<p>A workpiece carrier comprises a base with an upper part rotatable about a vertical axis and a lower part connected to the upper part at a distance by bolts. Workpiece holders each comprise a sleeve of elastically deformable material like rubber surrounding a duct where the shaft of a workpiece can be inserted, the sleeve being accommodated in a recess on the base. The vertical position of the sleeve which extends through holes in the upper part and lower part of the base, respectively, is fixed by a stop formed between a recessed rim surrounding the hole in the lower part and a downward-facing projecting rim of the sleeve. The shaft can be fixed by swivelling a lever about one of the bolts into an active position where a compressing surface of the same compresses the sleeve such that the shaft is jammed and released by swivelling the lever back into an inactive position where the compressing surface is not in contact with the sleeve.</p> |
