Tool for forming a sidewall surface of a recess in a workpiece

摘要

A method of forming a joint between first and second workpieces generally consisting of forming a recess in one of such workpieces, provided with at least one side wall having a serrated cross-sectional configuration with inwardly projecting, distortable segments; providing a portion in the other of such workpieces, insertable into such recess, having a cross-sectional configuration sufficient to engage and distort such segments as such portion is inserted into such recess; and inserting such of the other workpiece into such recess, causing the segments to distort and thus provide an interference fit between such workpieces.

主权项

1. A tool, comprising:
an elongated body having a central axis, a proximal region, and a distal region; a plurality of recesses, wherein each recess is defined by one of a plurality of linearly displaced, continuous annular paths extending around a periphery of the elongated body at the distal region, wherein an entirety of each annular path (i) lies on a plane that is perpendicular to the central axis of the elongated body and (ii) is parallel to an entirety of each other path, and wherein each recess comprises:
a distal surface extending from the periphery of the elongated body towards the central axis of the elongated body in a direction perpendicular to the central axis of the elongated body; anda proximal surface sloping from the periphery of the elongated body towards the central axis of the elongated body and towards the distal surface, wherein each recess is positioned adjacent to at least one other recess such that the plurality of recesses cooperatively form a serrated periphery at the distal region, and wherein the proximal and distal surfaces meet at a point; and at least one groove intersecting at least one of the plurality of paths.
