[0034] Specific implementation mode one: combine Figure 1~Figure 11 Describe this embodiment. This embodiment provides a specific implementation of an orthogonal dual-drive precision piezoelectric stick-slip linear motor. The specific implementation of the orthogonal dual-drive precision piezoelectric stick-slip linear motor is described as follows:
[0035] The oblique trapezoidal orthogonal dual-drive piezoelectric stick-slip linear motor consists of an oblique trapezoidal orthogonal drive assembly 1, a mover assembly 2, a base 3, a displacement regulator 4, a dovetail platform 5 and a dovetail platform limit bar 6 .
[0036] The inclined trapezoidal orthogonal drive assembly 1 includes a gasket 1-1, a fixing bolt 1-2, a pre-tightening screw 1-3, a diamond-shaped vertical hinge 1-4 and a piezoelectric stack 1-5. The gasket 1-1 and the pre-tightening screw 1-3 fix the piezoelectric stack 1-5 in the diamond-shaped vertical hinge 1-4. The piezoelectric stacks 1-5 can be pro...

This embodiment proposes a specific implementation of an orthogonal dual-drive precision piezoelectric stick-slip linear motor drive method. The expression of the orthogonal dual-drive precision piezoelectric stick-slip linear motor drive method is as follows:
[0043] The driving method of the orthogonal double-drive precision piezoelectric stick-slip linear motor can be divided into output enhancement type and motion emergency stop type, mainly because the orthogonal double-drive precision piezoelectric stick-slip linear motor adopts an inclined trapezoidal motion conversion beam 1 -4-8 structure, so that the oblique trapezoidal orthogonal drive assembly 1 is unevenly distributed along the axial direction to generate lateral displacement, adjust the normal contact pressure between the oblique trapezoidal orthogonal drive assembly 1 and the mover assembly 2, and then adjust the obliqu...

This embodiment proposes a specific implementation of an orthogonal double-drive precision piezoelectric stick-slip linear motor driving method in which an oblique trapezoidal orthogonal drive assembly 1 is installed back to back. The driving method of the orthogonal dual-drive precision piezoelectric stick-slip linear motor with back-to-back installation of the cross-drive components is expressed as follows:
[0068] The driving method of the orthogonal double-drive precision piezoelectric stick-slip linear motor installed back to back can be divided into output enhancement type and motion emergency stop type, mainly because the oblique trapezoidal orthogonal drive assembly is installed back to back Orthogonal double-drive precision piezoelectric stick-slip linear motor adopts a 1-4-8 structure of oblique trapezoidal motion conversion beam, which makes the oblique trapez...
