Section bar pressure riveting threaded sleeve structure

Technical Field

The utility model relates to a swivel nut technical field that connects specifically relates to a swivel nut structure is riveted to section bar pressure.

Background

With the deep application research of the aluminum alloy, the material advantages of the aluminum alloy are more and more obvious. Mainly characterized by good corrosion resistance, light weight and strong impact resistance of the material. The process method is well continuous on the basis of steel. The method also has good performance on the integration capability of the aluminum casting.

The technology of aluminum profiles is more and more mature, the application of the aluminum alloy is more and more extensive, and the aluminum alloy is not only applied to aerospace, but also widely applied to the field of new energy automobiles. The connection mode is more and more diversified, such as: sleeve screw connection, SPR connection, RPS connection, MIG welding, MAG welding and the like are adopted. The morphology and processing of components is also becoming more and more diverse, such as: the steel is connected with the aluminum, the aluminum profile is connected with the aluminum plate, and the aluminum plate is connected with the aluminum plate. And (4) connecting the aluminum alloy with the aluminum casting.

These molding methods and connecting methods allow more and more freedom in design and allow more and more space to be available. Particularly, in the field of new energy automobiles, the application of automobile bodies, battery packs and the like is not limited to the use of common steel plates and high-strength steel plates, but the application is multi-material and multi-application, and a large amount of aluminum alloy is added into parts. The further light weight of the product is realized, and the impact resistance of the product is improved.

But the aluminum material has larger resilience and strong heat conduction capability, is more difficult to process and form compared with steel materials, and increases the cost once each more process. In particular, the aluminum profile has an equal cross section and is formed into an integral shape, so that the aluminum profile is not easy to be processed again. Namely, the design features are difficult to stamp on the sectional material, the application scope of the sectional material is directly reduced, such as sealing performance, installation reliability and the like, and the design difficulty is increased.

At present, the connection of all components is generally realized through threaded sleeves arranged on aluminum profiles, and the installation of various products under the processes of various aluminum profiles, aluminum extrusion, rollers and the like is related. Particularly in the technical field of battery boxes, and in the fields of vehicle body connection, installation and the like. As shown in fig. 1 and 2, the existing thread insert generally has the following problems:

1. the design of the components is limited: in order to avoid the turnbuckle nut, a special structure for solving the problem of poor surface needs to be designed. The design volatility is influenced, and more external space is occupied. Meanwhile, the process complexity is increased, so that the production cost is improved, and the production efficiency is reduced.

2. Component mounting limitations: in order to avoid the flange surface of the sleeve, avoiding features such as bosses and the like are added in the design, the space distance between the parts in the radial direction of the flange surface is increased, the installation stability is reduced, meanwhile, the stamping process is added, and the process complexity of the product is improved.

3. The components are limited in sealing: the nut on the conventional screw sleeve protrudes out of the main body material, and the flange surface and the surface of the main body of the component have surface difference due to different characteristics of the component. A gap in the mounting direction, or a radial gap, may occur. Making installation and sealing difficult.
