Abstract
A ring expander and assembly machine, having a loading station, a spreading station and assembly station, is operable to expand a spiral retaining ring in place on a workpiece. Spiral retaining rings with locking tabs and slots are transported on a shuttle from the loading station to the spreading station, at which location, scraper blades and fulcrum cams cooperate to spread the ring and remove the tabs from the slots so that an expansible collar assembly can be used to expand the ring. A transporter moves the collar assembly with the ring to the assembly station where a stripper sleeve removes the ring from the collar assembly to the workpiece.
