Four stations 11, 12, 13, and 14 are uniformly and spacedly arranged on the four-station rotating disc 1 in a circumferential direction. A lifting cylinder 10 for fixing a live wrench 20 is arranged on each station 11, 12, 13, and 14. The first station 11 is a feeding station. The live wrench 20 is placed into the first station 11 by the automatic mechanical hand. The second station 12 is a positioning station. The lifting cylinder 10 is lowered to fix the live wrench 20. The third station 13 is a handle station. A fifth station 4 is arranged on the workbench 2 corresponding to the third station 13. A rubber handle 30 is conveyed to the fifth station 4 by the conveying belt 3. A first cylinder 40 is arranged on the fifth station 4 to fix the rubber handle 30. A second cylinder 5 is arranged on the workbench 2 to push the fifth station 4 to move forward and backward and to put the rubber handle 30 into the live wrench 20. The fourth station 14 is a discharging station. The lifting cylinder 10 is raised. The live wrench 20 with the handle is taken out by the automatic mechanical hand.

[0022] Specifically, two positioning grooves 15 for two live wrenches 20 are arranged side by side on each station 11, 12, 13, and 14 of the four-station rotating disc 1. The two live wrenches 20 are placed in the corresponding positioning grooves 15. The handle of the live wrench 20 extends out of the station. Two lifting cylinders 10 are arranged on each station 11, 12, 13, and 14, respectively, above the corresponding positioning grooves 15. A track 21 is arranged on the workbench 2 for the fifth station 4 to move forward and backward. Two positioning points for two rubber handles 30 are arranged side by side on the fifth station 4. The rubber handle 30 is positioned on the fifth station 4 corresponding to the handle of the live wrench 20 on the third station 13.

[0023] The process flow of the fifth station 4 for sleeving the handle 30 is shown in the figure, and specifically comprises the following steps: (a) the handle 30 at the terminal end of the conveying belt 3 enters the fifth station 4, and the first cylinder 40 is lowered to fix the handle 30; (b) the second cylinder 5 pushes the fifth station 4 to move forward to align with the third station 13, and the handle 30 is sleeved into the handle part of the spanner 20; (c) the lifting cylinder 10 is raised to loosen the spanner 10 with the sleeved handle 30; (d) the first cylinder 40 and the second cylinder 5 are automatically returned to the original position, the fifth station 4 is returned to the original position, and the handle 30 on the conveying belt 3 enters the fifth station 4, and the above steps are repeated. Figure 3

[0024] The conveying belt 3 is provided on the left and right sides of the fifth station 4, and the handle 30 is sent into the conveying belt 3 through a circular vibrating disc and an infrared sensor. The terminal end of the conveying belt 3 corresponds to the positioning point on the fifth station 4.
