[0026] A terminal is placed on the terminal delivery limit block 2, and the terminal delivery cylinder 1 controls the terminal delivery push rod 3 to push the terminal into the terminal clamp 9. The crimping support seat 8 moves horizontally to the rear of the threading vertical plate 4, and the wire is inserted into the threading hole 7. The upper and lower threading cylinders 5 and the left and right threading cylinders 6 clamp the wire up and down and left and right respectively. After fixing the position of the wire, the crimping support seat 8 is close to the wire so that the terminal is inserted into the wire. The crimping motor 10 controls the rotation of the crimping screw rod 11, and the crimping nut 12 drives the crimping push plate 13 to push the terminal clamp 9, so that the terminal clamp 9 rivets the terminal onto the wire, and then the terminal clamp 9 is released and leaves the wire, and the terminal remains on the wire and can be taken away.

[0027] The driving ends of the upper and lower threading cylinders 5 are connected to the upper clamping jaw 14 and the lower clamping jaw 15, and the driving ends of the left and right threading cylinders 6 are connected to the insertion block 16. The insertion block 16 is inserted into the gap formed between the upper clamping jaw 14 and the lower clamping jaw 15.
