摘要
针对现装置存在的问题,设计了L型旋臂、水平滑轨和垂直滑轨,利用柱面坐标系原理实现了三线摆光电门围绕仪器主轴旋转的三维调整。设计了运动姿态观测扇形度盘,度盘上表面沿径向刻有5条角度刻线,刻线角间隔5°;沿切向刻有5条幅度刻线,刻线间距与光电门线度相同。通过观察遮光杆外端面与扇形度盘上角度刻线和幅度刻线间的竖直相对位置关系,判定三线摆下摆盘运动姿态是否符合实验原理要求。主要解决了光电门与三线摆下摆盘之间的同轴转动问题及下摆盘运动过程中扭摆角度、横摆幅度的检验问题,同时对原装置水平和竖直方位调整机构进行了优化设计。
Aimed at the problems of the existing devices,the L-shaped spiral arm,the horizontal slide rail and the vertical slide rail were designed,the three-dimensional adjustment of the three-wire pendulum photoelectric switch around the main axis of the instrument was realized by using the principle of cylindrical coordinate system.A fan-shaped dial for motion attitude observation was designed.The upper surface of the dial was radically carved with five angular lines and five angular degree intervals.five amplitude lines were carved along tangential direction,kept angular lines distance the same as photoelectric switch dimension.By observing the vertical relative position between the outer end face of the shading rod and the angle and amplitude lines on the sector dial,the motion posture of the three-wire pendulum swing plate was judged to meet the requirement of the experimental principle or not.It mainly solved the problem of coaxial rotation between the photoelectric switch and the three-wire swing plate,and the problem of testing the swing angle and the swing amplitude during the swing plate movement,at the same time,the horizontal and vertical orientation adjustment mechanism of the original devices was optimized.
