[0034] First, place the workpiece to be quenched on the top of the placement plate 25, the center of which is passed through by the positioning shaft 26, and the driving motor 6 drives the threaded rod 5 to rotate. The threaded rod 5 is used in conjunction with the threaded hole 4 to push the guide block 3 to slide on the outside of the auxiliary rod 8. The auxiliary hole 7 is used in conjunction with the auxiliary rod 8, so that the guide block 3 can maintain balance during the sliding process. When the placement plate 25 is moved to the inside of the quenching box 28, the lifting and lowering begins to descend, so that the placement plate 25 stays inside the quenching box 28, and the telescopic rod 12 begins to contract, driving the slide The rod 11 slides downward inside the installation tube 10, and the connecting frame 16 pushes the connecting rod 15, so that the clamping plate 14 rotates outward inside the support plate 13 until the clamping plate 14 is away from the positioning block 27. The lifting rod 9 begins to shrink, so that the clamping plate 14 is away from the quenching box 28, and the workpiece begins to be quenched and heated. After the quenching and heating of the workpiece is completed, the lifting rod 9 extends downward to an appropriate position, and the telescopic rod 12 begins to extend with the moving slide rod 11 to move upward. The connecting rod 15 and the connecting frame 16 are used to pull the clamping plate 14 to fit the outer side of the positioning block 27. The driving motor 6 drives the threaded rod 5 to rotate, so that the guide block 3 drives the placement plate 25 to move toward the placement rack 18, and the workpiece stays on the placement rack 18. The lifting device 22 drives the placement rack 18 to move upward, so that the workpiece is higher than the top of the positioning shaft 26, and then the universal wheel 24 is used to push the material transport mechanism 17 to move the quenching liquid workshop to perform quenching work. The unheated workpieces can be placed on the top of the placement rack 18 in sequence, arranged in order, corresponding to the position of the positioning shaft 26, and the universal wheel 24 is used again to push the material transport mechanism 17 to move to the bracket 1 At the bottom, at this time, the placement plate 25 and the positioning shaft 26 are both at the bottom of the placement rack 18. The lifting device 22 is used to drive the placement rack 18 to move downward and fit against the top of the placement plate 25. The center hole of the workpiece has been penetrated by the positioning shaft 26. The drive motor 6 is used to drive the threaded rod 5 to rotate and push the guide block 3 to move toward the quenching box 28 for quenching. When the quenched parts are moved to another place by the material transport mechanism 17, the servo motor 20 drives the placement rack 18 to rotate, so that the workpiece falls off the ground.
