Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a novel flange for automobile engines. Background Art

[0002] The automobile engine flange is a key component in the automobile engine. It plays an important role in connecting and fixing the various parts of the engine, ensuring the stability and reliability of the engine operation. Its manufacturing process requires exquisiteness and must have characteristics such as high strength, high precision and good corrosion resistance. High-quality engine flanges can effectively reduce vibration and noise and improve the overall performance of the engine. In the field of automobile manufacturing, the quality control of engine flanges is very important. From material selection to processing, standards and specifications must be strictly followed to ensure the safe driving and efficient performance of the car. Its existence provides a solid foundation for the normal operation of automobile engines.

[0003] At present, when flanges are used to connect automobile engine pipelines, in order to improve the sealing performance of the flanges, a rubber gasket is often added between the two flanges to fill the gap at the flange connection. However, during the operation of the automobile engine, the temperature is high, which can easily cause the rubber gasket to be affected by the high temperature and accelerate oxidation, thereby reducing the service life of the rubber gasket. At the same time, when the gasket is placed between the two flanges, due to the small spacing between the flanges and the obstruction of the flanges, it is difficult to accurately observe the position of the gasket when placing the gasket, which can easily cause the gasket to deviate and result in poor flange sealing. In addition, the deviated gasket is also easy to block the inner cavity of the pipeline, which is inconvenient to use. Utility Model Content

[0027] In this embodiment, by inserting the screw 31 into the mounting hole 23, and putting the first gasket 32 ​​and the second gasket 33 onto the surface of the screw 31, the first flange 2 and the second flange 5 are fastened by the nut 34.

[0028] Example 3

[0029] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the flange gasket 4 includes a metal surface layer 41, a positioning hole 42 is opened on the surface of the metal surface layer 41, a positioning column 43 is inserted into the interior of the positioning hole 42, one side of the metal surface layer 41 overlaps with the side of the flange 21 away from the first automobile engine pipeline 1, the other side of the metal surface layer 41 overlaps with the side of the second flange 5 away from the second automobile engine pipeline 6, the surface of one end of the positioning column 43 overlaps with the inner wall of the positioning groove 22, three positioning columns 43 are provided, the interior of the metal surface layer 41 is filled with rubber 44, the material of the metal surface layer 41 is 3J2 alloy, and the rubber 44 is silicone rubber.
