Tool adaptor for machine tool spindles

摘要

Several locking pieces (20) are housed in a support (13) and they are locked and unlocked by spring (21) action. The pieces project outside the support application surface turned to the side of the spindle frontal surface (2c). The locking pieces have hook heads (20a) and carry actioning pieces (22,2a) which radially exceed the pincer attack surface when unlocked. Several counter stripping notches (29) are made in the spindle frontal surface and they are adapted to the hooking pieces taking the hook heads in the locked position after pincer opening.
