Device for connecting two tool sections

摘要

A device for connecting two tool parts having a common axis. The device includes a fitting pin projecting axially from the first tool part and a connecting sleeve from the second tool part and having a mating bore for receiving the fitting pin. A tightening mechanism equipped with a tightening bolt movable in a crossbore of the fitting pin assures a sufficient planar surface to planar surface tightening between the two tool parts. Aside from the tightening in direction of the tightening bolt, a clamping of the fitting pin into the mating bore of the connecting sleeve is achieved through suitable measures, the clamping extending transversely with respect to the tightening-bolt direction and resulting in an automatic centering of the tool parts with respect to their common axis and in a reinforcement of the connection transversely with respect to the tightening-bolt axis.
