Abstract

A gripping device ( 100 ) for holding, centring and/or clamping a micromechanical or horological component ( 200 ) in a chamber delimited by a collet including at least one movable jaw ( 2 ) and at least one stationary jaw ( 3 ), wherein some of the movable jaws ( 2 ) and/or stationary jaws ( 3 ) include a reference surface ( 20 ) to support a component ( 200 ) bearing frontally thereagainst, and the gripping device ( 100 ) includes both, on the one hand, stationary jaws ( 3 ) including the reference surface ( 20 ) to support the component ( 200 ) bearing thereagainst, and movable jaws ( 2 ) for centring and/or clamping the component ( 200 ), and on the other hand a vacuum generator ( 60 ) for creating the vacuum in the clamping chamber. Also a related method.
