Abstract
Description
Technical Field
[0001] This invention relates to the field of radiator welding technology, specifically a welding device for radiators used in engineering machinery. Background Technology
[0002] Construction machinery generates heat during operation, so radiators are installed to dissipate heat. A construction machinery radiator includes a main pipe and multiple branch pipes welded to it. The main pipe collects the heat dissipation medium flowing through the branch pipes. The branch pipes are roughly T-shaped with the main pipe, and the circumferential seam between them is roughly annular. In related technologies, when welding an annular weld, the welding device first welds the first half of the annular weld, then welds the second half to complete the entire annular weld. However, welding the second half can easily cause the previously welded first half to be reheated, affecting the welding quality of the first half. Therefore, when welding an annular weld, it is necessary to weld both the first and second halves simultaneously. When welding the main pipe, it needs to be welded to multiple branch pipes. However, when welding multiple branch pipes to the main pipe, the main pipe is easily affected by external forces, causing it to shake and deflect, which affects the welding effect. Therefore, we have proposed a welding device for radiators of engineering machinery. Summary of the Invention
[0003] To solve the above-mentioned technical problems, the present invention provides a welding device for radiators of engineering machinery, including a square base, a side-pressure fixing mechanism fixedly connected to the top of the square base, a vertical electric slide rail fixedly connected to the top of the square base, an adjustable tube clamping mechanism slidably connected to the inner side of the vertical electric slide rail, vertical fixing plates fixedly connected to both sides of the vertical electric slide rail, a hanging electric slide rail fixedly connected to the top of the vertical electric slide rail, a bottom plate slidably connected to the bottom of the hanging electric slide rail, and an electric welding arm fixedly connected to the bottom of the bottom plate. The side pressure fixing mechanism includes a circular concave shell. Two circular concave shells clamp the ends of the main pipe from both ends to prevent the main pipe from shaking or deflecting due to external force during the butt welding operation of the branch pipe. An annular electric slide rail is sleeved on the outside of the circular concave shell and rotatably connected to it. An auxiliary drive component is fixedly connected to the outside of the annular electric slide rail. Two vertical electric slide rails are provided, and the two vertical electric slide rails are respectively distributed on both sides of the side pressure fixing mechanism. Two electric welding arms are provided, and the two electric welding arms are symmetrically distributed on the bottom of the bottom slide plate. Two auxiliary drive components are provided, and the two auxiliary drive components are symmetrically distributed on both sides of the annular electric slide rail. The bottom of the auxiliary drive component is fixedly connected to the top of the square base. A straightening corner block is fixedly connected to the top of the annular electric slide rail, and an arc-shaped grinding block is fixedly connected to the inner side of the circular concave shell. The arc-shaped grinding block is used to grind the end face of the pre-fixed main pipe flat by setting the arc-shaped grinding block on the inner wall of the circular concave shell, so as to prevent the end face of the main pipe from being uneven when it is fixed, which would cause the whole pipe to be tilted and affect the welding effect of the branch pipe. An arc-shaped through hole is opened on the inner side of the circular concave shell. Multiple arc-shaped through holes are opened on the inner wall of the circular concave shell to facilitate the timely discharge of grinding debris, preventing the grinding debris from accumulating on the inner wall of the circular concave shell and affecting the fixing and clamping effect of the main pipe. A straightening arc block is fixedly connected to the outer side of the circular concave shell. The setting of the straightening arc block and the straightening corner block makes the annular weld of the main pipe in a position directly facing upward, preventing the difficulty in accurately adjusting the annular weld to the position directly facing upward after rotating and grinding the main pipe, which would affect the welding effect. There are three arc-shaped grinding blocks, and the three arc-shaped grinding blocks are distributed inside the circular concave shell. There are three arc-shaped through holes, and the three arc-shaped through holes are located inside the circular concave shell.
