VACUUM-TYPE GRIPPING APPARATUS Russian patent published in 2002 - IPC

FIELD: automatization of manufacturing processes, namely automatic gripping and feeding parts to working zone of machines. SUBSTANCE: apparatus includes hollow cylindrical body inside which body sleeve is mounted. Coaxially with it rotating orienting collar and cylindrical bushing are mounted. Annular discharge chamber is formed around outer cylindrical surface of body sleeve. Annular turbulence chamber is formed by inner cylindrical surface of collar and outer cylindrical surface of rotating orienting collar. Annular discharge chamber and annular turbulence chamber are mutually connected by means of tangential passages. Annular duct is formed by inner surface of rotating orienting collar and outer surface of cylindrical bushing. The last forms additional discharge chamber and it is provided with nozzles arranged with inclination angle relative to central axis in order to provide possibility of vacuumizing lower portion of annular duct. Invention provides creation of turbulence flow that allows to receive gripping effort directed in such a way that to match axes of gripping apparatus and part to be gripped. EFFECT: improved design. 2 dwg
