Device for detecting sealing performance of airbag tank

Abstract

The invention relates to a device for detecting the sealing performance of an airbag tank, which is composed of a compression bolt (1), a rotating nut (2), a fixed frame (3), a compression block (4), an airbag tank (5), a compression rubber gasket (6), a fixed base (7) and an air inflation rod (8), wherein the upper surface and the lower surface of the fixed frame (3) are provided with through holes which are coaxial with each other; the bottom part of the fixed frame (3) is provided with the fixed base (7), the fixed base (7) is provided with the compression rubber gasket (6) thereon, and the airbag tank (5) is arranged on the compression rubber gasket (6). The device is characterized in that the upper part of the airbag tank (5) is provided with the compression block (4), the airbag tank (5) is internally provided with the air inflation rod (8), and the air gets into an inner cavity of the airbag tank (5) through the air inflation rod (8). The device provided by the invention can carry out general detection on bayonets with the sizes being 102.5, 132.5, 152.5 and 199.7 and carry out synchronous detection on a circumferential welding seam and a welding seam at a screw thread, thereby reducing the labor intensity of workers, improving the production efficiency and improving the product quality.

Description

technical field [0001] The invention relates to the technical field of passenger car airbag tanks, in particular to a device for detecting the tightness of an airbag tank. Background technique [0002] One of the important criteria for buses and coaches is the use of air suspension. The air suspension includes structures such as airbags and shock absorbers. In order to improve the service life of the airbag and shock absorber, the air in the airbag needs to be stored by the airbag tank, and the sealing performance of the airbag tank is very important to the quality of the air suspension. At present, the domestic inspection method of the airbag tank is that the middle ejector rod is directly pressed against the product, and there is a lack of pressing block. The small pressing surface is easy to damage the airbag tank, and the airtightness of the middle stud cannot be accurately detected, and other auxiliary detection devices are needed. , because the fixed seat does not ad...

Problems solved by technology

At present, the domestic inspection method of the airbag tank is that the middle ejector rod is directly pressed against the product, and there is a lack of pressing block. The small pressing surface is easy to damage the airbag tank, and the airtightness of the middle stud cannot be accurately detected, and other auxiliary detection devices are needed. , because the fixed seat does not adopt a groove structure, the tightness of the compression rubber 6 cannot be better guaranteed, and the standard airbag tank φ102.5, φ132.5, φ152.5, φ199.7 bayonet size detection is not universal, Every time you need to replace the snap-size rubber pad
