Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe production, in particular to an inner diameter measuring device used in steel pipe production. Background Art

[0002] In the production process of steel pipes, accurate measurement of the inner diameter is crucial to ensure the quality and performance of steel pipes. The traditional measurement method is to manually measure the inner diameter of the steel pipe with the help of tools. Although this method can measure the inner diameter of the steel pipe, the measurement efficiency is usually average and the measurement accuracy is poor. In order to improve this phenomenon, a new type of steel pipe inner diameter measuring device is developed, which has become an urgent need in the current steel pipe production field.

[0003] A device for measuring the inner diameter of a rectangular steel pipe with reference announcement number CN209588932U includes: a chassis, four first connecting rods, four second connecting rods, eight rolling bearings, a bracket and two sets of positioning sliders. The device can ensure that the four rolling bearings contact the inner wall of the rectangular steel pipe at the same time by sliding the two sets of positioning sliders downward successively. Only two measurements are required to calculate the two inner diameters of the rectangular steel pipe. Therefore, the device is relatively convenient to use. In addition, the device also has the advantages of low manufacturing cost and high measurement accuracy. According to the above, although the device can be well applied, it is usually not convenient to measure the inner diameter of the steel pipe in multiple stations in sequence, which makes it difficult for the device to achieve the expected measurement efficiency of the steel pipe, which often troubles users.
