Abstract

A positioning device for chip removing tools includes a tool holder receiver aligned with a positioning mechanism such as an engagement or index groove. A tool holder is aligned with the tool holder receiver at an angular position. A tool is aligned with the tool holder at another angular position.

Claims

1. A positioning device for chip removing tools, comprising a tool holder having a first positioning means, the first positioning means being in the form of at least one of an engagement and index groove, wherein a tool holder receiver has a second positioning means, such that engagement of the first and second positioning means predetermines a first angular position of the tool holder with reference to the tool holder receiver, wherein the tool holder is aligned in the tool holder receiver with a common longitudinal axis of the tool holder and tool holder receiver being along a first axis, wherein a tool receiver fixes a tool in a second annular position with respect to the tool receiver, wherein the tool is aligned with a longitudinal axis of the tool being along a second axis and the tool receiver is moveable with respect to the tool holder receiver, so that the tool is insertable into the tool holder, wherein, when inserting the tool into the tool holder, the tool holder receiver and the tool receiver are disposed relative to each other so that the first axis and the second axis are aligned and the second annular position is defined with reference to the first angular position, wherein the tool receiver is disposed at a column, the column being aligned along a third axis, wherein the tool receiver is moveable along the column, and wherein the column is rotatable around a longitudinal axis of the column.

2. A positioning device according to claim 1, wherein the first axis, the second axis, and the third axis are parallel to each other.

3. A positioning device according to claim 1, wherein the tool receiver is disposed at the column pivotable around the third axis, and thus the tool is pivotable from a position, in which the first axis and the second axis are not identical, into a position, in which the first axis and the second axis are identical.

4. A positioning device according to claim 1, wherein the tool receiver is movable with reference to the column, so that the distance of the second axis and the third axis can be varied, and thus the tool can be moved from a position, in which the first axis and second axis are not identical, into a second position, in which the first axis and the second axis are identical.

5. A positioning device according to claim 1, wherein the column is moveable with reference to the tool holder receiver, or the tool holder receiver is moveable with reference to the column, so that the distance of the first axis and the third axis is variable and thus the tool is moveable from a position, in which the first axis and the second axis are not identical, into a second position, in which the first axis and the second axis are identical.

6. A positioning device according to claim 1, wherein at the tool receiver at least one stop element is provided, the at least one stop element provides at least one stop for the tool, the at least one stop determines or defines the second angular position of the tool with reference to the tool receiver.

7. A positioning device according to claim 6, wherein the stop element comprises stops for right and left facing tools, and one of these stops for the right and left facing tools respectively can be brought into contact with the tool.

8. A positioning device according to claim 6, wherein the second angular position is predetermined by the at least one stop by means of a micrometer screw.

9. A positioning device according to claim 6, wherein the second angular position is determined by the at least one stop by means of a dial indicator.

10. A positioning device according to claim 6, wherein calibration elements are provided, which can be brought into contact with at least one the stop in order to calibrate a position of the at least one stop with reference to the tool receiver.

11. A positioning device according to claim 6, wherein the at least one stop element is moveably disposed on the tool receiver with reference to the tool.

12. A positioning device according to claim 1, wherein the tool is mounted in the tool receiver by means of at least one clamping band, a clamping bar with fixation screw, a magnet, or other mounting means.

13. A positioning device according to claim 1, wherein the tool holder receiver is rotatably mounted on a base plate.

14. A positioning device according to claim 1, wherein the tool holder receiver can be adapted to various tool holders, or can be replaced.

15. A positioning device according to claim 1, wherein the positioning device is provided as a fixed component, or as replaceable auxiliary equipment of a shrinking device or of a preadjustment device.
