Assembly jig for fuselage panel with cross-section radian greater than π and removal method thereof

Abstract

The invention discloses an assembly fixture for a fuselage wall plate with a cross-sectional radian greater than pi and a removing method thereof, and belongs to the technical field of aircraft assembly. By means of the assembly fixture for the assembly of the fuselage wall plate with the cross-sectional radian greater than pi, the fuselage wall plate is conveniently removed after assembly. The assembly fixture comprises a main fixture body which can be arranged in the fuselage wall plate and used for supporting the fuselage wall plate; when the fuselage wall plate is assembled, certain gaps are reserved between the outer contour of the main fixture body and the fuselage wall plate; support mechanisms are arranged in the gaps and comprise mounting bases, sleeve rods and positioning pins; one end of each sleeve rod is provided with a mounting plate distributed with the corresponding sleeve rod in an L-shaped mode, and the mounting plates are used for being connected with the fuselage wall plate. After the fuselage wall plate is assembled, the fuselage wall plate with the cross-sectional radian greater than pi can be very conveniently and smoothly removed from the assembly fixture.

Description

technical field [0001] The invention relates to the technical field of aircraft assembly, in particular to an assembly jig for a fuselage panel whose cross-sectional radian is larger than π and a removal method after the fuselage panel is assembled. Background technique [0002] Usually, when assembling the fuselage panel, the assembly frame of the fuselage panel is located on the inner side of the panel. There are two main reasons: 1. The outer side of the aircraft panel is a smooth and relatively continuous skin surface, while the main transmission of the panel Force structures, such as frames, beams, and long trusses, are all located on the inner side of the skin, and the assembly frame is placed on the inner side of the wall plate, so that the positioning datum and supporting structure can be conveniently selected on the main force transmission structure of the wall plate, and it is also more convenient. It is convenient to set positioners, supporters and other mechanism...

AI Technical Summary

Problems solved by technology

[0003] For fuselage panels whose cross-sectional radian is less than or equal to π, the panel is not easily blocked when it is removed from the assembly frame, so the removal process is very convenient; but for fuselage panels whose cross-sectional radian is larger than π , when the panel is removed from the assembly frame, it will easily interfere with the locator, supporter and other mechanisms on the assembly frame, which will lead to a very inconvenient process of removing the fuselage panel, and improper operation will easily cause the fuselage panel bruises, damages; serious economic losses
