First, the two tooth hook mechanism 6 feeds the two tooth hooks 24 one by one, and The material picking action is performed by the two-tooth hook material picking mechanism on the two-tooth hook mechanism 5. At the same time, a rivet feeding mechanism is also provided here. After the two-tooth hooks 24 are placed, the flat head rivets 25 are placed in cooperation, and then the riveting action is completed by the two-tooth hook riveting mechanism. Finally, the installed inner rail 22 is removed from the right side of the material support and conveying mechanism 10, thereby completing the automatic installation of the shift fork 23 and the two-tooth hooks 24 on the inner rail 22.

[0050] During operation, after the two-tooth hook guide rack 60 transports the two-tooth hook 24 to the rotary material receiving platform 61, the clamping tooth assembly 63 clamps and limits the rotary material receiving platform 61, and then rotates through the rotating base 62 to cooperate with the clamping action of the two-tooth hook clamp assembly 50. The clamp moving assembly 51 drives the two-tooth hook clamp assembly 50 to take the material and place it in the corresponding work station. The rivet loading mechanism on the two-tooth hook mechanism 5 will transport the flat head rivet 25 to the position of the two-tooth hook duckbill clamp 52, and then the two-tooth hook pressing assembly 53 can perform the riveting action on the two-tooth hook 24.
