ABSTRACT:
A rotary shuttle (10) for a machine tool (11) in which no power mechanism is required for moving the pallet (14, 15) with the workpiece off of the shuttle (10) and on to the machine tool worktable (13A) or for withdrawing a pallet (14, 15) with the completed workpiece on it off of the machine tool worktable (13A) and back on to the shuttle (14, 15). A rotatable shuttle (10) is presented with a workpiece support which can also be raised and lowered with pallets (14, 15), which in conjunction with an indexing table (13) moves workpieces between the worktable (13A) and a workpiece support (16, 19). A frame (66) of the shuttle mechanism (10) includes an offset rotatable section (65) which is arranged to extend over a portion (79) of the indexing table (13) with the shuttle mechanism (10) including support arms (16, 19) in conjunction with the offset rotatable section to extend over a portion of the indexing table (13). In this manner, the rotation as well as raising and lowering of the workpiece support can effect the placement of a workpiece from the workpiece support on to an indexing table as well as removal therefrom of the workpiece which has been operated on without the requirement of a power mechanism for moving a pallet (14, 15) between the workpiece support (16, 19) and the indexing table (13).
