Description

Technical Field

[0001] The invention relates to the technical field of quartz tube welding, in particular to a pipe orifice connecting device of a double-layer quartz tube high-temperature welding machine. Background Art

[0002] Quartz tubing, a specialty industrial tubing primarily made of silicon dioxide, boasts unique properties such as high temperature resistance, corrosion resistance, high light transmittance, and excellent insulation, making it widely used in a variety of fields. A high-temperature fusion splicer utilizes a high-temperature heat source (such as an arc, flame, or laser) to melt the contact surfaces of materials (such as glass, quartz, and metals), thereby achieving a connection. It is widely used in precision manufacturing, scientific research, semiconductors, and fiber optic communications, particularly in the joining of quartz and glass tubing and the fusion splicing of optical fibers.

[0003] In the prior art, two quartz tubes are first placed on a frame, one of which is fixed and the other is movable, and then the quartz tubes are fixed. The movable frame usually includes a cylinder, a bracket and other components. The cylinder moves to push the quartz tube on the frame toward the other quartz tube, and then a heating device is used to heat and melt the tube mouths of the quartz tubes. Finally, the two melted tube mouths are fitted together to complete the connection of the tube mouths. After the quartz tubes are fixed, the staff usually wipes the tube mouths with a cloth. The tube mouths containing impurities will produce bubbles after connection, so as to avoid the impurities affecting the stability of the tube mouths after docking. Manual wiping cannot clean off more stubborn attachments, and it is easy to miss wiping. In addition, docking one pipe to another will easily increase the workload of the staff. For this reason, we propose a tube mouth connection device for a double-layer quartz tube high-temperature welding machine. Summary of the Invention

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1-8 The present invention provides a technical solution: a pipe nozzle connection device for a double-layer quartz tube high-temperature welding machine, comprising a frame 1 and further comprising:

[0037] Support rods 2, two support rods 2 are provided and symmetrically distributed and fixed on the inner side of the frame 1, a fixed bracket 3 is fixed on one side of the outer surface of the two support rods 2, and a movable bracket 4 is slidably provided on the other side of the outer surface of the two support rods 2, and a quartz tube 5 is placed on the inner wall of the fixed bracket 3 and the movable bracket 4, and an arc groove 6 is opened on both sides of the frame 1 corresponding to the fixed bracket 3 and the movable bracket 4;

[0038] There are four arc-shaped clamping rods 7, and two of them are fixedly installed on the top surface of the fixed bracket 3 and the movable bracket 4 respectively. The quartz pipe 5 is located between the arc-shaped clamping rod 7, the fixed bracket 3 and the movable bracket 4. A support plate 8 is fixed on one side of the frame 1. A cleaning unit that matches the quartz pipe 5 is provided on the surface of the support plate 8, and a dust flushing unit is provided between the support plate 8 and the movable bracket 4.

[0039] 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 by fixing bolts, thereby fixing the quartz tube 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, thereby driving the quartz tube 5 on the movable bracket 4 close to the quartz tube 5 on the fixed bracket 3.

[0040] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth noting that the cleaning unit includes:

[0041] Hydraulic rod 9, hydraulic rod 9 is fixedly installed on the top surface of support plate 8, the telescopic end of hydraulic rod 9 is fixedly installed with U-shaped connecting plate 10, the inner side of U-shaped connecting plate 10 is rotatably installed with rotating shaft 11, the outer surface of rotating shaft 11 is fixedly sleeved with roller brush 12, and the surface of support plate 8 is provided with rolling assembly matching with roller brush 12.

[0042] It is worth noting that after the quartz pipe 5 is fixed, the U-shaped connecting plate 10 is pushed downward by the hydraulic rod 9, thereby driving the roller brush 12 to move downward. During the downward movement, the roller brush 12 cleans the pipe connection when passing through the quartz pipe 5, avoiding impurities affecting the stability of the pipe connection and bringing convenience to the cleaning of the pipe.

