Abstract
The invention relates to an automobile body part, in particular to a thread structure on an aluminum alloy casting. The thread structure comprises an aluminum alloy casting body, wherein a plurality of steel nut sleeves are arranged on the aluminum alloy casting body and are cast integrally with the aluminum alloy casting body. Before the aluminum alloy casting body is produced by die casting, the steel nut sleeve is assembled in a die, molten aluminum alloy casting is solidified to form threads which are meshed with the external threads of the steel nut sleeve in the die casting process, and the part forming and the assembly of the steel nut sleeve are completed by one-step casting. The invention adopts the embedded nuts and casts the embedded nuts into a whole, does not need to meet the requirement of high-precision machining of the aluminum alloy casting threads, can effectively avoid the quality problem caused by assembly and meets the requirement of repeated disassembly and assembly.
Description
Technical Field
The invention relates to an automobile body part, in particular to a thread structure on an aluminum alloy casting.
Background
The automobile generally adopts light materials such as aluminum alloy and the like to realize the lightweight requirement, the advantages of automobile body aluminum alloy castings are gradually obvious, and the production efficiency can be improved through integrated forming. The aluminum alloy casting is mainly applied to a vehicle body framework and provides a mounting structure for other systems, but the related mounting thread specifications and mounting torsion of parts such as a chassis auxiliary frame and the like are large, the use working condition of the automobile is severe, and the requirement on the thread strength of the aluminum alloy casting is high. At present, the scheme commonly adopted by mass production vehicles at home and abroad is that a steel wire thread bushing is embedded after a thread is added on an aluminum alloy casting machine, the assembly process is complex and has low automation rate, the required thread machining precision is high, the failure rate is higher, the maintenance scheme is complex, and the cost is high.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a scheme of the aluminum alloy casting pre-cast steel thread structure, the steel nut sleeve is pre-embedded in the aluminum alloy casting body in the aluminum alloy casting process, and the aluminum alloy casting pre-cast steel thread structure is simple in structure, high in thread strength, high in reliability and high in production efficiency.
The technical scheme is that the thread structure on the aluminum alloy casting comprises an aluminum alloy casting body, wherein a plurality of steel nut sleeves are arranged on the aluminum alloy casting, and the steel nut sleeves and the aluminum alloy casting are cast into a whole.
Specifically, one end of the steel nut sleeve is closed.
Furthermore, the steel nut sleeve is provided with an external thread.
Preferably, the external thread is a coarse thread.
Particularly, a flange plate is arranged at the opening end of the steel nut sleeve.
Preferably, the flange plate is provided with bosses at intervals.
Specifically, the closed end of the steel nut sleeve is hemispherical.
Furthermore, the number of the steel nut sleeves is 2.
Particularly, before the aluminum alloy casting body is subjected to die casting, the steel nut sleeve is assembled in a die, molten liquid of the aluminum alloy casting body is solidified to form threads which are meshed with the external threads of the steel nut sleeve in the die casting process, and the part forming and the assembly of the steel nut sleeve are completed through one-step casting.
The invention has the beneficial effects that: the utility model provides an aluminum alloy casting cast steel thread structure scheme in advance, steel nut is pre-buried at the aluminum alloy casting body in the aluminum alloy casting process, its simple structure, and screw thread strength is high and the reliability is high, and production efficiency is high. Compared with a steel wire thread sleeve and a thread nesting, the invention adopts the embedded nut and casts the embedded nut into a whole, does not need to meet the requirement of high-precision machining of the aluminum alloy casting thread, can effectively avoid the quality problem caused by assembly and meets the requirement of repeated disassembly and assembly.

Detailed Description
Examples
As shown in fig. 1 to 8, the thread structure of the present invention includes an aluminum alloy casting body 1, wherein a plurality of steel nut sleeves 2 are disposed on the aluminum alloy casting body 1, and the steel nut sleeves 2 are cast integrally with the aluminum alloy casting body 1. One end of the steel nut sleeve 2 is closed. And the blind hole is adopted, so that the internal thread 7 can be effectively prevented from being polluted by cast aluminum scraps. And a flange plate 6 is arranged at the opening end of the steel nut sleeve 2. The flange plate is positioned at the joint of the steel nut sleeve and the aluminum alloy casting body, so that the impact resistance of the structure can be improved.
In a preferred embodiment, the steel nut sleeve 2 is provided with an external thread 3. And bosses 4 are arranged on the flange 6 at intervals. The boss is used for spacing steel nut cover, ensures screw thread intensity. Simultaneously, set up boss and aluminum alloy casting body meshing, effectively promote the moment of torsion, dismouting many times can not lead to the nut to withdraw from even aluminum alloy casting screw thread wearing and tearing.
In a preferred embodiment, the external thread 3 is a coarse thread. The closed end 5 of the steel nut sleeve 2 is hemispherical. The hemispherical shape can avoid the influence of the turbulence generated by the aluminum liquid on the quality of the cast thread in the casting process.
In another embodiment, the number of the steel nut sleeves is 2.
In another embodiment, before the aluminum alloy casting body 1 is subjected to die casting, the steel nut sleeve 2 is assembled in a die, molten liquid of the aluminum alloy casting body 1 is solidified to form threads which are meshed with the external threads 3 of the steel nut sleeve 2 in the die casting process, and the part forming and the assembly of the steel nut sleeve 2 are completed through one-step casting.