[0004] Furthermore, the auxiliary drive assembly includes a threaded rod, with fixed angle plates fixedly connected to both ends of the threaded rod. A threaded sleeve block is fitted and threadedly connected to the outer side of the threaded rod. Arc-shaped brushes are fixedly connected to both sides of the threaded sleeve block. As the threaded sleeve block moves, the arc-shaped brushes clean the outer surface of the threaded rod, preventing dust and welding slag from affecting the threaded fit between the threaded sleeve block and the threaded rod. A second annular electric slide rail is fitted and rotatably connected to the outer side of the threaded sleeve block. A side connecting square plate is fixedly connected to the outer side of the second annular electric slide rail. By simultaneously setting side connecting square plates on both sides of the first annular electric slide rail, the rotation of the second annular electric slide rail is limited, preventing the threaded sleeve block from rotating due to the threaded fit between the threaded sleeve block and the threaded rod when the second annular electric slide rail is not limited. A slanted scraper is fixedly connected to one side of the second annular electric slide rail. When the slanted scraper moves together with the threaded sleeve block, it scrapes and cleans the top surface of the square base, preventing excessive welding slag from accumulating on the square base after prolonged welding and adhering to its surface when the main pipe rotates, thus affecting the subsequent welding effect. The slanted surface of the slanted scraper causes the pushed welding slag to move towards the fixed angle plate, preventing some of the pushed welding slag from accumulating near the side of the vertical electric slide rail and being difficult to handle. The side connecting square plate is fixedly connected to the outer side of the first annular electric slide rail on the side away from the second annular electric slide rail. The bottom of the fixed angle plate is fixedly connected to the top of the square base. Multiple threaded sleeve blocks are provided, and the multiple threaded sleeve blocks are symmetrically distributed on the threaded long rod. Multiple arc-shaped brushes are provided, and the multiple arc-shaped brushes are distributed on both sides of the threaded sleeve blocks.
[0005] Furthermore, the adjustable pipe clamping mechanism includes an inner sliding plate with a rectangular through hole on one side. An annular sleeve is slidably connected to the inner wall of the rectangular through hole. The sliding engagement between the annular sleeve and the rectangular through hole allows for adjustment of the branch pipe position to accommodate different docking positions. This prevents the branch pipe from being difficult to adjust and affecting the welding process when the annular welding docking position of the main pipe changes. An external angle plate is fixedly connected to the outer side of the annular sleeve. A fixed through rod is passed through and fixedly connected to the top of the external angle plate. A curved pressure plate is sleeved and slidably connected to the outer side of the fixed through rod. A return spring is fixedly connected to the inner side of the curved pressure plate. The extension force of the return spring pushes the curved pressure plate into tight contact with the inner wall of the rectangular through hole to clamp the annular pipe. The branch pipes within the sleeve are fixed in position to prevent them from shifting relative to the annular weld seam due to external forces during welding operations, thus affecting the welding effect. The adjustable pipe clamping mechanism is easily disassembled and installed via the telescopic pushing and fixing of two curved pressure plates and a return spring. This prevents the difficulty in adjusting the branch pipes to adapt to changes in the number of branch pipes to be welded to complete the welding process. One side of the inner sliding plate is slidably connected to the inner side of the vertical electric slide rail. Multiple annular sleeves are provided, distributed on the inner wall of the rectangular through hole. Multiple external angle plates are provided, symmetrically distributed on the outer side of the annular sleeves. Multiple curved pressure plates are provided, symmetrically distributed at both ends of the return spring.
[0006] This invention provides a welding device for radiators of engineering machinery. It has the following advantages: 1. The welding device for the radiator of this engineering machinery has two circular concave shells that clamp the ends of the main pipe from both ends to prevent the main pipe from shaking or deflecting due to external forces during the butt welding of branch pipes, thus affecting the welding effect. The arc-shaped brush cleans the outer surface of the threaded rod as the threaded sleeve moves, preventing dust and welding slag from adhering to the outer surface of the threaded rod and affecting the thread fit between the threaded sleeve and the threaded rod. The sliding fit between the annular sleeve and the rectangular through hole allows the adjustment of the branch pipe position to adapt to different butt welding positions, preventing the branch pipe from being difficult to adjust when the annular welding butt welding position of the main pipe changes, thus affecting the welding process.
[0007] 2. The welding device for the radiator of this engineering machinery is equipped with a side-pressure fixing mechanism. An arc-shaped grinding block is installed on the inner wall of a circular concave shell to grind the pre-fixed main pipe end face flat, preventing unevenness during fixing and ensuring the overall tilt, which would affect the butt welding effect of the branch pipes. Multiple arc-shaped through holes are opened on the inner wall of the circular concave shell to facilitate the timely discharge of grinding debris, preventing debris accumulation and affecting the fixing and clamping effect of the main pipe. The setting of the correction arc block and correction corner block ensures that the annular weld of the main pipe is in a directly upward position, preventing difficulty in accurately adjusting the annular weld to the directly upward position after rotating and grinding the main pipe, thus affecting the welding effect. Two circular concave shells respectively clamp the ends of the main pipe from both ends, preventing the main pipe from shaking or deflecting due to external forces during the butt welding operation of the branch pipes, thus preventing the welding effect from being affected.
