の金属工作機械用チヤツク。[Scope of Claim for Utility Model Registration] 1. A chuck for a metal machine tool that opens and closes a grasping claw by advancing and retracting a drawbar, which is attached to the spindle head of a metal machine tool, has a wedge shaft hole in the axial direction, and has a wedge shaft hole and a wedge shaft hole. The chuck body has intersecting link shaft guide holes and is connected to a drawbar through which the main shaft of a metal machine tool is inserted.The chuck body is fitted into a wedge shaft hole in the chuck body so as to be movable in the axial direction, and is installed obliquely with respect to the axial direction. A wedge shaft having a wedge-shaped portion, a wedge-shaped hole that slides into the wedge-shaped portion of the wedge shaft, and a link shaft that fits into the link shaft guide hole of the chuck body, and a grasping pawl disposed on perpendicular surfaces, with the grasping surface facing the side of the chuck body and supported so as to be movable forward and backward toward the side of the chuck body; and a transmission member that transmits the movement of the link shaft to the grasping pawl; A chuck for a metal working tool, characterized in that it is provided with a receiver fixed to the chuck body, facing the gripping jaw with a workpiece interposed therebetween. 2. A chuck for a metal machine tool that opens and closes a grasping claw by advancing and retracting a drawbar, which is attached to the main spindle head of the metal machine tool, has a wedge shaft hole in the axial direction, and has a link shaft guide hole that intersects with the wedge shaft hole. a wedge shaft which is connected to a drawbar through which the main shaft of a metal machine tool is inserted, is fitted into a wedge shaft hole of the chuck body so as to be movable in the axial direction, and has a wedge-shaped portion obliquely disposed with respect to the axial direction; , provided with a wedge-shaped hole that slides into the wedge-shaped portion of the wedge shaft, and arranged on a surface perpendicular to the axial direction of the chuck including the link shaft and the link shaft that fits into the link shaft guide hole of the chuck body, A pair of links, one end of which is pivotally connected to the link shaft, one end of which is pivotally connected to the other end of the link, and the other end is provided with a grasping claw with a grasping surface facing the side of the chuck body, and the intermediate portion is attached to the chuck body. A chuck for a metal working tool, comprising a link device consisting of a pair of levers pivotally connected to the chuck, and a catch fixed to the chuck body, facing the gripping claw with a workpiece interposed therebetween. 3. Provide a gap between the link shaft and the link shaft guide hole of the chuck body so that at least the tip of the link shaft can move in a direction substantially perpendicular to the axial direction of the link shaft on a plane including the link shaft and perpendicular to the chuck shaft direction. 3. A chuck for a metal working tool according to claim 1, further comprising: a chuck for a metal working tool. 4 The drawbar and the wedge shaft are eccentric, and the chuck body is fixed to the spindle head of the metal machine tool and is attached so that it can rotate relative to the spindle center in the unlocked state. A driving-side shaft coupling portion is provided, and a passive-side shaft coupling portion is provided at the rear end of the wedge shaft so as to be able to be engaged with and detached from the driving-side shaft coupling portion provided at the tip end side of the drawbar by rotation. 4. The metal working tool according to claim 1, wherein the shaft coupling portions on the drive side and the passive side are engaged and disengaged by relative rotation with respect to the spindle head together with the wedge shaft carried by the chuck body.
