【摘要】：在成形磨削几何原理基础上,基于SK7032螺杆转子磨床提出大型螺杆转子分段磨削技术。根据齿轮啮合原理,分析砂轮刀具在分段磨削螺杆转子时的空间包络运动形式,建立转子分段磨削刀位轨迹计算模型。在螺旋面加工中对转子分段磨削中产生的干涉进行分析,并制定干涉消除的具体方案,达到刀位轨迹优化。针对大型螺杆转子分段磨削的功能要求开发了"螺杆转子分段磨削计算软件",参数化输入并得出转子分段磨削数控加工程序;根据生成的加工程序,在SK7032螺杆转子磨床上进行分段磨削试验,验证了大型螺杆转子分段磨削的可行性,为螺杆转子的数控加工提供一种新的方法。
[Abstract]:Based on the geometric principle of forming grinding, a large screw rotor segmented grinding technology is proposed based on SK7032 screw rotor grinder.According to the gear meshing principle, the spatial envelope motion of grinding wheel tool in grinding screw rotor is analyzed, and the calculation model of cutter path of rotor section grinding is established.In helical surface machining, the interference generated in rotor grinding is analyzed, and the specific scheme of interference elimination is worked out to optimize the tool path.According to the functional requirements of segmental grinding of large screw rotors, a "calculation software for segmental grinding of screw rotors" was developed, which was parameterized and the NC machining program for rotor segmental grinding was obtained.The experiment of segmental grinding on SK7032 screw rotor grinder verifies the feasibility of segmental grinding of large screw rotor and provides a new method for NC machining of screw rotor.
