Description

Technical Field

[0001] The present invention relates to the technical field of quartz tube welding, and specifically relates to a pipe connection device for a high-temperature welding machine of a double-layer quartz tube. Background Art

[0002] A quartz tube is a special industrial pipe made mainly of silicon dioxide, with unique properties such as high temperature resistance, corrosion resistance, high light transmittance, and good insulation, and is widely used in many fields; a high-temperature welding machine is a device that uses a high-temperature heat source (such as an electric arc, a flame, a laser, etc.) to melt the contact surfaces of materials (such as glass, quartz, metal, etc.) to achieve connection. It is widely used in fields such as precision manufacturing, scientific research, semiconductors, and optical fiber communication, and is most commonly used in the butt joint of quartz tubes and glass tubes, as well as in optical fiber welding.

[0003] In the prior art, two quartz tubes are first placed on a frame, one of the frames is fixed, and the other frame is movably arranged. Then the quartz tubes are fixed. The movably arranged frame usually includes components such as a cylinder and a bracket. Through the movement of the cylinder, the quartz tube on the frame is pushed towards the other quartz tube. Then, a heating device is used to heat and melt the pipe orifices of the quartz tubes. Finally, the two melted pipe orifices are fitted together to complete the connection of the pipe orifices; after the quartz tubes are fixed, the staff usually uses a cloth to wipe the pipe orifices. Bubbles and the like will be generated after the pipe orifices containing impurities are connected, to avoid the influence of impurities on the stability after the butt joint of the pipe orifices. However, manual wiping cannot clean stubborn attachments, and it is easy to miss wiping. Moreover, the butt joint of one pipe after another is likely to increase the working intensity of the staff. For this reason, we propose a pipe connection device for a high-temperature welding machine of a double-layer quartz tube. Summary of the Invention

Detailed implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1: Please refer to Figure 1-8 , the present invention provides a technical solution: A pipe connection device for a double-layer quartz tube high-temperature welding machine, including a frame 1, and further including: Support rods 2, two support rods 2 are provided and symmetrically distributed and fixed to the inner side of the frame 1. On one side of the outer surface of the two support rods 2, a fixed bracket 3 is fixed. On the other side of the outer surface of the two support rods 2, a movable bracket 4 is slidably arranged. The inner walls of the fixed bracket 3 and the movable bracket 4 both place quartz pipes 5. Arc-shaped grooves 6 are opened on both sides of the frame 1 corresponding to the fixed bracket 3 and the movable bracket 4; Arc-shaped clamping rods 7, four arc-shaped clamping rods 7 are provided and are respectively fixed to the top surfaces of the fixed bracket 3 and the movable bracket 4 in pairs. The quartz pipe 5 is located between the arc-shaped clamping rods 7, the fixed bracket 3 and the movable bracket 4. A cleaning unit matching the quartz pipe 5 is arranged on the surface of a support plate 8 fixed to one side of the frame 1. A dust flushing unit is arranged between the support plate 8 and the movable bracket 4.

[0020] It should be noted that the arc-shaped clamping rod 7 is connected and fixed to the fixed bracket 3 and the movable bracket 4 through fixed bolts, so as to fix the quartz pipe 5 in the fixed bracket 3 and the movable bracket 4; wherein the movable bracket 4 includes a cylinder that automatically slides on the support rod 2, so as to drive the quartz pipe 5 on the movable bracket 4 to approach the quartz pipe 5 on the fixed bracket 3.

[0021] Further, as shown in Figure 1 , Figure 2 and Figure 4 , it is worth specifically explaining that the cleaning unit includes: A hydraulic rod 9, which is fixedly installed on the top surface of the support plate 8. A U-shaped connecting plate 10 is fixedly installed at the telescopic end of the hydraulic rod 9. A rotating shaft 11 is rotatably installed inside the U-shaped connecting plate 10. A roller brush 12 is fixedly sleeved on the outer surface of the rotating shaft 11. A rolling assembly matching with the roller brush 12 is arranged on the surface of the support plate 8.

[0022] It is worth explaining that after the quartz pipeline 5 is fixed, the hydraulic rod 9 is pushed to move the U-shaped connecting plate 10 downward, thereby driving the roller brush 12 to move downward. During the downward movement, the roller brush 12 cleans the connection part of the pipe orifice when passing through the quartz pipeline 5, avoiding impurities from affecting the stability of the pipe orifice connection and bringing convenience to the cleaning of the pipe orifice.

[0023] Further, as shown in Figure 2 and Figure 4 , it is worth specifically explaining that the rolling assembly includes: Fixed rods 13. There are two fixed rods 13 which are symmetrically distributed and fixed on the surface of the support plate 8. A rack plate 14 is fixed between the ends of the two fixed rods 13. A first gear 15 is fixed at one end of the rotating shaft 11. The first gear 15 is meshed with the rack plate 14 for transmission. A smooth area is arranged at the lower end of the surface of the rack plate 14. A shaking-off assembly matching with the roller brush 12 is arranged on the bottom surface of the fixed bracket 3.

