FIELD: metal cutting machine tools, possibly devices for basing and fastening parts such as discs with diametrically arranged opening.
SUBSTANCE: apparatus for basing and fastening parts includes spindle, stepped tie rod mounted with possibility of axial motion in cylindrical housing secured to spindle. Housing has diametrically arranged groove in which centering member in the form of spring-loaded bracket is arranged outside worked part. Said bracket is mounted on stepped tie rod and it is provided with stem entering coaxial openings on ends of bracket. Axis of said coaxial openings is normal to rotation axis of housing. Stationary clamping disc is mounted on outer side of housing. Movable clamping disc is mounted on tail stock with possibility of axial motion.
EFFECT: simplified design of apparatus, enhanced accuracy of basing and fastening part for further mechanical working.
