Problems solved by technology

[0002] In the traditional aircraft assembly mode, rigid special working ladders are mainly used, and the working ladders and aircraft products are in a "one-to-one" mode, that is, the assembly of an aircraft product corresponds to a set of rigid platforms. This assembly mode leads to special working ladders. The number of manufactures is large, the reuse rate of working ladders is low, the production cycle of aircraft assembly is long, and the storage area of ​​working ladders is large

Embodiment

[0039] Taking the assembly of the fuselage section in a passenger aircraft as an example, the fuselage section is transported to the work area by an AGV.

[0040] First, determine the digital model of the AGV car and the fuselage section.

[0041] Then, under the positional reconfiguration adjustment module of the program system, input the digital model of the AGV car and the fuselage section, and set the coordinates of the digital model to make it reach the theoretical position, and set the working area and working method.

[0042] Secondly, the simulation analysis and verification of the arbitrary setting of the working ladder is carried out, and the influence of interference and collision is eliminated according to the simulation results, and the control system generates the numerical control code according to the simulation results.

[0043] Finally, the fuselage barrel section is transported to the designated work area by the AGV vehicle, and the AGV vehicle is fixed on t...

Abstract

The invention discloses a modularized intelligent reconstruction general work stair platform having a plurality of liftable work stairs. A work area for airplane assembling is enclosed by the plurality of work stairs. The modularized intelligent reconstruction general work stair platform is characterized in that each work stair is a shearing hydraulic elevating work stair; a buried-in groove is arranged on the ground; a pedestal of the work stairs is fixed in the buried-in groove; when expansion amount of the work stairs at a non-work state is zero, the stair platform surfaces of the work stairs are in a seamless connection to form a plane; and the plane is on the same level as the work area ground. Space can be fully utilized by the use of the work stair platform, so use area of a factory plant is increased and low cost and convenience can be achieved for airplane assembling; relative reconstructions can be achieved based on various products by the use of the modularized general work stair platform, so an assembling demand for various reconstructions via one work stair platform can be achieved; and numbers of specific work stairs can be reduced, so manufacturing cost can be lowered.

Description

technical field [0001] The invention provides a modular intelligent reconfigurable universal working platform for aircraft assembly, which is used for rapid reconfiguration of working platforms for products of different configurations under a new transfer mode. Background technique [0002] In the traditional aircraft assembly mode, rigid special working ladders are mainly used, and the working ladders and aircraft products are in a "one-to-one" mode, that is, the assembly of an aircraft product corresponds to a set of rigid platforms. This assembly mode leads to special working ladders. The manufacturing quantity is large, the reuse rate of the working ladder is low, the aircraft assembly production cycle is long, and the working ladder storage occupies a large area. Under the background that the digital assembly mode of aircraft is gradually replacing manual assembly, new equipment and technologies such as flexible tooling, digital mobile docking, and frameless assembly co...
