Electrolytic machining clamp and electrolytic machining method for fuel nozzle orifice

The invention discloses an electrolytic machining clamp and an electrolytic machining method for a fuel nozzle orifice, according to the clamp, a cathode is mounted on a cathode positioning and aligning assembly and is mounted on a machine tool spindle through a spindle connecting block, so that the up-and-down movement adjustment of the cathode can be realized, the cathode is very convenient to mount and dismount, and the machining efficiency is greatly improved. And in addition, the perpendicularity of the cathode can be conveniently aligned and adjusted, and the machining perpendicularity of the spraying hole in the fuel nozzle is guaranteed. And moreover, the electrolyte circulating channel with an open flow field design is adopted, so that the structural design of the electrolyte circulating channel can be more flexible and changeable. By the adoption of the electrolytic machining clamp, the electrolytic machining technology can be applied to spraying hole machining of the fuel nozzle, material corrosion
