Description

Technical Field

[0001] This invention belongs to the field of drone assembly technology, specifically relating to a positioning, hoisting and assembly device for the outer skin of a large-size drone fuselage and its usage method. Background Technology

[0002] The outer skin of a drone fuselage is typically made of lightweight materials (aluminum alloy, composite materials, etc.). These lightweight materials require special protection and handling during assembly and hoisting. The hoisting and assembly equipment needs to have functions such as precise positioning, material protection, and deformation prevention. The main body of commonly used hoisting and assembly equipment is a large frame made of welded square tubes. The frame is fixed to the ground with materials such as mortar. A large number of positioning units such as rigid clamps and metal blocks are installed inside the frame. After the fuselage is assembled, in order to unload the fuselage components smoothly, most of the positioning units integrated on the frame need to be disassembled. This not only causes a lot of time waste, but also increases the cost of on-site management after the positioning units are disassembled and the cost of restoring and reassembling the positioning units. Moreover, the stress release phenomenon that occurs in the drone fuselage after the positioning units are disassembled will also have an incalculable impact on the overall quality of the drone fuselage components.

[0003] After the drone fuselage skin is removed from the assembly line, the drone fuselage docking stage begins. The common approach is as follows: Overhead cranes or AGVs are used to transport the drone fuselage components to the final assembly docking fixture. Using characteristic points on the drone fuselage components (such as horizontal measurement points) as a reference, the components are moved to the target docking position. Simultaneously, the drone fuselage is adjusted to the correct docking attitude. Only after this adjustment can the docking operation be performed. This method requires specialized lifting fixtures and additional docking space. Furthermore, it relies on manual adjustment of the drone fuselage component position and attitude, which is time-consuming, extremely inefficient, and makes it difficult to guarantee docking quality. While high-precision automated equipment can replace manual adjustment and transport of drone fuselage components to ensure docking quality and efficiency, the significant equipment purchase and personnel training costs make it unsuitable for the current multi-model, small-batch manufacturing industry of large-size drones.

[0004] Ensuring the protective performance of the drone fuselage and outer skin during hoisting and positioning, preventing scratches and deformation, and ensuring the accuracy and quality of the outer skin during assembly are urgent problems to be solved. To address these issues, we propose a positioning, hoisting, and assembly device for large-size drone fuselage outer skin and its usage method. Summary of the Invention

[0028] A method for using a positioning, hoisting, and assembly device for the outer skin of a large-size unmanned aerial vehicle (UAV) fuselage includes the following steps:

[0029] A. Positioning and adsorption of the drone's outer skin:

[0030] First, confirm that the drone fuselage outer skin positioning and hoisting assembly device has been assembled and debugged and is in the correct position. Then, adjust the position of the first and second positioning suction cups using the threaded rod. Next, place the drone fuselage outer skin between the center hoisting frame and the side hoisting frame of the outer skin.

[0056] The method of using the large-size UAV fuselage outer skin positioning, hoisting, and assembly device provided by this invention includes the following steps:

[0057] A. Positioning and adsorption of the drone's outer skin:

[0058] First, confirm that the drone fuselage outer skin positioning and hoisting assembly device has been assembled and debugged and is in the correct position. Then, adjust the position of the first positioning suction cup 303 and the second positioning suction cup 504 by using the threaded rod. Then, place the drone fuselage outer skin between the outer skin center hoisting frame 1 and the outer skin side hoisting frame 2.

[0061] C. UAV assembly and docking:

[0062] Then, the two ends of the outer skin center hoisting frame 1 are aligned with the two UAV fuselage assembly docking frames 7 through the docking plate 801, and the docking plate 801 and the UAV fuselage assembly docking frame 7 are positioned and docked through the positioning guide post 802 and the threaded clamping pin, so that the outer skin center hoisting frame 1 and the UAV fuselage assembly docking frame 7 are positioned, docked and fixed.

[0063] D. Disassembly of the outer skin side lifting frame:

[0064] Before assembling the drone fuselage, the second positioning suction cup 504 is detached from the outer skin of the drone fuselage. Then, by unscrewing the L-shaped pin and threaded clamping pin at the first connecting piece 101 on the outer skin center lifting frame 1 and the outer skin side lifting frame 2, the outer skin side lifting frame 2 is removed from the outer skin center lifting frame 1.

This reduces the difficulty of installing and transporting the UAV fuselage outer skin while ensuring its quality and precision. By combining the positioning lifting assembly device with the integrated transport method of the UAV fuselage outer skin, the positioning accuracy of the UAV fuselage outer skin is ensured during transport, demonstrating high practical value.

[0066] The invention replaces the existing drone fuselage outer skin tooling frame, which requires a large number of positioning units to be customized and placed, and also requires manpower to restore them during subsequent use. The existing drone fuselage outer skin hoisting and assembly process takes nearly a week, while the invention can be completed in just half an hour, greatly improving the efficiency of drone fuselage outer skin positioning and hoisting.

[0067] Existing methods for docking drone fuselages require significant time, often exceeding two working days, to ensure the outer skin of the drone is in the correct docking position and attitude. This invention, however, requires only three hours to position the outer skin on the positioning and hoisting assembly device, and the docking position and attitude can be adjusted simply by hoisting it. Furthermore, the docking method using the positioning and hoisting assembly device requires less skill from personnel, necessitating only basic training rather than complex training in docking attitude adjustment or the use of digital equipment, thus broadening its applicability.

[0068] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
