FIELD: mechanical engineering.
SUBSTANCE: invention relates to the machine building, in particular to the shafts on the process equipment automatic installation methods. In compliance with proposed method, mechanized chuck with variable cam motion and front thrust centre is fitted on machine tool spindle. Rear thrust centre is installed in tailstock quill. Shaft with conical surface is arranged on thrust centres so that its vertex of said surface faces front centre. Then, the cams are given variable movements along the axis of the centres in direction of rear thrust centre. After pressing to the shaft of the inclined plane of one of the cams its movement is stopped, and resumed after pressing to the shaft of the inclined plane of the other cam. Then shaft is fixed simultaneously with two cams.
EFFECT: simplification of the method due to the axial movement of the cams when securing the shaft to the conical surface.
