Abstract

The embodiment of the invention relates to a piezoelectric vibrator array type ultrasonic shot peening strengthening device. The piezoelectric vibrator array type ultrasonic shot peening strengtheningdevice comprises a supporting device, a shot peening chamber, piezoelectric ultrasonic vibrators and a vibration excitation sheet, wherein the supporting device comprises a shot peening chamber clamping plate, a transducer clamping plate, a bottom plate and a supporting rod; the transducer clamping plate is connected with the shot blasting chamber clamping plate and the bottom plate through supporting rods so as to provide sufficient space for mounting of the shot blasting chamber and the piezoelectric ultrasonic vibrators; the output ends of the piezoelectric ultrasonic vibrators extend intothe shot blasting chamber; an vibration excitation sheet is connected to the output ends of the piezoelectric ultrasonic vibrators; and a plurality of shots are laid on the side, far away from the output ends of the piezoelectric ultrasonic vibrators, of the vibration excitation sheet. The piezoelectric ultrasonic vibrators convert an ultrasonic frequency electric oscillation signal input by an ultrasonic power supply into a mechanical vibration signal with the same frequency, and acts on the vibration excitation sheet after the amplitude is amplified; and the vibration excitation sheet vibrates at high frequency to drive the shots to repeatedly impact the surface of a workpiece to be machined, so that the shot blasting quality and the shot blasting efficiency of an ultrasonic shot peening device are improved.