[0043] Further as Figure 2 and Figure 4 As shown, it is worth noting that the rolling component includes:

[0044] A fixed rod 13 is provided with two fixed rods 13 and is 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 to one end of the rotating shaft 11. The first gear 15 is engaged with the rack plate 14 for transmission. A smooth area is provided at the lower end of the surface of the rack plate 14. A shaking-off component that cooperates with the roller brush 12 is provided on the bottom surface of the fixed bracket 3.

[0045] It is worth noting that 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 mouth of the quartz pipe 5.

[0046] Further as Figure 3 and Figure 6 As shown, it is worth mentioning that the ash flushing unit includes:

[0047] Push block 23, push block 23 is fixed to one side of the movable bracket 4, a fixing frame 24 is fixed to one side of the support plate 8, a connecting tube 25 is fixedly installed on the inner side of the fixing frame 24, a conduit 26 is fixed to the end of the connecting tube 25, and an air outlet hood 27 is fixed to both ends of the conduit 26. A piston 28 is slidably connected to the inside of the connecting tube 25, and a movable rod 29 is fixed to one side of the piston 28. The end of the movable rod 29 is fixed to the surface of the push block 23, and a collecting assembly is provided at the lower inner end of the frame 1.

[0048] 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 toward the fixed bracket 3, thereby pushing the piston 28 in the connecting cylinder 25 to move and compress, so that the air in the connecting cylinder 25 is ejected from the air outlet hood 27 through the conduit 26, thereby cleaning the pipe openings of the two quartz pipes 5 and blowing off the attached dust.

[0049] Further as Figure 1 and Figure 7 As shown, it is worth noting that the collection components include:

[0050] The limiting frame 30 is fixed to the inner bottom wall of the frame 1 . The inner bottom wall of the frame 1 is slidably connected with a collecting frame 31 that matches the limiting frame 30 . The collecting frame 31 is located below the pipe openings of the two quartz pipes 5 .

[0051] It is worth noting that the dust and impurities cleaned by the roller brush 12 and the air outlet hood 27 are collected by the collection frame 31, which brings convenience to the cleaning work of the staff. The limit frame 30 limits the collection frame 31 to keep the collection frame 31 stable on the frame 1.

[0052] Example 2: Based on Example 1, Figure 1 、 Figure 4 and Figure 5 As shown, it is worth noting that the shaking components include:

[0053] An L-shaped support rod 16 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. A second gear 18 is fixed to the end of the connecting shaft 17. A plurality of rubber 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. A rack rod 21 is fixed to the end of the support rod 20. The rack rod 21 is meshed with the second gear 18 for transmission;

[0054] The cylindrical block 22 is fixed to the other end of the rotating shaft 11 , and the cylindrical block 22 cooperates with the rubber swing strip 19 .

[0055] It should be noted that the hydraulic rod 9 continuously pushes the roller brush 12 downward. In the process of the roller brush 12 moving downward and leaving 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, so 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 engages with the second gear 18, so that the rack rod 21 drives the second gear 18 to rotate while continuing to descend, thereby driving the rubber swing bar 19 on the connecting shaft 17 to rotate on the L-shaped support rod 16, and the rotating rubber swing bar 19 contacts the column block 22 while rotating, thereby continuously hitting the column block 22, causing the roller brush 12 to vibrate to a certain extent, thereby shaking off impurities and debris on the roller brush 12 into the collection frame 31.

[0056] Further as Figure 7 and Figure 8 As shown, it is worth noting that the collection component also includes:

[0057] The mounting block 32 is provided with two mounting blocks 32 and is 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 card block 33. Card seats 34 are fixed on both sides of the collection frame 31. Card slots 35 are provided on the surface of the card seat 34 corresponding to the card block 33.

[0058] It is worth noting that by rotating the block 33 on the mounting block 32 and rotating the block 33 into the slot 35 of the holder 34, the collection frame 31 is limited and fixed, thereby maintaining the stability of the collection frame 31 during the collection process.

