Description

Technical Field

[0001] The present application relates to the field of transformer welding technology, and in particular to a welding device for transformer production. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. In electrical equipment and wireless circuits, it is often used to increase or decrease voltage, match impedance, and provide safety isolation. Transformers can be divided into two categories according to the cooling method: dry-type transformers and oil-immersed transformers. Among them, an oil-immersed transformer refers to a transformer that uses transformer oil as a cooling and insulating medium. It mainly includes components such as an iron core, windings, an oil tank, an oil pillow, an insulating sleeve, a radiator, a tap changer, and a gas relay. The windings and the iron core are installed in an oil tank filled with transformer oil. The oil tank is welded with steel plates, and the radiator is welded around the oil tank. The radiator is composed of a number of evenly arranged heat pipes in a U shape. Two sets of holes arranged up and down are also opened around the oil tank for inserting and welding the heat pipes.

[0003] With respect to the above-mentioned related technologies, the inventors found that before workers weld the heat dissipation pipe and the fuel tank, they usually insert the heat dissipation pipe into the corresponding hole of the fuel tank first, knock the heat dissipation pipe a few times with a hammer to fix it in the hole first, and then weld the fixing part of the heat dissipation pipe. On the one hand, this is to fix the heat dissipation pipe first to facilitate welding, and on the other hand, it is also to make the heat dissipation pipe and the inner wall of the hole corresponding to the fuel tank body press tightly, thereby improving the tightness of the connection between the fuel tank and the heat dissipation pipe. However, since multiple heat dissipation pipes need to be welded on each fuel tank, workers have to repeat the knocking and welding operations for each heat dissipation pipe, resulting in low production efficiency and a large workload for workers. Summary of the invention

[0004] In order to improve the efficiency of welding transformer heat dissipation pipes and reduce the workload of workers, the present application provides a welding device for transformer production.

[0005] The present application provides a welding device for transformer production using the following technical solution:

[0006] A welding device for transformer production, comprising a first fixing component, a hammering component, a welding component, a loading robot and a unloading robot, wherein the first fixing component comprises two groups of clamping members, the two groups of clamping members are used to clamp an oil tank, and the two groups of clamping members are rotatable, a first guide rail is arranged on the ground, the first fixing component is slidably connected to the first guide rail, and the loading robot, the hammering component, the welding component and the unloading robot are arranged in sequence along the length direction of the first guide rail.

[0007] By adopting the above technical solution, before welding the heat dissipation pipe on the oil tank, the first fixing component first slides to the bottom of the loading robot, the loading robot clamps the oil tank and places it on the first fixing component, and makes the side of the oil tank to be welded with the heat dissipation pipe face upward, the two sets of clamps clamp and fix the oil tank, at this time, the worker first inserts the heat dissipation pipe on the upper side of the oil tank into the hole on the oil tank, and then the first fixing component transports the oil tank to the bottom of the hammering component, the hammering component automatically knocks the two ends of the heat dissipation pipe, so that the heat dissipation pipe is tightly inserted into the hole on the oil tank, and then the first fixing component transports the oil tank that has passed the fixed heat dissipation pipe to the bottom of the welding component, and the welding component automatically welds the connection between the two ends of the heat dissipation pipe and the oil tank;

[0008] After welding is completed, the first fixing component drives the oil tank to be transported to the bottom of the hammering component again. During the transportation process, the two sets of clamps drive the oil tank to flip 90 degrees, so that the side of the oil tank that needs to be welded with the heat dissipation pipe faces upward. At this time, the previous operation is repeated, that is, the worker plugs in the heat dissipation pipe on this side, and then the hammering component hits the heat dissipation pipe. After fixing it, the first fixing component transports the oil tank to the bottom of the welding component for welding... This cycle is repeated until the heat dissipation pipes are all welded around the oil tank. At this time, the first fixing component transports the welded oil tank to the bottom of the unloading robot, and the two sets of clamps release the oil tank. The unloading robot clamps the welded oil tank to the unloading position. At the same time, the first fixing component slides to the bottom of the loading robot, and the loading robot clamps the new oil tank for loading, and the above operation is repeated;

[0009] During this process, workers only need to plug in the heat dissipation pipes around the oil tank, hammering and fixing the heat dissipation pipes are completed by the hammering assembly, welding the heat dissipation pipes and the oil tank are completed by the welding assembly, and the first fixing assembly transfers the oil tank, which greatly saves time, improves the efficiency of welding the transformer heat dissipation pipes, and reduces the workload of workers.

