Abstract

The invention provides a single excitation three-dimensional ultrasonic ellipse turning device. The invention includes: an ultrasonic power supply, a device housing and an ultrasonic elliptical vibration cutting unit fixed therein, the ultrasonic power supply is connected to the device housing, the device housing is fixed on the workbench of the machine tool, and the ultrasonic elliptical vibration The cutting unit includes an input end fixed on the device housing, an output end connected to the cutter, and a plurality of vibration-transmitting rods connected between the input end and the output end. The structural properties of the plurality of vibration-transmitting rods are different, so that each There is a phase difference between the phase vibrations, thereby outputting a three-dimensional elliptical trajectory. The device has the characteristics of simple structure, small processing interference, high cutting efficiency, adjustable three-dimensional vibration track of the cutter, strong applicability and the like.

Description

technical field [0001] The invention relates to the field of vibration cutting processing, in particular to a single-excitation three-dimensional ultrasonic ellipse turning device. Background technique [0002] Compared with traditional processing methods, ultrasonic elliptical vibration processing technology has the characteristics of more thorough separation of workpiece and tool, and can also realize the characteristics of "friction force reversal" and "variable angle cutting" in the cutting process, thereby effectively reducing cutting It is easier to obtain better surface processing quality, so it is widely used in precision ultra-precision machining of various difficult-to-machine materials. [0003] In order to realize "completely separated" vibration cutting, the cutting speed should be lower than the critical cutting speed, and the critical cutting speed is proportional to the amplitude in the direction of cutting speed. Therefore, increasing the amplitude in the di...
