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. More particularly, four clamping bodies can be present, each with a longitudinal axis, wherein four intersection points are formed, in each of which two of the available longitudinal axes intersect.
