Micro-texture radial vibration auxiliary electrolytic machining method and device for inner wall of rotary body of thin-wall part

Abstract

The invention relates to a micro-texture radial vibration auxiliary electrolytic machining method for the inner wall of a rotary body of a thin-wall part. The method is characterized in that a tool cathode with a micro-boss texture on the surface and capable of doing radial vibration is connected with a negative electrode of the power supply, the tool cathode is connected with an ultrasonic current generator, a thin-wall rotary body workpiece is connected with a positive electrode of the power supply, and the columnar electrode on the tool cathode is arranged in a linear array mode; an electrolyte enters a reaction area between the tool cathode and the workpiece through a liquid supply pipe; a machine tool spindle drives the tool cathode to horizontally move in the peripheral direction according to a preset trajectory, a certain machining gap is reserved between the workpiece and the columnar electrodes on the tool cathode, the machine tool spindle drives the tool cathode to do autorotation motion, and the tool cathode connected with the ultrasonic current generator is used for constructing an ultrasonic energy field; the electrolyte flowing out at a high speed is sprayed onto theworkpiece to obtain the required machining morphology. The invention further provides an micro-texture radial vibration auxiliary electrolytic machining device for the inner wall of the rotary body ofthe thin-wall part. According to the method and the device, the centering property, the stability, the precision and the efficiency for machining the micro-texture of the inner wall of the rotary body are improved.
