Detailed Embodiment

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1: A surface polishing machine for stainless steel pipes. Please refer to Figures 1-7 , which includes a chassis 1, a protective shell 2, a support shell 3, a drive motor 4, a polishing roller 5, a limiting cylinder 6, a placement plate 16 and a placement frame 17. A protective shell 2 is fixedly connected to the front side of the chassis 1. Two support shells 3 are slidably arranged in the protective shell 2. A drive motor 4 is arranged in the support shell 3 by welding. A polishing roller 5 is connected to the output shaft of the drive motor 4. A limiting cylinder 6 is fixedly connected to the chassis 1. A placement plate 16 is fixedly connected to the rear side of the limiting cylinder 6. A placement frame 17 is fixedly connected to the rear side of the chassis 1. Four clamping blocks 7 are slidably arranged on both the front and rear sides of the limiting cylinder 6. Two vertically aligned clamping blocks 7 are jointly arranged by welding with a connecting rod 8. A push plate 9 is rotatably arranged in the middle of the limiting cylinder 6. The connecting rod 8 slides in the push plate 9. A connecting seat 10 is fixedly connected to the push plate 9. A support frame 11 is fixedly connected to the placement frame 17. An electric slide rail 12 is arranged on the support frame 11. An electric slider 13 is slidably arranged on the electric slide rail 12. A push frame 14 is fixedly connected to the bottom of the electric slider 13. The push frame 14 is slidably connected to the connecting seat 10. A connecting plate 15 is fixedly connected to the rear side of the support shell 3. One end of the connecting plate 15 is connected to the clamping block 7 at the corresponding position. A protective pad 30 is embedded on the inner wall of the clamping block 7. The protective pad 30 reduces the pressure between the clamping block 7 and the stainless steel pipe, avoiding deformation of the stainless steel pipe caused by the pressure.

[0026] When it is necessary to polish the stainless steel pipe, the stainless steel pipe is first passed through the limiting cylinder 6 and fixed by the clamping block 7 to prevent one end of the stainless steel pipe from tilting during the polishing process and affecting the polishing effect. Then, the stainless steel pipe is pushed forward to make it contact with the polishing roller 5. At this time, the drive motor 4 is started, the output shaft of the drive motor 4 rotates and drives the polishing roller 5 to rotate, thereby polishing and grinding the surface of the stainless steel pipe. If it is necessary to polish stainless steel pipes of different diameters, after the stainless steel pipe is passed through the limiting cylinder 6, the electric slide rail 12 is started, so that the electric slider 13 drives the pushing frame 14 to move, and the pushing frame 14 drives the connecting seat 10 to move, thereby prompting the pushing disk 9 to rotate, driving the connecting rod 8 to move inward or outward, so that the clamping block 7 clamps the stainless steel pipe more accurately. At the same time, it will also drive the connecting plate 15 to move inward or outward, so that the support shell 3 also adjusts its position accordingly, thereby changing the distance between the two polishing rollers 5, thereby ensuring that the polishing machine can adapt to stainless steel pipes of different sizes and improving the applicability and work efficiency of the equipment.

[0027] Example 2: Based on Example 1, please refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 A sliding plate 18 is slidingly provided on the outside of the placement plate 16, and a connecting ring 19 is fixedly connected to the rear side of the sliding plate 18. A limiting block 20 is fixedly connected to the placement plate 16, and the limiting block 20 limits the sliding plate 18 to prevent the sliding plate 18 from falling off. A sliding shell I 21 is fixedly connected to the rear side of the support frame 11, and a sliding shell II 22 is provided on the connecting ring 19 by welding. The sliding shell I 21 and the sliding shell II 22 are slidingly provided with a sliding frame 23. The sliding shell I 21 and the sliding shell II 22 are fixedly connected to guide blocks 24 on the left and right sides. A pull handle 28 is fixedly connected to the connecting ring 19. The pull handle 28 increases the fulcrum between the hand and the connecting ring 19, thereby facilitating pulling the connecting ring 19. A sliding frame 29 is fixedly connected to the bottom of the connecting ring 19. When the connecting ring 19 is pulled, the moving wheel on the sliding frame 29 rotates accordingly, assisting the connecting ring 19 to move.

[0028] When it is necessary to polish stainless steel tubes of different lengths, the connecting ring 19 is pulled backward to drive the sliding plate 18 to move backward to expand it, thereby extending the length of the placement plate 16. At the same time, the sliding shell II 22 also moves backward to expand the space of the sliding frame 23, so that the polishing machine can place stainless steel tubes of different lengths. Then, the stainless steel tube is placed in the sliding frame 23 and then dropped onto the placement plate 16 through the discharge port at the bottom of the sliding frame 23.

[0029] See also Figure 7 and Figure 8, mounting brackets 27 are provided on both the left and right sides of the connecting ring 19 by welding, and an electric push rod 25 is provided by welding the two mounting brackets 27 together. A push plate 26 is connected to the telescopic rod of the electric push rod 25.

[0030] After the stainless steel pipe falls on the placement plate 16, the electric push rod 25 is turned on, and the telescopic rod of the electric push rod 25 is controlled to extend, so that the push plate 26 pushes the stainless steel pipe forward until the stainless steel pipe enters the inside of the limiting cylinder 6, thereby achieving the purpose of automatic feeding and improving the polishing efficiency.
