Research On Key Technologies In Assembly Line Of Auto Axle Shaft

Axle shaft is one of important parts in auto drive system, which directly transfers the torque from axle shaft gear to driving wheel, and its assembly precision will directly influence or decide the precision of drive axle. Based on analyzing lots of special books and literature data, in this paper the assembly line of auto axle shaft (MPV) for Hefei axle stock co.,ltd is designed and the key technologies are studied referring to application production all over the world,.Firstly, the actuality and development trend of auto assembly line all over the world is introduced and some common methods of calculating working procedure time are refered. Then through analyzing the structure of axle shaft (MPV), combining the workshop and existing equipments in Hefei axle stock co.,ltd, it designs a asynchronous annular assembly line, and aiming at actual peculiarity of the assembly line, systemically works over some important key technologies, such as: reasonable choosing of the press machine, the experiment of arrester pump.With assembly experiment and measurement on the spot, it is proved the assembly line can largely advance the efficiency and quality of auto axle shaft, and can also improve whole capability of driving axle.