[0024] It is worth explaining that when the hydraulic rod 9 pushes the roller brush 12 to move downward, the first gear 15 on the U-shaped connecting plate 10 rolls on the rack plate 14, so that the roller brush 12 rotates during the downward movement, thereby improving the cleaning effect of the roller brush 12 on the pipe orifice of the quartz pipeline 5.

[0025] Further, as shown in Figure 3 and Figure 6 , it is worth specifically explaining that the ash flushing unit includes: A push block 23, which is fixed on one side of the movable bracket 4. A fixed frame 24 is fixed on one side of the support plate 8. A connecting cylinder 25 is fixedly installed inside the fixed frame 24. A conduit 26 is fixed at the end of the connecting cylinder 25. Air outlet hoods 27 are respectively fixed at both ends of the conduit 26. A piston 28 is slidably connected inside the connecting cylinder 25. A movable rod 29 is fixed on one side of the piston 28. The end of the movable rod 29 is fixed to the surface of the push block 23. A collecting assembly is arranged at the lower end inside the frame 1.

[0026] It should be noted that when the movable bracket 4 slides on the support rod 2 and approaches the fixed bracket 3, the push block 23 pushes the movable rod 29 to move towards the fixed bracket 3, thereby pushing the piston 28 in the connecting cylinder 25 to move and compress. As a result, the air in the connecting cylinder 25 is ejected from the air outlet cover 27 through the conduit 26, so as to clean the nozzle parts of the two quartz pipes 5, facilitating the blowing off of the attached dust.

[0027] Furthermore, as shown in Figure 1 and Figure 7 , specifically, the collection assembly includes: A limit frame 30, which is fixed to the inner bottom wall of the frame 1. A collection frame 31 that is slidably connected to the inner bottom wall of the frame 1 and cooperates with the limit frame 30 is located below the nozzle parts of the two quartz pipes 5.

[0028] It should be noted that the collection frame 31 collects the dust and impurities cleaned by the roller brush 12 and the air outlet cover 27, which brings convenience to the cleaning work of the staff. Among them, the limit frame 30 limits the collection frame 31 to keep the collection frame 31 stable on the frame 1.

[0029] Embodiment 2: On the basis of Embodiment 1, as shown in Figure 1 , Figure 4 and Figure 5 , specifically, the shaking-off assembly includes: An L-shaped support rod 16, which is fixed to one side of the bottom surface of the fixed bracket 3. One side of the L-shaped support rod 16 is rotatably connected to a connecting shaft 17. The end of the connecting shaft 17 is fixed with a second gear 18. A plurality of rubber flinging strips 19 are fixedly sleeved on the outer surface of the connecting shaft 17. A support rod 20 is fixed to the outer surface of the U-shaped connecting plate 10. The end of the support rod 20 is fixed with a rack bar 21, and the rack bar 21 is in meshing transmission with the second gear 18; A cylindrical block 22, which is fixed to the other end of the rotating shaft 11, and the cylindrical block 22 cooperates with the rubber flinging strips 19.

[0030] It should be noted that the hydraulic rod 9 continuously pushes the roller brush 12 downward. During the process of the roller brush 12 moving downward and disengaging from the quartz pipeline 5, the U-shaped connecting plate 10 drives the first gear 15 through the smooth area on the rack plate 14. Therefore, during this process, the roller brush 12 does not rotate. At the same time, the U-shaped connecting plate 10 drives the rack rod 21 to move vertically downward through the support rod 20. When the first gear 15 passes through the smooth area, the rack rod 21 meshes with the second gear 18, causing the rack rod 21 to drive the second gear 18 to rotate during the continuous downward movement, thereby driving the rubber whipping strip 19 on the connecting shaft 17 to rotate on the L-shaped support rod 16. While the rotating rubber whipping strip 19 rotates, it contacts the cylindrical block 22, thereby continuously hitting the cylindrical block 22, causing the roller brush 12 to vibrate to a certain extent, so as to shake off the impurities and debris on the roller brush 12 into the collection box 31.

[0031] Further, as Figure 7 and Figure 8 shown, specifically, the collection assembly further includes: Mounting blocks 32, there are two mounting blocks 32 and they are symmetrically distributed and fixed on the top surface of the limit frame 30. The top surface of the mounting block 32 is hinged with a clamping block 33. Clamping seats 34 are fixed on both sides of the collection box 31, and clamping grooves 35 corresponding to the clamping block 33 are opened on the surface of the clamping seat 34.

