DEVICE WITH AT LEAST THREE PINS OF CENTERING IN A FIRST COUPLING SYSTEM AND CORRESPONDING SLOTS IN A SECOND COUPLING SYSTEM

摘要

The clamping system, to hold one or more workpieces in defined positions at a machine tool, and the like, has one clutch section (10) and a second clutch section (15) which can be fixed and released. The first clutch section has at least three tapering centering lugs (1-4) which engage in matching grooves (21-24) at the other section. The lugs rest against only one flank (21a,22b,23a,24b) of their grooves, leaving a gap (S1-S4) between them and the other groove flanks (21b,22a,23b,24a). The structure ensures that the clutch facing surfaces are clamped together in the X- and Y-directions and are pressed together on the Z-axis.
