Description

Technical Field

[0001] This application relates to the technical field of water filtration treatment, and particularly relates to a high-strength aluminum alloy material and its welding device. Background Art

[0002] Aluminum alloy castings are widely used in many fields such as automotive manufacturing, aerospace, machinery manufacturing, and electronic communication due to their light weight, high strength, good corrosion resistance, and good thermal and electrical conductivity. In the automotive industry, aluminum alloy castings are used to manufacture engine components, wheels, etc. to reduce the body weight and improve fuel efficiency. In the aerospace field, they are used to manufacture structural components, casings, etc. to ensure the lightweight and high-strength requirements of aircraft. However, during the production or use of aluminum alloy castings, defects may sometimes occur or they need to be connected to other components. At this time, the defective parts need to be welded.

[0003] In the prior art, most often TIG welding is used to weld aluminum alloy castings to meet the requirements of connecting the defective parts or the positions connected to other components. When using TIG welding, an inert gas is ejected from the head of the welding torch for protecting the torch head, and most TIG welding is manually operated. After welding, the welded aluminum alloy castings are often moved to the inspection station by mechanical transmission to inspect the welding quality.

[0004] For the above related technologies, when the wall thickness of the aluminum alloy casting is large, simply welding the outer wall may not be sufficient to provide an effective connection effect. When the wall thickness of the aluminum alloy casting is large and the shape is relatively complex, it is very difficult for manual operation to weld the inner and outer walls of the aluminum alloy casting at the same time, and after welding, the aluminum alloy casting needs to be moved to the inspection station to be inspected, which is rather troublesome. Therefore, improvements are made. Summary of the Invention

[0005] In order to simultaneously weld the inner and outer walls of aluminum alloy castings with relatively complex shapes, and to improve the inspection efficiency of the welding effect of the welded aluminum alloy castings, this application provides a high-strength aluminum alloy material and its welding device.

[0006] The high-strength aluminum alloy material and its welding device provided by this application adopt the following technical solutions:

[0007] A high-strength aluminum alloy material and its welding device, including a mounting frame and an aluminum alloy casting. The aluminum alloy casting includes a spherical part and a cylindrical part. One end of the cylindrical part is arranged on the spherical part. Both the spherical part and the cylindrical part are hollow inside and are connected. A conveyor belt for transporting aluminum alloy materials is arranged on the mounting frame. A first hemispherical cover and a second hemispherical cover are respectively arranged on both sides of the conveyor belt. A first semi-cylindrical cover is arranged below the first hemispherical cover, and a second semi-cylindrical cover is arranged below the second hemispherical cover. A first driving component is arranged on the first semi-cylindrical cover and the second semi-cylindrical cover, which is used to drive the first hemispherical cover and the second hemispherical cover to cover the spherical part, and drive the first semi-cylindrical cover and the second semi-cylindrical cover to cover the cylindrical part;

[0008] A cylinder is arranged on the mounting frame, and the cylinder is arranged below the conveyor belt. A blocking plate is arranged on the telescopic end of the cylinder. The blocking plate is used to block one end of the cylindrical part away from the spherical part. The first hemispherical cover, the second hemispherical cover, the first semi-cylindrical cover, the second semi-cylindrical cover and the blocking plate enclose a welding station. The aluminum alloy casting is arranged on the welding station. An installation column is arranged on the surface of the blocking plate close to the spherical part. A first welding torch is rotatably arranged on the installation column. A second welding torch is arranged on the inner wall of the first hemispherical cover. A driving mechanism is arranged on the installation column and the blocking plate, which is used to drive the first welding torch to weld any position on the inner wall of the spherical part;

[0009] Inert gas outlets are arranged on both the first welding torch and the second welding torch for spraying inert gas to protect the gun head. And the inert gases used by the first welding torch and the second welding torch are different. And a connecting mechanism is arranged on the first welding torch and the second welding torch, which is used to make the second welding torch rotate around the rotation center of the first welding torch and keep the same rotation angular velocity as the first welding torch. A detection component is also arranged on the installation column for sealing detection of the welding effects of the first welding torch and the second welding torch.

