【摘要】：目的:为使零件在设计阶段实现公差的自动分配,研究线轮廓度在计算机中的表达模型。创新点:1.提出一种新的构建线轮廓度公差T-Map图的方法;2.用运动学等效的方法表示理想轮廓公差域的允许偏差。方法:1.将零件轮廓分解成多段,然后分别为每段生成一个实体模型T-Map(图6和7);2.利用布尔交运算将所有分段T-Map合成一个完整线轮廓度的T-Map(图8);3.以弧形短槽为例,演示创建线轮廓度的方法步骤。结论:将弧形短槽轮廓分成多段,先实现每一段的T-Map,再利用布尔交实现整体线轮廓度公差的T-Map图,证明该方法在构建任意轮廓的线轮廓度公差上的有效性。
[Abstract]:Aim: in order to realize the automatic distribution of tolerances in the design stage, the representation model of line contours in computer is studied. The innovation point is 1: 1. A new method of constructing line contour tolerance T-Map diagram is presented. The admissible deviation of the tolerance domain of ideal contour is expressed by the method of kinematics equivalence. Method 1: 1. The contours of the parts are decomposed into multiple segments, and then a physical model T-Mapper is generated for each segment (figure 6 and 7 / 2). All segments of T-Map are synthesized into a complete line contour T-Mapby Boolean intersection operation (fig. 8 / 3). Take the arc-shaped short slot as an example to demonstrate the method and steps of creating line contour. Conclusion: the arc-shaped short groove profile is divided into several sections, each section of T-MapP is realized first, and then the T-Map diagram of the overall contour tolerance is realized by Boolean intersection, which proves the validity of this method in constructing the contour tolerance of arbitrary contour.
