ABSTRACT:
A machine tool is provided with a traversing work table that has a mounting plate supported for vertical reciprocation and rotary indexing movement. A pallet is supported on the mounting plate and releasably locked to it by a bayonet connection with a clamp ring which is selectively rotatable in the mounting plate; and the pallet also has an annular toothed coupling meshed with a segmented annular toothed coupling in the base. Rotary indexing is permitted by elevating the mounting plate only enough to unmesh the toothed coupling. Elevating the mounting plate to a higher level releases the clamp ring from the mounting plate, and at that level the operation of a pallet changer rotates the clamp ring to release the pallet for removal from the mounting plate. Further, a rotatable cover has flanges that are normally between the segments of the toothed coupling on the base, and the cover rotates simultaneously with the clamp ring so the flanges overlie the toothed coupling segments during pallet changing.
