Abstract

An aircraft structure manufacturing device is provided with: a jig supporting a component of an aircraft structure; a plurality of raising/lowering stands; and a control unit for controlling positions of support parts of the raising/lowering stands. The control unit includes: an input unit inputting position information for a movement destination of a reference point provided to the component; a storage unit storing, in advance, master data, which is the relationship for position information of the support parts of respective raising/lowering stands corresponding to the position information for the movement destination; a unit position information acquisition unit acquiring position information for the support part of each of the raising/lowering stands, based on the master data and the position information for the movement destination; and the movement command unit for simultaneously moving the support parts of a plurality of raising/lowering stands.

First claim

The invention claimed is:

1. An aircraft structure manufacturing device comprising: a jig configured to support components of an aircraft structure; a plurality of raising/lowering stands arranged apart from each other in a horizontal direction, the plurality of raising/lowering stands including support parts being movable in a state in which the jig is supported; and a control unit configured to control positions of the support parts of the plurality of raising/lowering stands on one virtual orthogonal coordinate system, wherein the control unit includes: an input unit configured to input position information for a movement destination for moving a reference point provided on the components of the aircraft structure; a storage unit configured to store, in advance, master data, which is a relationship for the position information for the movement destination and position information for the support parts of the plurality of raising/lowering stands; a unit position information acquisition unit configured to acquire the position information for the support parts of the plurality of raising/lowering stands, based on the position information for the movement destination input and the master data stored in the storage unit; and a movement command unit configured to simultaneously move the support parts of the plurality of raising/lowering stands, based on the position information for the support parts acquired by the unit position information acquisition unit, wherein the components include an upper panel, a lower panel, a rear spar, and a front spar, wherein the plurality of raising/lowering stands includes upper raising/lowering stands and lower raising/lowering stands which are configured to position the upper panel and the lower panel to the rear spar and the front spar, and wherein the control unit is configured to control the positions of the support parts of the plurality of raising/lowering stands so as to be simultaneously moved by different amounts of movement by a single input to the input unit, and to control and limit an operation of the upper raising/lowering stands and the lower raising/lowering stands so as not to operate, when position information of the reference points of the components of the aircraft structure and position information of the master data do not match within a range of a composite image comprising two lines in a vertical direction and two lines in the horizontal direction composed of the master data.

2. The aircraft structure manufacturing device according to claim 1 , comprising: an imaging unit configured to acquire an image of the reference point; a display unit configured to display an image acquired by the imaging unit and a preset marking, and a composite image generation unit configured to output gap information derived from the position information of the reference points of the upper panel and the lower panel acquired by the imaging unit, and the position information of the master data to the input unit.
