【摘要】：对参数化技术的零件精度变型设计方法进行了研究。根据精度信息生成的基础,得到精度信息尺寸标注位置与零件的几何特征信息直接相关。针对不同类型的精度在零件变型过程中尺寸标注位置不合理的现象,提出了基于变型设计的精度尺寸标注位置调整算法。基于精度标注模型,建立了不同类型的精度尺寸标注位置调整算法,并结合零件的几何特征识别与提取,实现算法对精度信息尺寸标注位置的自动调整。以Solid Works为开发平台,以Visual C++6.0为开发语言,结合Access建立的精度数据库,利用Solid Works API函数对Solid Works进行二次开发,开发出了精度变型设计系统。并以齿轮箱输出轴验证了该系统进行尺寸标注位置调整方法的可行性。
[Abstract]:The design method of part precision variant based on parameterized technology is studied in this paper. According to the basis of accuracy information generation, it is obtained that the position of precision information dimensioning is directly related to the geometric feature information of parts. Aiming at the unreasonable dimensioning position of different types of precision in the process of part modification, an algorithm for adjusting the location of precision dimensioning based on variant design is proposed. Based on the precision tagging model, the position adjustment algorithm of different precision dimension labeling is established, and the automatic adjustment of precision information dimensioning position is realized by combining with the recognition and extraction of geometric features of parts. Taking solid works as the development platform, taking Visual C 6.0 as the development language, combining with the precision database established by Access, the solid works API function is used to carry on the secondary development to the solid works, and the precision variant design system is developed. The gearbox output shaft is used to verify the feasibility of the system.
