A pick-and-place tool releasably retains a part during a pick-and-place operation
by an automated device. The pick-and-place tool includes a front structure having
a first bore disposed therein for receiving a shaft extending from the part. A
plurality of locking mechanisms is disposed within the front structure. The plurality
of locking mechanisms are evenly spaced around the inner surface and are in fluid
communication with a common fluid source. Each locking mechanism in the plurality
of locking mechanisms includes a bearing disposed proximate an aperture in the
inner surface, and a piston in mechanical communication with the bearing. Movement
of the piston in response to a fluid pressure at the common fluid source forces
the bearing to extend through the aperture and retain the shaft within the first
bore. In one aspect, a resilient member is disposed between the front structure
and a tool holder coupled to the automated device. The resilient member absorbs
at least a portion of a force applied to the front structure.
