Problems solved by technology

In order to ensure the reliability of force transmission and good manufacturability, many connection forms use a large number of connecting parts, or adopt a complex overall forming structure, which makes it difficult to disassemble and assemble the airfoil. The disassembly and assembly time is too long or even impossible to disassemble. Meet the requirements of quick disassembly and assembly

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] See eg figure 1 , figure 2 , the mechanism consists of airfoil 1, cabin body 2, wing chassis I3, wing chassis II4, cabin chassis I5, cabin chassis II6, positioning pins 7 and fasteners 8. The wing chassis I3 is designed with a positioning pin hole that is interference fit with the positioning pin 7, and two through holes that are symmetrical about the chord plane; the wing chassis II4 is designed with two through holes that are symmetrical about the chord plane; the cabin chassis Ⅰ5 corresponds to the wing chassis Ⅰ3, which is designed with a positioning pin hole that is clearance-fitted with the positioning pin 7, and two threaded holes that are symmetrical about the chord plane; the cabin chassis Ⅱ6 corresponds to the wing chassis Ⅱ4 and is designed with two Symmetrical threaded holes; the positioning pin 7 is designed as a stepped pin with an exh...

Abstract

The invention relates to a quick disassembly and assembly structure of a wing disc connection, which is composed of a wing chassis, a cabin chassis, positioning pins (7) and fasteners (8); The wing chassis I (3) and the wing chassis II (4) have a cabin chassis I (5) and a wing chassis II (6) at corresponding positions on the cabin body (2), and positioning pins (7) are inserted into the wing The positioning pin holes on the chassis I (3) and the cabin body chassis I (5), the fasteners (8) realize the spanwise positioning of the airfoil (1) and the cabin body (2). The invention has the advantages of simple structure, reliable connection, good force transmission, and low manufacturing difficulty; simple connection mode, less fasteners, good openness, and rapid disassembly and assembly of the wings can be realized with common tools.

Description

technical field [0001] The invention belongs to the field of missile structure design, and in particular relates to a quick-disassembly structure for wing disc connection. Background technique [0002] At present, the ever-increasing operational requirements make the missile disassembly time and disassembly difficulty requirements are also increasing. In the structural design of the missile, there are many kinds of connection forms of the airfoil structure, including lug joints, multi-mortise joints, shaft joints, plug-in joints, dovetail joints and so on. In order to ensure the reliability of force transmission and good manufacturability, many connection forms use a large number of connecting parts, or adopt a complex overall forming structure, which makes it difficult to disassemble and assemble the airfoil. The disassembly and assembly time is too long or even impossible to disassemble. Meet the requirements of quick disassembly and assembly. Contents of the invention ...
