Ultrasonic vibration assisted electrolysis matrix oblique square hole processing system and method

Abstract

The invention provides an ultrasonic vibration assisted electrolysis matrix oblique square hole processing system and a method. The ultrasonic vibration assisted electrolysis matrix oblique square hole processing system includes a three-dimensional motion mechanism, a control device, a transition device, a workbench, an ultrasonic vibration device and a hollow electric spindle. The three-dimensional movement can drive the hollow electric spindle to move in a three-dimensional mode relative to the worktable, the ultrasonic vibration device can apply ultrasonic cavitation to the hollow electricspindle during the process of supplying electrolyte by an inner hole of the hollow electric spindle, the transition device is arranged between the hollow electric spindle and an electrode assembly, the transition device includes a plurality of gear shafts and dynamic sealing rings which revolve around the hollow electric spindle and can rotate, and the dynamic sealing rings can connect the ends ofthe gear shafts and tube electrodes. The tube electrodes and conducting rings are all synergistically driven by the transition device and a pulsed power supply, the workbench is used to carry components to be processed, and the angle is variable. By adjusting the electrolytic grinding current, ultrasonic vibration frequency, amplitude, rotating speed of the hollow electric spindle and the angle of the workbench, precision machining of an oblique square hole is realized.

Description

technical field [0001] The disclosure belongs to the technical field of deep holes, mold cavities and electrolytic grinding, and in particular relates to an ultrasonic vibration-assisted electrolytic matrix oblique hole processing system and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the continuous development of the manufacturing industry, especially the continuous development of the aerospace manufacturing industry, the wide application of high-strength, high-temperature-resistant, wear-resistant and other difficult-to-machine materials, the requirements for processing small holes or deep small group holes on various mechanical structural parts is rapidly improving. For the processing of oblique small holes or small deep small group holes, not only are there more and more miniaturization requirements, but also the sur...
