| 摘 要： | 中径差作为评价内螺纹质量的重要参数,对内螺纹的加工质量影响很大.为研究切削锥长度和主轴转速对内螺纹中径差的影响,采用高速钢直槽丝锥对45钢进行了干攻丝试验.试验结果表明:切削锥长度和主轴转速对中径差均有影响.在100 r/min的主轴转速下,使用切削锥长度为2.5 mm的丝锥进行切削可获得最佳的中径差,其中径向中径差的...

| Abstract: | The difference in pitch diameters,as an important parameter for evaluating the quality of internal threads,has a great influence on the processing quality of internal threads.To study the influence of chamfer length and spindle speed on the internal thread pitch diameter difference,a dry tapping test was carried out on 45 steel with a high-speed steel straight flute tap.The test results show that the chamfer length and the spindle speed have an effect on the pitch diameter difference.At a spindle speed of 100 r/min,the best pitch diameter difference can be obtained by using a tap with a chamfer length of 2.5 mm,among which minimum radial pitch diameter difference from the first thread to the third one is 25μm,12μm and 10μm,and the minimum axial pitch diameter difference is 9μm. |
