Embodiment Construction

[0035] Combine below figure 1 , figure 2 and image 3 , illustrate the specific implementation process of the present invention:

[0036] A stepped through hole 21 is designed inside the insulating and sealing fixture 2, and the lower through hole of the stepped through hole 21 is used as the installation positioning hole of the workpiece 1;

[0037] The diameter of the upper through hole of the stepped through hole 21 is larger than the diameter of the lower through hole, which is convenient for the electrolyte solution to flow through;

[0038] The left and right sides of the insulating and sealing fixture 2 are respectively provided with a liquid inlet channel 22 and a liquid outlet channel 23; the electrolyte solution flows in at a high speed from the liquid inlet channel 22 and flows out from the liquid outlet channel 23, filling the first gap between the sheet alloy electrode 3 and the workpiece 1. Two annular gaps form the primary cell.

[0039] The sheet-shaped al...

Abstract

The invention relates to a rotary magnetic fluid assisted grinding casing electrolytic compound processing device and method. The device includes: reference table, insulating and sealing fixture, sheet alloy electrode, excitation insulating sleeve, formed coil winding and sealing end cover, etc. During the processing, a voltage is applied between the workpiece and the sheet alloy electrode, and at the same time, the electrolyte solution flows into the insulating sealing fixture, and flows through the gap between the workpiece and the sheet alloy electrode at a high speed, so that the workpiece is under the action of electrochemical corrosion was dissolved. The excitation insulating sleeve is slidingly and sealedly connected with the sheet-shaped alloy electrode, and the sheet-shaped alloy electrode is pushed downward under the action of the machine tool to shape the workpiece. The tube wall of the excitation insulating sleeve has a built-in coil winding, which generates a magnetic field under the action of an external current, and drives the nanoparticles in the magnetic fluid to continuously grind the surface of the workpiece, which helps to reduce stray corrosion on the electrolytic machining surface of the nesting material and improve the surface quality.

Description

technical field [0001] The invention relates to a rotary magnetic fluid assisted grinding casing electrolytic compound processing device and method, belonging to the technical field of special processing. Background technique [0002] Electrolytic machining mainly relies on the electrochemical dissolution mechanism of the metal anode to remove the workpiece material. This technology has the advantages of no micro-cracks on the machined surface, no stress residue, high productivity, and no tool loss. In view of the above characteristics, electrolytic machining has become an indispensable technology in high-end manufacturing fields such as aviation and medical treatment. [0003] Although electrolytic machining has obvious advantages, stray corrosion is inevitable in the machining process, which affects the machining accuracy and restricts the application of this technology. Aiming at the problem of stray corrosion, domestic researchers have conducted a lot of research and ac...
