A quick disconnect hub (50) which is secured to the motor drive shaft (62) received a high pitch threaded pad driver disk (40) to which a burnishing pad (30) is mounted. The hub (50) includes a conically tapered surface (45), as does the driver disk (40) for centering. A spring-loaded locking pin (84) extends between the burnishing motor (60) and selectively locks the drive hub (50) against rotation for removal of the driver disk by rotating approximately one or two times, thus allowing the removal of the pad driver (40) from the motor and allowing the centered mounting of the burnishing pad to the driver remote from the machine. In a preferred embodiment of the invention, an interlock switch (90) is coupled to the spring-loaded locking pin (84) such that, when the hub is locked against rotation for removal of the driver disk, the switch prevents inadvertent activation of the motor when the hub is locked. |
