Airplane engine inlet blade prying robot and method

Abstract

An aero-engine inlet passage blade turning robot and method are disclosed. In the robot, a walking chassis is movably arranged in an aero-engine inlet passage; a front-rear adjustment linear slide rail linkage gear meshing circular arc track turning rod is fixed on the walking chassis to drive the aero-engine blade to reciprocating turning motion; an opening mechanism is arranged on the front-rear adjustment linear slide rail linkage gear meshing circular arc track turning rod to radially tension and position the aero-engine inlet passage blade turning detection robot; a sensor includes a laser radar sensor and a camera unit, which is used for inlet passage internal point cloud and image data acquisition; a portable control terminal analyzes and processes the inlet passage internal point cloud and image information and closed-loop controls the body motion of the aero-engine inlet passage blade turning detection robot; a control handle is connected with the portable control terminal, which converts manual instructions into driving signals to control the motion of the walking chassis, the front-rear adjustment linear slide rail linkage gear meshing circular arc track turning rod and the opening mechanism.
