A Longitudinal Folding Airfoil Locking Mechanism

Abstract

The invention discloses a longitudinally-folding wing face locking mechanism which comprises a fixed joint, a taper pin, a bush, a driving lever, a spring, a baffle, a rotary joint and a rotary shaft. The taper pin is installed on the fixed joint. A kidney-shaped groove is formed in the side face of the fixed joint. The driving lever and the taper pin are connected through the kidney-shaped groove. The spring is arranged in the kidney-shaped groove. The taper pin, the spring, the driving lever and the fixed joint are assembled through the baffle and screws to form a sliding pair. The axis of the taper pin is parallel to that of the rotary shaft. The bush is embedded in the rotary joint. The axis of the bush and the axis of the taper pin are located in circles with the axis of the rotary shaft as the center, wherein the radii of the circles are equal. When the rotary joint is rotated to the locking position, the axis of the bush and the axis of the taper pin exactly coincide with each other, the taper pin is pressed into the bush under the effect of spring force, and the rotary joint is locked. The longitudinally-folding wing face locking mechanism is exquisite, simple in structure and convenient to detach and install; and the mechanism and the fixed joint are integrally designed and not warped by a protruding structure, and the pneumatic appearance is not damaged.

Description

technical field [0001] The invention belongs to the technical field of folding mechanisms, in particular to a locking mechanism for longitudinally folding airfoils. Background technique [0002] In order to reduce the hang-up space of the missile and miniaturize the launching device of the missile, it also makes the transportation and storage simple and convenient, increases the storage and transportation capacity of the storage and transportation device, and improves the combat capability of the weapon system. Deploys into place after air launch. With the widespread application of folding wings at home and abroad, the locking of folding wings is a key factor that affects the success of missile launch. At present, most of the folding wings of the one-wing layout at home and abroad adopt longitudinal folding, and the locking mechanism is an independent device, which takes up a large space. Areas protrude from the surface of the structure, even beyond the aerodynamic profile...
