Embodiment Construction

[0034] This embodiment is a method for flexible assembly of leading edge flaps.

[0035] refer to figure 1 , figure 2 , the leading edge flap components are composed of the following typical structures, 1#-13# rib 1, 1#-3# intersection joint 2, angled beam 3, 1#-2# control joint 4, skin 5, Wherein, two coordinate positioning holes are respectively opened on each wing rib.

[0036] The positioning part of the leading edge flap rib baffle is a "convex"-shaped flat plate structure. The front part of the positioning plate is provided with a rib positioning surface 7, and the two sides of the middle part are provided with reinforcing ribs 10. There are 3 ribs above and below the reinforcing ribs 10. The oval lightening grooves 9 are distributed symmetrically. The rib positioning surface 7 is provided with five coordinate positioning holes 6 distributed in a straight line perpendicular to the central axis of the positioning member, corresponding to the two positioning holes on t...

Abstract

The invention relates to a method for flexibly assembling a leading edge flap. A laser tracker measurement system is used for measuring characteristics of a leading edge flap product, and detecting the accuracy in an assembly process to realize the flexible assembly of the product, and special assembly tools are reduced as many as possible. According to a flexible assembly platform, a movable rib baffle plate positioning part is used for accurately positioning all ribs of the leading edge flap product, positioning parts are not required to be replaced, the positioning accuracy is ensured, and the degree of flexibility is high; and high coordination accuracy is ensured, and the assembly accuracy of the leading edge flap is improved. The method comprises the following steps of: 1, calibration of measurement reference points and establishment of a tool Cartesian coordinate system; 2, tool assembly of a measured workpiece; 3, regulation of an initial position of the measured workpiece; 4, assembly of oblique beam web planes and intersection points thereof; 5, assembly of end part ribs; 6, assembly of other ribs; 7, assembly of a skin; 8, removal of the assembled product; 9, detection of aerodynamic configuration; and 10, analysis on detection data.

Description

technical field [0001] The invention relates to a method for assembling model products, in particular to a method for flexible assembling of leading edge flaps, belonging to the technical field of aircraft wing surface assembly in aviation manufacturing. Background technique [0002] Aircraft leading edge flap components usually adopt a single-spar, multi-rib, metal riveting structure, which is composed of basic parts such as wing ribs, spars, hinges and skins. The traditional leading-edge flap product assembly method is carried out on a special rigid frame based on the transfer of dimensional analog quantities, and the ribs and skins are positioned according to a large number of shape clamps on the frame and special positioning and clamping devices. This method of positioning assembly has the following problems: (1) the jig used for assembly is specially made, which cannot realize the flexible assembly of multiple objects of the leading edge flap product, and the applicabil...
