The efficient and precise electrolytic machining device comprises a three-way electromagnetic valve, a sealing liquid collector, an elastic clamping body, a conical surface locking sleeve, a supporting base, a conductive woven belt, an elastic clamping body cooling pipe, a supporting base cooling pipe,a forming cathode, a cathode pull rod, a double-clack type support, a machine tool control cabinet and a four-way electromagnetic valve, wherein two sets of clamps are connected through the conductivewoven belt, and joule heat is evenly distributed on a whole workpiece; cooling water channels are installed on the clamps and an inner sleeve; and after electrolytic machining is completed, the electromagnetic valves are precisely controlled through a machine tool control system. The manner that the conical surface of a locking assembly is matched with the locked workpiece is adopted, on the premise that clamping force is guaranteed, the conductive area is increased, uniform conduction of the workpiece and a clamping device is achieved, heat generated in the machining process is released in time, and temperature distribution at the contact face is uniform.

Description

technical field [0001] The invention relates to the field of electrolytic processing equipment manufacturing, in particular to a high-efficiency and precise electrolytic processing equipment and a processing method thereof for a titanium alloy complex inner helix. Background technique [0002] Titanium alloys have the advantages of high strength, light weight, and good corrosion resistance, and are widely used in aerospace, military equipment and other fields. However, titanium alloy materials have low thermal conductivity and poor heat dissipation. Using traditional mechanical broaching to process complex parts such as titanium alloy special-shaped inner helixes has technical bottlenecks such as low processing efficiency, easy sticking to the knife, severe tool wear, and poor processing quality. . Electrolytic machining is a kind of non-contact machining, which has the advantages of good surface quality, high production efficiency, no tool loss, no cutting stress, etc. It ...
