Description

Technical Field

[0001] This invention relates to the field of welding technology, and more specifically to a continuous vacuum chamber welding apparatus. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Modern welding utilizes a variety of energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. Besides its use in factories, welding can be performed in various environments, such as outdoors, underwater, and in space. During welding, the workpiece and solder melt to form a molten zone, and the weld pool cools and solidifies to form a bond between the materials. Pressure is usually applied during this process.

[0003] In existing technologies, aerospace vacuum chambers typically require welding during production. Due to the high welding requirements, a common welding method is to insert a stirring welding head into the workpiece at high speed. This causes frictional heat to plasticize and stir the material, forming a solid-state bond. As a result, this type of welding operation involves high temperatures, which poses a risk of overheating and damage to the stirring welding head during continuous production. This often necessitates stopping the machine to replace or cool the stirring welding head, thus affecting its performance. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a continuous vacuum chamber welding device to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A continuous vacuum chamber welding apparatus includes several welding mounting parts and a connector for mounting the welding mounting parts, wherein the welding mounting parts are used to mount welding heads. A cooling assembly includes a cooling cover and two cooling jackets and two circulating cooling pipes disposed inside the cooling cover. Each cooling jacket and each circulating cooling pipe form a group. The cooling jackets can be driven to move and cool down the high-temperature welded components. The replacement component includes an exchange component and a plurality of fixing components disposed on the outer wall of the exchange component. The fixing components can be driven to move and limit and fix the welded mounting component. The exchange component can be driven to move up and down in the direction of the central axis of the mounting component, and the exchange component can be driven to rotate around its central axis. When the exchange component rotates, it drives the plurality of fixing components and the welded mounting components limited inside it to rotate alternately, so that they can be rotated and cooled.

[0006] By adopting the above technical solution, multiple welding mounting parts and the welding heads installed at their bottoms can be replaced and used by replacing the components. The welding mounting parts with high-temperature welding heads will enter the interior and be cooled by the cooling component. During this process, the replacement component will exchange the welding mounting parts that do not generate high temperature to the interior of the assembly for use. In this way, when the assembly is performing welding operations, the high-temperature welding heads can be continuously replaced and cooled. At the same time, the cooled welding heads can be installed and used, thereby avoiding the shutdown due to overheating of the welding heads during the welding process, and achieving the effect of continuous welding.

[0007] Preferably, the cooling assembly further includes: a second positioning block, the second positioning block being fixedly installed on the inner bottom surface of the cooling cover, a second infrared temperature sensor being fixedly installed on both sides of the second positioning block, a plurality of positioning posts being fixedly installed on the inner bottom surface, a first reset member being movably sleeved on the outer circular wall of the positioning posts, the cooling cover being slidably connected to the positioning posts, and a third pneumatic adjustment member being fixedly installed on the bottom surface, the third pneumatic adjustment member having telescopic rods at both ends, a hinge being rotatably connected to one end of the telescopic rod of the third pneumatic adjustment member, and one end of the hinge being rotatably connected to the bottom surface of the cooling cover.

[0008] When the exchange component rotates and rotates the welding mounting component with the high-temperature welding head into the interior, the interior is inflated. Then, two telescopic rods extend from both ends of the third pneumatic adjustment component. Subsequently, the rebound force of the first reset component pushes the cooling sleeve upward. Then, the cooling sleeve wraps around the high-temperature welding head at the bottom of the welding mounting component. At this time, coolant is delivered through the circulating cooling pipe to cool the cooling sleeve and the high-temperature welding head.

