[0044] Referring to Figure 1 and Figures 3 to 5As shown, specifically, the workpiece 5 to be welded in this embodiment is a pipe fitting, which includes a fixed end 51 and a movable end 52 sleeved on the fixed end 51, and the movable end 52 is communicated with the fixed end 51, and the connection between the movable end 52 and the fixed end 51 is the welding position. In the welding process, the lower end of the fixed end 51 is installed in the mounting member 42, and the fixed end 51 is communicated with the mounting member 42, and the welding position and the movable end 52 are located outside the mounting member 42. The welding process of the pipe fitting welding device in this embodiment is as follows: (1) according to the size and shape of the workpiece 5 to be welded, replace the corresponding mounting member 42, install the mounting member 42 on the carrier 41, and then install the workpiece 5 to be welded on the mounting member 42; (2) drive the wire feeding mechanism 2 and the welding mechanism 3 to the work station where the workpiece 5 to be welded is located by moving the driving mechanism 1; (3) the air chamber 411 introduces protective gas into the workpiece 5 to be welded through the mounting member 42 to avoid harmful reactions such as oxidation and nitriding that may occur at the welding position during welding, the wire feeding mechanism 2 starts to work and delivers the welding wire to the welding position on the workpiece 5 to be welded, and the welding mechanism 3 melts the welding wire, and the melted welding wire flows to the welding position to complete the welding operation.

[0045] The pipe fitting welding device in this embodiment can adapt to welding of pipe fittings of different sizes and shapes by replacing different mounting members 42, has very high flexibility and versatility, and by installing the fixed end 51 in the mounting member 42 and ensuring that the fixed end 51 is connected with the mounting member 42, the movable end 52 is located outside the mounting member 42, such a layout not only facilitates the operation and management of the welding process, but also ensures accurate positioning of the welding position, thereby improving the welding quality and consistency of the weld. In addition, the welding operation process is clear and efficient, from replacing the mounting member 42, installing the workpiece 5 to be welded, to moving the driving mechanism 1 to drive the wire feeding mechanism 2 and the welding mechanism 3 to the work station, and then introducing protective gas, feeding and melting the welding wire, each link is closely connected, which greatly improves the welding efficiency. At the same time, by effectively introducing protective gas through the air chamber 411 in the carrier 41 and the mounting member 42, harmful reactions such as oxidation and nitriding during welding are avoided, which not only ensures the welding quality, but also prolongs the service life of the pipe fitting. Overall, the device is designed reasonably, the mechanisms are connected closely and easy to operate, and the design of the machine frame 6 also facilitates daily maintenance, ensuring the convenience and reliability of the equipment.

[0046] More specifically, the pipe fitting welding device in the embodiment further comprises a rectangularly designed machine frame 6, the moving driving mechanism 1, the wire feeding mechanism 2, the welding mechanism 3 and the workpiece fixing mechanism 4 are all installed on the machine frame 6, wherein the moving driving mechanism 1, the wire feeding mechanism 2 and the welding mechanism 3 are located on one side of the machine frame 6, and the workpiece fixing mechanism 4 is installed on the other side, the structure is compact, and the mutual interference between the mechanisms is effectively avoided, so that the wire feeding, moving and welding actions in the welding process can be smoothly performed, thereby further improving the welding efficiency. In addition, the machine frame 6 is provided with a storage cabinet 61, various circuits and gas path elements connected by the moving driving mechanism 1, the wire feeding mechanism 2, the welding mechanism 3 and the workpiece fixing mechanism 4 are arranged in the storage cabinet 61, which avoids the circuits and gas path elements being randomly hung or scattered outside the machine frame 6, thereby greatly improving the neatness and aesthetics of the machine, and the circuits and gas path elements can be effectively prevented from being damaged due to external force collision, friction or misoperation, thereby reducing the failure rate and maintenance cost. At the same time, the storage cabinet 61 can also provide a certain degree of protection effect to prevent dust, moisture and other pollutants from entering the circuit and gas path system, thereby ensuring the stable operation and safety of the system.

