ABSTRACT:
A drilling device includes a frame with a stationary and a movable upright and a transverse beam which connects said uprights with each other along which a drilling unit moves transversely to the advance direction of the workpiece and is set to provide boreholes in accordance to the center of a standard workpiece of nominal height. The workpiece is transported by a roller table and clamped by the movable upright to define a clamping path. Connected to the movable upright is a lever assembly which transmits the horizontal movement of this upright to a vertical bar. The displacement of the vertical bar rotates a horizontal rod which is linked via a crank arm/lever assembly to a transmission bar moved in horizontal direction upon rotation of the rod. The transmission bar is connected to a correction unit which in response to the determination of the clamping path acts on the drilling unit to adjust the latter in dependence on the actual height of the workpiece.
