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.
Claims17
A precision positioning device comprising:
- (a) a base;
- (b) a pair of plates mounted on said base for relative slidable movement along parallel axes;
- (c) a plurality of relatively movable guides constrained for mutually coacting movement on said plates, a port of predetermined geometrical configuration formed between said guides, said geometrical configuration governed by the relative positions of said plates;
- and
- (d) driver means operatively connected to at least one of said guides for moving each of said guides, the size of said port determined by the relative positions of said guides.
A precision device for centering a workpiece, said device comprising:
- (a) a base;
- (b) a pair of plates mounted on said base for relative slidable movement along parallel axes;
- (c) a plurality of relatively movable guides constrained for coacting movement on said plates along mutually perpendicular axes, a port of predetermined geometrical configuration formed between said guides, said geometrical configuration governed by the relative positions of said plates;
- (d) driver means operatively connected to at least one of said guides for moving each of said guides, the size of said port determined by the relative position of said guides;
- and
- (e) holder means within said port at the center thereof, said holder means configured to hold the workpiece, the center of said port remaining at a fixed point for various geometrical configurations of said port.
A precision positioning device for centering a workpiece, said device comprising:
- (a) a base;
- (b) a pair of plates mounted on said base for relative slidable movement along parallel axes;
- (c) a plurality of relatively movable guides constrained for mutually coacting movement on said plates, each of said guides having a pair of working sides that are in perpendicular relationship, one working side of one of each said guide parallel to and adjacent to one working side of another one of said guides, a port of predetermined geometrical configuration formed between said guides, said geometrical configuration governed by the relative position of said plates;
- (d) driver means operatively connected to at least one of said guides for moving each of said guides, the size of said port determined by the relative position of said guides;
- and
- (e) holder means at the center of said port for holding the workpiece.
