Description

Technical Field

[0001] This utility model relates to the field of aircraft assembly technology, and in particular to a frame structure for assembling control surfaces of unmanned aerial vehicles. Background Technology

[0002] With the development of various aircraft technologies, advanced aircraft have adopted a flying wing configuration, which eliminates the vertical stabilizer and replaces it with an upper and lower coupled movable control surface as the key control surface for controlling the aircraft's deflection. The upper and lower coupled rudder replaces part of the function of the vertical stabilizer. This design can effectively control the aircraft's deflection and also has good stealth performance.

[0003] To achieve good flight control, the upper and lower movable control surfaces require strict control over their surface shape tolerances, edge profiles, and mating clearances. Previously, control surface assembly jigs assembled individual control surfaces, making it difficult to control the surface shape tolerances during mating, resulting in reduced assembly efficiency and a lower pass rate. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a frame structure for assembling control surfaces of unmanned aerial vehicles (UAVs) to solve the problems in the background art mentioned above.

[0005] The technical problem solved by this utility model is achieved by the following technical solution: A frame structure for assembling control surfaces of an unmanned aerial vehicle (UAV) includes an upper rudder upper wing surface profile clamping plate, a trailing edge limiter, two side limit clamping plates, a profile clamping device, a control surface support block, an edge limit support block, a lower rudder lower wing surface profile clamping plate, a joint locator, auxiliary clamping plates, a support frame, and a support plate. The support frame includes a crossbeam, a support base, and a bottom beam. The crossbeam is fixedly installed on the top of the support base, and the bottom beam is fixedly installed on the bottom of the support base. Auxiliary clamping plates are symmetrically arranged between the crossbeam and the bottom beam, with one end of each auxiliary clamping plate fixed to the crossbeam. The other end of the auxiliary clamping plate is fixed to the bottom beam; the joint locator is set on the crossbeam between the two auxiliary clamping plates, and support plates are symmetrically arranged on both sides of the auxiliary clamping plates. The upper rudder upper wing surface clamping plate and the lower rudder lower wing surface clamping plate are detachably installed on the support plates, and a surface clamping device and two side limiting clamping plates are installed on the support plate below the upper rudder upper wing surface clamping plate; at the same time, a trailing edge limiter and a rudder surface support block are set on the bottom beam between the two support plates, and the edge limiting support block is set on the bottom beam outside the support plate.

[0006] In this invention, the upper rudder upper wing surface profile plate and the lower rudder lower wing surface profile plate are detachable plates.

[0007] In this invention, the upper rudder upper wing surface profile plate and the lower rudder lower wing surface profile plate are engraved with part edge lines to assist in part positioning.

[0008] In this invention, the auxiliary card plate is a detachable card plate.

[0009] In this utility model, the bottom beam is provided with multiple mounting holes for mounting the tail edge limiter, the rudder surface support block, and the edge limit support block. After the tail edge limiter, the rudder surface support block, and the edge limit support block are moved to their theoretical positions, they are fixed with positioning pins.

[0010] In this invention, a bracket for supporting the limiting plates on both sides is provided on the inner side of the support base.

[0011] In this utility model, a pair of tail edge limiters are provided on the bottom beam, and the rudder surface support block is disposed between the pair of tail edge limiters.

[0012] Beneficial effects: In this utility model, the upper and lower control surface parts share the same assembly plate and the same positioning hole, and the same applies to the lower wing surface, which effectively ensures the consistency of control surface assembly. Moreover, the gap between the upper and lower control surfaces can be detected by a third-party testing tool, which is conducive to modifying and controlling the shape of the control surface. At the same time, controlling and adjusting the relative position of the upper and lower control surfaces improves assembly efficiency and the pass rate of control surface shape.
