A Quick Pinpoint Method for Positioning Subminiature Accessory
-
摘要: 微型零件作为精密机械的重要组成部分,其定位在微小型系统中起着至关重要的作用。提出了一种V型叉-气阻尼的微型零件快速精确定位方法,V型叉实现微型零件的粗定位,阻尼实现微型零件的精确定位。然后采用图像处理的方法对其定位精度进行了分析,经过数据处理可知本方法达到了40μm的定位精度。最后分析了定位误差来源。该方法具有定位速度快,对零件无损伤,方法简洁,成本低的优点。Abstract: Subminiature accessory is an important part of precision machine. The positioning plays an important role in mini-system. A method for positioning subminiature accessory is presented based on the V-fork and air damping. The V-fork can position subminiature accessory roughly,andthe damping can position subminiature ac-cessory precisely.Then the positioning accuracy is analyzed by using the image processing,and a positioning accu-racy is 40 μm after data processing.The present method can position subminiature accessory quickly,avoid dama-ging subminiature accessory and the present method can be implemented easily with low cost.
