Abstract
A releasable joint between two component flanges is for use in a robot arm. The flanges have a number of teeth on each part that is pressed into contact by clamps, screws or other means. The releasable joint assembly is suitable for establishing a robot joint between a first and second component each having interlocking annular flange with respective contact surfaces, and where these flanges are held in place by a clamp.
Claims20
A releasable joint assembly for a joint, the releasable joint assembly comprising:
- a first component comprising a first annular flange, the first annular flange comprising a first contact surface and a first outer surface, the first outer surface having a first curved recess surface, the first contact surface comprising teeth along a circumference of the first annular flange;
- a second component comprising a second annular flange, the second annular flange comprising a second contact surface and a second outer surface, the second outer surface having a second curved recess surface, the second contact surface comprising cavities along a circumference of the second annular flange, the cavities for receiving the teeth;
- a clamp for holding the first component and second component together, the clamp comprising a V-clamp having a curved bulge surface configured to fit in the first curved recess surface and the second curved recess surface;
- wherein the teeth are at a first angle relative to the first contact surface and the cavities are at a second angle relative to the second contact surface, the first angle and the second angle being substantially same.

A robot system comprising:
- a robotic arm comprising a first component, a second component, and a clamp for holding the first component and the second component together, the clamp comprising a V-clamp, the robotic arm being movable in six degrees of freedom;
- and
- a processor to provide position commands to the robotic arm to control movement of the robotic arm;
- wherein the first component comprises a first annular flange, the first annular flange comprising a first contact surface and a first outer surface, the first outer surface having a first curved recess surface, the first contact surface comprising teeth along a circumference of the first annular flange;
- wherein the second component comprises a second annular flange, the second annular flange comprising a second contact surface and a second outer surface, the second outer surface having a second curved recess surface, the second contact surface comprising cavities along a circumference of the second annular flange, the cavities for receiving the teeth;
- wherein the teeth are at a first angle relative to the first contact surface and the cavities are at a second angle relative to the second contact surface, the first angle and the second angle being substantially same;
- and
- wherein the V-clamp comprises a curved bulge surface configured to fit in the first curved recess surface and the second curved recess surface.
