[0002] Sealing gasket is a kind of sealing spare part used in places with fluids such as machinery, equipment, and pipelines. It can seal the inside and outside. Sealing gasket is made of metal or non-metallic plate material through cutting, stamping or tailoring. It is used for sealing connections between pipelines and between parts of machinery and equipment.

[0003] In order to adapt to components of different shapes, some gaskets need to be processed with a certain curvature on their edges. However, due to processing equipment and operation reasons, in order to ensure production quality, it is generally necessary to measure the curvature of the gaskets. When inspecting the periphery of the gaskets, the existing measurement methods are mostly visual experience methods and mold comparison methods. The visual experience method is too dependent on manual labor, and therefore, there are large errors. The mold comparison method is not very flexible. Based on this, the present application proposes a gasket curvature measuring instrument to solve the above problems. Utility Model Content
