The invention discloses a steel bar end milling and rolling integrated machine for steel bar thread processing. The steel bar end milling and rolling integrated machine for steel bar thread processingcomprises a bottom plate; a cavity is formed in the bottom plate; a spindle screw rod and a sliding block are arranged in the cavity; a threaded hole is formed in the middle of the sliding block, isprovided with an inner thread and is in threaded connection with the spindle screw rod; and a mounting base is welded to the sliding block. The steel bar end milling and rolling integrated machine forsteel bar thread processing has the advantages that three fixing screw rods can be driven to rotate relative to a square block by rotating any one handle, the square block is made to slide in the radial direction to enable arc clamping plates to tightly clamp steel bars, and it is ensured that a milling assembly can form threads of higher precision in a milling mode; after the milling assembly completes the thread processing, an electromagnetic heating ring carries out electromagnetic heating on the ends of the steel bars till the ends reach the red hot state, and good thermoplasticity is achieved; and when the ends of the steel bars collide with the bottom of a rolling groove repeatedly, internal limiting of the ends of the steel bars can be tighter, and therefore the threads at the endsof the steel bars have higher strength.