[0010] By adopting the above technical solution, the aluminum alloy casting is conveyed between the first hemispherical cover and the second hemispherical cover through a conveyor belt. First, the air cylinder is started to make the plugging member abut against the bottom of the cylindrical portion of the aluminum alloy casting, so that the aluminum alloy component rises and separates from the conveyor belt. Then, under the action of the driving assembly, the first hemispherical cover and the second hemispherical cover are driven to wrap the spherical portion, so as to realize that the first hemispherical cover, the second hemispherical cover, the first half-cylindrical cover, the second half-cylindrical cover and the plugging plate enclose a welding station. The driving mechanism in the present application can drive the first welding torch to weld any position on the inner wall of the spherical portion. At the same time, under the action of the connecting mechanism, the first welding torch and the second welding torch maintain the same rotational angular velocity. Therefore, welding of any position on the outer wall of the spherical portion can also be realized, and synchronous welding of the first welding torch and the second welding torch can be realized. Compared with the traditional method of only welding the outer wall of the relatively thick aluminum alloy casting, the present application improves the welding quality and the welding efficiency at the same time; the detection component in the present application can also detect the welding effect of the aluminum alloy casting after welding is completed, so as to facilitate further processing of the aluminum alloy casting.

[0011] Optionally, the first driving assembly includes a first driving motor, a lead screw and a smooth rod. The first driving motor is arranged on the mounting frame. One end of the lead screw is connected to the output shaft of the first driving motor, and the other end is rotatably connected to the mounting frame. The smooth rod is rotatably arranged on the mounting frame. The lead screw is provided with a first thread section and a second thread section, and the first thread section and the second thread section are symmetrically arranged. The first half-cylindrical cover is threadedly connected to the first thread section, and the second half-cylindrical cover is threadedly connected to the second thread section. Moreover, the first half-cylindrical cover and the second half-cylindrical cover are slidably connected to the smooth rod. The first driving motor drives the lead screw to rotate, so that the first half-cylindrical cover and the second half-cylindrical cover approach or separate from each other.

[0012] By adopting the above technical solution, the first driving motor is started, and the first driving motor drives the lead screw to rotate. Since the lead screw is provided with a first thread section and a second thread section, and the first thread section and the second thread section are symmetrically arranged, the first half-cylindrical cover is threadedly connected to the first thread section, and the second half-cylindrical cover is threadedly connected to the second thread section. Therefore, the rotation of the lead screw can drive the first half-cylindrical cover and the second half-cylindrical cover to approach or separate from each other, so as to realize the wrapping of the spherical portion by the first hemispherical cover and the second hemispherical cover, and drive the first half-cylindrical cover and the second half-cylindrical cover to wrap the cylindrical portion, and then cooperate with the plugging plate to enclose a welding station, providing a basis for subsequent welding.

[0013] Optionally, the driving mechanism includes a second driving motor, a rotating column, a chain, a mounting rod, a driven gear, a driving gear, and a lateral driving assembly. The plugging plate partially protrudes from one end of the first half-column cover and the second half-column cover close to the cylinder. The second driving motor is disposed on the side wall of the plugging plate protruding from the first half-column cover and the second half-column cover. The driving gear is rotatably disposed in the plugging plate and connected to the output shaft of the second driving motor. The rotating column is rotatably disposed at one end of the mounting column away from the plugging plate. One end of the mounting rod is disposed in the middle of the rotating column. The first welding torch is disposed at one end of the mounting rod away from the rotating column. There are two groups of driven gears, and the two groups of driven gears are respectively disposed at both ends of the rotating column. The driven gears are connected to the driving gear through the chain. The lateral driving assembly is used to drive the mounting column to rotate. An avoidance groove is formed in the mounting column corresponding to the chain. A placement groove is formed in the mounting column. In the initial state, the mounting rod and the first welding torch are disposed in the placement groove.

[0014] By adopting the above technical solution, when the second driving motor is started, the second driving motor drives the driving gear to rotate. Since the driven gear is connected to the driving gear through the chain, the rotating rod connected to the driven gear can be driven to rotate. Since the first welding torch is mounted on the rotating column through the mounting rod, the rotation of the rotating rod can drive the first welding torch to rotate in the vertical direction. The lateral driving assembly in the present application can drive the first welding torch to rotate in the horizontal direction, so that the first welding torch can weld all positions on the inner wall of the spherical part.

