Abstract:
A self-aligning multi-tool for use in a punch press having a ram, comprising a housing carrying a striker, 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, said housing having a striking surface adapted to be engaged by the ram of a punch press and said housing rotationally locking to the ram when correctly rotationally aligned therewith to prevent the housing from rotating as the magazine is rotated; said housing including 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.
