Description

Technical Field

[0001] The present invention relates to the field of burner welding, and particularly to a welding device for industrial burner metal components. Background Art

[0002] An industrial burner is a device that converts a substance into heat energy through a combustion chemical reaction and is widely used in the industrial production process. According to its working principle, industrial burners can be classified in various ways such as fuel type, combustion control method, atomization method, and structure. The shell design of industrial burners usually depends on their application requirements and functions, and there are various shapes, including a cylindrical structure. Most of the cylindrical burner shells are welded from two split semi-cylindrical tubes. This design simplifies the manufacturing process, facilitates mass production, and also facilitates the installation and maintenance of other components of the burner inside the shell.

[0003] In the prior art, usually, workers transport the burner shells on the production line to the welding equipment, and then manually limit the positions of the two burner shells before welding. When welding larger semi-cylindrical burner shells, in order to optimize the work process, a fixed welding station and a method of moving the workpiece are mostly used for welding. Therefore, before welding, workers need to accurately align and fix the two burner shells to be welded, and timely change the welding parts of the burner shells during the welding process to achieve the purpose of uniform welding. However, in the actual processing process, it is difficult for workers to accurately align and fix the burner shells, resulting in easy misalignment of the burner shells before welding, affecting the welding effect, and at the same time, the manual replacement of the welding position increases the labor cost in the processing process. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose a welding device for industrial burner metal components.

[0005] To achieve the above object, the technical solution adopted by the present invention is: a welding device for industrial burner metal components, including a support frame, on the inner wall of which an installation frame is horizontally slidably connected through a moving mechanism. Rectangular openings are symmetrically formed at the top of the installation frame. The device further includes:

[0006] Two first electric cylinders, symmetrically and fixedly installed on the top of the support frame, and the end parts of the piston rods of the two first electric cylinders are commonly fixedly connected with a limiting rod;

[0007] Two arc-shaped blocking plates, symmetrically arranged above the installation frame and used for blocking the two burner shells to be welded. Rectangular frames are respectively fixedly connected to the bottom parts of the two arc-shaped blocking plates;

[0008] A pulling mechanism is arranged below the installation frame and is used for pulling two arc-shaped blocking plates to move vertically;

[0009] Two clamping ring plates are used for clamping the side walls of two burner shells. Linkage mechanisms are respectively arranged between the two clamping ring plates and the two rectangular frames. During the downward movement of the two rectangular frames, the two clamping ring plates are automatically driven to move towards each other by means of the two linkage mechanisms, so as to achieve centering adjustment and clamping of the two burner shells;

[0010] A rotating mechanism is arranged on the top of the support frame and is used for driving the two burner shells to rotate to assist in welding;

[0011] A welding head is fixedly arranged on one side of the support frame;

[0012] When welding a larger semi-cylindrical burner housing, in order to optimize the work process, a fixed welding station and a method of moving the workpiece are mostly used for welding. Therefore, before welding, workers need to precisely align and fix the two burner housings to be welded. During the welding process, the welding parts of the burner housing need to be replaced in a timely manner to achieve the purpose of uniform welding. However, in the actual processing process, it is difficult for workers to precisely align and fix the burner housing, resulting in misalignment of the burner housing before welding, which affects the welding effect. At the same time, manually replacing the welding position increases the labor cost during the processing. This technical solution can solve the above problems. The specific implementation method is as follows. When working, the welding equipment is set at the end of the burner housing conveying line. The width of the conveying line can place two oppositely arranged burner housings for conveying. The controller on the welding equipment is controlled externally or installed on the side wall of the support frame. A sensor is set on the support frame. The sensor is used to detect whether a burner housing is conveyed into the welding equipment area. When the sensor detects that the two burner housings on the conveying line are conveyed into the welding support frame, the controller controls the piston rods of the two first electric cylinders to jointly pull the limiting rod downward. The downward-moving limiting rod will push the arc surfaces of the two burner housings, thereby assisting the two burner housings to move from the conveying line to the arc-shaped blocking plate, and at the same time blocking the next group of burner housings to prevent subsequent burner housings from continuously moving onto the welding device along the conveying line. The arc-shaped surfaces of the two arc-shaped blocking plates block the burner housings, thereby blocking the continuous movement of the burner housings. Under the blocking of the upper limiting rod and the two lower arc-shaped blocking plates, it is beneficial to assist the alignment of the openings of the two burner housings. Then, the controller controls the operation of the pulling mechanism. The pulling mechanism will pull the two rectangular frames connected with the arc-shaped blocking plates downward. During the slow downward movement of the arc-shaped blocking plates, first, the two linkage mechanisms drive the two clamping ring plates to move towards each other. With the two clamping ring plates moving towards each other, it is beneficial to push the two burner housings towards the middle, and finally clamp the two burner housings, eliminating the need for workers to spend energy on alignment and limitation. Subsequently, the moving mechanism drives the installation frame to move towards the welding station. After reaching the welding station, the welding head welds the welding parts of the two burner housings, and the rotating mechanism drives the two burner housings to be welded and clamped to rotate, realizing automatic replacement of the welding position, which is beneficial to improving the uniformity of welding.

