划线平台、划线平板的基本用途:

划线平板介绍
  划线平板是用铸铁材料做成的平板,划线平板应采用优质细颗料的灰口铸铁或合金铸铁制造,是检验机械零件平面、平行度、直线度等形位公差的测量基准,也可用于一般零件及精密零件的划线、铆焊研磨工艺加工及测量等。常见加工方法为刮制法,刮制的划线平板工作面能贮存润滑油和容纳微小灰屑在凹坑中,提高了基准体现的可靠性与稳定性。

1、划线平台是高度测量的基准面:将待测物与量表座一同放置于平台上,进行高度比较测量,最后可再将其高度与标准量块相比较。

2、平行度测量的基准面:固定量表座,然后使量表指针接触在待测物表面上方,移动待测物,可检查工件面与铸铁平板面的平行度。
3、角度测量的基准面:利用平台作基准面,配合正弦杆及角度规,可进行角度量测。
4、是精密划线的基准面:可按照工作图的尺寸,进行精密的划线工作。

5、也可以根据用途在划线平台表面刻制刻度线,使划线、测量等工作更为方便。
划线平板的生产标准:
  划线平台按国家GB7947-1999标准制造。
划线平板的外形结构及形状:
  外形结构制成双围子、单围子和箱体式。如果拼接使用,一般选用单围子外形较好;划线平板的形状有正方形,长方形和圆形。 
  划线平台精加工后,采用人工刮研工艺。不同规格的产品具体平面度参数详见划线平台参数表格。
划线平板的材质:
  为高强度铸铁HT150-300,工作面硬度为HB170-350.

Crossed platform, crossed the primary use of plate:
Crossed flat-panel description:
Dash tablet is a tablet made ​​of cast iron materials, crossed tablet should be used Fine granule gray cast iron or alloy cast iron, is the inspection of mechanical parts plane, parallel, form and position tolerances of straightness and other benchmarks, but also can be used for general parts and precision parts crossed riveting processing and measurement of the grinding process. Common processing method for the scraping method, crossed flat face scraping storage of lubricants and to accommodate the tiny gray debris in the pits, the benchmark reflects the reliability and stability.

1, crossed platform height measurement is the point: for the content and will be placed on a scale with which, the height is measured, and finally to the height and standard LiangKuai compared.

2, the parallel degree measurement datum: a fixed scale, and then make scale pointer to be measured in contact surfaces above, the movement for the thing, you can check the workpiece surface and cast iron plate surface parallel degree.

3 and the Angle measurement datum: using the platform for the datum plane, cooperate with sine bar and Angle gauge, Angle measurement.

4, the point is precision crossed: but according to the size of the working drawing, accurate crossed work.

5, can also according to use in a crossed platform scale line seal surface, make a crossed, measurement, etc is more convenient.

Crossed the plate production standards:
Crossed platform manufactured according to the national GB7947-1999 standard.
Crossed the plate shape structure and shape:
Shape structure made ​​of pairs of villages, single curtain and box type. If splicing is generally used in single curtain shape better; crossed flat shape of a square, rectangular and round.
Crossed the platform, finishing, manual scraping process. Products with different specifications flatness parameter form of the parameters detailed in a crossed platform.
Crossed the plate material:
High-strength cast iron HT150-300, face hardness of HB170-350.