[0010] Optionally, it also includes a second fixed component, a second guide rail is arranged on the ground, the length direction of the second guide rail is arranged parallel to the length direction of the first guide rail, the second fixed component is slidably connected to the second guide rail, and the second fixed component also includes two groups of clamps, the two groups of clamps are used to clamp the oil tank, when the first fixed component is located below the hammering component, the second fixed component is located below the welding component.

[0011] By adopting the above technical solution, the second fixed component is also used to clamp and transfer the oil tank. When the oil tank on the first fixed component is located under the hammering component for hammering operation, the oil tank on the second fixed component is moved to the bottom of the welding component for welding operation, so that the hammering component and the welding component are always in working state, and two oil tanks can be manufactured at the same time, which further improves the efficiency of welding the transformer heat dissipation pipe, thereby improving the efficiency of transformer production.

[0012] Optionally, two second guide rails are provided, the first guide rail is located between the two second guide rails, the first fixed assembly includes a base, a first lifting cylinder is provided on the base, the first lifting cylinder is vertically arranged with the telescopic shaft facing upward, a first support frame is provided on the top of the telescopic shaft of the first lifting cylinder, the clamping member is provided above the first support frame, the second fixed assembly includes two support rods, a second support frame is provided between the two support rods, two groups of clamping members of the second fixed assembly are provided above the second support frame, and the width of the first fixed assembly is smaller than the width between the two support rods.

[0013] By adopting the above technical solution, during the process of the first fixed component and the second fixed component sliding toward each other, the first lifting cylinder contracts, driving the first support frame to descend, thereby driving the oil tank thereon to descend, and because the width of the first fixed component is smaller than the width between the two support rods, the first fixed component can pass under the second support frame, so that the first fixed component and the second fixed component can be transported at the same time; after the first fixed component passes through, the first telescopic cylinder extends, driving the first support frame back to the initial height, so as to facilitate hammering or welding operations.

[0014] Optionally, the clamping member includes a rotating motor, the transmission shaft of the rotating motor is axially horizontally arranged and perpendicular to the length direction of the first guide rail, the transmission shaft of the rotating motor is arranged toward another clamping member of the same group and a clamping cylinder is coaxially fixedly connected to the transmission shaft, a clamping plate is fixedly connected to the telescopic rod of the clamping cylinder, and the two clamping plates are used to clamp the oil tank.

[0015] By adopting the above technical solution, when it is necessary to flip the oil tank, the rotating motor is started, and the rotating motor drives the clamping plate to rotate. The two clamping plates clamp the top opening and the bottom of the oil tank respectively and rotate. At this time, the first lifting cylinder extends or contracts accordingly, driving the first support frame to rise or fall, thereby realizing the flipping of the oil tank; when it is necessary to clamp or release the oil tank, the clamping cylinder extends or contracts to clamp or release the oil tank, thereby facilitating loading or unloading.

[0016] Optionally, the second fixed assembly also includes two second lifting cylinders, the two support rods are hollow inside, the two second lifting cylinders are respectively located in the two support rods, the second lifting cylinders are vertically arranged with the telescopic shafts facing upward, and the second support frame is fixedly connected between the tops of the telescopic shafts of the two second lifting cylinders.

[0017] By adopting the above technical solution, when the oil tank on the second fixed assembly needs to be flipped, the two groups of clamping parts clamp the oil tank and rotate, and the second lifting cylinder extends or contracts accordingly, driving the second support frame to rise or fall, thereby completing the flipping of the oil tank.

[0018] Optionally, the hammering assembly includes a hammering support seat, on which a third lifting cylinder is arranged. The telescopic shaft of the third lifting cylinder is arranged upward, and the top of the telescopic shaft is rotatably connected with a driving rod. The other end of the driving rod is fixedly connected with a hammer head. A third driving motor is arranged on the third lifting cylinder. A driving disk is coaxially and fixedly connected to the transmission shaft of the third driving motor. A driving column is eccentrically arranged on the driving disk. A sliding groove is formed in the driving rod along its length direction, and the driving column is inserted into the sliding groove.

