The invention relates to a positioning device (2) for detachable and repeatable positioning in X-, Y- and Z-directions of a first object (4) in relation to a second object (6), the positioning device (2) comprising a first XY-reference means (8) and a second corresponding XY-reference means (10), wherein the first XY-reference means (8) is a disc spring with a in Z-direction tapered conical inner surface (12) and the second XY-reference means (10) is a element with an in Z-direction tapered conical outer surface (14), where further the first XY-reference means (8) is arranged to be fixed to the first object (4) and the second XY-reference means (10) is arranged to be fixed to the second object (6), where in operating state of the device the first object (4) is positioned in the Z-direction in relation to the second object (6) by that the second object (6) is arranged to support the first object (4) in the Z-direction, and where at the same time the conical outer surface (14) of the second XY- reference means (10) is arranged to abut against the conical inner surface (12) of the first XY- reference means (8) thus in turn positioning the first object (4) in relation to the second object (6) in X- and Y-direction. |
