Abstract
A holding apparatus for an in particular dental workpiece includes a holding element and a fixing device. The workpiece can be fixed to the holding apparatus by a relative movement of the fixing device with respect to the holding element. The fixing device or the holding element has a split sleeve, and the inside surface of the split sleeve forms a clamping surface for the workpiece. Upon the relative movement of the fixing device with respect to the holding element, the workpiece can be braced against the holding device by the clamping surface.
Claims13
A holding apparatus for holding a workpiece, comprising:
- a holding element;
- and
- a fixing device, said holding element and said fixing device being configured to hold the workpiece due to a movement of said fixing device relative to said holding element;
- wherein one of said fixing device or said holding element comprises a split sleeve having a slit extending an entire axial length of said one of said fixing device or said holding element;
- and
- wherein said holding element and said fixing device have corresponding wedge surfaces, at least one of said corresponding wedge surfaces being inclined relative to a longitudinal axis of said split sleeve, said corresponding wedge surfaces being formed such that, upon the movement of said fixing device relative to said holding element along the longitudinal axis of said split sleeve, said corresponding wedge surfaces bear against each other to fix said fixing device against said holding element by wedging;
- and
- wherein an inside surface of said split sleeve forms a clamping surface for holding the workpiece such that, upon the movement of said fixing device relative to said holding element along the longitudinal axis of said split sleeve, the workpiece is held by said clamping surface.