[0019] By adopting the above technical solution, when knocking the heat dissipation pipe, start the third driving motor. The third driving motor drives the driving disk to rotate. The driving disk drives the driving column to rotate around the center of the driving disk, thereby driving the driving rod to rotate up and down. The driving rod drives the hammer head to move up and down, thereby knocking the connection between the two ends of the heat dissipation pipe and the fuel tank, so that the heat dissipation pipe is forced into the fuel tank to complete the fixation of the heat dissipation pipe.

[0020] Optionally, the hammer head is set in a "工" shape. When the two ends of the hammer head are respectively in contact with the top surfaces of the two ends of the heat dissipation pipe, the middle position of the hammer head is arranged at an interval from the heat dissipation pipe.

[0021] By adopting the above technical solution, the hammer head is set in a "工" shape. On the one hand, it can accurately knock the two ends of the heat dissipation pipe. On the other hand, it can reduce the weight of the hammer head, making it easy for the driving rod to be driven to rotate up and down. And when the two ends of the hammer head partially contact the heat dissipation pipe, the middle part is arranged at an interval from the heat dissipation pipe, avoiding knocking the middle part of the heat dissipation pipe and damaging the heat dissipation pipe, thus protecting the heat dissipation pipe.

[0022] Optionally, the welding assembly includes a welding support seat, on which a fourth lifting cylinder is arranged. The top of the telescopic shaft of the fourth lifting cylinder is provided with a welding arm. An installation plate is arranged at the end of the welding arm away from the fourth lifting cylinder. A welding torch is rotatably connected below the installation plate. The nozzle of the welding torch can rotate circumferentially along the end of the heat dissipation pipe. The welding torch is used to heat the solder. The bottom of the nozzle of the welding torch is communicated with a solder ring. The solder ring is set as a semi-ring, and the inside of the solder ring is hollow. The solder ring abuts against the side wall of the end of the heat dissipation pipe. A plurality of material guiding grooves are formed on the side of the solder ring facing the heat dissipation pipe.

[0023] By adopting the above technical solution, when the first fixing component or the second fixing component drives the fuel tank to slide below the welding arm, the nozzle of the welding torch rotates circumferentially along the end of the heat dissipation pipe. Since the heat dissipation pipe blocks the welding torch, the nozzle of the welding torch cannot rotate completely around the end face of the heat dissipation pipe. Therefore, by setting the solder ring, the welding torch can drive the solder ring to rotate around the end of the heat dissipation pipe. During the rotation of the solder ring, the liquid solder flows out from the material guiding grooves, thereby completing the welding of the end of the heat dissipation pipe for one week. At the same time, a plurality of material guiding grooves can flow out the solder at the same time, which can accelerate the welding of the heat dissipation pipe and improve the efficiency of welding the heat dissipation pipe.

[0024] Optionally, two welding guns are provided, and the two welding guns are respectively provided at two ends of a heat dissipation tube, and a welding gun driving motor is provided on the mounting plate. A rotating rod is coaxially fixedly connected to the transmission shaft of the welding gun driving motor, and a connecting rod is fixedly connected to the bottom of the rotating rod, and the other end of the connecting rod is fixedly connected to the top of a welding gun. The straight line where the axis of the rotating rod is located passes through the center of a circle of an end face of the heat dissipation tube, and the top of the other welding gun is also eccentrically connected to the rotating rod through the connecting rod, and the top of the rotating rod is rotatably connected to the bottom surface of the mounting plate, and transverse pulleys are coaxially fixedly connected to the two rotating rods, and the two transverse pulleys are connected by belts.

[0025] By adopting the above technical solution, the welding gun driving motor drives the rotating rod connected to it to rotate, and the rotating rod drives the welding gun to rotate around the axis of the rotating rod through the connecting rod, thereby driving the solder ring to rotate circumferentially along the end of the heat dissipation tube to complete the welding of the end of the heat dissipation tube for one circle; at the same time, the rotating rod drives another rotating rod to rotate through the belt, and the other rotating rod drives another welding gun to rotate along the axis of the rotating rod, thereby driving another solder ring to rotate circumferentially along the other end of the heat dissipation tube to complete the welding of the other end of the heat dissipation tube for one circle, thereby completing the welding of the two ends of a heat dissipation tube at the same time, thereby improving the welding efficiency.

