Machinetool vertical pallet holder comprises holding nipple on pallet to arrestably engage holding bore to temporarily anchor pallet against gravity force in vertical.

摘要

A holding nipple (14) on the pallet (19) fits into a holding bore (15) to hold the pallet temporarily in place. The nipple or nipples per pallet lie above the center of gravity of the pallet. The nipple is ring-grooved (21) for engagement by an arrester pin (24) operated manually, electrically, hydraulically or pneumatically. Play between nipple and bore (15) is kept less than or equal to the maximum permitted chuck play when clamping the pallet in place.
