Electrode chucking device and method for electro discharge machine
ActiveCN117620341BGuaranteed to be smooth and flatImprove the safety of useCleaning using toolsElectrical-based auxillary apparatusElectrical connectionElectric spark
The application relates to the technical field of electrode clamping of an electric spark machine, in particular to an electrode clamping device and method of an electric spark machine. The electrode clamping device of the electric spark machine comprises a chuck and a conductive seat which are fixedly connected through a fixing base and coaxially arranged in an upper and lower position. The inside of the fixing base is provided with a scraping plate which can horizontally move laterally at the bottom of the conductive seat and a driving plate which can vertically ascend and descend at the side of the conductive seat. The plate surface of the driving plate is parallel to the lateral moving direction of the scraping plate. When an electrode rod is inserted from the bottom of the chuck and gradually approaches the conductive seat, the driving plate converts the ascending movement of the electrode rod into the horizontal lateral movement of the scraping plate to scrape the bottom end surface of the conductive seat. The scraping plate scrapes the bottom end surface of the conductive seat once every time the electrode rod is installed, so that the electrode rod can be stably electrically connected with the conductive seat every time.
