Axial ultrasonic vibration drilling device fixed by lathe carriage

Abstract

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.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of machining, and in particular relates to an axial ultrasonic vibration drilling device. [0003] Background technique: [0004] In the field of mechanical manufacturing, various difficult-to-machine materials are increasingly widely used, and the number of micro-holes increases, which makes the processing of holes more and more difficult. In addition, the shape of workpieces is becoming more and more complex, which affects surface roughness, precision and certain The standards that need to be met for special requirements are getting higher and higher, which puts forward higher requirements for machining technology. Due to the problems of high drilling force, high drilling temperature and difficult chip removal in the traditional drilling process, it is easy to cause severe drill wear and low drill life, which reduces the drilling efficiency and increases the processing cost. Therefore, traditional ...

Problems solved by technology

[0005] However, most of the current research is carried out on the drilling machine. Since the drill bit and the ultrasonic vibration device rotate with the spindle of the drilling machine, in order to avoid the winding phenomenon of the ultrasonic vibration device during rotation, a collector ring or carbon brush is required to convert the energy in the ultrasonic vibration device. The power supply of the device, and the drilling machine needs to be greatly modified, so the structure is complex, resulting in inconvenient disassembly and assembly of the device, and the cost is high
