Abstract
Description
Technical Field
[0001] This utility model relates to the field of stainless steel pipe processing technology, specifically a semiconductor-grade stainless steel pipe surface treatment device. Background Technology
[0002] Semiconductor-grade stainless steel tubing is a special type of stainless steel tubing specifically designed for the semiconductor industry. It possesses excellent corrosion resistance and processing performance, meeting the requirements of semiconductor manufacturing processes for components that come into direct contact with high-purity gases and liquids, such as valves, ultra-high-purity products, and gas control components. Surface treatments for semiconductor-grade stainless steel tubing include mechanical polishing, electrolytic polishing, and chemical polishing. Mechanical polishing uses polishing wheels or belts with abrasive particles in the polishing compound to grind the surface of the stainless steel tubing, achieving a smooth finish. In grinding the inner wall of the stainless steel tubing, some equipment uses two rubber rollers to drive the tubing to rotate, and a grinding block extends into the tubing for grinding. During grinding, debris accumulates on both sides of the grinding block, but due to the horizontal limitation of the stainless steel tubing, the debris inside is difficult to expel on its own. The debris mixes with the polishing compound, affecting the grinding effect. The accumulation and splashing of debris during rotation results in significant dust, and when the stainless steel tubing is removed after grinding, debris easily scatters outside the unit, causing a dirty working environment and inconvenience.

[0035] 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.
[0036] Please see Figure 1-5 In this embodiment of the present invention, a semiconductor-grade stainless steel tube surface treatment device includes a limiting seat 10, multiple drive rollers 11 rotatably connected to the top of the limiting seat 10, a positioning plate 12 fixedly connected to the top of the limiting seat 10, an mounting tube 14 slidably connected to the top of the limiting seat 10, a limiting tube 141 fixedly connected to one end of the mounting tube 14, a plurality of grinding blocks 142 slidably connected to one end of the limiting tube 141, a limiting module 13 disposed on the top of the limiting seat 10, capable of positioning the stainless steel tube body 20, and a control module 15 disposed inside the limiting seat 10, capable of driving the mounting tube 14 and the grinding blocks 142.
[0037] Specifically, multiple grinding blocks 142 are slidably connected to one end of the limiting tube 141, allowing the grinding blocks 142 to move and create space with the inner wall of the stainless steel tube body 20. Two drive rollers 11 limit the stainless steel tube body 20 to an inclined state, facilitating the timely discharge of grinding waste inside the stainless steel tube body 20, reducing the impact of waste on the grinding of the inner wall of the stainless steel tube body 20. The waste can be collected uniformly through the sewage trough 101, making the working environment cleaner and more convenient to use.
[0038] Example 1
[0039] like Figure 1-4 As shown, in this embodiment, a protective shell 111 is fixedly connected to the top of the limiting seat 10. One end of the drive roller 11 passes through the protective shell 111 and extends into it. A gear 112 is fixedly sleeved on one end of the protective shell 111. A motor 113 is fixedly connected to the inner bottom surface of the protective shell 111. A gear 114 is fixedly sleeved on the output end of the motor 113. Both gears 112 mesh with gear 114. The limiting module 13 includes a limiting frame 131. Multiple positioning rods 132 are provided and fixedly connected to the top of the limiting seat 10. Multiple positioning rods 132 pass through the limiting frame 131 and are slidably connected to it. Multiple shafts 133 are provided and rotatably connected to the bottom of the limiting frame 131. Multiple rollers 134 are provided and fixedly sleeved on the outer wall of the shaft 133. Multiple hydraulic rods 135 are provided and fixedly connected to the top of the limiting seat 10. The output end of the hydraulic rod 135 is fixedly connected to the limiting frame 131.
[0040] In this embodiment, the internal transmission components are protected by the protective shell 111. The starting motor 113 drives the gear 114 to rotate, and the gear 114 drives the two gears 112 and the drive roller 11 to rotate synchronously and in the same direction, thereby driving the stainless steel tube body 20 placed between the two drive rollers 11 to rotate. The drive roller 11 is provided with a rubber layer on the outside to increase the friction between it and the stainless steel tube body 20, so as to stabilize the rotation of the stainless steel tube body 20. With the help of multiple grinding blocks 142, the inner wall of the stainless steel tube body 20 can be ground and polished. The limiting frame 131 is slidably limited by multiple positioning rods 132. After the stainless steel tube body 20 is placed between the two limiting seats 10, the positioning plate 12 contacts the bottom end of the stainless steel tube body 20 to prevent the stainless steel tube body 20 from sliding down. The starting positioning rod 132 drives the two limiting frames 131 to move down, and the multiple rollers 134 contact the outer wall of the stainless steel tube body 20, thereby preventing the stainless steel tube body 20 from shifting its position during rotation.
