Изобретение относитс к машиностроению , в частности к робототехнике, и может быть использовано в промышленны роботах дл обслуживани мелкосерийных производств.The invention relates to mechanical engineering, in particular to robotics, and can be used in industrial robots for servicing small-scale production.

Известно приспособление дл подачи металлических листов по одному из штабел в станок с применением )тных рычагов, включакмцее несущие захваты, состо щие из резиновых присосов. . Приспособление снабжено воздушными цш1индрами, пружиннь1ми электрическими контактами и рамой, св занной с кривошшшой шайбой .A device for feeding metal sheets one by one from a stack into a machine with the use of levers, including bearing grippers consisting of rubber suction cups, is known. . The device is equipped with air-cushioned springs, spring-loaded electrical contacts and a frame associated with a crank washer.

Известен инструмент дл отделени материала от пачки, содержаший пластину кольцеобразной формы с отогнутыми на внешнюю сторону кра ми, выполненную заодно с патрубком, внутри которого помешен обтекатель 2.A known tool for separating material from a pack, containing a ring-shaped plate with edges bent to the outside, is integral with a nozzle, inside which is located a fairing 2.

Известен присос дл отделени лист вого материала от стопы, содержащий корпус, в «отором выполнена полость, св занна через входное отверстие сA known suction cup for separating sheet material from the foot, comprising a body, in the "opening, there is a cavity connected through the inlet to

Однако дл такого присоса характерна невысока надежность отделени в стопе верхней листовой заготовки от последующей и невозможность транспортировани заготовок.However, such a sucker is characterized by a low reliability of separation in the foot of the upper sheet blank from the subsequent one and the impossibility of transporting the blanks.

Цель изобретени - повьш1ение надежности отделедш .The purpose of the invention is to increase the reliability of the separated.

Claims

This goal is achieved by the fact that on the outer surface of the case there is a rotating disk with an adjusting hole coaxial with the adjusting hole, which is made in the case and connects the cavity of the case with the atmosphere, and on the contact surface of the case with the workpiece along the perimeter of the case there are elastic pads in the form of fingers such as rubber. The drawing shows a vibrating suction cup. The vibratory suction cup consists of a body 1, a cavity 2, an inlet 3, an ejcodal orifice 4, elastic pads 5, a disc 6, an adjusting orifice 7 and 8. The diameter of the orifice is larger than the diameter of the inlet. Vibrating suction works as follows. Compressed air from the pneumatic circuit is supplied through the opening 3 to the cavity 2, which is made in size and shape such that the jet 9 provides an excess volume between the surface of the cavity of the housing and the outer surface of the jet. When a jet of air 9 is exhausted from the inlet in the direction of the sheet stock. In excess volume 10, an equilibrium is formed, resulting in an increased lifting force, which in combination with the forces resulting from the increase; The velocity of air outflow in the BWB between the frame and the sheet blank in section 11 ensures the capture of the sheet blank. In this case, the blank is pressed against. to elastic slips, than provide with its reliable capture at transportation. The adjusting hole 8 of the vrasing disk is coaxial with the adjusting hole 7 in the housing, which connects the cavity of the fluid with the atmosphere creating pressure fluctuations that vary in shape but varying around the perimeter of the housing; As a result of this, whether the toothed stock also begins to kick, 4TQ makes it easier to separate the top blank from the next. The proposed vibratory suction unit is advantageously different from the existing ones in that it increases the reliability of separating the upper billet from the foot even if there are irregularities and small holes in the billet, which expands its field of application and eliminates the use of magnetic rashers. Vibration suction device for gripping and transporting sheet blanks, comprising a housing, a cavity through an inlet with a high-pressure pneumatic system, and through an outlet with a diameter larger than the inlet aperture with atmosphere, characterized in It has a disk mounted on the housing with a drive for its rotation and an adjusting hole, in which case the housing has lining, located along the perimeter of its working surface, made of el material, and the adjustment hole is coaxial with the adjustment hole of the disk and connects the body cavity with the atmosphere.
