Technical Field

The invention relates to an ultrasonic electrolysis combined machining device, in particular to a rotary ultrasonic electrolysis combined machining device for a metal matrix composite material.

Background

With the progress of science and technology, the requirements for machining products in mechanical engineering are increasingly strict, and the machining precision and the surface quality of mechanical products become one of important marks for measuring the overall level of the manufacturing industry of a country. The metal matrix composite material is widely applied to industrial production due to a series of excellent performances of high strength, high temperature resistance, wear resistance and the like. Because the metal matrix composite contains reinforcing materials such as particles, whiskers, short fibers and the like with high strength and high hardness, the traditional processing method has high processing difficulty. Since the electrolytic machining has no cutting force and cutting heat during the machining process, deformation and residual stress, work hardening, burrs, flashes and the like caused by the action are not generated, and lower surface roughness and higher machining precision can be achieved. In addition, the electrolytic machining cost is low, and the machining efficiency is high. The ultrasonic vibration is added to change the condition of electrolytic etching, the polarization of the electrode can be reduced by optimizing the amplitude parameter, and the surface quality after ultrasonic electrolytic combined machining is obviously better than that of single pulse current electrolytic machining.

The X-axis ball screw sliding table, the Y-axis ball screw sliding table and the Z-axis ball screw sliding table are used for providing linear feeding in three directions, the servo motor drives the high-speed sliding ring, the inner sleeve, the energy converter and the amplitude transformer to rotate through belt transmission, and meanwhile, the energy converter converts power frequency alternating current electric energy generated by the ultrasonic generator into ultrasonic frequency electric oscillation with certain power output and enables the amplitude of the front section of the ultrasonic frequency electric oscillation to be amplified through the amplitude transformer so as to drive the end face of the electrolytic tool to perform ultrasonic vibration. When the electrolytic reaction device is used for processing, a workpiece is connected with the anode (anode) of a direct current power supply, a tool is connected with the cathode (cathode) of the direct current power supply, and the tool electrode slowly feeds the workpiece to keep a small gap between two stages. The electrolyte pump prevents impurities from being generated on the tool by continuously replacing the electrolyte so that the electrolysis products in the reaction tank are continuously filtered until the surface of the workpiece is formed into a shape basically similar to the surface of the tool.
