Abstract
A device for changing tools, pick-ups, welding torches, and other implements that can be handled by industrial robots. It consists of an upper and lower part. In order to obtain optimal cost effectiveness a linear drive mechanism guides a hook-shaped structure in the upper part along a guide in such a way that the structure initially carries out a curved motion essentially perpendicular to the linear closing or opening motion during the closure process. The curved motion is appropriate for making the bottom of the device engage an associated implement even when the latter is stored in an imprecise position. The structure then carries out a strictly linear motion during which the upper part and lower part are exactly aligned by guides integrated into the device and by guide bevels even in the presence of counteracting forces. A motion that can be made as precise as desired can be executed to obtain a closed and mechanically prescribable final position. The aforesaid linear drive mechanism can also be employed for purposes of separation in conjunction with an ejector while the device is opening, even in the presence of counteracting reaction forces.
