Problems solved by technology

Another disadvantage is that the radial stiffness of this construction is insufficient, since the shrink ring that fits over the clamping sleeve is not in contact with the chuck and therefore cannot support the clamping sleeve

Embodiment Construction

[0011] The drawing shows an embodiment of a chuck 1 according to the invention. This chuck 1 comprises a basic body 2 made of a dimensionally stable material, which has a fixed cone 3 in a known manner at the end on the left in the figure, for clamping in a spindle driven to rotate in the machine tool . At the other end of the base body 2 there is a connecting rod 4 with a central receptacle 5 into which a tool, for example a cylindrical shank such as a drill or milling cutter, can be inserted. An annular cavity or an annular groove 6 is formed in the connecting rod 4 , which surrounds the mounting seat 5 and is oriented coaxially therewith. The annular groove 6 whose axial length is roughly equivalent to the required clamping area is bounded by a relatively thin inner wall (the clamping sleeve 7 ) towards the mounting seat 5 and by the base body 2 radially outwards. The wall of the substrate is bounded, and the wall thickness of the base body is many times larger than the w...

Abstract

The invention relates to a clamping chuck comprising a chuck body (2) made of a dimensionally stable material (v) on which a clamping sleeve (7) is provided that forms a central receiver (5) for a workpiece or tool which is to be clamped. In addition, the clamping chuck is equipped with clamping means (8) which are provided for fixing the part to be clamped inside the receiver (5) while causing the clamping sleeve (7) to elastically deform. An annular groove (6) is provided in the clamping body (2).

Description

technical field [0001] The invention relates to a chuck comprising a chuck head made of a shape-stable material and a clamping device, a clamping sleeve is arranged on the chuck, which constitutes a grip for a workpiece or tool to be clamped The central mounting seat, the clamping device is used to fix the component to be clamped in the mounting seat under the elastic deformation of the clamping sleeve. Background technique [0002] Such a chuck is known, inter alia, from WO 98 / 32563, which is used, for example, to fasten a tool holder, such as a drill holder or milling cutter holder, to a corresponding machine tool spindle. It consists of a base body made of dimensionally stable material, which has a fastening cone at one end for clamping in a rotationally driven spindle of the machine tool. A thin-walled clamping sleeve is provided at the other end of the base body, which forms an essentially cylindrical receptacle for the component to be clamped and has an outer surface ...
