The invention relates to an electrolytic
machining device for a self-guiding bent straight hole and a
processing method thereof. The electrolytic
machining device structurally and mainly comprises a flexible knife
handle and an
electrode, wherein the
electrode is of a blocky shape and is provided with an upper end plane and a lower end plane, and the sides of the electrodes are circular arc transition surfaces; the middle part of the flexible knife
handle is connected with a liquid feeding
pipe in a sliding and
insertion way, and the liquid feeding
pipe is communicated with a through hole in the middle of the
electrode; a pair of movable control bars and a pair of
steering control bars are connected at the two sides of the flexible
handle in the flexible knife handle in a sliding and inserting way, the movable control bars are conductors with electrified electrodes, the respective ends of the two movable control bars are respectively hinged to the centers of the circles of the circular arc transition surfaces, and hinged axes are parallel to each other; the respective certain ends of the
steering control bars are connected with arc-shaped
steering control blocks, and the circular arc ends of the two steering control blocks are respectively propped against the circular arc transition surfaces at the two sides of the electrode. When a hole is formed, the straight hole or bent hole
processing can be realized dependent on the synchronous or asynchronous feeding of the movable control bars and the steering control bars at the two sides of the flexible knife handle; furthermore, the electrolytic
machining device is more convenient to process, easy to control the
processing precision, and better in hole processing quality.
