经验交流！法兰（接盘）螺栓连接孔位置度公差的简易确定方法。

nana1984

<p>由于本人对书本上位置度公差的取法不解，所以在实际需要的情况下，经与多位工程师商讨，制定出一个确定法兰螺纹孔位置度公差的简易方法（也可以是过孔）。希望与大家分享，如有任何意见或建议，欢迎提出！</p><p>由于文中的示意图是我自己用cad画的，我不会贴图，所以就放在了上传的文件中！有兴趣的朋友可以看看！</p><p>并且，带图的文本我也上传了，看那个更加方便，省得又看图又看帖子。但是记得要给我提意见呀！</p><p>欢迎大家多提意见！如果有更好的方法也欢迎提出，让我们相互交流，共同进步！</p><p>&nbsp;</p><p class="MsoNormal" align="center" style="MARGIN: 0cm 0cm 0pt;
