Abstract
To provide a tool mounting device for a turning center that allows a rotating tool to be clamped/fixed using a shared clamp mechanism (), and a turning tool (B) to be clamped/fixed in an engaged/locked state in a turning center. In the turning center configured with the shared clamp mechanism (), a cylinder device () acting as a drawbar drive device () of the clamp mechanism () has a first clamp position (b) and second clamp position (c) in relation to a release position (a); a rotation allowance gap () is maintained between the stopper () and the support unit () in the first clamp position (b) to specifically clamp/fix the rotating tool (A); the reciprocating driver () is driven by an amount equal to the rotation allowance gap () in the second clamp position (c); and when the support unit () and the stopper () are brought into contact and a load is imposed, the stopper () is supported/stopped by the support unit (), and the reciprocating driver () is engaged/locked by the wedge mechanism () in the position of the return blocking state in which the return of the drawbar () is blocked.
