Background art:
aluminum has the advantages of low density and light weight. Aluminum is a good material from the viewpoint of weight reduction, but parts formed from aluminum plates are expensive in manufacturing dies, difficult to form, and inferior in strength and rigidity to steel parts. Parts of aluminum profile construction, which are inherently strong and rigid, are extruded with a constant cross-section during manufacture, are inexpensive to manufacture, and therefore aluminum is often found on vehicle bodies in the form of profiles. The common connection mode for connecting the profiles is MIG welding and riveting. And during MIG welding, parts are large in deformation, and the precision is difficult to guarantee. Because of riveting equipment occupation space is big, weight is heavy during the riveting, there is very big limitation in connecting between section bar and the section bar spare, and structural space is not enough often leads to riveting technology to realize. A connection structure for solving the problem of connection between aluminum profiles is urgently needed.
The invention content is as follows:
the utility model discloses the technical problem that will solve is: the problem that riveting cannot be performed due to the fact that riveting equipment occupies a large space when aluminum profiles are connected is solved. Design a section bar joint promptly, connect the riveting through the section bar between the aluminium alloy, the tie point after the riveting has sufficient intensity and rigidity, can satisfy the automobile body rigidity requirement, and the riveting process is simple more high-efficient simultaneously, has simplified riveting process, lets riveting technique use more generally on the automobile body.
In order to solve the technical problems, the invention is realized by the following technical scheme: the utility model provides an automobile body floor crossbeam and threshold roof beam connection structure I, includes that the aluminium alloy connects, floor crossbeam and threshold roof beam, the aluminium alloy connects first connection face, second connection face and the third connection face that includes integrated into one piece, the first connection face that the aluminium alloy connects passes through FDS connected mode fixed connection on the floor crossbeam, the second connection face that the aluminium alloy connects is fixed through FDS connected mode with the inboard vertical plane of threshold roof beam, the third connection face that the aluminium alloy connects passes through self-plugging rivet fixed connection between the tip of threshold roof beam.
Preferably, a reinforcing rib is arranged between the first connecting surface and the second connecting surface of the aluminum profile joint.
Preferably, the contact area of the aluminum section bar joint and the floor beam and the doorsill beam is fixedly connected through MIG repair welding.
Preferably, the first connecting surface, the second connecting surface and the third connecting surface of the aluminum profile joint are provided with pre-positioning holes.
Compared with the prior art, the utility model discloses an useful part is: the floor beam, the threshold beam and the joint are connected, the floor beam, the threshold beam and the joint are positioned and clamped through a tool clamp, riveting is completed through FDS and loose core riveting, and the assembly connecting point after riveting has enough rigidity and strength. Floor crossbeam, threshold roof beam and joint are aluminium extruded section bar, do not have the mould expense, because of riveting joint reasonable design during the riveting, the technology is simpler, connects more reliably.
Description of the drawings:
the present invention will be further explained with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of an aluminum profile joint.
Fig. 2 is a schematic view of a connection structure of an aluminum profile joint and a floor beam.
FIG. 3 is an outer side view of the connection assembly.
FIG. 4 is an inner side view of the connection assembly.
The specific implementation mode is as follows:
the present invention will be described in detail with reference to the following embodiments:
as shown in figures 1 to 4 a vehicle body floor crossbeam and threshold roof beam connection structure I, connect 1, floor crossbeam 2 and threshold roof beam 3 including the aluminium alloy, the aluminium alloy connects 1 to be connected 12 and third including integrated into one piece's first connection face 11, second and is connected 13, the aluminium alloy connects 1 first connection face 11 to pass through FDS connected mode fixed connection on floor crossbeam 2, the aluminium alloy connects 1 second to be connected 12 and is fixed through FDS connected mode with the interior vertical plane of threshold roof beam 3, the aluminium alloy connects 1 third to be connected 13 and is passed through self-plugging rivet 4 fixed connection between the tip of threshold roof beam 3.
Assembling the floor beam 2 and the aluminum section joint 1, positioning and clamping the two parts by using a tool clamp, and connecting and fixing the two parts through an FDS (fully drawn sheet metal) process to form a first assembly. And assembling the first component and the threshold beam together, positioning and clamping the two parts by using a tool clamp, and connecting and fixing the first component and the threshold beam by using an FDS (fully drawn yarn) process and a self-plugging rivet 4 to complete the connection of the floor beam, the joint and the threshold beam.
The core of the invention is to control the matching relation between the size of the connector and the size of the cross section of the floor beam by designing the extruded section connector. And (3) positioning and clamping the joint and the floor beam through a tool clamp within a manufacturing tolerance range, fixing the joint and the floor beam by using FDS (fully drawn yarn) to form an assembly, positioning and clamping the assembly and the sill beam through the tool clamp, and fixing the assembly and the sill beam together by using FDS and high-strength self-plugging rivets. The assembly sequence of the floor beam, the threshold beam and the joint can be changed. For example, the joint is first connected and fixed to the floor cross member to form an assembly, and then connected to the sill beam, or the joint is first connected and fixed to the sill beam to form an assembly, and then connected to the floor cross member. The installation sequence can be flexibly selected according to the convenience in actual assembly.
