High-efficiency high-reliability low-cost sealing apparatus for gas tightness detection of motorcycle fuel tank

Among them: the manual cam sealing device uses manpower as the power source, and the cam is moved by the handle. It has a simple structure, low work efficiency, high labor intensity, and the cam is easy to wear; The sealing device that directly or indirectly seals the fuel tank port requires repeated tightening and loosening of the threaded rod, which has low work efficiency and is only used in single-piece and small-batch production; the quick-clamp compression sealing device is a quick-push clamp The sealing device for sealing the fuel tank port, the sealing device needs the relatively fixed position of the fuel tank and the quick push clamp, and the position of the sealing device must be adjusted when replacing the product, so it is only suitable for the air tightness test of a single product; the middle-mounted cylinder presses and seals The device is to install a cylinder above the fuel tank port, and use the pulling force of the cylinder to make the sealing block seal the fuel tank port. This sealing device also needs the position of the fuel tank and the cylinder to be relatively fixed. Because the fuel tank needs to bear the thrust of the cylinder, it is easy to deform the fuel tank port, resulting in Poor flatness

[0003] It can be seen that the commonly used sealing device for motorcycle fuel tank air tightness testing is labor-intensive and low in efficiency, and there is a problem of poor flatness caused by deformation of the fuel tank port. An efficient, reliable and low-cost sealing device is urgently needed device
