Abstract:
A press machine for press fit assembly of a torsion bar to a pinion gear of a power steering system includes a controller and a support structure. A first holder supports a pinion gear, and a second holder supports a torsion bar of a spool-valve assembly of a power steering system. The press machine also includes a sensor adapted to determine a position of a torsion bar in the second holder relative to a pinion gear in the first holder. At least one powered actuator is connected to the support structure and the first or second holders. The powered actuator provides controlled translational and rotational motion to press fit a pinion gear to a torsion bar. The controller causes the powered actuator to rotate one of the holders relative to the other of the holders based, at least in part, upon the position of the torsion bar relative to the pinion gear to thereby provide proper alignment of the torsion bar and pinion gear upon completion of the press fit operation.