[0008] 3. The welding device for the radiator of this engineering machinery is equipped with an auxiliary drive component. The arc-shaped brush cleans the outer surface of the threaded rod as the threaded sleeve moves, preventing dust and welding slag from affecting the threaded engagement between the threaded sleeve and the threaded rod. Side connecting square plates are set on both sides of the annular electric slide rail one to limit the rotation of the annular electric slide rail two, preventing the threaded sleeve from rotating due to the threaded engagement between the threaded sleeve and the threaded rod when the annular electric slide rail two is not limited. The inclined scraper moves with the threaded sleeve to scrape the top surface of the square base, preventing excessive welding slag from accumulating on the square base after long-term welding and adhering to its surface when the main pipe rotates, affecting the subsequent welding effect. The inclined surface of the inclined scraper causes the pushed welding slag to move towards the fixed angle plate, preventing some of the pushed welding slag from accumulating near the vertical electric slide rail side and being difficult to handle.
[0009] 4. The welding device for the radiator of this engineering machinery is equipped with an adjustable pipe clamping mechanism. The position of the branch pipe is adjusted by the sliding fit between the annular sleeve and the rectangular through hole to adapt to different docking positions. This prevents the branch pipe from being difficult to adjust when the annular welding docking position of the main pipe changes, thus affecting the welding process. The extension force of the return spring pushes the curved pressure plate to make tight contact with the inner wall of the rectangular through hole to fix the position of the branch pipe in the annular sleeve. This prevents the branch pipe from being relatively offset from the annular weld seam by external force during the welding operation, thus affecting the welding effect. The extension and pressing of the two curved pressure plates and the return spring facilitate the disassembly and installation of the adjustable pipe clamping mechanism, preventing the branch pipe from being difficult to adjust to complete the welding process when the number of branch pipes to be welded to the main pipe changes.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0013] Please see Figures 1-6 The present invention provides a welding device for radiators of engineering machinery, including a square base 1, a side pressure fixing mechanism 2 fixedly connected to the top of the square base 1, a vertical electric slide rail 3 fixedly connected to the top of the square base 1, an adjustable tube clamping mechanism 4 slidably connected to the inner side of the vertical electric slide rail 3, vertical fixing plates 5 fixedly connected to both sides of the vertical electric slide rail 3, a hanging electric slide rail 6 fixedly connected to the top of the vertical electric slide rail 3, a bottom plate 7 slidably connected to the bottom of the hanging electric slide rail 6, and an electric welding arm 8 fixedly connected to the bottom of the bottom plate 7. The side pressure fixing mechanism 2 includes a circular concave shell 201, an annular electric slide rail 202 is sleeved on and rotatably connected to the outer side of the circular concave shell 201, and an auxiliary drive assembly 203 is fixedly connected to the outer side of the annular electric slide rail 202. There are two vertical electric slide rails 3, which are respectively distributed on both sides of the side pressure fixing mechanism 2. There are two electric welding arms 8, which are symmetrically distributed on the bottom of the bottom slide plate 7. There are two auxiliary drive components 203, and the two auxiliary drive components 203 are symmetrically distributed on both sides of the annular electric slide rail 202. The bottom of the auxiliary drive component 203 is fixedly connected to the top of the square base 1. A straightening corner block 204 is fixedly connected to the top of the annular electric slide rail 202, an arc-shaped grinding block 205 is fixedly connected to the inner side of the circular concave shell 201, an arc-shaped through hole 206 is opened on the inner side of the circular concave shell 201, and a straightening arc block 207 is fixedly connected to the outer side of the circular concave shell 201. There are three arc-shaped grinding blocks 205, and the three arc-shaped grinding blocks 205 are distributed inside the circular concave shell 201. There are three arc-shaped through holes 206, and the three arc-shaped through holes 206 are located inside the circular concave shell 201. The auxiliary drive assembly 203 includes a threaded long rod 2031, with fixed angle plates 2032 fixedly connected to both ends of the threaded long rod 2031. A threaded sleeve block 2033 is threadedly fitted onto and connected to the outer side of the threaded long rod 2031. An arc-shaped brush 2034 is fixedly connected to both sides of the threaded sleeve block 2033. A second annular electric slide rail 2035 is rotatably fitted onto and connected to the outer side of the second annular electric slide rail 2035. A side connecting square plate 2036 is fixedly connected to the outer side of