What is claimed is: 1. A device for joining assembled hollow shafts comprising a tube defining an axis and attachable parts slid on to the tube, the device comprising: a single positioning and fixing unit (40) for the attachable parts; and a single holding and positioning device (20) for the tube,
What is claimed is: 1. A device for joining assembled hollow shafts comprising a tube defining an axis and attachable parts slid on to the tube, the device comprising: a single positioning and fixing unit (40) for the attachable parts; and a single holding and positioning device (20) for the tube, wherein the tube, inside the attachable parts, is radially plastically expanded in individual portions by applying internal pressure in such a way that the attachable parts are secured to the tube by a permanent press fit, and wherein the positioning and fixing unit (40) is fixed in space, and the holding and positioning device (20), with reference to the tube axis, is axially and rotatingly drivable relative to said positioning and fixing device (40). 2. A device according to claim 1, wherein an axis of the holding and positioning device (20) for the tube and a holding axis of the positioning and fixing unit (40) are aligned vertically. 3. A device according to claim 2 comprising a probe member (64) for expanding individual portions of the tube, wherein the probe member (64) comprises one single operating portion for expanding one individual portion of the tube (18). 4. A device according to claim 3, wherein the probe member (64)is adjustable between two axial positions, with the operating portion being positioned in a lower position below the positioning and fixing unit (40) and in an upper position inside the positioning and fixing unit (40). 5. A device according to claim 1 comprising a probe member (64) for expanding individual portions of the tube, wherein the probe member (64) comprises one single operating portion for expanding one individual portion of the tube (18). 6. A device according to claim 5, wherein the probe member (64) is adjustable between two axial positions, with the operating portion being positioned in a lower position below the positioning and fixing unit (40) and in an upper position inside the positioning and fixing unit (40). 7. A device according to claim 5, wherein the holding and positioning device (20) comprises a first holding device (22 ) for an exchangeable chuck (17, 23) for a tube. 8. A device according to claim 7 comprising a workpiece transporting unit (10) including a second holding device (16 ) for an exchangeable chuck (17, 23) for a tube. 9. A system according to claim 8, wherein the workpiece transporting unit (10) comprises a die (14) for a complete set of attachable parts for a tube. 10. A device according to claim 1, wherein the holding and positioning device (20) comprises a first holding device (22 ) for an exchangeable chuck (17, 23) for a tube. 11. A device according to claim 10 comprising a tool changing device (25) arranged at the holding and positioning device ( 20) for handling exchangeable chucks (17, 23). 12. A device according to claim 10 comprising a workpiece transporting unit (10) including a second holding device (16 ) for an exchangeable chuck (17, 23) for a tube. 13. A system according to claim 12 wherein the workpiece transporting unit (10) comprises a die (14) for a complete set of attachable parts for a tube. 14. A device according to claim 12 comprising a tool changing device (25) arranged at the holding and positioning device ( 20) for handling exchangeable chucks (17, 23). 15. A device according to claim 1 including a transport track (13) and a clamping mechanism for a workpiece transporting unit (10). 16. A device according to claim 1 comprising a horizontal transporting unit (30) for receiving and transferring individual attachable parts from a stand-by position into the positioning and fixing unit (40). 17. A system comprising a plurality of joining stations ( 80) each for joining assembled hollow shafts including a tube and an attachable part slid onto the tube wherein the tube, inside the attachable parts, is radially plastically expanded in individual portions by applying internal pressure in such a way that the attachable parts are secured to the tube by a permanent press fit, each joining station ( 80) comprising a single positioning and fixing unit (40) for the attachable parts and a single holding and positioning device ( 20) for the tube, the individual stations (80) being connected to one another linearly or in a loop via a transport path (81), and wherein the system comprises workpiece transporting units (10) transportable from station to station which each comprise a first holding device (16) for an exchangeable chuck for a tube, and wherein the holding and positioning device (20) of each joining station ( 60) includes a second holding device (22) for an exchangeable chuck for a tube. 18. A system according to claim 17 comprising at least one rotary station (82) for rotating a workpiece transporting unit ( 10) along the transport path (81). 19. A system according to claim 17 comprising at least one equipping station (83) for equipping each workpiece transport unit (10) with a complete set of attachable parts.
