The inner ring and blade of an aero-engine fan rectifier are connected by interference flaring pins,after which the flaring pins are expanded.Assembling the flaring pins in a narrow space is a difficult process.Aiming at the technical difficulties of assembling interference flaring pins in a narrow space of an aero-engine fan rectifier,the installation process of interference flaring pins in a narrow space is studied.Flaring technology research and flaring effect detection technology research.The developed special flaring pin installation tool avoids the risk of rebound and cracking caused by the thin wall of the deformed part of the flaring pin and large elastic modulus.The developed special flaring tool overcomes the flaring problem of the flaring pin in a small space.The developed special measuring tool solves the problem that the diameter cannot be measured after the flaring in a small space by converting the diameter into an internal diameter measurement method.The technological breakthrough of overcrowding flaring pin assembly was realized.
