The present invention involves an island -shaped alien conveyor electrolytic processing device and electrolytic processing method, including: conductive cathode, processing water cover and fixed set, processing cathode in a large hollow structure; processing water suits are located on the cathode of the processing and can be along the place along the placeThe length of the length of the processing cathode moves, the inner wall of the processing water cover is formed with the first inner cavity together with the part of the processing parts;; The fixed sleeve is set on the cathode of the processing, which forms a second internal cavity in the fixed case.There is a piston body in the second cavity, which is connected to the piston rod in the piston body. One end of the piston rod is set in the second inner cavity.The present invention realizes the tightness of the reflux water cover, and solves the problem of no place to fix the water sleeve in the densely distributed part of the machining site.
Description
technical field [0001] The invention relates to the technical field of electrolytic machining, in particular to an electrolytic machining device and an electrolytic machining method for island-shaped special-shaped bosses. Background technique [0002] In my country's advanced aviation and aerospace engines, more and more integral structural parts are used. The casing is an important load-bearing part of the aero-engine. It is characterized by large dimensions, thin wall thickness, and various shapes on the inner and outer walls of the casing. Different island-shaped shaped bosses. If mechanical processing is used, there are problems such as large machining removal, long processing cycle, high tool consumption, and difficult to control deformation due to large residual stress. Electrochemical machining can use a forming cathode to realize the forming of complex bosses, cavities and profiles through simple feeding. In the processing of complex structures such as casing, the ...
