The power output end of the pad drive device 17 is connected to the pad 16. The pad 16 is located on the lower side of the small tire membrane 2. The signal output ends of the first sensor 3 and the second sensor 6, the bending assembly lifting drive device 9, the bending knife horizontal drive device 19, the supporting cylinder 12, the small tire mold lifting drive device 14, and the control ends of the pad drive device 17 are all connected to a controller.

[0022] Furthermore, a locking pin cylinder 7 is provided on the base, a locking pin 8 is connected to the power output end of the locking pin cylinder 7, and a locking pin hole that cooperates with the locking pin 8 is provided in the lifting seat 22.

[0023] Furthermore, the lifting seat 22 is set on the base through the first linear guide rail 10.

[0024] Furthermore, the bending knife 18 is arranged on the lifting seat 22 through a second linear guide rail 20.

[0025] Furthermore, a guide post 15 is connected to the lower side of the small fetal membrane 2, and the guide post 15 passes downward through the base.

[0026] Furthermore, a waist-shaped hole is provided on the lifting seat 22, and the bending knife 18 is connected to the lifting seat through the waist-shaped hole and screws.

[0027] Furthermore, the controller is a PLC.

[0028] Furthermore, the pad driving device 17 is a cylinder.

[0029] Specifically, the first sensor 3, the second sensor 6, the bending assembly lifting drive device 9, the bending knife horizontal drive device 19, the supporting cylinder 12, the small tire mold lifting drive device 14, the pad drive device 17, etc. in this embodiment all adopt well-known solutions in the prior art, which are well understood by those skilled in the art and will not be repeated here.

[0030] The working principle of this embodiment is as follows:

[0031] Put the loudspeaker mesh shield 1 into the cavity of the small tire mold 2, and the first sensor 3 on the small tire mold 2 senses it. The worker then puts the car door panel 4 into the cavity of the lower mold 5, triggering the second sensor 6. The PLC sends a command to the lock pin cylinder 7 to drive the lock pin 8 to retreat and unlock the lifting seat 22, and then the lifting cylinder 9 drives the bending mechanism to move downward along the first linear guide rail 10. At this time, the spring pressure block 11 on the bending mechanism begins to press the car door panel 4. After moving downward to a specific distance, the support cylinder 12 drives the top block 21 to move up and press the lower side of the lifting seat 22 for limiting, and the bending mechanism stops moving downward. Then the loudspeaker mesh shield 1 and the small tire membrane 2 are pushed upward along the guide column 15 by the small tire mold lifting drive device 14. The clamping pin 23 on the speaker grid shield 1 enters the metal speaker grid shield clamping pin mounting hole on the automobile door panel 4, and then the pad driving device 17 drives the pad 16 to move to the lower side of the small tire membrane 2 to pad the small tire mold 2. The bending knife 18 is pushed by the bending cylinder 19 to bend the clamping pin 23 of the speaker grid shield 1 90 degrees along the second linear guide rail 20. After the 90-degree bending is completed, the supporting cylinder 12 drives the top block 21 to start moving downward, releasing the downward pressure space of the lifting seat 22, and the bending assembly lifting drive device 9 drives the bending mechanism to continue to move downward along the first linear guide rail 10 until the bending knife 18 presses the clamping pin 23 on the speaker grid shield 1, and finally all parts return to their initial positions.

[0032] The utility model is composed of a loudspeaker grid shield, a car door panel placement part, a loudspeaker grid shield installation hole automatic docking part, a car door panel pressing and positioning part, a loudspeaker grid shield foot bending and pressing part, etc.

[0033] Advantages of this utility model:

[0034] 1. The tooling can accurately position the speaker grid shield 1 and automatically connect its clamping feet 23 to the speaker grid shield clamping foot mounting holes on the car door panel, and then automatically perform the bending and tightening action of the clamping feet 23, eliminating the need to manually install the clamping feet 23 of the speaker grid shield 1 into the speaker grid shield mounting holes on the car door panel 4, thereby reducing manual labor intensity, speeding up production, reducing scrap rate, improving production efficiency and production stability, and saving costs.

[0035] 2. This tooling is highly adaptable and flexible, allowing the forward and backward movement distance of the bending blade 18 and the bending and tightening effect to be adjusted according to actual conditions. The position of the bending blade 18 can be adjusted through the waist-shaped hole. While the bending blade 18 completes the 90° bend of the clamping foot 23, it can also contour the clamping foot 23 to the shape of the vehicle door panel B surface, firmly adhering to the vehicle door panel 4, and preventing the speaker grille from loosening.
