Abstract

The invention relates to a bipedal clamping type high bearing precise linear driver, and aims to solve the problems of low driving force, weak load bearing capacity, low output precision and the likeof the existing piezoelectric linear driver. The bipedal clamping type high bearing precise linear driver is composed of a sliding upper plate, a sliding upper plate installation bolt, a packaging cover, a packaging cover fixing bolt, a linear driving stator, a guide rail assembly fixing bolt, a base assembly, a linear driving stator fixing bolt and a guide rail assembly. The large output force ofthe driver is realized by the flexible hinge clamping mechanism, high load bearing is realized through the upper arrangement of the guide rail assembly and the lower arrangement of the linear drivingstator, the elastic beam is arranged on the linear rhombus hinge driving connecting beam, the pre-tightening force of the driver is fine-adjusted by adjusting the loading screw of the guide rail andthe extrusion force of the elastic beam, and the stable output of the performance of the driver is ensured by the driving feet. The v has the advantages of simple structure, high resolution, high loadbearing capacity, stable performance, convenient pre-tightening adjustment and the like and has a wide application prospect in the field of micro-nano processing and manufacturing.

Description

technical field [0001] The invention relates to a double-foot clamping type high-load precision piezoelectric linear driver, which belongs to the technical field of precision micro-nano drive and micro-positioning. Background technique [0002] With the advancement of science and technology and the continuous development of precision manufacturing technology at home and abroad, the demand for micro / nano-level high-precision drives continues to increase.
