锥形量规是用于检查锥形产品的锥度以及锥度塞规和锥形环规组成的一组标准量规。此外，也可以生产带有切口的锥度规，用来确认该产品在后端面的标准止端。

     Taper gauges are used to inspect gauge taper and taper's standard   diameter (the diameter at the large or small end).Generally comprised of   a taper plug gauge and a taper ring gauge,the connected pair forms a standard gauge.However,this gauge can also be manufactured with a  notch in order to identify this product's standard stopping position on the  end face.(see diagram).

     锥度规的使用方法

     How to use taper gauges

     用锥形量规检查锥形产品的时候，一般在检查锥形孔时以锥形塞规的大端侧面为基准线，或者一断面作为基准，在检查锥形轴时，以锥形侧面的小端侧面为基准，根据与产品孔或者轴的端面的偏差量来断定是否合格。锥度是根据接触的状况进行检查的。检查接触状况时，在塞规的表面均匀的涂一层薄薄的蓝色的糊剂（滑润油一类的），放 入锥形孔旋转几下塞规然后拔出。接触的部分已被量规摩落蓝色糊剂或者红铅粉，由此断定接触状况。为了充分进行检查接触状况，需注意以下几点：

For inspecting tapered products by taper gauges.Generally the inspection of the taper hole is done at the base of thandard line of the large end of the taper plug gauge or at the end face of the taper plug gauge.This inspection of the taper shaft is generally done at the small,end of the end face.Pass of fail is detemined by the amount of deviation from the hole of the product or end face of the shaft.In addition,the taper is inspected by contact.To inspect by contact 05taper,apply a light coat of Prussian bule or light cinnabar evenly on the surface of the plug,and insert it in the tapered hole,the turn the plug a little and remove.As good contact of tpere theapplied bule or light cinnabar is removed from the gauge.Furthermore to perform satisfactory inspection of contact,the following precautions should be noted.

1、 仔细清洁量规以及产品，特别是不得粘附切屑等。

        Clean the gauge and product well,removing any accumulated dust.

2、 在量规的表面均匀的涂一层薄薄的蓝色的糊剂（润滑油一类的）或是红铅粉，涂的时候以颜色来判定。凝固后的颜色变化为相当不同的浅颜色为止细心的涂满产品全身，这点非常重要。

        Apply Prussian bule or light cinnabar evenly over the gauge.It is necessary to apply ti throughly before it changes into a lighter color.

3、 将量规放入产品的过程中应防止相互碰擦，请充分注意。

        Be careful to avoid scraping the gauge and product against each other or putting the gauge in only halfway.

4、 通常，使塞规直立状态下保持或者固定，环规则用相同的力向下轻轻推动环规，使其旋转约八分之一，恢复原状。

        Under normal conditions,hold or anchor the plug in an upring position;then tum the ring about 1/8 while pressing down lightly with even force;then replace it.

5、 小心地将量规和产品分开。此时，请不要让产品和量规相互碰撞。此外，量规之间的相互检查，也采用接触检查。

        Separate the gauge and product gently.Becareful not to scrape this time as well.Contact can also be used for between gauge.
