Group hole tube electrode electrolytic drilling and grinding integrated processing device and system

Abstract

The electrolytic drilling and grinding integrated processing device and system for group-hole tube electrodes disclosed in this application include: an electrolyte box, a spindle, and several sleeve electrode assemblies; the first end of the spindle passes through the top of the electrolyte box, and the second end of the spindle The two ends are arranged inside the electrolyte box, and the second end of the main shaft is fixed with the first gear; the tube electrode assembly includes a manipulator, an electrolyte delivery tube, a tube electrode and a conductive ring; the manipulator passes through and is fixedly connected to the electrolyte box. At the bottom, one end of the manipulator is provided with a second gear, and the second gears mesh with the first gear respectively; the electrolyte delivery pipe runs through the manipulator, and the electrolyte delivery pipe connects the electrolyte tank and the tube electrode; one end of the tube electrode is fixedly connected to the other end of the manipulator. At one end, a diamond abrasive layer is set on the outer wall of the middle and lower part of the tube electrode; the conductive ring is fixedly set on the end of the tube electrode close to the manipulator. It can process several small or deep small group holes with smooth surface at one time, which greatly improves the precision and efficiency of group hole processing.

Description

technical field [0001] The present application relates to the technical field of small hole or deep small hole processing, and in particular to an integrated processing device and system for electrolytic drilling and grinding of group hole tube electrodes. Background technique [0002] With the continuous development of science and technology, no matter in aerospace, shipbuilding, or automobile manufacturing, the requirements for small holes or small deep holes on various mechanical structural parts are rapidly increasing. For the processing of small holes or deep and small group holes, not only is there an increasingly miniaturized requirement, but the surface quality and precision of the holes are also continuously improved. At present, there are engine housings, aircraft housings, turbine blades, etc. that have a huge demand for processing small holes or deep small group holes. Due to the different array distribution and huge number of these group holes, higher processing...

Problems solved by technology

However, this method is only suitable for the processing of rectangular distributed array group holes. For arc-shaped array group holes or other more complex array group holes, it is impossible to design effective and simple electrode clamps for assembly and processing, which limits the wide application of electrolytic machining. development of
