Abstract
A coupling device for coupling a hollow shaft taper to a receiver provided on the machine tool, having a collet and a tension rod by means of which the collet can be brought into a release position or a clamping position. The collet is embodied in one piece and has several clamping segments extending in its longitudinal direction. Upon moving the collet into the clamping position, said clamping segments are moved in a radial direction against spring forces exerted by the spring element. The spring elements are an integral part of the collet. Each spring element between two adjacent clamping segments is provided to extend in the longitudinal direction of the latter.
Claims13
A coupling device (1) for coupling a hollow shaft coupling (2) to a receiver (3) provided on the machine tool side, having a collet (6) and a tension rod (4) by means of which the collet (6) can be moved into a release position of a clamping position, with the collet (6) being embodied in one piece and having several clamping elements (8) extending in its longitudinal direction, with said clamping elements, upon moving of the collet (6) into the clamping position, being moved in a radial direction against spring forces exerted by the spring element (9), with the spring elements (9) being an integral part of the collet (6), characterized in that each spring element (9) is provided to extend between two adjacent clamping segments (8) in their longitudinal direction.
