Abstract
A spool (10) including a core (12) and end disks (18, 24) retained by tabs (16, 22) is assembled by sliding each end disk over the core into proximity with its associated tabs, contacting the end disk with at least a single point tool (106; 228-252) and rotating the tool to snap the disks past the tabs one by one. A transducer assembly (142-160) measures axial force applied to the core to detect successful installation of each end disk.
Claims14
Apparatus for assembling an arbor having an axis and a plurality of radially extending protuberances for positioning a part and a part having a through opening for axially receiving the arbor, the apparatus comprising:
- means for holding the arbor;
- means for sliding the part onto the arbor;
- means for applying axial force to the part at least at one point of application spaced radially from the axis while moving the point around the axis, thereby moving the part past the protuberances;
- means for measuring axial force applied to the arbor as an indication that the pan has passed the protuberances;
- and
- means for ceasing the applying of force in response to the indication.
