Pneumatic separation mechanism

Abstract

The invention relates to a pneumatic separation mechanism (100) comprising: a threaded shaft (1) with a conical head (12); a hollow cylindrical cylinder body (2) comprising the first and second ends; a pneumatic supply head (3) fitted with the first end of the cylinder body (2); a clamping jaw (4) made in one piece and coaxial with the second end of the cylinder body (2); the clamping jaw (4) comprising four clamping jaws (41) to receive and hold the conical head (12) of the threaded shaft (1), in which the inner surface of the clamping jaws (41) respectively has protruding ridges (41a) made protruding in the radial direction; a pneumatic piston (5) arranged in the cylinder body (2) so that its conical push head (52) contacts the protruding ridges (41a) of the clamping jaws (41).In the connected state of the lower stage (300) and upper stage (200) of the flying device, the threaded shaft (1) is fitted with a threaded connection to the upper stage (200), the cylinder body (2) is arranged in the lower stage (300) so that the clamping jaws (41) of the clamping jaw part (4) pass through the through hole (310) on the wall of the lower stage (300) and clamp the conical cap (12). When it is necessary to separate the stage, compressed air is supplied to the cylinder body (2) through the compressed air inlet (3) to push the pneumatic piston (5) forward, the conical push head (52) pushes the protruding ridges (41a) so that the clamping jaws (41) expand in the radial direction to release the conical cap (12), thereby separating the lower stage from the upper stage.
