[0038] like Figure 3 and Figure 6 As shown, the lifting component 25 includes a mounting plate 251 arranged at the lower end of the rotating driving component 22, and a first electric telescopic rod 252 is fixedly connected to the lower end of the mounting plate 251. The inner side of the inner gear ring 24 is fixedly connected to the upper end of the mounting plate 251 through a Z-shaped axis. The first electric telescopic rod 252 is used to adjust the height of the mounting plate 251 and the rotating driving component 22, and the mounting plate 251 is used to support the inner gear ring 24.

[0039] like Figure 6As shown, the rotating driving component 22 includes an outer gear ring 221 fixedly connected to the lower end of the rotating disk 21 through a shaft, a connecting column 222 is rotatably connected at the center of the lower end of the rotating disk 21, and the lower end of the connecting column 222 is fixedly connected to the upper end of the mounting disk 251, and the upper end of the mounting disk 251 is fixedly connected to the second motor 224, and the output end of the second motor 224 is fixedly connected to the first gear 223, and the first gear 223 is meshingly connected to the outer gear ring 221, and the second motor 224 is used to drive the rotating disk 21 to rotate.

[0040] like Figure 3 and Figure 6 As shown, the lifting component 26 includes a telescopic sleeve rod 261 rotatably connected to the lower end of the end face gear 133 and a bent rod 262 fixedly connected to the outer surface of the telescopic sleeve rod 261.

Through the extension and retraction of the telescopic sleeve rod 261, the bent rod 262 can adapt to the lifting and lowering of the rotating disk 21.

[0041] like Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, the display component 23 includes a transmission shaft 231 that is rotatably connected to the rotating disk 21, the lower end of the transmission shaft 231 is fixedly connected to the second gear 232, and the second gear 232 is meshed with the inner side of the inner gear ring 24, the upper end of the transmission shaft 231 is rotatably connected to the display arc plate 233, the upper end of the display arc plate 233 is fixedly provided with heat-resistant rubber, the bearing steel part 5 is contacted and provided on the heat-resistant rubber, and the electromagnetic heating coil 3 matches the position of the bearing steel part 5 on the display arc plate 233, one end of the bending rod 262 is embedded in the lower end of the display arc plate 233 and is movably connected, and the bending rod 262 is used to make the display arc The plate 233 rotates, causing the bearing steel part 5 to fall off. The bearing steel part 5 on the arc plate 233 can be heated by the electromagnetic heating coil 3. When the rotating disk 21 rotates, the transmission shaft 231 is also driven to rotate, causing the second gear 232 to roll along the inner gear ring 24, so that the bearing steel part 5 can be driven to rotate by the arc plate 233, thereby rotating and heating the bearing steel part 5. At the same time, the bent rod 262 is also driven to rotate by the arc plate 233. When the rotating disk 21 moves downward, the bent rod 262 pushes the arc plate 233 to rotate and tilt, causing the bearing steel part 5 to fall off.

[0042] like Figure 7As shown, the lower end of the arc plate 233 is fixedly connected to a support column 234, and the lower end of the support column 234 is embedded with a movably connected ball 235, and the ball 235 is in contact with the upper end of the rotating disk 21.

The receiving net 426 is fixedly connected to the first fixing ring 424 and the second fixing ring 425. The position of the receiving net 426 matches the position of the arc plate 233. The height of the receiving net 426 can be controlled by extending and retracting the second electric telescopic rod 422, so that the contact between the bearing steel part 5 and the quenching liquid can be controlled. The bearing steel part 5 falling from the arc plate 233 will fall on the receiving net 426. The receiving net 426 is made to fall by the second electric telescopic rod 422, so that the bearing steel part 5 can be immersed in the quenching liquid and can be quickly cooled. The buffering of the receiving net 426 can reduce the splashing of the quenching liquid. The separation of the connecting strip 423 can prevent the bearing steel part 5 from rolling and colliding on the receiving net 426.

During heating, the second motor 224 is started, so that the arc plates 233 rotate slowly while rotating with the rotating disk 21, so that the bearing steel parts 5 can rotate and heat up. After heating, the first electric telescopic rod 252 is retracted. The contraction causes the arc plate 233 to move downward. Since the telescopic sleeve 261 cannot be further extended, the bent rod 262 will lift the arc plate 233, causing the arc plate 233 to tilt toward the direction of the cooling component 4, so that the bearing steel part 5 can slide onto the receiving net 426, and then the bearing steel part 5 is immersed in the quenching liquid through the second electric telescopic rod 422. The present invention realizes the synchronous loading and unloading of multiple groups of bearing steel parts 5, which can effectively improve the efficiency of surface hardening heat treatment. The rotational heating can improve the uniformity of heating of the bearing steel parts 5, thereby improving the surface hardening quality of the bearing steel parts 5. The buffering of the receiving net 426 can reduce the splashing of the quenching liquid and reduce waste.
