[0029] Refer to Figures 2-5As shown, one end of bolt 10 passes through the fixed frame 4 and extends outward from the fixed frame 4. Bolt 10 is threadedly connected to the fixed frame 4. A rotating shaft 11 is fixedly installed at the output end of motor 3. A first pulley 12 is fixedly installed on one side of the rotating shaft 11. A support frame 13 is fixedly installed on one side of support plate 2. A second pulley 14 is rotatably installed on one side of support frame 13. A support arm 15 is fixedly installed on one side of support frame 13. A roller 16 is rotatably installed on one side of support arm 15. After motor 3 starts, the rotating shaft 11 at its output end drives the first pulley 12 to rotate. Since the first pulley 12 and roller 16 are... The second pulley 14, multiple third pulleys 17, and adjusting pulley 8 are connected by a belt 18. Under the transmission action of the belt 18, they rotate synchronously, thereby driving the sanding belt 19 fixed on one side of the belt 18 to perform cyclical motion. The support frame 13 supports the support arm 15. The roller 16 rotatably set on one side of the support arm 15 assists the transmission of the belt 18, so that the belt maintains a suitable path and tension distribution during operation. On the other hand, it also provides a certain support and guidance for the movement of the sanding belt 19, ensuring that the sanding belt 19 can run smoothly and maintain a good contact state with the blade when polishing the blade.

[0030] Reference Figures 6-7 As shown, multiple third pulleys 17 are rotatably mounted on one side of the support plate 2.

After the blade is fixed by an external clamping device, an external robotic arm drives the blade close to the sanding belt 19 for polishing. The angle of the blade is adjusted by the rotation axis of the external robotic arm to make its contact with the sanding belt 19 more precise, achieving accurate polishing.

[0031] Working principle of this utility model:

[0032] This utility model is a blade polishing mechanism. When the device is in use, after the motor 3 is started, the rotating shaft 11 at its output end drives the first pulley 12 to rotate. Since the first pulley 12, the roller 16, the second pulley 14, multiple third pulleys 17 and the adjusting pulley 8 are connected by the belt 18, they rotate synchronously under the transmission action of the belt 18, thereby driving the sanding belt 19 fixed on one side of the belt 18 to perform cyclical motion.

[0033] The rolling bearing 20 is installed outside the rotating shaft 11 and connected with the support plate 2, which enables the rotating shaft 11 to rotate flexibly and stably, reduces friction resistance, ensures that the power of the motor 3 can be efficiently transmitted to the abrasive belt 19, and makes the abrasive belt 19 run at a stable linear speed, ensuring the uniformity and stability of polishing. After the blade is fixed by the external clamping device, the blade is driven by the external robot arm to approach the abrasive belt 19 for polishing operation. The angle of the blade is adjusted by the rotating shaft of the external robot arm, so that the contact between the blade and the abrasive belt 19 is more fitted, and precise polishing is realized.

[0034] The locking abrasive belt mechanism is used to adjust the tension of the abrasive belt 19. The moving rod 5 slides in the moving groove of the fixed frame 4, and the movable block 6 at one end slides in the through groove 7. The adjusting pulley 8 on the movable block 6 changes position with the movement of the movable block 6. When it is necessary to adjust the tension of the abrasive belt, the bolt 10 is loosened, the movable block 6 is pushed to move along the guide bar 9, the tension of the adjusting pulley 8 on the belt 18 is changed, and after the appropriate position is adjusted, the bolt 10 is tightened to fix the movable block 6, so as to realize the precise adjustment of the tension of the abrasive belt 19. In this way, the problems of slipping of the abrasive belt 19 due to too loose tension, affecting the polishing efficiency and quality, or breaking of the abrasive belt 19 and excessive load of the motor 3 due to too tight tension can be avoided.

[0035] The support frame 13 supports the support arm 15, and the roller 16 rotatably arranged on one side of the support arm 15 assists the transmission of the belt 18, so that the belt maintains appropriate path and tension distribution during operation, and also supports and guides the movement of the abrasive belt 19 to a certain extent, ensuring that the abrasive belt 19 can run stably when polishing the blade and maintain good contact with the blade.

[0036] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