[0009] Preferably, the replacement assembly further includes: a first pneumatic adjusting component, the first pneumatic adjusting component having a telescopic rod internally disposed therein, a connecting component fixedly mounted on the bottom surface of the telescopic rod, the outer circular wall surface of the telescopic rod of the first pneumatic adjusting component being fixedly mounted to the cooling cover, a second driving component being fixedly mounted internally therein, the bottom surface of the drive shaft of the second driving component being fixedly mounted to the connecting component, a second pneumatic adjusting component being fixedly mounted on the bottom surface of the connecting component, the second pneumatic adjusting component being rotatably connected to the drive shaft of the second driving component, and a plurality of first connecting posts being movably sleeved internally therein. A first elastic element is movably sleeved on the outer circular wall of the connecting column. Each first connecting column and one of the fixing elements form a group. One end of the first connecting column is fixedly installed with the fixing element. A positioning element is fixedly installed on the top surface of the fixing element. Second mounting cylinders are fixedly installed on both sides of the positioning element. A third elastic element is movably sleeved inside the second mounting cylinder. A third connecting column is slidably connected inside the second mounting cylinder. A chuck is rotatably connected to one end of the third connecting column. A telescopic rod is provided inside the second pneumatic adjusting element. A docking block is fixedly installed at one end of the telescopic rod inside the second pneumatic adjusting element.

[0010] By adopting the above technical solution, when the exchange component is in use, the first pneumatic adjustment component is inflated, causing its internal telescopic rod to extend and move the connecting component and the exchange component downwards simultaneously. This moves the exchange component to a position corresponding to the welded mounting component at the bottom of the assembly. Then, by inflating the second pneumatic adjustment component, its internal telescopic rod moves, causing the docking block to move into the positioning component. At this point, the two retaining rollers, under the rebound force of the third elastic component, engage on both sides of the docking block, allowing the docking block to mate with the fixing component. Furthermore, with the continuous extension of the telescopic rod of the second pneumatic adjustment component, the fixing component moves away from the exchange component and fits onto the welded mounting component at the bottom of the assembly. The external part of the component is then moved downwards by the continuous downward movement of the telescopic rod of the first pneumatic adjustment component, causing the fixing component to pull the welding mounting component inside the assembly component downwards, thereby separating the welding mounting component and the assembly component. After the above steps are completed, by drawing the air inside the first and second pneumatic adjustment components to a negative pressure state, the exchange component and the fixing component can be reset. Then, the exchange component can be driven to rotate by the second drive component to replace the cooled welding mounting component and the high-temperature welding mounting component. By moving the telescopic rod inside the first pneumatic adjustment component upwards, the cooled welding mounting component is connected and installed with the assembly component, thereby achieving the effect of exchanging the cooled welding mounting component and the high-temperature welding mounting component.

[0011] Preferably, two first mounting cylinders are fixedly installed on the outer circular wall of the fixing member, a second elastic member is movably sleeved inside the first mounting cylinder, a second connecting column is slidably connected inside the first mounting cylinder, and a second limiting wheel is rotatably connected to one end of the second connecting column.

[0012] By adopting the above technical solution, when the fastener is fitted onto the outside of the welded mounting component, the rebound force of the two second elastic elements will drive the second limiting wheel to squeeze the welded mounting component, thereby limiting the welded mounting component inside the fastener and preventing the welded mounting component from falling off during replacement.

[0013] Preferably, the mounting component has a rotatably connected internal support column, the bottom surface of the support column is hinged with a plurality of fixing claws, and the outer wall surface of the plurality of fixing claws is movably sleeved with a second reset component.

[0014] By adopting the above technical solution, when the welding mounting part enters the interior of the assembly, its top will squeeze multiple fixing claws and move away from each other at the same time. Then, when the top of the welding mounting part enters the bottom of the receiving column, the rebound force of the second reset part will drive the multiple fixing claws to reset, thereby limiting and fixing the top of the welding mounting part.

[0015] Preferably, two mounting covers are fixedly installed on the outer circular wall of the mounting component. Each mounting cover has a cavity inside. A mounting block is slidably connected inside the mounting cover. The mounting block is sealed to the cavity inside the mounting cover. A guide wheel is rotatably connected to one side of the mounting block. The cavity inside the mounting cover can be evacuated and inflated.

