哈哈,这个都搞不懂33????

ygcygx 发表于 2023-6-19 11:01:00

这个是形位公差里面的平行度公差。
真的需要了解这方面知识,建议找本《互换性与技术测量》来看一下吧

林汐771k 发表于 2023-6-19 11:13:43

........你想学的话,不能先看看机械制图   互换性与技术测量   工艺等 这些入门书吗

-YUN- 发表于 2023-6-19 11:21:56

平行度,你要找到A和B的基准在哪,这个面要和AB两个基准面平行,误差不能超过0.2

wxl2007 发表于 2023-6-19 11:30:40

谢谢指教,实在不好意思,让大家见笑了,确实是没学过机械,我是得找本书看看了。
另外还得请教下,它这个平行度是指上面的 A 和下面的 A,上面的 B 和下面的 B,是吗?如果是的话,它这个平行度怎么测量呢?A 和 A 还好一点,上下都水平,再用经纬仪测量一下侧面应该就平行了,可是 B 和 B 怎么测量平行度呢?用精密水平尺吗?还有就是平行度的单位是什么?0.2 代表什么意思?

东北小王子lk 发表于 2023-6-19 11:48:42

我看是直线的平行度,我来个图片,解释就靠各位大佬了

越来越多的非机跑起来搞机,可见这行业入门之低,活该低工资。

吴文星8214 发表于 2023-6-19 13:30:13

一般图纸会标注基准面。你发的图只有一部分没有标注出来,在完整的图纸里找找2个AB基准。标注的平面必须位于距离公差为0.2mm,且平行于基准线的两平面之间。

标了一般没啥用,起码我这个行业没啥用,标注重要的是什么,是测量,也就是说标注的尺寸是可测量的,像我们这个行业要求不高,形位公差一般不标,即使标了,车间也不看,因为没工艺,想咋弄咋弄,不行? 不行修呗,总有行的,而且修是有工时的
