Description

Technical Field

[0001] The invention relates to the technical field of measuring special-shaped shaft pipe fittings, and in particular discloses a telescopic measuring device for special-shaped shaft pipe fittings. Background Art

[0002] Special-shaped shaft pipe fittings refer to pipe fittings with irregular shapes obtained through special processing methods under certain conditions. Special-shaped shaft pipe fittings are mainly used for connection, diversion, filtration and regulation of pipeline systems. At present, special-shaped shaft pipe fittings are mainly divided into two structural forms: special-shaped outer wall and special-shaped inner cavity. Special-shaped shaft pipe fittings with special-shaped outer walls can facilitate the installation of sealing components such as flanges, thereby improving the sealing degree of the pipe fittings; special-shaped shaft pipe fittings with special-shaped inner cavities mainly set their inner cavities to various diameters, and most of them are arranged in a rounded step shape, which is used to reduce or increase the flow rate of the fluid in the pipe fittings, thereby ensuring the stability of the overall system during operation.

[0003] Special-shaped shaft pipe fittings require random inspections by quality inspectors during the production process. During the random inspection process, quality inspectors generally need to use an internal micrometer to measure the inner diameter of the special-shaped shaft pipe fittings. Since the inner diameter of the special-shaped shaft pipe fittings is of various sizes, quality inspectors need to perform multiple measurements, resulting in generally low efficiency of random inspections. In addition, if the inner cavity of the special-shaped shaft pipe fittings is a structure in which the inner diameter of the pipe fitting port gradually decreases, quality inspectors need to extend the measuring claws of the internal micrometer into the innermost part of the special-shaped shaft pipe fittings and make the two measuring claws close to the inner wall of the special-shaped shaft pipe fittings for measurement. During the above operation, since the measuring claws of the internal micrometer are a right-angle structure, and the stepped edge of the special-shaped shaft pipe fittings is a rounded structure, there is an error, which makes it impossible for quality inspectors to accurately measure the inner diameter of the special-shaped shaft pipe fittings, resulting in low accuracy of quality inspection data.
