Patent attributes
There is provided an innovative tool mounting device for a turning center in which special manipulation is not required even with a simple configuration, and whereby when a cutting tool is clamped/fixed, the bearing unit is deformed by the retraction force of the drawbar because the cutting tool is supported by the ram, the tapered shank is automatically pressed to the mounting engagement unit in a state in which the cutting tool is supported by the ram, an automatic mechanical lock in a state of dual-surface restraint can be implemented, and the turning tool can be securely clamped/fixed. The tool mounting device for a turning center is configured so that a positioning strike receiving portion (29) is provided to a ram (3) with which the positioning outer surface (28) of a turning tool (1B) makes contact when at least the turning tool (1B) is clamped/fixed, the positioning outer surface (28) strikes the positioning strike receiving portion (29) when a drawbar (7) is retracted, a bearing unit (2) is deformed by the retraction force applied to the drawbar (7) of the clamp mechanism (8) because the retracted position of the drawbar (7) is maintained in the struck state, and the mounting engagement unit 6 exerts elastic pressure/contact on the tapered shank (5).
