摘要
介绍了应用于履带式起重机吊臂(桁架结构)的拼焊工装,其方法是利用两平行(间距可以相对调节)的墙板,每个墙板上有很多个螺纹孔,利用专用支座和销轴,实现了不同截面桁架结构吊臂的拼焊,拼焊后的臂架结构不需要机械加工,就可以满足图纸要求,可以同时拼焊两个履带吊臂架,既提高了工作效率,又降低了加工成本。
one crawler crane jib （latticed structure） spell welded fixtures. Its characteristic is to use two parallel （spacing can be relative regulation） wallboard, each wallboard has 520 screw hole, using the special bearings and pin shaft, realize the different section of the jib latticed structure spell-welded, the jib structure after the spell welded with on mechanical processing can meet with the requirements of drawings, can also spell-welded two crawler jib frame. Improve the working efficiency and reduce the processing cost
