Problems solved by technology
At present, all these force measuring plates with three-dimensional force sensors installed on the bottom, each force sensor only measures three-dimensional force, but in fact, because the sensor is installed as a fixed installation, three-dimensional torque acts on it, which causes the omission of the detection torque and affects the sensor's performance. 3D force measurement caused interference, affecting the accuracy of measurement data
In addition, the structure of the three-dimensional force sensor used is mostly force-coupled. Although there are a series of decoupling measures, it still has a great impact on the accuracy of the results.

Embodiment Construction
[0015] The technical scheme of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0016] Such as figure 1 and figure 2 As shown, a six-dimensional force sensor of the present invention includes a support washer 1, a cover plate 2, a housing 3, a bottom plate 4, eight preload knobs 5, a first elastic body 6, a second elastic body 7, and eight lengths The same push rod 8, four force-transmitting steel balls 9 and strain gauges with the same volume. Wherein, the first elastic body 6 is used to measure the force in the vertical direction and the moment in the horizontal direction, that is, the force in the Z direction, as well as the moment in the X direction and the moment in the Y direction. The second elastic body 7 is used to measure the force in the horizontal direction and the moment in the vertical direction, that is, the force in the X direction and the force in the Y direction, and the moment in the Z direction. Th...
