Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel pipe processing, and particularly relates to a polishing device for stainless steel equipment production. Background Art

[0002] In the production of stainless steel equipment, the end polishing of stainless steel pipes is a key link to ensure the connection strength and appearance quality of pipe fittings. However, the traditional polishing mechanism has significant technical defects in end processing, resulting in severely limited processing efficiency and accuracy. Most traditional clamping mechanisms use single-end fixed chucks, and the covered area of the chuck occupies a length of 10 - 30 mm at the end of the steel pipe, resulting in this area not being directly contacted by the polishing wheel, forming a "clamping blind area". For example, in the polishing of stainless steel pipes for medical equipment, if there are unpolished blind areas on the end sealing surface, it may cause risks such as liquid leakage or bacterial growth.

[0003] Therefore, it is necessary to design a polishing device for stainless steel equipment production to facilitate the rapid polishing of both ends of stainless steel pipes. Summary of the Invention

[0029] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0030] As an embodiment of the present invention, as Figures 1 to 9 shown, a polishing device for stainless steel equipment production according to the present invention includes a support track 1, two sets of clamping mechanisms 2 slidably connected to the support track 1 for clamping the ends of a stainless steel pipe and driving the stainless steel pipe to rotate. The two sets of clamping mechanisms 2 are arranged symmetrically in a mirror image and move along the axial direction of the stainless steel pipe. A polishing mechanism 3 for polishing the outer side of the stainless steel pipe is arranged on one side of the support track 1. An auxiliary structure 4 for rolling and supporting the stainless steel pipe is arranged between the two sets of clamping mechanisms 2. A moving base slidably connected to the support track 1 is arranged between the two sets of clamping mechanisms 2. The two sets of clamping mechanisms 2 are respectively connected to the ends of the support track 1 through elastic supports 5.

[0031] During use, the stainless steel pipe to be processed is placed on the auxiliary structure 4, and one end of the stainless steel pipe to be processed is clamped by one of the clamping mechanisms 2; when the moving base moves towards the clamping mechanism 2 that has clamped the stainless steel pipe, it can push the clamping mechanism 2 towards the end of the support track 1 and compress the elastic support 5, thereby pushing the stainless steel pipe to be processed to move; conversely, when the moving base moves towards the middle of the support track 1, the compressed elastic support 5 resets, thereby pushing the clamping mechanism 2 that clamps the stainless steel pipe towards the middle of the support track 1, so as to push the stainless steel pipe towards the other end of the support track 1. After the elastic support 5 is completely reset, the clamping mechanism 2 is separated from the lower moving base;

[0032] When the stainless steel pipe moves from one side of the support rail 1 to the other side, the other end of the stainless steel pipe docks with the clamping mechanism 2 on the other side. At the same time, the clamping mechanism 2 contacts the moving base, and thus moves towards the end of the support rail 1 driven by the moving base, while compressing the corresponding elastic support member 5; in this way, the two sets of clamping mechanisms 2 alternately clamp the ends of the stainless steel pipe, and ensure that the stainless steel pipe continues to rotate during the movement, so as to facilitate driving the stainless steel pipe to move left and right on the auxiliary structure 4 and cooperate with the polishing mechanism 3 to complete the grinding work of the stainless steel pipe.

[0033] In order to drive the moving base to move left and right, as an embodiment of the present invention, both ends of the support rail 1 are connected to side plates 6. A worm 7 is rotatably connected between the two sets of side plates 6. One end of the worm 7 is coaxially connected to a servo motor 8 fixedly connected to the side plate 6. The moving base includes a base one 9 threadedly connected to the worm 7. One side of the base one 9 is connected to a base two 11 slidably connected to the support rail 1 through a telescopic plate 10. The worm 7 passes through the base two 11. Transmission members are installed on the sides of the two sets of base threes 13 close to each other. Rack bars 12 meshing and driving with the transmission members are respectively arranged on both sides of the bottom of the support rail 1. The clamping mechanisms 2 both include base threes 13 slidably connected to the support rail 1. Support boxes 14 are installed on the base threes 13. Pneumatic chucks are rotatably connected to the sides of the support boxes 14 close to the moving base. Tooth rings 15 corresponding to the transmission members are connected to the edges of the pneumatic chucks.

