Ball Lock Compensator for Use with a Robotic Device

摘要

A compensation device configured to be positioned between a robotic arm and a robotic tool. The device may be configured to directly attach to the tool, or may be configured to be positioned away from the tool. The device generally includes a first section that connects to the robotic arm and a second section that connects to the tool. The second section is movable relative to the first section to provide for the tool to be positioned at various orientations. The second section may comply rotationally about a first axis. The second section may be movable in a second plane. In one embodiment, the second plane is perpendicular to the first axis.

主权项

1. A compensation device configured to be interposed between a robot and a robotic tool, the compensation device comprising:
a first section having an interior space with an axis; a second section connected to the first section and including a central opening, the second section extending radially around the interior space; a piston positioned in the interior space and being movable along the axis; ball members positioned within the interior space and the central opening, the ball members being radially movable relative to the axis; the piston being movable within the interior space and along the axis between a first position and a second position, the second position being farther away from a bottom of the interior space than the first position, the piston being in contact with the ball members in the second position to force the ball members radially outward away from the axis and into contact with the second section to secure the position about the axis of the second section relative to the first section.
