Abstract: The clamping and aligning device comprises a frame-like supporting structure supported on or to a base. The supporting structure is held by a clamping device (34). The clamping device is arranged such that two members in a region of a common separating plane (44) of the clamping device are radially perpendicular to a longitudinal axis (46) of the supporting structure from an inside towards an outside and radially arranged in a common plane from the inside towards the outside. The members comprises displaceable clamping elements (50) arranged on clamping surfaces (52). The clamping and aligning device comprises a frame-like supporting structure supported on or to a base. The supporting structure is held by a clamping device (34). The clamping device is arranged such that two members in a region of a common separating plane (44) of the clamping device are radially perpendicular to a longitudinal axis (46) of the supporting structure from an inside towards an outside and radially arranged in a common plane from the inside towards the outside. The members comprises displaceable clamping elements (50) arranged on clamping surfaces (52). The clamping device comprises the two clamping elements jointly acting upon a clamping actuator. The clamping actuator of the clamping device is annular-wedge shaped or one-piece or divided in segments. The clamping elements are arranged by sliding it along or parallel to the longitudinal axis of the supporting structure. The clamping actuator comprises an inclined surface facing away the longitudinal axis of the supporting structure and an inclined surface facing the longitudinal axis of the supporting structure. The inclined surfaces of the clamping elements are engaged such that the clamping elements are arranged on or parallel to the longitudinal axis of the supporting structure by displacement of the clamping actuator. The clamping actuator comprises the inclined surfaces and is inwardly and radially supportable at the supporting structure or at a supporting element of the supporting structure. The clamping actuator is inwardly and radially supportable at the supporting element in form of one-piece or multipart supporting ring and comprises slots secured to the supporting element of the supporting structure and guide elements such as bolts for receiving and guiding the two clamping elements. The clamping device is made from a high-temperature resistant material. A supporting ring or a bath locking ring is receivable in a planned groove or recess such that the members facing a surface of the supporting ring or the bath locking ring are aligned on the clamping surfaces in a plane. The bath locking ring comprises the recess or the groove for retaining a welding material in a welding area. The supporting ring and the bath locking ring are replaceable with one another. The clamping device is: parallel to the displacement of the clamping actuator; and manual, electromotive, mechanical, pneumatic or hydraulic propelled. The clamping elements are designed as a chuck jaw. The clamping surfaces are provided between the two clamping elements and the clamping actuator and/or between the supporting structure or the supporting element and the clamping actuator. A processing device is connected to the clamping actuator, and processes a part of the members by welding, soldering, gluing, cutting, grinding and/or milling. The clamping actuator at the supporting structure is horizontal to the rotational axis and is arranged opposite to the processing device rotatable around the longitudinal axis of the supporting structure.
