Embodiment Construction

[0022] Figure 1a shows a top view of a first substantially cylindrical connecting element 10. Figure 1 b shows a side view of the first substantially cylindrical connecting element 10 . Typically, this first attachment 10 is connected to the machine tool and serves as a clamping member for a second attachment 15 as shown in Figures 2a and 2b, which can receive a workpiece, tool or similar.

[0023] On the top of the first connecting piece 10, four center pins 1, 2, 3, 4 protrude. These center pins are offset from each other by 90° with respect to the center line Z. Each central pin 1, 2, 3, 4 comprises two tapered sides 1a, 1b, 2a, 2b, 3a, 3b, 4a, 4b.

[0024] Between the two central pins 1, 2; 2, 3; 3, 4; 4, 1 there is an intermediate surface 6 which serves as a reference in the Z direction. In the middle of the surface 6, an outlet 7 is provided to allow the air to escape. For fixing, the first connecting piece 10 is provided with a plurality of fixing holes 12 .

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...
