High-precision flexible coordination assembly method for functional components of carrier rocket cabin section

The invention provides a carrier rocket cabin functional assembly high-precision flexible coordination assembly method. The method comprises the following steps that S1, the installation positions of a laser projector and a laser tracker are determined; s2, establishing a measurement coordinate system; s3, establishing a process model composed of a separation spring support, a guide ring, a front end frame, a rear end frame, a stringer and an explosive bolt box by using three-dimensional modeling software; s4, selecting a positioning reference in the process model created in the step S3; s5, the contour lines of the release spring support and the guide ring are projected to the outer surface of the cabin section through a laser projector for coarse positioning; S6, the guide ring is positioned through an auxiliary tool under the frame; and S7, the laser tracker is used for measuring and aligning the accurate positions of the separation spring support and the guide ring. Dependence of products on tools is redu
