SU1220796A1 - Pneumatic grip - Google Patents

Description

I

The invention relates to automation of technological processes and can be applied, for example, as gripping devices for industrial robots or manipulators used in mechanical engineering, instrument engineering, radio electronics and other fields of technology.

The purpose of the invention is to increase the load capacity when dialing sets of parts of various sizes,

 The drawing shows a pneumatic gripper with a retained set of assembly parts, a slit.

The gripper comprises a housing 1 with a stepped part 2, a rod 3, located coaxially with the housing with a gap 4 between the mating surfaces. Their coaxiality and straightness are provided by the centering cup 5, in the end part of which there are holes 6 (windows) for supplying compressed air to the retained set 7 of assembled parts. The outlet portion of the compressed air supply channel is an annular slot 8 formed by the tapered mating surfaces of the part 2 of the housing 1 and the nozzle 9 mounted on the rod 3.

The rod 3 is made movable along the axis of the glass 5, Mechanism re10

The shaft of the rod 3 and the control of the size of the annular gap are not shown.

Capture works as follows.

The assembly 7 of assembled parts is captured by inserting the rod 3 and part 2 of the housing into their opening and is pressed against the end of the housing 1 by the pressure of a continuous stream of compressed air emanating from the annular slot 8. The retention of the assembly 7 of parts is maintained throughout the entire process of their transfer. - with a robotic manipulator (not shown) into the installation (assembly) zone. The compressed air enters the exit section of the annular slot 8 through the holes 6 of the centering cup 5 and the gap 4 between the mating surfaces of the rod 3 and part 2 of the housing 1. After the set of 7 parts has been transferred by an industrial robot or manipulator to the assembly position, they are installed. The grip begins to approach the overthrust position downward, and the compressed air stops flowing into the grip body. In this case, the retention of the set of parts by the flow of compressed air is stopped and they are installed in the process machine or assembled with the base part (not shown).