[0047] Referring to Figure 1 and Figure 3 As shown in the drawings, in a specific embodiment, the carrier 41 is provided with an air inlet 412 and an air outlet 413 communicated with the air chamber 411, and the mounting member 42 is in interference fit with the air outlet 413 near one end of the carrier 41.

[0048] Specifically, the carrier 41 is horizontally arranged, a plurality of gas outlets 413 are uniformly arranged along the length direction (i.e. the X-axis direction) of the carrier 41, and the gas outlets 413 are arranged on the upper surface of the carrier 41, and the gas inlets 412 are arranged away from the movement driving mechanism 1, the wire feeding mechanism 2, the welding mechanism 3 and the mounting member 42, the number of the mounting members 42 is consistent with the number of the gas outlets 413, and a plurality of to-be-welded workpieces 5 are correspondingly mounted on the carrier 41. The protective gas flows into the gas chamber 411 through the gas inlets 412, then flows to the mounting member 42 through the gas outlets 413, and finally flows into the to-be-welded workpiece 5. By uniformly arranging the gas outlets 413 on the upper surface of the carrier 41 along the X-axis direction, it is ensured that the protective gas flowing out of the gas chamber 411 can uniformly cover each to-be-welded workpiece 5, and the operation of the mounting member 42 on the wire feeding mechanism 2 and the welding mechanism 3 is avoided to interfere, so that the wire feeding mechanism 2 and the welding mechanism 3 can be more flexible to move and adjust, and the movement path of the wire feeding mechanism 2 and the welding mechanism 3 is also simplified. In addition, the gas inlets 412 are arranged away from the movement driving mechanism 1, the wire feeding mechanism 2, the welding mechanism 3 and the mounting member 42 in order to prevent the gas pipe connected to the gas inlets 412 from interfering with the normal work of the driving mechanism, the wire feeding mechanism 2, the welding mechanism 3 and the mounting member 42. In addition, the mounting member 42 is in interference fit with the gas outlet 413 near one end of the carrier 41, which can ensure that a good seal is formed between the mounting member 42 and the gas outlet 413, prevent the protective gas from leaking, and also provide sufficient stability and support to ensure the stability of the to-be-welded workpiece 5 during the welding process.

[0049] In addition, the pipe welding device in the embodiment adopts a grouping welding mode when welding, the number of to-be-welded workpieces 5 in each group is determined according to the number of gas outlets 413 on the carrier 41, and in the welding process, the movement driving mechanism 1 drives the wire feeding mechanism 2 and the welding mechanism 3 to move to each work station where the to-be-welded workpiece 5 is located in sequence, so as to sequentially weld each to-be-welded workpiece 5. After the to-be-welded workpieces 5 in the group are all welded, the group of welded products is taken down and another group of to-be-welded workpieces 5 is put on. By adopting the grouping welding scheme, the to-be-welded workpieces 5 can be grouped according to their specifications, so that each to-be-welded workpiece 5 in the same group can receive the same welding parameters and conditions during the welding process, thereby improving the consistency and stability of the welding quality, and facilitating the movement path planning of the wire feeding mechanism 2 and the welding mechanism 3, reducing unnecessary movement distance, and thus reducing energy consumption.

[0050] Referring to Figure 1 and Figure 2As shown, in an embodiment, the mobile driving mechanism 1 comprises an X-axis driving module 11 and a Y-axis driving module 12; the X-axis driving module 11 is drivingly connected to the Y-axis driving module 12, for driving the Y-axis driving module 12 to move in the X-axis direction; the Y-axis driving module 12 is drivingly connected to the wire feeding mechanism 2 and the welding mechanism 3, for driving the wire feeding mechanism 2 and the welding mechanism 3 to move in the Y-axis direction.

