Abstract

The invention is a boring machine including: a guide rail linearly extending in one direction; a main part slidably mounted on the guide rail; a sleeve extending from the main part in a plane substantially parallel to the guide rail; and a rotatable face plate mounted at a distal end of the sleeve; wherein a deflection-compensating wedge plate is provided between the distal end of the sleeve and the rotatable face plate.

First claim

The invention claimed is:

1. A boring machine comprising
a guide rail linearly extending in one direction;
a main part slidably mounted on the guide rail;
a sleeve extending from the main part in a plane substantially parallel to the guide rail;
a rotatable face plate mounted at a distal end of the sleeve;
wherein
a deflection-compensating wedge plate is provided between the distal end of the sleeve and the rotatable face plate, the deflection-compensating wedge plate comprising a first attachment surface configured to be attached to the sleeve and a second attachment surface configured to be attached to the rotatable face plate,
the first attachment surface and the second attachment surface are non-parallel;
an angle between the first attachment surface and the second attachment surface is determined depending on a supposed amount of deflection of the sleeve,
the deflection-compensating wedge plate and the sleeve are attached to each other by a first attachment measure,
the deflection-compensating wedge plate and the rotatable face plate are attached to each other by a second attachment measure, and
the sleeve and the rotatable face plate, which are not directly attached to each other, are attached to each other through the deflection-compensating wedge plate.

2. The boring machine according to claim 1 , wherein
the deflection-compensating wedge plate has a shape of an obliquely cut body of a right cylinder.

3. The boring machine according to claim 2 , wherein
the deflection-compensating wedge plate is arranged such that a line connecting a thinnest part of the deflection-compensating wedge plate and a thickest part of the deflection-compensating wedge plate is in alignment with a vertical direction.

4. The boring machine according to claim 2 , wherein
the deflection-compensating wedge plate is arranged such that a line connecting a thinnest part of the deflection-compensating wedge plate and a thickest part of the deflection-compensating wedge plate makes a predetermined angle with a vertical direction.

5. The boring machine according to claim 4 , wherein
an angle in a horizontal plane of the sleeve with respect to the guide rail is changeable in the horizontal plane, depending on an interposed state of the deflection-compensating wedge plate, by pivoting the main part relative to the guide rail in the horizontal plane.

6. The boring machine according to claim 1 , wherein
the deflection-compensating wedge plate has a shape of an obliquely cut body of a polygonal prism.

7. The boring machine according to claim 6 , wherein
the deflection-compensating wedge plate is arranged such that a line connecting a thinnest part of the deflection-compensating wedge plate and a thickest part of the deflection-compensating wedge plate is in alignment with a vertical direction.

8. The boring machine according to claim 6 , wherein
the deflection-compensating wedge plate is arranged such that a line connecting a thinnest part of the deflection-compensating wedge plate and a thickest part of the deflection-compensating wedge plate makes a predetermined angle with a vertical direction.

9. The boring machine according to claim 8 , wherein
an angle in a horizontal plane of the sleeve with respect to the guide rail is changeable in the horizontal plane, depending on an interposed state of the deflection-compensating wedge plate, by pivoting the main part relative to the guide rail in the horizontal plane.

10. The boring machine according to claim 1 , wherein
the deflection-compensating wedge plate is arranged such that a line connecting a thinnest part of the deflection-compensating wedge plate and a thickest part of the deflection-compensating wedge plate is in alignment with a vertical direction.

11. The boring machine according to claim 1 , wherein
the deflection-compensating wedge plate is arranged such that a line connecting a thinnest part of the deflection-compensating wedge plate and a thickest part of the deflection-compensating wedge plate makes a predetermined angle with a vertical direction.

12. The boring machine according to claim 11 , wherein
an angle in a horizontal plane of the sleeve with respect to the guide rail is changeable in the horizontal plane, depending on an interposed state of the deflection-compensating wedge plate, by pivoting the main part relative to the guide rail in the horizontal plane.

13. The boring machine according to claim 1 , wherein
the deflection-compensating wedge plate comprises a first half deflection-compensating wedge plate and a second half deflection-compensating wedge plate, both of which have the same inclined angle to each other.

14. The boring machine according to claim 13 , wherein
the first half deflection-compensating wedge plate is arranged such that a line connecting a thinnest part of the first half deflection-compensating wedge plate and a thickest part of the first half deflection-compensating wedge plate is deflected by a predetermined angle in a clockwise direction from a vertical direction, and
the second half deflection-compensating wedge plate is arranged such that a line connecting a thinnest part of the second half deflection-compensating wedge plate and a thickest part of the second half deflection-compensating wedge plate is deflected by the predetermined angle in a counterclockwise direction from the vertical direction.

15. The boring machine according to claim 1 , wherein
a cutting tool, which protrudes from the rotatable face plate in a substantially radial direction of the rotatable face plate, is mounted on the rotatable face plate via a U-axis controlling mechanism which can extend and retract in a radial direction of the rotatable face plate.
