Rapid measurement device of flange bolt hole

Abstract

The invention relates to a rapid measurement device of a flange bolt hole. The rapid measurement device of the flange bolt hole is characterized in that the rapid measurement device of the flange bolt hole comprises a circular flat board and a measuring stud, a threaded hole provided with a plurality of concentric circles is formed in the flat board, and the sizes of the threaded hole circles are identical; the measuring stud is a cylinder, threads corresponding to the threaded hole are arranged at one end of the measuring stud, and the other end of the measuring stud is a smooth cylinder. The rapid measurement device of the flange bolt hole has the advantages of being simple in measurement operation, capable of saving labor and time and accurate in measurement.

Description

technical field [0001] The invention relates to a measuring device, in particular to a fast measuring device for flange bolt holes. Background technique [0002] Flanges, also called flange flanges, are parts that connect pipes to each other and are used for connection between pipe ends. Generally, there is a circle of n flange bolt holes with the same axis on the flange, and the flange bolt holes are evenly distributed on the circumference along the diameter of the flange; in order to ensure that all flanges can be connected to each other, it is necessary to ensure that all The positions of the bolt holes must be at a uniform position, that is, the position deviation of each bolt hole should be controlled within a certain range; it is difficult to measure the position accuracy of the commonly used length measuring instruments such as vernier calipers at present, and it is necessary to measure each The hole distance of two pairs of diagonal bolt holes, the hole distance of ...

Generally, there is a circle of n flange bolt holes with the same axis on the flange, and the flange bolt holes are evenly distributed on the circumference along the diameter of the flange; in order to ensure that all flanges can be connected to each other, it is necessary to ensure that all The positions of the bolt holes must be at a uniform position, that is, the position deviation of each bolt hole should be controlled within a certain range; it is difficult to measure the position accuracy of the commonly used length measuring instruments such as vernier calipers at present, and it is necessary to measure each The hole distance of two pairs of diagonal bolt holes, the hole distance of every two adjacent bolt holes, and then calculate the result to judge whether it meets the standard and meet the requirements of use. This measurement method is very cumbersome, labor-intensive and time-consuming. low efficiency
