Abstract (en)
[origin: EP0816516A1] The tap hole drilling machine incorporates a column (18), an arm (20) which is pivotable about an axis (22), and a drill carriage (26) which is attached to the arm and is pivotable relative to the arm about an axis (28). It further includes link bars (34', 34") connected by means of hinges (36', 36") and (40', 40") respectively to the column (18) and to the drill carriage (26), to create a transmission unit in which a pivot motion of the arm (20) about the axis (22) produces a pivot motion of the drill carriage about the axis (28). The machine has a switching mechanism (44', 44") which transfers the link bars (34', 34") from a first position into a second position in the transmission unit.
