Triaxial driving device for an electrodischarge machine tool

摘要

A triaxial driving device (1) for electrodischarge machine tools and has a connecting mount (10), a first axial rotator (30), a base (20), a supporting arm (40), a second axial rotator (50), a third axial rotator (60) and an electrode holder (70). The first axial rotator (30) is mounted in the connecting mount (10) and has a rotating head (31). The base (20) is connected securely to the rotating head (31) and has a space (23). The supporting arm (40) is mounted in the space (23) and has a connecting frame (41). The second axial rotator (50) is securely connected to the base (20) and the supporting arm (40) and has a rotating head (51). The third axial rotator (60) is connected to the supporting arm (40) and has a rotating head (61). The electrode holder (70) is connected to the third axial rotator (60).
