米索前列醇片塞在什么位置

你好，米索前列醇片一般是塞在阴道后穹窿处的，也就是阴道深部，需遵医嘱用药，以免出现不良反应，流产后一周需做B超复查排除子宫收缩不良或残留的可能。

设计机床夹具的时候对刀块应该给多大？还是随便给？有何标准

在夹具底坐上。刀具的位置可以用塞片在对刀块与刀间进行对刀。塞片一般厚度为m=1.3及5厘米。后者尺寸应用得多。它的厚度的公差采用2级精确度来配合。对刀块用在车、铣及刨等加工工作上。刀具位置以对刀块定位时,其加工精度可到3级。刀具位置以对刀块进行检验,对刀块就像一个基准面一样，从此处给出刀具到被加工工件安装位置的尺寸。

高度对刀块、直角对刀块、侧装对刀块、圆形对刀块。

高度对刀块

1.加工要求:光洁度为8的表面,允许在装配后磨,锐棱倒钝。

2.材枓及热处理:20钢,渗碳0.8~1.0mm,二孔中φ5D两端去碳层,滓火HRC60~64。

3.表面处理:除磨加工表面外,发黑。 [2]

直角对刀块

1.加工要求:光洁度为8的表面,允许在装配后磨,锐棱倒钝。

2.材枓及热处理:20钢,渗碳0.8~1.2mm,二孔中φ5D两端去碳层,滓火HRC58~64。

3.表面处理:除磨加工表面外,发黑。 [2]

侧装对刀块

1.材料:20按GBT699-199的规定。

2.热处理:碳深度0.8~1.2mm,58~64HRC

3.其他技术条件按JB/T804-1999的规定。 [2]

圆形对刀块

1.材料20按GB699-65《优质碳素结构钢钢号和一般技术条件》.

2.热处理碳深度0.8~1.2mm,RC58~64.

3.其他技术条件按GB2259-80《机床夹具零件及部件技术条件》.
