The second driving device 13 is connected to the mounting seat 12; the second driving device 13 is selected but not limited to a motor; the output end of the second driving device 13 is connected to one end of the output shaft 14. The grinding wheel 15 and the other end of the output shaft 14 are detachably connected by bolts. The protection assembly is connected to the linear motor 11; in the use state of the protection assembly, the protection assembly gradually fits with the outer wall of the stainless steel pipe, thereby forming a cylindrical closed space to reduce the pollution of the surrounding environment by dust.

[0030] The protection assembly includes a mounting plate 16, a protective cover 17 and a closing assembly. The mounting plate 16 is connected to the second driving device 13. The mounting plate 16 is arranged parallel to the grinding wheel 15. The protective cover 17 is connected to the side of the fixed plate 9 close to the grinding wheel 15 through a flange; the closing assembly is connected to the protective cover 17; in the use state of the closing assembly, the closing assembly moves synchronously towards the center of the protective cover 17 to contact the steel pipe. The closing assembly cooperates with the mounting plate 16 and the protective cover 17 to form a cylindrical cavity to collect the metal chips and dust generated by grinding, reducing the pollution and danger brought by grinding to the surrounding environment.

[0031] The closed component includes a fixed ring 18, a sliding block 19, a moving rod 20, a limiting block 21 and an elastic member 22. The fixed ring 18 is connected to the protective cover 17, and the fixed ring 18 is arranged parallel to the mounting plate 16. There are multiple sliding blocks 19 distributed circumferentially around the central axis of the fixed ring 18.

[0033] In summary, when the utility model is in use, the staff controls the telescopic end of the telescopic device 7 to extend, and the moving seat 8 moves away from the fixed seat 6 along with the telescopic end of the telescopic device 7. The fixed plate 9 and the moving plate 10 move away from each other to form a cavity for facilitating the insertion of the stainless steel pipe. After the steel pipe is inserted, the telescopic device 7 is started again. The telescopic end of the telescopic device 7 drives the moving seat 8 and the moving plate 10 to move towards the fixed seat 6. The moving plate 10 is inserted into the gap between the two fixed plates 9. The V-shaped grooves formed on the fixed plate 9 and the moving plate 10 limit the stainless steel pipe. The rubber layers connected to the fixed plate 9 and the moving plate 10 can further increase the friction force with the stainless steel pipe, prevent the stainless steel pipe from loosening and scratching the surface of the stainless steel pipe, accelerating corrosion and oxidation. When performing the grinding operation, the staff starts the linear motor 11 to move the mounting seat 12 and the second driving device 13 to one end of the stainless steel pipe. After the second driving device 13 is started, it will drive the output shaft 14 and the grinding wheel 15 to rotate, and the grinding wheel 15 grinds the stainless steel pipe. At the same time, when the grinding wheel 15 approaches the stainless steel pipe, the protective cover 17 will be sleeved on its outer side. The sliding block 19 contacts one end of the stainless steel pipe. Through the conveyance of the linear motor 11, the stainless steel pipe contacts the inclined surface of the sliding block 19. The two move towards each other and push the sliding block 19 to move towards the limiting block 21 and compress the length of the elastic member 22. After the stainless steel pipe enters the protective cover 17, its contact and restriction with the sliding block 19 are achieved. The length of the elastic member 22 is restored to push the sliding block 19 to closely adhere to the stainless steel pipe. The rubber layer connected to the arc-shaped block is used to adhere to the stainless steel pipe and prevent excessive metal dust and sparks from flying and polluting the surrounding air. The collected debris is guided into the collection box 23 through the annular protective cover 17. After the collection is completed, it can be disassembled by bolts.
