Abstract

The invention discloses an ultraprecise piezoelectric positioning platform. A first micromotion module, a second micromotion module and a third micromotion module are matched, and are displaced through a plurality of piezoelectric elements, so that the ultraprecise piezoelectric positioning platform can realize multiaxial, non-equivalent circle and nonlinear micromotion adjustment functions, and achieve a high-precision positioning effect. Besides, the first micromotion module, the second micromotion module and the third micromotion module are combined in a reverse cascade combination mode, and the ultraprecise piezoelectric positioning platform is more flattened, so the volume and the height of the ultraprecise piezoelectric positioning platform are effectively reduced. Moreover, by a modularization design, the ultraprecise piezoelectric positioning platform has a few assembled parts, and is convenient to disassemble and easy to maintain.

Description

technical field [0001] The invention relates to a positioning platform, in particular to an ultra-precise piezoelectric positioning platform. Background technique [0002] With reference to China Taiwan Patent Announcement No. 589240, it discloses a non-linear rotary fine-tuning device with nanometer / micron rotary function. The existing non-linear rotary fine-tuning device includes an arc or circular rotary table, at least A set of displacement driving components installed inside the rotary table and an arc-shaped base or pivot that guides or supports the rotary table to generate rotation, so that the corresponding base or pivot produces a slight movement, so that the The circular or arc-shaped rotary table performs non-linear nano / micron level displacement. [0003] With reference to China Taiwan Patent Announcement No. 567122, it discloses a universal rolling fine-tuning device with Nai / micron rotation function. A spherical rotating table and at least six sets of displac...
