机床大件在机床使用中,起着支持、承载和稳定作用,要求结构要合理。本文着重阐述了机床大件焊接结构的造型特点和焊接结构设计时的要求和注意事项,又对机床焊接结构的工艺设计作了介绍。 Large machine tool used in the machine, plays a supporting, bearing and stabilizing effect, requiring a reasonable structure. This article emphatically expounds the modeling features of large-size machine tool welding structure and welding structure design requirements and precautions, but also introduces the process design of welding machine structure.
