A modular accessory for headstock/tailstock positioners gives robots from Motoman Inc., Dayton, Ohio, more flexibility for tooling changeover as compared to hard-mounted systems.

The MotoMount accessory includes a headstock fixture assembly, a compliant tail-stock bearing, and a tailstocktooling adapter. It retrofits onto existing installations of headstock/tailstock positioners and minimizes installation expense by eliminating the need for costly machine bases and surveying tools for precise headstock/tailstock alignment.

Up to a maximum of 2°, MotoMount eliminates the additional headstock bearing loads induced by tooling and headstock/tailstock misalignments. MotoMount also decreases movement forces on the headstock by 70% for 3-m spans and affords even higher reductions with wider spans. This improves headstock life by minimizing wear on the motor gears and bearings.

A simple procedure using the MotoMount system and a caliper provides sufficient alignment of typical floor-mounted headstock/tailstock assemblies. Future Motoman "World" solutions that include head-stock/tailstocks will feature MotoMount as standard equipment.
