Lightweight cab is both a goal to reduce the weight of the structure itself cab lights, but also to ensure the cab of passive safety, structural strength, stiffness, vibration characteristics and durability of the cab shell, while minimizing cab no major increase in manufacturing costs. In meeting the structural performance and safety of the premise, lightweight design of the cab structure, in order to save material, reduce costs, save energy and reduce vehicle emissions, which is the current requirement of common automobile manufacturers. Previous studies and experimental results show that 10% of cars every weight, reduce fuel consumption by 6% to 8% emission reduction of 4% to 6%. Commercial vehicle cab BIW can be viewed as a complex stamping welded structure, the structure of vehicle general arrangement design to meet the requirements and have sufficient structural strength to withstand a static load and car suffered during operation various dynamic load, it must have sufficient rigidity to ensure the cab and assembly, components mounted thereon work properly in cars with a variety of conditions; cab must also ensure that there is adequate security. Therefore, to ensure rigidity, strength, vibration characteristics, passive safety requirements of the premise, lightweight design of the cab structure, commercial vehicle cab BIW design work in a very important welding wire before the welding through the assembly line is a flexible semi-automatic welding line, the production program of 50,000, across the board a total of eight steps, step spacing 4m cab, beat 4min, a total length of 34m. BIW flexible positioning and clamping function is performed by eight sets of fixed welding fixture. Inter-process product transportation methods using reciprocating rod can lift drive mechanism, and is equipped with 2 automatic welding process 12 "automatic welding equipment" for the process of welding jig 2 is equipped with a hydraulic system. A full range of welding clamp, transmission, matching and interlocking between the action thanks to the automatic welding equipment electrical control.
