Weihai Cast Iron Inspection Square box Cast iron marking square box manufacturer's price
Do you know anything about the cast iron inspection box?]
What is the purpose of cast iron inspection box?
Let's come to Futao Machinery Company to learn about it!
Introduction of cast iron inspection box;
Cast iron inspection box is made of gray cast iron, generally one hundred Mm to five hundred Millimeter square cube with dimensional accuracy of zero point zero one Within mm, the relative planes are parallel to each other, and the adjacent planes are perpendicular to each other. The allowable errors are all within zero point zero one Within mm. There are also many kinds of square boxes. For some workpieces C The U-shaped collet is clamped on the square box, and when the square box is turned over, all mutually perpendicular lines can be drawn at one time. In order to facilitate clamping various workpieces (including shaft workpieces), a clamping device with V Special square box with V-groove. The square box is made of cast iron six Cavity cube of working faces
Purpose of cast iron inspection square box: square box is mainly used for spare parts Inspection and marking of parallelism, perpendicularity, etc. The square box is made of cast iron with six Cavity cube of working faces, one of which has V Groove. The environmental conditions for square box verification are normal temperature and humidity.
Requirements for cast iron inspection square box: each working face of the square box shall be free of rust, scratches, cracks, dents and other defects that may affect the measurement performance other Defects. The non working surface shall be sand cleaned and painted, and the edges shall be chamfered. There shall be a label on the inner wall of the square box, with the specification, size, grade, factory number and manufacturer name.
Precision of cast iron inspection square box: For the scraped and developed square box, besides the flatness, the contact spot shall be verified by the coloring method. The side length is 25mm The number of spots in any square is: one Level two Level not less than twenty-five Point; three Level not less than twenty Point.
Identification of cast iron inspection box:
Verification method of cast iron inspection box Similar to ordinary cast iron square box, for square box with side length of 300mm and below, place 1mm gauge blocks at both ends of the inspected surface of the square box during verification, place the knife edge ruler on the working surface of the gauge block, and then test plug with gauge blocks at each inspected point. The difference between the size of the equivalent block group just inserted and the size of the gauge blocks at both ends is the deviation between the inspected point and the two ends. This verification shall also be carried out on several sections in the longitudinal, transverse and diagonal directions of the working face of the square box. The greater value shall be taken when the mean square error direction of the straight line measured at each position is consistent, and the sum of the greater positive difference and the greater negative difference shall be taken when the error direction is inconsistent, which is the flatness of the plane of the inspected surface
