Rotary work head assembly

摘要

A rotary work head assembly comprises a hub 1 carried by a drive shaft and a working head 10 coupled to the hub 1 for coaxial rotation. The coupling includes latching means 8 and is adapted to allow tilting of the working head 10 with respect to the hub 1. The latching means 8 is configured so that sufficient tilting serves to disengage the latching means 8 and therefore demount the working head 10 from the hub 1.
