[0043] Embodiment 1

[0044] The device described in Device Example 1 is adopted.

[0045] First, place the work box 1 in the surface treatment area of the special-shaped part, then place the special-shaped part between the clamping blocks 7. Subsequently, start the first motor 2 to drive the rotation of the bidirectional lead screw 3, causing the first moving frames 4 to move closer to each other, driving the rotary guide frames 6 to move closer to each other, so that the clamping blocks 7 contact the special-shaped part. Through the action of the first spring 8, the anti-slip pads on the clamping blocks 7 closely adhere to the special-shaped part to clamp the special-shaped part. After that, introduce penetrant into the liquid spraying pipe 10, and then move the second moving frame 9 through the handle, so that the liquid spraying pipe 10 moves above the special-shaped part, and spray the penetrant onto the special-shaped part through the nozzle. After one side of the special-shaped part is sprayed, start the second motor 5 to drive the rotary guide frame 6 to rotate, so that the special-shaped part is flipped, and then spray the penetrant onto the other side of the special-shaped part. When it is necessary to remove and recycle the excess penetrant on the surface of the special-shaped part, start the cylinder 14 to push the fixed guide frame 15 to move downward, so that the cleaning and filtering frame 16 moves downward. Then start the third motor 11 to drive the rotation of the rotary lead screw 12, so that the third moving frame 13 moves to the right. When the cleaning and filtering frame 16 moves to the position of the special-shaped part, through the action of the second spring 17, the cleaning rollers on the cleaning and filtering frame 16 closely adhere to the surface of the special-shaped part and move, removing the excess penetrant on the surface of the special-shaped part, and making the excess penetrant fall into the work box 1 for recycling, thus playing the role of being able to fit the contour of the surface of the special-shaped part, removing the excess penetrant on the surface of the special-shaped part, and improving the removal efficiency. While the fixed guide frame 15 moves, it drives the air spraying pipe 18 to move, so that the air spraying pipe 18 sprays air onto the surface of the special-shaped part to help remove the excess penetrant.
