Automatic machining system for traction machine base

The invention discloses an automatic machining system for a traction machine base. The automatic machining system comprises a plurality of vertical lathes, a plurality of horizontal machining centers, a carrying robot, a feeding and discharging station, a safety device, a control system and a zero-point positioning clamp. The vertical lathe is arranged on one side of the moving path of the transfer robot, and the horizontal machining center and the feeding and discharging station are arranged on the other side of the moving path of the transfer robot. The carrying robot is used for carrying the traction machine base among the vertical lathes, the horizontal machining center and the feeding and discharging station. The safety device at least comprises a fence, a grating, a safety door and a scram button; the zero-point positioning fixture is used for fixedly connecting the traction machine base with a vertical lathe or a horizontal machining center, so that the traction machine base is positioned during machin
