Aircraft main landing gear hatch door assembling coordinate platform

Abstract

The invention belongs to the technical field of aircraft assembling, and relates to an aircraft main landing gear hatch door assembling coordinate platform which comprises a foundation, a main frame, hatch door intersection positioning assemblies, hatch door appearance detecting boards, main landing gear fairing process fake frames and a tension belt assembly. The main frame is installed on the foundation. The hatch door intersection positioning assemblies, the hatch door appearance detecting boards, the main landing gear fairing process fake frames and the tensioning belt assembly are installed on the main frame. The positioning coordinates of the hatch door intersection positioning assemblies are the same as the assembling interaction coordinates of an aircraft actual hatch door. The inner shape of the hatch door appearance detecting boards is the same as the theoretical appearance of the hatch door, and the inner shape of the hatch door appearance detecting boards is larger than the theoretical appearance of the hatch door. The two ends of the coordinate platform are provided with the main landing gear fairing process fake frames which are totally the same with aircraft main landing frame fairing lap joint frames in appearance. By means of the aircraft main landing gear hatch door assembling coordinate platform, the production cost and assembly risk are reduced, actual assembling workloads are reduced, and the development cycle is shortened.

Description

technical field [0001] The invention belongs to the technical field of aircraft assembly, and relates to an assembly coordination platform for an aircraft main landing gear hatch. Background technique [0002] Aircraft doors generally have strict functional and reliability requirements, especially the opening and closing of the doors, as well as the accuracy and interchangeability of the outer edge. As a result, the manufacture and installation of the doors has always been a difficult point in the field of aircraft assembly technology. For the installation of the hatch, there are structural features such as rotating hinges and fixed locking devices. In order to ensure the strict coaxiality and position requirements of the rotating hinges and fixed locking devices, when assembling the hatch, it is often necessary to use assembly fixtures to achieve. These fixtures can ensure the concentricity and position of the rotary hinge and fixed locking device of a single hatch through ...

AI Technical Summary

Problems solved by technology

In order to ensure the functional and reliability requirements of the door assembly, the existing process methods often spend huge sums of money on standard samples and standard tooling such as gauges to ensure the coordination of the door, resulting in a significant increase in aircraft development costs. Moreover, the coordination of samples and gauges, as well as the development and management of standard tooling will greatly increase the overall development cycle of the aircraft, etc.

[0003] At the same time, for the assembly of multiple hatches, only the assembly coordination of a single hatch is satisfied, and the assembly coordination among multiple hatches cannot be guaranteed at the same time.

During the actual installation process of the hatch, there are often assembly risks such as a large shape difference between the hatches, uneven gaps between the hatches, and interference between the hatches.

The emergence of these problems during the installation process is very difficult to deal with, which will reduce the quality of the aircraft to a certain extent, and increase the cost and cycle of aircraft development and delivery
