Title:
NOVEL SIX-DIMENSIONAL FORCE AND TORQUE SENSOR
Document Type and Number:
WIPO Patent Application WO/2017/215334
Kind Code:
A1
Abstract:
A six-dimensional force and torque sensor comprises a central boss (2), a cylindrical housing (1) disposed outside of the central boss (2), twelve elastic beams for connecting the central boss (2) and the cylindrical housing (1), wherein the twelve elastic beams are provided with strain gauges (4) thereon respectively as required, and a mounting hole is provided at the bottom of the central boss (2) for mounting a signal processing module (5). The present invention is characterized by structural self-decoupling, high stiffness, high natural frequency, and desirable linearity, repeatability and hysteresis, and thus can measure a greater torque. In addition, the sensor can be designed to have different measuring ranges and sensitivities by varying the dimensions of each of the elastic beams.