[0013] Preferably, the moving mechanism includes two first motors, which are symmetrically and fixedly installed on the inner wall of the support frame.

[0019] A fixing block is fixedly connected to the side wall of the sliding seat. The end of the fixing block is rotatably connected to a sliding pin, and the end of the sliding pin is inserted into the guiding rail.

[0020] Preferably, clamping reinforcement mechanisms are respectively arranged on the clamping surfaces of the two clamping ring plates. During the downward movement of the clamping ring plates, the clamping reinforcement mechanisms are also linked to enhance the clamping effect. The clamping reinforcement mechanism includes:

[0021] A cavity is formed inside the clamping plate.

[0022] A plurality of mounting grooves are formed in a circumferential array on the clamping surface of the clamping plate. A suction cup is installed in each mounting groove, and the end of each suction cup is respectively communicated with the inside of the mounting groove through a communication pipe.

[0023] A plurality of first communication ports penetrate through the inner wall of the annular groove and are communicated with the inside of the mounting groove.

[0024] A sealing port includes a second communication port and a third communication port that communicate with each other. The second communication port penetrates through the surface of the rotating ring, and the third communication port penetrates through the bottom of the sliding seat.

[0025] A sealing plate is vertically slidably connected inside the sealing port, and the side wall of the sealing plate is in sealed contact with the inner wall of the sealing port.

[0026] A relief port is formed in the inner wall of the second communication port.

[0027] The telescopic rod is fixedly connected to the side wall of the adjacent rectangular frame, and the end of the piston rod of the telescopic rod is fixedly connected to the bottom of the sealing plate.

[0028] Preferably, the rotating mechanism includes:

[0029] Two connecting frames are respectively fixedly connected to the side walls of the clamping ring plate, and external gear rings are respectively fixedly connected to the surfaces of the two connecting frames;

[0030] Two second motors are symmetrically and fixedly installed on the top of the support frame, and gears are fixedly connected to the ends of the output shafts of the two second motors. The gears are adapted to mesh with the adjacent external gear rings.

[0031] Preferably, a cleaning mechanism is arranged inside the support frame, and during the process of moving the two burner shells towards the welding station, the parts to be welded are automatically cleaned. The cleaning mechanism includes:

[0032] A U-shaped frame is fixedly connected to the inner bottom surface of the support frame. An empty shell is fixedly connected to the top of the U-shaped frame. A cleaning brush is installed at the top opening of the empty shell, and a plurality of feeding ports are formed through the cleaning brush;

[0033] A dust suction unit, and the feeding pipe of the dust suction unit is communicated with the inside of the empty shell;

[0034] Two racks are symmetrically and fixedly connected to the inner wall of the support frame. The two external gear rings are respectively adapted to mesh with the corresponding two racks, and the width of the rack is greater than the width of the external gear ring.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. The controller controls the piston rods of two first electric cylinders to jointly pull the limit rod downward. The downward-moving limit rod will push the arc surfaces of the two burner casings, thereby assisting the two burner casings to move from the conveyor line onto the arc-shaped baffle, while blocking the next set of burner casings to prevent subsequent burner casings from continuously moving onto the welding setting along the conveyor line. The arc-shaped surfaces of the two arc-shaped baffles block the burner casings, thereby blocking the continuous movement of the burner casings. Under the blocking of the upper limit rod and the two lower arc-shaped baffles, it is beneficial to assist the alignment of the orifice openings of the two burner casings. Then, the controller controls the operation of the pulling mechanism, and the pulling mechanism will pull the rectangular frames connected with the arc-shaped baffles downward. During the slow downward movement of the arc-shaped baffles, first, two linkage mechanisms drive the two clamping ring plates to move towards each other. With the help of the two clamping ring plates moving towards each other, it is beneficial to push the two burner casings towards the middle, and finally clamp the two burner casings, eliminating the need for workers to spend energy aligning the limits. Subsequently, the moving mechanism drives the installation frame to move towards the welding station. After reaching the welding station, the welding head performs welding on the welding parts of the two burner casings, and the rotating mechanism drives the two burner casings to be welded and clamped to rotate, realizing automatic replacement of the welding positions, which is beneficial to improving the uniformity of welding.