[0051] Specifically, the X-axis driving module 11 is used to drive the Y-axis driving module 12 to move in the X-axis direction, and the Y-axis driving module 12 is used to drive the wire feeding mechanism 2 and the welding mechanism 3 to move in the Y-axis direction, so that the wire feeding mechanism 2 and the welding mechanism 3 can quickly and accurately move to the corresponding workstations, the operation is simple, the welding efficiency is improved, and welding defects caused by position deviation are avoided, which helps to improve the strength and sealing performance of the weld, thereby improving the welding quality.

[0052] In an embodiment, the Y-axis driving module 12 comprises a Y-axis mounting seat 121 and a first Y-axis driving module 122, and the wire feeding mechanism 2 comprises a wire feeding module 21 and a clamping module 22; the X-axis driving module 11 is drivingly connected to the Y-axis mounting seat 121, for driving the Y-axis mounting seat 121 to move in the X-axis direction; the first Y-axis driving module 122 and the wire feeding module 21 are mounted on the Y-axis mounting seat 121, and the first Y-axis driving module 122 is located on the side of the Y-axis mounting seat 121 close to the workpiece fixing mechanism 4; the first Y-axis driving module 122 is drivingly connected to the clamping module 22, for driving the clamping module 22 to move in the Y-axis direction.

[0053] Specifically, the wire feeding module 213 is used to feed the welding wire to the clamping module 22, which is used to clamp the welding wire so that the welding wire corresponds to the position to be welded. By integrating the wire feeding module 21 and the clamping module 22 on the Y-axis mounting seat 121, the integration of the system is further improved, the floor space is reduced, and the entire welding device is more compact and efficient. In addition, since the main task of the wire feeding module 213 is to stably feed the welding wire to the clamping module 22, if the wire feeding module 213 also moves on the Y-axis, it needs additional driving mechanism and control system to ensure the stability and accuracy of its movement, which not only increases the complexity of the system, but also may introduce additional errors. Therefore, fixing the wire feeding module 213 in a stable position can ensure the stability and accuracy of its wire feeding. The clamping module 22 needs to move with the change of the welding path to ensure that the welding is always aligned with the position to be welded. Therefore, the first Y-axis driving module 122 and the clamping module 22 are arranged on the Y-axis mounting seat 121 closer to the side of the workpiece fixing mechanism 4, and the first Y-axis driving module 122 is drivingly connected to the clamping module 22, which can make the clamping module 22 adapt to different welding paths and workpiece shapes flexibly, improve the flexibility and adaptability of welding, and also can reduce unnecessary movement and energy consumption, which helps to optimize the welding path.

[0054] Referring to Figure 2 As shown in the drawings, in a specific embodiment, the X-axis driving module 11 includes a driving member 111, a transmission screw rod 112 and a guide rail 113 arranged along the X-axis direction, the driving member 111 is drivingly connected to the transmission screw rod 112, the guide rail 113 is arranged parallel to the transmission screw rod 112, the transmission screw rod 112 is further drivingly connected to the Y-axis mounting seat 121, and the Y-axis mounting seat 121 is slidingly connected to the guide rail 113 to drive the Y-axis driving module 12 to move along the X-axis direction. The structure of the first Y-axis driving module 122 is consistent with that of the X-axis driving module 11, except that the first Y-axis driving module 122 is arranged along the Y-axis direction to drive the clamping module 22 to move in the Y-axis direction.

[0055] Specifically, by adopting the driving structure composed of the driving member 111, the transmission screw rod 112 and the guide rail 113, the driving structure of the X-axis driving module 11 and the first Y-axis driving module 122 is simple and stable, and precise motion control can be achieved, and the movement path is optimized, thereby improving the welding efficiency.

[0056] Referring to Figure 7As shown, in a specific embodiment, the wire feeding module 21 includes a wire feeding frame 211, a wire feeding tray 212, and a wire feeding module 213. The wire feeding frame 211 is mounted on the Y-axis mounting seat 121. The wire feeding tray 212 and the wire feeding module 213 are both mounted on the wire feeding frame 211. The wire feeding module 213 is located on the side of the wire feeding frame 211 close to the clamping module 22. The wire feeding module 213 is used to deliver the welding wire on the wire feeding tray 212 to the clamping module 22.

