Abstract
A tool assembly has a tool holder having a holder support face, a clamping dog having a dog surface spaced from and facing the holder support face, and a tool between the holder and the dog and having an end cutting edge, a face directly confronting the support face, and a surface directly confronting the dog surface. One of the surfaces is formed with a recess and the other surface is formed with a bump engageable in the recess. The dog surface can be pressed in a clamping direction generally perpendicular to the faces and surfaces toward the support surface and to clamp the tool between the dog and the support. The bump and recess are so dimensioned that they engage each other at at least three locations spaced from one another perpendicular to the clamping direction.
Claims19
A tool assembly comprising:
- a tool holder having a holder support face;
- a clamping dog having a dog surface spaced from and facing the holder support face;
- a tool between the holder and the dog and having at least one end cutting edge, a face directly confronting the holder support face, and a surface directly confronting the dog surface, one of the surfaces being formed with at least one recess and the other surface being formed with at least one bump engageable in the recess;
- and
- tightening means engaged between the holder and the dog for pressing the dog surface in a clamping direction generally perpendicular to the faces and surfaces toward the support surface and thereby clamping the tool between the dog and the support, the bump and recess being both substantially part-spherical, the bump having a larger radius of curvature than the recess and engaging the recess in all-around annular contact.
A tool assembly comprising:
- a tool holder having a holder support face;
- a clamping dog having a dog surface spaced from and facing the holder support face;
- an elongated tool extending along a longitudinal axis between the holder and the dog and having:
- a face directly confronting the holder support face, and a surface directly confronting the dog surface, one of the surfaces being formed with a recess and the other surface being formed with a bump engageable in the recess, and
- a lateral projection extending angularly outwardly from the tool and formed with a one side having an end cutting edge and a second side opposite the one side and formed with a back cutting edge, said back and end cutting edges being bridged by a side cutting edge ;
- and
- tightening means engaged between the holder and the dog for pressing the dog surface in a clamping direction generally perpendicular to the faces and surfaces toward the support surface and thereby clamping the tool between the dog and the support, the bump and recess being so dimensioned that they engage each other at at least three locations spaced from one another perpendicular to the clamping direction.
A tool assembly comprising:
- a one-piece tool holder having a flat holder support face;
- a clamping dog having a flat dog surface defined between a plurality of respective peripheral edges and spaced from and facing the flat holder support face;
- a tool between the holder and the dog and having an end cutting edge, a tool flat face directly confronting the flat support face, and a tool flat surface defined between said cutting edge and a respective plurality of peripheral edges and directly confronting the dog surface, one of the flat surfaces being formed with a recess and the other flat surface being formed with a bump engageable in the recess, said recess and bump being spaced inwardly from the peripheral edges of the respective surfaces;
- and
- tightening means engaged between the holder and the dog for pressing the dog surface in a clamping direction generally perpendicular to the flat faces and surfaces toward the support surface and thereby clamping the tool between the dog and the support, the bump and recess being substantially part-spherical and engaging each other in all-around annular contact plane lying perpendicular to the clamping direction.