the second annular electric slide rail 2035. A slanted scraper 2037 is fixedly connected to one side of the second annular electric slide rail 2035. The side of the side connecting square plate 2036 away from the second annular electric slide rail 2035 is fixedly connected to the outer side of the first annular electric slide rail 202. The bottom of the fixed angle plate 2032 is fixedly connected to the top of the square base 1. Multiple threaded sleeve blocks 2033 are provided, and the multiple threaded sleeve blocks 2033 are symmetrically distributed on the threaded long rod 2031. On rod 2031, multiple arc-shaped brushes 2034 are provided, and the multiple arc-shaped brushes 2034 are distributed on both sides of threaded sleeve block 2033. In use, the main pipe is placed in the middle of the side pressure fixing mechanism 2 and aligned with the vertical electric slide rail 3. Then, the main pipe is clamped and fixed by the side pressure fixing mechanism 2. After the fixing is completed, the adjustable pipe clamping mechanism 4 is adjusted to the position aligned with the welding of the main pipe, and the branch pipes are inserted into the adjustable pipe clamping mechanism 4 in sequence. Then, the bottom slide plate 7 is moved by the hanging electric slide rail 6, which drives the two electric welding arms 8 at the bottom to move together. When the electric welding arms 8 move, the first half and the second half of the annular weld can be welded at the same time. After the welding is completed, the adjustable pipe clamping mechanism 4 is moved up to the top of the branch pipe by the vertical electric slide rail 3. At the same time, the fixing of the main pipe is released by the side pressure fixing mechanism 2, and the main pipe can be removed as a whole. The main pipe is placed between two circular concave shells 201. The auxiliary drive assembly 203 drives two annular electric slide rails 202 to move towards each other. As the annular electric slide rails 202 move, they move the inner circular concave shells 201, causing them to move towards one end of the main pipe, thus inserting one end of the main pipe into the concave shell. When one end of the main pipe contacts the arc-shaped grinding block 205 on the inner wall of the circular concave shell 201, the main pipe can be manually rotated to make its end face rub against the arc-shaped grinding block 205. By setting the arc-shaped grinding block 205 on the inner wall of the circular concave shell 201, the pre-fixed end face of the main pipe is ground smooth. The debris removed by the arc-shaped grinding block 205 will promptly exit through the arc-shaped passage on the inner wall of the circular concave shell 201. The debris is discharged outward through the hole 206. Multiple arc-shaped through holes 206 are provided on the inner wall of the circular concave shell 201 to facilitate the timely discharge of grinding debris. After the main pipe end face is ground, the circular concave shell 201 is driven to rotate by the annular electric slide rail 202. The rotation of the circular concave shell 201 drives the outer straightening arc block 207 to rotate until the straightening arc block 207 rotates to coincide and align with the outer straightening corner block 204 of the annular electric slide rail 202. At this point, the annular weld of the main pipe is in a directly upward position. The setting of the straightening arc block 207 and the straightening corner block 204 ensures that the annular weld of the main pipe is in a directly upward position. After straightening is completed, the auxiliary drive assembly 203 drives the circular concave shell 201 to move towards the main pipe again. As the main pipe moves, two circular concave shells 201 clamp the ends of the main pipe from both ends. When the ends of the main pipe need to be laterally pushed and fixed by the circular concave shells 201, the threaded sleeve 2033 is driven to rotate by the annular electric slide rail 2035 to engage with the threaded rod 2031. When the threaded sleeve 2033 engages with the threaded rod 2031, it drives the outer annular electric slide rail 2035 and the arc-shaped brushes 2034 on both sides to move together. As the threaded sleeve 2033 moves, the arc-shaped brushes 2034 clean the outer surface of the threaded rod 2031. When the annular electric slide rail 2035 moves, it drives the outer side connecting square plate 2036 and the oblique scraper 2037 on one side to move together. When the side connecting square plate 2036 moves, it drives the one-sided annular electric slide rail 202 to move, so that the circular concave shell 201 can be used to push and fix the end of the main pipe. By setting the side connecting square plates 2036 on both sides of the annular electric slide rail 202, the rotation limit of the second annular electric slide rail 2035 is achieved. When the inclined scraper 2037 moves together with the threaded sleeve block 2033, it scrapes and cleans the top surface of the square base 1. When the inclined scraper 2037 moves towards the vertical electric slide rail 3 with the threaded sleeve block 2033, it pushes a part of the welding slag along its inclined surface to the position of the fixed corner plate 2032. The inclined surface of the inclined scraper 2037 makes the pushed welding slag move towards the fixed corner plate 2032.
