Abstract:
A turret tool rest (10) includes a tool slide (20), a tool rest body (22) movably provided on the tool slide, a turret (26) rotatably supported on the tool rest body, the turret permitting desired tools (24) to be individually mounted at predetermined angularly-indexed positions, a servomotor (30) for rotationally driving the turret, a clutch unit (32) for operatively connecting the turret with the servomotor in a releasable manner, an engaging unit (36) for engaging the turret with the tool rest body in a disengageable manner, and a power transmission device (38) for transmitting an output of the electric motor to the engaging unit so as to operate the engaging unit. A drive mechanism (34) for operating the clutch unit includes an interlocking device (72) operative in association with the movement of the tool rest body on the tool slide. When the engaging unit is in a disengaged state, the clutch unit is put in a connecting state by the operation of the drive mechanism and the turret is driven by the servomotor to perform the indexing rotation. When the clutch unit is in a releasing state, the engaging unit is put in an engaged state by the operation of the servomotor and the turret is secured at an indexed position on the tool rest body.