[0057] Specifically, the wire feeding module 213 includes a wire feeding drive 2131, a wire feeding drive gear 2132, a wire feeding driven gear 2133, a first wire feeding roller 2134, and a second wire feeding roller 2135. The wire feeding drive 2131 is drivingly connected to the wire feeding drive gear 2132. The wire feeding drive gear 2132 is meshingly connected to the wire feeding driven gear 2133. The wire feeding driven gear 2133 is coaxially connected to the first wire feeding roller 2134. The second wire feeding roller 2135 is arranged above the first wire feeding roller 2134.

[0058] More specifically, the wire feeding process of the pipe member welding device in the present embodiment is as follows: (1) When the wire feeding is needed, the wire feeding drive 2131 starts to work to provide power and drivingly connect to the wire feeding drive gear 2132. (2) The wire feeding drive gear 2132 meshes with the wire feeding driven gear 2133 to transmit power to the wire feeding driven gear 2133. (3) The wire feeding driven gear 2133 is coaxially connected to the first wire feeding roller 2134, so the first wire feeding roller 2134 starts to rotate. (4) The second wire feeding roller 2135 is arranged above the first wire feeding roller 2134 and keeps contact with the first wire feeding roller 2134 through a certain pressing force. When the first wire feeding roller 2134 rotates, the welding wire is clamped between the first wire feeding roller 2134 and the second wire feeding roller 2135 and moves forward with the rotation of the first wire feeding roller 2134, so that the welding wire is gradually pulled out from the wire feeding tray 212 and delivered to the clamping module 22 through the wire feeding module 213. (5) After the welding wire reaches the clamping module 22, it is clamped by the clamping module 22 and is ready for subsequent welding work.

[0059] The embodiment integrates the wire feeding module 21, the wire feeding tray 212, and the wire feeding frame 211 together, so that the wire feeding module 21 forms a compact and efficient wire feeding system. The compact structure helps to reduce the floor space occupied by the equipment and improve the space utilization. During the wire feeding process, the wire feeding drive 2131 provides stable power and ensures the smoothness of the wire feeding process through the gear transmission structure. At the same time, the stability of the welding wire during the conveying process is ensured through the pressing force between the first wire feeding roller 2134 and the second wire feeding roller 2135, avoiding the slipping or breaking of the welding wire. Moreover, the wire feeding process is completely controlled by the wire feeding drive 2131, realizing automatic wire feeding, improving work efficiency, reducing manual intervention, and reducing operation difficulty and labor intensity. In addition, the design of the wire feeding module 21 makes it can adapt to welding wires of different diameters and materials. By adjusting the speed and pressing force of the wire feeding drive 2131, the speed of the wire feeding can be accurately controlled to meet different welding requirements, improving the versatility and flexibility of the equipment.

[0060] Referring to Figure 8 In a specific embodiment, the clamping module 22 includes a wire feeding support 221, a wire feeding adjustment module 222, and a clamping support 223. The wire feeding adjustment module 222 is installed on the wire feeding support 221. The clamping support 223 is connected to the wire feeding adjustment module 222. The first Y-axis drive module 122 is transmissionally connected to the wire feeding support 221, and is used to drive the wire feeding support 221, the wire feeding adjustment module 222, and the clamping support 223 to move in the Y-axis direction.

[0061] Specifically, the wire feeding support 221 is driven by the first Y-axis drive module 122 to move in the Y-axis direction. The wire feeding adjustment module 222 is used to adjust the position of the clamping support 223, so as to adjust the position and tension of the welding wire clamped by the clamping support 223. After being finely adjusted by the wire feeding adjustment module 222, the clamping support 223 can accurately align the welding wire to the welding position. Through such integrated design, the wire feeding support 221, the wire feeding adjustment module 222, and the clamping support 223 have clear division of labor, thereby improving the reliability and stability of the system. Through the driving of the X-axis drive module 11 and the first Y-axis drive module 122 and the adjustment of the wire feeding adjustment module 222, the precise tracking of the welding path is facilitated, the welding wire can be more accurately aligned to the welding position, the welding accuracy and consistency are improved, and the welding quality and efficiency are improved.

