Embodiment Construction

[0032] figure 1 A side view of a preferred embodiment of a compression sleeve 10 according to the invention is shown. In this, the number of tabs 12 can be discerned, which (in the lower part of the view) gradually merges into the base part 14 . The pressure sleeve 10 is formed in one piece. This makes it possible to introduce the forces acting on the tab 12 during clamping into the base part 14 in a particularly simple manner. Furthermore, each tab 12 is fixed without play in a position predetermined by the structure. The compression sleeve 10 has twelve tabs 12 in the selected example. The results show that a particularly good clamping effect can be achieved with good positionability of the compression sleeve 10 by means of the 12 tabs 12 . However, in principle, the clamping effect can be achieved by 2 snap tongue elements, so under the conception of the present invention, the number of snap tongues in each group can also be selected to be greater than 2. How to specif...

Abstract

The disclosure relates to a clamping apparatus for fixing in a recess (38) of a component (40) and comprising a clamping sleeve which is connected to an inner component (52). A clamping mandrel (42) is movable relative to the clamping sleeve. The inner component (52) is guided at least partially in a housing and a workpiece carrier (60) may be attached on that side of the housing (22) which faces towards the recess (38). The housing (22) may be moved relative to the clamping mandrel (42) when the clamping sleeve is situated in a clamped position. The clamping mandrel (42) may be moved relative to the clamping sleeve by a first pressure medium for bracing purposes. The holding force of the clamping action may be adjusted by pressure in the first pressure medium. The housing (22) which carries the workpiece carrier (60) can be moved relative to the clamping mandrel (42) with the aid of a second pressure medium in the case of the clamping sleeve which is situated in the clamped position, that the force, with which the workpiece carrier bears against the component, can be regulated by way of a pressure in the second pressure medium, and that the pressures in the first and in the second pressure medium are regulated in such a way that the holding force is greater than the force for carrying out the relative movement between the housing (22) and the clamping mandrel (42).

Description

technical field [0001] The invention relates to a fastening device with a clamping sleeve for fastening in a groove, the clamping sleeve being connected to a component, wherein the clamping mandrel is movable relative to the clamping sleeve, wherein the component is at least partially guided into In the housing, wherein the assembly can be mounted on the side of the housing directed towards the recess, wherein the housing is movable relative to the clamping sleeve in the tightened position. Background technique [0002] A fastening element is known from publication DE 29 500 115 U1, by means of which a weight can be fastened in a bore of a component. To this end, a plurality of partial housings combined with O-rings interact with the fastening element. The fastening element is pressed into the partial housing for clamping by means of a diaphragm spring and fastened with constant force against the inner wall of the bore. However, the weight on the fastening element usually ...
