A chuck for clamping workpieces or tools in a clamping space with a clamping force (F). The chuck includes at least two chuck jaws movable in translation along one clamping plane (E) in the direction of one center Z of the clamping space and a gear train located at least largely within the chuck for transfer of a driving torque of a drive motor, which can be coupled to the gear train by coupling means of the gear train, to the chuck jaws for movement of the chuck jaws. The coupling means able to be coupled to a corresponding coupling connection of the drive motor. The movement from the maximum size of the clamping space to the minimum size of the clamping space is executed via the gear train from the drive motor.

An insulating housing of an electrical terminal device includes a latching pin arranged on a front side of the housing and that protrudes therefrom in a direction perpendicular to a plane of the front side of the housing, the latching pin engaging in a latching hole arranged on a rear side of the housing in a direction perpendicular to a plane of the rear side of the housing, and a latching hook that protrudes from the front side of the housing and that engages in and latches behind a catch arranged on the rear side of the housing. The latching pin and the latching hole are in the shape of a truncated cone. A plurality of the insulating housings is capable of being plugged on top of one another to form an electrical terminal block.

A high-precision two-part flat chuck device includes: a base, a cylinder, a sliding plate, a first clamping plate and a second clamping pate. A piston rod of the cylinder is connected with the sliding plate. Precision sliding rails are arranged at two sides of the base, and two sides of the sliding plate are respectively matched with the precision sliding rails in a sliding manner. An accommodating groove is arranged in a middle part of the sliding plate. The first and second clamping plates are symmetrically distributed in the accommodating groove along a center of the sliding plate, and a spring is arranged between the first and second clamping plates. Side surfaces of the first and second clamping plates are inclined planes, and chucks matched with each other are arranged at end parts of the first and seconding clamp plates.

A workpiece clamping device for a machine tool is provided, which has a base, first and second clamping jaws between which a workpiece is clampable, a drive, and an actuating element which is displaceable relative to the base and which is coupled to the first clamping jaw. A movement of the actuating element is brought about by the drive and the actuating element brings about a displacement of the first clamping jaw. A transmitter is arranged on the actuating element and is displaceable together with the actuating element and is displaceable relative to the actuating element. A first stop and a spaced-apart second stop are provided, between which stops the transmitter is displaceable together with the actuating element. When the transmitter abuts against the first or second stop, the transmitter is displaceable relative to the actuating element. A sensor is provided for detecting one or more positions of the transmitter.
