摘要
蜗杆砂轮磨齿作为齿轮加工的主流方法之一,具有加工效率高、加工性能稳定以及产品质量高等优点,适用于批量化、专业化的齿轮加工。而金刚石磨齿滚轮作为蜗杆砂轮主要的修整工具,其制造精度间距决定了齿轮的加工质量。因金刚石磨齿滚轮采用人类已知的最硬材料制成,其齿廓修整难度极大。因修整工具损耗严重,工程上主要采用光学引导和人工干预手段实现加工。该法制造精度低,难以适应当今人类对齿轮加工精度的需求。为此,文章分析了磨齿滚轮齿形修整时的工具损耗行为,提出了一种基于原点偏移的CNC修整方法,并通过工程实践,验证了方法的可行性。
As one of the main methods of gear machining,worm grinding wheel has the advantages of high processing efficiency,stable processing performance and high product quality,which is suitable for mass and specialized gear machining.The diamond grinding wheel is the main dressing tool of worm grinding wheel,and its manufacturing precision spacing determines the machining quality of the gear.Because the diamond grinding roller is made of the hardest material known to man,it is very difficult to trim the tooth profile.Due to the serious loss of dressing tools,optical guidance and manual intervention are mainly used in engineering to achieve machining.This method has low manufacturing accuracy and is difficult to adapt to today’s human needs for gear processing accuracy.For this reason,this paper analyzes the characteristics of tool loss when grinding roller tooth shape trimming,and puts forward a CNC trimming method based on origin offset,and verifies the feasibility of the method through engineering practice.
