Positioning system for supporting structural components during assembly

摘要

An x-y-z motion jack unit is mounted on a base frame supported by precision made floor inserts at an assembly site. The inserts are precision positioned in the floor and each insert presents a horizontal support surface for the base frame and a vertical threaded bore receiving an anchoring pin provided by an anchoring unit mounted on the base frame. Multiple of the jack units can be integrated into a computerized adjustment system for positioning aircraft structural components during assembly.
