出口澳大利亚的SDA2型机车司机室顶盖结构复杂,其骨架由不同的箱型弯梁组焊而成,外形呈放射状向后延伸,组装难度大。为此提出了一种实用工装设计思路,经实践检验,效果良好。
The roof of SDA2 locomotive cab exported to Australia is complex in structure. Its skeleton is formed by the welding of different box-type curved beams. The shape of the roof is radiating backward and the assembly is very difficult. To this end, a design idea of practical tooling is put forward, which is proved by practice and works well.
