Abstract:

This invention relates to an apparatus for stabilizing a work piece of ring configuration on a base. The apparatus has a first ring fixed to the base and frictionally positioned within the work piece. A second ring has a portion within the other end of the work piece and a portion covering the other end of the work piece. A plurality of hold downs are connected to a base via hydraulic cylinders and are positioned about the work piece and have arms with rollers attached thereto. In response to actuation of the cylinders, the rollers are automatically swung into position over the second ring and the rollers forcibly urge the second ring and work piece in a direction toward the base.
