Abstract
The invention relates to a tool components and a method of assembling tool components. One tool component comprises a central recess and a fastener. The recess is non-circular in cross-section. Another tool component has a central projection and a central threaded bore in its axially rear end. The projection is non-circular in cross-section.
Claims8
A tool component for a tool assembly, said component adapted to be connected to another element of the assembly and comprising a body defining a front-to-rear extending center axis, said body including a rearwardly facing surface and a truncated conical projection extending rearwardly from said rearwardly facing surface and adapted to be received in a correspondingly configured recess of the other element, a portion of said rearwardly facing surface disposed laterally outwardly of said projection defining a support surface engageable with the other element, said projection being non-circular in a cross-section taken perpendicular to said center axis so as to be rendered non-rotatable relative to the other element when received in the recess thereof, said projection including a rearwardly open hole extending along said axis, said hole being internally threaded and adapted to receive a threaded fastening bolt to draw said projection into the recess of the other element.
A tool component of a tool assembly, said component being a tool for chip removal, an adapter for a tool or a holder for a tool, said component having a central, truncated conical projection at an end thereof, a support surface adapted to abut an opposing surface of another element, and fastening means adapted to receive a fastener to connect said tool component to the other element, said component having a center axis, said attachment portion being non-circular in a cross-section taken perpendicular to the center axis, said projection provided with at least one slot which extends radially from an outer envelope surface of the projection to a central threaded bore of the projection and which extends longitudinally from a rear end of the projection and terminates short of said support surface of the component.
