Flexible tool equipment intelligent control system of aircraft

Abstract

The invention provides a flexible tool equipment intelligent control system of an aircraft, which comprises a coordinate extracting system, a decision control system and an executing mechanism, wherein the coordinate extracting system is used for carrying out curve digital modeling on a workpiece to be processed, extracting the support point coordinate information of the workpiecce and generatingand transmitting a workpiece coordinate information file to the decision control system; and the decision control system is used for planning and deciding the action of the executing mechanism according to the workpiece coordinate information file and generating and transmitting a corresponding control command to the executing mechanism. The invention provides a flexible tool equipment intelligent control system for realizing clamping and positioning in the processing of a large curve thin wall part of an aircraft, carries out calculation and control by adopting a high-performance industrial control computer as a core and realizes the synergy movement control on double robots by an intelligent control main board and the reasonable and uniform distribution of all support units on a flexible tool equipment machine tool by the moving operation on all the support units on the flexible tool equipment.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to the technical field of aircraft manufacturing, and more particularly to an intelligent control system for flexible tooling of aircraft, which is used for processing curved thin-walled parts of aircraft. Background technique [0002] In order to solve the processing problems of large thin-walled parts of aircraft, technicians from the United States, Spain and other countries have carried out research work for many years and developed various flexible assembly tool technologies. In 1990, Rohr Industries and Incl of the United States developed a flexible robot work unit for the assembly of fuselage components; from 1994 to 2001, the American CAN Manufacturing System Company developed a POGO flexible tooling system based on POGO units. It has been applied to production by many aircraft manufacturers such as Boeing. In 2004, Spain's M.Torres company developed its own aircraft ...

AI Technical Summary

Problems solved by technology

However, this multi-axis flexible clamping system has some obvious defects, which are mainly manifested in: (1) Each bent frame and saddle has a set of independent motor drive devices, and the number of independent axes is too large, which causes serious problems for the CNC system. (2) Due to the existence of their respective motor drives, the volume of the bent frame and the saddle is large, resulting in a relatively large shortest distance between the two support points, which is not conducive to the concentrated force of the workpiece during processing support
