Clamping device for joining tool holding element to turret head of machining device, comprising specifically shaped shaft surface

摘要

The device (1) is divided into a cylindrical front area (9) to be inserted into the tool, a collar (2) serving as a stop, and a shaft (3) of a smaller diameter than the front area (9). The shaft (3) is provided with a longitudinal groove (4) for being precisely guided axially and a recess at the upper end of a second groove parallel to the collar (2) in order to facilitate a tight joining of the collar surface to the contact surface at the turret head.