[0037] 2. During the process of the inner wall of the inclined orifice contacting the surface of the sliding pin, the inclined orifice can pull the clamping ring plate to move towards one side of the burner casing. Finally, the clamping surface of the clamping ring plate contacts and clamps the side wall of the burner casing. And as the rectangular frame continues to move downward, during the process of the vertical orifice contacting the surface of the sliding pin, on the one hand, it maintains the clamping of the side wall of the burner casing by the clamping ring plate, and on the other hand, since the clamping surface of the clamping ring plate clamps the side wall of the burner casing, when the rectangular frame continues to move downward and the sealing plate is pulled downward by the telescopic rod, the sealing plate moving downward along the inner wall of the sealing orifice will drive the air flow inside the cavity to enter the sealing orifice through the first communication port, causing a negative pressure to form inside the suction cup that communicates with the cavity. With the help of the suction cup with negative pressure, it sucks the side wall of the burner casing, thereby assisting the clamping surface of the clamping ring plate to clamp the side wall of the burner casing, which is beneficial to enhancing the clamping effect and improving the stability of clamping during the movement of the burner casing towards the welding station.

[0038] 3. Driven by the rack, the external gear ring will roll along the direction of the rack, thereby driving the two burner casings to be clamped to roll past the cleaning brush bristles. The cleaning brush cleans the impurities and dirt adhering to the welding parts on the burner casing during the rolling process, reducing the impact of dust and impurities on the subsequent welding results. The dust collection unit performs dust suction on the inside of the empty shell through the feed pipe. Under the action of suction, it is beneficial to suck the impurities brushed off through the feed port into the inside of the empty shell, and finally be centrally absorbed by the dust collection unit.

DETAILED DESCRIPTION OF THE INVENTION

[0050] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0051] As Figures 1 to 10 shown, an industrial burner metal component welding device includes a support frame 1. An installation frame 2 is horizontally and slidably connected to the inner wall of the support frame 1 through a moving mechanism. Rectangular openings are symmetrically formed at the top of the installation frame 2. It further includes:

[0052] Two first electric cylinders 3 are symmetrically and fixedly installed at the top of the support frame 1. The end parts of the piston rods of the two first electric cylinders 3 are commonly fixedly connected with a limiting rod 4;

[0053] Two arc-shaped blocking plates 5 are symmetrically arranged above the installation frame 2 and are used to block two burner shells to be welded. Rectangular frames 6 are respectively fixedly connected to the bottoms of the two arc-shaped blocking plates 5;

[0054] A pulling mechanism is arranged below the installation frame 2 and is used to pull the two arc-shaped blocking plates 5 to move vertically;

[0055] Two clamping ring plates 7 are used to clamp the side walls of the two burner shells. Linkage mechanisms are respectively arranged between the two clamping ring plates 7 and the two rectangular frames 6. During the downward movement of the two rectangular frames 6, the two clamping ring plates 7 are automatically driven to move towards each other through the two linkage mechanisms, so as to realize centering adjustment and clamping of the two burner shells;

[0056] A rotating mechanism is arranged on the top of the support frame 1 and is used to drive the two burner shells to rotate for auxiliary welding;

