A magazine for nuts comprises a pneumatic cylinder, a piston, at least one tube, a plate, a rod. The tube is a pneumatic cylinder having a partition connected to a rod, on which a piston is located. On the pneumatic cylinder by a bore a sleeve is secured with a tapered bore, in which in the gap between the ends of its opening and pneumatic cylinder a washer is located, which is pressed by springs to the opening end. Under the partition a spring-loaded lower piston is located, in which a stud is attached, which passes through the hole of the partition and rod, whose cone interacts with a rod collet. Under the washer in the pneumatic cylinder a ring is located with an elastic tubular ring, in which, as well as to the piston a compressed air is supplied through electropneumatic valves, pressure reducing valves and throttles with control valves. In the case the washer and piston interact with microswitches, which through the switch close the power circuits of electropneumatic valves and electrical signals on feed of nuts into the wrench heads, storing nuts in the magazine and delivery of all nuts from the magazine. |
