摘要
优化的工艺设计保证多线蜗杆轴加工精度和表面粗糙度。针对多线蜗杆数控车削加工时牙槽深、切削力大、易啃车刀、易振动、铁屑难排出等问题。采用强力弹性蜗杆车刀,左右车削法与宏程序编程相结合方式,解决蜗杆车削加工时产生振动和啃刀现象,避免刀尖受热和排屑困难,提高加工效率。利用圆周分线法避免蜗杆齿形误差,保证多线蜗杆的合格率。课题研究为今后大螺距螺纹加工提供参考和依据,具有一定的实际价值。
The optimized process design ensures the machining accuracy and surface roughness of multi-wire worm shaft.Aiming at the problems of deep alveolar,large cutting force,easy to gnaw turning tool,easy vibration and hard to discharge iron chips in CNC turning machining of multi-wire worm etc.By using strong elastic worm turning tool,the combination of left and right turning method and macro programming can solve the problem of vibration and tool gnawing during worm turning,avoid the difficulty of tool tip heating and chip removal,and improve the processing efficiency.The circumferential dividing line method is used to avoid the error of worm tooth profile and ensure the qualified rate of multi-line worm.The research provides a reference and basis for the processing of large pitch thread in the future,and has certain practical value.