[0062] In a specific embodiment, the wire feeding adjustment module 222 comprises a vertical adjustment assembly 2221, a horizontal adjustment assembly 2222 and an angle adjustment assembly 2223, the vertical adjustment assembly 2221 is installed on the wire feeding support 221, the vertical adjustment assembly 2221, the horizontal adjustment assembly 2222 and the angle adjustment assembly 2223 are connected in sequence, the clamping support 223 is connected to the horizontal adjustment assembly 2222, and the vertical adjustment assembly 2221, the horizontal adjustment assembly 2222 and the angle adjustment assembly 2223 are respectively used for adjusting the vertical position, the horizontal position and the angle of the clamping support 223.

[0063] Specifically, the vertical adjustment assembly 2221 comprises a vertical optical axis 22211 installed on the wire feeding support 221 and a vertical adjustment support 22212 slidingly connected to the vertical optical axis 22211; the horizontal adjustment assembly 2222 comprises a horizontal optical axis 22221 installed on the vertical adjustment support 22212 and a horizontal adjustment support 22222 slidingly connected to the horizontal optical axis 22221, and the length direction of the horizontal optical axis 22221 is arranged along the X axis; and the angle adjustment assembly 2223 comprises a rotating shaft 22231 installed on the horizontal adjustment support 22222 and an angle adjustment support 22232 rotatingly connected to the rotating shaft 22231. Through loose adjustment of the bolts on the vertical adjustment support 22212 and the horizontal adjustment support 22222, the vertical adjustment support 22212 and the horizontal adjustment support 22222 can be moved or fixed on the optical axis to adjust the vertical position and the horizontal position of the clamping support 223, and through loose adjustment of the bolts on the angle adjustment support 22232, the angle adjustment support 22232 can be rotated or fixed on the rotating shaft 22231 to adjust the angle of the clamping support 223.

[0064] The wire feeding adjustment module 222 in this embodiment realizes all-around adjustment of the clamping support 223 in three-dimensional space through the combination of the vertical adjustment assembly 2221, the horizontal adjustment assembly 2222 and the angle adjustment assembly 2223. This adjustment mode not only improves the flexibility of welding, but also ensures that the welding wire can accurately reach the welding position, thereby improving the precision and quality of welding. At the same time, through the design of the vertical optical axis 22211 and the horizontal optical axis 22221, and the sliding connection mode, the vertical adjustment support 22212 and the horizontal adjustment support 22222 can move smoothly on the optical axis, and the position of the support can be accurately controlled through the tightness of the adjusting bolt, thereby realizing high-precision adjustment. In addition, the tightening action of the bolt also ensures the stability of the support, avoiding the position deviation caused by vibration or external force interference during welding, and ensuring the stability and reliability of the welding process. The wire feeding adjustment module 222 has wide adaptability, whether it is for welding pieces of different sizes, or for welding requirements of different angles and positions, the position and angle of the clamping support 223 can be adjusted to meet the requirements. This adaptability makes the pipe piece welding device widely applicable to various welding scenes and processes, improving the versatility and practicality of the pipe piece welding device. It can be understood that the vertical adjustment assembly 2221 and the horizontal adjustment assembly 2222 in this embodiment can also be adjusted by other means such as automatic telescopic rods, and the angle adjustment assembly 2223 can also be adjusted by other means such as automatic rotating rods.

[0065] In a specific embodiment, the horizontal adjustment assembly 2222 and the angle adjustment assembly 2223 are connected through a telescopic drive 224.

