Abstract

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.

Description

technical field

[0001] The invention relates to a clamping mechanism comprising a first link, provided with at least 3 central pins, having an at least partial taper; and a second link, releasably connected to said first link. The second connecting piece is provided with a plurality of grooves, the number of which corresponds to the number of center pins provided on the first connecting piece, when the second connecting piece is connected to the first connecting piece, the number of center pins provided on the first connecting piece The center pin engages the slot.

[0002] Both the first link and the second link have Z-direction reference stop surfaces that can cooperate with each other to determine the Z-direction position of the second link relative to the first link when the second link is connected to the first link . Background technique

[0003] This coupling mechanism is preferably used for clamping joints with one or more workpieces located at precise positions in...