[0015] Optionally, the lateral driving assembly includes a toothed disc, a driving gear, and a third driving motor. The toothed disc is rotatably disposed on the mounting frame. The fixed end of the cylinder is disposed on the toothed disc. The third driving motor is disposed on the mounting frame. The driving gear is disposed on the output shaft of the third driving motor. The driving gear meshes with the toothed disc.

[0016] By adopting the above technical solution, when the third driving motor is started, the third driving motor drives the driving gear to rotate. Since the driving gear meshes with the toothed disc, the third driving motor can drive the cylinder on the toothed disc to rotate. Since the plugging plate is disposed on the telescopic end of the cylinder and the mounting column is disposed on the plugging plate, the rotation of the mounting column is realized, so that the first welding torch can rotate in the horizontal direction.

[0017] Optionally, the connecting mechanism includes a first electromagnet, a second electromagnet, a first arc-shaped mounting plate, a second arc-shaped mounting plate and an adjusting component. The first arc-shaped mounting plate is arranged at the end of the mounting rod away from the rotating column and sleeved on the first welding torch. The first electromagnet is arranged on the first arc-shaped mounting plate. The second arc-shaped mounting plate is slidably arranged between the first hemispherical cover and the spherical part and sleeved on the second welding torch. The second electromagnet is arranged on the second arc-shaped mounting plate. When the first electromagnet and the second electromagnet are started, the first electromagnet and the second electromagnet attract each other. When the first electromagnet moves, the second electromagnet moves synchronously under the action of magnetic force. The adjusting component is arranged on the first arc-shaped mounting plate and the second arc-shaped mounting plate and is used to adjust the distance between the first welding torch and the second welding torch and the aluminum alloy casting before welding.

[0018] By adopting the above technical solution, when the first electromagnet and the second electromagnet are started, the first electromagnet and the second electromagnet attract each other, so that the second arc-shaped mounting plate is adsorbed on the outer wall of the spherical part through the first electromagnet and the second electromagnet. When the mounting rod drives the first arc-shaped mounting plate to move, the second arc-shaped mounting plate can move synchronously and maintain the same rotational angular velocity as the first arc-shaped mounting plate, so as to achieve the same rotational angular velocity between the first welding torch and the second welding torch, and the inner and outer walls of the spherical part can be welded simultaneously, improving the welding efficiency. The adjusting component can adjust the distance between the first welding torch and the second welding torch and the aluminum alloy casting, thus avoiding damage to the tips of the first welding torch and the second welding torch during welding.

[0019] Optionally, the adjusting component includes a first ball, a second ball, a magnet, an electric telescopic rod and a third ball. The first ball is arranged on the surface of the first arc-shaped mounting plate away from the mounting rod. The second ball is arranged on the surface of the second arc-shaped mounting plate close to the spherical part. The third ball is arranged on the surface of the second arc-shaped mounting plate away from the spherical part. The fixed end of the electric telescopic rod is arranged on the mounting rod. The first arc-shaped mounting plate is arranged on the telescopic end of the electric telescopic rod. Telescopic columns are arranged between the third ball and the second arc-shaped mounting plate and between the electric telescopic rod and the first arc-shaped mounting plate. Springs are sleeved on the telescopic columns. The magnet is embedded in the inner wall of the first hemispherical cover and is used to adsorb and fix the third ball after welding is completed.

[0020] By adopting the above technical solution, when the first arc-shaped mounting plate and the second arc-shaped mounting plate move, the first ball can reduce the friction between the first arc-shaped mounting plate and the inner wall of the spherical part, and the second ball can reduce the friction between the second arc-shaped mounting plate and the outer wall of the spherical part, which can better drive the first welding torch and the second welding torch, and can keep a certain distance between the tips of the first welding torch and the second welding torch and the aluminum alloy casting, improving the welding effect and avoiding damage to the tips. The electric telescopic rod can adjust the distance between the first welding torch and the mounting rod, so as to facilitate the abutment between the first ball and the inner wall of the spherical part. A telescopic column is arranged between the third ball and the second arc-shaped mounting plate, and a spring is sleeved on the telescopic column, which can make the third ball abut against the inner walls of the first hemispherical cover and the second hemispherical cover, thereby improving the stability of the second arc-shaped mounting plate. A telescopic column is arranged between the electric telescopic rod and the first arc-shaped mounting plate, and a spring is sleeved on the telescopic column, which can make the contact between the first ball and the inner wall of the spherical part become elastically released, and drive the first arc-shaped mounting plate more stably.