[0066] Specifically, the lower end of the telescopic drive 224 is connected to the horizontal adjustment support 22222, the upper end of the telescopic drive 224 is connected to the rotating shaft 22231, and the driving direction of the telescopic drive 224 is perpendicular to the horizontal optical axis 22221. By controlling the telescopic drive 224 to extend or retract, the position of the clamping support 223 can be fine-tuned in the Y-axis direction, thereby realizing accurate control of the position of the welding wire end, so that the welding wire clamped by the clamping support 223 can accurately flow to the welding position after being heated and melted. This precise control helps to reduce welding errors, improve welding precision and ensure welding quality. It can be understood that the telescopic drive 224 can adopt various driving schemes such as telescopic cylinders and linear motors, so as to realize automatic control, respond to operation instructions faster, improve work efficiency, and at the same time, automatic control can also reduce errors caused by human factors, making the welding process more stable and reliable.

[0067] Referring to Figure 2 and Figure 9As shown, in a specific embodiment, the Y-axis driving module 12 further comprises a second Y-axis driving module 123, which is installed on the Y-axis mounting seat 121 and drivingly connected to the welding mechanism 3, and is used to drive the welding mechanism 3 to move in the Y-axis direction.

[0068] Specifically, by precisely controlling the movement of the second Y-axis driving module 123, the position accuracy of the welding mechanism 3 in the Y-axis direction can be ensured, thereby improving the accuracy and stability of welding. This is particularly important for occasions that require high-precision welding. In the present embodiment, the driving structure and driving direction of the second Y-axis driving module 123 are consistent with those of the first Y-axis driving module 122, which is simple and stable in structure and can realize precise movement control, thereby optimizing the movement path and improving the welding efficiency.

[0069] Referring to Figure 9 As shown, in a specific embodiment, the welding mechanism 3 comprises a mounting support 31, a telescopic driving module 32, an adjusting module 33, and a welding torch 34. The second Y-axis driving module 123 is drivingly connected to the mounting support 31 to drive the mounting support 31 to move in the Y-axis direction. The telescopic driving module 32 and the adjusting module 33 are both installed on the mounting support 31, and the telescopic driving module 32 is drivingly connected to the adjusting module 33. The welding torch 34 is installed on the adjusting module 33. The telescopic driving module 32 is used to drive the adjusting module 33 and the welding torch 34 to move. The adjusting module 33 is used to adjust the position of the welding torch 34.

[0070] Specifically, the adjusting module 33 is used to adjust the height of the welding torch 34, and the driving direction of the telescopic driving module 32 is along the Y-axis, which is consistent with the driving direction of the second Y-axis driving module 123. In the present embodiment, the second Y-axis driving module 123 is drivingly connected to the mounting support 31, and the adjusting module 33 is installed on the mounting support 31, so that the welding torch 34 can accurately reach the welding position through the X-axis driving module 11, the second Y-axis driving module 123, and the adjusting module 33. In combination with the telescopic driving module 32 (whose driving direction is also along the Y-axis), the welding torch 34 can be accurately telescoped and positioned in the Y-axis direction, and in combination with the telescopic driving member 224 drivingly connected to the clamping support 223, the uniform heating of the welding wire and the welding position by the welding torch 34 is realized.

[0071] In a specific embodiment, the adjusting module 33 comprises a connecting seat 331, a support rod 332, and a height adjusting support 333. The connecting seat 331 is slidingly connected to the mounting support 31 and drivingly connected to the telescopic driving module 32. The support rod 332 is vertically installed on the connecting seat 331, and the height adjusting support 333 is slidingly connected to the support rod 332. The adjusting mode of the height adjusting support 333 is consistent with that of the vertical adjusting support 22212, so that the height of the welding torch 34 is easy to adjust, and the welding torch 34 can be stably supported.

