A wing installation and fixing mechanism

Abstract

The invention relates to a missile wing installing and fixing mechanism which comprises self-locking nuts (3), a longitudinal oblique tooth transmission rod (4), a transverse oblique tooth transmission rod (5), symmetrical clamping plates (6) and a shell (7). The longitudinal oblique tooth transmission rod (4) is inserted into a preset hole in skin (1). A gear of the bottom of the longitudinal oblique tooth transmission rod (4) is matched with a gear at one end of the transverse oblique tooth transmission rod (5). The transverse oblique tooth transmission rod (5) is screwed into thread holes of two symmetrical clamping plates (6). The missile wing installing and fixing mechanism is fixedly installed on the shell (7). According to the mechanism, the influence on aerodynamic performance is reduced greatly, missile wings are assembled and disassembled conveniently and rapidly, and for machining of the missile wing installing face, the requirement for matching precision is reduced greatly.

Description

technical field [0001] The invention belongs to the field of missile structure design, and relates to a missile wing installation and fixing mechanism, in particular to a missile wing installation and fixing mechanism with internal blind docking of missiles. Background technique [0002] The wing is the main provider of lift when the missile is in flight, and the conformal shape of the wing is the guarantee of the good aerodynamic performance of the missile. However, in the existing structural design, most of them adopt the fixing method of the body mounting seat. Due to the need for fixing, the mounting seat is generally thicker than the wing itself, which is prone to the following problems in practical applications: [0003] 1) Since most of the mounts are welded or bound, it is difficult to ensure the consistency of assembly; [0004] 2) Generally, the installation seat adopts the connection form of the card notch.

Problems solved by technology

However, in the existing structural design, most of them adopt the fixing method of the body mounting seat. Due to the need for fixing, the mounting seat is generally thicker than the wing itself, which is prone to the following problems in practical applications:

[0003] 1) Since most of the mounts are welded or bound, it is difficult to ensure the consistency of assembly;

[0004] 2) Generally, the installation seat adopts the connection form of the card notch. In order to play the role of lateral limit, the transition fit is generally used, and the processing accuracy of the installation seat and the wing is high;

[0005] 3) Since the processing accuracy and assembly accuracy of the mounting seat are difficult to guarantee a high level, it is easy to cause the actual performance to be inconsistent with the simulation performance, and there will be differences between individuals, which will cause certain difficulties in the design of the control system;

[0006] 4) The mounting seat exposes the surface of the missile body, forming multiple protrusions at the root of the wing, which has an extremely adverse effect on the aerodynamic performance of the wing and the entire missile, thereby restricting the relevant combat technical indicators of the missile
