Problems solved by technology

It can realize any six-dimensional force loading in space, and the calibration device and the sensor to be calibrated can be tested once clamped. It has the advantage of compact structure, but when any six-dimensional force is loaded, six electric push cylinders must act together, so More electric push cylinders are required, the layout is difficult, and the synchronization control is complicated
[0005] In summary, the existing six-dimensional force sensor calibration device still has the problems of small calibration loading force range, low calibration force and moment accuracy, many loading force sources required, and complex structure of the calibration loading device.

Abstract

The invention discloses a six-dimensional force sensor calibrating device and a calibrating method thereof. According to the device, a six-dimensional force sensor is loaded between a calibrating loading board and a calibrating platform base; at least one force loading device is utilized for applying a pressure to the calibrating loading board, and calibration of the six-dimensional force sensor can be realized; a pressurizing device is used as a loading force source; a large loading force is realized, and the six-dimensional force sensor calibrating device is suitable for performing loading calibration on the large-load six-dimensional force sensor on one hand; and on the other hand, the pressurizing device can realize continuous linear loading of a six-dimensional force; furthermore thesix-dimensional force sensor calibrating device only requires two force loading devices; and through adjusting the direction of the applied force, single loading calibration of each dimensional forceand the moment component and mixed loading of a six-dimensional force component can be realized, thereby effectively reducing the number of loading force sources and reducing structure complexity. Thesix-dimensional force sensor calibrating device and the calibrating method thereof have advantages of simple structure, convenient detachment and combination, and flexible calibration to the six-dimensional force sensor.
