Abstract

The invention discloses a multi-degree-of-freedom precision control platform. The multi-degree-of-freedom precision control platform comprises a precision six-dimensional parallel positioning table (1), a X-directional linear guide rail (2), a Y-directional linear guide rail (3), a Z-directional linear guide rail (4), a six-axis parallel positioning table controller (5), a linear guide rail controller (6), a power supply control box (7) and a master control computer (8). The large-range adjusting movement is performed by adopting the X-directional precision linear guide rail (2), the Y-directional precision linear guide rail (3) and the X-directional precision linear guide rail (4), the positioning precision is superior to 20 microns, the high-precision location adjusting is performed by adopting the precision six-dimensional parallel positioning table (1), and the positioning precision is superior to 100nm. The precision positioning of a work-piece is realized b adopting a micro-macrocombining way.

Description

technical field [0001] The invention relates to the technical field of multi-degree-of-freedom precision control, in particular to a multi-degree-of-freedom precision control platform, which can realize high-precision positioning of position and angle. Background technique [0002] Precision control platforms are widely used in precision testing, assembly and other fields, but usually the dimension of the control platform is relatively single, and it is difficult to take into account the stroke and precision. When the stroke of the positioning platform is large, its positioning accuracy is low, and when the positioning accuracy is high , it is impossible to achieve large-stroke motion, and it is difficult to meet the needs of engineering applications. Contents of the invention [0003] The purpose of the present invention is to provide a multi-degree-of-freedom precision control platform, which solves the problem that the stroke and precision of the conventional control pl...