[0026] Optionally, the welding guns are provided in multiple groups, each group of the welding guns includes two welding guns, which are respectively provided at the two ends of a heat dissipation pipe, and the multiple groups of welding guns are arranged along the length direction of the first guide rail. The tops of the two welding guns in each group are eccentrically connected to a rotating rod through a connecting rod, and the rotating rods on the two welding guns in each group are coaxially fixedly connected to a transverse pulley and connected through a belt. A longitudinal pulley is coaxially fixedly connected to the transmission shaft of the welding gun drive motor, and a longitudinal pulley is coaxially fixedly connected to the rotating rod on the top of the welding gun close to the welding gun drive motor in each group, and the longitudinal pulley of the welding gun drive motor is connected to the longitudinal pulley of each group of welding guns through a belt.

[0027] By adopting the above technical solution, multiple groups of welding guns are provided, and the welding gun drive motor drives one welding gun in each group to rotate through the longitudinal pulley, and one welding gun drives another welding gun in the same group to rotate through the belt, thereby realizing the welding of multiple heat dissipation tubes at the same time, greatly improving the welding efficiency; at the same time, multiple groups of welding guns are driven to rotate by one welding gun drive motor, thereby improving the utilization rate of the welding gun drive motor and saving energy.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. Before welding the heat dissipation pipe on the oil tank, the first fixing component first slides to the bottom of the feeding robot. The feeding robot clamps the oil tank and places it on the first fixing component, and makes the side of the oil tank to be welded with the heat dissipation pipe face upward. The two sets of clamps clamp and fix the oil tank. At this time, the worker first inserts the heat dissipation pipe on the upward side of the oil tank into the hole on the oil tank. Then the first fixing component transports the oil tank to the bottom of the hammering component. The hammering component automatically knocks the two ends of the heat dissipation pipe so that the heat dissipation pipe is tightly inserted into the hole on the oil tank. Then the first fixing component transports the oil tank that has passed the fixed heat dissipation pipe to the bottom of the welding component. The welding component automatically welds the connection between the two ends of the heat dissipation pipe and the oil tank.

[0030] After welding is completed, the first fixing component drives the oil tank to be transported to the bottom of the hammering component again. During the transportation process, the two sets of clamps drive the oil tank to flip 90 degrees, so that the side of the oil tank that needs to be welded with the heat dissipation pipe faces upward. At this time, the previous operation is repeated, that is, the worker plugs in the heat dissipation pipe on this side, and then the hammering component hits the heat dissipation pipe. After fixing it, the first fixing component transports the oil tank to the bottom of the welding component for welding... This cycle is repeated until the heat dissipation pipes are all welded around the oil tank. At this time, the first fixing component transports the welded oil tank to the bottom of the unloading robot, and the two sets of clamps release the oil tank. The unloading robot clamps the welded oil tank to the unloading position. At the same time, the first fixing component slides to the bottom of the loading robot, and the loading robot clamps the new oil tank for loading, and the above operation is repeated;

[0031] In this process, workers only need to plug in the heat dissipation pipes around the oil tank, hammering and fixing the heat dissipation pipes are completed by the hammering assembly, welding the heat dissipation pipes and the oil tank is completed by the welding assembly, and the first fixing assembly transfers the oil tank, which greatly saves time, improves the efficiency of welding the heat dissipation pipes of the transformer, and reduces the workload of workers;

[0032] 2. The second fixing assembly is also used to clamp and transfer the oil tank. When the oil tank on the first fixing assembly is located under the hammering assembly for hammering operation, the oil tank on the second fixing assembly is moved to the bottom of the welding assembly for welding operation, so that the hammering assembly and the welding assembly are always in working state, and two oil tanks can be manufactured at the same time, which further improves the efficiency of welding the heat dissipation pipe of the transformer, thereby improving the efficiency of producing the transformer;

