Abstract

Various embodiments include a structure for positioning a tool on an elongated recess of a workpiece, wherein the elongated recess extends along a first longitudinal axis and has end surfaces on two end faces. The structure may include a plate having a cutout extending along an axis; a centering device; and a clamping device fixedly connected to the plate and the centering device. The cutout, when the second longitudinal axis is aligned parallel to the first longitudinal axis, enframes the elongated recess. The centering device includes a centering jaw movable within the cutout along the second longitudinal axis and also movable into and out of the elongated recess. The clamping device, on the side of the plate facing the elongated recess, includes clamping jaws movable along the second longitudinal axis to come into mechanical contact with one of the end surfaces of the end faces of the elongated recess.

First claim

The invention claimed is:

1. A structure for the positioning and fastening of a tool on an elongated recess of a workpiece, wherein the elongated recess extends along a first longitudinal axis and has end surfaces on two end faces, the structure comprising:
a plate having a cutout extending along a second longitudinal axis;
wherein the cutout, when the second longitudinal axis is aligned parallel to the first longitudinal axis, enframes the elongated recess;
a centering device; and
a clamping device fixedly connected to the plate and the centering device;
wherein the centering device includes a centering jaw movable within the cutout along the second longitudinal axis and also movable into and out of the elongated recess;
wherein the clamping device, on the side of the plate facing the elongated recess, includes clamping jaws movable along the second longitudinal axis to come into mechanical contact with one of the end surfaces of the end faces of the elongated recess.

2. The structure as claimed in claim 1 , wherein the centering jaw extends in cross section defined perpendicular to the second longitudinal axis beyond the extent of the elongated recess perpendicular to the first longitudinal axis.

3. The structure as claimed in claim 1 , wherein the centering jaw comprises a wedge, a cone, a truncated cone, a semi-sphere, or a parallelepiped.

4. The structure as claimed in claim 1 , wherein the centering jaw can be moved perpendicularly to the plate or from one of the end faces of the first longitudinal axis into and out of the elongated recess.

5. The structure as claimed in claim 1 , wherein the two centering jaws create wedges corresponding to an opening angle of the elongated recess.

6. The structure as claimed in claim 1 , wherein the elongated cutout extends spatially along the second longitudinal axis beyond the length of the elongated recess along the first longitudinal axis; and
wherein the centering jaw moves out of the elongated recess and along the second longitudinal axis beyond the end surface outside the elongated recess.

7. The structure as claimed in claim 1 , wherein a spacing of two clamping jaws on two end faces is greater than a length of the elongated recess.

8. The structure as claimed in claim 1 , wherein mechanical contact of the clamping jaws with the end faces of the elongated recess is created by mechanical pressure and/or magnetic force.

9. The structure as claimed in claim 1 , wherein the clamping jaws can be rotatably adjusted around a vertical to the plate for adapting to an angle between the first longitudinal axis and a third longitudinal axis of a rotor shaft.
