Abstract:
A piston apparatus for positioning parts for mounting on workpieces, which comprises:(a) a piston cylinder having a first end and a second end;(b) a piston rod having a first end and a second end with the first end slidably mounted in the piston cylinder for movement between the ends of the piston cylinder such that the piston rod moves along a longitudinal axis of the cylinder, until the second end of the piston rod is inserted into an opening in the parts; and(c) an electromagnetic means mounted on the piston cylinder adjacent the second end of the piston cylinder for magnetizing a portion of the piston rod adjacent the second end of the piston rod such that the parts are held adjacent the second end of the piston rod by magnetic attraction between the parts and the portion of the piston rod.
