Problems solved by technology

Therefore, the above-mentioned improved method does not completely get rid of the special pallets. When faced with different shapes of wall panels, different assembly tooling must be developed, and the rich 3D digital and analog information on the design side cannot be used, resulting in increased development costs and manufacturing data. transmission fault

Embodiment Construction

[0033] The aircraft fuselage panel (chord height 180mm) with curvature of length × width × thickness = 4500mm × 1500mm × 4mm is assembled and positioned, and the positioning accuracy is controlled within 0.1mm.

[0034] Method example:

[0035] (1) Establish the three-dimensional model of the column array tooling and the fuselage panel, and set the assembly reference coordinate system in the three-dimensional model of the tooling. According to the structure, shape and size characteristics of the tooling and the 3D model of the fuselage panel, the relative position and attitude of the 3D model of the fuselage panel and the 3D model of the tooling are adjusted in the 3D CAD assembly environment, so that the panel is positioned in all positions of the tooling within the positioning range of the point to ensure that the fuselage panel can be successfully installed and positioned on the tooling;

[0036] (2) The positioning method of N-2-1 is adopted (the inner surface of the wall...

Abstract

The invention discloses a method for assembling and positioning a vertical column array type fuselage wall panel and a device thereof. The method comprises the steps of: firstly, establishing a three-dimensional model of a vertical column array type tool and a fuselage wall panel; then, uniformly dividing a positioning region of the wall panel in the three-dimensional model; uniformly arranging positioning points of the wall panel within the range of the wall panel; accurately positioning the model of the wall panel; reading a coordinate; controlling each positioning point of the tool to moveto a specified coordinate; measuring actual coordinate values; computing and generating coordinate compensation values; and controlling for movement. According to the invention, on the basis of completely discarding a template, the wall panel is ensured to be accurately positioned according to a design requirement; and different assembly requirements are satisfied.

Description

technical field [0001] The invention belongs to the field of digital assembling equipment and technology, and relates to a method and equipment for assembling and positioning an aircraft fuselage panel. Background technique [0002] Flexible assembly tooling is a reconfigurable modular and automated assembly tooling system based on a product digital dimension coordination system. Its purpose is to eliminate the need to design and manufacture traditional assembly frames / fixtures dedicated to the assembly of various products, thereby reducing tooling manufacturing costs. , shorten the tooling preparation cycle, and greatly improve the assembly productivity. Its main feature is that it is based on the digital size transfer system of the product and relies on the digital control system to complete operations such as positioning and clamping for product assembly. [0003] In the current engineering application, the solution for panel positioning is to design a set of special pos...
