Abstract
A precision positioning device with a pair of relatively movable plates defining a carriage for four relatively movable guides. A centering port having a rectangular profile is formed by the guides which are constrained for mutually coating movement on the plates. The relative positions of the movable plates define the geometric shape of the centering port and the relative locations of the guides determine the size of the centering port. A pedestal configured to carry the article to be centered is positioned at the center of the centering port. A driver momentarily moves the guides and opens the centering port for reception of the article. Bias elements urge the guides against the item for centering the article on the collet.
