CUTTING MACHINE REMOVABLE MEMBER SAFE-GUARD Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: safe-guard gas a body, a sleeve with an inner conical self-braking surface connected to a hydraulic cylinder, a link connected to a hydraulic cylinder rod and clamping members with a spherical surface mounted on supports made in the body for engagement with an inclined surface made on the link, and by the spherical surface - with the inner conical self-braking surface of the sleeve. Two flat wedge and two flat surfaces are made on each clamping member, one of the flat wedge surfaces engages with the inclined surface of the link, two flat surfaces are parallel to each other and perpendicular to the wedge surfaces. The supports are made in the form of slots located diametrically opposite to the link axis. Each clamping member is mounted in the slot for engagement of one of the wedge surfaces with the slot bottom, and of parallel flat surfaces - with its walls. The sleeve is connected to the hydraulic cylinder by hooks made in it and engageable with an inner annular groove made in the sleeve. EFFECT: improved structure. 4 dwg