[0016] By adopting the above technical solution, when the welding mounting component is installed inside the assembly and ready for use, the chamber inside the mounting cover is inflated. Under the action of air pressure, the mounting block will drive the guide wheel to move, and then the guide wheel will fit against the outside of the welding mounting component. This can guide and limit the middle part of the welding mounting component when it is in use, thereby improving its stability during use.

[0017] Preferably, a fourth pneumatic drive component is fixedly installed on the outer circular wall of the assembly, the fourth pneumatic drive component has a telescopic rod inside, a receiving plate is fixedly installed on the bottom surface of the telescopic rod, two closed covers are rotatably connected to the bottom surface of the assembly, a plurality of first limiting wheels are rotatably connected inside the closed covers, a first positioning block is fixedly installed on the outer circular wall of the closed covers, a first infrared temperature sensor is fixedly installed inside the first positioning block, a first connecting rod is rotatably connected to the outer circular wall of the first positioning block, a second connecting rod is rotatably connected to one end of the first connecting rod, and one end of the second connecting rod is connected to the receiving plate in a universal ball joint manner.

[0018] By adopting the above technical solution, when the welding installation component inside the assembly is ready for use, air is supplied to the inside of the fourth pneumatic drive component, causing the internal telescopic rod to extend. Then, the telescopic rod and the receiving plate move downwards simultaneously, driving the two second connecting rods to rotate. In turn, the second connecting rods drive the first connecting rod to rotate. When the first connecting rod rotates to its limit and can no longer rotate, the two closed covers simultaneously approach and close. At this time, the multiple first limiting wheels inside the closed covers will engage with the outside of the bottom end of the welding installation component, thereby limiting and fixing the bottom end of the welding installation component and improving its stability during use. At the same time, when the welding installation component is in operation, the temperature of the welding head of the welding installation component can be monitored by the first infrared temperature sensor to prevent overheating.

[0019] Preferably, a mounting bracket is fixedly installed on the top surface of the mounting component, a coupling is provided inside the mounting bracket, the inner circular wall of the coupling is fixedly sleeved with the receiving column, a first driving component is fixedly installed on the top surface of the mounting bracket, the outer circular wall of the driving shaft of the first driving component is fixedly sleeved with the coupling, a sliding cover is fixedly installed on one side of the mounting bracket, a slide rail is fixedly installed on one side of the connecting component, the slide rail is slidably connected with the sliding cover, and one side of the mounting bracket is fixedly installed on the moving platform of the welding equipment.

[0020] By adopting the above technical solution, the first driving component can drive the assembly to rotate, thereby enabling the welding installation component and the welding head at its bottom to rotate and be used. Then, the moving table of the welding equipment can move the assembly, the welding installation component and the welding head at its bottom, so that the welding head meets the pressure required for stirring welding. At the same time, the moving table of the welding equipment can move the entire device away from the welding workpiece, avoiding interference from the welding workpiece with the alternating use of the welding installation component.

[0021] In summary, the present invention has the following main beneficial effects: 1. This invention achieves automatic alternation and cooling of welding heads by replacing components, allowing for the replacement of high-temperature welding heads during welding operations without stopping the machine. While the high-temperature welding head is being replaced and cooled, a cooled welding head is immediately installed to continue working, thereby achieving a continuous and uninterrupted welding process and effectively avoiding operation interruptions caused by overheating of the welding head.

