All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-5 An embodiment of this utility model provides: a stress monitoring and control device for heat treatment of aluminum alloy wheel hub, including a base plate 1 and a treatment box 2. The treatment box 2 is provided at the middle position of the top of the base plate 1, and telescopic rods 14 are provided at the middle positions of both sides of the base plate 1. A support platform 3 is provided between the output ends of the telescopic rods 14, and a fixed rod 11 and a movable rod 9 are respectively provided at the middle positions of the two ends of the bottom of the support platform 3. A telescopic rod 4 is provided at the middle position of the top of the support platform 3 near the end of the movable rod 9, and a connecting block 5 is provided at the output end of the telescopic rod 4. The top of the movable rod 9 is connected to the bottom of the connecting block 5 through a movable groove 18.

[0022] In use, the hub can be placed on the transmission rod inside the fixed rod 11, and the telescopic rod 14 can drive the connecting block 5 and the moving rod 9 to move together, so that the snap ring 12 inside the fixed rod 11 and the moving rod 9 can clamp it. During heat treatment, the drive mechanism outside the fixed rod 11 can be started, so that it drives the transmission rod to rotate, and the transmission rod drives the hub to rotate together. Then the telescopic rod 24 drives the support platform 3 to move down, so that heat treatment can be carried out evenly.

[0023] Both the moving rod 9 and the fixed rod 11 are provided with a snap ring 12 at the bottom of their inner sides, and both sides of the inner surface of the snap ring 12 are provided with a deformation sensor 24 at the middle position, and the inner surface of the snap ring 12 between the deformation sensors 24 is provided with a pressure sensor 23. Both the fixed rod 11 and the moving rod 9 are provided with a temperature sensor 6.

[0024] In use, the temperature sensor 6 inside the fixed rod 11 and the moving rod 9 can monitor their temperature to prevent excessive temperature differences during heat treatment. The pressure sensor 23 and deformation sensor 24 inside the snap ring 12 can monitor the stress changes of the wheel hub during heat treatment. The stress changes can be monitored and adjusted in conjunction with the spray block 10 for spray cooling circulation.

[0025] A moving groove 18 is provided at the middle position of one end of the support platform 3 corresponding to the moving rod 9. A mist-absorbing block 7 is provided at the top of the moving groove 18 on both sides of the moving rod 9. A mist-absorbing pipe is provided at the middle position of the outer side of each mist-absorbing block 7, connecting to an external mist-absorbing box. Suction holes are evenly distributed on the inner side of each mist-absorbing block 7. A screw groove 8 is provided in the support platform 3 at the bottom of each mist-absorbing block 7, and a screw 21 is provided in each screw groove 8. A threaded block 25 is threadedly connected to each screw 21. An L-shaped brush 17 is provided on the side of the threaded block 25 closest to the moving groove 18, and the bristles of the L-shaped brush 17 are connected to the suction... The fog blocks 7 are attached together. The support platform 3 at one end of the screw groove 8 is provided with a connecting groove 19. The screws 21 in the screw groove 8 all extend into the connecting groove 19 through bearings. The screws 21 in the connecting groove 19 are all optical shafts. The optical shafts of the screws 21 are all provided with pulleys 20. The pulleys 20 are connected to each other by belts. The support platform 3 is provided with a motor groove at the position of the screw 21 on one side away from the connecting groove 19. The motor groove of the support platform 3 is provided with a motor 22. The output end of the motor 22 extends into the screw groove 8 through bearings and couplings and is connected to the screw 21.

[0026] In use, the mist-absorbing block 7, mist-absorbing pipe, and mist-absorbing box can absorb the mist generated by the spray cooling, preventing it from affecting normal observation. Then, the motor 22 can be started to drive the lead screw 21 connected to its shaft to rotate, which in turn drives the pulley 20 on the optical shaft to rotate. The pulleys 20 are connected by a belt and rotate, which drives the lead screws 21 on both sides to rotate synchronously. The lead screw 21 drives the L-shaped brush 17 on one side of the threaded block 25 to move and clean the mist-absorbing block 7, preventing the suction holes from being blocked and affecting its mist-absorbing effect.

[0027] The bottom of the support platform 3 outside the fixed rod 11 and the moving rod 9 is provided with a spray block 10, and the inner side and bottom of the spray block 10 are provided with nozzles facing the middle, and the middle position of the top of one side of the spray block 10 is provided with a liquid inlet pipe. The upper sides of both sides of the processing box 2 are provided with heating plates 13, and the bottom of the processing box 2 is provided with a filter plate 15, and the middle position of the bottom of the processing box 2 is provided with a circulation pipe 16.

[0028] In use, the heating plate 13 can heat the interior, and then the liquid inlet pipe connected to the liquid storage tank can send the liquid to the spray block 10 to spray and cool the hub. The sprayed liquid dripping down is filtered through the filter plate 15, and then enters the external pump body and heat exchanger through the circulation pipe 16. It is then discharged from the heat exchanger and enters the liquid storage tank to achieve circulating water delivery, which can reduce stress concentration caused by uneven cooling.

[0029] In this embodiment, the hub is placed on the transmission rod inside the fixed rod 11, and the telescopic rod 4 moves the connecting block 5 and the moving rod 9 together. This allows the retaining ring 12 inside the fixed rod 11 and the moving rod 9 to clamp the hub. During heat treatment, the drive mechanism outside the fixed rod 11 is activated, causing the transmission rod to rotate, which in turn rotates the hub. Then, the telescopic rod 14 moves the support platform 3 downwards, activating the heating plate 13 to heat the interior evenly. During heat treatment, the temperature sensor 6 inside the fixed rod 11 and the moving rod 9 monitors the temperature to prevent excessive temperature variations. The pressure sensor 23 and deformation sensor 24 inside the retaining ring 12 monitor the stress changes of the hub during heat treatment, allowing for stress monitoring and coordinating with the liquid storage tank. The connected inlet pipe delivers liquid to the spray block 10, which sprays and cools the hub. The sprayed liquid is filtered through the filter plate 15, then enters the external pump body and heat exchanger through the circulation pipe 16, and is discharged from the heat exchanger into the storage tank, realizing water circulation. This reduces stress concentration caused by uneven cooling. When the spray water mist is generated, the mist-absorbing block 7, mist-absorbing pipe, and mist-absorbing box can absorb the mist generated by the spray cooling, preventing it from affecting normal observation. Then, the motor 22 can be started to drive the lead screw 21 connected to its shaft to rotate, which in turn drives the pulley 20 on the optical shaft to rotate. The pulleys 20 are connected by a belt and rotate, which drives the lead screws 21 on both sides to rotate synchronously. The lead screws 21 drive the L-shaped brush 17 on one side of the threaded block 25 to move and clean the mist-absorbing block 7, preventing the suction holes from being blocked and affecting its mist absorption effect.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
