Botou Schindler Machine Tool Platform Measuring Tool Co., Ltd. specializes in the production of various measuring tool castings. The company's products are widely used in machinery manufacturing, parts processing, petrochemical industry, oil refining, power generation, shipbuilding, metallurgy, mining, textile and other industries. The company has an independent quality inspection department. From the inspection of raw materials to the appearance, mechanical properties and physical properties of each batch of finished products, full-time quality inspectors regularly inspect them to prevent any unqualified product from leaving the factory. Cast iron square boxes are mainly used to check the parallelism and verticality of parts and to support workpieces when marking. They are generally cubes or rectangular parallelepipeds with the same side length. Square boxes and rectangular tubes of various specifications and equal heights can be made according to user requirements< br/>The square box is mainly used to inspect the parallelism, verticality, etc. of parts and components. The marking box is a hollow cube made of cast iron with specific working surfaces. One of the working surfaces has a groove box for verification The conditions are normal temperature and humidity. Each working surface of the square box should be free of rust, scratches, cracks, dents and other defects that affect the measurement performance. The working surface should be sand-painted, and the edges and chamfers of the inner wall of the square box should be The sign is marked with specifications, dimensions, grade factory number, and manufacturer name
In addition to verifying the flatness of the scraped and developed square box, the coloring method must also be used to verify the contact spot side length. The number of spots in any square is the grade. , the grade is not less than a point, the grade is not less than a point
Box verification method For square boxes with side lengths of and below, during verification, place measuring blocks at both ends of the inspected surface of the square box, and place the knife-edge ruler on The working surface of the gauge block, and then use the gauge block to test the plug at each of the inspected points. The difference between the size of the gauge block group when it is just inserted and the size of the gauge blocks at both ends is the deviation between the two ends of the inspected point. The calibration should also be When the error directions of the straight lines at each position are measured on several sections in the longitudinal, transverse and diagonal directions of the square box working surface, the maximum value is taken. When the error directions are inconsistent, the maximum positive difference and the maximum negative value are taken. The sum of the absolute values of the differences is the flatness of the plane under inspection
What are the types of cast iron square box products?
The inspection square box is mainly used to inspect the parallelism, perpendicularity, etc. of parts and components. Underline. It is a cavity cube made of cast iron with specific working surfaces, and one of the working surfaces has a groove.
The grooved square box is used to inspect and mark the parallelism and perpendicularity of parts, and the universal square box is used to inspect or mark any angle lines of precision workpieces.
The cast iron square box is used to inspect and mark the parallelism and perpendicularity of parts, and the universal square box is used to inspect or mark any angle lines of precision workpieces.
The use of magnetic square boxes is the same as that of ordinary square boxes. The advantage is that the grooves are magnetic and easy to use.
Square cylinder cushion box The square cylinder cushion box is an important auxiliary tool in flat plate measurement. It is used for fitter three-dimensional scribing, measurement and inspection of parallelism, verticality and various position errors of mechanical parts, and parallelism of parts. Verticality and verticality inspection and support the workpiece when marking.
