Fixturing Device for Holding Photoconductor Drums

      Disclosed is a dual-function device for holding a
photoconductor drum as it moves from station to station in the
manufacturing process.  This device can hold the drum with or without
an end cap installed.

      As shown in the figure, the device has two key features: a
large diameter segmented disc and a small diameter segmented post.
The large disc holds the drum without the end cap installed, and the
small post holds the drum with the end cap installed.

      The segmented disc has angled sides that allow the inner bore
of the drum to engage the holder.  As the drum is pushed down
further, the segmented sections deflect and allow the angled sides to
go to a vertical position.  These sides engage the inner bore and
hold the drum securely.  The material used in this part is
polyphenylene sulfide.  It is reinforced with carbon fibers and has a
high modulus of elasticity for good spring characteristics.  It is
also conductive to dissipate static charge.  The open design allows
good ultrasonic cleaning action of the inside diameter of the drum.

      The small diameter post locates in the center hole of the end
cap.  It has four segments created by two narrow vertical and
perpendicular slots that bisect at the center of the post.  It has
angled sides that allow smooth engagement into the end cap, and
maximum holding after the drum is pressed onto the post.  This
provides maximum surface contac...
