Description

Position Verification Jig for Flange Clamp Fastening Part The present invention relates to a jig for determining the manufacturing status of a clamp by checking the position of a clamp fastening part, and more specifically, to a clamp fastening part position checking jig for a flange configured to easily determine whether a clamp fastening part formed on a flange is positioned in an accurate location. Flanges are essential components widely used in industrial settings to connect pipes or machine parts, and their function and role are of great importance. In particular, the clamp connection of the flange plays a key role in stably connecting and maintaining the two parts, and must be formed in the precise position. If the position of the clamp fastening part is inaccurate, there is a high probability that the parts will not be properly joined, which can act as a fatal defect during the connection process. These defects go beyond simple assembly errors and directly affect the stability and efficiency of the entire system; in severe cases, they can lead to system failure or performance degradation. Existing flange inspection methods were mostly carried out using visual inspection and simple measuring tools. While this method can be applied relatively easily in the initial stages, it has the disadvantage that the test results are highly likely to vary depending on the inspector's proficiency or the work environment. In particular, in mass production processes, it is difficult to maintain consistency in the inspection process, so there are limitations in consistently guaranteeing the same level of quality. In the case of flanges with complex shapes or those containing multiple clamp connections, this problem becomes more severe, and verifying the precise location becomes more challenging. These limitations occur repeatedly in industrial settings and can not only reduce the efficiency of the inspection process but also have a negative impact on the entire production line.
