Description

A rapid positioning and installation vehicle for composite structural parts

technical field

The utility model belongs to the technical field of aircraft assembly, in particular to a vehicle for fast positioning and installation of composite material structural parts.

Background technique

Traditional aircraft are mostly semi-monocoque structures, and their structural parts are assembled by riveting aluminum alloy skins, frame edges, and long trusses. The assembly and positioning process and equipment frame design has become mature. However, with the advancement of composite material forming technology, it is widely used in aircraft structures, especially large and even special-shaped structural parts. Due to the differences in structure and material properties between composite material structural parts and aluminum alloy structural parts, it is necessary to use special process equipment for installation after the general assembly of the aircraft.

Due to the large volume, complex shape and much heavier weight than metal structural parts of composite material structural parts, the installation of existing composite material structural parts is to use marking and positioning knots, and install them through special installation car-shaped supporting structural parts. The special installation vehicle fits and supports the shape of the structural parts through the inner type of the pallet, and there is no stable and reliable mechanical connection, which makes it difficult to be stable in the installation vehicle and difficult to install and adjust. Adjusting the posture of structural parts leads to problems such as easy deformation of structural parts, inaccurate positioning, and unstable assembly quality.

Utility model content

The purpose of the utility model is to solve the problem that the original composite material structural member installation vehicle cannot be accurately positioned, and the structural member can be stably and reliably installed and disassembled.

In order to solve the above-mentioned technical problems, the technical solution of the utility model provides a fast positioning and installation vehicle for composite material structural parts, which includes a vehicle frame 1 and a clamping part 2, and several body positioners 3 are pre-installed on the body, and in the clamping The upper end of the part 2 is equipped with several composite function locators 4 corresponding to the body locator 3, the body locator 3 includes a single ear with a hole, and the composite function locator 4 includes a positioning single ear 401, Clamping single ear 402, hoisting single ear 403, base 404, the positioning single ear 401 has a hole matching with the hole of the single ear of the body positioner 3, and the clamping single ear 402 is matched with the hole through the hole The upper end of the clamping part 2 is connected by bolts, the hoisting lug 403 is located on the upper part of the composite function locator 4 and has a hoisting hole, and the base 404 has a threaded hole corresponding to the embedded thread hole on the composite material structure hole.

Compared with the existing installation vehicle, the utility model has the advantages that: the installation vehicle solves the problems of rapid positioning, reliable and stable installation and disassembly of large and special-shaped composite material structural parts in the assembly process of aircraft components, shortens the production and development cycle of aircraft, and improves Ground and outfield maintenance response speed.
