Abstract
The utility model relates to a pressure interlock riveted structure for aluminum alloy material connects belongs to aluminum alloy material's connection structure. One end of the hollow riveting bush is in compression joint with the upper surface of the pipe wall of the aluminum pipe through the annular boss, the hollow riveting bush penetrates through the aluminum pipe, and the other end of the hollow riveting bush is in riveting connection with the lower pipe wall of the aluminum pipe through knurling. The advantage is novel structure, through pressure interlock riveted structure realization aluminum pipe and the being connected of bush, the aluminum pipe has increased the structure back of riveting the bush, can have higher design degree of freedom, can realize through the bush with the connection of more products, and need not use aluminium welding process, has energy-concerving and environment-protective for the aluminum pipe welding, and size stability, precision are high, and the ejection force is greater than 2000N after the riveting is accomplished, and the practicality is good, is fit for the development of automobile parts in the future.
Description
Technical Field
The utility model belongs to aluminum alloy material's connection structure especially indicates a pressure interlock riveted structure that is used for aluminum alloy material to connect.
Background
The light weight of the automobile is the development direction of the automobile industry all over the world, the first choice material of the light weight of the automobile is aluminum alloy, and the application of the aluminum alloy material in the automobile has important significance for solving the problems of energy shortage, environmental pollution and low transportation efficiency in China. Most car bodies are welded and assembled, and the welding of aluminum is more difficult than that of steel, so the aluminum alloy connecting technology is closely related to the development of the current automobile industry.
Disclosure of Invention
The utility model provides a pressure interlock riveted structure for aluminum alloy material connects to the degree of difficulty that exists when solving aluminum alloy material welding equipment is big, the unstable problem of quality.
The utility model discloses the technical scheme who takes: one end of the hollow riveting bush is in compression joint with the upper surface of the pipe wall of the aluminum pipe through the annular boss, the hollow riveting bush penetrates through the aluminum pipe, and the other end of the hollow riveting bush is in riveting connection with the lower pipe wall of the aluminum pipe through knurling.
The hollow riveting bush is made of 7-series aluminum alloy.
The wall thickness of the hollow riveting bushing is larger than 3 mm.
The knurling depth of the hollow riveting bush is more than 2 mm.
The aluminum pipe is made of 5 series aluminum alloy or 6 series aluminum alloy.
The wall thickness of the lower pipe wall of the aluminum pipe is larger than 2 mm.
The utility model has the advantages of novel structure, realize being connected of aluminum pipe and bush through pressure interlock riveted structure, the aluminum pipe has increased after the structure of riveting bush, can have higher design freedom, can realize through the bush with the connection of more products, and need not use aluminium welding process, it is energy-concerving and environment-protective to have for the aluminum pipe welding, and size stability, precision are high, and the jacking force is greater than 2000N after the riveting is accomplished, and the practicality is good, is fit for future automobile parts's development.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a sectional view A-A of the present invention;
FIG. 3 is a schematic structural view of the hollow rivet bush of the present invention;
fig. 4 is a schematic view of the present invention in a connected use state.
Detailed Description
Referring to fig. 1 and 2, one end of a hollow riveting bush 1 is pressed and connected with the upper surface 201 of the pipe wall of an aluminum pipe 2 through an annular boss 101, the hollow riveting bush 1 penetrates through the aluminum pipe 2, and the other end of the hollow riveting bush is riveted and connected with a lower pipe wall 202 of the aluminum pipe 2 through knurling 102;
the hollow riveting bush 1 is made of 7-series aluminum alloy;
the wall thickness of the hollow riveting bushing 1 is more than 3mm, otherwise, the strength of the bushing is insufficient;
with reference to fig. 3, the depth of the knurl 102 of the hollow rivet bush 1 is greater than 2mm, which would otherwise result in insufficient connection strength;
the aluminum pipe 2 is made of 5 series aluminum alloy or 6 series aluminum alloy;
the lower tubular wall 202 of the aluminium tube 2 has a wall thickness of more than 2mm, which otherwise results in insufficient joint strength.
Principle of operation
Referring to fig. 4, the aluminum pipe 2 is fixedly connected with the connected member 4 by bolts 3 passing through the hollow caulking bush 1, and the aluminum pipe 2 is effectively prevented from being deformed by pressure at the time of connection due to the large strength of the hollow caulking bush 1.
