Abstract
In order to obviate the need for exchanging tools, e.g. tongs, together with their drive mechanisms, the quick-action coupling device (4) is provided between a toolholder (3) and the tool (5) and consists essentially of two coupling half shells (9, 10), one of which is fixedly mounted on a rotary spindle (7) supported in the toolholder (3) and drivable if required, and the other of which is fixedly arranged at the toolhead (11); these half shells are radially coupled and then locked. The locking device (21) is designed so that, in the unlocked condition, the rotary drive mechanism (6) of the rotary spindle (7) is blocked. The quick-action coupling device (4) also permits a linear drive action (8, 19) for opening and closing tongs (5a, 5b) or the like, and is capable of transmitting high bending moments and/or torques with simultaneously high transverse and longitudinal forces.
