Description

Technical Field

[0002] The purpose of flange shape and position tolerance detection is to ensure the accuracy and stability of flange connection, so as to ensure the safety and reliability of pipeline system. Displacement sensor is often used to detect the shape and position of rotating flange. Flange shape and position tolerance detection is of great significance to the safe, stable and reliable operation of pipeline system, which helps to reduce risks, save costs and ensure engineering quality and compliance.

[0003] When using traditional flange form and position tolerance detection equipment, a three-jaw chuck is used to clamp the flange. However, when the three-jaw chuck is used to clamp the flange, a single chuck needs to be adjusted, which makes flange clamping time-consuming. In addition, the displacement sensor used to detect the flange form and position tolerance is difficult to adjust in height and angle, which is not convenient for detecting different positions of the flange, resulting in low efficiency of flange form and position tolerance detection.
