VACUUM GRIPPING DEVICE Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: vacuum gripping device has actuating cylinder 2 made up as one-sided air-operated cylinder. The above- piston space of the air-operated cylinder can be connected with a source of positive pressure and suction cap 5. The rod is coupled with the rod of an additional one-sided air-operated cylinder the housing of which is connected with mechanical hand 15. The above-piston working space can be connected with a source of positive pressure and the atmosphere. The suction cap is provided with central and periphery working spaces. The central working space of the suction cap is connected with a source of positive pressure through the above-piston working space of the air-operated cylinder. The periphery working space is connected with a source of rarefaction. The suction cap is spring-loaded in the direction of the mechanical hand. EFFECT: enhanced reliability. 3 dwg
