Embodiment Construction
[0035] As mentioned in the background technology, in the existing stick-slip drive cross-scale precision positioning platform, the friction force is adjusted up and down, and the friction force adjustment method is affected by the load change. At the same time, the friction preload structure and adjustment method are relatively complicated. The friction adjustment is limited and the accuracy is affected.
[0036] Next, the specific technical solution of the present invention will be introduced in detail.
[0037] Please also see Figure 1 ~ Figure 4 , the stick-slip driving cross-scale precision positioning platform in the present invention includes:
[0038] Abutment 3, the abutment 3 includes a base, a pre-tightening flexible hinge 37, a drive transmission flexible hinge 32, an inertia mass block 36, and has a pre-tightening screw 2, and a piezoelectric ceramic 1, and the piezoelectric ceramic 1 is installed on the base and Between the inertial mass blocks 36, one end is p...
