The invention provides a piezoelectric steering engine structure, and relates to the technical field of aerospace aircraft rudder wings. The piezoelectric steering engine structure comprises a steering engine room shell, the bottom end of the steering engine room shell is fixedly connected with a fixing mounting base, the fixing mounting base is used for fixing a rudder wing in the steering engine room shell, the rudder wing comprises a base, a fastening screw, a rudder wing shell, a piezoelectric plate, a torsion spring and a rotating shaft, the rotating shaft is connected to the base through a rotating shaft connecting piece, and the piezoelectric plate is arranged on the rotating shaft connecting piece. The set screw applies acting force to fix the piezoelectric plate, and the rudder wing shell is fixed through cooperation of the rotating shaft and the rotating shaft clamping piece. After the piezoelectric plate is deformed under certain voltage, the rudder wing is pushed to deflect in the rudder wing shell, so that the aim of deflection of the control surface of the steering engine is fulfilled, and the steering engine has the advantages of simple structure, easiness in miniaturization, high response speed, high response precision, high electromechanical coupling coefficient, strong anti-interference capability, light weight, high response speed and the like.
