Abstract

The invention provides a multifunctional micro-drive interface module, characterized by comprising active lever, fixing platform and two link rods, where the upper end of each link rod is connected through elastic rotating auxiliary with the bottom end of the active lever, respectively, and the lower end of the link rod is connected through elastic rotating auxiliary with elastic moving auxiliary fixed on the fixing platform, the bottom end of the active lever is connected through elastic rotating auxiliary with the fixing platform, and the rotating axes of all the elastic rotating auxiliaries are parallel to one another. And its advantages: (1) using lever principle, and when selecting different input ends, able to implement micro-displacement or force amplification at the other end; (2) designed according to the motion principle of parallel mechanism, so that in the operating course, only elastic moving auxiliaries and elastic rotating auxiliaries generate micro deformation, having very high motion accuracy. And its structure is simple and compact, and it can be widely applied to large operating space or ultraprecision machining field of heavy loads.

Description

Technical field [0001] The invention belongs to the field of manufacturing technology, and in particular relates to a multifunctional micro-drive interface module capable of increasing output displacement or output force. Background technique [0002] The scale used in the manufacturing field is moving from micron to nanometer. With the continuous improvement of processing and manufacturing precision, on the one hand, it is necessary to complete high-precision micro-operations, and on the other hand, it is necessary to expand the reachable working range of micro-operations. At present, most of the micro-operation platforms with large working spaces are composed of macro-motion and micro-motion in series, so there are problems such as accumulated errors, complex structures, and low motion resolution; the large-stroke nano-resolution loading mechanism developed by Xi'an Jiaotong University (Note: Wang Hairong, Zhao Zexiang, Jiang Zhuangde, Development of a large-stroke nanomet...
