In the prior art, when manually fixing the six-dimensional acceleration sensor by hand, it is labor-intensive and easy to slip, which may damage the six-dimensional acceleration sensor or injure the installer. The basic principle of the six-dimensional acceleration sensor is the piezoelectric effect: when the piezoelectric material is subjected to an external force along a certain direction, a polarization phenomenon occurs inside, and at the same time, charges of opposite signs are generated on its two end faces, and the amount of charge is the same as The magnitude of the external force is proportional; when the direction of the force changes, the polarity of the charge also changes; when the external force is removed, it returns to an uncharged state.

The basic model of the six-dimensional acceleration sensor is based on the 12-6 SPS Stewart parallel mechanism. In order to accurately and sensitively respond to the movement of the object, it is necessary to install a branch chain on the mass block, and detect the charge change of each branch chain through the piezoelectric effect, so that The force on each branch chain is measured, and the diameter of the thinnest part of the designed branch chain is only 1.5mm.
