Abstract
A clamping fixture for clamping a component, in particular a workpiece or tool, having a number of clamping jaws, distributed along a periphery, which are connected by appropriate elastic flexural webs to a main body, wherein the clamping jaws are adjustable by an axially movable actuating device in a radial direction from a release position into a holding position, which clamping fixture is characterized in that the flexural webs, in their release position, are inclined in relation to an axially parallel direction radially in a direction of their respective holding positions.
Claims14
A clamping fixture (1, 1′) for clamping a component (14), comprising a number of clamping jaws (4), distributed along a periphery, which are connected by elastic flexural webs (5) to a main body (2), an axially movable actuating device (8, 12) that adjusts a position of the clamping jaws in a substantially radial direction from a release position into a holding position, the axially movable actuating device applies a radial clamping force that is directed against the spring force of the flexural webs to the jaws during clamping, wherein the flexural webs (5), in the release position, are inclined in relation to an axially parallel direction radially in a direction of the holding positions, and an axial contact surface (2′) which is fixed in relation to the main body (2) and against which the component (14), upon being clamped, is adapted to encounter an axial contact pressure force, the axially movable actuating device comprises an actuating element (8), which, when moved in an axial actuating direction, applies a radial clamping force to the clamping jaws (4), and an elastic element (12), which, upon axial compression by the actuating element (8), undergoes a radial change in dimension to apply a radial clamping force to the clamping jaws (4).
