摘要
侧板在精密磨削中的平面变形,严重影响零件质量。通过对工件结构刚度及精密磨削受力状况分析,设计夹具夹紧力与侧板第一定位基准面平行,既避免了产生平面变形的夹紧应力,又为工件平面法线方向的其他工序应力及时释放提供了条件。设计夹紧元件为下沉工作方式,增强了自身结构刚度;工件在夹具中采用成对夹紧、多组布置,提高了生产效率。结果表明:夹具完全能保证侧板的质量和生产要求。
In precision grinding, plane strain affects the quality of side plate seriously. Based on the analysis of structural stiffness and precision grinding stress, the clamping force was designed to be parallel with the first positioning surface in order to avoid clamping stress causing plane strain and make other stress along normal direction timely released. Working in sink mode, the structural stiffness of workpiece was improved. Pairs of clamp and group layout was used to improve productivity. The result shows that the clamp fully meet the quality and production requirements of side plate.
