Drill chuck

Abstract

A drill chuck having a chuck body connectable to a drilling spindle, in which are arranged clamping jaws in guide seats extending at an angle to the chuck axis, which jaws are movable for opening and closing via a threaded ring that is arranged to be rotatable and axially immovable relative to the chuck body. A locking device includes a coaxial ring of locking recesses as well as at least one locking element that is engaged in the locking recesses under the force of a locking spring. An adjusting ring rotatable to a limited extent between stops, the rotation of which adjusts the locking element. A detent device creating two detent positions in the circumferential direction. The threaded ring is designed as an undivided threaded ring with an opening width that is larger than the diameter of the axially forward section of the chuck body. Attached to the axially forward section of the chuck body in a rotationally fixed and axially immovable manner is a locking sleeve that carries the ring of locking recesses and serves to axially secure the threaded ring.
