[0018] 1. The device for grinding the weld seam inside a high-clean stainless steel pipe comprises a placing ring, a stainless steel pipe body, a fastening ring, a sliding groove, a sliding block, a motor body, a rotating shaft, a rotating ring, a connecting cylinder, a grinding arc block, a first limiting roller, a belt body, a second limiting roller, a fixed shaft, a mounting shaft, a driving gear, a first driven gear and a second driven gear. When in use, the stainless steel pipe body is first mounted on the surface of the placing ring, and the position of the stainless steel pipe body is limited by the fastening ring. The fastening ring is elastic and can stably mount the stainless steel pipe body on the surface of the placing ring. Then, the rotating ring and the grinding arc block are mounted inside the stainless steel pipe body. At this time, the two groups of grinding arc blocks can contact the inner weld seam inside the stainless steel pipe body. Then, the motor body is started and the rotating shaft is driven to rotate by the motor body. Then, the rotating ring and the grinding arc block are driven to rotate by the rotating shaft. The welding seam inside the stainless steel pipe body can be grinded by the grinding arc block, and the overall grinding effect is good. At the same time, when the rotating shaft rotates, the rotating shaft will also drive the first limiting roller to rotate, and then the first limiting roller will drive the belt body and the second limiting roller to rotate. At this time, the second limiting roller will drive the installation shaft to rotate, and at the same time the installation shaft will drive the driving gear to rotate, and then the driving gear and the first driven gear and the second driven gear are meshed with each other, and the rotation directions are consistent, so that the first fan blade and the second fan blade can be driven to rotate. When the first fan blade and the second fan blade rotate, air can be blown to the left, and the blowing place is the grinding place. The rotation of the first fan blade and the second fan blade can blow away the debris generated at the grinding place to avoid the accumulation of debris on the inner bottom wall of the stainless steel pipe body, which affects the grinding of the arc block and the inner weld of the stainless steel pipe body. Therefore, the design has a better effect on the processing of debris. At the same time, the fixed shaft, the first connecting rod and the second connecting rod are limited by the mounting column and the limiting frame respectively, and the overall limiting effect is good. Therefore, the design can blow away the debris while grinding, which reflects the functionality of the design.

[0019] 2. The device for grinding the weld seam inside a high-clean stainless steel pipe is provided with a first connecting rod, a first fan blade, a second fan blade, a pushing ring, a mounting column, a limiting frame, a limiting block, a rack plate body, a gear column, a rotating cylinder, an arc groove, a convex column, a lifting rod and a top column. When the grinding is completed, the electric push rod body is started, and the electric push rod body can drive the side block and the sliding block to move. At this time, the sliding block will slide to the left inside the sliding groove, and the overall sliding is relatively stable. Then the sliding block will drive the motor body and the rotating ring to move, so that the rotating shaft and the rotating ring will slide inside the stainless steel pipe body. When the sliding block is sliding, since the pushing ring is installed on the lower surface of the first connecting rod and the second connecting rod, the debris on the bottom wall of the stainless steel pipe body can be scraped off by the pushing ring. The debris can be scraped off more comprehensively by the pushing ring, and the overall scraping effect is good. At the same time, when the sliding block moves, the limiting block will drive the rack plate body to move to the left. At this time, the rack plate body will drive the gear column to rotate, and then the gear column will drive the rotating cylinder to rotate. The lifting rod is lifted up, and the top column and the movable frame are lifted up, so that the movable frame can lift the stainless steel pipe body. At this time, the left side of the stainless steel pipe body is slightly lower than the right side, so that the debris can be automatically moved to the left side through the inclined design of the push ring and the stainless steel pipe body, so that the overall impurity removal effect is better, and the mounting sleeve is elastic at this time. If the bonding plate is subjected to pressure, the spring design of the mounting sleeve can automatically fit the left side surface of the stainless steel pipe body, so that the position of the stainless steel pipe body can be limited. At the same time, when the rotating shaft moves to the left as a whole, the connecting cylinder can drive the grinding arc block to approach the rotating ring, so that the grinding arc block will not limit the angle adjustment of the stainless steel pipe body when moving. This design can continue to push and clean the debris that falls on the bottom wall of the stainless steel pipe body after grinding, and can also fine-tune the angle of the stainless steel pipe body, so that the debris flows out from the left side of the stainless steel pipe body under gravity, which reflects the ingenuity of the design.

Then the driving gear 18 is meshed with the first driven gear 19 and the second driven gear 20, and the rotation directions are consistent, so that the first blade 22 and the second blade 23 can be driven to rotate. When the first blade 22 and the second blade 23 rotate, air can be blown to the left, and the blowing place is the grinding place. The rotation of the first blade 22 and the second blade 23 can blow the debris generated at the grinding place to avoid the accumulation of debris on the inner bottom wall of the stainless steel pipe body 4 to affect the grinding of the inner weld of the grinding arc block 12 and the stainless steel pipe body 4. Therefore, the present design has a better effect on the processing of debris. At the same time, the fixed shaft 16, the first connecting rod 21 and the second connecting rod are limited by the mounting column 25 and the limiting frame 26 respectively.

[0034] When the grinding is finished, the electric push rod body 41 is started, and the electric push rod body 41 can drive the side block 40 and the sliding block 7 to move.
