Description

Technical Field

[0001] This utility model relates to the field of pipe inner wall polishing technology, specifically a mechanism for polishing the inner wall of stainless steel pipes used in pneumatic components. Background Technology

[0002] Stainless steel tubing for pneumatic components is a high-precision, high-performance seamless stainless steel tube specifically designed for manufacturing core components of pneumatic systems (such as cylinders and valve bodies). It requires extremely high levels of smoothness, cleanliness, and dimensional consistency of the inner wall of the stainless steel tube to ensure sealing performance, reduce flow resistance, and extend service life.

[0003] Existing polishing mechanisms typically fix only one side of the grinding head when polishing the inner wall of stainless steel pipes, and insert the unfixed end into one end of the stainless steel pipe. Then, they gradually move the head to polish the inner wall of the stainless steel pipe. However, in actual use, since the grinding head usually rotates at high speed, it is prone to vibration when only one side of the grinding head is fixed, which affects the polishing of the inner wall of the stainless steel pipe.

The fixed components include a lifting assembly, a positioning assembly, two clamping assemblies, and multiple positioning wheels 3. The positioning assembly is fixedly installed on the top of the base plate 20, the lifting assembly is installed on the top of the base plate 20 and is located on one side of the positioning assembly, each clamping assembly is installed above the positioning assembly, and multiple positioning wheels 3 are fixedly installed on the two clamping assemblies respectively. The stainless steel tube 1 is installed on the positioning assembly. It should be noted that the outer wall of each positioning wheel 3 is covered with anti-slip rubber. The stabilizing component includes a connecting block 34 and a support assembly. The support assembly is located on the side of the positioning assembly away from the moving assembly and is located on the top of the base plate 20. The connecting block 34 is located on the support assembly.

[0024] like Figures 1-7As shown, the moving assembly includes a first motor 4, a vertical plate 5, a lead screw 6, a slider 7, a connecting plate 8, a first guide rail 10, a first sliding plate 11, and two mounting plates 9. Each mounting plate 9 is fixedly mounted on the top of the base plate 20. The lead screw 6 is rotatably mounted between the two mounting plates 9. The vertical plate 5 is fixedly mounted on one side of one of the mounting plates 9. The first motor 4 is fixedly mounted on one side of the vertical plate 5, and one end of the lead screw 6 is fixedly connected to the output end of the first motor 4. The guide rail 10 is fixedly mounted on the top of the base plate 20. The first sliding plate 11 is slidably mounted inside the guide rail 10. The connecting plate 8 is fixedly mounted on one side of the first sliding plate 11. The slider 7 is fixedly mounted on the bottom of the connecting plate 8, and the slider 7 is threadedly connected to the lead screw 6. When the inner wall of the stainless steel pipe 1 needs to be polished, the controller controls the first motor 4 to work, the first motor 4 drives the lead screw 6 to rotate, the lead screw 6 drives the slider 7 on the outer wall to move, the slider 7 drives the connecting plate 8 above to move, and the connecting plate 8 drives the first slide plate 11 on one side to move on the first guide rail 10, so that the polishing head 2 is close to the stainless steel pipe 1, which facilitates the polishing of the stainless steel pipe 1.

[0025] like Figures 1-7 As shown, the rotating assembly includes a fixed plate 12, a second motor 13, a mounting base 14, a rotating rod 15, a rotating roller 16, a first rotating wheel 17, a second rotating wheel 18, and a rotating belt 19.

When the polishing head 2 approaches the stainless steel tube 1, the controller activates the second motor 13, which in turn drives the first rotating wheel 17 to rotate. The first rotating wheel 17 then drives the rotating belt 19, which in turn drives the second rotating wheel 18, which in turn drives the rotating rod 15 and the rotating roller 16 to rotate. The rotating rod 15 drives the polishing head 2 at one end to rotate. The rapid rotation of the polishing head 2, combined with the movement of the moving components, polishes the inner wall of the stainless steel tube 1.

[0026] like Figures 1-7As shown, the positioning assembly includes two fixed seats 21 and two positioning rollers 22. Each fixed seat 21 is fixedly installed on the top of the base plate 20, and each positioning roller 22 is fixedly installed between the two fixed seats 21. The stainless steel tube 1 is located above the two positioning rollers 22. It should be noted that the outer wall of each positioning roller 22 is provided with anti-slip rubber. When it is necessary to fix the stainless steel tube 1, the stainless steel tube 1 is placed between two positioning rollers 22 and positioned by the groove between the two positioning rollers 22 to prevent the stainless steel tube 1 from shifting. At the same time, the contact distance between the two positioning rollers 22 and the stainless steel tube 1 is relatively smooth, which can effectively avoid friction during the polishing process of the stainless steel tube 1, thus avoiding damage to the stainless steel tube 1.

