Problems solved by technology

The existing locator is a fixed structure, which is easily disassembled and installed repeatedly, which will easily cause the deformation of the butt truss and increase the labor intensity of the workers. Especially for large aircrafts, the size and weight of the locator are relatively long. become larger, the existing locator structure cannot satisfy the assembly of large aircraft docking girders

Embodiment Construction

[0015] Referring to the accompanying drawings, the positioning device for connecting wing panels to long stringers includes a base 1, a positioning body 2, a clamping assembly 3 and a shape compactor 4. The base 1 is a rigid fixed seat, and the lower part of the fixed seat There is a connection hole 15 fixed to the frame, a rigid connection plate 14 parallel to the positioning body 2 is extended from the upper part of the fixing seat, and two horizontal oblong hole-shaped guide chute 5 are formed on the connection plate, and the positioning body 2 is a rigid base plate on which the clamping assembly 3 and the shape compactor 4 are installed. The clamping assembly includes an upper assembly 6 and a lower assembly 7, and the shape compactor 4 uses a screw screw to tighten the product.

[0016] The wing parts wall plate 12 is fixed on the outer clamping plate 13 of the assembly jig, and the long stringer 11 needs to be fixed on the wall plate 12 by a positioning device for assembl...

Abstract

The invention discloses an aircraft wing wall panel butt joint stringer locating device comprising a base, a locating body, an axis surface locating and clamping assembly and an appearance compressor; a connecting plate of the base is provided with a guide sliding chute in an oblong hole shape, which is used as the guide for the movement of the locating body, and the axis surface locating and clamping assembly and the appearance compressor are respectively fixed on two sides of the locating body. The locating device is capable of accurately locating, clamping a butt joint stringer and conveniently moving so as to be beneficial for assembling a product, putting the product on the shelf and taking down the product from the shelf.

Description

technical field [0001] The application relates to large aircraft assembly tooling, in particular to a positioning and clamping device on the tooling when wing panels and stringers are butt-jointed and assembled. Background technique [0002] Long stringers are important structural reinforcements for aircraft wing panels. They are usually processed by machining and shot blasting. They have the characteristics of hyperbolic shape, long length, large slenderness ratio, wall thickness and heavy weight. [0003] When assembling the wing panel and the butt stringer of the aircraft, the girder and the wing panel of the aircraft are positioned by using the assembly jig and the butt stringer locator. The existing long stringer positioning is to use the shape and end of the long stringer to press the stringer against a specific assembly position of the wing panel through a locator. Most of the existing truss locators are fixed structures, which adopt axial surface stoppers for positi...