[0034] During use, the servo motor 8 drives the worm 7, thereby driving the base one 9 to move towards one end of the support rail 1. While the base one 9 moves, the telescopic plate 10 drives the base two 11 to move synchronously;

[0035] Specifically, when the servo motor 8 rotates forward, it drives the worm 7 to rotate forward, thereby driving the base one 9 to move to the right side of the support rail 1. The base one 9 pulls the base two 11 to move synchronously to the right side through the telescopic plate 10; when the base one 9 moves to the right side, it squeezes the base three 13 on the right side, thereby driving the support box 14 and the pneumatic chuck on the right side to move to the right side. When the base one 9 moves to the right side, the transmission member on the right side meshes with the rack bar 12 and the tooth ring 15 on the base three 13, thereby driving the clamping mechanism 2 on the right side to move and rotate forward; when the left end of the stainless steel pipe is polished, the servo motor 8 rotates in reverse and starts to drive the moving base to move to the left side. At this time, the base three 13 on the right side relies on the elastic support member 5 to reset and drives the base three 13 to move to the left side. At the same time, the transmission member on the right side meshes and rotates in reverse with the rack bar 12, thereby driving the clamping mechanism 2 to rotate in the reverse direction when moving to the left side;

[0036] After the moving base contacts the third base 13 on the left, it can drive the third base 13 on the left to move to the left; at the same time, it relies on the transmission parts on the left for transmission, thereby driving the clamping mechanism 2 on the left to move and rotate in the reverse direction; when the right end of the stainless steel pipe is polished, the servo motor 8 rotates forward and starts to drive the moving base to move to the right. At this time, the third base 13 on the left relies on the elastic support 5 to reset and drive the third base 13 to move to the right. At the same time, the transmission parts on the left mesh with the rack 12 and rotate forward, so as to drive the clamping mechanism 2 to rotate forward when moving to the right; in this way, the outer wall of the stainless steel pipe can be comprehensively polished.

[0037] In order to ensure the use of the transmission parts, as an embodiment of the present invention, the transmission parts include a vertical drive shaft 16. The lower end of the drive shaft 16 meshes with the rack 12 through a first gear 17. The upper end of the drive shaft 16 is provided with a second gear 18 corresponding to the toothed ring 15. Support seats 19 rotatably connected to the drive shaft 16 are installed on the sides of the third base 13.

[0038] During use, as the third base 13 moves left and right, the first gear 17 meshes with the rack 12 for transmission, thereby driving the first gear 17 to rotate. Through the drive shaft 16 for transmission, the second gear 18 is driven to rotate, thereby driving the toothed ring 15 to rotate, realizing the rotational drive of the clamping mechanism 2. It should be noted that the rotation directions of the two sets of transmission parts are opposite when moving left and right, so as to avoid conflicts when the two sets of clamping mechanisms 2 drive the stainless steel pipe.

[0039] In order to facilitate the adjustment of the distance between the first base 9 and the second base 11, as an embodiment of the present invention, the telescopic plate 10 includes a first cross plate 20 connected to the first base 9 and a second cross plate 21 connected to the second base 11. A first notch 22 is provided on the upper edge of the side of the first cross plate 20 close to the second cross plate 21. A second notch 23 corresponding to the first notch 22 is provided on the lower edge of the side of the second cross plate 21 close to the first cross plate 20. The first cross plate 20 and the second cross plate 21 are connected by bolts.

[0040] During use, if it is necessary to adjust the distance between the first base 9 and the second base 11, it is necessary to first remove the bolts, adjust the relative positions of the first notch 22 and the second notch 23, so that the positions of the first base 9 and the second base 11 meet the requirements. After that, install the bolts again to ensure the stability between the first base 9 and the second base 11;

[0041] By adjusting the distance between the first base 9 and the second base 11 to match the length of the stainless steel pipe, when ensuring that the moving base and the stainless steel pipe move synchronously, when the moving base pushes the third base 13 to move, one end of the stainless steel pipe can be inserted into the corresponding clamping mechanism 2 at the same time, so as to further ensure that the left and right movement of the stainless steel pipe can be synchronized with the movement of the clamping mechanism 2.

[0042] To ensure the use of the auxiliary structure 4, as an embodiment of the present invention, the auxiliary structure 4 includes support rollers 24 arranged on both sides of the support track 1. Both ends of the support rollers 24 are rotatably connected to brackets 25, and the lower ends of the brackets 25 are detachably connected to the side surface of the support track 1.

[0043] During use, the support rollers 24 are in contact with the outer side of the stainless steel pipe, thereby supporting the stainless steel pipe to ensure its stability. At the same time, relying on the rolling of the support rollers 24, the resistance to the rotation of the stainless steel pipe can be effectively reduced, facilitating the clamping mechanism 2 to drive the stainless steel pipe to rotate; and the surface of the support rollers 24 is smooth, enabling the stainless steel pipe to move left and right on the support rollers 24 during rotation.