[0027] like Figures 1-7 As shown, the lifting assembly includes a support frame 23, a horizontal plate 24, a cylinder 25, a lifting plate 26, two guide rods 27, two guide grooves 28, two sealing plates 41, and two support rods 29.

The horizontal plate 24 is fixedly installed between the two support rods 29. The cylinder 25 is inserted into the top of the horizontal plate 24. The lifting plate 26 is installed below the horizontal plate 24, and the lifting plate 26 is fixedly connected to the output end of the cylinder 25. Each guide groove 28 is opened on the top of a support rod 29. Each guide rod 27 is slidably installed in a guide groove 28, and the bottom of each guide rod 27 is fixedly connected to the lifting plate 26. Each sealing plate 41 is fixedly installed at the end of a guide rod 27 away from the lifting plate 26. When it is necessary to fix the stainless steel pipe 1 after positioning, the controller controls the cylinder 25 to extend and retract, which drives the lifting plate 26 to descend. The lifting plate 26 drives the multiple positioning wheels 3 below to descend and work with the two positioning rollers 22 to fix the stainless steel pipe 1. When the lifting plate 26 is raised and lowered, it will drive the two guide rods 27 to rise and fall at the same time. The guide rods 27 guide the movement of the lifting plate 26.

[0028] like Figures 1-7 As shown, each clamping assembly includes a fixing rod 30, a fixing block 31, two positioning plates 32 and two fixing shafts 33. The fixing rod 30 is fixedly installed at the bottom of the lifting plate 26, the fixing block 31 is fixedly installed at the bottom of the fixing rod 30, the two positioning plates 32 are respectively fixedly installed on both sides of the fixing block 31, each fixing shaft 33 is fixedly installed on the two positioning plates 32, and each positioning wheel 3 is fixedly installed at one end of a fixing shaft 33. When the lifting plate 26 descends, it will drive the two fixed rods 30 to descend. The fixed rods 30 will drive the fixed block 31 and the positioning plate 32 to descend. The positioning plate 32 will drive the fixed shaft 33 to descend, thereby driving multiple positioning wheels 3 to descend and press against the upper part of the stainless steel tube 1. Together with the two positioning rollers below, the stainless steel tube 1 will be positioned and fixed. At the same time, the rubber structure on the surface of the positioning wheel 3 can prevent damage to the outer wall of the stainless steel tube 1. It should be noted that in actual use, an appropriate number of clamping components should be selected according to the length of the stainless steel pipe 1, so as to install an appropriate number of positioning wheels 3, so as to ensure a stable positioning effect for stainless steel pipes 1 of different lengths.

[0029] like Figures 1-7 As shown, the support assembly includes a second guide rail 35, a second slide plate 36, a stabilizing plate 37, a stabilizing rod 38, a slot 39, and a spring 40. The slot 39 is located at one end of the polishing head 2. The second guide rail 35 is fixedly mounted on the top of the base plate 20. The second slide plate 36 is slidably mounted on the second guide rail 35. The spring 40 is located inside the second guide rail 35, and both ends of the spring 40 are fixedly connected to the second guide rail 35 and the second slide plate 36, respectively. The stabilizing plate 37 is fixedly mounted on the top of the second slide plate 36. The stabilizing rod 38 is fixedly mounted on one end of the stabilizing plate 37. The connecting block 34 is rotatably connected to the end of the stabilizing rod 38 away from the stabilizing plate 37. The connecting block 34 passes through the stainless steel tube 1 and engages with the slot 39. It should be noted that in the initial state, the spring 40 is in its natural state, and the second slide plate 36 slides inside the second guide rail 35 and is located on the side closer to the polishing head 2. When the inner wall of the stainless steel pipe 1 needs to be polished, the groove 3 on one side of the polishing head 2 is connected to one end of the connecting block 34. This allows the polishing head 2 to be supported on both sides when it rotates, preventing the polishing head 2 from shaking during rotation and affecting the polishing effect. At the same time, when the polishing head 2 moves, it will drive the connecting block 34 to move through the groove 39. The connecting block 34 will always be in contact with the groove 39 under the action of the spring.
