摘要
针对光栅刻划机中超精密摩擦驱动机构对压紧力精确可调的要求,设计了一种偏心轮驱动簧片式施压机构,实现输出压力的精确调节,该机构具有结构简单、制造方便、精确调节压力、调节范围大等优点。应用弹簧基本原则设计变截面等应力簧片结构尺寸,并对其使用中的最大应力以及变形量进行分析。压力调节范围为0至5 529 N,压力调节分辨力为0.4 N,实验表明偏心轮驱动簧片式施压机构可以精确的调节输出压力,满足了摩擦驱动机构对压紧力精确可调的使用要求。
Ultra-precision friction drive mechanism on high-precision diffraction grating ruling engine needs enough pressure and precision adjustable. In order to satisfy the requirements it is desirable to use eccentric wheel drive leaf spring pressure mechanism. The mechanism has been chosen for its simple construction, easy manufacturing, precision adjustable pressure and with wide adjustment range. Based on spring principle the variable cross-section with equal stress leaf spring is designed, and the stress and elastic deformation of leaf spring is analyzed. The eccentric wheel drive leaf spring pressure mechanism with 0 - 5529N adjustment range and with 0.4N resolution.
