PNEUMATIC GRIP Russian patent published in 2003 - IPC

FIELD: automatization of production processes with automatic gripping and feeding parts to working zone of manufacturing equipment. SUBSTANCE: grip includes hollow housing into cavity of which compressed air is fed and which is mounted with possibility of rotation around central axis. There are tangentially arranged openings on lateral surface of housing. Adaptor rigidly joined with housing is mounted in lower portion of housing. Casing is secured to upper portion of housing. Inner surface of casing together with outer cylindrical surface of hollow housing restrict hollow vortex chamber communicated through tangential openings with annular pumping chamber. It provides creation of turbulent air flow in hollow vortex chamber for evacuating zone at vicinity of axis of pneumatic grip. In base of housing of pneumatic grip disc is mounted for providing ejection ducts in order to additionally evacuate central opening of disc corresponding to bearing surface of grip. EFFECT: enhanced reliability of gripping and holding parts due to creation of high vacuum zone corresponding to bearing surface of grip. 3 dwg