[0022] 2. This invention provides multiple fixation, guidance and temperature monitoring through the assembly. When used for welding, the assembly can reliably limit and fix the top, middle and bottom of the welding installation, which significantly improves the stability and accuracy of the welding process. At the same time, the temperature of the welding head is monitored in real time by the first infrared temperature sensor, which can trigger the replacement process before it overheats, thus playing a preventive protection role.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0026] Example: Reference Figure 1 , Figure 2 and Figure 3 A continuous vacuum chamber welding device includes: a plurality of welding mounting parts 500, and a mounting part 100 for mounting and using the welding mounting parts 500, wherein the welding mounting parts 500 are used to mount welding heads. refer to Figure 3 , Figure 9 The cooling assembly includes a cooling cover 300 and two cooling sleeves 310 and two circulating cooling pipes 313 disposed inside the cooling cover 300. Each cooling sleeve 310 and one circulating cooling pipe 313 form a group. The cooling sleeves 310 can be driven to move and cool down the high-temperature welded mounting parts 500. refer to Figure 5 , Figure 6The replacement component includes an exchange component 200 and a plurality of fixing members 240 disposed on the outer wall of the exchange component 200. The fixing members 240 can be driven to move and limit and fix the welding mounting member 500. The exchange component 200 can be driven to move up and down in the direction of the central axis of the mounting member 100, and the exchange component 200 can be driven to rotate along its central axis. When the exchange component 200 rotates, it drives the plurality of fixing members 240 and the welding mounting member 500 limited inside it to rotate alternately, so that it can be rotated and cooled.

[0027] The replacement component allows for the replacement of multiple welding mounting parts 500 and the welding heads mounted on their bottoms. The welding mounting parts 500 with high-temperature welding heads are then cooled inside the cooling shroud 300 by the cooling component. During this process, the replacement component exchanges welding mounting parts 500 that do not generate high temperatures for use inside the assembly 100. This allows the high-temperature welding heads to be continuously replaced and cooled while the assembly 100 is performing welding operations. The cooled welding heads can then be installed and used, thus avoiding shutdowns due to overheating of the welding heads during the welding process and achieving continuous welding.

[0028] Based on the above embodiments, refer to Figure 2 , Figure 3 and Figure 9 The cooling assembly also includes: a second positioning block 320, which is fixedly installed on the inner bottom surface of the cooling cover 300. A second infrared temperature sensor 321 is fixedly installed on both sides of the second positioning block 320. A plurality of positioning posts 311 are fixedly installed on the inner bottom surface of the cooling cover 300. A first reset member 312 is movably sleeved on the outer circular wall of the positioning post 311. The cooling cover 310 is slidably connected to the positioning post 311. A third pneumatic adjustment member 330 is fixedly installed on the bottom surface of the cooling cover 300. Both ends of the third pneumatic adjustment member 330 are provided with telescopic rods. One end of the telescopic rod of the third pneumatic adjustment member 330 is rotatably connected to a hinge member 331. One end of the hinge member 331 is rotatably connected to the bottom surface of the cooling cover 310.

[0029] When the exchange component 200 rotates to rotate the welding mounting component 500 with the high-temperature welding head into the interior of the cooling cover 300, the interior of the cooling cover 300 is inflated, and then two telescopic rods extend from both ends of the third pneumatic adjustment component 330. Then, the rebound force of the first reset component 312 pushes the cooling sleeve 310 upward, and then the cooling sleeve 310 wraps the high-temperature welding head at the bottom of the welding mounting component 500. At this time, coolant is delivered through the circulating cooling pipe 313 to cool the cooling sleeve 310 and the high-temperature welding head.

[0030] Based on the above embodiments, refer to Figure 3 , Figure 4 , Figure 6 , Figure 6 , Figure 7 and Figure 8 The replacement component also includes: a first pneumatic adjustment component 210, which has a telescopic rod inside. A connector 220 is fixedly installed on the bottom surface of the telescopic rod. The outer circular wall of the telescopic rod of the first pneumatic adjustment component 210 is fixedly installed with the cooling cover 300. A second drive component 221 is fixedly installed inside the connector 220. The bottom surface of the drive shaft of the second drive component 221 is fixedly installed with the connector 220. A second pneumatic adjustment component 230 is fixedly installed on the bottom surface of the connector 220. The second pneumatic adjustment component 230 is rotatably connected to the drive shaft of the second drive component 221. Several first connecting posts 250 are movably sleeved inside the exchange component 200. The outer circular wall of the first connecting post 250... The first elastic element 251 is movably sleeved on the surface. Each first connecting post 250 and a fixing member 240 form a group. One end of the first connecting post 250 is fixedly installed with the fixing member 240. A positioning member 245 is fixedly installed on the top surface of the fixing member 240. A second mounting cylinder 246 is fixedly installed on both sides of the positioning member 245. A third elastic element 247 is movably sleeved inside the second mounting cylinder 246. A third connecting post 248 is slidably connected inside the second mounting cylinder 246. A chuck 249 is rotatably connected to one end of the third connecting post 248. A telescopic rod is provided inside the second pneumatic adjusting member 230. A docking block 231 is fixedly installed on one end of the telescopic rod inside the second pneumatic adjusting member 230.

