A two-dimensional force sensor for a robotic arm

Abstract

The utility model discloses a two -dimensional force sensor for machine arm, including force detection main part, and force detection main part includes two parallel beams, perpendicular department and two flange rings, and the opposite side of the first end of two parallel beams is integrally formed with perpendicular department, and the second end of two parallel beams is integrally formed with the inner ring wall of two flange rings respectively, and the end face of parallel beam is lower than the end face of corresponding flange ring, one parallel beam is provided with first dumbbell groove, and the outside of one parallel beam is provided with first strain gauge relative to the both ends of first dumbbell groove, another parallel beam is provided with second dumbbell groove, and the outside of another parallel beam is provided with second strain gauge relative to the both ends of second dumbbell groove. The utility model discloses a two -dimensional force sensor for machine arm can effectively detect vertical stress and lateral stress, and avoid the interference that flange causes force sensor in the installation process, ensures the accuracy and reliability of measurement.
