平板平台基地铸铁方箱各项简介

　　铸铁方箱检定方法对于边长为300mm及以下的方箱，检定时在方箱被检面的两端各放置1mm的量块，把刀口尺放在量块工作面上，然后在其各被检点处用量块试塞，当量块组刚刚塞入时的尺寸与两端量块尺寸之差为该被检点对两端之间的偏差。这一检定还应在方箱工作面的纵向、横向和对角线方向的几个截面上进行。在测得的各个位置的直线中误差方向一致时取其最大值，当误差方向不一致时取其最大正差与最大负差绝对值之和，为该受检面平面的平面度。
　
　铸铁方箱主要用于零部件平行度、垂直度的检验和划线时支撑工件，一般为边长相同的正方体或长方体，可根据用户要求制作各种规格和等高方箱及长方筒。
　　铸铁方箱：按JB/T3411.56-99标准制造，材料HT200。
　　要求：方箱各工作面不能有锈迹、划痕、裂纹、凹陷以及影响计量性能的其他缺陷。非工作面应清砂涂漆，棱边倒角。在方箱内壁应有标牌，并标有规格尺寸，级别出厂编号、制造厂名称。
　　精度：对于刮研制方箱除检定平面度外，还要用涂色法检定接触斑点。在边长为25mm任意正方形内斑点数为：1级、2级不少于25点；3级不少于20点。

1. 用途：方箱主要用于零部件的平行度、垂直度等的检验和划线。方箱是用铸铁制成的具体6个工作面的空腔正方体，其中一个工作面上有V型槽。方箱检定的环境条件：常温、常湿。 　　
2. 要求：方箱各工作面不能有锈迹、划痕、裂纹、凹陷以及影响计量性能的其他缺陷。非工作面应清砂涂漆，棱边倒角。在方箱内壁应有标牌，并标有规格尺寸，级别出厂编号、制造厂名称。 　　
3. 精度：对于刮研制方箱除检定平面度外，还要用涂色法检定接触斑点。在边长为25mm任意正方形内斑点数为：1级、2级不少于25点；3级不少于20点。 　　
4.铸铁方箱检定方法：对于边长为300mm及以下的方箱，检定时在方箱被检面的两端各放置1mm的量块，把刀口尺放在量块工作面上，然后在其各被检点处用量块试塞，当量块组刚刚塞入时的尺寸与两端量块尺寸之差为该被检点对两端之间的偏差。这一检定还应在方箱工作面的纵向、横向和对角线方向的几个截面上进行。在测得的各个位置的直线中误差方向一致时取其最大值，当误差方向不一致时取其最大正差与最大负差绝对值之和，为该受检面平面的平面度。
Cast iron square box Inspection methods for For side length as the 300mm and the following square box, the test when the in square box by the the the two ends of of the seized surface the various placed the 1mm the amount of block, put knife - edge ruler placed on the amount of block of the work of the surface of, and then in the its were eachbehave at the amount of block test plug, the size of the equivalent block group just stuffed both ends of the amount of the difference between the block size for indecent deviation between the two ends. This test should be carried out in the face of the square box vertical, horizontal and diagonal directions of several cross-section. Whichever is the maximum error in the same direction in the measured position of the straight line, whichever is maximum positive deviation of the maximum negative difference absolute value and when the error direction is inconsistent with the flatness of the surface plane of the subjects.
Cast iron square box for the components parallel and support the workpiece in the vertical degree of inspection and crossed generally the same side length of cube or cuboid, according to user requirements to produce a variety of specifications and high-side boxes and rectangular tube.
Cast iron square box: Press JB/T3411.56-99 standard manufacturing, material HT200.
Purposes: the square box is mainly used for parts of the parallelism, verticality test and crossed. The square box is made ​​of cast iron 6 face of the cavity cube, one surface of a V-groove. The square box test of the environmental conditions: room temperature, and humidity.
Two requirements: each face of the square box can not have rust, scratches, cracks, dents and other defects that affect the measurement of performance. The non-face to the sand, paint, edge chamfering. Signs, due to the inner wall of the square box and marked with the specification size, level serial number, manufacturer name.
Accuracy: For scraping the development of the square box in addition to the test plane aloft, but also with the coloring was used to test contact spots. In the side length of 25mm any square, the number of spots: 1, 2 less than 25 points; 3 not less than 20:00.
4 cast iron square box test: the side length of 300mm and below the square box in square box when the test check both ends of the side of each placed 1mm gauge block, the knife-edge ruler on the amount of block work surface, and then its discreet at the amount of block test plug, the size of the equivalent block group just stuffed at both ends of the amount of size difference between the disorder deviation between the two ends. This test should be carried out in the face of the square box vertical, horizontal and diagonal directions of several cross-section. Whichever is the maximum error in the same direction in the measured position of the straight line, whichever is maximum positive deviation of the maximum negative difference absolute value and when the error direction is inconsistent with the flatness of the surface plane of the subjects.
