摘要:
The present invention is directed to an arbor chuck workholding assembly comprising an arbor chuck (2), outer ring (6), clamp ring (8) and backing ring (10). The arbor chuck comprises a plurality of holding angle lugs (18) and ejecting angle lugs (20) located about its periphery. The outer ring (6) comprises a plurality of complementary holding angle ramps (22) and ejecting angle ramps (24) located on its inner diameter surface. A machine spindle (4) is rotated to engage the holding angled lugs (18) with the holding angle ramps (22) such that the arbor chuck will be drawn into position against the spindle. For disengaging, a reverse rotation of the spindle will result in ejecting angle ramps (24) engaging ejecting angle lugs(20) to loosen the arbor chuck from the spindle. Therefore, no tools are required to secure the arbor chuck to the machine spindle.