[0014] Please see Figures 1-8This invention provides a welding device for radiators of engineering machinery: an adjustable pipe clamping mechanism 4 includes an inner sliding plate 401, a rectangular through hole 402 on one side of the inner sliding plate 401, an annular sleeve block 403 slidably connected to the inner wall of the rectangular through hole 402, an outer angle plate 404 fixedly connected to the outer side of the annular sleeve block 403, a fixing rod 405 penetrating and fixedly connected to the top of the outer angle plate 404, a curved pressure plate 406 sleeved and slidably connected to the outer side of the fixing rod 405, and a return spring 407 fixedly connected to the inner side of the curved pressure plate 406. One side of the inner sliding plate 401... The side slides slidably connected to the inner side of the vertical electric slide rail 3. Multiple annular sleeve blocks 403 are provided, distributed along the inner wall of the rectangular through hole 402. Multiple external angle plates 404 are provided, symmetrically distributed on the outer side of the annular sleeve blocks 403. Multiple curved pressure plates 406 are provided, symmetrically distributed at both ends of the return spring 407. In use, after the main pipe is fixed, the branch pipe is inserted into the annular sleeve block 403. By moving the annular sleeve block 403, the branch pipe is moved to a position aligned with the annular weld of the main pipe. The sliding engagement between block 403 and rectangular through hole 402 allows for adjustment of the branch pipe position to accommodate different docking positions. Then, the two curved pressure plates 406 are pushed to move towards each other to compress the return spring 407. Simultaneously, the two curved pressure plates 406 are rotated into the rectangular through hole 402. At this point, the return spring 407 applies a pushing force to the top and bottom curved pressure plates 406 through its extension force, causing the curved pressure plates 406 to be fixed in the rectangular through hole 402. The extension force of the return spring 407 pushes the curved pressure plates 406 into tight contact with the inner wall of the rectangular through hole 402. The position of the branch pipe inside the annular sleeve 403 is fixed. After the main pipe and the branch pipe are welded, the inner sliding plate 401 is moved up to the top of the branch pipe by the vertical electric slide rail 3 to release the clamping restriction on the branch pipe. Press the two curved pressure plates 406 to move towards each other and compress the return spring 407. At the same time, rotate the curved pressure plates 406 around the fixed through rod 405 out of the rectangular through hole 402 to remove the annular sleeve 403 from the rectangular through hole 402. The telescopic push-press fixing of the two curved pressure plates 406 and the return spring 407 facilitates the disassembly and installation of the adjustable pipe clamping mechanism 4.
