Abstract

The invention relates to a clamping claw having a securing leg and a clamping leg for securing an object in a first recess of a support, with the clamping claw in the installed state being secured on the support by way of its securing leg by means of a bolt and clamping the object in the recess by means of its clamping leg. To split the application of axial force applied to an object by a clamping claw in part into an application of force that acts transversely thereto, the clamping claw includes two portions, namely a clamping base and a clamping finger, the clamping base sits on the support in the installed state of the clamping claw, the clamping finger has a securing leg and a clamping leg, and the installed state the securing leg sits on the clamping base over an oblique plane formed as a sliding surface and clamps the object with its clamping leg.

Claims (13)

1. A clamping claw comprising a securing leg and a clamping leg for securing an object in a first recess of a support, with the clamping claw in the installed state being secured on the support by way of its securing leg by means of a bolt and clamping the object in the recess by means of its clamping leg wherein

the clamping claw comprises a clamping base and a clamping finger,

the clamping base sits on the support in the installed state of the clamping claw,

the clamping finger has a securing leg and a clamping leg, and in the installed state the securing leg sits on the clamping base over an oblique plane formed as a sliding surface and clamps the object with its clamping leg, and

during clamping the bolt presses the securing leg of the clamping finger onto the clamping base and secures both on the support, wherein, as a result of the oblique plane that is formed as a sliding surface, the securing leg and thus the clamping leg of the clamping finger execute a lateral movement transversely in relation to the longitudinal axis of the clamping base.

2. A clamping claw according to claim 1 , wherein in order to secure the clamping base on the support in a secure manner with respect to rotation at least one projection that extends parallel to the longitudinal axis of the clamping base and engages into a longitudinal slot in the support that is matched thereto is arranged on the clamping base.

3. A clamping claw according to claim 1 , wherein the clamping base at its end that faces the securing leg of the clamping finger has an oblique plane that is formed as a sliding surface, and the securing leg of the clamping finger at its end that faces the clamping base likewise has an oblique plane that is formed as a sliding surface, and both sliding surfaces are matched to each other and are formed so that they slide one on top of the other.

4. A clamping claw according to claim 1 , wherein the clamping base in the installed state rests with a first guide surface against a second guide surface on the securing leg of the clamping finger so that the securing leg of the clamping finger is arranged on the clamping base in a secure manner with respect to rotation, but so that it can be displaced in the clamping direction.

5. A clamping claw according to claim 1 , wherein that the clamping base has a projecting flange with which the clamping base sits on a recess in the support in the installed state.

6. A clamping claw according to claim 1 , wherein the clamping claw is a part of a cutting tool for machining metallic materials, in which case the support is a gripping holder and the object is a cutting plate.

7. A clamping claw according to claim 1 , wherein that arranged on the clamping leg of the clamping finger directly or by way of a pressure plate there is a raised portion, like a cam for example, which in the installed state engages into a corresponding trough in the object or in the cutting plate.

8. A clamping claw according to claim 7 , wherein the raised portion or the cam on the clamping leg of the clamping finger is formed as a circular ring which in the installed state engages into an object or a cutting plate that has a spherical or circular raised portion and in so doing embraces the raised portion.

9. A clamping claw according to claim 2 , wherein the clamping base at its end that faces the securing leg of the clamping finger has an oblique plane that is formed as a sliding surface, and the securing leg of the clamping finger at its end that faces the clamping base likewise has an oblique plane that is formed as a sliding surface, and both sliding surfaces are matched to each other and are formed so that they slide one on top of the other.