[0033] 3. When the first fixing assembly or the second fixing assembly drives the oil tank to slide under the welding arm, the welding gun nozzle rotates circumferentially along the end of the heat dissipation tube. Since the heat dissipation tube blocks the welding gun, the welding gun nozzle cannot fully rotate along the end surface of the heat dissipation tube. Therefore, by setting a solder ring, the spray gun can drive the solder ring to rotate along the end of the heat dissipation tube. During the rotation of the solder ring, liquid solder flows out of the material guide groove, thereby completing the welding of the end of the heat dissipation tube for one circle; at the same time, multiple material guide grooves can flow out solder at the same time, which can accelerate the welding of the heat dissipation tube and improve the efficiency of welding the heat dissipation tube.

[0041] The following is combined with Figure 1-6This application is described in further detail.

[0042] The embodiment of the present application discloses a welding device for transformer production.

[0043] Reference Figure 1 A welding device for transformer production includes a first fixed component 1, a second fixed component 2, a hammering component 5, a welding component 6, a loading robot 7 and a unloading robot 8. The first fixed component 1 and the second fixed component 2 are both used to fix the transformer oil tank 91, a first guide rail component 3 and a second guide rail component 4 are arranged on the ground, the first guide rail component 3 and the second guide rail component 4 are arranged in parallel, and the first guide rail component 3 is located between the second guide rail component 4, the first fixed component 1 is slidably connected to the first guide rail component 3, the second fixed component 2 is slidably connected to the second guide rail component 4, and the first fixed component 1 can be raised and lowered. The hammering component 5 and the welding component 6 are located on the same side of the second guide rail component 4, and are arranged at intervals along the length direction of the second guide rail component 4. The loading robot 7 and the unloading robot 8 are located on the other side of the second guide rail component 4, and the loading robot 7, the hammering component 5, the welding component 6 and the unloading robot 8 are arranged at intervals along the loading direction.

[0044] When in the initial state, the second fixed assembly 2 is located at the rear of the first fixed assembly 1 along the feeding direction. When welding the radiating pipe 92 and the fuel tank 91, the feeding robot 7 clamps the fuel tank 91, and the first fixed assembly 1 moves to the bottom of the feeding robot 7, and the feeding robot 7 places the fuel tank 91 on the first fixed assembly 1, and the first fixed assembly 1 fixes the fuel tank 91 and transports it to the bottom of the hammering assembly 5. At this time, the worker only needs to insert the radiating pipe 92 on one side of the fuel tank 91 into the corresponding hole, and then start the hammering assembly 5, and the hammering assembly 5 hammers the radiating pipe 92 on one side of the fuel tank 91 and the connection between the fuel tank 91, so that the radiating pipe 92 is fixed in the hole. After the radiating pipe 92 is fixed, the first fixed assembly 1 slides to the bottom of the welding assembly 6 again, and the welding assembly 6 welds the radiating pipe 92 on one side of the fuel tank 91 that has been fixed.

[0045] During the welding process, the loading robot 7 clamps the second oil tank 91 again, and then the second fixed component 2 moves to the bottom of the loading robot 7. The loading robot 7 places the second oil tank 91 on the second fixed component 2, and the worker inserts the heat dissipation pipe 92 on one side of the second oil tank 91. The hammering component hammers the heat dissipation pipe 92 on one side of the second oil tank 91 to fix it in the hole on the oil tank 91. When the hammering is completed, the second fixed component 2 slides toward the welding component 6. At the same time, the heat dissipation pipe 92 on one side of the oil tank 91 on the first fixed component 1 has been welded. The first fixed component 1 slides toward the hammering component 5 again, and the second fixed component 2 and the first fixed component 1 slide toward each other. The height of the first fixed component 1 decreases while sliding, and it can pass under the second fixed component 2. At the same time, the first fixed component 1 rotates the oil tank 91 ninety degrees.

