Method for compensating spatial relative position errors of horizontal automatic boring and riveting machine of aircraft panel with temperature factor

Abstract

The invention discloses a method for compensating the spatial relative position errors of a horizontal automatic boring and riveting machine of an aircraft panel with a temperature factor. The method comprises the following steps: analyzing the cooperative working space of two positioning devices in the horizontal automatic boring and riveting machine of the aircraft panel, and partitioning grids reasonably; at different temperatures, using a laser tracker to track and measure the actual relative position errors of the two positioning devices so as to construct a spatial relative position error grid in a certain temperature range, and calculate the error value at any point in the cooperative working space grid at the target temperature through a linear interpolation method and a shape function interpolation method; and according to the master-slave relationship of the two positioning devices, realizing error compensation by the strategy of the spatial relative position error compensation of two cooperative devices by a slave positioning device. By adopting the method, the accuracy of the cooperative work of multiple devices is quickly and effectively enhanced, the hole machining quality in aircraft assembly is improved, and further the overall assembling quality and the assembling efficiency of aircraft components are improved.

Description

technical field [0001] The invention relates to the field of aircraft assembly technology and equipment, in particular to a method for compensating space relative pose error of an aircraft wall plate horizontal automatic drilling and riveting machine combined with temperature factors. Background technique [0002] As an extremely important part of aircraft manufacturing, aircraft assembly determines the final quality, manufacturing cost and delivery cycle of the aircraft to a large extent, and is the key and core technology in the entire aircraft manufacturing process. Since a large number of hole making and fastener connection processes are involved in the aircraft assembly process, the quality and efficiency of hole making and fastener connection will become an important factor affecting the overall assembly quality and efficiency of the aircraft. [0003] The horizontal automatic drilling and riveting machine for aircraft siding is an important equipment for hole making a...
