摘要： A method and apparatus for automated valve spring assembly includes a head assembly with elongated passageways that movably support a pair of retainer keys. A pair of control members selectively close off the passageways. The head assembly further includes a moveable divider plate and a pair of jaws. A push member or rod closes off the passageways by shifting the control members upon movement of the pushrod. The pushrod also slides the retainer keys such that the retainer keys contact tapered inner surfaces of the jaws and rotate the jaws outwardly. The retainer keys are thereby axially positioned relative to the end of a valve stem. The retainer plate is then retracted, and the jaws shift inwardly and push or position the retainer keys on the valve stem.
