Abstract
A device is disclosed for mounting a plurality of assembly tools such as grippers or the like on the end of a robot arm. The device includes a turret head for supporting a plurality of grippers and a turret head support member which is shiftably mounted relative on the end of the robot arm. The turret head is rotatable about an axis at an acute angle to the axis of the robot arm. Two angularly disposed pusher arms are carried by the turret support member and extend into a chamber in the turret head. A shaft extends from the end of the robot arm into an opening in the turret support member. A weight compensating member and a position sensor are mounted in the turret support member for cooperation with the shaft.
Claims12
A device for mounting an assembly tool to the end of a robot arm, said device comprising:
- a turret head;
- a turret head support member, said turret head support member including a socket for receiving said end of said robot arm;
- means rotatably supporting said turret from said turret head support member for rotation about an axis extending at an acute angle relative to said robot arm;
- a setting motor for rotating said turret head;
- locking means for locking said turret head in any of several positions relative to said turret head support member;
- said turret head further comprising a plurality of openings for receiving a plurality of assembly tools;
- one of said assembly tools being disposed in an operative position coaxial with the axis of said robot arm when said turret head is locked to said turret head support member;
- said turret head having an enlarged central chamber;
- two push rods mounted on said turret support member and extending into said chamber;
- said push rods being disposed on axes angulated with respect to one another and converging adjacent to an assembly tool mounted disposed in said operative position;
- and fluid pressure means for selectively actuating said rods.
A device for mounting an assembly tool to the end of a robot arm, said device comprising:
- a turret head;
- a turret head support member;
- said turret head support member having a socket for receiving said end of said robot arm;
- means rotatably supporting said turret head from said turret head support member for rotation about an axis extending at an acute angle relative to said robot arm;

- locking means for locking said turret head in any of several positions relative to said turret head support member;
- said turret head further comprising the plurality of openings for receiving a plurality of assembly tools;
- one of said assembly tools being disposed in an operative position coaxial with the axis of said robot arm when said turret head is locked to said turret head support member;
- means mounting said turret head support member on said robot arm for longitudinal shifting movement along the axis of said robot arm;
- said turret head support member having a bore formed therein;
- a shaft extending coaxially with said robot arm;
- a portion of said shaft being disposed within said bore;
- sensing means for sensing relative movement of said turret head support member relative to said portion of said shaft disposed within said bore.
