核心提示:随着我国汽车工业的发展,焊接技术在汽车生产中的应用越来越多,生产效率和产品质量要求越来越高,焊接装配夹具及各种机械化、半自动化和自动化的焊接装配生产线也随之发展起来。随着生产的需要,国内较大的汽车厂都有了专门从事焊接装配夹具设计的专业人员, 这门处于机制和焊接专业边缘的专业技术, 正在实践中得到发展。

随着我国汽车工业的发展,焊接技术在汽车生产中的应用越来越多,生产效率和产品质量要求越来越高,焊接装配夹具及各种机械化、半自动化和自动化的焊接装配生产线也随之发展起来。随着生产的需要,国内较大的汽车厂都有了专门从事焊接装配夹具设计的专业人员, 这门处于机制和焊接专业边缘的专业技术, 正在实践中得到发展。

而焊接装配夹具设计技术发展得比较晚,国内外相关的专著也较少见。今天为大家分享一篇文章介绍关于设计焊接夹具中的一些难点。
