| 摘要 |
The invention relates to a clamping device for rod-shaped profiled elements with a substantially circular cross section and with a central axis (R) of the profiled element which axis runs along a longitudinal direction (L) of the rod-shaped profiled element. The device has at least two centering clamps distanced from each other along a theoretical central axis (S), and has at least two opposing clamping cheeks that can be centrally moved between a clamping position and a release position in a moving plane arranged transversely to the theoretical central axis (S). The cheeks each have a support that jointly surround the rod-shaped profiled element in the clamped position and align the central axis (R) of the profiled elements along the theoretical central axis. The shape of the supports can be changed by an adjustable adjusting device, and the adjusting device reduces an offset of the theoretical central axis (S) from the central axis (R) of the profiled elements in the clamped position.
