ABSTRACT:
A tool changing mechanism for a machining center comprising arcuate shuttle path means including rail means having a uniform width with opposing sides and a gear track parallel to the rail, and a tool shuttle including a tool change arm, shuttle path engagement means including post means, means for mounting the post means on the tool shuttle for selective rotation about a vertical axis, a pair of guide rollers, means for mounting the pair of guide rollers on the post means with a selected spacing therebetween substantially equal to the rail width, whereby the pair of guide rollers will engage the opposing rail sides and selectively change their orientation to automatically maintain an orthogonal relation thereto while the shuttle traverses the arcuate shuttle path, a driven gear concentrically mounted for rotational movement relative to the post means about the post rotational axis and for engagement with the gear track, and means for driving the driven gear, whereby the shuttle may traverse the arcuate shuttle path maintaining the gear in continuous driving engagement with the gear track while the orientation of the guide rollers changes maintaining continual orthogonal engagement with the opposing rail sides.
