拉铆螺母技术规范.docx

1、拉铆螺母技术规范1应用围本规应用于地铁车辆铝合金车体上铆螺母的选型，规定了地铁铝合金车体常用铆螺母的代号、基本尺寸、材料等。型号及尺寸见附件。2使用条件铆螺母应能在下列环境条件下正常工作：2.1环境温度为-4080；2.2相对湿度为95；2.3相对于车辆的垂向、横向、纵向存在着频率为150Hz的正弦振动，其振动加速度频率f为110 Hz时等于0.1fg，当频率f为1050 Hz时等于1g；因车辆连挂时的冲击，沿机车纵向激起的加速度不大于3g（g为重力加速度）。3安装方式本规所规定之铆螺母按图1所示方式进行安装：图1：铆螺母的安装方式1）将铆螺母放入铆枪；2）将装在铆枪的铆螺母放入需铆接工件已加

2、工好的孔；3）铆接到位；4）铆枪退出。4铆螺母选型条件选择铆螺母时按如下条件进行选择。铆螺母螺纹的公称直径；如：M3M12；铆螺母头型；铆螺母的头型如表1所示。头型平头型（f）圆柱头型（C）沉头型（F）表1：铆螺母头型；铆螺母类型；盲孔或通孔，采用B和O进行标识，铆螺母类型如表2所示；如C.FO、H.fB类型盲孔通孔表2：铆螺母类型；需铆接工件的板厚；需铆接工件的材质；5铆螺母安装孔的加工铆螺母的安装孔按表3进行加工；平头型圆柱头型沉头型表3：铆螺母安装孔的加工；6铆螺母安装要求安装时，铆螺母至少突出工件0.1mm。如图2所示。图2：铆螺母安装安装后收缩量（安装后测量，发现安装有问题的须重新安
