rapid and automatic rotary locking device of a portautensile in a body dirotazione solidarity, for example, a machine tool or a milling machine.

摘要

The device is suitable and intended in particular for rotary tools operating at high and maximum speeds, the rotary locking between the toolholder (2) and the rotatable body (1) of the machine being obtained by means of pistons (7, 8) which are arranged radially opposite one another in the toolholder and which in turn press with their bevelled heads by means of the centrifugal force against an annular surface in the interior of the body (1).
