Abstract
A self-aligning multi-tool for use in a punch press having a ram. The multi-tool includes a housing carrying a striker and a magazine bearing a plurality of circumferentially spaced tools and rotatable with respect to the housing so as to bring a single desired tool into alignment with the striker. The housing has a striking surface adapted to be engaged by the ram of a punch press and configured to rotationally lock to the ram when correctly rotationally aligned therewith to prevent the housing from rotating as the magazine is rotated. The housing is provided with at least one alignment pin having a tapered cam surface and positioned such that the ram will contact and cam against the tapered cam surface of the pin as the ram approaches the striking surface if the machine ram and the striking surface are rotationally mis-aligned so as to urge the housing to rotate into correct alignment with the ram to enable rotational locking therebetween.
