Description

Technical Field

[0001] This utility model relates to the field of precision stainless steel tube technology, and in particular to a semiconductor electrolytic polishing precision stainless steel tube. Background Technology

[0002] Semiconductor electropolished precision stainless steel tubes reduce fluid resistance and adsorption with ultra-high surface smoothness, eliminate contamination with high-purity substrate, and the strong corrosion-resistant passivation film formed by electropolishing withstands harsh chemical environments. They also have extremely high dimensional accuracy and can stably deliver critical media in semiconductor manufacturing, ensuring chip process yield and equipment reliability.

[0003] Existing temporary connection solutions have significant drawbacks: traditional clamp-type limiting requires manual adjustment of the pipe position, which not only results in low positioning accuracy but also makes it difficult to control clamp pressure, easily damaging the outer wall of the pipe or crushing thin-walled pipes; while ordinary sleeve-type limiting does not require clamping, it requires repeated calibration during welding; although mechanical connections such as ferrules and threads can provide temporary fixation, disassembly and assembly require tools, and the connection part can easily obstruct the welding area, resulting in incomplete welds.

[0004] In response to the technical problem of inconvenient welding between steel pipes, this application proposes a semiconductor electrolytic polishing precision stainless steel pipe. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that make welding between steel pipes inconvenient. It proposes a semiconductor electrolytic polishing precision stainless steel pipe that, by connecting and limiting the position of mounting ring one and mounting ring two, allows for the temporary connection of the steel pipe bodies. This ensures precise coaxiality of the pipes, does not obstruct subsequent welding areas, significantly shortens temporary connection time, reduces pipe material loss, and guarantees the sealing, cleanliness, and yield of subsequent welding.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A semiconductor electrolytic polishing precision stainless steel tube includes a steel tube body. Connecting rings are provided on both sides of the outer wall of the steel tube body. Pull rods are slidably connected to the inner walls of each connecting ring. The bottom ends of the pull rods are connected to the steel tube body via a snap-fit ​​assembly to fix the connecting rings to both sides of the outer wall of the steel tube body. A mounting ring one is rotatably connected to the left end of the left connecting ring. A knob is rotatably connected to the inner wall of the mounting ring one. A mounting ring two is connected to the rear end of the knob via a clamp assembly for mounting between the mounting ring one and the mounting ring two. The left end of the mounting ring two is rotatably connected to the right end of the right connecting ring.

[0008] Furthermore, the caliper assembly includes limiting grooves formed on both sides of the inner wall of the second mounting ring, and limiting blocks are slidably connected to both sides of the inner wall of the first mounting ring, the shape of the limiting blocks matching the limiting grooves.

[0009] Furthermore, a sliding frame is slidably connected to the inner wall of the mounting ring, and rotating rods are rotatably connected to both sides of the inner wall of the sliding frame, with the other end of each rotating rod rotatably connected to the inner wall of the limiting block.

[0010] Furthermore, a main bevel gear is fixedly connected to the rear end of the knob, and a secondary bevel gear is meshed with the outer wall of the main bevel gear.

[0011] Furthermore, a threaded rod is fixedly connected to the left end of the secondary bevel gear, the left end of the threaded rod is rotatably connected to the inner wall of the mounting ring, and the outer wall of the threaded rod is threadedly connected to the inner wall of the slide frame.

[0012] Furthermore, the buckle assembly includes slots formed on both sides of the outer wall of the steel pipe body, each slot having a locking block on its inner wall, each locking block having a fixing rod fixedly connected to its inner wall, each locking block having its outer wall slidably connected to the inner wall of the connecting ring, and the shape of the locking block matching the slot.

[0013] Furthermore, each of the pull rods is fixedly connected to a rotating ring at its bottom end, and the inner walls of the rotating rings are provided with sliding grooves on both sides, with the outer walls of the fixed rods slidably connected to the inner walls of the sliding grooves.

[0014] Furthermore, bolts are provided on the inner wall of each pull rod, and threaded grooves are provided on the inner wall of each connecting ring.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by connecting and limiting the installation ring one and installation ring two, the steel pipe bodies can be temporarily connected to each other, which can accurately ensure the coaxiality of the pipes, not block the subsequent welding area, greatly shorten the time of temporary connection, reduce pipe material loss, and provide a guarantee for the sealing, cleanliness and yield of subsequent welding.

