SIX DIMENSIONAL FORCE SENSOR CALIBRATION APPARATUS AND CALIBRATION METHOD THEREOF

Document Type and Number:

WIPO Patent Application WO/2020/143116

Kind Code:

A1

Abstract:

Provided in the present invention is a six dimensional force sensor calibration apparatus, the six dimensional force sensor comprising a sensor elastomer, a stress hole being arranged in the centre of the sensor elastomer; the six dimensional force sensor calibration apparatus comprises a frame, a rotating mechanism, a stress apparatus, a first loading apparatus, a second loading apparatus, a third loading apparatus, and a control system. By means of synchronously loading the two ends of the six dimensional force sensor elastomer, the present invention implements accurate measurement of the force/torque input and output in each dimension; by employing the method of fixed sources of force and a moving sensor to be calibrated, only five sources of force are used, and the entire calibration can be completed by moving the rotating platform only once; the rotating platform is electrically rotated and automatically limited, and the loading apparatuses and stress shafts can rotate synchronously, reducing the difficulty of manual operations and avoiding human error, and having good calibration repeatability; using a spring as a forced storage element avoids the instability errors of motor rotation and implements synchronous calibration of loading and unloading processes.
