Abstract

The apparatus shown automates the installation of a retroreflector on a disk drive actuator during the servo write process. The retroreflector is mounted in an opening 1 at one end of a long rectangular bar 2. A spring loaded expanding arbor 3 is press fit into the other end of the bar 2. An air cylinder 4 is used to release the arbor 3 by driving the tapered mandrel 5 out of the arbor allowing the outer diameter of the arbor 3 to spring to a slightly smaller diameter. The arbor 3 is then placed in an opening in shaft 6 of the magnetic disk drive actuator assembly 10. The air cylinder 4 is released and the tapered mandrel 5 is pulled into the arbor 3 by belleville spring washers 7, expanding arbor 3 to fit the product shaft 6 inner diameter 9.

Automated Retroreflector Attachment

The apparatus shown automates the installation of a retroreflector on a disk drive actuator during the servo write process. The retroreflector is mounted in an opening 1 at one end of a long rectangular bar 2. A spring loaded expanding arbor 3 is press fit into the other end of the bar 2. An air cylinder 4 is used to release the arbor 3 by driving the tapered mandrel 5 out of the arbor allowing the outer diameter of the arbor 3 to spring to a slightly smaller diameter. The arbor 3 is then placed in an opening in shaft 6 of the magnetic disk drive actuator assembly 10. The air cylinder 4 is released and the tapered mandrel 5 is pulled into the arbor 3 by belleville spring washers 7, expanding arbor 3 to fit the product shaft 6 inner diameter 9. The air cylinder 4 is removed and the retroreflector arm assembly is free to rotate with the actuator shaft 6 on the actuator bearings 8 and can be used to close the loop on a laser- controlled access system.
