Abstract

Mounting assemblies for cutting tools are disclosed that include a base and an adapter block. Mounting assemblies are provided with self-fixturing features to provide a desired mounting position and to restrict movement of the adapter block with respect to the base prior to bonding. The self-fixturing features provide the ability to perform repeatable and consistent bonding of the adapter block to the base.

First claim

What is claimed is:

1. A mounting assembly for a cutting tool comprising:
a base comprising a holder receiving surface including at least one planar intersection and a front planar intersection; and
an adapter block, the adapter block comprising:
an adapter block body having a top surface and a mounting surface;
at least one alignment protrusion tab extending from the mounting surface structured and arranged to engage the at least one planar intersection of the base; and
at least one alignment tab extending from the mounting surface structured and arranged to engage the front planar intersection of the base,

wherein the front planar intersection is a mounting groove recessed in the holder receiving surface and extends from a front edge of the holder receiving surface to a clearance opening.

2. The mounting assembly for a cutting tool of claim 1 further comprising a first planar intersection extending from a first side edge of the holder receiving surface to the clearance opening, a second planar intersection extending from the clearance opening to a second side edge of the holder receiving surface.

3. The mounting assembly for a cutting tool of claim 1 , wherein the holder receiving surface comprises a first mounting region extending from a rear edge of the holder receiving surface of the planar intersection, and a second mounting region extending from the planar intersection to a front edge of the holder receiving surface.

4. The mounting assembly for a cutting tool of claim 3 , wherein the first mounting region comprises a first rear planar face and a second rear planar face, and the second mounting region comprises a first front planar face and a second front planar face.

5. The mounting assembly for a cutting tool of claim 4 , wherein the front planar intersection is between the first front planar face and the second front planar face of the second mounting region.

6. The mounting assembly for a cutting tool of claim 1 , wherein the mounting surface comprises a rear base engagement region extending from a rear edge of the mounting surface to a first base engagement region, the first base engagement region extending from the rear base engagement region to the at least one alignment protrusion; and
a front base engagement region extending from the at least one alignment protrusion to a front edge of the mounting surface.

7. The mounting assembly for a cutting tool of claim 6 , wherein the first base engagement region comprises a first planar face and a second planar face, and the front base engagement region comprises a first front planar face and a second front planar face.

8. The mounting assembly for a cutting tool of claim 7 , wherein the first planar face of the first base engagement region of the adapter block is structured and arranged to correspond to the first rear planar face of the first mounting region of the base, the second planar face of the first base engagement region of the adapter block is structured and arranged to correspond to the second rear planar face of the first mounting region of the base, the first front planar face of the front base engagement region of the adapter block is structured and arranged to correspond to the first front planar face of the second mounting region of the base, and the second front planar face of the front base engagement region of the adapter block is structured and arranged to correspond to the second front planar face of the second mounting region of the base.

9. The mounting assembly for a cutting tool of claim 7 , wherein the first planar face of the first base engagement region of the adapter block is offset from the first rear planar face of the first mounting region of the base, the second planar face of the first base engagement region of the adapter block is offset from the second rear planar face of the first mounting region of the base, the first front planar face of the front base engagement region of the adapter block is offset from the first front planar face of the second mounting region of the base, and the second front planar face of the front base engagement region of the adapter block is offset from the second front planar face of the second mounting region of the base.

10. The mounting assembly for a cutting tool of claim 1 , wherein the at least one alignment protrusion of the adapter block extends from a first side to a second side of the mounting surface of the adapter block.

11. The mounting assembly for a cutting tool of claim 1 , wherein the at least one alignment tab is centrally located between a first front planar face and a second front planar face of a front base engagement region.

12. The mounting assembly for a cutting tool of claim 1 , wherein the adapter block comprises a cutting tool receiving opening extending from the top surface to the mounting surface.

13. The mounting assembly for a cutting tool of claim 1 , wherein a bottom surface of at least one the alignment protrusion contacts the planar intersection of the base and a bottom surface of the at least one alignment tab contacts the front planar intersection of the base.

14. The mounting assembly for a cutting tool of claim 1 wherein the at least one alignment protrusion has an extension distance less than a distance between the top surface and a planar face of the mounting surface.

15. The mounting assembly for a cutting tool of claim 2 , wherein the first planar intersection and the second planar intersection are mounting grooves recessed in the holder receiving surface; and wherein the at least one alignment protrusion of the mounting adapter block is structured and arranged to be received within the first and second planar intersections.

16. An adapter block for a mounting assembly for a cutting tool comprising: an adapter block body having a top surface and a mounting surface opposite the top surface;
at least one alignment protrusion extending from the mounting surface structured and arranged to engage a first planar intersection of a base block; and
at least one alignment tab extending from the mounting surface structured and arranged to engage a front planar intersection of the base block,
wherein the mounting surface comprises a front base engagement region extending from a front edge of the mounting surface to the at least one alignment protrusion and a first base engagement region extending from the at least one alignment protrusion.

17. The adapter block of claim 16 , wherein the at least one alignment protrusion has an extension distance less than a distance between the top surface and a planar face of the mounting surface.

18. The adapter block of claim 16 , wherein the at least one alignment tab is centrally located between a first front planar face and a second front planar face of a front base engagement region of the mounting surface of the adapter block.

19. The adapter block of claim 16 , wherein the adapter block comprises a cutting tool receiving opening extending from the top surface to the mounting surface.

20. A mounting assembly for a cutting tool comprising:
a base comprising a holder receiving surface including a front planar intersection; and
an adapter block, the adapter block comprising:
an adapter block body having a top surface and a mounting surface;
at least one alignment tab extending from the mounting surface structured and arranged to engage the front planar intersection of the base,

wherein the front planar intersection is a mounting groove recessed in the holder receiving surface and extends from a front edge of the holder
