Fabrication of Surface Functional Microstructure Devices by Mask-Assisted High-speed Dissolvable Abrasive Electrohydraulic Jet

Abstract

The invention discloses a mask-assisted high-speed soluble abrasive particle electro-hydraulic jet manufacturing surface function microstructure device, which includes a motor, a workpiece placement seat, a processing tank, a cylinder, a circulation pump, a nozzle, an angle plate and a cathode plate, and is rotated by a motor Then it drives the screw rod to rotate, so that the first slider moves on the screw rod, which further drives the nozzle to move directly above the workpiece, and uses the cylinder to drive the piston rod to expand and contract, thereby realizing the adjustment of the height of the second horizontal plate, thereby further realizing The nozzle height can be adjusted to meet the different height requirements of the nozzle in different situations, and the practicability of the equipment is improved. The passivation electrolyte in the processing tank enters the nozzle through the liquid guide hose and further passes through the outlet by using the circulation pump. The material port is sprayed out, and the abrasive supply system is further used to make the abrasive enter the nozzle through the material guide tube and follow the passivation electrolyte to be sprayed out through the material outlet, so as to realize the purpose of processing the surface of the workpiece.

Problems solved by technology

The electro-hydraulic jet method is a mature microstructure processing technology. However, the fineness and precision of the processing of this method depend on the aperture and arrangement of the nozzles. Because the nozzle manufacturing process is complex and expensive, and it is easy to deform during processing, making This approach is severely limited in the fabrication of surface functional microstructures
