Abstract

PURPOSE:To simplify the construction of a finger locking unit for a tool exchange device by maintaining a locking shaft in an unlocked state by measn of a tool ascertaining rod while a tool is not clamped by fingers, whereby a mechanism for releasing locked fingers before a tool has been clamped thereby. CONSTITUTION:A front shaft head 10 is lowered and a tool 13 fitted into a main shaft 11 is separated from fingers 17, 18 as the fingers 17, 18 are outwardly urged by the tool 13 against the resilient forces of springs 21, 22. A tool ascertaining rod 29 is then moved forwardly by the resilient force of a spring 33 to be engaged with a tapered engagement portion of a locking shaft 26 which is adapted to lock the fingers 17, 18. As a result, the locking shaft 26 is held unlocked. Accordingly, an operation for releasing locked fingers 17, 18 with a cam before a tool has been clamped thereby becomes unnecessary.
