Abstract

Parts such as bearings are press-fitted into a workpiece by an automatic system which includes a positioning device for positioning a workpiece, and a pressing device for press-fitting a part into the workpiece which is positioned by the positioning device. The positioning device includes a jig base having a stationary reference surface, a support table movable toward and away from the stationary reference surface, and a pusher unit for pushing the support table to create a gap between an end surface of the workpiece and the stationary reference surface when the workpiece is placed on the support table. The pressing device includes a presser unit including a presser rod for holding the part thereon, the presser unit being movable toward and away from the support table, and an actuator for pressing the end surface of the workpiece against the stationary reference surface to position the workpiece before the part is press-fitted into the workpiece by the presser rod.
