摘要
为了揭示用数控机床U钻动力头替换锥柄麻花钻头对Z3080×25型摇臂钻床钻削加工性能和加工质量的影响,运用机械造型软件Pro-E和多体动力学仿真软件ADAMS建立摇臂钻床的柔性模型,对其进行仿真分析,同时进行物理实机改装试验,并对实测结果与仿真结果进行对比验证。研究结果表明,摇臂钻床在将锥柄麻花钻改用U钻数控动力头进行深孔钻削加工时,U钻末端中点处变形量非常大,达不到加工精度要求。
Aiming to reveal the relationships between the drilling processability and kinds/parameters of drills based on Pro-E and ADAMS, the flexible model of Z3080 X 25 radial drilling machine and the virtual simulation were made. We also carried out the refit experiment of physical prototype. Comparing the simulation results with experimental verification, the research results showed that when drilling the deep hole by using NC machine tool-U drill instead of taper shank twist drill, the deformation of midpoint of the end is very large, so the machining accuracy can not be reached.
