摘　　要：文章分析了常用固定V型块独立限位造成定位误差的原因。在通过探究支承板限位的定位误差以及定位元件不同固定形式的定位误差的基础上,提出了一种新定位方案。通过计算和比较得出,新方案的定位误差小于用V型块独立限位的定位误差。The paper analyzes the reasons of the location error of the V-block positioning.It has proposed a new positioning scheme in the analysis of the bearing plate limit and the different fixed forms of positioning components.It obtains that the positioning errors of the new scheme is less than the independent V-block positioning by calculating and comparing.The project has a practical significance to reduce original errors of the process system and improve the accuracy of work piece.
