FIELD: combination type mechanisms with complex motion of their outlet links. ^ SUBSTANCE: apparatus includes combination type mechanism including transmission mechanism with outlet link; actuating mechanism with outlet links provided with jaws for clamping articles and joined with outlet link of transmission mechanism; and drive unit. Outlet link of transmission mechanism is in the form of driving link of actuating mechanism. One outlet link of actuating mechanism is rigidly secured to outlet link of transmission mechanism and its other link is jointly connected with transmission mechanism. The last is in the form of cam mechanism having pusher arranged in center, performing reciprocation motion and provided with roller for engaging with cam shaped portions. Articulation joint of outlet links includes pin rigidly secured to free end of outlet link of transmission mechanism. Outlet link of actuating mechanism is mounted with possibility of rotation by angle no more than 90°. In rigid joint of outlet link of transmission mechanism and one outlet link of actuating mechanism the last is positioned in such a way that vertical symmetry axis of article clamping jaw mounted on it is arranged normally relative to stroke direction of outlet link of transmission mechanism. ^ EFFECT: simplified design, enhanced operational accuracy and efficiency of apparatus. ^ 13 cl, 2 dwg |
