Abstract

A device is for surface strengthening of a metal plate based ultrasonic vibration is provided. The device includes an ultrasonic vibration tool holder and a cutting tool. The ultrasonic vibration tool holder is internally provided with an ultrasonic transducer and an ultrasonic booster; the ultrasonic transducer is configured to transmit vibration to the ultrasonic booster, the ultrasonic booster is configured to drive longitudinal torsion vibration of the cutting tool; an end of the ultrasonic booster facing towards the cutting tool is provided with an adjustment assembly configured for adjusting a longitudinal torsion angle and a rotation speed. Since the device includes the adjustment assembly, the longitudinal torsion angle and the rotation speed of the device can be adjusted according to different processing requirements, so as to perform ultrasonic vibration extrusion strengthening on surfaces of titanium alloy plates and improve surface integrity including microhardness and residual stress.