[0057] The welding head 8 is fixedly arranged on one side of the support frame 1. During operation, the welding device is arranged at the end of the burner housing conveying line. The width of the conveying line can accommodate two oppositely arranged burner housings for conveying. The controller on the welding device is controlled externally or installed on the side wall of the support frame 1. A sensor is arranged on the support frame 1, and the sensor is used to detect whether a burner housing is conveyed into the welding device area. When the sensor detects that two burner housings on the conveying line are conveyed into the interior of the welding support frame 1, the controller controls the piston rods of the two first electric cylinders 3 to jointly pull the limiting rod 4 downward. The downward-moving limiting rod 4 will push the arc surfaces of the two burner housings, thereby assisting the two burner housings to move from the conveying line onto the arc-shaped blocking plate 5, and at the same time blocking the next group of burner housings to prevent subsequent burner housings from continuously moving onto the welding device along the conveying line. The arc-shaped surfaces of the two arc-shaped blocking plates 5 block the burner housings, thereby blocking the continuous movement of the burner housings. Under the blocking of the upper limiting rod 4 and the two lower arc-shaped blocking plates 5, it is beneficial to assist the alignment of the openings of the two burner housings. Then, the controller controls the operation of the pulling mechanism, and the pulling mechanism will pull the rectangular frame 6 connected with the two arc-shaped blocking plates 5 downward. During the slow downward movement of the arc-shaped blocking plate 5, first, the two linkage mechanisms drive the two clamping ring plates 7 to move towards each other. With the two clamping ring plates 7 moving towards each other, it is beneficial to push the two burner housings towards the middle, and finally clamp the two burner housings, eliminating the need for workers to align and limit with great effort. Subsequently, the moving mechanism drives the mounting frame 2 to move towards the welding station. After reaching the welding station, the welding head 8 welds the welding parts of the two burner housings, and the rotating mechanism drives the two burner housings to be welded and clamped to rotate, realizing automatic replacement of the welding positions, which is beneficial to improving the welding uniformity.

[0058] As an embodiment of the present invention, the moving mechanism includes two first motors 9, which are symmetrically and fixedly installed on the inner wall of the support frame 1. The end of the output shaft of each first motor 9 is fixedly connected with a screw rod 10. The two screw rods 10 are respectively threadedly connected with the mounting frame 2 through threaded sleeves. By starting the two first motors 9 through the controller, the output shaft of the first motor 9 will drive the screw rod 10 to rotate. The rotating screw rod 10 will drive the mounting frame 2 to slide horizontally along the inner wall of the support frame 1 through the threaded sleeve, thereby conveniently driving the two burner housings to be welded towards the welding station.

[0059] As an embodiment of the present invention, the pulling mechanism includes a second electric cylinder 11. The second electric cylinder 11 is fixedly installed at the bottom of the installation frame 2. The end of the piston rod of the second electric cylinder 11 penetrates through the installation frame 2 and extends into its interior, and is fixedly connected to a connecting plate 12. The lower ends of the two rectangular frames 6 respectively pass through the two rectangular openings and extend downward into the interior of the installation frame 2. Both of the two rectangular frames 6 are fixedly connected to the connecting plate 12. During operation, the controller controls the operation of the second electric cylinder 11. The piston rod of the second electric cylinder 11 will pull the connecting plate 12 downward. The two rectangular frames 6 connected with the arc-shaped blocking plates 5 are driven by the downward-moving connecting plate 12 to move downward, so as to gradually pull the arc-shaped blocking plates 5 to cancel the contact blockage of the two aligned burner housings. Therefore, when driving the two burner housings to rotate, it is beneficial to reduce the contact friction generated by contacting with the arc-shaped blocking plates 5, facilitating the smooth rotation of the burner housings.

[0060] As an embodiment of the present invention, the linkage mechanism includes:

[0061] A guiding rail is formed by obliquely opening a through hole in the side wall of the rectangular frame 6, and the guiding rail is jointly composed of an obliquely opening 13 and a vertically opening 14 that are interconnected;

[0062] An annular groove 15 is formed on the surface of the clamping ring plate 7. A rotating ring 16 is rotatably connected to the inner wall of the annular groove 15, and the side wall of the rotating ring 16 is in sealed contact with the inner wall of the annular groove 15;

[0063] A sliding seat 17 is fixedly connected to the surface of the rotating ring 16, and the sliding seat 17 is horizontally slidably connected to the inner wall of the adjacent rectangular opening;