[0032] It should be noted that by rotating the clamping block 33 on the mounting block 32 and turning the clamping block 33 into the clamping groove 35 of the clamping seat 34, the collection box 31 can be limited and fixed, maintaining the stability of the collection box 31 during the collection process.

[0033] Further, as Figure 1 、 Figure 3 and Figure 7 shown, specifically, two symmetrically distributed grip plates 36 are fixed on the outer surface of the collection box 31, and the grip plates 36 facilitate the handling of the collection box 31; four rectangularly distributed positioning blocks 37 are fixed on the lower end of the outer surface of the frame 1, and the frame 1 can be fixed through the positioning blocks 37. Through holes for bolts to pass through are opened on the positioning blocks 37; a traction rod 38 is fixed on one side of the support plate 8, and the conduit 26 is fixedly penetrated through the traction rod 38. The traction rod 38 is used for fixing the conduit 26, and further limits and supports the conduit 26 and the air outlet cover 27 through the traction rod 38.

[0034] Working principle: Place the two quartz pipes 5 to be connected on the fixed bracket 3 and the movable bracket 4 respectively. Then, through the cooperation of the arc-shaped clamping rod 7 and the bolt, fix the quartz pipe 5 on the fixed bracket 3 and the movable bracket 4. When the movable bracket 4 drives the quartz pipe 5 to approach another quartz pipe 5, the push block 23 pushes the movable rod 29 to move towards the fixed bracket 3, thereby pushing the piston 28 in the connecting cylinder 25 to move and compress. As a result, the air in the connecting cylinder 25 is ejected from the air outlet cover 27 through the conduit 26, so as to clean the pipe orifices of the two quartz pipes 5, facilitating the blowing off of the attached dust. When the two quartz pipes 5 are not fully fitted, the hydraulic rod 9 pushes the U-shaped connecting plate 10 downward, thereby driving the roller brush 12 to move downward. During the downward movement, the roller brush 12 cleans the connection of the pipe orifices when passing through the quartz pipe 5, avoiding the influence of impurities on the stability of the pipe orifice connection. When the hydraulic rod 9 pushes the roller brush 12 downward, the first gear 15 on the U-shaped connecting plate 10 rolls on the rack plate 14, causing the roller brush 12 to rotate during the downward movement, thereby improving the cleaning effect of the roller brush 12 on the pipe orifice of the quartz pipe 5; the hydraulic rod 9 continuously pushes the roller brush 12 downward. During the process of the roller brush 12 moving downward and disengaging from the quartz pipe 5, the U-shaped connecting plate 10 drives the first gear 15 to pass through the smooth area on the rack plate 14. Therefore, the roller brush 12 does not rotate during this process. At the same time, the U-shaped connecting plate 10 drives the rack rod 21 to move vertically downward through the support rod 20. When the first gear 15 passes through the smooth area, the rack rod 21 meshes with the second gear 18, causing the rack rod 21 to drive the second gear 18 to rotate during the continuous downward movement, thereby driving the rubber flapper 19 on the connecting shaft 17 to rotate on the L-shaped support rod 16. While the rotating rubber flapper 19 rotates, it contacts the cylindrical block 22, thereby continuously hitting the cylindrical block 22, causing the roller brush 12 to vibrate to a certain extent, so as to shake off the impurities and debris on the roller brush 12 into the collection box 31. By flipping the block 33 on the mounting block 32, the block 33 is stuck in the card slot 35, thereby limiting and fixing the collection box 31.

[0035] According to the above working process, it can be known that the quartz pipeline 5 is placed on the movable bracket 4 and the fixed bracket 3, and fixed by using the arc-shaped clamping rod 7. Then, through the cooperation of the movable bracket 4 and the ash flushing unit, the dust at the nozzle of the quartz pipeline 5 is blown off, and the quartz pipeline 5 is pre-cleaned. Subsequently, through the cooperation of the cleaning unit, the roller brush 12 rolls and cleans the two nozzles, and the dust and stains with strong adhesion are cleaned off, which promotes the stability of the subsequent welded quartz pipeline 5. At the same time, the shaking component shakes off the dust and impurities on the cleaned roller brush 12, reduces the scattering of impurities on the cleaned roller brush 12, improves the welding quality of the quartz pipeline 5, avoids the problem of missed wiping at the nozzle, and reduces the working intensity. The collecting frame 31 is limited by the limiting frame 30, and further, through the settings of structures such as the clamping block 33 and the clamping groove 35, the stability of the collecting frame 31 on the frame 1 is improved. Then, the collecting frame 31 collects the dust and impurities cleaned by the roller brush 12 and the air outlet cover 27, which brings convenience to the cleaning of the staff.

[0036] The hydraulic rod 9 can be purchased on the market and is equipped with a power supply separately. It is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