[0046] When the first fixed component 1 slides to the bottom of the hammering component 5 again, the worker inserts the heat pipe 92 on the upward side of the fuel tank 91, and then the hammering component 5 hammers the heat pipe 92 on this side to fix it in the fuel tank 91. After hammering, the first fixed component 1 slides toward the welding component 6 again, and at this time the heat pipe 92 on one side of the fuel tank 91 on the second fixed component 2 has been welded. The second fixed component 2 slides toward the hammering component 5 and turns the fuel tank 91 over ninety degrees. When sliding to the bottom of the hammering component 5, the worker inserts the heat pipe 92 on the upward side of the fuel tank 91, and the hammering component 5 hammers again... This cycle is repeated until the heat pipes 92 are welded on all sides of the two fuel tanks 91. The welded fuel tank 91 slides with the first fixed component 1 or the second fixed component 2 to the bottom of the unloading robot 8, and the unloading robot 8 clamps it for unloading. Then the first fixed component 1 or the second fixed component 2 slides to the bottom of the loading robot 7, and the loading robot 7 clamps the new fuel tank 91 for loading, and the above operation is repeated. During this process, workers only need to plug in the heat dissipation pipe 92 on each side of the oil tank 91, and the hammering and welding operations can be completed automatically. The oil tank 91 is continuously transferred by the first fixing component 1 and the second fixing component 2, which greatly saves time, improves the efficiency of welding the transformer heat dissipation pipe 92, and reduces the workload of workers.

[0047] Reference Figure 1 and Figure 2The first fixed assembly 1 includes a lifting seat 11, a first support frame 12 and two groups of clamping members 13. The first support frame 12 is fixedly connected to the top of the lifting seat 11. The two groups of clamping members 13 are arranged on the top of the first support frame 12 and are arranged opposite to each other, and the symmetry plane is arranged vertically and parallel to the length direction of the first guide rail assembly 3.

The first support frame 12 is welded to the top surface of the top plate 114, and the clamping member 13 includes a rotating motor 131 and a clamping cylinder 132. The rotating motor 131 is fixedly connected to the top surface of the first support frame 12. A fixed plate 133 is coaxially fixedly connected to the transmission shaft of the rotating motor 131, and the transmission shaft is arranged toward another set of clamping members 13. The clamping cylinder 132 is coaxially fixedly connected to the side of the fixed plate 133 facing another clamping assembly, and a clamping plate 134 is fixedly connected to the end of the telescopic shaft of the clamping cylinder 132. When the two sets of clamping members 13 clamp the oil tank 91, one clamping plate 134 is pressed against the top of the oil tank 91 without welding the heat dissipation pipe 92, and the other clamping plate 134 is pressed against the bottom of the oil tank 91 without welding the heat dissipation pipe 92.

[0048] When the oil tank 91 needs to be turned over, the rotating motor 131 is started, and the rotating motor 131 drives the clamping plate 134 to rotate. The two clamping plates 134 clamp the oil tank 91 and rotate. At this time, the first lifting cylinder 113 extends or contracts accordingly, driving the first support frame 12 to rise or fall, thereby realizing the turning of the oil tank 91. When the first fixing component 1 needs to pass under the second fixing component 2, the first lifting cylinder 113 contracts, thereby lowering the height of the first fixing component 1 so that it can pass under the second fixing component 2.

[0049] Reference Figure 1 and Figure 2The first guide rail assembly 3 includes a first guide rail 31, a first drive motor 32 and a first lead screw 33. The first lead screw 33 is rotatably connected to the first guide rail 31. The axial direction of the first lead screw 33 is parallel to the length direction of the first guide rail 31. The first drive motor 32 is fixedly connected to one end of the first guide rail 31 and the transmission shaft of the first drive motor 32 is coaxially fixedly connected to the first lead screw 33.

A group of clamping members 13 are arranged on the tops of the two support rods 21, and the two groups of clamping members 13 are arranged oppositely. The structure of the two groups of clamping members 13 is consistent with the structure of the clamping members 13 of the first fixed assembly 1, and no further description is given here. When it is necessary to flip the oil tank 91, the rotating motor 131 is started, and the rotating motor 131 drives the clamping plate 134 to rotate.

[0053] Reference Figure 2 In order to accurately knock the two ends of the radiating pipe 92, the hammering head 54 is set to the shape of "I", and the height of the middle part is less than the height of the two end parts. When the two end parts of the hammering head 54 contact the radiating pipe 92, the middle part and the radiating pipe 92 are arranged at intervals, avoiding knocking the middle part of the radiating pipe 92 and damaging the radiating pipe 92, and simultaneously can also reduce the weight of the hammering head 54 as a whole, so that the driving rod 53 is easily driven to realize the up and down rotation.

