ABSTRACT:
A multiple-task end effector attachment for the articulated head of a computer controlled robotic machining center capable of imparting multi-axis linear and rotational movements to the end effector which comprises opposingly aligned master and slave related tool heads that carry multiple tool drivers receptive of selectively changeable tooling. The tool heads are interjoined and rigidly supported in opposing alignment on opposite sides of fixture held stationary work pieces by means of an intervening generally U-shaped yoke or frame of selected configuration dedicated to the particular shape of the parts assembly. The master tool head of the end effector is connected directly to and carried by the mobile head of the robot which powers and controls the positioning and operation of both tool heads of the end effector. The tool heads operationally cooperate in slave relationship to clamp the parts therebetween and form and prepare holes through the work pieces at predetermined locations followed by the installation of selected fasteners such as rivets, bolts and the like. This arrangement enables a single robot to operate multiple tool heads on opposite sides of stationary work pieces.
