[0028] Further, the rotating sleeve 23 is arranged between the two clamping plates 21, the key shafts 22 are matched with the key grooves 24, the rotating sleeve 23 can be axially clamped and fixed by the two clamping plates 21, and the key shafts 22 can be inserted into the key grooves 24 to prevent the rotating sleeve 23 from driving the impeller blades 25 to rotate.

[0029] Further, the left polishing strip 17 and the right polishing strip 20 are arranged alternately, and the left polishing strip 17 and the right polishing strip 20 will not interfere with each other when they approach each other.

[0030] Further, the left polishing strip 17 and the right polishing strip 20 are located between adjacent two impeller blades 25, the left polishing strip 17 and the right polishing strip 20 will not contact when they approach each other, when the left polishing strip 17 moves from left to right, the left side surface of the impeller blade 25 can be polished first, and then the right side surface of the impeller blade 25 can be polished, when the right polishing strip 20 moves from right to left, the right side surface of the impeller blade 25 can be polished first, and then the left side surface of the impeller blade 25 can be polished, so that the impeller blade 25 can be polished more thoroughly and efficiently.

[0031] Further, the diameters of the left rotating disc 16 and the right rotating disc 19 are smaller than the gap size between adjacent two impeller blades 25, so that the left rotating disc 16 and the right rotating disc 19 can pass through the gap between adjacent two impeller blades 25, avoiding damaging the impeller blades 25.

The abrasive is attached to a flexible base material, and the base material generally has a certain flexibility, such as paper, cloth, or fiber material. Such a flexible base material allows the polishing strip to better fit the surface of a workpiece of various shapes, including curved surfaces and concave-convex surfaces, and to achieve more comprehensive polishing.

[0034] Further, the left cylinder 3 and the left pneumatic rod 4 are symmetrically arranged with the right cylinder 5 and the right pneumatic rod 6, which facilitates the left pneumatic rod 4 and the right pneumatic rod 6 to simultaneously drive the clamping plates 21 and the key shafts 22 on their respective sides to move closer to each other, so as to clamp and fix the impeller blades 25.

[0035] In use, the impeller blades 25 are placed between the two key shafts 22, and then the left cylinder 3 and the right cylinder 5 are simultaneously started, so that the left pneumatic rod 4 and the right pneumatic rod 6 can respectively drive the clamping plates 21 and the key shafts 22 on their respective sides to move closer to each other. When the key shafts 22 on both sides are simultaneously inserted into the key grooves 24, the clamping plates 21 on both sides also come into contact with the rotating sleeve 23. Therefore, the rotating sleeve 23 can be clamped and fixed by the clamping plates 21 on both sides, and thus the impeller blades 25 can also be clamped and fixed. The key shafts 22 can prevent the rotating sleeve 23 from rotating with the impeller blades 25, so that the impeller blades 25 can be stably clamped and fixed for polishing and cleaning the surface of the impeller blades 25. When the impeller blades 25 are fixed, the left rotating disc 16 and the right rotating disc 19 are located between adjacent impeller blades 25.

The right adjusting cylinder 12 is started to drive the right adjusting pneumatic rod 13 to move the right motor 18, the right rotating disc 19, and the right polishing strip 20 to the left through the mounting plate 14. The left motor 15 drives the left polishing strip 17 to rotate through the left rotating disc 16, and the right motor 18 drives the right polishing strip 20 to rotate through the right rotating disc 19. Because the left polishing strips 17 and the right polishing strips 20 are staggered and arranged, they do not interfere with each other when they move closer to each other. Therefore, the left polishing strips 17 can polish and clean the surface of the impeller blades 25 from left to right, and the right polishing strips 20 can polish and clean the surface of the impeller blades 25 from right to left, so that the impeller blades 25 can be polished more efficiently and thoroughly, thereby improving the efficiency of polishing and cleaning the impeller blades 25.
