1、大型工具显微镜基座设计[摘要]随着科学技术的不断发展,极大地推动了不同学科的交叉与渗透,导致了工程领域的技术革命与改造。在机械工程领域,由于微电子技术和计算机技术的迅速发展及其向机械工业的渗透所形成的机电一体化,使机械工业的技术结构、产品机构、功能与构成、生产方式及管理体系发生了巨大变化,一些精密调节仪器也是孕育而生,对于一些微小的距离和角度调节的精密仪器需求量也是越来越广泛的要求,所以本课题进行精密机械结构的设计、微小位移、微小角度等调节机构的设计。由于是显微镜的基座设计,所以在进行角度和位移调节上都采取手动进行精密调节,首先调节手柄与滚珠丝杠连接带动工作台的移动实现微小
2、横向和纵向的位移,手动调节工作台实现小角度的调节,其内部是利用蜗轮蜗杆传动来实现的。滚珠丝杠和蜗轮蜗杆传动是此次研究的基础和重要环节。其次是进行标准元件的选择和一些零部件的强度校核,最终设计出能够实现角度和直线位移的传动机构。[关键词]传动系统,位移调节,角度调节,强度校核ThedesignofthebaseoflargetoolmicroscopeYouyunxian(Grade11,Class04,MajorMeasurementControlTechnologyAndInstrument,schoolofmechanicalengineering,ShaanxiUni
