ABSTRACT:
An apparatus for the exact positioning and fastening of several parts, which have an opening, onto a hollow body, whereby, in the initial state, the opening of said parts, which are to be fastened, is larger than the dimensions of the respective fastening positions of the hollow body. Before the fastening process is carried out by hydraulically expanding the hollow body, the parts are positioned at the respective fastening positions of the hollow body by placing the parts into the depressions of a mold, which comprises at least two parts. The hydraulic fluid is introduced into the hollow body via an inlet element, which is attached to the mold. To prevent leakage of the fluid and contamination of the workpiece, there is an expandable elastic container for the hydraulic fluid, disposed at the inlet element, which adjoins to one end of the hollow body. The container is inserted into the hollow body and is held by a support on its free face. The support is arranged in said mold at the end of said hollow body opposing the inlet element (FIG. 1).
