Abstract
An end-of-arm tooling device for a robot or like manipulator is provided which, in a preferred embodiment, includes a differential separating a first torsional input into first and second torsional outputs, and two jaws for interacting with a workpiece powered by a separate one of the first and second torsional outputs, and wherein, upon interaction with the workpiece at a predetermined torque level by one of the jaws, the jaw's motion will be stopped and torque will be continually transferred to the remaining jaw.
Claims1
An end-of-arm tooling device for a robot for interacting with a workpiece comprising:
- power means providing a first torsional input;
- at least one input shaft powered by the power means;
- a cross shaft connected to the input shaft, the cross shaft having rotatably attached thereto first and second bevel planet gears;
- a first bevel output sun gear concentrically fitted over the input shaft meshed with the first and second bevel planet gears;
- a second bevel output sun gear concentrically fitted over the input shaft meshed with the first and second bevel planet gears;
- a first jaw means torsionally associated with the first bevel output sun gear to interact with the workpiece;
- and
- a second jaw means torsionally associated with the second bevel output sun gear to interact with the workpiece.
