Embodiment Construction

[0037] figure 1 and 2 An exemplary embodiment of a coupling device 1 according to the invention is shown. The coupling device 1 serves to couple a hollow shank 2 to a receptacle 3 of a power tool. A tool (not shown) can be accommodated in the hollow shank 2 .

[0038] The receptacle 3 is axially penetrated by a bore in which the tie rod 4 is mounted displaceably in its longitudinal direction. The tie rod 4 has a head 4a at its front end.

[0039] The tie rod 4 is designed as a hollow body, wherein the guide 5 of the hollow shank 2 protrudes into the hollow body. In this way the tie rod 4 can slide on the guide 5 and thus be guided forcibly.

[0040] The coupling device 1 also has a clamping jaw 6 , wherein a part of the clamping jaw 6 is mounted in a sleeve 7 arranged in the receptacle 3 . The clamping pliers 6 can be moved between the clamped position and the released position by moving the pull rod 4 .

[0041] figure 1 The clamping jaw 6 is shown in its clamped posi...

Abstract

The invention relates to 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 betweentwo adjacent clamping segments is provided to extend in the longitudinal direction of the latter.

Description

technical field [0001] The invention relates to a coupling device according to the preamble of claim 1 . Background technique [0002] Such a coupling device is known from EP 1 837 107 B1. The coupling device serves to couple a hollow shank to a receptacle provided on the power tool side and comprises clamping jaws having individual clamping segments and having an annular collar with a wedge-shaped annular surface at the end of the outer circumference . In addition, a tie rod is provided with a head which has a radial projection which is pressed against the respective clamping section for clamping, wherein the clamping section is displaced radially outwards into the hollow shank hollow handle. [0003] On the other end opposite the annular flange, the clamping jaw has a suspension flange with a radial face which presses onto a fixed axial support of a part of the receiving portion. The clamping pliers are formed in one piece and are provided on the rear with an end-side ...
