ABSTRACT:
The invention pertains to a clamping chuck consisting of a fork-like clamp jaw holder (1) to which an adjusting element (2) moving back and forth in the longitudinal extension of the clamp jaw holder (1) is provided for the relative movement of the clamp jaw supports (3, 4) with respect to each other in the clamped and open setting. According to the invention, in each leg (5) of the clamp jaw holder (1) one bearing hole (6) and four additional holes (7, 7') are mutually aligned laterally, with their centers (Z) positioned on the corners (E) of the square (Q). The two bearing holes (6) are arranged centrally on the respective connecting line (L) of the two holes (7') on the clamp jaw side and the two clamp jaw supports (3, 4) provided on the clamp jaw holder (1) have a drilled hole (6') aligned with the bearing hole (6). In this case the moving or pivoting clamp jaw support (3) has features (8) for a frictional and/or form-fit actuated connection with the adjusting element (2). In this case the clamp jaw support can be oriented in different directions on the clamp jaw holder (1), without having to change it, and also differently configured clamp jaw supports can be provided on the clamp jaw holder (1).
