螺纹塞规校准方法、检测方法2011-4-2 16:44|发布者: 小编H|查看: 1884|评论: 0|来自: 仪器信息网摘要: 可采用三针法进行检测，具体方法也就是根据螺纹量规的P（螺距）、螺纹角（牙型角α）来确定量佳针径，其计算公式是： do= P/=0.57735P（α=60°时）=0.5637P（α=55°时）1.螺纹中径的检测：可采用三针法进行检测，具体方法也就是根据螺纹量规的P（螺距）、螺纹角（牙型角α）来确定量佳针径，其计算公式是：do= P/[2COS(α/2)]=0.57735P（α=60°时）=0.5637P（α=55°时）；利用相应之量具仪器，如测长机、光学计、外径千分尺等（视螺纹的精密要求而定），同三针一同组合起来对螺纹的中径进行测量，其计算简化公式为：螺纹角（牙型角α）为60°的：d2＝M-3d0+0.866P=M-A，其中A=3do-0.866P；螺纹角（牙型角α）为55°的：d2＝M-3.1657d0+0.9605P = M-A，其中A=3.1657d0-0.9605P。

在上式中M表示经量具/仪器及三针组合后测出的数值结果。

2.螺纹半角（α/2）的检测：可将螺纹量具置于万能/大型工具显微镜之两顶尖间，以影象法或干涉法（推荐用干涉法）进行测量。

3.螺距的测量：同2步，将螺纹量具置于万能/大型工具显微镜的两顶尖之间来进行测量。

4.螺纹大径的测量可通过测长机、光学计、外径千分尺、杠杆外径千分尺等仪器、量具来进行测量。

5.螺纹小径的测量可以以万能或大型工具显微镜来进行测量。

螺纹环规的检定、校准：1.螺纹环规的检定校准方法有两种，一种主要是以测长仪、测长机及其配件（如内测钩、测球、校对环等）来进行测量，其测量过程较、计算复杂，效率低，对操作人员的要求也很高等。

为提高螺纹环规的检定、校准效率以及降低其检定、校准的复杂性，故计量检定部门（如省市、国防计量等）往往以螺纹校对塞规对工作用螺纹环规进行检定、校准，大家都知道外螺纹的检测比内螺纹的检测要简单得多，这也是采用校对螺纹塞规的主要原因。
