摘要： The invention relates to a chuck for flexible manufacturing, said chuck comprising a chuck body, a central draw head guided axially in a central hole of the chuck body and connected to inner jaws radially guided in the chuck body through a straight-wedge mechanism, and outer jaws also radially guided in the chuck body and adapted to be equipped with chuck jaws for chucking a work-piece and to be engaged with coupling heads through rack teeth. The coupling heads are built in the inner jaws and guided axially therein, wherein said coupling heads comprise a double locking coupling device. The first locking stage of said coupling device includes wedge-shaped control members fixed to a control ring, whereas the second locking stage includes an additional locking member directly connected to the control ring. The chuck body is in the form of a one-piece unit, wherein the control ring is encased by the chuck body and the rear centering disc so that the control ring can be rotated there-between. and the locking member of the second locking stage is in the form of a cylindrical stud-shaped lock guided in an axial hole of the control ring, said lock being connected, in its locked state, through its front surface, to an axially guided push-rod, wherein said push-rod is arranged in an entirely closed hole of the chuck body.
