The guide seat 5 is arranged above the pin guide seat 3 and is tightly fitted and connected. The pressing plate 6 is arranged above the guide seat 5 and maintains a predetermined spacing. The upper part of the pressing plate 6 is used to connect the press machine.

[0018] The pin guide seat 3 has a vertically penetrating press-fitting hole 32, one side of the press-fitting hole 32 has a pin sorting groove 31, the press-fitting hole 32 is connected to one end of the pin sorting groove 31, and the other end of the pin sorting groove 31 is connected to the guide groove of the vibration plate, so that the pins automatically enter the press-fitting hole 32 after sorting. The pressing plate 6 is provided with a pressing rod 61 facing the press-fitting hole 32, which is used to axially push the pins to realize the press-fitting action.

[0019] The workpiece guide seat 4 is arranged on the frame 1 on one side of the press-fitting base 2. A workpiece sorting groove 51 is provided between the workpiece guide seat 5 and the press-fitting base 2. The other end of the workpiece sorting groove 51 is connected to the guide groove of the vibration plate, so that the workpieces enter the workpiece sorting groove 51 in sequence after being sorted. A workpiece insertion groove 21 is provided between the pin guide seat 3 and the press-fitting base 2. The workpiece insertion groove 21 is connected to the press-fitting hole 32 so that the pin can be press-fitted into the hole on the workpiece after the workpiece is inserted.

[0020] The frame 1 is provided with a push-in mechanism facing the workpiece insertion slot 21, which is used to push the workpiece into the workpiece insertion slot 21.
