Description
技术领域technical field
本发明属于精密与超精密加工技术领域，尤其涉及一种基于楔形进给水平补偿的Z向微位移结构。The invention belongs to the technical field of precision and ultra-precision machining, and in particular relates to a Z-direction micro-displacement structure based on wedge feed level compensation.
背景技术Background technique
近年来随着微电子技术、宇航、生物工程等学科的发展，作为精密机械与精密仪器的关键技术之一的微位移技术也迅速发展起来了。在精密仪器中，无论是大航程的精确定位还是小范围的光学对准，都离不开微位移技术。微位移技术己经成为现代精密仪器工业的共同基础,是衡量一个国家科技水平的重要标志,代表了一个国家加工技术水平的高低，位移技术的水平也反映了一个国家的综合经济和技术水平,是国家制造技术水平的重要标志，是先进制造技术的重要支柱。In recent years, with the development of microelectronics technology, aerospace, bioengineering and other disciplines, micro-displacement technology, one of the key technologies of precision machinery and precision instruments, has also developed rapidly. In precision instruments, micro-displacement technology is inseparable from precise positioning over a long range or optical alignment within a small range. Micro-displacement technology has become the common basis of modern precision instrument industry. It is an important symbol to measure a country's scientific and technological level. It represents the level of a country's processing technology. The level of displacement technology also reflects a country's comprehensive economic and technological level. It is an important symbol of the national manufacturing technology level and an important pillar of advanced manufacturing technology.
尽管微量进给机构技术已经取得很大发展，但要真正开发出高精度、大行程、性能优良的微量进给机构却并非易事，还存在许多亟待解决的问题。在微量进给机构中，大行程与高精度这一对矛盾仍然存在，目前开发的微量进给机构往往只能满足其一，而不能满足其二。如压电陶瓷微量进给机构虽然定位精度很高（小于0.01μm），但其工作行程太小，而机械传动微量进给机构可以达到很大的工作行程，但其定位精度不高。现有的微位移机构存在负载低、Z向（高度方向）进给量少，复合度小，精度不高的弊端。到目前为止尚未解决成熟的方法及产品问世。Although the micro-feeding mechanism technology has made great progress, it is not easy to develop a micro-feeding mechanism with high precision, large stroke and excellent performance, and there are still many problems to be solved urgently. In the micro-feeding mechanism, the contradiction between large stroke and high precision still exists, and the micro-feeding mechanism developed at present can only satisfy one of them, but not the other. For example, although the piezoelectric ceramic micro-feed mechanism has high positioning accuracy (less than 0.01 μm), its working stroke is too small, while the mechanical transmission micro-feed mechanism can achieve a large working stroke, but its positioning accuracy is not high. The existing micro-displacement mechanism has the disadvantages of low load, small Z-direction (height direction) feed, small compound degree, and low precision. So far, mature methods and products have not yet been solved.
