Design method for precision electrolytic machining cathode position consistency

Abstract

The invention discloses a design method for precision electrolytic machining cathode position consistency. A positioning pin is additionally arranged on a traditional tool cathode, a cathode standardblock device is additionally arranged on electrolysis equipment, the tool cathode with the positioning pin and the cathode standard block device are subjected to tool setting operation so as to recordstandard coordinate values of the X axis, the Y axis and the Z axis of the electrolysis equipment; when the tool cathode is reinstalled later on, the standard values are used as a judgment reference,the new tool setting values of the X axis, the Y axis and the Z axis are respectively compared with the standard coordinate values, if the difference value of the three values is smaller than 0.05, the position consistency of the tool cathode is considered to be good, and otherwise, the tool cathode needs to be reinstalled until the requirements are met. According to the method, the consistency of the three-dimensional space installation position on the electrolysis equipment can be controlled before the tool cathode is subjected to part machining, so that the inconsistency of installation ofthe tool cathode due to the influence of any factors on the tool cathode and the equipment joint part is avoided.

Description

technical field [0001] The invention belongs to the technical field of precision electrolytic machining, and in particular relates to a method for designing the position consistency of cathodes in precision electrolytic machining. Background technique [0002] The blisk is one of the core components of the fourth-generation and above-generation aero-engines. Because it adopts the structural design of the integrated disc hub and blade, it eliminates the gap between the tenon and tenon in the traditional blade and disc structure. The loss caused by the escape flow in the groove improves the working efficiency of the aeroengine and further increases the propulsion ratio of the engine. At present, the manufacturing process of the blisk is mainly based on milling and electrolytic machining, and with the application of numerical control technology to electrolytic machining Since then, precision electrolytic machining has increasingly become the mainstream processing technology at ...