[0031] When the exchange component 200 is in use, the first pneumatic adjustment component 210 is inflated, causing its internal telescopic rod to extend and move the connector 220, exchange component 200, and cooling cover 300 downwards simultaneously. This moves the exchange component 200 to a position corresponding to the welded mounting component 500 at the bottom of the assembly 100. Then, the second pneumatic adjustment component 230 is inflated, causing its internal telescopic rod to move and move the docking block 231 into the positioning component 245. At this point, the two retaining rollers 249 engage with the sides of the docking block 231 under the rebound force of the third elastic element 247, allowing the docking block 231 to dock with the fixing component 240. Furthermore, the continuous extension of the telescopic rod of the second pneumatic adjustment component 230 moves the fixing component 240 away from the exchange component 200, fitting the fixing component 240 onto the welded mounting component 500 at the bottom of the assembly 100. The external part of the mounting component 500, and then under the continuous downward movement of the telescopic rod of the first pneumatic adjustment component 210, the fixing component 240 pulls the welding mounting component 500 inside the mounting component 100 downward, thereby separating the welding mounting component 500 and the mounting component 100. After the above steps are completed, by drawing the air inside the first pneumatic adjustment component 210 and the second pneumatic adjustment component 230 to a negative pressure state, the exchange component 200 and the fixing component 240 can be reset. Then, the exchange component 200 can be driven to rotate by the second driving component 221 to replace the cooled welding mounting component 500 and the high-temperature welding mounting component 500. And by moving the telescopic rod inside the first pneumatic adjustment component 210 upward, the cooled welding mounting component 500 is connected and installed with the mounting component 100 for use, thereby achieving the effect of exchanging the cooled welding mounting component 500 and the high-temperature welding mounting component 500 for use.

[0032] Based on the above embodiments, refer to Figure 5 and Figure 6 Two first mounting cylinders 241 are fixedly installed on the outer circular wall of the fastener 240. A second elastic element 242 is movably sleeved inside the first mounting cylinder 241. A second connecting post 243 is slidably connected inside the first mounting cylinder 241. A second limiting wheel 244 is rotatably connected to one end of the second connecting post 243.

[0033] When the fastener 240 is fitted onto the outside of the welded mounting part 500, the rebound force of the two second elastic elements 242 will drive the second limiting wheel 244 to squeeze the welded mounting part 500, so that the welded mounting part 500 is limited inside the fastener 240, thereby preventing the welded mounting part 500 from falling off when it is replaced.

[0034] Based on the above embodiments, refer to Figure 10 and Figure 11The internal rotatable connection of the mounting component 100 is a receiving column 110, the bottom surface of the receiving column 110 is hinged with several fixing claws 111, and the outer wall surface of the several fixing claws 111 is movably sleeved with a second reset component 112.

[0035] When the welding mounting component 500 enters the interior of the mounting component 100, its top will press multiple fixing claws 111 away from each other. Then, when the top of the welding mounting component 500 enters the bottom of the receiving column 110, the rebound force of the second reset component 112 will drive the multiple fixing claws 111 to reset, thereby limiting and fixing the top of the welding mounting component 500.

[0036] Based on the above embodiments, refer to Figure 10 , Figure 11 and Figure 12 Two mounting covers 120 are fixedly installed on the outer circular wall of the mounting component 100. The mounting cover 120 has a cavity inside. A mounting block 121 is slidably connected inside the mounting cover 120. The mounting block 121 is sealed to the cavity inside the mounting cover 120. A guide wheel 122 is rotatably connected to one side of the mounting block 121. The cavity inside the mounting cover 120 can be evacuated and inflated.

