Layout method of central airframe digital assembly of big plane

The invention discloses a layout method of a central airframe digital assembly of a big plane. The central airframe digital assembly layout of the big plane is divided into two stations of a component assembling station and a processing station, and toolings adopt symmetric layout. The toolings to which the component assembling station relates comprise a wallboard positioner, a main starting intersection frame positioner, a laser tracker, a wallboard shape-preserving rack, a main starting intersection frame shape-preserving rack, a process middle wing, a wing body butt joint frame shape-preserving rack, a process floor, an operation desk and portable minitype high-speed hole processing equipment. The toolings to which the processing station relates comprise an airframe positoner, a multi-lattice flexible adsorption tooling, a laser tracker, main starting intersection hole surface processing equipment, an airframe end face and measuring point hole processing equipment, an airframe process joint and an operation desk. In the invention, the central airframe assembly layout is divided into multiple stations, and an advanced digital production line is constructed; the precision and theaccuracy of the central airframe assembly are improved.
