The invention relates to an automatic centring, sealing and clamping device for machining, in particular in the case of elongated workpieces, such as, for example, tubes. In order to provide an automatic centring, sealing and clamping device for machining elongated workpieces, such as, for example, tubes, with which the workpiece is centred, sealed and clamped via the axial applied pressure and the requisite torque is transmitted while the workpiece is sealed off, a design is proposed which is characterised by two opposite, annular basic bodies (1) with cylindrical extensions (2) facing one another for accommodating an axially movable clamping-lever ring (3) which is provided with sealing elements and on which at least two pivotable clamping levers (4) of angular design with interchangeable clamping shoes (5) located on one lever arm are arranged, in which arrangement the clamping levers (4), with a spherical bearing surface (6) provided on the other lever arm, bear under spring pressure against the basic body (1) and are guided laterally in guide slots (7), and by an interchangeable, annular adaptor (8) which bears against the ring (3) and has a sealing element (13) inserted at the end face. <IMAGE>