[0037] When the welding mounting component 500 is installed inside the mounting component 100 and is ready for use, the cavity inside the mounting cover 120 is inflated. Under the action of air pressure, the mounting block 121 will drive the guide wheel 122 to move. Then the guide wheel 122 will fit against the outside of the welding mounting component 500. This can guide and limit the middle part of the welding mounting component 500 when it is in use, thereby improving its stability during use.

[0038] Based on the above embodiments, refer to Figure 10 and Figure 13 A fourth pneumatic drive component 130 is fixedly installed on the outer circular wall of the mounting component 100. The fourth pneumatic drive component 130 has a telescopic rod inside. A receiving plate 131 is fixedly installed on the bottom surface of the telescopic rod. Two closed covers 140 are rotatably connected to the bottom surface of the mounting component 100. Several first limit wheels 145 are rotatably connected inside the closed covers 140. A first positioning block 141 is fixedly installed on the outer circular wall of the closed covers 140. A first infrared temperature sensor 142 is fixedly installed inside the first positioning block 141. A first connecting rod 143 is rotatably connected to the outer circular wall of the first positioning block 141. A second connecting rod 144 is rotatably connected to one end of the first connecting rod 143. One end of the second connecting rod 144 is connected to the receiving plate 131 in a universal ball joint manner.

[0039] When the welding mounting component 500 inside the assembly 100 is ready for use, air is supplied to the fourth pneumatic drive component 130, causing its internal telescopic rod to extend. Then, the telescopic rod and the receiving plate 131 move downwards simultaneously, causing the two second connecting rods 144 to rotate. In turn, the second connecting rods 144 drive the first connecting rod 143 to rotate. When the first connecting rod 143 rotates to its limit and can no longer rotate, the two closing covers 140 simultaneously approach and close. At this time, the multiple first limiting wheels 145 inside the closing cover 140 will engage with the outside of the bottom end of the welding mounting component 500, thereby limiting and fixing the bottom end of the welding mounting component 500 and improving its stability during use. At the same time, when the welding mounting component 500 is in operation, the temperature of the welding head of the welding mounting component 500 can be monitored by the first infrared temperature sensor 142 to prevent overheating.

[0040] Based on the above embodiments, refer to Figure 1 and Figure 2 A mounting bracket 400 is fixedly installed on the top surface of the mounting component 100. A coupling 700 is provided inside the mounting bracket 400. The inner circular wall of the coupling 700 is fixedly sleeved with the receiving column 110. A first driving component 600 is fixedly installed on the top surface of the mounting bracket 400. The outer circular wall of the drive shaft of the first driving component 600 is fixedly sleeved with the coupling 700. A sliding cover 212 is fixedly installed on one side of the mounting bracket 400. A slide rail 211 is fixedly installed on one side of the connecting component 220. The slide rail 211 is slidably connected to the sliding cover 212. One side of the mounting bracket 400 is fixedly installed on the moving platform of the welding equipment.

[0041] The first driving component 600 can drive the assembly 100 to rotate, thereby causing the welding mounting component 500 and the welding head at its bottom to rotate and be used. Then, the moving table of the welding equipment can move the assembly 100, the welding mounting component 500 and the welding head at its bottom, so that the welding head meets the pressure required for stir welding. At the same time, the moving table of the welding equipment can move the entire device away from the workpiece to avoid the workpiece interfering with the alternating use of the welding mounting component 500.

