[0002] Stainless steel pipes have been widely used in daily life, industrial production, architectural decoration and other fields due to their unique corrosion resistance, high strength and good processing performance. Before use, stainless steel pipes need to be polished to remove the surface oxide layer, rust and other impurities and reduce surface microscopic defects, which not only improves the corrosion resistance of stainless steel pipes, but also extends their service life.

[0003] The existing polishing device usually polishes straight stainless steel pipes. When polishing straight stainless steel pipes, the stainless steel pipes can be directly attached to the high-speed rotating polishing parts and pushed to achieve rapid polishing. However, when polishing curved stainless steel pipes, it is necessary to rotate or adjust the position of the stainless steel pipes for multiple times so that each surface of the stainless steel pipes contacts the polishing parts. This not only increases the complexity of the operation, but also prolongs the polishing time. Moreover, when changing polishing parts of different mesh sizes for multiple polishing, it is difficult to ensure that the polishing effects of various parts of the pipe circumference are consistent, which affects the overall aesthetics and quality consistency of the stainless steel pipes.

[0039] refer to Figures 9 to 11 As shown, a surface polishing device for stainless steel products is shown, the upper surface of the right side of the mounting member 14 is slidably connected with a sliding frame 52, and the left side of the middle of the sliding frame 52 is fixedly connected with a limiting tube 5, the sliding frame 52 is used to drive the limiting tube 5 to slide up and down, the top of the limiting tube 5 is squeezed and matched with the bottom of the limiting block 31, and when the limiting tube 5 moves upward, it is used to drive the limiting block 31 to move simultaneously, the interior of the limiting tube 5 is sleeved on the outer surface of one end of the pull rope 3, the outer surface of the front end of the winding member 35 is fixedly connected with the extrusion block 51, the winding member 35 is used to drive the extrusion block 51 to rotate simultaneously, and the outer surface of the extrusion block 51 is squeezed and matched with the inner side of the bottom of the sliding frame 52 The outer surface of the top of the sliding frame 52 is fixedly sleeved with a third spring 53, and the bottom end of the third spring 53 is fixedly connected to the upper surface of the right end of the mounting member 14.

[0040] The complete working principle and steps of the above embodiment are as follows:

[0041] refer to Figures 1 to 5As shown, when the polishing device is in the promoting state, the side of the extrusion members 13 that are close to each other is in a tightened state, the first motor 2 and the second motor 21 are in a closed state, and the first spring 251 is in a naturally relaxed state;

[0042] When using the device, first place the inner sides of the two ends of the U-shaped tube 11 on the upper surfaces of the two ends of the mounting member 14, and then rotate the bidirectional screw rods 12 on both sides to cause the extrusion member 13 to slide on the upper surface of the mounting member 14 to the side away from each other, causing the outer surface of the extrusion member 13 on the side away from each other to be fixed to the inner walls of the two ends of the U-shaped tube 11, and when the U-shaped tube 11 is placed on the upper surface of the mounting member 14, the outer surface of the U-shaped tube 11 will squeeze the outer surface of the polishing member 24, so that the polishing member 24 drives the sliding member 25 to move to the left, and when the sliding member 25 moves to the left, it will cause the first spring 251 to move to a stretched state, and the first spring 251 in a stretched state will drive the polishing member 24 to move to the left through the sliding member 25, so that the outer surface of the polishing member 24 can fit the outer surface of the U-shaped tube 11, and by starting the first motor 2 and the second motor 21, the output shaft of the first motor 2 can drive the rotation The rotating gear 22 rotates at the same time, and the outer surface of the rotating gear 22 drives the toothed disc 23 to rotate at the same time. When the toothed disc 23 rotates on the upper surface of the left side of the rotating member 26, it drives the sliding member 25 to rotate in a circle. When the sliding member 25 rotates in a circle, it drives the polishing member 24 to rotate at the same time. At this time, the polishing member 24 can perform circular rotation and polishing around the outer surface of the U-shaped tube 11, and the output shaft of the second motor 21 rotates, which drives the rotating member 26 to swing clockwise. When the rotating member 26 swings clockwise, it drives the toothed disc 23 and the sliding member 25 to swing at the same time. When the sliding member 25 swings, it drives the polishing member 24 to swing at the same time, prompting the polishing member 24 to swing clockwise when performing circular polishing on the outer surface of the U-shaped tube 11, so that the polishing member 24 can cover the entire outer surface of the U-shaped tube 11 more evenly, thereby avoiding the problem of insufficient or excessive polishing in some parts, and making the surface of the U-shaped tube 11 smoother and brighter.

