Radial ultrasonic vibration auxiliary cutting device

Abstract

The invention discloses a radial ultrasonic vibration auxiliary cutting device, comprising: a base plate 1 and a base plate 2; the base plate 1 is fixedly connected to the base plate 2 through a front support block and a rear support block; The bolt is also fixedly connected with a fixed block; the fastening bolt is used to set a crossbeam in the groove of the fixed block; the crossbeam and the pad are arranged on a center line correspondingly; the pad has a guide rail, and the slider slides on the guide rail; The end is fixed with a cover plate through a double-headed stud; the workpiece is placed on the slider and positioned with the cover plate; the front bracket is fixed with bolts on the beam, and a hole for the horn to pass is formed between the front bracket and the beam; A rear bracket is fixedly connected to the beam with bolts, and the rear bracket fixes the transducer on the beam; the transducer is connected with the horn, and the end of the horn is fixedly connected with a workpiece. It realizes radial ultrasonic vibration assisted cutting and measurement of cutting force during processing, and is convenient in design, easy in processing, and easy in assembly and disassembly.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic vibration processing, in particular to a radial ultrasonic vibration assisted cutting device. Background technique [0002] With the development of aerospace, national defense, modern medicine and bioengineering technology, there are more and more demands for miniaturization, miniaturization equipment and micro-sized parts, and the requirements for shape accuracy, dimensional accuracy and surface quality are extremely high. Manufacturing technology has brought severe challenges. The research and development of precision machining, ultra-precision micro-machining and nano-machining technology has become an important development direction of modern manufacturing technology. Japanese scholar Junichiro Kumabe was the first to expound the mechanism and application direction of ultrasonic vibration cutting, which laid a theoretical foundation for the research of vibration cutting. Since then, intern...

Problems solved by technology

However, in the research of ultrasonic vibration cutting in the axial and torsional directions, in order to avoid the winding phenomenon of the ultrasonic vibration device during rotation, a collector ring or carbon brush is required to power the transducer, and a large modification of the drilling machine is required , so the structure is complex, resulting in inconvenient disassembly and assembly of the device and high cost
