Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, and in particular to a casting aluminum front shock absorber tower assembly connection tooling, connection system and connection method. Background Technology

[0002] Lightweighting of automobiles aims to reduce the vehicle's curb weight as much as possible while ensuring its strength and safety performance, thereby improving its power, reducing fuel consumption, and lowering exhaust emissions. Experiments have shown that reducing a car's weight by half can reduce fuel consumption by nearly half. Due to environmental protection and energy conservation needs, lightweighting has become a global trend in automotive development. The key to lightweighting is weight reduction, and using lightweight materials is a crucial means to achieve this. Aluminum alloys have a density approximately one-third that of steel, and possess high specific strength and good corrosion resistance. Due to their excellent comprehensive performance and outstanding lightweight value, they have become the mainstay in the field of automotive lightweight materials. Currently, with advancements in aluminum alloy die-casting technology, the performance of large, complex, thin-walled aluminum alloy die-cast parts has been significantly improved, and their application in vehicle bodies is gradually being promoted. Shock absorber towers are important load-bearing structural components of the vehicle body. To achieve vehicle lightweighting, shock absorber tower materials are transitioning from traditional steel plates to cast aluminum.

[0003] like Figure 1 The diagram shows a cast aluminum front shock absorber tower assembly, including a front shock absorber tower 61 and a first sheet metal 62, a second sheet metal 63, and a third sheet metal 64 connected around it. There are numerous connection points between the front shock absorber tower 61 and the three sheet metals, requiring precise positioning. Relying solely on standard fixtures available on the market cannot fully position this type of complex machined part, potentially leading to risks due to inaccurate positioning during the connection process.

[0004] Furthermore, due to the significant differences in chemical properties between steel and aluminum, the cast aluminum front shock absorber tower cannot be connected to the surrounding steel body panels using traditional welding methods. Only mechanical connection processes such as SPR and FDS can be employed. The steel body panels surrounding the cast aluminum front shock absorber tower still require traditional spot welding. Therefore, it is necessary to upgrade the existing welding production line or establish a dedicated steel-aluminum hybrid automated production line to meet the production requirements of the front shock absorber tower assembly. The cast aluminum front shock absorber tower assembly has a symmetrical structure. If a single-station production method is used, manual switching of the left and right side tooling fixtures is required, and the robot frequently switches between different types of connection guns, impacting production efficiency. While using two independent workstations saves fixture switching time, it requires more space. Without increasing the number of robots, single-station production is still the only option, and frequent gun changes still occur, affecting production efficiency. Summary of the Invention
