Abstract:
1. An O-ring insertion device for applying an O-ring to a part, the O-ring device comprising: a piston having an O-ring engagement portion; an O-ring holder having a piston insertion hole therethrough; a part holder for holding the part spaced from the O-ring holder; the piston drives the O-ring engagement portion from an initial position through the piston insertion hole and into close proximity with the part defining a space between the part and the piston so that the piston and the O-ring engagement portion do not contact the part, and returns the piston and the O-ring engagement portion to the initial position; the piston further comprises an intermediate cylinder having a thin walled portion which in cooperation with the O-ring engagement portion is driven through the piston insertion hole to engage an O-ring supported by the O-ring holder concentric with the piston insertion hole; a piston housing containing the intermediate cylinder and O-ring engagement portion and the piston housing in cooperation with the thin walled portion of the intermediate cylinder applies the O-ring to a part supported on the part holder; and a drive device for driving the piston through the piston insertion hole in the O-ring holder and a pressure device for slidably displacing the intermediate cylinder and the O-ring engagement portion relative to the piston housing.
