Abstract
The invention relates to a clamping device which comprises a base, having a center holding fixture for a structural component to be clamped and a plurality of cavities arranged around the holding fixture. The base can be elastically deformed in such a manner by radial compressive forces applied from the outside in the area of the cavities that a structural component to be clamped can be inserted in the holding fixture and can be elastically returned to its former shape by reducing or releasing the radial forces, thereby establishing a pressure connection with the structural component to be clamped. The invention is characterized in that centrifugal counterweights are provided inside the cavities.

A clamping device with a base element (2) which has a central receptacle (3) for a component to be clamped and several cavities (4) around the receptacle (3), the base element (2) being elastically deformable by radial compressive forces (F) which are applied from the outside in the region of the cavities (3), such that a component to be clamped can be pushed into the receptacle (3) and by reducing or releasing the radial compressive forces can be elastically deformed back in order to create a pressure connection with the component to be clamped, wherein centrifugal force counterweights (5) are provided in the cavities (4), said centrifugal force counterweights (5) are formed integrally with the base element (2) and are connected in the region of the outer walls of the cavities (4) to the base element (2) by bar-like connection regions (6),
- wherein the bar-like connection regions (6, 8) between the base element (2) and the centrifugal force counterweights (5) are positioned approximately centrally in the cavities (4), as viewed in the circumferential direction.
A clamping device with a base element (2) which has a central receptacle (3) for a component to be clamped and several cavities (4) around the receptacle (3), the base element (2) being elastically deformable by radial compressive forces (F) which are applied from the outside in the region of the cavities (3), such that a component to be clamped can be pushed into the receptacle (3) and by reducing or releasing the radial compressive forces can be elastically deformed back in order to create a pressure connection with the component to be clamped, wherein centrifugal force counterweights (5) are provided in the cavities (4), said centrifugal force counterweights (5) are formed integrally with the base element (2) and are connected in the region of the outer walls of the cavities (4) to the base element (2), and
- wherein centrifugal force counterweights (5) are inserted as separate components into the cavities (4) and are designed and arranged such that bar-like connections regions (8) are formed between the centrifugal force counterweights (5) and the base element (2) in the region of the outer walls of the cavities (4) in which there is in particular direct contact between the base element (2) and the centrifugal force counterweights, and
- wherein the bar-like connection regions (6, 8) between the base element (2) and the centrifugal force counterweights (5) are positioned approximately centrally in the cavities (4), as viewed in the circumferential direction.
A clamping device, comprising
- a base element;
- a central receptacle formed in said base element for component to be clamped;
- a plurality of cavities symmetrically disposed around the receptacle, said cavities being formed in said base element;
- centrifugal force counterweights disposed in the cavities;
- bar-like connection regions connecting the centrifugal force counterweights to the base element in the region of radial outer walls of the cavities;
- wherein the base element elastically deformable by radial compressive forces (F) which are applied from the outside in the region of the cavities, such that the receptacle becomes larger and the component to be clamped can be pushed into the receptacle and by reducing or releasing the radial compressive forces can be elastically deformed back in order to create a pressure connection with the component to be clamped.
