[0027] A first position sensing element 5 is provided at the first side thrust device 2 , and a second position sensing element 6 and a third position sensing element 7 are provided at the press-fitting station.
[0028] When press-fitting the sprocket, each gear box is placed on the conveyor line 1, and the sprocket is pre-mounted on the sprocket shaft of the gear box. The conveyor line 1 runs to transport the gear box to the first side pusher 2. When the first position sensing element 5 senses the gear box, the conveyor line 1 stops running; the first side pusher 2 is activated to push the gear box to the press-fitting station. When the second position sensing element 6 senses the gear box, the first side pusher 2 stops and then resets; the press-fitting device 4 presses down the sprocket. When the third position sensing element 7 senses the sprocket, it means that the sprocket is assembled in place. The press-fitting device 4 stops pressing and then resets; the second side pusher 3 is activated to push the gear box to the conveyor line 1. When the first position sensing element 5 senses the gear box, the second side pusher 3 stops and then resets, and the conveyor line 1 runs to transport the gear box to the next process.
[0029] In addition, when the second side pusher 3 moves to push the gear box onto the conveyor line 1, the first position sensing element 5 can not only sense the gear box, but also sense the position of the sprocket, thereby detecting whether the sprocket is assembled in place, further ensuring the assembly quality.
