Abstract

The invention discloses an automatic drill-rivet processing data deviation measurement and compensation method. The method comprises the steps that a wireless Bluetooth measuring device is fixed on an automatic drill-rivet device mechanism; for a drill-rivet characteristic point position, the circumferential position angle of both sides of a stringer web is measured to generate a deviation data file; and through off-line data compensation, a final drill-rivet processing procedure is generated. The method has the advantages of high measurement precision, high measurement efficiency and non-destructive measurement, and carries out automatic deviation compensation in an off-line mode. The compensation accuracy is ensured. Processing deviation caused by manual assembly is solved.

Description

technical field [0001] The invention relates to the technical field of automatic drilling, riveting, processing and assembly of launch vehicle cabins, in particular to an automatic drilling and riveting data deviation measurement and compensation method, which can realize non-destructive measurement and off-line automatic compensation of circumferential deviations of cabin stringers. Background technique [0002] At present, the developed countries in the aerospace industry in the world have widely used automatic drilling and riveting technology. Decades of application of foreign riveting assembly technology shows that the assembly efficiency of automatic drilling and riveting machine is at least 10 times higher than that of manual riveting assembly, and it can save installation costs and improve working conditions. More importantly, it can ensure installation quality and greatly reduce manpower. defects caused by factors. The use of automatic drilling and riveting machines...
