摘要： In a power-operated chuck (1) with radially adjustable clamping jaws (5) that are attached so as to swivel and be axially adjustable on an articulation lever arranged in a chuck body (2), each of the articulation levers (10) is pivotably mounted on an articulation pin (21) that passes through the articulation levers (10) and the articulation pins (21) are supported in the chuck body (2) so as to prevent rotation and are guided to permit limited axial movement.This embodiment makes it possible not only to carry out precise clampings of workpieces (W) over a long period with a consistently high level of rigidity, but also to avoid wear to a large extent. As a result, workpieces can always be clamped precisely whilst a high level of repeat accuracy is provided.

摘要： A chuck having jaws that are displaceable in radial guideways and can be operated by wedge bars. The wedge bars can be displaced beyond a working space to such an extent that the teeth thereof disengage from the teeth of the pertaining jaw. Each of the wedge bars has disposed therein a pin that projects into the guideways and that has an inclined surface that cooperates with the pertaining jaw; the pin can be displaced against the force of a spring. During exchange of the jaws, the wedge bars can be locked in an end position by the pins.
