US 12,583,068 B2 · Clamping arrangement

Abstract

A clamping arrangement has a clamping device is fastened fastenable on a clamping base, and a clamping element able to be tightened thereon. The clamping device has a clamping module with clamping members that can be fixed by a fixing element on the clamping base, wherein the fixing element is configured such that the clamping module is fixed in the X-Y plane in a floating manner. The clamping module is displaceable in the fixed state of the fixing element with respect to the fixing element in the X-Y plane, but is non-displaceable in the Z-direction. The fixing element is provided with Z-support surfaces for the clamping element. The clamping arrangement is particularly suitable for a large clamping system, so that thermally caused dimension changes of the workpiece carrier with respect to the clamping base can be equalized with repeatable accuracy, without the clamping system being over-constrained geometrically/mechanically in the X-Y plane.

Dependent claims

A clamping arrangement having a clamping device able to be fastened on a clamping base and a clamping element able to be tightened on the clamping device, wherein the clamping device comprises:

a clamping module including clamping members for engaging the clamping element to tighten the clamping element on the clamping device;
and
a fixing element configured to fix the clamping module on the clamping base, wherein the fixing element is configured such that the clamping module can be fixed, in a fixed state of the fixing element, in an X-Y plane, defined by an upper side of the clamping base, in a displaceable manner on the clamping base,
wherein the fixing element has centering grooves or centering cams and the clamping element has centering cams or respectively centering grooves, configured in a corresponding manner thereto, for centering the clamping element with respect to the fixing element in the X-Y plane in one direction.

A clamping arrangement, having a clamping device able to be fastened on a clamping base and a clamping element able to be tightened on the clamping device, wherein the clamping device comprises:

a clamping module including clamping members for engaging the clamping element to tighten the clamping element on the clamping device;
and
a fixing element configured to fix the clamping module on the clamping base, wherein the fixing element is configured such that the clamping module can be fixed, in a fixed state of the fixing element, in an X-Y plane, defined by an upper side of the clamping base, in a displaceable manner on the clamping base,
wherein the clamping module has a spring-loaded actuating piston, which is arranged for actuation of the clamping members axially movably in the interior of the clamping module, and
wherein the actuating piston has depressions running in the Z-direction, relative to the X-Y plane, which are coordinated with the clamping members such that on tightening of the clamping element an enlarged support surface is brought about between the respective clamping member and the actuating piston.
