HYDRAULIC CLAMPING DEVICE |
摘要 |
A hydraulic clamping device for the axial clamping of bodies of rotation, especially tools, onto a revolving mandrel is provided. It has a base body fixed to a mandrel and a rotary piston which is suspended in a floating manner inside the base body and is axially slidable relative to the base body via a closed-circuit hydraulic system and setscrews. The tool is tightly clamped in an axial direction. In order to improve the axial rigidity of the hydraulic clamping device, to provide a fast and directed adjustment of the concentricity during the clamping of the tool inside the device and to provide a radial freedom of play during operation, a sleeve fastened to the mandrel is provided to which the base body is attached. The sleeve is equipped with an elastic flange, a first face of which is engaged by the rotary piston and a second face of which is abuttable against said tool.