[0043] refer to Figure 6 As shown, when the polishing device is in the urged state, the second spring 34 is in a naturally relaxed state, and the locking member 33 has not yet been inserted into the inner side of the limiting block 31;

[0044] Before polishing the outer surface of the U-shaped tube 11, the staff can pass the drawstring 3 on the outer surface of the winding member 35 through the inner side of the U-shaped tube 11, and when the drawstring 3 passes through the inside of the U-shaped tube 11, it will drive the limiting block 31 to pass through at the same time. At this time, the staff can pull the locking member 33 to the right, and when the locking member 33 slides to the right at the bottom of the right side of the mounting member 14, it will drive the second spring 34 to move to a stretched state, so that the outer surface of the locking member 33 can be aligned with the circular hole through which the limiting block 31 is opened. When the staff lets go, the second spring 34 in the stretched state will drive the locking member 33 to move to the left through the circular hole through which the outer surface of the limiting block 31 is opened, so that the limiting block 31 can be closed. When the limiting block 31 is fixed and the locking piece 33 moves to the left and passes through the circular hole of the limiting block 31, the left end of the locking piece 33 will be squeezed to the right side of the switch button 32, so that the switch button 32 can drive the output shaft of the third motor 36 to rotate. When the output shaft of the third motor 36 rotates, the winding piece 35 will be driven to rotate at the same time. When the winding piece 35 rotates, the pull rope 3 can be stretched, so that the outer surface of the pull rope 3 can fit the inner wall of the U-shaped tube 11, thereby providing additional fixation for the U-shaped tube 11, so that the U-shaped tube 11 will not be polished or displaced during the polishing process, thereby improving the stability of the polishing and helping to ensure the stability and consistency of the polishing quality.

[0045] After the polishing of the U-shaped tube 11 is completed, the staff can pull the locking piece 33 to the right, and the left end of the locking piece 33 will be disengaged from the right side of the switch button 32, and the outer surface of the locking piece 33 will be disengaged from the inner side of the limiting block 31. At this time, the third motor 36 can be started to make the output end of the third motor 36 drive the winding piece 35 to rotate in the opposite direction. When the winding piece 35 rotates in the opposite direction, it will drive the limiting block 31 to move to the left through the pull rope 3, so that the pull rope 3 and the limiting block 31 can be disengaged from the inner side of the U-shaped tube 11, making it convenient to remove the U-shaped tube 11.

[0046] refer to Figure 7 and Figure 8As shown, as the sliding member 25 swings clockwise, the wedge block 43 is driven to swing simultaneously. When the wedge block 43 swings clockwise by 180 degrees, the inclination of the upper surface of the wedge block 43 will fit the upper surface of the right extrusion rod 42 and cause the wedge block 43 to move to the right. When the wedge block 43 moves to the right, the first spring 251 is caused to move to a stretched state, and the outer surface of the top one-way gear 44 will mesh with the rear side of the right rack 41. As the sliding member 25 drives the one-way gear 44 to move to the right through the polishing member 24, the outer surface of the top one-way gear 44 will mesh with the rear side of the right end rack 41, causing the top one-way gear 44 to rotate sixty degrees clockwise. When the one-way gear 44 rotates clockwise, The polishing member 24 will be driven to rotate sixty degrees at the same time, thereby changing the polishing mesh number of the polishing member 24. As the sliding member 25 drives the wedge block 43 to flip counterclockwise, the inclined surface of the upper surface of the wedge block 43 will be out of contact with the top of the right extrusion rod 42, and the first spring 251 in the stretched state will drive the polishing member 24 and the one-way gear 44 to move leftward. When the top one-way gear 44 moves leftward, it will mesh with the rear side of the right end rack 41, causing the top one-way gear 44 to rotate clockwise. Since the one-way gear 44 can only rotate counterclockwise, the one-way gear 44 will not drive the polishing member 24 to rotate at the same time when it rotates clockwise. As the wedge block 43 flips counterclockwise by 180 degrees, the wedge The inclined surface at the bottom of the block 43 will fit the upper surface of the left extrusion rod 42, causing the wedge block 43 to move to the left. When the one-way gear 44 turns counterclockwise by 180 degrees, the outer surface of the bottom one-way gear 44 will mesh with the rear side of the rack 41 at the left end. When the wedge block 43 moves to the left, it will drive the first spring 251 to move to a stretched state. When the wedge block 43 drives the sliding member 25 to move to the right, the polishing member 24 and the one-way gear 44 will also move at the same time. When the bottom one-way gear 44 moves to the left, it will mesh with the rear side of the rack 41 at the left end, causing the bottom one-way gear 44 to rotate counterclockwise. Since the one-way gear 44 can only rotate counterclockwise, the bottom one-way gear 44 does not rotate when it rotates. The polishing member 24 will be driven to rotate at the same time. As the wedge block 43 rotates clockwise, the inclined surface at the bottom of the wedge block 43 will be out of contact with the top of the left extrusion rod 42, and the first spring 251 in a stretched state will drive the sliding member 25 and the one-way gear 44 to move right. When the rear side of the left end rack 41 moves right, the one-way gear 44 will be prompted to rotate clockwise. When the one-way gear 44 at the bottom rotates clockwise, the polishing member 24 will be driven to rotate sixty degrees again to change the polishing degree, so that the extrusion rod 42 can continuously polish the outer surface of the U-shaped tube 11 from coarse to fine, so that the outer surface of the U-shaped tube 11 can obtain a more delicate and uniform polishing effect.