[0044] To improve the flexibility of the use of the polishing mechanism 3, as an embodiment of the present invention, the polishing mechanism 3 includes a bracket 26 connected to the support track 1. The upper part of the bracket 26 is connected to a support plate 27. Linear bolt holes are distributed on the support plate 27. A convex rib 28 is integrally connected to the upper surface of the support plate 27. Above the support plate 27, a polishing motor 30 with a polishing wheel 29 is provided. The lower part of the polishing motor 30 is provided with a base, and a notch slidably matched with the convex rib 28 is provided on the base.

[0045] During use, the position of the base can be adjusted by sliding the base on the convex rib 28 of the support plate 27, thereby adjusting the position of the polishing wheel 29 to meet the grinding requirements of stainless steel pipes with different diameters; after adjustment, the base should be locked to the bolt holes on the support plate 27 through bolts to ensure the stability of the base.

[0046] To ensure the use of the elastic support member 5, as an embodiment of the present invention, the elastic support member 5 includes a piston cylinder 32 fixedly connected to the base three 13. The opening of the piston cylinder 32 faces away from the moving base. A piston plate 33 is slidably connected in the piston cylinder 32. The piston plate 33 is connected to the end of the support track 1 through a piston rod 34. A spring 35 is connected between the piston plate 33 and the inner wall of the piston cylinder 32.

[0047] During use, when the moving base squeezes the base three 13 to move and drives the piston cylinder 32 to move, when the base three 13 moves towards one end of the piston rod 34, the piston rod 34 and the piston plate 33 are squeezed into the piston cylinder 32, and the spring 35 is compressed; when the moving base moves away from the piston rod 34, the spring 35 automatically resets to drive the piston plate 33 and the piston rod 34 to move, so that the base three 13 still abuts against one side of the moving base. After the spring 35 is fully extended, the piston cylinder 32 no longer moves, and the base three 13 and the moving base are separated.

[0048] Further, the pneumatic chuck includes a hollow support shaft 36 rotatably connected to the support box 14. One end of the hollow support shaft 36 close to the moving base is connected to a support disk 37. A toothed ring 15 is installed on the edge of the support disk 37. One side of the support disk 37 close to the moving base is connected to an annular frame 38. An annular expansion pad 39 is installed on the inner wall of the annular frame 38; the annular expansion pad 39 is communicated with the inside of the hollow support shaft 36 through a pipeline. A rotary joint 40 communicated with the hollow support shaft 36 is installed at the end of the hollow support shaft 36. The rotary joint 40 is communicated with the end of the piston cylinder 32 below through a pipeline.

[0049] During use, the end of the stainless steel pipe can be inserted into the annular frame 38. When the elastic support member 5 is compressed, the air in the piston cylinder 32 is squeezed and supplied into the annular expansion pad 39. Relying on the expansion of the annular expansion pad 39, the outer side of the stainless steel pipe is clamped; and as the compression amount of the elastic support member 5 increases, more air is supplied into the annular expansion pad 39, thereby increasing the air pressure in the annular expansion pad 39 and further improving the clamping stability of the end of the stainless steel pipe, so as to facilitate driving the stainless steel pipe to rotate and pulling the stainless steel pipe to move; on the contrary, as the elastic support member 5 extends, the air pressure in the annular expansion pad 39 decreases, reducing the clamping force on the end of the stainless steel pipe, so as to facilitate the separation of the clamping mechanism 2 and the stainless steel pipe.

[0050] To avoid direct impact between the moving base and the base three 13, as an embodiment of the present invention, threaded columns 41 are threadedly connected to one side of the base three 13 close to the moving base. One side of the threaded column 41 away from the base three 13 is connected to an extrusion column 42.

[0051] During use, the distance between the extrusion column 42 and the base three 13 can be adjusted by twisting the threaded column 41, so as to conveniently adjust the distance between the moving base and the base three 13 when the moving base squeezes the base three 13 to move. This can not only facilitate ensuring that when the stainless steel pipe and the clamping mechanism 2 are inserted, the moving base can squeeze the base three 13 to move, but also reduce the impact of the moving base on the base three 13, so as to facilitate the subsequent disassembly and replacement of the extrusion column 42.

