[0068] When the embodiment of the present application is used:

[0069] Preparation work

[0070] Check the appearance of the processing box 1 to ensure that there is no damage or deformation, and the box structure made of high-strength steel is stable. Confirm that the infrared sensor 2 is firmly installed and tightly connected with the inner wall of the processing box 1 through bolts, and check whether its working state is normal. The sensor can be observed to accurately detect the signal through operations such as placing a simulated rim.

[0071] Check the connection of the support frame 4, the baffle 10, the driving frame 9, the hinged frame 8, the hinged seat 5, the air cylinder 6 and the push rod 7, etc. to ensure that the connection is firm and the movable parts can rotate or move flexibly. For example, manually push the driving frame 9 to check whether it rotates smoothly under the connection of the hinged frame 8 and the hinged seat 5, whether the air cylinder 6 can normally extend and retract, and whether the push rod 7 is in good contact with the driving frame 9.

[0072] Check the driving box 11, the positioning box 20 and their internal components, such as the support rod 21, the support spring 25, the adapter frame 24, the reinforcing spring 23 and the sensing block 22, etc. Ensure that the support rod 21 is well matched with the positioning hole of the positioning box 20, the support spring 25 and the reinforcing spring 23 are not damaged and have normal elasticity, and the sensing block 22 is firmly installed and can normally sense signals.

[0073] Check the limiting frame 12, the bearing table 14, the transmission frame 13, the driving gear 16, the auxiliary gear 19, the gear belt 18, the servo motor 15 and the rotating shaft 17, etc. transmission components. Ensure that the driving gear 16 and the auxiliary gear 19 are well engaged with the gear belt 18, the gear belt 18 has moderate tension (which can be adjusted by the tensioning device), the servo motor 15 is firmly connected with the rotating shaft 17, and the coupling has no looseness.

[0074] Check whether the connection cable between the controller 3 and the infrared sensor 2 is intact, whether the preset program in the controller 3 is correct, and whether the controller 3 can normally receive and process the signals of the infrared sensor 2.

[0075] Rim loading: Start the air cylinder 6, which drives the push rod 7 to extend upwards, pushing the drive frame 9 to rotate around the hinge frame 8 and the connecting point of the hinge seat 5, causing the baffle 10 to open, exposing the internal space of the processing machine box 1. Carefully place the rim to be processed on the bearing table 14, trying to align the center of the rim with the desired position for processing. Start the air cylinder 6 again to retract the push rod 7, causing the drive frame 9 to rotate in the opposite direction and close the baffle 10, sealing the rim inside the processing machine box 1 and providing protection.

[0076] Rim positioning: The infrared sensor 2 starts working, real-time detecting the position and state of the rim in the processing machine box 1 and transmitting the detected signals to the controller 3 through the cable. The controller 3 judges whether the position of the rim is accurate according to the signals received from the infrared sensor 2. If the position is not accurate, the controller 3 sends a command to control the servo motor 15 to start. The output end of the servo motor 15 drives the rotating shaft 17 to rotate through the coupling, and the rotating shaft 17 drives the driving gear 16 to rotate. The driving gear 16 meshes with the gear belt 18, driving the gear belt 18 to move, which in turn drives the auxiliary gear 19 to rotate. Since the bottom end of the bearing table 14 is connected to the gear belt 18 through the transmission frame 13, the movement of the gear belt 18 drives the bearing table 14 to move within the range defined by the limiting frame 12, thereby adjusting the position of the rim until the infrared sensor 2 detects that the position of the rim meets the processing requirements, and the controller 3 controls the servo motor 15 to stop rotating. At the same time, the support rod 21 in the positioning box 20 is tightly pressed against the rim under the elastic force of the support spring 25, providing stable support for the rim. The reinforcing spring 23 and the sensing block 22 further enhance the stability of the system, and the sensing block 22 real-time senses the force and displacement of the rim during processing and feeds back the signals to the controller 3 for real-time monitoring and necessary adjustments.

[0077] Rim processing: After the rim positioning is completed, the external processing equipment (not described in detail in this tool structure, but actually exists during processing) starts processing the rim. During processing, the infrared sensor 2 continuously monitors the state of the rim, and the sensing block 22 also real-time feeds back the force and displacement information of the rim to the controller 3. If the controller 3 judges that the rim has abnormal displacement or excessive force according to the received information, it will promptly issue an instruction to control the servo motor 15 to fine-tune the position of the bearing table 14, or through other means (such as adjusting the parameters of the processing equipment) to ensure the smooth progress of processing and the processing accuracy of the rim.

[0078] Finish and unloading: when the rim is finished, the external processing equipment stops working. Start the cylinder 6, make the push rod 7 extend, and open the baffle 10. Carefully take the finished rim from the supporting table 14, and complete the unloading operation. Close the cylinder 6, make the push rod 7 retract, and close the baffle 10, ready for the next processing.

[0079] Equipment maintenance and maintenance: regularly clean the metal chips, dust and other sundries inside the processing box 1, and keep the equipment clean. Check the connection of each part, such as whether the bolts are loose, and tighten the loose bolts in time. Check the detection accuracy of the infrared sensor 2, and calibrate if necessary. Check the elasticity of the supporting spring 25 and the reinforcing spring 23, and replace them in time if the elasticity is found to be decreased or damaged. Check the wear of the gear belt 18, replace it in time if the wear is serious, and adjust the tension of the gear belt 18. Regularly maintain the power components such as the servo motor 15, such as checking the heat dissipation and lubrication of the motor.