[0021] Optionally, the detection component includes a Tesla coil, a light sensor, a placement plate and an air pump. The Tesla coil is arranged in the placement groove and below the first welding torch. The placement plate is arranged in the placement groove and between the first welding torch and the Tesla coil. The light sensor is arranged on the side of the placement plate close to the Tesla coil. An air hole is opened at the bottom of the placement groove, and the air pump is arranged on the sealing plate for pumping air into the aluminum alloy casting through the air hole.

[0022] By adopting the above technical solution, the first welding torch and the second welding torch will spray different inert gases during welding to protect the tips. When welding is completed, the Tesla coil and the air pump are started. The Tesla coil can make the inert gas emit light, and the air pump can extract the gas inside the spherical part through the air hole at the bottom of the placement groove. If the welding is complete and under the action of the air pump, the gas inside the spherical part is extracted and in a vacuum state, the intensity of the light emitted by the Tesla coil to make the inert gas emit light will gradually weaken until there is no light and no discharge state. If there are still gaps in the welding of the aluminum alloy casting, because the inert gases used by the first welding torch and the second welding torch are inconsistent, and the Tesla coil can make different inert gases emit different colors of visible light, so during the process of the air pump pumping air into the spherical part, the color of the inert gas will change. At this time, whether the welding of the aluminum alloy casting is complete can be judged through the signal output of the light sensor.

[0023] Optionally, rubber layers are arranged on the mutually contacting surfaces of the first hemispherical cover, the second hemispherical cover, the first half-column cover and the second half-column cover.

[0024] By adopting the above technical solution, the rubber layer can improve the sealing effect between the contacting surfaces of the first hemispherical cover, the second hemispherical cover, the first semi-cylindrical cover and the second semi-cylindrical cover, thereby further improving the accuracy of the sealing detection after welding.

[0025] This application also includes a high-strength aluminum alloy material. By mass percentage, the aluminum alloy material includes the following components: 0.19% Si, 0.28% Fe, 0.055% Cu, 0.45% Mn, 4.28% Mg, 0.086% Cr, 0.027% Zn, 0.018% Ti, and the rest is Al.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The aluminum alloy casting is conveyed between the first hemispherical cover and the second hemispherical cover through a conveyor belt. First, start the cylinder to make the plugging member abut against the bottom of the cylindrical part of the aluminum alloy casting, so that the aluminum alloy part rises and separates from the conveyor belt. Then, under the action of the driving assembly, drive the first hemispherical cover and the second hemispherical cover to wrap the spherical part, thereby realizing that the first hemispherical cover, the second hemispherical cover, the first semi-cylindrical cover, the second semi-cylindrical cover and the plugging plate enclose a welding station. The driving mechanism in this application can drive the first welding torch to weld any position on the inner wall of the spherical part.

[0028] 2. Under the action of the connecting mechanism, the first welding torch and the second welding torch maintain the same rotational angular velocity. Therefore, it is also possible to weld any position on the outer wall of the spherical part, and realize the synchronous welding of the first welding torch and the second welding torch. Compared with the traditional method of only welding the outer wall, this application improves the welding quality and the welding efficiency at the same time.

[0029] 3. Different inert gases are sprayed by the first welding torch and the second welding torch during welding to protect the gun heads. When welding is completed, start the Tesla coil and the air pump. The Tesla coil can make the inert gas emit light, and the air pump can extract the gas inside the spherical part through the air holes at the bottom of the placement groove. If the welding is complete and under the action of the air pump, the gas inside the spherical part is extracted and in a vacuum state, the intensity of the light emitted by the inert gas by the Tesla coil will gradually weaken until there is no light and no discharge state. If there are still gaps in the welding of the aluminum alloy casting, because the inert gases used by the first welding torch and the second welding torch are different, and the Tesla coil can make different inert gases emit different colors of visible light, therefore, during the process of the air pump pumping the gas inside the spherical part, the color of the inert gas will change. At this time, the signal output of the photosensor can be used to judge whether the welding of the aluminum alloy casting is complete. Description of the Drawings

Detailed implementation manners

[0036] The following will further elaborate on the present application in conjunction with the attached Figures 1-4 drawings.

