在当前的工程设计实验中，激光发射器和各种光学器件的调节定位，都需要一种高精度的定位测量仪器。正是在这种需求下，产生了一系列精密定位测量仪器，本文设计了精密定位测量仪器四维微调工作台。
本设计对四维微调工作台的精密定位原理及结构组成进行了研究。为了实现高精度的快速定位，在系统的机械结构设计上采用粗动台和微动台的组合结构进行控制，达到了满意的定位精度。四维微调工作台是一种高精密定位工作台，通过齿轮、齿条和螺旋的传动，实现X、Y、Z轴方向的调节，同时还可进行水平转角以及垂直仰角的调节。
实现X轴粗调范围：0~25mm 分辨率：0.001mm Y轴调节范围：±25mm分辨率：0.1mm Z轴调节范围：0~22mm 转角粗调范围：0~360° 角度精细调节范围：±5°的主要技术指标。

ABSTRACT
 
This design studies the precision positioning principle and structure composition of 4D Micro motion stage. Which is a highly precision positioning instrument. It can realize three directions’ regulation, including X, Y and Z. by the motor driving of wheel gear, gear rack and threads. And it can also realize level angle and angle of elevation’s driving .It is mainly used in engineering experiment. As the poisoning control stent  it is used to poisoning control of various optical instrument. This devise can be installed on a long guide way to measure a long distance. To realize highly precision poisoning’s fast location, in this design I adopt the way of coarse adjustment trimming combine together. After finish the design I know more about the device’s system constitution and work principle and most important what I designed can satisfy the require precision. Realize the task target requirement that the coarse adjustment coverage of X is 0~25mm, resolution rate is 0.001 mm , the coverage of Y is ±25mm,  resolution rate is 0.1mm, the coverage of Z is 0~22mm , the coarse adjustment coverage of deflection angle is 0~360°, the trimming coverage is±5°
