Abstract
An electrode clamp device for use in electrochemical machines for simultaneously holding a plurality of electrodes made of metallic pipes. The clamp device comprises a clamp block having a plurality of electrode inserting through holes and a plurality of blind tapped holes each of which is perpendicular to the corresponding through hole and has a depth such that the bottom surface of the tapped hole is located in a plane containing the central axis of the through hole to provide an electrode receiving groove in the bottom surface of the tapped hole. Each of the electrodes is individually clamped against the electrode receiving groove with an elastic member by means of a set-screw screwed in the tapped hole.
