Control system applied to multipoint array flexible jig, and control method of control system

Abstract

The embodiment of the invention provides a control system applied to a multipoint array flexible jig, and a control method of the control system. The system comprises a moving adjusting unit, an emulation server and a multi-axis controller, wherein the moving adjusting unit obtains positions of a plurality of jig positioning units on coordinates of the jig relative to a coordinate origin; the emulation server determines the position adjustment amount of each jig positioning unit in the plurality of jig positioning units according to the positions of the plurality of jig positioning units on the coordinates relative to the coordinate origin, and determines a control file describing the position adjustment sequence of each jig positioning unit; the multi-axis controller sends control commands to the moving adjusting unit according to the position adjustment amount and the control file of each jig positioning unit; the moving adjusting unit adjusts the position of each jig positioning unit on the coordinate according to the control commands. According to the scheme, the positioning of the plurality of jig positioning units is realized through one moving adjusting unit, so that the cost of the control system is reduced, and meanwhile the wiring complexity and the size of the control system are reduced.

Description

technical field [0001] The invention relates to the technical field of aircraft digital assembly, in particular to a control system and a control method applied to multi-point array flexible tooling. 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. For example, in 1990, Rohr Industries, Inc. 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 flexible tooling system POGO flexible tooling based on POGO units system has been applied to production by Boeing and many other aircraft manufacturers. In 2004, Spain's M.Torres company developed its own aircraft flexible assembly tools, and a large number of them were used in actual pro...

AI Technical Summary

Problems solved by technology

However, the defect of this multi-axis flexible clamping system is that each bent frame and saddle has an independent motor drive device, which leads to the following problems: 1. There are too many independent axes, which causes great damage to the CNC system. Burden; 2. Due to the existence of their respective motor drive devices, the bent frame and the saddle are both large in size, resulting in a relatively large shortest distance between the two support points, which is not conducive to the support of the concentrated part of the workpiece during processing

[0004] In the digital assembly of modern aircraft, there are more and more large parts. When dot matrix tooling is used for assembly, a large number of POGO columns or positioning units are required for support. Based on the above-mentioned each POGO column (tooling positioning unit) with a set The conventional method of independent adjustment of the drive system will greatly increase the number of drives and motors, will greatly increase the cost of the CNC drive system, and will also increase the wiring complexity of the CNC drive system and the volume of the CNC drive system