[0041] like Figure 2-5 As shown, in this embodiment, a plurality of insert blocks 143 are fixedly connected to the inner wall of the mounting tube 14, and a plurality of docking blocks 144 are fixedly connected to the inner wall of the limiting tube 141. The insert blocks 143 can be movably engaged with the docking blocks 144. A fixing screw 145 is provided on the outer wall of the limiting tube 141. The fixing screw 145 can pass through the docking blocks 144 and be screwed into the adjacent insert blocks 143. A drain trough 101 is provided inside the limiting seat 10, and a guide bucket 102 is fixedly connected to the top of the limiting seat 10.
[0042] In specific implementation, when the installation tube 14 and the limiting tube 141 are connected, the two inserts 143 are aligned with the connecting block 144 and inserted, and then the two fixing screws 145 are tightened and inserted into the inserts 143 to prevent the inserts 143 from coming loose on their own, thereby reinforcing the connection between the installation tube 14 and the limiting tube 141. The installation tube 14 and the limiting tube 141 can be disassembled, which makes it convenient to replace multiple grinding blocks 142. After prolonged use, the grinding blocks 142 will experience more wear and tear and need to be replaced and maintained. The waste debris leaking from the lower end of the stainless steel pipe body 20 can be guided and recycled through the drain trough 101. The guide bucket 102 expands the collection area at the top of the drain trough 101 to prevent debris from scattering on the top of the limiting seat 10.
[0043] Example 2
[0044] Based on Embodiment 1, in order to drive multiple grinding blocks 142 to automatically create space with the inner wall of the stainless steel tube body 20, the grinding waste can be discharged automatically.
[0045] like Figure 5As shown, in this embodiment, the control module 15 includes a fixed frame 151, which is slidably connected between the two outer walls of the limiting seat 10. The mounting tube 14 is fixedly connected to the fixed frame 151. A connecting plate 152 is fixedly connected between the two ends of the fixed frame 151, passing through the limiting seat 10 and slidably connected thereto. Multiple hydraulic rods 153 are provided and fixedly connected to the inner wall of the limiting seat 10. The output end of the hydraulic rod 153 is fixedly connected to the connecting plate 152. The limiting tube 141... A positioning tube 159 is fixedly connected to the inner wall of the positioning tube 159. Multiple rectangular rods 154 are slidably connected inside the positioning tube 159. One end of the rectangular rod 154 passes through the limiting tube 141 and is fixedly connected to the adjacent grinding block 142. The other end of the rectangular rod 154 is fixedly connected to a round block 156. A spring 155 is fixedly connected between the rectangular rod 154 and the outer wall of the positioning tube 159. A hydraulic rod 157 is fixedly connected to the inner wall of the limiting tube 141. A guide block 158 is fixedly sleeved on the output end of the hydraulic rod 157.
[0046] In specific implementation, the limiting seat 10 limits the fixing frame 151, thereby achieving the sliding limitation of the mounting tube 14. However, the mounting tube 14 is not horizontal; both the drive roller 11 and the mounting tube 14 maintain a 20-degree inclination, facilitating the sliding and discharge of waste inside the stainless steel tube body 20. Activating the two hydraulic rods 153 drives the fixing frame 151 to move laterally via the connecting plate 152, thus driving the mounting tube 14 to move. This causes the limiting tube 141 and multiple grinding blocks 142 to extend into different positions inside the stainless steel tube body 20, polishing different areas of the inner wall of the stainless steel tube body 20. The positioning tube 159 then positions multiple rectangular... The limiting position of rod 154 achieves sliding limitation of multiple grinding blocks 142. When the guide block 158 is not in contact with multiple round blocks 156, multiple springs 155 are in their original state, and multiple grinding blocks 142 are a certain distance from the inner wall of stainless steel tube body 20. This space facilitates the discharge of waste. The hydraulic rod 157 is activated to drive the guide block 158 to move. The guide block 158 pushes the round blocks 156 to drive the rectangular rod 154 to move, compressing the springs 155. Multiple grinding blocks 142 move and approach the inner wall of stainless steel tube body 20 until they contact the inner wall of stainless steel tube body 20, thereby facilitating the grinding of the inner wall of stainless steel tube body 20.