[0042] Working principle: Please refer to Figures 1-13 As shown, in use, the first driving component 600 can drive the mounting component 100 to rotate, thereby causing the welding mounting component 500 and the welding head at its bottom to rotate for use. Then, the moving table of the welding equipment can move the mounting component 100, the welding mounting component 500 and the welding head at its bottom, so that the welding head meets the pressure required for stir welding. At the same time, the moving table of the welding equipment can move the entire device away from the welding workpiece to avoid the welding workpiece interfering with the alternating use of the welding mounting component 500. When the welding mounting part 500 enters the interior of the mounting part 100, its top will press multiple fixing claws 111 away from each other at the same time. Then, when the top of the welding mounting part 500 enters the bottom of the receiving column 110, the rebound force of the second reset part 112 will drive the multiple fixing claws 111 to reset, thereby limiting and fixing the top of the welding mounting part 500. When the welding mounting component 500 is installed inside the mounting component 100 and is ready for use, the chamber inside the mounting cover 120 is inflated. Under the action of air pressure, the mounting block 121 will drive the guide wheel 122 to move. Then the guide wheel 122 will fit against the outside of the welding mounting component 500. This can guide and limit the middle part of the welding mounting component 500 when it is in use, thereby improving its stability during use. When the welding mounting component 500 inside the assembly component 100 is ready for use, air is supplied to the inside of the fourth pneumatic drive component 130, causing the telescopic rod inside to extend. Then, the telescopic rod and the receiving plate 131 move downwards simultaneously, causing the two second connecting rods 144 to rotate. In turn, the second connecting rods 144 drive the first connecting rod 143 to rotate. When the first connecting rod 143 rotates to its limit and can no longer rotate, the two closing covers 140 simultaneously approach and close each other. At this time, the multiple first limiting wheels 145 inside the closing cover 140 will engage with the outside of the bottom end of the welding mounting component 500, thereby limiting and fixing the bottom end of the welding mounting component 500 and improving its stability during use. At the same time, when the welding mounting component 500 is in operation, the temperature of the welding head of the welding mounting component 500 can be monitored by the first infrared temperature sensor 142 to prevent overheating. When the exchange component 200 is in use, the first pneumatic adjustment component 210 is inflated, causing its internal telescopic rod to extend and move the connector 220, exchange component 200, and cooling cover 300 downwards simultaneously. This moves the exchange component 200 to a position corresponding to the welded mounting component 500 at the bottom of the assembly 100. Then, inflation of the second pneumatic adjustment component 230 causes its internal telescopic rod to move, moving the docking block 231 into the positioning component 245. At this point, the two retaining rollers 249 engage with both sides of the docking block 231 under the rebound force of the third elastic element 247, allowing the docking block 231 to dock with the fixing component 240. Furthermore, the continuous extension of the telescopic rod of the second pneumatic adjustment component 230 moves the fixing component 240 away from the exchange component 200, fitting the fixing component 240 onto the welded mounting component at the bottom of the assembly 100. Outside of 500, and then under the continuous downward movement of the telescopic rod of the first pneumatic adjuster 210, the fixing member 240 pulls the welding mounting member 500 inside the mounting member 100 downward, thereby separating the welding mounting member 500 and the mounting member 100. After the above steps are completed, by drawing the air inside the first pneumatic adjuster 210 and the second pneumatic adjuster 230 to a negative pressure state, the exchange member 200 and the fixing member 240 can be reset. Then, the exchange member 200 can be driven to rotate by the second drive member 221 to replace the cooled welding mounting member 500 and the high-temperature welding mounting member 500. And by moving the telescopic rod inside the first pneumatic adjuster 210 upward, the cooled welding mounting member 500 is connected and installed with the mounting member 100 for use, thereby achieving the effect of exchanging the cooled welding mounting member 500 and the high-temperature welding mounting member 500 for use. When the exchange component 200 rotates to rotate the welding mounting component 500 with the high-temperature welding head into the interior of the cooling cover 300, the interior of the cooling cover 300 is inflated, and then two telescopic rods extend from both ends of the third pneumatic adjustment component 330. Then, the rebound force of the first reset component 312 pushes the cooling sleeve 310 upward, and then the cooling sleeve 310 wraps the high-temperature welding head at the bottom of the welding mounting component 500. At this time, coolant is delivered through the circulating cooling pipe 313 to cool the cooling sleeve 310 and the high-temperature welding head.
