Abstract

Disclosed is a device for aligning a workpiece in a mass-centering device, in which in an initial position an upper flange (1) and a lower flange (2) are arranged concentrically around an axis (3) of a balancing spindle of the mass-centering device, with the upper flange (1) comprising an interface (4) for clamping means to clamp the workpiece, and the lower flange (2) an interface (5) for fastening means to fasten the device to the balancing spindle. At least two spring elements (22, 23) reside between the upper and the lower flange (1, 2), such that in the initial position the upper flange (1) takes support axially and radially exclusively on the two spring elements (22, 23). In the initial position, the upper flange (1) is movable relative to the lower flange (2) into an eccentric position by a force acting in opposition to the spring elements (22, 23). A displacement device comprising a compression spring (9) and a piston (13) is arranged between the upper and the lower flange (1, 2) such that in a clamping position the piston (13) is movable, by the force of the compression spring (9), into engagement with a supporting element (20) of a fastening element (21) of the upper flange (1), so that the piston (13) enables the upper flange (1) to be clamped against the lower flange (2) and to be arrested in the eccentric position.
