    摘要:

    提出了一種基于夾具實(shí)例庫的定位元件方案設(shè)計(jì)方法。首先，根據(jù)定位基準(zhǔn)表面上的定位點(diǎn)數(shù)目，構(gòu)建了定位元件方案的工藝信息匹配度。其次，根據(jù)工件自身的幾何拓?fù)潢P(guān)系，提出了工件的面、線、點(diǎn)3個(gè)層次的幾何信息匹配矩陣，構(gòu)造了工件的適應(yīng)度及其相應(yīng)的權(quán)重。再次，結(jié)合定位元件方案的工藝信息，建立了定位元件方案的決策匹配函數(shù)。最后，利用典型實(shí)例說明定位元件方案自動匹配算法的詳細(xì)應(yīng)用過程。

    Abstract:

    An automatic matching approach of locator scheme was suggested on the basis of fixture cases. Firstly, in light of the number of locating points, the processing information matching index of locating reference was proposed. Secondly, according of the geometrical and topological relation, the geometrical information matching matrix of workpiece was proposed from three levels of point, line and surface. And then, the fitness index of workpiece and corresponding weight were constructed. Thirdly, the decision function of locator scheme was formulated with combination of the processing information matching index. Finally, some typical examples were used to illustrate the proposed automatic matching approach of locator scheme in detail.
