Half shaft machining process

Abstract

The invention discloses an automobile half shaft machining process. The automobile half shaft machining process comprises 1, laying off raw materials entering the factory; 2, forging the half shaft; 3, carrying out thermal refining to the half shaft; 4, carrying out a rough shot blasting step; 5, carrying out a rough correction step; 6, carrying out rough turning to the long shaft of the half shaft and drilling a center hole; 7, calculating the total length of the half shaft and drilling a center hole; 8, grinding the center hole; 9, carrying out finish turning to the rod portion of the half shaft and cutting a thread; 10, carrying out gear rolling to the half shaft; 11, carrying out medium-frequency hardening heat treatment to the surface; 12, carrying out a tempering step; 13, carrying out a fine correction step; 14, carrying out supersonic flaw detection; 15, carrying a fine shot blasting step; 16, grinding the center hole; 17, carrying out finish turning to a disc structure of the half shaft; 18, drilling a hole; 19, cutting a thread; 20, grinding the shaft neck; 21, carrying out magnetic powder flaw detection; and 22, carrying out total detection. By employing the improved half shaft machining process, the carrying amount for machining is reduced, the machining quality of the half shaft is improved at the same time, the fact that the machined half shaft is without inner flaws is guaranteed, the half shaft machining process is simple to operate, and the coaxial consistency is high.
