The Design of Special Knuckle CNC Lathe

Taken the special knuckles CNC lathe as an object of study in the paper,profile automobile steering bar and the main processing of big face have been discussed and the lack of using usual horizontal lathes and simple horizontal CNC lathe machining steering bar and flange surface processing technology are analyzed,and the use of special vertical CNC lathe machining steering bar and the main process have been supplied.This paper gives the main structure of the knuckles special vertical CNC lathe,the working circle of the machine and the main technical parameters of the machine.Then the key components of spindle box,feeding system and fixture of the knuckles special vertical CNC lathe have been designed.The using result of this machine suggests that the technology thus effectively guarantee the stem and knuckles with two big face top hole position precision,and effectively reduce the labor intensity and unloading work pieces.
