Automatic quenching production system for constant velocity universal joint

The invention relates to the technical field of universal joint quenching, in particular to an automatic quenching production system for a constant velocity universal joint. Comprising a machine tool, a workbench arranged on one side of the machine tool, a discharging table arranged on the other side of the machine tool, a rod part quenching grabbing mechanical arm arranged close to the machine tool, an inner cavity quenching grabbing mechanical arm arranged on the adjacent side of the rod part quenching grabbing mechanism, and a rod part quenching mechanism arranged in the machine tool. The inner cavity quenching mechanism is arranged on the adjacent side of the rod part quenching mechanism; the transition grabbing manipulator is used for transferring the universal joint subjected to rod part quenching to the inner cavity quenching mechanism; and the flue gas recycling mechanism is arranged above the rod part quenching mechanism and is used for collecting flue gas generated during quenching.
