Patent ID: 8866035

Claim:
A triaxial driving device for an electrodischarge machine tool having a three-liners-axes mechanism with three axes (X-, Y- and Z-axes) and an electrode tool, and the triaxial driving device comprising a connecting mount being adapted to connect securely to the three-liners-axes mechanism of the electrodischarge machine tool; a first axial rotator mounted in the connecting mount and having a top mounted in the connecting mount; a bottom extending out of the connecting mount; and a rotating head mounted on the bottom of the first axial rotator; a base connected securely to the first axial rotator to enable base to rotate relative to the connecting mount around the three-liners-axes mechanism along the Z-axis of the three-liners-axes mechanism and having a space; a supporting arm rotatably mounted in the space of the base and having an outer end rotatably mounted in the base; an inner end extending in the space of the base; and a connecting frame connected to the inner end of the supporting arm and having a front side; a second axial rotator securely connected to the base and the supporting arm and having an inner side securely mounted in the base; an outer side extending out of the base; and a rotating head mounted on the inner side of the second axial rotator and securely connected to connecting frame to enable the connecting frame to rotate relative to the base around the three-liners-axes mechanism along the X-axis of the three-liners-axes mechanism; a third axial rotator securely connected to the supporting arm and having an inner side securely mounted in the front side of the connecting frame of the supporting frame; an outer side extending out of the connecting frame via the front side of the connecting frame; and a rotating head mounted on the outer side of the third axial rotator; and an electrode holder securely connected to the third axial rotator, being adapted to connect to the electrode tool of the electrodischarge machine tool and having a mounting end securely mounted on the rotating head of the third axial rotator to enable the electrode holder to rotate relative to the connecting frame of the supporting arm around the three-liners-axes mechanism along the Y-axis of three-liners-axes mechanism.