[0059] Further as Figure 1 、 Figure 3 and Figure 7 As shown, it is worth mentioning that two symmetrically distributed gripping plates 36 are fixed to the outer surface of the collection frame 31, and the gripping plates 36 facilitate the movement of the collection frame 31; four rectangularly distributed positioning blocks 37 are fixed to the lower end of the outer surface of the frame 1, and the frame 1 can be fixed by the positioning blocks 37, and the positioning blocks 37 are provided with through holes for bolts to pass through; a traction rod 38 is fixed to one side of the support plate 8, and the conduit 26 is fixed through the traction rod 38. The traction rod 38 is used to fix the conduit 26, and the conduit 26 and the air outlet hood 27 are further limited and supported by the traction rod 38.

[0060] Working principle: Place the two quartz tubes 5 to be connected on the fixed bracket 3 and the movable bracket 4 respectively, and then fix the quartz tubes 5 on the fixed bracket 3 and the movable bracket 4 through the cooperation of the arc-shaped clamping rod 7 and the bolt. When the movable bracket 4 drives the quartz tube 5 close to the other quartz tube 5, the push block 23 pushes the movable rod 29 to move toward the fixed bracket 3, thereby pushing the piston 28 in the connecting tube 25 to move and compress, so that the air in the connecting tube 25 is ejected from the outlet cover 27 through the conduit 26. When the two quartz pipes 5 are not completely fitted together, the U-shaped connecting plate 10 is pushed down by the hydraulic rod 9, thereby driving the roller brush 12 to move down. During the downward movement, the roller brush 12 cleans the pipe connection of the quartz pipe 5 when passing through the pipe connection, thereby avoiding the influence of impurities on the stability of the pipe connection. When the hydraulic rod 9 pushes the roller brush 12 to move down, the first gear 15 on the U-shaped connecting plate 10 rolls on the rack plate 14, so that the downward movement is smooth. The roller brush 12 in the middle rotates, thereby improving the cleaning effect of the roller brush 12 on the quartz pipe 5; the hydraulic rod 9 continuously pushes the roller brush 12 downward. In the process of the roller brush 12 moving downward and leaving 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, so 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 engages with the second gear 18, so that the rack rod 21 drives the second gear 18 to rotate as it continues to descend, thereby driving the rubber swing bar 19 on the connecting shaft 17 to rotate on the L-shaped support rod 16. The rotating rubber swing bar 19 contacts the column block 22 while rotating, thereby continuously hitting the column block 22, causing the roller brush 12 to vibrate to a certain extent, thereby shaking off the impurities and debris on the roller brush 12 into the collection frame 31, and by flipping the block 33 on the mounting block 32, the block 33 is stuck in the slot 35, thereby limiting and fixing the collection frame 31.

[0061] According to the above working process, it can be seen that: the quartz pipe 5 is placed on the movable bracket 4 and the fixed bracket 3, and is fixed with the arc-shaped clamping rod 7. Then, the movable bracket 4 cooperates with the dust flushing unit to blow off the dust at the pipe mouth of the quartz pipe 5, and the quartz pipe 5 is pre-cleaned. Subsequently, through the cooperation of the cleaning unit, the roller brush 12 rolls and cleans the two pipe mouths, and cleans off the dust and stains that are strongly attached, thereby promoting the stability of the subsequent quartz pipe 5 after welding. At the same time, the shaking-off 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 pipe 5, avoids the problem of missing wiping at the pipe mouth, and reduces the work intensity; the collection frame 31 is limited by the limiting frame 30, and further by the setting of the clamping block 33, the card slot 35 and other structures, the stability of the collection frame 31 on the frame 1 is improved, and then the dust and impurities cleaned by the roller brush 12 and the air outlet hood 27 are collected by the collection frame 31, which brings convenience to the cleaning of the staff.

[0062] The hydraulic rod 9 can be purchased from the market and equipped with a separate power supply. This is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
