Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 and Figure 2 The utility model provides an embodiment: an automatic grinding device for the inner wall of a stainless steel pipe, including a stabilizing seat 1 for providing stability and installation of other components, a protective block 2 is slidably connected to the top of the stabilizing seat 1 for providing protection, a driving assembly for transmission is installed inside the protective block 2, and the driving assembly includes a double-headed motor 3, a motor with two rotating shafts that can realize bidirectional rotation and provide power, the outside of the double-headed motor 3 is fixedly connected to the inside of the protective block 2, the rear driving end of the double-headed motor 3 is fixedly connected to a rotating rod 4, and a grinding cylinder 5 is fixedly connected to the rear side of the driving assembly, the rotating rod 4 is used to connect the grinding cylinder 5, and the grinding cylinder 5 can be polished by starting the double-headed motor 3, and a stainless steel pipe body 6 is provided on the top of the stabilizing seat 1, which is the raw material of the stainless steel pipe.

[0033] Reference Figure 1 、 Figure 3 and Figure 4 , the interior of the stable seat 1 is fixedly connected with a cylinder 7 for providing driving power, the driving end of the cylinder 7 is fixedly connected with a push block 8, the front side of the push block 8 is fixedly connected with a limiting block 9, the cylinder 7 pushes the push block 8 to rise and fall, and with the cooperation of the limiting block 9, the push block 8 can be made to rise and fall more smoothly, the rear side of the push block 8 is rotatably connected to two rotating blocks 10, the front side of the rotating block 10 is rotatably connected to a connecting block 11, the outside of the connecting block 11 is fixedly connected with a connecting block 12, and the left and right sides of the stable seat 1 are fixedly connected with differential blocks 13;

[0034] The descent of the pushing block 8 will cause the two rotating blocks 10 to rotate to the left and right sides respectively. The outside of the limiting block 9 is slidably connected to the inside of the stabilizing seat 1, and the outside of the connecting block 12 is rotatably connected to the outside of the differential block 13. The connecting block 11 enables the connecting block 12 to rotate under the rotation connection of the differential block 13. The rear side of the connecting block 12 is rotatably connected to the pushing block 14. The adjacent sides of the two pushing blocks 14 are rotatably connected to the clamping blocks 15. The adjacent sides of the two clamping blocks 15 are fixedly connected with the anti-slip pads 16. The outside of the clamping blocks 15 is slidably connected to the inside of the stabilizing seat 1, and the outside of the anti-slip pads 16 is in contact with the outside of the stainless steel pipe body 6. The rotation of the two connecting blocks 12 will push the two pushing blocks 14 to move toward the middle, so that the clamping blocks 15 can clamp the stainless steel pipe body 6 through the anti-slip pads 16, thereby preventing the stainless steel pipe body 6 from rotating during the grinding process.

[0035] Reference Figure 1 、 Figure 4 and Figure 5 , a circular scraper 17 is fixedly connected to the rear side of the grinding cylinder 5, which is used to scrape out the debris generated when the stainless steel pipe body 6 is ground. The outer side of the circular scraper 17 contacts the inner wall of the stainless steel pipe body 6. The internal rotation of the protective block 2 is connected to the connecting rod 18. Two cone wheels 19 are provided inside the protective block 2. The front driving end of the double-headed motor 3 can drive the cone wheels 19 to rotate. The interior of one of the cone wheels 19 is fixedly connected to the exterior of the connecting rod 18. The two cone wheels 19 are meshed. Under the meshing connection of the two cone wheels 19, the connecting rod 18 can rotate accordingly;

[0036] The left and right sides of the protective block 2 are fixedly connected with sliders 20 for limiting the movement of the protective block 2 to prevent deviation. The outer rotation of the connecting rod 18 is connected to the inner part of the slider 20. The left and right sides of the connecting rod 18 are fixedly connected to gears 21. The top of the stable seat 1 is fixedly connected with two slide boxes 22. The inner part of the slide box 22 is fixedly connected with a toothed plate 23. The outer part of the slider 20 is slidably connected to the outer part of the slide box 22. The outer part of the gear 21 is meshed with the outer part of the toothed plate 23. Under the rotation of the connecting rod 18, the gear 21 will be able to drive the protective block 2 forward and backward through the cooperation of the toothed plate 23. The inner wall of the stable seat 1 is slidably connected with a collection box 24. The right side of the collection box 24 is fixedly connected with a handle 25, so that the debris generated by the grinding inside the stainless steel pipe body 6 can enter the interior of the collection box 24 through the debris opening opened by the stable seat 1, so that the collection box 24 can be pulled out by the handle 25 to clean the internal debris.

[0037] Working principle: when it is needed, the stainless steel pipe body 6 is placed in the position set on the top of the stable seat 1, and then the cylinder 7 is started, so that the cylinder 7 pushes the pushing block 8. At the same time, under the protection and restriction of the limiting block 9, the pushing block 8 can be lifted and lowered more smoothly. While descending, it will drive the rotating block 10, so that the two rotating blocks 10 rotate to the left and right, thereby pushing the connecting block 11 to move, so that the connecting block 11 can drive the connecting block 12. Under the rotation restriction of the differential block 13, the connecting block 11 will drive the connecting block 12 to push the pushing block 14. Because it is a rotating connection, the pushing block 14 will push the clamping block 15, so that the two clamping blocks 15 slide to the near side inside the stable seat 1, so that the two anti-slip pads 16 can fit the outside of the stainless steel pipe body 6, and the stainless steel pipe body 6 is limited and fixed. At this time, the double-headed motor 3 inside the protective block 2 is started, so that the double-headed motor 3 drives the rotating rod 4 to rotate clockwise, so that the grinding cylinder 5 can grind the inner wall of the stainless steel pipe body 6;

[0038] While polishing the inner wall of the stainless steel pipe body 6, the rotation of the front driving end of the double-headed motor 3 will drive one of the cone wheels 19, cooperate with the other cone wheel 19, and then enable the connecting rod 18 to rotate accordingly. The rotation of the connecting rod 18 can also drive the two gears 21, and cooperate with the meshing connection with the tooth plate 23, so that the protective block 2 can be driven to slide backward on the top of the stable seat 1. At the same time, it is restricted by the two sliders 20, so that it can slide more smoothly, and then the polished debris is scraped out by the circular scraper 17, and then falls into the interior of the collection box 24 through the debris opening opened by the stable seat 1, and then the polished debris is collected. The collection box 24 can be taken out by pulling the handle 25 to the right.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
