Abstract: A clamping chuck has a chuck body made of a dimensionally stable material, on which is provided a clamping sleeve that forms a central receptacle for a workpiece or tool that is to be clamped, and has a clamping mechanism for immobilizing in the receptacle the component that is to be clamped, while elastically deforming the clamping sleeve. There is configured in the chuck body an annular groove which surrounds the receptacle to form the clamping sleeve and is open toward the end face of the chuck body. The clamping mechanism includes a wedge ring that has a ring body and multiple clamping tongues arranged thereon, spaced apart from one another in the circumferential direction, and projecting substantially axially. The wedge ring possesses a cross section tapering in a wedge shape toward the free end, and it can be pressed axially into the annular groove while radially deforming the clamping sleeve.

Abstract: A joining system for repeatedly but securely joining two members, where one member is temporarily deformed during the joining process in such a way that an effective peripheral contour corresponds to the corresponding effective peripheral contour of the other member with a given tolerance, and after the two members have been positioned, a tight pressure fit of the two effective peripheral contours is established by at least partial elastic recovery of the deformable member. According to this invention, the original peripheral contour of the deformable member has some sections inside the peripheral contour of the other member and has some sections outside that peripheral contour. The deformation of at least one member takes place through the controlled action of radial compressive forces on certain sections of the peripheral contour of the deformable member. The tight mutual pressure fit of the two peripheral contours is achieved in predetermined peripheral sections by elastic recovery of the deformable member.

Abstract: A chucking tool for non-positive precision chucking of a part such as a workpiece or the shank of a tool, for example. The tool consists of a base body, an expansion sleeve that is detachably mounted on a part of the base body which is elastically deformable in the radial direction, and a device for introducing a hydraulic medium into a pressure space provided between the expansion sleeve and the wall of the base body. According to this invention, the expansion sleeve is made of a comparatively thick-walled thermoplastic material, at least in its radially deformable part. According to another feature of this invention, there is at least one groove-shaped hydraulic medium channel in the area of the surface pairing of the expansion sleeve and the base body and it can be acted upon by the supply of hydraulic medium, for example, with a manually operated piston-cylinder unit provided in the base body.

Abstract: The invention relates to an expansion chuck comprising a base, a thin-walled expansion sleeve that is disposed in a final axial zone of the base and forms a central seat for a component that is to be clamped, and a clamping ring which surrounds the expansion sleeve so as to form an intermediate annular pressure chamber and is screwed to the base. Said pressure chamber is filled with a hydraulic means while the expansion sleeve can be elastically deformed for fixing a component within the seat by axially displacing the clamping ring, said clamping ring being twisted in relation to the base such that the volume of the pressure chamber decreases. The inventive expansion chuck is characterized in that the pressure chamber is filled wit a hydraulic means while a sliding ring element is placed between the ela: pressure surface of the clamping ring in order to transmit an axial con clamping ring to the solid body.

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.
