FIELD: mechanics. ^ SUBSTANCE: proposed manipulator incorporates a combined mechanism representing a combination of a transfer and actuator mechanisms, a drive and a pillar. The aforesaid actuator is, in fact, a cam-and-lever multi-link chain, the driving link representing a swinging cam with its working surface interacting with an intermediate link, a push rod. The latter features a kinematic linkage with the output links furnished with part gripping jaws. The cam working profile represents an Archimedes spiral. The said transfer mechanism is in fact a four-hinge one comprising hinged crank, con-rod, rocker and pillar. Note that the cam is rigidly and axially linked up with the rocker. ^ EFFECT: smaller sizes and higher efficiency. ^ 5 cl, 1 dwg |
