Abstract

The invention discloses a multi-functional ultrasonic vibration cutting mechanism comprising an ultrasonic signal source, a transducer, an amplitude amplifier pole, a vibration tool holder and a tool. The ultrasonic signal source is connected with the transducer through an amplifying circuit; a voltage dividing circuit in series connection with a voltage dividing resistor is in parallel connection on the amplifying circuit; a telescopic movement mechanism is disposed between the vibration tool holder and a connection device of a machine tool provided with the ultrasonic vibration cutting mechanism; the telescopic movement mechanism is controlled by a power plant operating independently; movement direction of the telescopic movement mechanism is perpendicular to that of the amplitude amplifier pole. With the design of the voltage dividing circuit, amplitude magnitude of the tool is adjusted, depth of a cutting tool workpiece is changed, and requirements of different cutting depth are met. With the design of the telescopic movement mechanism operating independently, the tool has two cutting movement performance of linear motion and elliptical motion, and needs of different cutting process are met. Furthermore, the multi-functional ultrasonic vibration cutting mechanism is multi-functional, widely used, applicable to different processing requirements and more practical.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a multifunctional ultrasonic vibration cutting mechanism. Background technique [0002] Diamond knives have the characteristics of high hardness and good thermal conductivity, and can be ground into ultra-precision cutting tools with extremely sharp edges. However, their high chemical affinity with Fe atoms makes graphitization easily occur when cutting ferrous metals, resulting in serious damage. Chemical wear is difficult to apply to ultra-precision cutting of ferrous metals. [0003] Ultrasonic vibration cutting refers to introducing an additional ultrasonic vibration into the original relative motion between the tool and the workpiece, so that the original continuous cutting process becomes regular intermittent cutting. This intermittent cutting can reduce cutting force, cutting temperature, It can significantly reduce tool wear, improve the surface quality of workpieces...
