采用电解加工可以一次成型,为了保证表面质量,采取反向供液方案,从主轴孔引进的电解液通过分液套进入加工区,由中心孔流出。为了保护零件已加工过的内外圆柱面免受杂散腐蚀,采取内外护套,由于零件的内外柱面尺寸公差较大,将内、外护套设计成开口式,内护套的孔做成内圆锥面,外径按零件内柱面设计,夹紧时由锥面螺钉将内护套涨开,与零件内柱面贴紧,外护套用弹性夹头通过旋动琐紧螺母使其内孔与零件外柱面贴紧。
The use of electrolytic machining can be a molding, in order to ensure the surface quality, to reverse the solution, the introduction of the electrolyte from the spindle hole into the processing zone through the liquid separation, out of the center hole. In order to protect the parts have been machined inside and outside cylindrical surface from stray corrosion, to take the outer sheath, the inner and outer parts of the cylinder size tolerances larger, the inner and outer sheath designed to open, the inner sheath made of holes The inner conical surface and the outer diameter are designed according to the inner cylindrical surface of the part. When the inner surface of the inner conical surface is clamped, the inner sheath is opened by the conical surface screw and closely clamped with the inner cylindrical surface of the inner part of the outer sheath. The inner hole and the outer part of the cylinder close together.
