曲轴校直修复工艺新技术

New technology for crankshaft straightening and repair process

在分析了几种曲轴校直方法的基础上,指出了它们在曲轴校直中存在的问题,同时阐述了人工敲击矫正方法中合理的部分,在充分论证和试验的基础上,依据轴类产品校直的材料力学理论及现代机械结构技术,设计了新型半自动曲轴校直工艺装备并编制了新的工艺规程。经过实践证明,该技术完全符合生产现场的技术要求和生产要求。

On the basis of analyzing several crankshaft straightening methods,the paper points out the problems of those methods in crankshaft straightening,and elaborates the reasonable parts of manual hammering correction methods.On the basis of sufficient demonstration and experimentation,we designed a new semi-automatic crankshaft straightening process equipment and formulated a new process specification based on the material mechanics theory and modern mechanical structure technology of shaft products straightening.Practice has proved that the technology fully meets the technique and production requirements in the production site.
