A machine for finishing eccentric shafts includes a flow-through quick change arbor with axially spaced radial ports. Hollow adapter hubs are spaced along the shaft in register with the ports. Axial spacing is obtained with cylindrical spacers and discs on each side of each hub. A nut on one end of the shaft clamps stacked hubs, discs and spacers together for rotation with the shaft. Each hub supports two side-by-side finishing tools, each of which includes a ring from which the finishing material extends in a radial array. Each hub on its face includes a set of diametrically opposite bayonet slots which interfit with drive lugs on the inside of the rings. The slots extend in both circumferential directions from the axially extending entrant portions with the ends engaging the lugs for rotation in either direction while providing ease of mounting and replacement. The entrant portions on each side of the hub are aligned and connected so that a tool ring may be mounted from either side of the hub. The hub includes radial ports between the rings so that fluid may flow from the shaft through the hub and between the side-by-side tools on the hubs. The sides of the rings of the tools may be provided with indentations to facilitate this flow directly to the tool working face, which in turn provides an improved quality of finish and longer tool life.
A rotary finishing tool comprising an annular ring in which the finishing material is secured and from which said finishing material projects radially outwardly, a drive lug projecting radially inwardly from said annular ring, an adapter hub having an outside diameter only slightly less than the inside diameter of said ring whereby said ring may be closely telescoped over said adapter hub, said adapter hub including a bayonet slot on the circumference thereof adapted to interfit with said lug whereby said ring may be telescoped over said adapter hub with said in lug alignment with said bayonet slot and then rotated with respect to said adapter hub to be properly positioned on said adapter hub and to be driven thereby through the driving engagement between said lug and an end of said slot, said slot being a T-slot with the stem of the T extending axially of the adapter hub and the head of the T extending circumferentially, said lug engaging at either end of the head of the T to provide a drive point between the adapter hub and ring depending on the direction of rotation of the tool, and wherein said adapter hub accommodates two rings side-by-side and has two such head of the T slots circumferentially parallel to each other accommodating the respective lugs of the side-by-side rings.
An eccentric shaft finishing machine comprising a hollow rotatable arbor, adapter hubs mounted on said arbor for rotation therewith and axially spaced therealong, a wheel type finishing tool mounted on each hub, each tool including a ring closely telescoping over the hub, and said ring including at least one inwardly projecting drive lug, and a bayonet slot in the face of the hub whereby said ring may be telescoped over the hub with said rive lug in register with said slot, and then relatively rotated to be mounted on and in driving engagement with said hub, a pair of wheel type finishing tools side-by-side on each hub, each said hub including a hollow interior, radial ports in said arbor communicating with the hollow interior of each arbor, radial ports in each hub between said side-by-side wheel type finishing tools whereby coolant and the like is directed directly at the working face of the tools, and an annular groove in said hub axially between said tools.
