Electro-hydraulic combined system used for electro machining and supporting automatic tool changing

An electro-hydraulic joint supplying system for electrical machining and supporting automatic tool changing, comprising an electro-hydraulic joint supplying device and a clamping device, wherein the electro-hydraulic joint supplying device comprises an insulator, an electro-hydraulic joint supplying base, an electro-hydraulic joint supplying pipe terminal, and an electro-hydraulic joint supplying pipe;

• the insulator is fixedly connected with a spindle shell or a spindle seat of a machine tool spindle;
• a top end of the electro-hydraulic joint supplying base is fixedly connected with the insulator;
• a working fluid pipe connector and a wiring post are arranged on the electro-hydraulic joint supplying base;
• a bottom end of the electro-hydraulic joint supplying base is provided with a terminal connector;
• the working fluid pipe connector and the terminal connector each communicate with a runner in the electro-hydraulic joint supplying base;
• when the terminal connector is in a snap-fit with a top end of the electro-hydraulic joint supplying pipe terminal, the runner in the electro-hydraulic joint supplying base communicates with a runner in the electro-hydraulic joint supplying pipe terminal;
• the runner in the electro-hydraulic joint supplying pipe terminal further communicates with a flushing fluid container in an electrical machining electrode shank through the electro-hydraulic joint supplying pipe;
• the wiring post, the electro-hydraulic joint supplying base, the electro-hydraulic joint supplying pipe terminal, the electro-hydraulic joint supplying pipe, and the electrical machining electrode shank are all conductive and electrically conducted;
• the electrical machining electrode shank and the spindle are insulated from each other;
• the clamping device comprises a first clamping mechanism arranged at a clamping end of a tool changing mechanical arm and a second clamping mechanism arranged on a base clamping unit of a tool magazine;
• the first clamping mechanism or the second clamping mechanism is fixedly connected to a cooperation mechanism on an outer side wall of the flushing fluid container to circumferentially limit the flushing fluid container;
• the working fluid pipe connector, the electro-hydraulic joint supplying base, the terminal connector, the electro-hydraulic joint supplying pipe terminal, the electro-hydraulic joint supplying pipe, and a liquid channel in the electrical machining electrode shank jointly form a working fluid channel;
• the working fluid pipe connector, the electro-hydraulic joint supplying base, the terminal connector, the electro-hydraulic joint supplying pipe terminal, the electro-hydraulic joint supplying pipe, the electrical machining electrode shank, and an electrode jointly form an electric conduction channel;
• and electro-hydraulic combination means that the electro-hydraulic joint supplying device is simultaneously configured as the working fluid channel and the electric conduction channel.