[0037] The embodiments of the present application disclose a high-strength aluminum alloy material and its welding device. Refer to Figure 1 and Figure 2, A high-strength aluminum alloy material and its welding device, including a mounting frame 1 and an aluminum alloy casting 2. The aluminum alloy casting 2 includes a spherical part 21 and a cylindrical part 22. One end of the cylindrical part 22 is arranged on the spherical part 21. Both the spherical part 21 and the cylindrical part 22 are hollow inside and are connected. A conveyor belt 3 for transporting aluminum alloy materials is arranged on the mounting frame 1. A first hemispherical cover 4 and a second hemispherical cover 5 are respectively arranged on both sides of the conveyor belt 3. A first half-cylindrical cover 41 is arranged below the first hemispherical cover 4, and a second half-cylindrical cover 51 is arranged below the second hemispherical cover 5. A first driving assembly 6 for driving the first hemispherical cover 4 and the second hemispherical cover 5 to cover the spherical part 21, and driving the first half-cylindrical cover 41 and the second half-cylindrical cover 51 to cover the cylindrical part 22 is arranged on the first half-cylindrical cover 41 and the second half-cylindrical cover 51. Rubber layers are arranged on the mutually contacting surfaces of the first hemispherical cover 4, the second hemispherical cover 5, the first half-cylindrical cover 41 and the second half-cylindrical cover 51.

[0038] A cylinder 11 is arranged on the mounting frame 1, and the cylinder 11 is arranged below the conveyor belt 3. A sealing plate 12 is arranged on the telescopic end of the cylinder 11. The sealing plate 12 is used to seal one end of the cylindrical part 22 away from the spherical part 21. The first hemispherical cover 4, the second hemispherical cover 5, the first half-cylindrical cover 41, the second half-cylindrical cover 51 and the sealing plate 12 enclose a welding station. The aluminum alloy casting 2 is arranged on the welding station. A mounting post 13 is arranged on the surface of the sealing plate 12 close to the spherical part 21. A first welding torch 14 is rotatably arranged on the mounting post 13. A second welding torch 15 is arranged on the inner wall of the first hemispherical cover 4. A driving mechanism 7 for driving the first welding torch 14 to weld any position on the inner wall of the spherical part 21 is arranged on the mounting post 13 and the sealing plate 12.

[0039] Inert gas outlets are arranged on both the first welding torch 14 and the second welding torch 15 for spraying inert gas to protect the gun heads. Moreover, the inert gases used by the first welding torch 14 and the second welding torch 15 are different. And a connecting mechanism 8 for making the second welding torch 15 rotate around the rotation center of the first welding torch 14 and keep the same rotational angular velocity as the first welding torch 14 is arranged on the first welding torch 14 and the second welding torch 15. A detection component 9 for hermetically detecting the welding effect of the first welding torch 14 and the second welding torch 15 is also arranged on the mounting post 13.

[0040] The aluminum alloy casting 2 is conveyed between the first hemispherical cover 4 and the second hemispherical cover 5 through the conveyor belt 3. First, the air cylinder 11 is started to make the plugging member abut against the bottom of the cylindrical portion 22 of the aluminum alloy casting 2, so that the aluminum alloy component rises and is separated from the conveyor belt 3. Then, under the action of the driving assembly, the first hemispherical cover 4 and the second hemispherical cover 5 are driven to wrap the spherical portion 21, so as to realize that the first hemispherical cover 4, the second hemispherical cover 5, the first half-column cover 41, the second half-column cover 51 and the plugging plate 12 enclose a welding station. The driving mechanism 7 in the present application can drive the first welding torch 14 to weld any position on the inner wall of the spherical portion 21. At the same time, under the action of the connecting mechanism 8, the first welding torch 14 and the second welding torch 15 maintain the same rotational angular velocity. Therefore, welding of any position on the outer wall of the spherical portion 21 can also be realized, and synchronous welding of the first welding torch 14 and the second welding torch 15 can be realized. Compared with the traditional method of only welding the outer wall, the present application improves the welding quality and the welding efficiency at the same time; the detection component 9 in the present application can also detect the welding effect of the aluminum alloy casting 2 after welding is completed, so as to facilitate further processing of the aluminum alloy casting 2. The rubber layer can improve the sealing effect between the surfaces where the first hemispherical cover 4, the second hemispherical cover 5, the first half-column cover 41 and the second half-column cover 51 are in contact with each other, so as to further improve the accuracy of the sealing detection after welding.

