Device for positioning an machining unit relatively to a workpiece, in particular for transfer lines.

摘要

The device enabling an operational unit to be positioned relatively to a workpiece, particularly useful with transfer lines, comprises a guide (4) which extends in a vertical plane with a semicircle pattern and a holder (7) for the operational unit adjustably mounted on said guide and having plural degrees of freedom. The holder is provided with slides (8, 22, 58) cooperating with fluid-operated jacks (37, 38, 48, 49) which enable the operational unit to be displaced to effect its working travel movements.