The direction adjustment motor 652 is axially parallel to the length direction of the first guide rail 31. The transmission shaft of the direction adjustment motor 652 is coaxially fixedly connected to a rotating shaft 653. The other end of the rotating shaft 653 is rotatably connected to the top of the telescopic shaft of the fourth lifting cylinder 62. One end of the welding arm 63 is fixedly connected to the rotating shaft 653. The welding gun 641 is located at the other end of the welding arm 63. The direction adjustment motor 652 is used to drive the welding arm 63 to rotate. The rotation plane of the welding arm 63 is parallel to the rotation plane of the driving rod 53. The free end of the welding arm 63 is fixedly connected to a mounting plate 66. The mounting plate 66 is arranged parallel to the oil tank 91 and faces upward. Two welding guns 641 are respectively located at two ends of a heat dissipation tube 92 and are used for welding the connection between the two ends of the heat dissipation tube 92 and the oil tank 91 .

[0055] Reference Figure 3 and Figure 6 A solder ring 642 is fixedly connected to the bottom of the nozzle of the welding gun 641. The solder ring 642 is set as a half ring, and the inside of the solder ring 642 is hollow. The inside of the solder ring 642 is connected to the welding gun 641. The solder liquid heated in the welding gun 641 flows into the solder ring 642. The solder ring 642 abuts against the side wall of the end of the heat dissipation pipe 92. The solder ring 642 is provided with a plurality of guide grooves 643 on the side facing the heat dissipation pipe 92. The plurality of guide grooves 643 are arranged at equal intervals along the circumference of the solder ring 642. After the solder flows into the solder ring 642, it flows out through the guide groove 643 and flows to the connection between the heat dissipation pipe 92 and the oil tank 91, thereby completing the welding of the heat dissipation pipe 92. A welding gun driving motor 671 is fixedly connected to the top of the mounting plate 66. The transmission shaft of the welding gun driving motor 671 passes through the mounting plate 66 and is coaxially fixedly connected to a rotating rod 672. The center of a circle on one end surface of the heat dissipation tube 92 is located on the straight line where the axis of the rotating rod 672 is located. A connecting rod 673 is fixedly connected to the bottom of the rotating rod 672. The other end of the connecting rod 673 is fixedly connected to the center of the top of a welding gun 641.

The two transverse pulleys 674 are connected by a belt 675.

[0056] Reference Figure 3 and Figure 6, the welding gun driving motor 671 drives the rotating rod 672 connected thereto to rotate, and the rotating rod 672 drives the welding gun 641 to rotate around the axis of the rotating rod 672 through the connecting rod 673, thereby driving the solder ring 642 to rotate circumferentially along the end of the heat dissipation tube 92 to complete the welding of the end of the heat dissipation tube 92 for one circle; at the same time, the rotating rod 672 drives another rotating rod 672 to rotate through the belt 675, and the other rotating rod 672 drives another welding gun 641 to rotate along the axis of the rotating rod 672, thereby driving another solder ring 642 to rotate circumferentially along the other end of the heat dissipation tube 92 to complete the welding of the other end of the heat dissipation tube 92 for one circle. When the welding of both ends of a heat dissipation tube 92 is completed, the fourth lifting cylinder 62 drives the welding arm 63 to rise, and the first fixed component 1 or the second fixed component 2 slides along the feeding direction, so that the next heat dissipation tube 92 to be welded is located directly below a group of welding guns 641. At this time, the fourth lifting cylinder 62 drives the welding arm 63 to descend, and then welds the next heat dissipation tube 92.

