Description
The technical field is as follows:
the utility model belongs to the technical field of the automobile manufacturing, especially, relate to automobile body floor crossbeam and threshold roof beam connection structure.
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: automobile body floor crossbeam and threshold roof beam connection structure II connects, floor crossbeam and threshold roof beam including the aluminium alloy, the aluminium alloy connects and is connected face and third by first connection face, second and connect face integrated into one piece equipment, integrated into one piece is provided with the enhancement face between first connection face, the second connection face, the third is connected the face right-hand member and is provided with the reinforcement body of sharp mouth form, first connection face, the second connection face that the aluminium alloy connects are through FDS connected mode fixed mounting on the floor crossbeam, the third connection face that the aluminium alloy connects is through self-plugging rivet fixed connection on the threshold roof beam.
Preferably, a positioning clamping groove is formed between the first connecting surface and the third connecting surface, and the floor beam is clamped in the clamping groove.
Preferably, the reinforcement body of the aluminum profile joint and the sill beam are subjected to repair welding by MIG welding.
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 self-plugging rivets, 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 top view of an aluminum profile joint.
Fig. 2 is a front view of the aluminum profile joint.
Fig. 3 is a perspective view of the aluminum profile joint.
Fig. 4 is a schematic plan view of a connection structure of an aluminum profile joint and a floor cross member.
Fig. 5 is a plan view of an aluminum section joint, floor cross member and threshold beam assembly structure.
Fig. 6 is a perspective view of an aluminum profile joint, floor cross member and threshold beam assembly structure.
The specific implementation mode is as follows:
the present invention will be described in detail with reference to the following embodiments:
as shown in fig. 1 to 6 vehicle body floor crossbeam and threshold roof beam connection structure II, connect 1, floor crossbeam 2 and threshold roof beam 3 including the aluminium alloy, the aluminium alloy connects 1 and is connected 12 and the third by first connection face 11, second and is connected 13 integrated into one piece equipment, integrated into one piece is provided with reinforced face 14 between first connection face 11, the second is connected 12, the third is connected 13 right-hand members and is provided with sharp mouth form reinforcement 15, the first connection face 11 that the aluminium alloy connects 1, second are connected 12 and are passed through FDS connected mode 4 fixed mounting on floor crossbeam 2, the third that the aluminium alloy connects 1 is connected 13 and is passed through self-plugging rivet 5 fixed connection on 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 3 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 the self-plugging rivet 5, so that the floor beam, the aluminum section joint and the threshold beam are connected.
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.
Be located and be convenient for fix a position between floor crossbeam 2 and the aluminium alloy connects 1, form positioning groove 16 between first connection face 11 and the third connection face 13, floor crossbeam 2 card is in draw-in groove 16.