[0015] When using this invention, the main pipe is placed in the middle of the side pressure fixing mechanism 2 and aligned with the vertical electric slide rail 3. Then, the main pipe is clamped and fixed by the side pressure fixing mechanism 2. After fixing, the adjustable pipe clamping mechanism 4 is adjusted to the position aligned with the welding of the main pipe, and the branch pipes are inserted into the adjustable pipe clamping mechanism 4 in sequence. Then, the bottom slide plate 7 is moved by the hanging electric slide rail 6, which drives the two electric welding arms 8 at the bottom to move together. When the electric welding arms 8 move, the first half and the second half of the circumferential weld can be welded at the same time. After welding, the adjustable pipe clamping mechanism 4 is moved up to the top of the branch pipe by the vertical electric slide rail 3. At the same time, the fixing of the main pipe is released by the side pressure fixing mechanism 2, and the main pipe can be removed as a whole. The main pipe is placed between two circular concave shells 201. The auxiliary drive assembly 203 drives two annular electric slide rails 202 to move towards each other. As the annular electric slide rails 202 move, they move the inner circular concave shells 201, causing them to move towards one end of the main pipe, thus inserting one end of the main pipe into the concave shell. When one end of the main pipe contacts the arc-shaped grinding block 205 on the inner wall of the circular concave shell 201, the main pipe can be manually rotated to make its end face rub against the arc-shaped grinding block 205. By setting the arc-shaped grinding block 205 on the inner wall of the circular concave shell 201, the pre-fixed end face of the main pipe is ground smooth. The debris removed by the arc-shaped grinding block 205 is promptly discharged outwards through the arc-shaped through hole 206 on the inner wall of the circular concave shell 201. Multiple arc-shaped through holes 206 are opened on the inner wall of the circular concave shell 201 to facilitate the timely discharge of grinding debris. After the end face of the main pipe is ground, the circular concave shell 201 is driven to rotate by the annular electric slide rail 202. The rotation of the circular concave shell 201 drives the outer straightening arc block 207 to rotate until the straightening arc block 207 rotates to coincide and align with the straightening corner block 204 on the outer side of the annular electric slide rail 202. At this time, the annular weld of the main pipe is in a position directly facing upward. The setting of the straightening arc block 207 and the straightening corner block 204 ensures that the annular weld of the main pipe is in a position directly facing upward. After the straightening is completed, the auxiliary drive assembly 203 drives the circular concave shell 201 to move towards the main pipe again. The two circular concave shells 201 respectively move towards the end of the main pipe from both ends. When the internal clamping type fixation requires lateral pushing and fixing of the main pipe end via the circular concave shell 201, the threaded sleeve 2033 is driven to rotate by the annular electric slide rail 2035 to engage with the threaded long rod 2031. When the threaded sleeve 2033 engages with the threaded long rod 2031, it drives the outer annular electric slide rail 2035 and the two curved brushes 2034 to move together. As the threaded sleeve 2033 moves, the curved brushes 2034 clean the outer surface of the threaded long rod 2031. When the annular electric slide rail 2035 moves, it drives the outer side connecting square plate 2036 and the one-sided inclined scraper 2037 to move together. When the side connecting square plate 2036 moves, it drives the one-sided annular electric slide rail 202 to move, causing the circular concave shell 201 to engage with the main pipe end. The end of the main pipe is fixed by a side-push type. Side connecting square plates 2036 are simultaneously installed on both sides of the annular electric slide rail 202 to limit the rotation of the second annular electric slide rail 2035. When the inclined scraper 2037 moves together with the threaded sleeve 2033, it scrapes and cleans the top surface of the square base 1. As the inclined scraper 2037 moves towards the square vertical electric slide rail 3 with the threaded sleeve 2033, it pushes a portion of the welding slag along its inclined surface towards the fixed angle plate 2032. The inclined surface of the inclined scraper 2037 causes the pushed welding slag to move towards the fixed angle plate 2032. After the main pipe is fixed, the branch pipe is inserted into the annular sleeve 403. By moving the annular sleeve 403, the branch pipe is moved to a position aligned with the annular weld seam of the main pipe.The branch pipe position is adjusted to accommodate different docking positions by sliding the annular sleeve 403 with the rectangular through hole 402. Then, the two curved pressure plates 406 are pushed to move towards each other to compress the return spring 407. At the same time, the two curved pressure plates 406 are rotated into the rectangular through hole 402. At this time, the return spring 407 applies a pushing force to the top and bottom curved pressure plates 406 through its extension force, so that the curved pressure plates 406 are pushed and fixed in the rectangular through hole 402. The extension force of the return spring 407 pushes the curved pressure plates 406 tightly against the inner wall of the rectangular through hole 402. The contact mechanism secures the branch pipe within the annular sleeve 403. After the main pipe and branch pipe are welded together, the vertical electric slide rail 3 drives the inner sliding plate 401 to move upwards to the top of the branch pipe, thus releasing the clamping restriction on the branch pipe. Pressing the two curved pressure plates 406 moves them towards each other and compresses the return spring 407. Simultaneously, the curved pressure plates 406 rotate around the fixing rod 405 out of the rectangular through hole 402, allowing the annular sleeve 403 to be removed from the rectangular through hole 402. The telescopic pushing and fixing of the two curved pressure plates 406 and the return spring 407 facilitates the disassembly and installation of the adjustable pipe clamping mechanism 4.