[0052] The working principle of the present invention is as follows:

[0053] First, adjust the position of the polishing mechanism 3 according to the size of the stainless steel pipe to be processed, and the auxiliary structure 4 can also be disassembled and installed to adjust the position of the auxiliary structure 4;

[0054] After that, drive the worm 7 to rotate through the servo motor 8, so as to drive the moving base to move towards one end of the support track 1, and rely on the moving base to squeeze and move one of the clamping mechanisms 2 to the end of the support track 1, and then place the stainless steel pipe to be processed on the auxiliary structure 4;

[0055] After the stainless steel pipe is placed, the driving moving base moves towards the other end of the support rail 1. The clamping mechanism 2 that is squeezed against the end of the support rail 1 relies on the elastic support member 5 to rebound and reset. During the reset process of the clamping mechanism 2, it can squeeze the end face of the stainless steel pipe, squeeze the stainless steel pipe towards the clamping mechanism 2 on the other side, and insert the stainless steel pipe into the clamping mechanism 2 on the other side. As the moving base continues to move, it can push the clamping mechanism 2 inserted with the stainless steel pipe to continue moving, and compress the elastic support member 5 below the clamping mechanism 2, squeezing the air in the piston cylinder 32 into the annular expansion pad 39 inside the clamping mechanism 2. After the annular expansion pad 39 expands, it can clamp the end of the stainless steel pipe, thus facilitating driving the stainless steel pipe to rotate and move;

[0056] When the clamping mechanism 2 clamps the stainless steel pipe through the annular expansion pad 39, the polishing mechanism 3 can be started. When the moving base moves towards the clamping mechanism 2 that has clamped the stainless steel pipe, it can push the clamping mechanism 2 towards the end of the support rail 1 and compress the elastic support member 5, thereby pushing the stainless steel pipe to be processed to move; conversely, when the moving base moves towards the middle of the support rail 1, the compressed elastic support member 5 resets, thereby pushing the clamping mechanism 2 that clamps the stainless steel pipe towards the middle of the support rail 1, thus pushing the stainless steel pipe towards the other end of the support rail 1. After the elastic support member 5 is fully reset, the clamping mechanism 2 is separated from the moving base below;

[0057] When the stainless steel pipe moves from one side of the support rail 1 to the other side, the other end of the stainless steel pipe is docked with the clamping mechanism 2 on the other side. At the same time, this clamping mechanism 2 contacts the moving base, and thus moves towards the end of the support rail 1 driven by the moving base, while compressing the corresponding elastic support member 5; in this way, the two groups of clamping mechanisms 2 alternately clamp the ends of the stainless steel pipe, and ensure that the stainless steel pipe continues to rotate during the movement, thus facilitating driving the stainless steel pipe to move left and right on the auxiliary structure 4, and cooperating with the polishing mechanism 3 to complete the grinding work of the stainless steel pipe.

[0058] It should be noted that a control valve communicating with the annular expansion pad 39 should be provided on the side of the support box 14. By exhausting air through the control valve, the annular expansion pad 39 can be conveniently contracted, thus facilitating the separation of the stainless steel pipe and the clamping mechanism 2; when the elastic support member 5 extends, air can be introduced by opening the control valve to balance the air pressure inside the elastic support member 5 with the outside world, providing guarantee for the subsequent compression and air supply of the elastic support member 5.

[0059] It should be noted that after the stainless steel pipe is polished by the polishing mechanism 3, the surface of the stainless steel can be relatively thoroughly cleaned, removing oil stains, dirt and impurities, and ensuring good adhesion of the material.

[0060] After that, the surface of the stainless steel is polished with 80 - mesh fine sand twice to remove deeper scratch oxidation layers or welding marks on the surface of the stainless steel.

[0061] Subsequently, the stainless steel pipe is passivated. The passivation is completed in 3 passes, 35 minutes for each pass. Multiple passivations can enhance wear resistance because the passivation film can reduce the direct contact between the metal surface and the external medium and lower the wear rate.

[0062] After the stainless steel pipe is passivated, a titanium plating process is carried out. The titanium plating is completed in 1 pass, and the time is 40 minutes. By controlling the time and number of passes, the uniformity and adhesion of the film layer are ensured. Titanium plating can improve the surface hardness, wear resistance and decorative properties, and at the same time endow the metal with a colored luster.

[0063] Finally, imported nano oil is used for fingerprint resistance, 40 minutes per pass. After the fingerprint-resistant spraying, a hydrophobic and oleophobic protective layer is formed, which can effectively reduce the adhesion of stains and extend the service life of the material.

[0064] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
