Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) assembly technology, and in particular to a rotor strut assembly fixture. Background Technology

[0002] In the manufacturing process of electric vertical takeoff and landing (EVTOL) aircraft, the rotor strut is a critical component, and its assembly quality directly affects the aircraft's flight performance, safety, and reliability. Currently, rotor strut assembly often relies heavily on manual operations and complex processes. This not only leads to high assembly and manufacturing costs but also makes it difficult to avoid errors in manual operation, compromising assembly accuracy and consequently affecting the overall performance of the aircraft. For example, the lack of precise and effective positioning methods when positioning components such as the skin, brackets, short beams, front and rear docking frames, front and rear wing connection frames, and motor supports easily results in positional deviations. Ultimately, this leads to imbalances and vibrations in the rotor strut during actual operation, severely impacting the aircraft's flight stability and safety. Utility Model Content

The parting surface is located above the lower skin clamping plates, and multiple parting plates are arranged around it. A limiting opening is provided in the middle of the parting surface. An upper skin clamping plate is installed on the parting surface. The upper skin clamping plate, the lower skin clamping plate, and the limiting opening constitute the skin assembly area. Several positioners are also installed on the parting surface, and the positioners extend into the limiting opening.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the parting surface is assembled from multiple parting templates, with the multiple parting templates arranged around a circle to form a limiting opening in the middle.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the lower skin plate is positioned below the limiting port, and the upper skin plate is positioned above the limiting port, with the positions of the lower skin plate and the upper skin plate corresponding one-to-one.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the positioner includes a motor support positioner, a connecting frame positioner, a short beam positioner, a wing connecting frame positioner, and a bracket positioner, and all positioners are installed on the parting surface by fasteners.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the upper skin locator is provided on the template at both ends of the limiting port, and the lower skin locator is fixed on the frame body, with the upper skin locator and the lower skin locator being positioned opposite each other.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the main body of the frame is a rectangular structure, and several wheels and adjustable height support columns are provided below the main body of the frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The upper skin plate, lower skin plate, and template are used to limit the shape of the skin. Various locators are used to accurately position different components such as brackets, short beams, front and rear docking frames, front and rear wing connection frames, and motor supports. This ensures that each component can be accurately positioned during assembly, guarantees the assembly accuracy between the components of the rotor strut, and improves the overall assembly quality of the rotor strut, thus providing a guarantee for the flight performance and safety of the aircraft.

[0012] The parting surface is assembled from multiple parting templates, each of which can be disassembled individually. This facilitates the placement and assembly of different parts of the skin during the assembly process, and also makes it easier to disassemble and reassemble the skin after it has cured, further improving assembly efficiency.
