Image measuring instrument for high-efficiency measurement of round rubber ring

　　 The image measuring instrument measures the round rubber ring with high efficiency, almost without damage. O-ring is a kind of rubber ring with a circular cross-section. Because its cross-section is O-shaped, it is called O-ring. It is a widely used hydraulic and pneumatic transmission system. It is a ring cover composed of one or several parts, which is fixed on a ring or washer of the bearing and contacts another ring or washer or forms a narrow labyrinth gap. Mainly used for mechanical parts to prevent leakage of liquid and gaseous media under static conditions.

　　 Measuring O-shaped sealing ring, because it is made of rubber, if contact measurement is used, it is prone to deformation, which affects the measurement accuracy and effect. O-ring seals are widely used in seals, and the size of the seal ring is the key to ensuring the normal and reliable operation of the hydro-pneumatic system and components. In the past, the commonly used methods for measuring the size of the sealing ring mainly included cone rod, SM flexible ruler, modified dial indicator, slice projection, tool microscope, automatic cross-sectional imager, etc. The cost of measuring with automatic cross-sectional measuring instrument was high, cone rod, SM flexible ruler , Refitting the dial indicator, slice projection, tool microscope and other measurement methods manual intervention, the degree of automation is not high, the results are affected by subjective factors, the slice projection method needs to destroy the product, and the inspection results also have small errors.

　　 The image measuring instrument uses machine vision to measure the geometric dimensions of the workpiece. In this detection method, it achieves the advantages of non-contact, high efficiency and low cost, and almost non-destructive measurement of the measured workpiece. At the same time, the measurement The technology also involves several key technologies such as autofocus, edge detection, tracking, and edge point fitting. It has been recognized by the industry and is widely used.
