Abstract

The invention provides a pulse dynamic electrolytic machining device and method for quickly leveling the surface of a rotating body, and relates to the technical field of electrolytic machining. The workpiece rotates around the center point of the anode workpiece at a set angular velocity, while the cathode tool moves along the line connecting the cathode tool and the anode workpiece at a set feed rate; the control system is based on the outer circle profile data of the anode workpiece collected by the displacement sensor Determine the processing voltage value output by the power supply when each contour point of the anode workpiece rotates to the processing area to automatically change the connection voltage between the cathode tool and the anode workpiece; the present invention shortens the transition time of the rotating pulse dynamic electrolytic machining by adopting a variable voltage method, so that The processing quickly enters the stable processing period, which improves the processing efficiency, and at the same time significantly improves the surface quality and forming accuracy of the boss surface of the casing parts during the spin-printing electrolytic machining process.

Description

technical field [0001] The invention relates to the technical field of electrolytic machining, in particular to a pulse dynamic electrolytic machining device and method for rapidly leveling the surface of a rotating body. Background technique [0002] The electrolytic machining method is a special processing method based on the principle of electrochemical anodic dissolution to remove materials. Compared with the traditional mechanical processing method, the electrolytic machining method has wide material applicability, high processing efficiency, and no cutting stress in the processing process, which is suitable for processing thin-walled parts, no tool loss, and good surface quality. Therefore, the electrolytic machining method is suitable for thin-walled parts, space-complex curved surfaces, and difficult-to-cut superalloy materials. [0003] The casing parts are the key components of the aero-engine, distributed in multiple parts of the aero-engine, supporting the rotor...
