A device for positioning a workpiece includes a socket body rotatably held on a metallic ball by an array of permanent magnets arranged into a partial socket. An air delivery system controls a flow of air passing between the magnets and the ball to alter the friction between the socket body and the ball. A positive flow of air into the socket reduces the friction, allowing the workpiece to be more easily rotated during repositioning, whereas drawing air away from the socket produces a partial vacuum which increases the friction, causing the socket body to be locked in a single position on the ball.

Method and device for positioning a workpiece

A production moving line system. An illustrative embodiment of the production moving line system includes at least one metallic guide strip and at least one tow vehicle which may be adapted to follow the guide strip. The tow vehicle may include control circuitry and a power source and a wireless transceiver connected to the control circuitry. An assembly fixture cart may be coupled to the tow vehicle. A wireless communication link may be provided between a central control computer and the wireless transceiver of the tow vehicle. A production moving line method is also disclosed.
