Abstract

The invention discloses a measuring device for the folding angle of a wing. The measuring device comprises an installation part, one side of the installation part is a clamping part used for being connected and fixed with a wing folding rotating shaft, the other side of the installation part is a fixing plate, and the side, away from the installation part, of the fixing plate is equipped with an encoder; a measuring shaft of the encoder penetrates through the fixing plate and is located on the side, close to the installation part, of the fixing plate; a connecting arm is fixedly connected withthe measuring shaft of the encoder in a sleeving mode, and an adjusting plate is connected with the end, away from the encoder, of the connecting arm; and a wing surface connecting plate attached toa wing surface of a movable wing surface is arranged on the adjusting plate. According to the measuring device for wing folding angle, after installation, the wing surface connecting plate is ensuredto be attached to the surface of the wing, so that the wing drives the wing surface connecting plate to rotate in the folding process, a wing surface rotating plate drives the measuring shaft of the encoder to rotate through the connecting arm, thus the purpose of accurately measuring the folding angle of the wing is achieved through the encoder, and subsequent dynamic monitoring of wing folding can be realized conveniently.

Description

technical field [0001] The invention belongs to the technical field of wings, and in particular relates to a measuring device for wing folding angles. Background technique [0002] At present, due to the flight requirements of large unmanned aerial vehicles or fixed-wing aircraft, their wings are designed to be very long, and they occupy a large area when parked on ships. Therefore, large fixed-wing aircraft or long-wing aircraft parked on ships UAVs need to fold the wings after docking. The wings need to be folded accurately to the corresponding station before they can be locked and fixed. If there is an error in the wing folding angle, it will cause The wing is stuck or the wing lock fails. [0003] The wing folding process of the existing large fixed-wing aircraft or long-wing-span UAV is realized through the movement of the actuator on the wing under the action of hydraulic pressure, and the folding angle of the wing is currently also based on the actuating It is calcu...
