螺纹量规尺寸标准对照表【免下载】

以下为螺纹量规尺寸标准对照表，跟着小编一起来看一下吧！扩展资料：螺纹量规定义：螺纹量规是测量内螺纹尺寸的正确性的工具。

螺纹量规有环规和塞规，环规检测外螺纹尺寸，塞规检测内螺纹尺寸。

不论是环规或是塞规都有检测最大极限尺寸和最小极限尺寸的检验量具构成。

螺纹塞规用于综合检验内螺纹，螺纹环规用于综合检验外螺纹。

螺纹量规是测量内螺纹尺寸的正确性的工具。

螺纹量规的种类繁多，从形状上可分为普通粗牙、细牙和管子螺纹三种。

螺距为0.35毫米或更小的，2级精度及高于2级精度的和螺距为0.8毫米或更小的3级精度的塞规都没有止端测头。

100毫米以下的为锥柄螺纹量规。

100毫米以上的为双柄螺纹量规。

螺纹规使用说明：1、通规使用前：应经相关检验计量机构检验计量合格后，方可投入生产现场使用。

使用时：应注意被测螺纹公差等级及偏差代号与环规标识的公差等级、偏差代号相同（如M24*1.5-6h与M24*1.5-5g两种环规外形相同,其螺纹公差带不相同,错用后将产生批量不合格品)。

2、止规使用时：应注意被测螺纹公差等级及偏差代号与环规标识公差等级、偏差代号相同检验测量过程：首先要清理干净被测螺纹油污及杂质，然后在环规与被测螺纹对正后，用大母指与食指转动环规，旋入螺纹长度在2个螺距之内为合格，否则判为不合格品。

3、维护与保养量具（环规）使用完毕后，应及时清理干净测量部位附着物，存放在规定的量具盒内。

生产现场在用量具应摆放在工艺定置位置，轻拿轻放，以防止磕碰而损坏测量表面。

严禁将量具作为切削工具强制旋入螺纹，避免造成早期磨损。

可调节螺纹环规严禁非计量工作人员随意调整，确保量具的准确性。

环规长时间不用，应交计量管理部门妥善保管。

4、注意事项在用量具应在每个工作日用校对塞规计量一次。

经校对塞规计量超差或者达到计量器具周检期的环规，由计量管理人员收回作相应的处理措施。

可调节螺纹环规经调整后，测量部位会产生失圆，此现象由计量修复人员经螺纹磨削加工后再次计量鉴定，各尺寸合格后方可投入使用。

螺纹牙规使用对照表

螺纹牙规使用对照表
序号螺纹标注直径（mm）牙距（mm）牙型角（°）备注
备注：
1.公制螺纹标注中的“M”表示公制螺纹，数字为螺纹的公称直径，数字后面的“×”表
示牙距。

2.美制螺纹标注中的数字为螺纹的英寸表示，后面的“-”和数字表示每英寸的牙数，
如“3/4-10UNC”表示3/4英寸的螺纹，每英寸有10个牙。

3.英制螺纹标注中的数字为螺纹的英寸表示，后面的“-”和数字表示每英寸的牙数，
如“PT3/4-14”表示3/4英寸的锥管螺纹，每英寸有14个牙。

4.牙型角为螺纹的牙形夹角，常见的公制螺纹牙型角为60°，英制锥管螺纹牙型角为

公制螺纹标准

普通螺纹标准规格表螺纹基本知识一、螺纹的名词术语螺纹：在圆柱或圆锥表面上，沿着螺旋线所形成的具有规定牙型的连续凸起。

圆柱螺纹/圆锥螺纹；外螺纹/内螺纹；右旋螺纹/左旋螺纹。

右旋螺纹：顺时针旋转时选入的螺纹。

左旋螺纹：逆时针旋转时选入的螺纹。

完整螺纹：牙顶和牙底具有完整形状的螺纹。

不完整螺纹：牙底完整而牙顶不完整的螺纹。

螺尾：向光滑表面过渡的牙底不完整的螺纹。

有效螺纹：由完整螺纹和不完整螺纹组成的螺纹，不包括螺尾。

公称直径：代表螺纹尺寸的直径。

大径：外螺纹的顶径、内螺纹的底径。

小径：外螺纹的底径、内螺纹的顶径。

中径：一个假想圆柱或圆锥的直径，该圆柱或圆锥的母线通过牙型上沟槽和凸起宽度相等的地方。

单一中径：牙型上沟槽宽度等于1/2基本螺距的地方。

作用中径：在规定的旋合长度内，恰好包容实际螺纹的一个假想螺纹的中径，这个假想螺纹具有理想的螺距、螺纹半角、及牙型高度，并在牙顶和牙底留有间隙，不与实际螺纹大、小径发生干涉。

牙型角：在螺纹牙型上，两相邻牙侧间的夹角。

螺距：相邻两牙在中径线上对应两点间的轴向距离。

螺纹精度：由螺纹公差带和旋合长度共同组成的衡量螺纹质量的综合指标。

二、.螺纹概述一般将螺纹分为圆柱螺纹和圆锥螺纹。

（一）圆柱螺纹1. 普通螺纹（又称米制或公制螺纹）螺纹代号M，牙形角60°，基本牙形为平顶。

精度等级：内螺纹4~8级，外螺纹3~9级。

2. 美标统一螺纹（又称60°英制螺纹）螺纹代号UNC、UNF、UNEF、UN、UNS，牙形角60°，基本牙形为平顶。

精度等级：内螺纹1B~3B，外螺纹1A~3A。

3. 非螺纹密封的管螺纹（又称圆柱管螺纹）螺纹代号G，牙形角55°，基本牙形为圆顶圆底。

精度等级：内螺纹标准级和D级，外螺纹A、B级。

4. 梯形螺纹螺纹代号Tr，牙形角30°（美标为29°），基本牙形为平顶平底。

精度等级： 7~9级，（美标为2G~6G）。
