Abstract: The invention relates to a clamping device and is designed for releasably clamping a supporting body on which a workpiece can be arranged. The clamping device has a main body with receiving bores each for receiving a clamping bolt of the supporting body. Each clamping body can be moved linearly along the longitudinal axis thereof between a clamping position and a release position. The movement from the release position into the clamping position and/or conversely from the clamping position into the release position can be effected by means of an actuation device. Each clamping body has a clamping end which protrudes into an associated receiving bore in the clamping position. The longitudinal axes of the clamping bodies form a plurality of intersection points in a common projection plane parallel to which the longitudinal axes extend. In a preferred embodiment, at least three or four intersection points are formed.

Abstract: For an accurate clamping of a workpiece chuck (2), a clamping device (1) has a reference-plane plate (4) and a clamping plate (3) which are brought into a face-to-face contact with one another. In another reference-plane plate (4) clamping openings (8, 9, 10, 11) are formed with which clamping and positioning pins (21, 22, 23, 24) are associated. The latter are held on the clamping plate (3). The clamping and positioning pins (21, 22, 23, 24) utilize a portion of the wall (12, 13, 14, 15) of the clamping openings (8, 9, 19, 11) as reference surfaces, when they are resiliently pressed thereagainst. For this purpose a tightening device (40) is provided which not only clamps the clamping and positioning pins (21, 22, 23, 24) axially, but also presses them against the bore wall in a different radial direction.
