ABSTRACT:
A machine tool wherein an annular gear is rotatable in a horizontal plane to carry a plurality of pallets between adjacent peripherally arranged machine stations. The gear is lowered as each machine station is attained by the entry of gear support bearings into recesses in the underside of the gear. The pallets are supported on the gear for limited vertical and horizontal movement, and lowering of the gear positions the pallet on an abutment surface in rough alignment with the machining station. As the gear is further lowered, it is spaced from the pallet so as not to interfere with independent positioning of the pallet by power actuated positioning means located at each machining station. Thus, the pallet can be adjusted independently of the gear when the gear is in its lowered position, yet is carried by the gear when the gear is in its elevated position. After the machining operation is completed, the pallet is released from its clamped position, the gear is raised to again support the pallet, and the gear is rotationally actuated to carry the pallet into rough alignment with the next successive machine station.
