At least three upper tooling limit columns 4 are provided at the corners of the upper tooling 1. The upper tooling limit columns 4 are arranged in a triangular shape. The triangle has stability, making the connection between the upper tooling 1 and the lower tooling 2 more stable.
[0027] A lower tooling limit column 5 is provided on the end face of the lower tooling 2 corresponding to the guide column. A product positioning reference seat 6 is also provided on the end face of the lower tooling 2 for placing the steering wheel 3. The steering wheel 3 is placed on the product positioning reference seat 6. A lower rivet limit column 7 for riveting is provided around the product positioning reference seat 6. An upper rivet limit column 8 is provided on the end face of the upper tooling 1 corresponding to the lower rivet limit column 7. After the rivet is placed, force is applied to the lower rivet limit column 7 through the upper rivet limit column 8 to install the rivet on the steering wheel 3.
[0028] The lower tooling 2 is electrically connected to a warning device 9, through which the riveting situation is displayed. The upper tooling 1 is provided with a connecting wire electrically connected to the warning device 9. The connecting wire contacts the lower tooling 2 to form a path for supplying power to the warning device 9. The warning device 9 is electrically connected to a power line 10.
[0029] The warning device 9 includes a power light 11, a warning light 12 and a buzzer 13. The number of the warning lights 12 is consistent with the number of the lower rivet limit columns 7, and the corresponding lower rivet limit columns 7 are marked with numbers on the warning lights 12. The riveting status of the corresponding lower rivet limit columns 7 can be judged by the lighting status of the warning lights 12 with corresponding numbers.
[0030] The connecting wires include a warning light connecting wire 14, an upper buzzer connecting wire 15 and a lower buzzer connecting wire 16. The warning light connecting wire 14 is placed on the upper rivet column, and the warning light connecting wire 14 and the corresponding lower rivet column form a path for supplying power to the warning light 12. When the riveting work is carried out normally, the four paths are all energized normally and the warning light 12 is on.
[0031] The upper connecting wire 15 of the buzzer is placed on the upper tooling 1, and the lower connecting wire 16 of the buzzer is placed on the lower tooling 2. The upper connecting wire 15 of the buzzer and the lower connecting wire 16 of the buzzer form a path for powering the buzzer 13. A connecting hole 17 is provided on the side wall of the lower tooling 2, and a mounting hole 18 is provided on the side wall of the upper tooling 1.
