[0024] Embodiment 1, See also Figure 1 , Figure 2 , Figure 3 and Fig. 9, an embodiment provided by the present invention: a nut turning device with a surface strengthening treatment function, comprising a nut turning device body 1, a partition 6 is installed inside the nut turning device body 1, and the partition 6 is used to separate the nut turning device body 1 from left to right into a surface treatment area and a turning processing area, three groups of partitions 2 7 are evenly arranged inside the surface treatment area, and the partition 2 7 is used to separate the surface treatment area from left to right into a second cleaning tank, an electroplating tank, a phosphating treatment tank and a first cleaning tank, a cathode 8 and an anode 9 are installed on the bottom wall of the electroplating tank, and the anode 9 is located on one side of the cathode 8, a fan 10 is installed on one inner wall of the surface treatment area, and the fan 10 is located above the second cleaning tank, a moving path 12 is installed on the top wall of the surface treatment area, a moving component is installed inside the moving path 12, and a mechanical arm 11 is installed on the output end of the moving component, and a camera 2 39 is installed on the top wall of the surface treatment area, and the camera 2 39 is located above the electroplating tank; The moving assembly includes a control motor 13 and a guide rod 15 installed inside the moving track 12. The guide rod 15 is located above the control motor 13. A lead screw 14 is installed at the output end of the control motor 13. The outer surfaces of the lead screw 14 and the control motor 13 are sleeved with a connecting piece, and the bottom of the connecting piece is connected to the top of the robot arm 11.

[0025] Furthermore, the nut turning device is composed of a surface treatment part and a turning processing part. First, the nut is turned. After the processing is completed, the robot arm 11 clamps the nut and places the nut in the first cleaning tank. The oil, rust and other impurities on the surface of the nut are cleaned with a chemical cleaning agent. Then, the robot arm 11 clamps the nut into the phosphating treatment tank, immerses the nut in a solution containing phosphate, and stands for a period of time. A dense phosphating film is formed on the surface of the nut through a chemical reaction. Then, the robot arm 11 sends the nut into the electroplating tank, and the zinc ions in the electroplating tank are reduced and deposited on the surface of the nut through the action of electric current, forming a phosphating film on the surface of the nut. Uniform zinc plating, camera 2 39 will monitor the entire process of surface strengthening treatment in real time. After the electroplating is completed, the nut is moved to the second cleaning tank and the electrolyte on the nut is cleaned with clean water. Then the robot arm 11 clamps the nut out of the second cleaning tank and quickly dries it under the action of the fan 10 to remove the residual moisture on the surface of the nut. By performing surface strengthening treatment on the nut, the corrosion resistance and aesthetics of the nut can be significantly improved. In actual use, the shot peening process can also be used to achieve surface strengthening of the nut. The steel shot or ceramic shot is highly impacted on the surface of the nut to form a compressive residual stress layer on the surface of the nut to improve the fatigue resistance of the nut. In order to enable the robot arm 11 to move freely within the entire range of the surface treatment area, a moving component is provided to achieve this function. According to the movement requirements of the robot arm 11, the main controller 2 controls the operation of the control motor 13, thereby driving the screw 14 to rotate, so that the robot arm 11 moves along the direction of the guide rod 15, so that the robot arm 11 can clamp the nut and perform corresponding treatments in the first cleaning tank, phosphating treatment, electroplating tank and second cleaning tank in sequence, which helps the nut to achieve surface strengthening treatment without human interference.

[0027] Furthermore, during the turning process, according to the size of the nut to be processed and the processing requirements, automatic tool change can be performed. Different types of turning tools 26 are placed in the storage slot of the tool holder 25. When the tool needs to be changed, the small motor 27 runs to drive the tool holder 25 to rotate.
