An adapter for use in friction stir welding is configured to be mountable in and rotated by a standard milling machine. In one embodiment, the adapter includes an upper housing, a lower housing, and a mounting element for transmitting rotational movement from the milling machine. At least a portion of the mounting element is mounted in the upper housing. The adapter may also include a tool holder connected to the lower housing and rotated by the mounting element; and a displacement mechanism for providing movement of the tool holder relative to the mounting element. The displacement mechanism may be isolated from the rotational movement of the mounting element and the tool holder. The displacement mechanism of the adapter may also include at least one piston cylinder assembly. In one embodiment, the upper housing and the lower housing form a part of the piston cylinder assembly. In another embodiment, the piston cylinder assembly is a discreet mechanism extending between the upper housing and the lower housing. The adapter may also include at least one linkage connected to and extending between the upper housing and the lower housing.

Adapter for friction stir welding

An apparatus and method for installing a wheel disc into a wheel rim to manufacture a vehicle wheel includes upper and lower disc engaging members, which are clamped against opposite sides of the disc, and upper and lower rim engaging members, which engage upper and lower edges of the rim. The disc is first separated from the rim to assure proper alignment between the disc and rim and then forced into frictional engagement with the rim, while a compressive force is applied axially along the rim to relieve stresses and facilitate installation of the disc into the rim.
