ABSTRACT:
There is disclosed herein an improved tool holder/adapter for use in a mechanical and automatic machine tool. The machine tool includes: (1) a drive spindle; and (2) a rotary turret for releasably storing a plurality of tool holder/adapters. Each holder/adapter is secured to the turret by a set of radially movable locking pins which are cammed to a radially outward position. There is also provided a set of axially movable travel limit stop pins for cooperation in maintaining the locking pins in a radially outward position. The travel limit stop pins cooperate with the spindle for releasing the locking pins and permitting them to move radially inwardly so as to release the tool holder/adapter from the turret. The stop pin construction and location combine to provide both positive and blocking engagement between the lock pin and stop pin so as to prevent unintentional inward movement of the lock pin and possible unintentional holder/adapter-turret disengagement.
