摘要:不锈钢框架存在加工多个平面和孔位,由于形位公差要求较严,必须提高组焊后不锈钢框架精度。根据框架的结构和生产中遇到的问题,提出了使用“三维柔性焊接工装”装夹方法,将刚性焊接代替传统的自由焊接,采取出样板图、构建模型等措施,提高框架的组合精度;其次,优化焊接参数,采用对称焊、跳焊等方法焊接,减少焊接变形;第三,调整加工顺序,减少金加工难度;通过采取多种措施,保证了零件的焊接精度和加工精度。
关键词:框架;平面度;柔性焊接

Abstract:There are many planes and holes in the stainless steel frame, due to the stricter geometric tolerance, the precision of the stainless steel frame must be improved after the group welding. According to the structure of frame and the production encountered problems in the framework of the optimization technology process, proposed the use of “three-dimensional flexible welding jigs” for fixture method by rigid welding instead of free welding, measures such as model drawing and model building are taken to improve the assembly precision of the frame. Secondly, the welding parameters are optimized, and the welding deformation is reduced by symmetric welding, skip welding, etc.; thirdly, the adjustment processing is performed, reduce the difficulty of metal processing; through taking a variety of measures to ensure the accuracy of the welding parts and processing accuracy.
Key words:frame;flatness;flexible welding
