Compensation method for space relative pose error of aircraft panel horizontal automatic drilling and riveting machine combined 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.
