Problems solved by technology
People's requirements for precision motion platforms are getting higher and higher. Most of the traditional motion platforms are less-free motion platforms in the form of series mechanisms, that is, most of them are simple superposition of several single-axis platforms, with more joint links and motion components. The accumulation of errors is serious, and most of them are difficult to meet the multi-degree-of-freedom and high-precision at the same time

The invention provides a five-freedom-degree coordinated macro-micro dual-decoupling motion platform. The five-freedom-degree coordinated macro-micro dual-decoupling motion platform is high in motionprecision and comprises five single-freedom-degree drive devices, an I shape is defined by the three drive devices, the other two drive devices are symmetrically arranged along the I shape, a rotationpart and a moving part are arranged on the single-freedom-degree drive device defining the I shape, the other two single-freedom-degree drive devices are provided with wedge blocks, each wedge blockis provided with a sliding block capable of sliding up and down relative to the wedge block, each sliding block is provided with a side column sliding relative to the sliding block, and a moving platform is arranged between the two side columns. Through coordinated fit and macro-micro drive switching of the drive devices, the moving platform can achieve macro-micro motion of five freedom degrees.
Description
technical field [0001] Embodiments of the present invention relate to the field of multi-degree-of-freedom high-speed precision motion platforms, especially five-degree-of-freedom high-precision parallel motion platforms, and specifically to a five-degree-of-freedom coordinated macro-micro dual decoupling motion platform. Background technique [0002] Nowadays, with the rapid development of industries such as precision numerical control processing, integrated circuit manufacturing, micro-electromechanical system processing and manufacturing, and bioengineering, the research and development of manufacturing equipment is imminent. For example, in the microelectronics manufacturing industry, its products have been developing in the direction of small, light, and thin in terms of volume, but their functions are increasingly powerful and diversified. The best way to solve the contradiction between these two development directions is to use finer manufacturing equipment to process...