[0047] refer to Figures 9 to 11As shown, when the polishing device is in the urged state, the top of the limiting tube 5 is in contact with the lower surface of the limiting block 31, the outer surface of the squeezing block 51 is in contact with the inner side of the bottom of the sliding frame 52, and the third spring 53 is in a compressed state;

[0048] When the U-shaped tube 11 is installed on the upper surface of the mounting member 14, the bidirectional screw rods 12 on both sides can be rotated to move the extrusion members 13 on both sides to the side away from each other to fix the inner wall of the U-shaped tube 11, and the latch 111 is pulled forward to pull the rear end of the latch 111 out of the circular hole at the bottom of the limiting plate 112, and the staff can turn the mounting member 14 counterclockwise by 90 degrees. When the mounting member 14 rotates counterclockwise, the U-shaped tube 11 will be driven to rotate at the same time, causing the U-shaped tube 11 to be turned to a vertical state. At this time, the staff can push the latch 111 backward to insert the rear end of the latch 111 into the circular hole at the top of the limiting plate 112, and start the third motor 36 to make the output end of the third motor 36 drive the winding member 35 to rotate counterclockwise, and the winding member 35 When it rotates counterclockwise, the extrusion block 51 will be driven to rotate at the same time. When the extrusion block 51 rotates counterclockwise, it will be out of contact with the inner side of the bottom of the sliding frame 52. At this time, the third spring 53 in a compressed state will drive the sliding frame 52 to move upward, and when the sliding frame 52 moves upward, it will drive the limiting tube 5 to move at the same time. When the limiting tube 5 moves upward, it will push the bottom of the limiting block 31, so that the limiting block 31 can drive the pull rope 3 to push toward the inside of the U-shaped tube 11. Since the U-shaped tube 11 is in a vertical state, the limiting block 31 will slide downward inside the U-shaped tube 11 due to gravity when it is inside the U-shaped tube 11, so that the limiting block 31 can drive the pull rope 3 to slide smoothly from the inside of the U-shaped tube 11, thereby reducing the difficulty of installing the pull rope 3 and making the installation process faster and more convenient.

[0049] When the pull rope 3 is installed, the staff can pull the pin 111 forward again to disengage the rear end of the pin 111 from the circular hole on the top of the limiting plate 112. At this time, the staff can flip the mounting piece 14 clockwise by ninety degrees so that the mounting piece 14 drives the U-shaped tube 11 back to a horizontal state, and can also push the pin 111 backward so that the rear end of the pin 111 is engaged in the circular hole on the right side of the limiting plate 112, thereby fixing the mounting piece 14 to prevent shaking during polishing.

[0050] When the polishing of the U-shaped tube 11 is finished, the staff can start the third motor 36, so that the output end of the third motor 36 drives the winding member 35 to rotate clockwise. When the winding member 35 rotates clockwise, it drives the pull rope 3 and the extrusion block 51 to rotate simultaneously. At this time, since there is a gap between the inner side of the bottom of the sliding frame 52 and the bottom of the extrusion block 51, the extrusion block 51 will not fit with the inner side of the bottom of the sliding frame 52 during rotation. As the pull rope 3 is wound clockwise, it drives the limiting block 31 to move simultaneously, so that the pull rope 3 and the limiting block 31 can When the limiting block 31 is driven by the pull rope 3 to move downward, the bottom of the limiting block 31 can fit against the top of the limiting tube 5 and drive the limiting tube 5 to slide downward. When the limiting tube 5 slides downward, it will drive the sliding frame 52 to slide at the same time. When the sliding frame 52 slides downward inside the mounting member 14, the third spring 53 can be moved back to the compressed state. When the sliding frame 52 moves downward, the inner side of the bottom of the sliding frame 52 can fit against the bottom of the extrusion block 51 again, so as to facilitate the next use.
