Abstract

When transporting and positioning parts into mating engagement with fixtures, it is mandatory that a system for transport be devised that accurately and repetitively positions the part in the fixture, otherwise jam-ups and down time of the machine occurs. The repetitive indexing of the transport system, therefore, must take into account the wear tolerances and eliminate, where possible, play in the system.

Nest Table Rotary Drive

When transporting and positioning parts into mating engagement with fixtures, it is mandatory that a system for transport be devised that accurately and repetitively positions the part in the fixture, otherwise jam-ups and down time of the machine occurs. The repetitive indexing of the transport system, therefore, must take into account the wear tolerances and eliminate, where possible, play in the system.

As illustrated, a main shaft 10 is driven for imparting rotation to a driver gear 11 which connects to a gear 12 having a cam 13 projecting from the upper surface thereof. The cam 13 is adapted for registration in cam followers 14 which project radially from the central portion or hub 15 of a Geneva intermittor
16. A locking hub 17, projecting from the upper portion of the gear 12, registers during dwell portions of the Geneva intermittor 16, with scallops 18 in the periphery of the intermittor. The accurate dimensioning of the hub 17 and scallops compensates for any misalignment which may occur due to wear of the cam 13 or followers 14. The nest or table may circumscribe and be driven directly from the hub 15.
