Abstract
A zero-point clamping device for centered locking of an object with repeat accuracy, the device comprising: a housing, a receiving opening worked into the housing having a centering axis, at least two clamping slides mounted axially displaceably in a bore provided in the housing, and an actuating element for moving the clamping slides, one axis of rotation of the actuating element running tangentially and at a distance from the receiving opening to enable a reliable, permanent and repeatable fixing of a large number of workpieces and being extremely compact. This is achieved with two spaced-apart threads incorporated in the actuating element, the respective threads of which have identical pitches and are inclined in opposite directions, and a drive pin inserted in each thread in a driving connection with the thread such that the drive pins can be moved along the axis of rotation of the actuating element.
