Integrated ultrasonic longitudinal-torsion composite turning tool suitable for difficult-to-machine material

Abstract

The invention discloses an integrated ultrasonic longitudinal-torsion composite turning tool suitable for a difficult-to-machine material. The tool comprises a tool body, the front end of the tool body is connected with a tool head, the tool head is of a wedge-shaped structure, and the front end of the tool head is provided with a machine clamping blade. According to the tool, a screw is used forfixing the tool on a tool rest of a lathe turntable, the signal of an ultrasonic generator is input into a transducer assembly through an aviation plug, so that a certain rule of high-frequency vibration is generated, then a tool nose is driven to generate longitudinal torsion amplitude, and ultrasonic turning is realized; and the whole device is small in volume, easy to operate, disassemble or assemble is convenient, and machining precision is high compared with traditional turning, moreover, a machining procedure is reduced, the machining efficiency is improved, and meanwhile, the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of ultra-precision cutting, and in particular relates to an integrated ultrasonic longitudinal-torsion compound turning tool suitable for difficult-to-machine materials. Background technique [0002] Ultrasonic vibration machining is a processing technology formed by applying high-frequency vibration to the tool or workpiece on the basis of ordinary cutting, grinding, drilling and other processing methods. Compared with ordinary cutting, grinding, and drilling processing methods, ultrasonic vibration processing can reduce the cutting force and cutting heat in the processing process, reduce the amount of tool wear, and improve the quality of the processed surface. It is widely used in hard and brittle materials, high-strength steel , hard alloy, titanium alloy, carbon fiber composite materials and other difficult-to-machine materials. With the development of modern processing technology and the popularizatio...

Problems solved by technology

With the development of modern processing technology and the popularization of numerical control technology, the requirements for high precision and high surface quality of parts are getting higher and higher. At the same time, shaft parts occupy a large proportion in manufacturing technology, and the existing ultrasonic The turning tool can only achieve a single longitudinal vibration or apply ultrasonic vibration in two directions to achieve longitudinal torsional vibration. The precision of the former machined parts cannot meet the requirements, and the latter has a complex structure and requires two sets of ultrasonic devices. It is also necessary to calculate the appropriate The phase difference of the vertical button can theoretically guarantee the realization of the composite vibration of the longitudinal button. In addition, this kind of composite vibration device of the longitudinal button requires high precision in installation, the installation steps are complicated, and it is not easy to debug. difficulty
