[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a heat treatment quenching lifting device, comprising a water tank 1, an assembly frame 2 and a fixing frame 3. The assembly frame 2 is provided on the left side of the water tank 1, and a lifting mechanism is provided on one side of the assembly frame 2. One end of the lifting mechanism is connected to an electric heating mechanism. The fixing frame 3 is fixed on the back side of the water tank 1. A nozzle 14 is installed on the top of the fixing frame 3. A water delivery mechanism is provided between the water tank 1 and the nozzle 14. A drain pipe 18 is connected to the right side of the water tank 1. A support platform 4 is provided inside the water tank 1. A fixing mechanism is provided on the top of the support platform 4. The metal shaft is fixed to the top of the support platform 4 through the fixing mechanism. The lifting mechanism drives the electric heating mechanism to reciprocate up and down to heat the entire metal shaft until it reaches a critical temperature. The water delivery mechanism delivers the water stored in the water tank 1 to the inside of the nozzle 14. The nozzle 14 sprays water to the metal shaft to automatically quench it, and the metal shaft is reciprocated during the quenching process, which saves the time of quenching work and improves its work efficiency.

[0020] The fixing mechanism includes a pneumatic rotary chuck 11, a cylinder 12 and a vent pipe 13. The pneumatic rotary chuck 11 is provided on the top of the support platform 4, and the cylinder 12 is installed on the front of the water tank 1. The output end of the cylinder 12 is connected to the inside of the pneumatic rotary chuck 11 through the vent pipe 13. The cylinder 12 drives the piston to generate working air pressure, and transmits it into the inside of the pneumatic rotary chuck 11 through the vent pipe 13, so that the jaws of the pneumatic rotary chuck 11 generate clamping force, and the metal shaft is clamped on the top of the pneumatic rotary chuck 11. The cylinder 12 extracts the working air pressure inside the pneumatic rotary chuck 11, so that the jaws can be separated from the metal shaft. At this time, the metal shaft after quenching can be taken out.
