Aviation blade air inlet and exhaust edge polishing device and method

The invention discloses an aviation blade air inlet and outlet edge polishing device and method, and relates to the field of surface polishing device.The device comprises a foundation frame, a tensioning mechanism and a driving mechanism, the tensioning mechanism and the driving mechanism are fixed to the foundation frame, a driving wheel is arranged at the output end of the driving mechanism, and a plurality of driven wheels are further rotationally connected to the foundation frame; the air inlet and exhaust edge polishing device further comprises an abrasive belt and an elastic contact arm fixed to the foundation frame, the abrasive belt bypasses the driving wheel, the driven wheels and the elastic contact arm to form an abrasive belt movement device with tensioning force, the air inlet and exhaust edges of the aviation blade are polished through the suspended abrasive belt, the polishing contact area is increased, the polishing pressure intensity is reduced, the over-polishing condition is improved, and t
