ABSTRACT:
When used as holder for tools for partial machining tasks or as clamping means for exchangeable tools, the clamping block for clamping workpieces or tools make it possible to carry out a rapid and precisely reproducible exchange of the object (7) to be clamped. The clamping block having a block base (1) and a clamping jaw (5) which can be displaced relative thereto comprises a fixed clamping jaw (3) and means (4, 4.2) for the at least approximately parallel guidance of the moveable clamping jaw (5) relative to the block base. The latter has an essentially L-shaped form with two legs (1.1, 1.2) of approximately equal length. One of these carries the fixed clamping jaw (3) and a nose-shaped supporting portion (4) having a wedge-shaped control surface (4.2) for the moveable clamping jaw (5) while the other has a table-shaped portion (8) on which means for lateral and transverse guidance of the moveable clamping jaw (5) are supported.