[0041] Referring to Figure 1 and Figure 2 , the first driving assembly 6 includes a first driving motor 61, a lead screw 62 and a smooth rod 63. The first driving motor 61 is arranged on the mounting frame 1. One end of the lead screw 62 is connected to the output shaft of the first driving motor 61, and the other end is rotatably connected to the mounting frame 1. The smooth rod 63 is rotatably arranged on the mounting frame 1. The lead screw 62 is provided with a first thread section and a second thread section, and the first thread section and the second thread section are symmetrically arranged. The first half-column cover 41 is threadedly connected to the first thread section, and the second half-column cover 51 is threadedly connected to the second thread section. Moreover, the first half-column cover 41 and the second half-column cover 51 are slidably connected to the smooth rod 63. The first driving motor 61 drives the lead screw 62 to rotate, so that the first half-column cover 41 and the second half-column cover 51 approach or move away from each other.

[0042] Start the first drive motor 61. The first drive motor 61 drives the lead screw 62 to rotate. Since the lead screw 62 is provided with a first thread section and a second thread section which are symmetrically arranged, the first half column cover 41 is threadedly connected to the first thread section, and the second half column cover 51 is threadedly connected to the second thread section. Therefore, the rotation of the lead screw 62 can drive the first half column cover 41 and the second half column cover 51 to approach or move away from each other, thereby realizing the covering of the spherical part 21 by the first hemispherical cover 4 and the second hemispherical cover 5, and driving the first half column cover 41 and the second half column cover 51 to cover the cylindrical part 22. Then, in cooperation with the sealing plate 12, a welding station is enclosed, providing a basis for subsequent welding.

[0043] Refer to Figure 3 and Figure 4 , the driving mechanism 7 includes a second drive motor 71, a rotating column 72, a chain 73, a mounting rod 74, a driven gear 75, a driving gear 76 and a lateral driving assembly 77. The sealing plate 12 partially extends out of one end of the first half column cover 41 and the second half column cover 51 close to the cylinder 11. The second drive motor 71 is arranged on the side wall of the sealing plate 12 extending out of the first half column cover 41 and the second half column cover 51. The driving gear 76 is rotatably arranged in the sealing plate 12 and is connected to the output shaft of the second drive motor 71. The rotating column 72 is rotatably arranged at one end of the mounting column 13 away from the sealing plate 12. One end of the mounting rod 74 is arranged in the middle of the rotating column 72. The first welding torch 14 is arranged at the end of the mounting rod 74 away from the rotating column 72. There are two groups of driven gears 75, and the two groups of driven gears 75 are respectively arranged at both ends of the rotating column 72. The driven gear 75 is connected to the driving gear 76 through the chain 73. The lateral driving assembly 77 is used to drive the mounting column 13 to rotate. An avoidance groove is provided on the mounting column 13 corresponding to the chain 73. A placement groove is provided on the mounting column 13. In the initial state, the mounting rod 74 and the first welding torch 14 are arranged in the placement groove.

[0044] Start the second drive motor 71. The second drive motor 71 drives the driving gear 76 to rotate. Since the driven gear 75 is connected to the driving gear 76 through the chain 73, the rotating rod connected to the driven gear 75 can be driven to rotate. Since the first welding torch 14 is installed on the rotating column 72 through the mounting rod 74, the rotation of the rotating rod can drive the first welding torch 14 to rotate in the vertical direction. The lateral driving assembly 77 in the present application can drive the first welding torch 14 to rotate in the horizontal direction, so that the first welding torch 14 can weld all positions on the inner wall of the spherical part 21.

[0045] Refer to Figure 1 and Figure 2, the lateral driving assembly 77 includes a toothed disc 771, a driving gear 772, and a third driving motor 773. The toothed disc 771 is rotatably arranged on the mounting bracket 1. The fixed end of the air cylinder 11 is arranged on the toothed disc 771. The third driving motor 773 is arranged on the mounting bracket 1. The driving gear 772 is arranged on the output shaft of the third driving motor 773. The driving gear 772 meshes with the toothed disc 771.