[0017] 2. In this utility model, by conveniently fixing the connecting rings on both sides of the steel pipe body, it is convenient for the subsequent installation ring one and installation ring two to be connected to each other, which can quickly complete the initial assembly. When the installation ring one and installation ring two are connected later, there is no need to repeatedly adjust the position of the pipe, ensuring the coaxiality of the pipe to meet the welding requirements, improving the efficiency of temporary limit connection, and reducing the difficulty of operation and pipe loss.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 4 and Figure 5 As shown, one embodiment of this utility model provides a semiconductor electrolytic polishing precision stainless steel tube, including a steel tube body 1. Connecting rings 2 are provided on both sides of the outer wall of the steel tube body 1. A mounting ring 10 is rotatably connected to the left end of the left connecting ring 2. A knob 11 is rotatably connected to the inner wall of the mounting ring 10. A mounting ring 2 18 is rotatably connected to the right end of the right connecting ring 2. Limiting grooves 19 are formed on both sides of the inner wall of the mounting ring 2 18. Limiting blocks 17 are slidably connected to both sides of the inner wall of the mounting ring 10. The shape of the limiting blocks 17 corresponds to that of the limiting grooves 19. The inner wall of the mounting ring 10 is slidably connected to a sliding frame 15. Both sides of the inner wall of the sliding frame 15 are rotatably connected to rotating rods 16. The other end of each rotating rod 16 is rotatably connected to the inner wall of the limiting block 17. The rear end of the knob 11 is fixedly connected to a main bevel gear 12. The outer wall of the main bevel gear 12 is meshed with a secondary bevel gear 13. The left end of the secondary bevel gear 13 is fixedly connected to a threaded rod 14. The left end of the threaded rod 14 is rotatably connected to the inner wall of the mounting ring 10. The outer wall of the threaded rod 14 is threadedly connected to the inner wall of the sliding frame 15 for installation between the mounting ring 10 and the mounting ring 18.

[0027] Specifically, during disassembly, simply rotate knob 11 in the reverse direction to remove the limiting blocks 17 on both sides from the limiting groove 19. This allows for the removal of mounting ring 10 and mounting ring 18. The protrusion of mounting ring 10 matches the groove of mounting ring 18. When mounting ring 10 and mounting ring 18 are connected, the steel pipe bodies 1 are in contact with each other. By connecting and limiting mounting rings 10 and 18, the steel pipe bodies 1 can be temporarily connected. This ensures the coaxiality of the pipes, does not obstruct the subsequent welding area, significantly shortens the temporary connection time, reduces pipe material loss, and provides assurance for the sealing, cleanliness, and yield of subsequent welding.

[0028] Reference Figures 1-3 As shown, the inner wall of the connecting ring 2 is slidably connected to the pull rod 3, and the outer wall of the steel pipe body 1 is provided with multiple slots 9 on both sides. The inner wall of each slot 9 is provided with a block 6, and the inner wall of each block 6 is fixedly connected to a fixing rod 7. The outer wall of each block 6 is slidably connected to the inner wall of the connecting ring 2. The shape of the block 6 fits the slot 9. The bottom end of each pull rod 3 is fixedly connected to a rotating ring 4. The inner wall of each rotating ring 4 is provided with a sliding groove 5 on both sides. The outer wall of each fixing rod 7 is slidably connected to the inner wall of the sliding groove 5. The inner wall of each pull rod 3 is provided with a bolt 8, and the inner wall of each connecting ring 2 is provided with a threaded groove to fix the connecting ring 2 to both sides of the outer wall of the steel pipe body 1.

[0029] Specifically, when removing the connecting ring 2, first rotate the bolt 8 and then rotate the pull rod 3 backward to remove the locking blocks 6 on both sides from the slots 9. The connecting ring 2 can then be removed from the steel pipe body 1. The inner diameter of the connecting ring 2 is equal to the outer diameter of the steel pipe body 1. The depth of the slots 9 does not affect the normal use of the steel pipe body 1. By conveniently fixing the connecting ring 2 to both sides of the steel pipe body 1, it is convenient for the subsequent installation ring 10 and installation ring 2 18 to be connected to each other. The initial assembly can be completed quickly. When the installation ring 10 and installation ring 2 18 are connected, there is no need to repeatedly adjust the position of the pipe. This ensures the coaxiality of the pipe to meet the welding requirements, improves the efficiency of temporary limit connection, and reduces the difficulty of operation and pipe loss.

[0030] Working principle: First, when connecting the steel pipe bodies 1, insert the connecting ring 2 into the steel pipe body 1, align the locking block 6 with the locking groove 9, and rotate the bolt 8 to remove it from the threaded groove. Then, rotate the pull rod 3, which drives the rotating ring 4 to rotate forward, causing the fixed rod 7 to slide on the inner wall of the sliding groove 5. This pushes the locking blocks 6 on both sides inward to insert the locking block 6 into the locking groove 9. After installation, rotate the bolt 8 in the opposite direction to rotate it into the threaded groove. This allows the connecting ring 2 to be installed on both sides of the steel pipe body 1. Then, insert the installation ring 10 into the installation ring 18 of the other steel pipe body 1. After installation, rotate knob 11. Knob 11 drives main bevel gear 12 to rotate, main bevel gear 12 drives secondary bevel gear 13 to rotate, secondary bevel gear 13 drives threaded rod 14 to rotate, threaded rod 14 drives the sliding frame 15 on the outer wall to slide to the left, and drives the rotating rods 16 on both sides to rotate, pushing the limiting blocks 17 on both sides outward and inserting the limiting blocks 17 into the limiting grooves 19. This completes the connection between mounting ring 10 and mounting ring 18, and the connection between the steel pipe body 1 is completed and welded. During welding, mounting ring 10 and mounting ring 18 can be rotated to facilitate welding at different positions.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
