Single excitation two-dimensional compound vibration ultrasonic deep rolling processing device

The utility model discloses a single excitation two-dimensional compound vibration ultrasonic deep rolling processing device comprising a piezoelectric transducer, which is connected to a supersonic generator by a lead; a first amplitude transformation rod and a second amplitude transformation rod, which are connected to the piezoelectric transducer; a spherical tool, which is connected to the second amplitude transformation rod by a clearance fit with a pin shaft. The first amplitude transformation rod and the second amplitude transformation rod are in a jacking cooperation by an inclined plane, and can be fixed by a locking screw to form a cone-shaped flat plate. The device provided in the utility model is reasonable in design, is simple in structure, and can be fixedly disposed on a cutter rest of a common metal cutting machine tool, therefore the processing range of the machine tool can be expanded, and the two-dimensional compound vibration ultrasonic deep rolling processing can be realized.
