In order to improve the accuracy of large-size aircraft ribs assembly location

reduce the deformation of the assembly and finally meet the requirements of the deviation of the ribs spacing in the wing box assembly process

based on the analysis of the assembly positioning requirements and the position uncertainty of the large-size ribs assembly

a kind of rigid assembling technology of dot matrix was proposed. A new set of rigid lattice enhancing tool was designed based on the deformation analysis

which realized the large-size rib-shaped positioning and the multi-degree-of-freedom adjustment of the positioner. It reduces the deformation of the ribs and ensures the ribs spacing

which is of guiding value for the actual assembly of the large-size aircraft ribs.