[0046] Start the third driving motor 773. The third driving motor 773 drives the driving gear 772 to rotate. Since the driving gear 772 meshes with the toothed disc 771, the third driving motor 773 can drive the air cylinder 11 on the toothed disc 771 to rotate. Since the plugging plate 12 is arranged on the telescopic end of the air cylinder 11 and the mounting post 13 is arranged on the plugging plate 12, the rotation of the mounting post 13 is realized, so that the first welding torch 14 can be rotated horizontally.

[0047] Refer to Figure 2 and Figure 3 , the connecting mechanism 8 includes a first electromagnet 81, a second electromagnet 82, a first arc-shaped mounting plate 83, a second arc-shaped mounting plate 84, and an adjusting assembly 85. The first arc-shaped mounting plate 83 is arranged at the end of the mounting rod 74 away from the rotating column 72 and sleeved on the first welding torch 14. The first electromagnet 81 is arranged on the first arc-shaped mounting plate 83. The second arc-shaped mounting plate 84 is slidably arranged between the first hemispherical cover 4 and the spherical part 21 and sleeved on the second welding torch 15. The second electromagnet 82 is arranged on the second arc-shaped mounting plate 84. Start the first electromagnet 81 and the second electromagnet 82. The first electromagnet 81 and the second electromagnet 82 attract each other. When the first electromagnet 81 moves, the second electromagnet 82 moves synchronously under the action of magnetic force. The adjusting assembly 85 is arranged on the first arc-shaped mounting plate 83 and the second arc-shaped mounting plate 84 and is used to adjust the distance between the first welding torch 14 and the second welding torch 15 and the aluminum alloy casting 2 before welding.

[0048] Start the first electromagnet 81 and the second electromagnet 82. The first electromagnet 81 and the second electromagnet 82 attract each other, so that the second arc-shaped mounting plate 84 is adsorbed on the outer wall of the spherical part 21 through the first electromagnet 81 and the second electromagnet 82. When the mounting rod 74 drives the first arc-shaped mounting plate 83 to move, the second arc-shaped mounting plate 84 can move synchronously and maintain the same rotational angular velocity as the first arc-shaped mounting plate 83, so as to realize the same rotational angular velocity between the first welding torch 14 and the second welding torch 15, and the inner and outer walls of the spherical part 21 can be welded simultaneously, improving the welding efficiency. The adjusting assembly 85 can adjust the distance between the first welding torch 14 and the second welding torch 15 and the aluminum alloy casting 2, so as to avoid damaging the tips of the first welding torch 14 and the second welding torch 15 during welding.

[0049] Referring to Figure 2 and Figure 3 Figure 3

[0050] When the first arc-shaped mounting plate 83 and the second arc-shaped mounting plate 84 move, the first ball 851 can reduce the friction between the first arc-shaped mounting plate 83 and the inner wall of the spherical portion 21, and the second ball 852 can reduce the friction between the second arc-shaped mounting plate 84 and the outer wall of the spherical portion 21, which can better drive the first welding torch 14 and the second welding torch 15, and can keep a certain distance between the tips of the first welding torch 14 and the second welding torch 15 and the aluminum alloy casting 2, improving the welding effect and avoiding damage to the tips. The electric telescopic rod 854 can adjust the distance between the first welding torch 14 and the mounting rod 74, so as to facilitate the abutment between the first ball 851 and the inner wall of the spherical portion 21. A telescopic column 856 is provided between the third ball 855 and the second arc-shaped mounting plate 84, and a spring 857 is sleeved on the telescopic column 856, which can make the third ball 855 abut against the inner walls of the first hemispherical cover 4 and the second hemispherical cover 5, thereby improving the stability of the second arc-shaped mounting plate 84. A telescopic column 856 is provided between the electric telescopic rod 854 and the first arc-shaped mounting plate 83, and a spring 857 is sleeved on the telescopic column 856, which can make the contact between the first ball 851 and the inner wall of the spherical portion 21 become elastically released, and drive the first arc-shaped mounting plate 83 more stably.

