A quenching device for heat treatment of a piston rod comprises a quenching table, a machining table is arranged in the quenching table, the piston rod is movably inserted into the top of the machining table, a hydraulic telescopic rod is fixedly installed at the bottom of the machining table, a hydraulic machine is fixedly installed at the bottom of the quenching table, and the output end of the hydraulic machine is fixedly connected with the hydraulic telescopic rod; the utility model has the following advantages: the first motor is started to drive the worm and gear to rotate, so that the threaded rod rotates to adjust the position of the heating cylinder to wrap the piston rod, the high-frequency quenching electric coil in the heating cylinder heats and quench the piston rod, and then the hydraulic machine is started to adjust the position of the hydraulic telescopic rod to adjust the machining table; and thus, the quenched piston rod is moved to the position below the spraying head, the piston rod is coo
