different shapes, sizes, and locations through the telescopic movement of electric push rods. Simultaneously, the multi-degree-of-freedom movement of the robotic arm allows the device to operate flexibly in complex three-dimensional space, adapting to various complex assembly environments and enhancing assembly flexibility and versatility. Furthermore, the combination of mechanical transmission and electric control allows for precise control of the movement trajectory and positional accuracy of the flexible adsorption structure, ensuring accurate docking of aircraft parts during assembly. This effectively improves the quality and precision of aircraft assembly and reduces quality problems caused by assembly errors. This device achieves automated gripping and assembly of aircraft parts, reducing manual operation steps, lowering the labor intensity of workers, improving the working environment, and also helping to reduce the impact of human factors on assembly quality.

[0020] 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.
[0021] This embodiment provides a flexible adsorption device for aircraft assembly, the structural schematic diagram of which is shown below. Figures 1-4 As shown, the device includes a base 1, a robotic arm 3, and a flexible adsorption structure 4. The base 1 is installed on the aircraft assembly station. Multiple mounting brackets 5 are arranged side by side at the bottom of the base 1, which are securely connected to the assembly station to ensure the stability of the entire device. The robotic arm 3 is mounted on the base 1 and is capable of multi-degree-of-freedom movement, allowing for flexible adjustment of its attitude and position. The flexible adsorption structure 4 is mounted at the head end of the robotic arm 3 and is used to adsorb aircraft parts and assemble them by controlling the robotic arm 3. The multi-degree-of-freedom adjustment and control of the robotic arm 3 allows the flexible adsorption structure 4 to adsorb aircraft parts for assembly operations.
[0022] Furthermore, a slide rail 6 is provided on the upper surface of the base 1. The slide rail 6 is arranged along the length of the base 1, and a pair of slide rails 6 are arranged side by side. A bearing plate 2 is slidably mounted on the pair of slide rails 6. The robotic arm 3 is mounted on the bearing plate 2. The bearing plate 2 can slide smoothly along the length of the slide rail 6. End plates 7 are provided at both ends of the base 1. The end plates 7 cover the ends of the slide rail 6 to prevent the bearing plate 2 from sliding out of the slide rail 6, thus playing a limiting and protective role.
[0023] In this embodiment, the robotic arm 3 is movably mounted on the base 1. The base 1 is provided with a drive mechanism for driving the robotic arm 3 to translate along the length direction of the base 1. The drive mechanism includes a rack 12 mounted on the base 1 and a motor 13 mounted on the support plate 2. The rack 12 is located on one side of the top of the base 1. A transmission gear 14 is provided on the output shaft of the motor 13. The transmission gear 14 meshes with the rack 12. When the motor 13 is running, the transmission gear 14 and the rack 12 mesh to drive the support plate 2 to move on the slide rail 6, thereby realizing the position adjustment of the robotic arm 3 in the length direction of the base 1.
[0024] In a further embodiment, the flexible adsorption structure 4 includes a connecting plate 8 mounted on the head end of the robotic arm 3. Multiple support arms 9 are provided on the connecting plate 8 and are evenly arranged around the connecting plate 8. Each support arm 9 is equipped with a vacuum suction cup 11, which is movably positioned at the end of the support arm 9 away from the connecting plate 8. An electric push rod 10 is vertically mounted on the support arm 9. The vacuum suction cup 11 is mounted on the telescopic end of the electric push rod 10. Through the telescopic movement of the electric push rod 10, the vacuum suction cup 11 can be adjusted in the vertical direction to adapt to the adsorption needs of aircraft parts of different heights and shapes.
[0025] Working principle:
[0026] When it is necessary to adjust the horizontal position of the flexible adsorption structure 4 on the aircraft assembly station, the motor 13 is started, and the output shaft of the motor 13 drives the transmission gear 14 to rotate. Since the transmission gear 14 meshes with the rack 12, under the action of the meshing force, the support plate 2 slides along the length direction of the slide rail 6, thereby driving the robotic arm 3 and the flexible adsorption structure 4 to move as a whole, realizing the adjustment of the horizontal position. Through its own multi-degree-of-freedom joint structure, the robotic arm 3 can further flexibly adjust the attitude and position of the flexible adsorption structure 4, so that it can accurately reach the location of the aircraft parts.
[0027] Once the flexible adsorption structure 4 reaches the appropriate position above the aircraft component, the electric push rod 10 extends, causing the vacuum suction cup 11 to move downwards and contact the surface of the aircraft component. The vacuum suction cup 11 is activated, creating a negative pressure inside, thus firmly adsorbing the aircraft component onto it. After adsorbing the aircraft component, the multi-degree-of-freedom movement of the robotic arm 3 and the horizontal movement of the support plate 2 on the base 1 precisely move the aircraft component to the assembly position. Upon reaching the assembly position, the electric push rod 10 retracts, causing the vacuum suction cup 11 and the aircraft component to move downwards, accurately aligning the aircraft component with the assembly area, completing the assembly operation. Afterwards, the vacuum suction cup 11 is closed, releasing the adsorption on the aircraft component, and the robotic arm 3 and support plate 2 reset, ready for the next assembly operation. This method is suitable for the automated assembly of thin-walled structural components such as aircraft panels, skins, and doors.
[0028] All technical features in this embodiment can be freely combined according to actual needs.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
