(57) The invention relates to mechanical engineering, in particular to pneumatic gripping heads of manipulators. The purpose of the invention is to enhance the functionality by ensuring that parts are captured beyond the inner surface. In a gripper containing an annular chamber 3 connected to a pressure source of a working medium by a tangential channel 4, the narrowing annular nozzle 8 is brought to the outer lateral surface of the housing. The rotating air flow, having flowed out of the nozzle 8, acts on the part 11 and, holding it on the gripper, causes it to perform rotational and oscillatory movements. This allows the part to be held on the inner surface and to automatically search for the surface mating with it. The stops 9 can be used to adjust the position of the part on the tong. 2 Il.

The invention relates to mechanical engineering, in particular to pneumatic gripping heads of manipulators.

The aim of the invention is to increase the functionality by ensuring the capture of parts beyond the inner surface,

Fig. 1 shows an embodiment of a gripper with a tangential channel formed in the nozzle; in fig. 2 shows an embodiment of a gripper with a tangential channel made. case.

; The pneumatic tong includes a housing 1 and a nozzle 2, between which an annular chamber 3 is formed, connected to a pressure source of a working medium by a tangential channel 4, a housing 1 and a nozzle 2 are interconnected by screws 5 , displayed on the outer side surface of the housing, on which the height-adjustable limiting stops 9 are installed.

An embodiment of the gripper (Fig. 2) is possible, which is made of three parts - the body 1, the nozzle 2, interconnected by a screw 5 with a spacer sleeve 10. The part is position 11.

The grip works as follows.

Hand gripper torus grip down on. the position where part 11 is located. After

In order to do this, a working medium (compressed air) is supplied to the tong under pressure through the tangential channel 4. Compressed air is twisted in the annular chamber 3 and, accelerating in a constricted annular nozzle 8, is emitted into the atmosphere as a rotating annular flow. The flow interacts with the inner surface of the part and holds it on the tong, while the part 11 performs rotational and oscillatory movements. The stops 9 can adjust its position on the tongue. With the hand of the manipulator, the part is transferred to the position of the assembly, where, under the action of a rotating flow, it automatically searches for the surface of another part that mates it. Next, the compressed air supply is stopped, and the part 11 remains at the assembly position.
