Abstract

The invention relates to a complex surface numerical control efficient electrolytic machining tool which comprises a base, a standard platform, an X, Y and Z straight line moving platform, a Y direction numerical control rotating table (a tool B shaft), a Z direction rotating and X direction inclining swinging numerical control rotating table (a tool A shaft and a C shaft), an output end, a stand column, a balance weight, a tool outer cover and the like. According to the tool, feeding of an instrument along a Y and Z space track can be achieved, meanwhile, rotating in the B direction is matched, and blisk blade lattice channel electrolytic machining is completed in a space rotating feeding mode. Through the method, blade body margin difference can be lowered, and irregular hub face machining can be achieved. According to the tool, a workpiece can be obliquely placed according to a corresponding optimized angle, an optimized space angle is formed between the instrument feeding direction and the workpiece, and blisk blade lattice channel electrolytic machining is completed in a space angle feeding mode. According to the method, following blade surface machining accuracy can be improved. According to the tool, efficient electrolytic machining of an aero-engine diffuser, a cartridge receiver and other complex surface parts can be achieved.

Description

technical field [0001] The invention relates to a numerically controlled high-efficiency electrolytic machining machine tool for complex profiles, belonging to the technical field of electrolytic machining. Background technique [0002] Blisk is a new structural part of modern aero-engine, and its application is one of the development trends of advanced engines. Compared with the traditional blisk connected by mortise and tenon, the blisk has the advantages of fewer parts, light weight, less airflow loss, and high safety. At present, some foreign advanced aero-engines have adopted the integral blisk structure. [0003] As an important part of the aero-engine, the blisk has high requirements on machining accuracy and surface quality. Moreover, with the continuous development of the aviation industry, the blisks continue to use high-temperature alloys, titanium alloys and other difficult-to-machine materials, and the blade profiles become more distorted and complex, which br...