[0064] The fixed block 18 is fixedly connected to the side wall of the sliding seat 17. A sliding pin 19 is rotatably connected to the end of the fixed block 18, and the end of the sliding pin 19 is inserted into the inside of the guide rail. During operation, when the pulling mechanism pulls the rectangular frame 6 to drive the arc-shaped blocking plate 5 to gradually move downward, the inner wall of the inclined port 13 will push the surface of the sliding pin 19 inserted therein, thereby causing the sliding pin 19 to pull the fixed block 18 to move. The moving fixed block 18 pulls the sliding seat 17 connected with the rotating ring 16 to move horizontally along the inner wall of the rectangular port. And under the pulling of the rotating ring 16 on the wall of the annular groove 15 on the surface of the clamping ring plate 7, the sliding seat 17 drives the clamping ring plate 7 to move while moving. Therefore, during the downward movement of the two rectangular frames 6, the two clamping ring plates 7 will be driven to move towards each other, push the two burner shells after aligning the shell ports towards the middle, and finally automatically clamp the side walls of the two burner shells, so as to facilitate driving the burner shells to move towards the welding station. As the rectangular frame 6 continues to move downward, the inner wall of the vertically opened port 14 will contact the surface of the sliding pin 19. During this process, it is convenient to maintain the stability of the clamping state of the two clamping ring plates 7 on the two burner shells. When the upper end of the vertical port 14 contacts the surface of the sliding pin 19, it indicates that the rectangular frame 6 drives the arc-shaped blocking plate 5 to stop moving downward, and the arc surface of the arc-shaped blocking plate 5 is completely separated from the surface of the burner shell, avoiding the situation that the clamping effect is affected by friction during the movement of the burner shell towards the welding station.

[0065] As an embodiment of the present invention, clamping strengthening mechanisms are respectively arranged on the clamping surfaces of the two clamping ring plates 7. During the downward movement of the clamping ring plates 7, the clamping strengthening mechanisms will also be driven to strengthen the clamping effect. The clamping strengthening mechanism includes:

[0066] A cavity 20 is opened inside the clamping plate;

[0067] A plurality of mounting grooves 21 are arranged in a circumferential array on the clamping surface of the clamping plate. A suction cup 22 is installed inside each mounting groove 21, and the end of each suction cup 22 is respectively communicated with the inside of the mounting groove 21 through a communicating pipe;

[0068] A plurality of first communication ports 23 are penetrated and opened on the inner wall of the annular groove 15 and are communicated with the inside of the mounting groove 21;

[0069] The sealing port includes a second communication port 24 and a third communication port 25 that are communicated with each other. The second communication port 24 is penetrated and opened on the surface of the rotating ring 16, and the third communication port 25 is penetrated and opened at the bottom of the sliding seat 17;

[0070] A sealing plate 26 is vertically slidably connected inside the sealing port, and the side wall of the sealing plate 26 is in sealing contact with the inner wall of the sealing port;

[0071] A clearance opening 27 is provided on the inner wall of the second communication opening 24;

[0072] The telescopic rod 28 is fixedly connected to the side wall of the adjacent rectangular frame 6, and the piston rod end of the telescopic rod 28 is fixedly connected to the bottom of the sealing plate 26; during operation, when the inner wall of the oblique opening 13 contacts the surface of the sliding pin 19, the clamping ring plate 7 can be pulled to one side of the burner housing through the oblique opening 13 to move, and finally the clamping surface of the clamping ring plate 7 contacts and clamps the side wall of the burner housing, and as the rectangular frame 6 continues to move downward, the vertical opening 14 contacts the surface of the sliding pin 19, on the one hand, the clamping of the clamping ring plate 7 on the side wall of the burner housing is maintained, and on the other hand, the clamping surface of the clamping ring plate 7 and the side wall of the burner housing are clamped. Therefore, when the rectangular frame 6 continues to move downward and the sealing plate 26 is pulled downward by the telescopic rod 28, the sealing plate 26 moving downward along the inner wall of the sealing port will drive the airflow inside the cavity 20 to enter the sealing port through the first connecting port 23, so that a negative pressure is formed inside the suction cup 22 which is interconnected with the cavity 20. The suction cup 22 that forms the negative pressure is used to suck the side wall of the burner shell, thereby assisting the clamping of the clamping ring plate 7 to clamp the side wall of the burner shell, which is beneficial to enhance the clamping effect and improve the stability of the clamping during the movement of the burner shell to the welding station; the telescopic rod 28 can be adaptively extended and retracted according to the lateral movement of the sliding seat 17.

[0073] As an embodiment of the present invention, the rotating mechanism includes:

[0074] Two connecting frames 29 are respectively fixedly connected to the side walls of the clamping ring plate 7, and the surfaces of the two connecting frames 29 are respectively fixedly connected with outer gear rings 30;

[0075] The two second motors 32 are symmetrically fixedly installed on the top of the support frame 1, and the output shaft ends of the two second motors 32 are fixedly connected with gears 33, and the gears 33 are adapted to mesh with the adjacent outer gear rings 30; when working, when the installation frame 2 drives the two clamped burner shells to reach the welding station, the outer gear rings 30 connected to the two connecting frames 29 are respectively meshed with the two gears 33, and then the two second motors 32 are controlled to operate, and the output shafts of the second motors 32 will drive the gears 33 to rotate, and the two outer gear rings 30 are driven to rotate under the transmission of the gears 33, so that the two burner shells are driven to rotate at the welding station with the help of the two clamping ring plates 7, and the welding position during the welding process is replaced, so as to facilitate the welding head 8 to perform comprehensive and uniform welding on the parts of the two burner shells that need to be welded.

