Embodiment 2

[0060] The structure and method steps of this embodiment are the same as those in embodiment 1. The macro drive system of each axis is electro-hydraulic servo drive. Compared with electrical and pneumatic drive modes, the hydraulic servo drive mechanism has greater rigidity, compact structure, and small size. Light weight, good acceleration, etc. The micro-drive system of each axis is driven by piezoelectric ceramics. The electroceramics are small in size, high in resolution and easy to control. Compared with the series mechanism, the parallel mechanism has high structural rigidity and load bearing. The characteristics of strong ability, high precision, compact structure, etc. have been more and more widely used. The invention combines the unique advantages of hydraulic servo technology and piezoelectric technology and is applied to parallel mechanisms. It can realize large stroke and high-precision control. The macro-micro hybrid drive parallel mechanism, control system, and se...
