Description
Technical field
The utility model belongs to radionavigation field, relates to a kind of aircraft antenna locking-adjustable mounting structure.
Background technology
At radio art, airborne radio installation often needs by antenna transmission or accepts electromagnetic wave, carries out communicating, navigating and identify response.General device, in installation process, is all adopt standard pallet nuts and bolt directly to fix, cannot carries out position adjustment.To in the working service process of radio navigation system, some antennas needs the strict axis of symmetry aiming at aircraft, due in Aircraft Production manufacture process, there is foozle and rigging error, therefore by pre-configured fixed installation hole, antenna alignment Installation and adjustment cannot be realized.
Summary of the invention
In order to solve the problem, the utility model provides a kind of aircraft antenna locking-adjustable mounting structure, realizes antenna alignment Installation and adjustment.
This utility model solves the technical scheme that its technical problem adopts: a kind of aircraft antenna locking-adjustable mounting structure, comprise astronomical cycle base plate, antenna high frequency feedback mouth, fuselage antenna mounting seat and four groups of supporting plate bolt assemblies that move about, described astronomical cycle base plate has four installation screws, described antenna high frequency feedback mouth is arranged on astronomical cycle base plate, on described fuselage antenna mounting seat, relevant position has antenna high frequency feedback oral pore, it is characterized in that: described travelling supporting plate bolt assembly is by bolt, rectangle nut and supporting plate composition, described supporting plate cross section is groove type, bottom surface has kidney-shaped to move about groove, limit has two rivet holes.Described fuselage antenna mounting seat board a plane axis specular position on have four identical kidney-shaped installing holes of groove size shape of moving about with kidney-shaped on supporting plate, the center of described four kidney-shaped installing holes is identical with the center of four screws on astronomical cycle base plate, and two kidney-shaped installing hole horizontal axiss become 70 ° of angles with axes of aircraft above, two kidney-shaped installing hole horizontal axiss become 50 ° of angles with axes of aircraft below, described four supporting plate rivets are fixed on the fuselage antenna mounting seat back side, on it, the kidney-shaped groove that moves about aims at kidney-shaped installing hole on fuselage antenna mounting seat, astronomical cycle base plate passes through installation screw on it by bolt, on fuselage antenna pedestal, on kidney-shaped installing hole and supporting plate, kidney-shaped is moved about after groove and is fixed by rectangle nut.Loose bolts, astronomical cycle base plate and bolt can move in supporting plate kidney-shaped moves about groove, when safeguarding navigation system, only need degree of tightness antenna set bolt, i.e. the orientation of adjustable antenna, aim at axes of aircraft.
The utility model has the advantage of that installing hole is joined out accurately in the position not needing to install navigation antenna on fuselage, by installing the mode of travelling supporting plate bolt assembly, the installation site of antenna on fuselage installed surface can be finely tuned, realize antenna alignment, reduce manufacture and assembly difficulty, reduce the scrappage of parts.
