High-frequency longitudinal torsion composite vibration sponge punching workbench and application thereof

The invention relates to a high-frequency longitudinal torsion composite vibration sponge punching workbench and an application thereof. The workbench comprises a base, a horizontal movement mechanism, a fixing frame, a vertical movement mechanism, a supporting frame and a high-frequency longitudinal torsion composite vibration sponge punching device. The high-frequency longitudinal torsion composite vibration sponge punching device comprises an ultrasonic generator, an ultrasonic transducer, at least one stage of amplitude-change pole and a tubular tool. The tubular tool comprises a connector connected with the amplitude-change poles, a tube body with a cavity inside and a cutting edge, wherein one end of the tube body is in threaded connection with the connector; the cutting edge is arranged at the other end of the tube body; and the tube body is provided with a longitudinal torsion composite vibration conversion structure. According to the technical scheme, sponges are punched easily in a high-frequency longitudinal torsion composite vibration mode; horizontal movement of workpieces to be machined is achieved through a horizontal movement mechanism; the punching device can move up and down accurately through the vertical movement mechanism; and by means of the fixing frame, accurate automatic-control punching can be conducted in the specific positions of the workpieces to be machined as needed.
