ABSTRACT:
A boring head of a multiple-operation machine tool comprises a housing which accommodates a carriage carrying a mandrel for a cutting tool, and having a slanted surface to interact with a slanted surface of a rod arranged in the housing coaxially with the carriage and kinematically coupled to a drive which moves it in the axial direction. The housing also accommodates a fork arranged coaxially with the former and pressed against the carriage by a spring. At the ends of the fork are two slanted surfaces which are symmetrical with respect to the axis of rotation of the boring head. The fork interacts with the carriage on lines found in a plane extending through the axis of rotation of the boring head. The head further incorporates a rocker whose axle is installed in the housing on the side facing the two slanted surfaces of the carriage. The axle is parallel with the axis of rotation of the boring head. Mounted on the ends of the fork are rollers whose axles are in a plane extending through the line of contact between the rollers and the slanted surface of the carriage. Stops which are provided on the external lateral sides of the fork are in a plane extending through the axis of rotation of the boring head, and are parallel with the axles of the rollers and in contact with the housing.