[0076] As an embodiment of the present invention, a cleaning mechanism is provided inside the support frame 1, and the parts to be welded are automatically cleaned during the movement of the two burner shells to the welding station. The cleaning mechanism includes:

[0077] The U-shaped frame 34 is fixedly connected to the inner bottom surface of the support frame 1. A hollow shell 35 is fixedly connected to the top of the U-shaped frame 34. A cleaning brush 36 is installed at the top opening of the hollow shell 35. A plurality of feed ports are penetrated and opened on the cleaning brush 36;

[0078] A dust suction unit, the feed pipe of the dust suction unit is communicated with the inside of the hollow shell 35;

[0079] Two racks 31 are symmetrically and fixedly connected to the inner wall of the support frame 1. Two outer gear rings 30 are respectively adapted to mesh with the corresponding two racks 31. The width of the rack 31 is greater than the width of the outer gear ring 30. During operation, the width of the rack 31 is set to be greater than the width of the outer gear ring 30. The purpose is to facilitate the outer gear ring 30 to always maintain the meshing state with the rack 31 during the process of the two clamping ring plates 7 moving towards each other for clamping in the initial state. After the mounting frame 2 clamps the burner housing with the two clamping ring plates 7 and moves towards the welding station, the outer gear ring 30 will roll along the direction of the rack 31 under the drive of the rack 31, thereby driving the two clamped burner housings to roll past the bristles of the cleaning brush 36. The cleaning brush 36 cleans the impurities and dirt adhered to the welding parts on the rolling burner housing, reducing the influence of dust and impurities on the subsequent welding results. The dust suction unit sucks the inside of the hollow shell 35 through the feed pipe. Under the action of suction, it is beneficial to suck the impurities brushed off through the feed port into the hollow shell 35, and finally be centrally absorbed by the dust suction unit. When the rolling outer gear ring 30 disengages from the meshing with the rack 31, the cleaning brush 36 completes the cleaning of one circle of the burner housing, and the outer gear ring 30 continues to move with the mounting frame 2 to mesh with the gear 33 and stops.

[0080] Working principle of the present invention: The welding device is arranged at the end of the conveyor line of the burner housing. The width of the conveyor line can accommodate two oppositely arranged burner housings for conveying. The controller on the welding device is controlled externally or installed on the side wall of the support frame 1. A sensor is arranged on the support frame 1, and the sensor is used to detect whether a burner housing is conveyed into the welding device area. When the sensor detects that two burner housings on the conveyor line are conveyed into the interior of the welding support frame 1, the controller controls the piston rods of the two first electric cylinders 3 to jointly pull the limiting rod 4 downward. The downward-moving limiting rod 4 will push the arc surfaces of the two burner housings, thereby assisting the two burner housings to move from the conveyor line onto the arc-shaped baffle 5, and at the same time blocking the next group of burner housings to prevent subsequent burner housings from continuously moving onto the welding device along the conveyor line. The arc-shaped surfaces of the two arc-shaped baffles 5 block the burner housings, thereby blocking the continuous movement of the burner housings. Under the blocking of the upper limiting rod 4 and the two lower arc-shaped baffles 5, it is beneficial to assist the alignment of the openings of the two burner housings. Then, the controller controls the operation of the pulling mechanism, and the pulling mechanism will pull the rectangular frames 6 connected with the two arc-shaped baffles 5 downward. During the slow downward movement of the arc-shaped baffles 5, first, the two linkage mechanisms drive the two clamping ring plates 7 to move towards each other. With the two clamping ring plates 7 moving towards each other, it is beneficial to push the two burner housings towards the middle, and finally clamp the two burner housings, eliminating the need for workers to spend energy on alignment and limiting. Subsequently, the moving mechanism drives the installation frame 2 to move towards the welding station. After reaching the welding station, the welding head 8 performs welding treatment on the welding parts of the two burner housings, and the rotating mechanism drives the two burner housings to be welded and clamped to rotate, realizing automatic replacement of the welding positions, which is beneficial to improving the uniformity of welding.
