Background technology
Axial workpiece is a modal part in all kinds of mechanical means, also is vital part.Continuous development along with science and technology; Request for utilization to many equipment also improves constantly; As usually be operated in high temperature, high pressure, high speed and the severe environment, thereby the material of the axial workpiece that uses in these equipment, working accuracy, surface quality etc. are also just had higher requirement.In order to adapt to above-mentioned working conditions; Axial workpiece in these equipment need adopt some to have the made of premium properties usually; Like superalloy, stainless steel, titanium alloy, ultrahigh-strength steel etc.; And the machinability of these materials is relatively poor, belongs to difficult-to-machine material, adopt traditional diamond-making techniques such as turning processing, ground finish, machinery polishing processing to the difficult-to-machine material axial workpiece carry out slightly, essence or polishing processing are still very difficult under many circumstances or be difficult to satisfy the processing quality requirement.Electrochemical machining is that the principle of utilizing metal in electrolytic solution, to produce anode dissolution removes metallic substance, it have tool cathode lossless, do not have macroscopical cutting force, the suitable various cutting-resistant metal material parts of processing and thin-wall part, advantage such as working (machining) efficiency is high, surface quality is good.Thereby electrochemical Machining Technology combined with the numerical control turning processing technology and the electrolysis Vehicle Processing technology that forms will be one of effective way that solves the difficult-to-machine material Machining of Shaft-type Parts.Electrolysis vehicle tool cathode is the instrument that carries out the electrolysis Vehicle Processing, is one of key of equipment.Current electrolysis turning processing is mainly used in the polishing processing of axle type part; Used negative electrode is " external spraying type " tool cathode that gabarit is similar to lathe tool; Add man-hour electrolytic solution and the electrolytic solution of certain pressure is ejected into process zone by special electrolytic solution shower nozzle; Increase the complexity of equipment, also be difficult for guaranteeing the uniform and stable of electrolytic solution flow field.
Summary of the invention
The deficiency that above-mentioned in order to overcome " external spraying type " tool cathode exists; The tool cathode that electrolysis Vehicle Processing that the present invention provides a kind of " internal spray " is used; It is characterized in that electrolytic solution is ejected into process zone via the tool cathode internal passages; Remove manufacturing and designing of special electrolytic solution shower nozzle from, can guarantee the uniform and stable of electrolytic solution flow field through the inner electrolyte channel of appropriate design tool cathode simultaneously.
Technical scheme of the present invention is:
The tool cathode that a kind of electrolysis Vehicle Processing is used; Comprise tubular type cathode base 2, fixed cavity spare 3, movable cavity spare 6, it is characterized in that movable cavity spare 6 is through the side direction reference plane 10 on it, level reference 11 match with side direction reference plane 14, level reference 15 on the fixed cavity spare 3 formation electrolyte channel inner chamber 5 and electrolyte outlet 8; The movable cavity spare 6 and the fixed cavity spare 3 that match together are installed in the cathode base 2, and fixed cavity spare 3 is fixedly connected by bolt 1 with cathode base 2, and movable cavity spare 6 is pressed on the fixed cavity spare 3 by bolt 7.
Described movable cavity spare 6 position with respect to fixed cavity spare 3 in cathode base 2 can be transferred along the axis direction of tubular type cathode base 2; When movable cavity spare 6 is transferred outside cathode base; It is big that the electrolyte outlet width becomes; When movable cavity spare 6 was transferred inside cathode base, the electrolyte outlet width diminished, thereby reached the flow velocity that control gets into process zone electrolytic solution.
