The invention relates to an ultrasonic combined electrical discharge machining technology, in particular to an ultrasonic-assisted electrical discharge machining device. The ultrasonic-assisted electrical discharge machining device comprises a work table, a working liquid tank, a sleeve, an end cover, an amplitude-change rod, a pre-tightening screw, an ultrasonic transducer, a pre-tightening nut, a fixing nut, a supporting leg and a semi-arc holder, wherein the working liquid tank is fixed in the front of the upper surface of the work table, the back sidewall of the working liquid tank is provided with a through hole penetratingly, the sleeve is positioned on the outer portion of the working liquid tank, a radial boss is arranged on each of the outer front side face and the outer back side face of the sleeve, the front radial boss of the sleeve is connected with the back sidewall of the working liquid tank, a front opening of the sleeve is in butt joint with a back hole orifice of the through hole, the end cover seals a back opening of the sleeve, and the edge of the end cover is connected with the back radial boss of the sleeve. The ultrasonic-assisted electrical discharge machining device solves the problems of structural complexity, difficulty in implementation and poor stability of an existing ultrasonic electrical discharge machining device and is applicable to ultrasonic combined electrical discharge machining.
Description
technical field [0001] The invention relates to an ultrasonic electric discharge composite processing technology, in particular to an ultrasonic auxiliary device for electric discharge processing. Background technique [0002] With the development of production and the advancement of science and technology, new materials with high melting point, high hardness, high strength, high brittleness, high viscosity, high toughness, high purity and other properties are constantly appearing, with various complex structures and special process requirements. There are more and more workpieces, still using mechanical processing methods, sometimes difficult or impossible to process. [0003] The EDM method is a method of processing materials by using the electrocorrosion phenomenon generated during pulse discharge between the two electrodes, because it is not limited by the strength and hardness of the material during processing, and there is no macroscopic force between the workpiece and...
