ADAPTIVE GRIP OF MANIPULATOR Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: grip has body 1, pneumatic cylinder 2 and gripping jaws 4 made as hollow flexible bottles. Two holes 12 and 13 are provided on the side surface of pneumatic cylinder 2. Hole 13 is communicated with the spaces of the flexible bottles and hole 12, with atmosphere. Pneumatic cylinder 2 has piston 5 which carries rod 8 with a pusher. Longitudinal cut 15 is made on piston 5. The length of longitudinal cut 15 exceeds or is equal to the distance between the centers of the above-indicated holes. When the grip moves down, and piston 5 moves upwards cut 15 and hole 13 get aligned. Air from the space of pneumatic cylinder 2 passes through pipeline 14 to the flexible bottles which grip part 17. To release the part, cut 15 is aligned with hole 12, and the spaces of the bottles are communicated with the atmosphere. EFFECT: enhanced manipulation process. 1 dwg
