The invention relates to a step-by-step shearing type automatic release device for a directional button, which belongs to the field of civilian rockets. A step-by-step shearing type directional button automatic release device of the present invention includes a locking screw, a directional button, a positioning cylinder, a pull rod, a support block and a screw cover; The rectangular hole on the table, the outer plate surface of the locking screw connection hole at the front end of the pull rod is welded to fix the directional button, and the locking screw passes through the stepped through hole in the center of the directional button, so that the front end is threadedly connected with the threaded hole on the side wall of the projectile body; the pull rod The inner board surface at the connecting hole of the rear end support block fixes the support block by screws, and the front end of the support block is against the side wall of the projectile body, so that the pull bar is parallel to the axis of the projectile body. The automatic release device of the directional button of the present invention has simple structure and convenient assembly. On the basis of ensuring the original positioning, locking and other basic functions, it realizes the automatic release function when launching, greatly improves the adaptability of civilian guided rockets, and has important advantages. Promote application value.
Description
technical field [0001] The invention relates to a step-by-step shearing type automatic release device for a directional button, which belongs to the field of civilian rockets. Background technique [0002] During the transportation of civilian rockets, the directional button located at the tail of the rocket is mainly used for positioning, guiding and locking; during the launch process, it cooperates with the spiral guide groove of the rocket barrel to ensure that the rocket will rotate at a low speed after ejecting from the muzzle Movement to reduce the adverse effects of engine thrust eccentricity and projectile shape asymmetry. [0003] At present, civil rockets are developing towards precision guidance, and their inertial navigation system cannot work normally when the projectile body is rotating. can fall off automatically. [0004] Although the existing structure can realize the shedding function of the directional button, it needs to be manually operated before the ...