[0057] Reference Figure 6 In order to improve welding efficiency, welding guns 641 can be set in multiple groups. Multiple groups of welding guns 641 are arranged along the length direction of the first guide rail 31. The number of welding guns 641 in each group is set to two, which are respectively set at the two ends of the same heat dissipation tube 92. Multiple groups of welding guns 641 can weld multiple heat dissipation tubes 92 at the same time. A longitudinal pulley 681 is coaxially fixedly connected to the transmission shaft of the welding gun driving motor 671. The rotating rod 672 at the top of the welding gun 641 close to the welding gun driving motor 671 in each group passes through the mounting plate 66 and is coaxially fixedly connected to the longitudinal pulley 681. The longitudinal pulley 681 on the welding gun driving motor 671 is connected to the longitudinal pulley 681 on the welding gun 641 through a belt 675, so that multiple groups of welding guns 641 are driven to rotate by one welding gun driving motor 671. In this embodiment, the welding guns 641 are set in two groups.

[0058] Reference Figure 1 , the loading robot 7 and the unloading robot 8 are both clamping robots, and the structure of the clamping robot is conventional technology, which will not be described in detail here. When the first fixed component 1 or the second fixed component 2 slides under the clamping claw of the loading robot 7, the loading robot 7 places the clamped oil tank 91 to be welded on the first fixed component 1 or the second fixed component 2. After the heat dissipation pipes 92 are welded around the oil tank 91, the first fixed component 1 or the second fixed component 2 drives the welded oil tank 91 to move under the unloading robot 8, and the unloading robot 8 clamps and removes the welded oil tank 91 from the first fixed component 1 or the second fixed component 2.

[0059] The implementation principle of a welding device for transformer production in an embodiment of the present application is as follows: before welding the heat dissipation pipe 92 on the oil tank 91, the first fixed component 1 first slides to the bottom of the loading robot 7, the loading robot 7 clamps the oil tank 91 and places it on the first fixed component 1, and makes the side of the oil tank 91 to be welded with the heat dissipation pipe 92 face upward, and two groups of clamps 13 clamp and fix the oil tank 91. At this time, the worker first inserts the heat dissipation pipe 92 on the upper side of the oil tank 91 into the hole on the oil tank 91, and then the first fixed component 1 transports the oil tank 91 to the bottom of the hammering component 5, the hammering component 5 automatically knocks the two ends of the heat dissipation pipe 92, so that the heat dissipation pipe 92 is tightly inserted into the hole on the oil tank 91, and then the first fixed component 1 transfers the oil tank 91 that has passed through the fixed heat dissipation pipe 92 to the bottom of the welding component 6, and the welding component 6 automatically welds the connection between the two ends of the heat dissipation pipe 92 and the oil tank 91.

[0060] After welding is completed, the first fixing component 1 drives the oil tank 91 to be transported to the bottom of the hammering component 5 again. During the transportation process, the two groups of clamps 13 drive the oil tank 91 to flip ninety degrees, so that the side of the oil tank 91 that needs to be welded with the heat dissipation tube 92 is facing upward. At this time, the previous operation is repeated, that is, the worker plugs in the heat dissipation tube 92 on this side, and then the hammering component 5 knocks the heat dissipation tube 92. After fixing, the first fixing component 1 transfers the oil tank 91 to the bottom of the welding component 6 for welding... and so on, until the heat dissipation tubes 92 are all welded around the oil tank 91. At this time, the first fixing component 1 transfers the welded oil tank 91 to the bottom of the unloading robot 8, and at the same time, the two groups of clamps 13 release the oil tank 91, and the unloading robot 8 clamps the welded oil tank 91 to the unloading position. At the same time, the first fixing component 1 slides to the bottom of the loading robot 7, and the loading robot 7 clamps the new oil tank 91 for loading, and the above operation is repeated.

[0061] At the same time, the second fixing component 2 also repeats this operation, and when the first fixing component 1 moves to the hammering component 5 to hammer the heat dissipation tube 92, the second fixing component 2 moves to the welding component 6 to weld the heat dissipation tube 92, thereby welding the two oil tanks 91 at the same time, improving the efficiency of welding the transformer heat dissipation tube 92.

[0062] During this process, workers only need to plug in the heat dissipation pipes 92 around the oil tank 91, and the hammering and fixing of the heat dissipation pipes 92 is completed by the hammering component 5, and the welding of the heat dissipation pipes 92 and the oil tank 91 is completed by the welding component 6. The first fixing component 1 transfers the oil tank 91, which greatly saves time, improves the efficiency of welding the heat dissipation pipes 92 of the transformer, and reduces the workload of workers.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
