ABSTRACT:
A work-holding fixture for clamping a workpiece in position on a work-holding table has a guide shoe (1) and an associated clamping dog (2) which is designed as rocking lever (21) and has extensions (24) which are arranged in the center area and are supported on the guide shoe. A clamping screw (36) is provided at the free end of the clamping dog (2). The recesses (8, 9) are provided in such a way as to be continuous over the length of the guide shoe (1) and are integral parts of a T-slot-shaped cross-sectional configuration of the guide shoe (1). The clamping dog (2) has a curved form in which the free ends of the gripping leg (22) and of the clamping leg (23) are arranged higher than the extensions (24). The extensions have a roughly elliptical cross-section with an orientation of the large axis roughly in the longitudinal direction of the clamping dog (2). The clamping dog has a return spring (30) acting against the clamping direction. For fixing the guide shoe (1) to the work-holding table, only one fixing screw (11) is provided to which one or more apertures (10) in the front region of the guide shoe (1) are allocated.