[0051] Referring to Figure 3 and Figure 4, the detection component 9 includes a Tesla coil 91, a photosensor 92, a placement plate 93 and an air pump 94. The Tesla coil 91 is arranged in the placement groove and below the first welding torch 14. The placement plate 93 is arranged in the placement groove and between the first welding torch 14 and the Tesla coil 91. The photosensor 92 is arranged on the side of the placement plate 93 close to the Tesla coil 91. Air holes are opened at the bottom of the placement groove. The air pump 94 is arranged on the sealing plate 12 and is used to pump air into the aluminum alloy casting 2 through the air holes.

[0052] When the first welding torch 14 and the second welding torch 15 are welding, different inert gases will be sprayed to protect the torch heads. When the welding is completed, the Tesla coil 91 and the air pump 94 are started. The Tesla coil 91 can make the inert gas emit light. The air pump 94 can extract the gas inside the spherical part 21 through the air holes at the bottom of the placement groove. If the welding is complete and under the action of the air pump 94, the gas in the spherical part 21 is extracted and in a vacuum state, the intensity of the light emitted by the inert gas by the Tesla coil 91 will gradually weaken until there is no light and no discharge state. If there are still gaps in the welding of the aluminum alloy casting 2, because the inert gases used by the first welding torch 14 and the second welding torch 15 are inconsistent, and the Tesla coil 91 can make different inert gases emit different colors of visible light. Therefore, during the process of the air pump 94 pumping air into the spherical part 21, the color of the inert gas will change. At this time, whether the welding of the aluminum alloy casting 2 is complete can be judged through the signal output of the photosensor 92.

[0053] The implementation principle of an aluminum alloy material with high strength and its welding device in the embodiment of the present application is as follows:

[0054] When the inner wall of the aluminum alloy casting 2 needs to be welded, first, the aluminum alloy casting 2 is conveyed between the first hemispherical cover 4 and the second hemispherical cover 5 through the conveyor belt 3. First, the air cylinder 11 is started to make the sealing part abut against the bottom of the cylindrical part 22 of the aluminum alloy casting 2, so that the aluminum alloy part rises and is separated from the conveyor belt 3. The first driving motor 61 is started, and the rotation of the lead screw 62 can drive the first half-column cover 41 and the second half-column cover 51 to approach each other, so that the first hemispherical cover 4 and the second hemispherical cover 5 cover the spherical part 21 to form a sealed space;

[0055] The second driving motor 71 is started, and the second driving motor 71 drives the driving gear 76 to rotate. The rotation of the rotating rod can drive the first welding torch 14 to rotate in the vertical direction. Then the third driving motor 773 is started, and the third driving motor 773 drives the driving gear 772 to rotate, realizing the rotation of the mounting column 13, and realizing the rotation of the first welding torch 14 in the horizontal direction, so that the first welding torch 14 can weld all positions on the inner wall of the spherical part 21;

[0056] When it is necessary to weld the outer wall of the aluminum alloy casting 2 simultaneously, the first electromagnet 81 and the second electromagnet 82 are activated. The first electromagnet 81 and the second electromagnet 82 attract each other, so that the second arc-shaped mounting plate 84 is adsorbed on the outer wall of the spherical portion 21 through the first electromagnet 81 and the second electromagnet 82. When the mounting rod 74 drives the first arc-shaped mounting plate 83 to move, the second arc-shaped mounting plate 84 can be moved synchronously and maintain the same rotational angular velocity as the first arc-shaped mounting plate 83, so as to achieve the same rotational angular velocity between the first welding torch 14 and the second welding torch 15, and the inner and outer walls of the spherical portion 21 can be welded simultaneously;

[0057] When it is necessary to detect the welding quality, the Tesla coil 91 and the air pump 94 are activated. The Tesla coil 91 can make the inert gas emit light, and the air pump 94 can extract the gas inside the spherical portion 21 through the air holes at the bottom of the placement groove. If the welding is complete and under the action of the air pump 94, the gas inside the spherical portion 21 is pumped out and in a vacuum state, the intensity of the inert gas emitting light by the Tesla coil 91 will gradually weaken until it is in a state of no light and no discharge. If there are still gaps in the welding of the aluminum alloy casting 2, because the inert gases used by the first welding torch 14 and the second welding torch 15 are inconsistent, and the Tesla coil 91 can make different inert gases emit different colors of visible light, so during the process of the air pump 94 pumping the gas inside the spherical portion 21, the color of the inert gas will change. At this time, whether the welding of the aluminum alloy casting 2 is complete can be judged through the signal output of the light sensor 92.
