Micro-channel electrolytic machining device

Abstract

The invention discloses a micro-channel electrolytic machining device. The micro-channel electrolytic machining device comprises a spray nozzle used for spraying out an electrolyte. A slit-shaped nozzle is arranged at the spray-out end of the spray nozzle. The spray nozzle is connected with an insulation template used for shielding the electrolyte. A micro-through hole set is formed in the position, corresponding to the slit-shaped nozzle, of the insulation template. The hole diameters of micro holes in the micro-through hole set are matched with widths of to-be-machined micro channels. The design of the spray nozzle is improved, the slit-shaped nozzle is arranged, the fed electrolyte is evenly distributed in a slit range, the insulation template provided with the micro-through hole set isconnected with the spray nozzle, output of the electrolyte to the surface of a workpiece is achieved through the micro through holes in the insulation template, due to the sealing performance of theinsulation template, the electrolyte can be effectively prevented from diffusing to non-machining areas of the workpiece, and the surface quality of the workpiece is prevented from being lowered; andthe widths of the machined micro channels are determined by the micro through holes, thus, the micro channels in different sizes can be machined by adopting insulation templates with different hole diameters, the equipment utilization rate is increased, and the cost is reduced.
