Problems solved by technology

[0004] The fuselage of the aircraft is a typical cylindrical structure formed by splicing and joining together several panels. Insufficient, the present invention takes six panels as an example to provide a flexible positioning method for fuselage panels, and realizes multi-degree-of-freedom attitudes for each part of the fuselage panels during the panel assembly process. Adjustment and positioning, support the precise alignment of the fuselage panels, and ensure the high-precision and flexible positioning requirements of the fuselage panels

Embodiment Construction

[0034] Method example:

[0035] (1) Position and adjust the posture of the lower panel of the fuselage. After the lower wall plate is removed from the component assembly frame, use the lifting device to place the lower wall plate of the fuselage on the shape-preserving transport vehicle, so that the outer shape of the lower wall plate closely fits the inner surface of the shape-safe clamping plate, and along the X direction Transport the lower wall plate to the relevant station of the mobile workbench, and use the driving hand wheel to adjust the Z-direction height of the external clamping plate to prepare for the introduction of the lower wall plate positioner. After the lower wall panel enters the assembly workbench station, drive the upper base and the lower base of the four lower wall panel positioners to adjust the positioners in the Y and X directions respectively, and drive the telescopic columns of each positioner to adjust the height in the Z direction. Make the ball...

Abstract

The invention provides a method and a device for folding and flexibly positioning a body wallboard. Due to the method and the tool for folding and flexibly positioning the body wallboard, lots of special clamping boards are not needed and good flexibility is achieved; a positioner clamping mechanism can be adsorbed on a positioning support surface of the wallboard, so that six-freedom-degree and multi-pose regulation of the body wallboard can be achieved; laser trackers distributed on a first layer of working table, a second layer of working table and a third layer of working table can feed back assembling information at real time, thus drastically improving assembly accuracy; the body wallboard is fixed by the adsorption positioning mechanism, thus being simple in assembly and disassembly, reducing manual operation and improving assembly efficiency; and in addition, the method and the device have good generality, so that the method and the device can be suitable for folding process of body wallboard structures with different sizes and satisfy folding requirement of various body wallboards.

Description

technical field [0001] The invention belongs to the technical field of digitized and flexible assembly of aircraft components, and relates to a positioning method and equipment for fitting fuselage panels, which are used for clamping, attitude adjustment and positioning of each part of the panels during the fitting process of fuselage panels. Background technique [0002] With the increasing application of digital technology in the aircraft manufacturing process, modern aircraft manufacturers have put forward high-quality, high-efficiency, high-flexibility and low-cost requirements for aircraft assembly technology. The flexibility of aircraft assembly process has become the current domestic and foreign aircraft A major trend in the field of assembly. [0003] Aircraft fuselage panel components have the characteristics of large structural size, low rigidity, and high requirements for manufacturing and assembly precision. At present, in the assembly process of wall panel comp...