[0072] The combination of the X-axis driving module 11, the second Y-axis driving module 123 and the adjusting module 33 ensures that the welding gun 34 can accurately reach the position to be welded, thereby greatly improving the precision and reliability of welding. Meanwhile, the precise telescopic adjusting function of the telescopic driving module 32 in the Y-axis direction enables the welding gun 34 to be flexibly adjusted according to different welding requirements, thereby achieving fine control over the welding process. Since the welding gun 34 can be precisely telescoped and positioned in the Y-axis direction, uniform heating of the position to be welded during the welding process can be ensured, thereby improving the welding quality and efficiency.

[0073] Referring to Figure 2 More specifically, the welding gun 34 is located below the clamping support 223. The vertical layout between the welding gun 34 and the clamping support 223 helps to reduce deviation and error during welding. Since the welding wire is inserted from above between the welding gun 34 and the position to be clamped, precise control over the end of the welding wire can be more easily achieved, thereby improving the precision and stability of welding. Meanwhile, by placing the welding gun 34 below the clamping support 223, interference and collision between the welding gun 34 and other components during welding can be reduced, which helps to protect key components such as the welding gun 34 and the clamping support 223, and a variety of welding requirements can be met by adjusting the positions of the welding gun 34 and the clamping support 223, thereby having higher flexibility.

[0074] Referring to Figure 9 In a specific embodiment, the telescopic driving module 32 includes a swinging driving member 321, a cam 322 and a swinging connecting rod 323, which are sequentially drivingly connected, and the swinging connecting rod 323 is drivingly connected to the adjusting module 33. The swinging driving member 321 drives the cam 322 and the swinging connecting rod 323 to drive the adjusting module 33 and the welding gun 34 to move.

[0075] Specifically, during welding, the swinging driving member 321 drives the cam 322 to rotate, and the cam 322 drives the adjusting module 33 to move back and forth along the Y-axis through the swinging connecting rod 323, thereby driving the welding gun 34 to move back and forth along the Y-axis, to ensure uniform heating of the position to be welded and improve the welding quality. In addition, in the present embodiment, the swinging driving member 321 is a swinging driving motor, which can provide stable and controllable power output, thereby ensuring the accuracy and stability of the swinging movement and facilitating automatic control. It can be understood that in other embodiments, the swinging driving member 321 can also adopt driving schemes such as air cylinders and hydraulic cylinders.

[0076] Referring to Figure 10As shown, in a specific embodiment, two air injection pipes 341 are respectively provided on both sides of the welding gun 34 , and nozzles 342 are provided at the ends of the air injection pipes 341 .

[0077] Specifically, the air jets 341 are arc-shaped, so that during welding, the workpiece 5 to be welded is located between the air jets 341 on both sides, and the four nozzles 342 each correspond to the welding position on the workpiece 5 to be welded, thereby achieving simultaneous welding of multiple points on the workpiece 5 to be welded, significantly reducing the time required for welding, thereby improving welding efficiency, and also helping to reduce thermal stress concentration and welding deformation during the welding process, thereby improving the strength and reliability of the weld. At the same time, driven by the telescopic drive module 32, the four nozzles 342 move back and forth along the Y-axis, further increasing the flexibility of welding, making the welding process more efficient and continuous, ensuring accuracy and consistency during the welding process, thereby improving welding quality, and being able to adapt to workpieces of different shapes and sizes, improving the versatility and flexibility of the welding equipment.

[0078] See also Figure 1 、 Figure 2 and Figure 8 As shown, more specifically, two wire feed modules 21 and two clamping supports 223 are provided to simultaneously supply welding wire to both sides of the workpiece 5 to be welded, corresponding to the nozzle 342, thereby achieving simultaneous welding on both sides. This design significantly improves welding efficiency and ensures that the melted welding wire is evenly distributed around the welded position, not only achieving uniform weld filling but also ensuring a highly flat weld surface. Furthermore, this design promotes even distribution of welding heat across the welded position, effectively avoiding weld deformation and cracking problems that may be caused by excessive heat concentration. This improves welding efficiency while significantly optimizing welding quality.

[0079] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
