In the actual implementation process, when the cylinder head is plated, the electric push rod 3 is started so that its output end drives the mounting block 4 to move downward, thereby making the spray gun 5 move synchronously. By setting the pulling plate 11, the position of the clamping plate 10 remains unchanged, so that the sliding block 8 slides inside the sliding groove 6, so that the elastic rod 7 is compressed, and the arc cleaning plate 9 is driven to move upward synchronously. By setting the pin shaft, the arc cleaning plate 9 moves in contact with the surface of the spray gun 5 when moving upward, so that the discharge port of the spray gun 5 leaks out, thereby coating the cylinder head through the spray gun 5. After the cover coating is completed, the spray gun 5 is reset by the electric push rod 3, and the sliding block 8 is reset by the elastic force of the elastic rod 7, driving the arc cleaning plate 9 to reset synchronously, so that the arc cleaning plate 9 slides on the surface of the spray gun 5 to clean the surface of the spray gun 5, and the elastic force of the elastic connecting rod 12 is used to shrink one side of the arc cleaning plate 9, so that one side of the arc cleaning plate 9 is fitted with the discharge port of the spray gun 5 to clean the discharge port of the spray gun 5, and the arc cleaning plate 9 is reset so that the arc cleaning plate 9 is wrapped around the surface of the spray gun 5 to protect the spray gun 5.

[0027] Optionally, the driving mechanism includes a driving motor 13 fixedly connected to the inside of the working box 1, a threaded rod 14 fixedly connected to the output end of the driving motor 13, a moving block 15 threadedly connected to the surface of the threaded rod 14, the threaded rod 14 is rotatably connected to the inside of the working box 1 through a bearing seat, and the mounting plate 2 is fixedly connected to the moving block 15. In the actual implementation process, by starting the driving motor 13, the output end thereof drives the threaded rod 14 to rotate inside the working box 1, driving the moving block 15 and the mounting plate 2 to slide inside the working box 1, so that the spray gun 5 can coat different positions of the cylinder head, making the cylinder head more comprehensive when coating.

[0028] Optionally, two corresponding observation windows 16 are symmetrically installed on one side of the working box 1, an electric heating plate 17 is fixedly connected to the middle of one side of the working box 1, a power supply electrically connected to the electric heating plate 17 through a wire is fixedly connected to the surface of the working box 1, and support legs are fixedly connected to the four corners of the lower surface of the working box 1. In the actual implementation process, the setting of the observation window 16 makes it convenient for the staff to observe the operation inside the working box 1 more conveniently. Through the setting of the electric heating plate 17, after the cylinder head is plated, the cylinder head is moved out of the working box 1 through the components of the rotating mechanism, and the cylinder head is heated and dried, thereby improving the coating efficiency of the cylinder head. Through the setting of the working box 1, the cylinder head is brought into the interior of the working box 1 through the rotating mechanism, thereby avoiding the splashing of the coating raw material when the cylinder head is plated.

[0029] Optionally, the rotating mechanism includes a hollow plate 18 slidably connected to the working box 1, and driving tooth plates 19 are fixedly connected to both sides of the lower surface of the hollow plate 18. The surface of the driving tooth plate 19 is meshed with a driving gear 20 rotatably connected to the inside of the working box 1. The surfaces of the two driving gears 20 are commonly fixedly connected to a rotating rod 25 rotatably connected to the working box 1. One end of the rotating rod 25 is fixedly connected to a servo motor 26 whose output end is fixedly connected to the rotating rod 25. The servo motor 26 is fixedly connected to the inside of the working box 1. The two driving tooth plates 19 are slidably connected to the working box 1, and the hollow plate 18 corresponds to the electric heating plate 17. In the actual implementation process, the cylinder head is installed inside the hollow plate 18, and the servo motor 26 is started so that its output end drives the rotating rod 25 to rotate, thereby rotating the two driving gears 20, driving the driving tooth plate 19 to slide inside the working box 1, and driving the hollow plate 18 to move to the inside of the working box 1, so that the spray gun 5 coats the cylinder head.

[0030] Optionally, the rotating mechanism further includes an elastic block 21 rotatably connected to a side wall of the hollow plate 18, a rotating motor 22 is fixedly connected to the inside of the hollow plate 18, a rotating rod 23 is fixedly connected to the output end of the rotating motor 22, and a mounting plate 24 is fixedly connected to the opposite side of the rotating rod 23 and the elastic block 21. In the actual implementation process, the cylinder head is clamped by two mounting plates 24 so that the cylinder head is installed inside the hollow plate 18. Through the setting of the elastic block 21, the two mounting plates 24 can clamp cylinder heads of different lengths. When the spray gun 5 coats the cylinder head, the rotating motor 22 is started so that its output end drives the rotating rod 23 to rotate, thereby rotating the corresponding mounting plate 24 and driving the cylinder head to rotate, so that the cylinder head is more uniform during coating, avoiding manual flipping of the cylinder head, and through the setting of the elastic block 21 and another mounting plate 24, the cylinder head is more stable when flipping.

[0031] Optionally, the rotating rod 23 is rotatably connected to the hollow plate 18, the two mounting plates 24 are rotatably connected to the inside of the hollow plate 18, and the upper surface of the moving block 15 is fixedly connected to a limit rod slidably connected to the top wall of the working box 1 in a path array.
