Provided is an axial
ultrasonic vibration drilling device fixed by a lathe
carriage. The axial
ultrasonic vibration drilling device fixed by the lathe
carriage comprises a
drill, an amplitude-change pole, a
transducer, a beam hanging type fixed device and an
ultrasonic generator electrically connected to the
transducer. The beam hanging type fixed device comprises a hanging beam fixed on the lathe
carriage and a front pressing plate and a rear pressing plate, wherein the front pressing plate and the rear pressing plate are fixedly connected to the hanging beam, the front pressing plate fixes the front end of the amplitude-change pole, the rear pressing plate fixes the
transducer, a fixed pressing plate fixes the middle part of the amplitude-change pole, and the front pressing plate, the rear pressing plate and the fixed pressing plate are all divided into upper and lower two parts and are assembled through bolts. Compared with a drilling device achieved on a drilling
machine, there is no need to conduct any special refit on a
machine tool; in addition, a method of workpiece revolution is adopted, there is no need to use
assembly units such as a ring manifold or a carbon
brush, thus the structure is simplified, the cost is saved, and the axial
ultrasonic vibration drilling device fixed by the lathe carriage is convenient to disassemble and assemble and is beneficial to a proceeding of ultrasonic vibration drilling.
