摘要
目的提高和保证螺旋锥齿轮圆角表面质量,提高加工效率。方法改变以往依靠人工打磨的方式对螺旋锥齿轮圆角表面进行加工,提出应用数控五轴加工中心的方法,借助UG软件的CAM功能对螺旋锥齿轮表面进行数控加工自动编程处理,模拟加工功能来检测走刀路径是否正确,并进行表面精度检测及仿真加工无干涉、无碰撞检验,生成的CLS刀位文件经过专用后置处理得到NC程序,最后在VERICUT软件平台上的虚拟五轴加工中心模拟仿真加工螺旋锥齿轮圆角表面。结果通过UG的CAM功能及VERICUT仿真加工,螺旋锥齿轮的齿廓圆角达到(0.3±0.07)mm,表面粗糙度值为0.64μm,整体一致性好,满足设计要求。结论采用传统的五轴联动机床进行螺旋锥齿轮齿廓的倒角、倒圆加工,可获得理想的齿廓圆角尺寸,提高了螺旋锥齿轮表面精度。
The work aims to improve and ensure the quality of fillet surface on spiral bevel gear so as to improve the processing efficiency. Processing of spiral bevel gear fillet surface by manual grinding was changed and method of NC five axis center processing was put forward. CAM function of UG software was used in NC processing and automatic programming of spiral bevel gear surface. Simulated processing function was used to detect whether the tool path is correct, inspect the surface precision and check whether the simulation processing is free from interference and crash. The generated CLS tool location files could simulate the processing of fillet surface on spiral bevel gear in the virtual five axis processing center on the platform of VERICUT software by obtaining NC program obtained through the special post processing, through CAM function of UG and VERICUT simulation processing, the tooth profile fillet of spiral bevel gear reached(0.3±0.07) mm, the surface roughness was 0.64 μm and the overall consistency was good in conformity with the design requirements. Ideal tooth profile fillet size and improvement of spiral bevel gear surface precision can be obtained by adopting traditional five axis machine tool to process chamfer and fillet of spiral bevel gear tooth profile.
