A clamping device 1a for clamping a work piece of a rotating spindle of a machine tool, in particular a balancer, wherein the clamping device comprises a base body 2, which is configured to be fixated at the spindle and which comprises at least one change body 1 which can be coupled to and decoupled from the base body 2, wherein the change body 1 and the base body 2 are supported coaxial to one another and clamped relative to one another in radial direction by roller elements 11, wherein each of the roller elements 11 is disposed in a gap between the base body 2 and the change body 1, which is configured as a wedge shaped gap and adapted to the respective roller element 11, so that the respective roller element can be moved along the wedge shaped gap, deeper into the wedge shaped gap, when the base body 2 and the change body 1 are connected to one another, so that the desired radial clamping is provided.
A clamping device (1a) for clamping a work piece at a rotating spindle of a machine tool, in particular a balancer, wherein the clamping device comprises a base body (2), which is configured to be fixated at the spindle and which comprises at least one change body (1) which can be coupled to and decoupled from the base body (2), wherein the change body (1) and the base body (2) are supported coaxially relative to one another and clamped relative to one another in radial direction by roller elements (11), wherein each of the roller elements (11) is disposed in a gap between the base body (2) and the change body (1), which is configured as a wedge shaped gap and adapted to the respective roller element (11), so that the respective roller element can be moved along the wedge shaped gap, deeper into the wedge shaped gap, when the base body (2) and the change body (1) are connected to one another, so that the desired clamping is provided in radial direction.
A clamping system for clamping a tool at a rotating spindle of a machine tool, in particular a balancer, wherein the clamping system comprises a base body, which is configured to be fixated at the spindle, and at least one tool holder, which can be coupled to the base body or decoupled from the base body, wherein the tool holder and the base body are supported coaxial relative to one another in completely coupled state, and clamped relative to one another in radial direction, wherein each of the roller elements is disposed in a gap between the base body and the tool holder, which gap is configured as a conical gap and adapted to the respective roller element, so that the respective roller element can be moved along the conical gap and deeper into the conical gap, when the base body and the tool holder are connected with one another, so that the desired clamping is provided in radial direction.
A clamping system for clamping a work piece at a rotating spindle of a machine tool, in particular a balancer, wherein the clamping system comprises a base body, which is configured to be fixated at the spindle and at least one tool holder which can be coupled to and decoupled from the base body, wherein the base body and the tool holder comprise conical surfaces corresponding to one another through which the base body and the tool holder are centered relative to one another, wherein the corresponding conical surfaces of the base body and the tool holder are also offset from one another in completely coupled state and the base body and the tool holder are supported coaxially relative to one another and clamped relative to one another substantially in radial direction by roller elements disposed between the conical surfaces.
