Abstract
An expanding locating pin assembly configured to locate and hold a part includes a housing, a locating pin, an actuating mechanism, and a controller. The housing is configured with a plurality of radial jaw guides and a part rest face. The locating pin has a plurality of jaws connected to and radially movable in the radial jaw guides and extending past the part rest face. The actuating mechanism synchronously moves the jaws to a radial position and applies a holding force to the part. The controller controls the radial position and the holding force of the jaws. The part rest face of the housing and the jaws of the locating pin are configured to receive the part in a located position. The jaws of the locating pin are configured to hold the part in the located position via the holding force and a friction force resulting from the holding force.
