Industry Application | Automated Processing of Pickup/Off-Road Vehicle Axle Housings

The automotive axle housing is an important component of the vehicle chassis system. It, along with the main reducer, differential, and wheel drive device, forms the drive axle, where strength and high steel performance are crucial. This article introduces the machining automation solutions provided by Beijing Smart Technology Co., Ltd. for the processing of drive axle housings for pickup trucks and off-road vehicles. It is hoped that these solutions will help customers reduce work errors and manual input, improve production efficiency, and support their continuous, stable, and efficient production.


The automotive bridge shell is an important component of the vehicle chassis system. It, along with the main reducer, differential, and wheel drive device, forms the drive axle, where its strength and high steel performance are crucial. This article introduces the machining automation solutions provided by Beijing Smart Technology Co., Ltd. for the processing of drive axle shells for pickups and off-road vehicles, hoping to help customers reduce work errors and labor input, improve production efficiency, and support their continuous, stable, and efficient production.

Processing difficulties:

The drive axle shells for pickups and off-road vehicles belong to long-axis type parts, and the processing technology is relatively concentrated. The difficulties in processing lie in the large welding errors, susceptibility to deformation, uneven residuals, and tendency to vibrate. If the production line design is unreasonable, it will affect tool life and the overall stability of the processing.


Solutions:

The bridge shell machining line designed by Beijing Smart Technology Co., Ltd. can be used for the processing of various models of axle shells. The product's blank state is a welded assembly, which has characteristics of large welding errors and unstable thermal deformation. Therefore, we adopted a combination of Dean machine tools (formerly "Doosan Machine Tools") CNC lathes, vertical machining centers, and modern robots to complete the processing of the bridge shell end face, outer circle, hole positions, and installation surfaces.

Results:

By using Dean machine tools (formerly "Doosan Machine Tools") for line processing with turning and milling composite equipment, the applicability of the tool fixtures is quite broad, helping customers achieve high output with low investment. Its design and processing effects are stable, dimensions meet customer standards, and tool life fully satisfies customer requirements. Currently, Beijing Smart Technology Co., Ltd. has successfully delivered a series of manual and automated processing lines for shells, and in the future, will continue to follow customer needs for ongoing research and innovation, looking forward to collaborating with more industry clients in various aspects.
