Abstract
Automatic drilling and riveting system has been widely used in aircraft manufacture field to satisfy the increasing demands of assembly quality. During the automatic riveting process, the riveting-side working head is the key component to perform the action of pressing rivet and its deformation has a great impact on riveting quality. In this paper, firstly, a theoretical model is established to investigate the factors influencing the deformation of riveting-side working head according to its structure and working situation. Then, the FE models with different squeezing displacements and riveting angles are established to analyze the effort of deformation of the riveting-side working head on driven head dimension, interference, and deformation of riveted hole on panels. Lastly, experiments are performed to verify the simulation results. The results show that the deformation of the riveting-side working head has a significant impact on the final riveting quality, and it can be compensated by increasing the riveting displacement.
