利用SolidWorks建立专用夹具元件库和辅助定位误差计算

Establishment of Special Fixture Parts Library and Computation of Location Error by SolidWorks

为了提高专用夹具设计效率和定位精度,使SolidWorks更加本地化、用户化,介绍了利用VB开发SolidWorks的形式及开发原理,建立专用夹具标准元件库,利用SolidWorks的设计库建立非标准件的特征库。并结合实例研究了元件库的建立过程。在分析通常定位误差的基础上,提出运用SolidWorks装配体尺寸测量工具辅助定位误差计算的方法。与传统设计方法相比,采用该方法设计有助于缩短专用夹具设计周期,保证定位误差计算精度,提高设计的自动化水平。

In order to improve the efficiency of special fixture design and positioning accuracy, standard parts library and nonstandard components feature library were established with SolidWorks Second Development Technology, some examples were given to explain how to build up library of special fixture parts. A method of location error calculation aided by SolidWorks assembly-size measuring tool was put forward based on common error analysis. This method can shorten the design cycle, ensure the accuracy of location error calculation, raise the level of automation in special fixture design.
