Description

Technical Field

[0001] The present application relates to the technical field of water filtration and treatment, and in particular to a high-strength aluminum alloy material and a welding device thereof. Background Art

[0002] Aluminum alloy castings are widely used in many fields such as automobile manufacturing, aerospace, machinery manufacturing, and electronic communications 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 parts, wheels, etc. to reduce the weight of the vehicle body and improve fuel efficiency. In the aerospace field, they are used to manufacture structural parts, shells, 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 need to be connected to other parts. At this time, the defective parts need to be welded.

[0003] In the prior art, TIG welding is mostly used to weld aluminum alloy castings to meet the requirements of connecting defective parts or positions connecting with other parts. When TIG welding is used, the welding torch head will spray inert gas to protect the torch head, and most TIG welding is done manually. After welding is completed, the welded aluminum alloy castings are often moved to an inspection station by mechanical transmission to inspect the welding quality.

[0004] Regarding the above-mentioned related technologies, when the wall thickness of the aluminum alloy casting is relatively large, welding only on the outer wall may not be sufficient to provide an effective connection effect. When the wall thickness of the aluminum alloy casting is relatively large and the shape is relatively complex, it is difficult to weld the inner and outer walls of the aluminum alloy casting at the same time by manual operation, and after welding, the aluminum alloy casting needs to be moved to the inspection station for inspection, which is relatively troublesome, so improvements are made.

The first welding gun and the second welding gun can be welded at the same position, and at the same time, under the action of the connecting mechanism, the first welding gun and the second welding gun maintain the same rotational angular velocity, so it is also possible to weld any position of the outer wall of the spherical part, and realize synchronous welding of the first welding gun and the second welding gun.

Since the driven gear is connected to the driving gear through a chain, the rotating rod connected to the driven gear can be driven to rotate. Since the first welding gun is installed on the rotating column through the mounting rod, the rotation of the rotating rod can drive the first welding gun to rotate in the vertical direction.

[0013] By adopting the above technical solution, the third drive motor is started, and the third drive motor drives the drive gear to rotate. Since the drive gear and the gear disc are meshed with each other, the third drive motor can drive the cylinder on the gear disc to rotate.

[0015] By adopting the above technical solution, the first electromagnet and the second electromagnet are started, and 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 by 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 be moved synchronously and maintain the same rotational angular velocity as the first arc-shaped mounting plate, thereby achieving the same rotational angular velocity between the first welding gun and the second welding gun, and the inner and outer walls of the spherical part can be welded at the same time, thereby improving the welding efficiency. The adjustment component can adjust the distance between the first welding gun and the second welding gun and the aluminum alloy casting, thereby avoiding damage to the gun heads of the first welding gun and the second welding gun during welding.

A telescopic column is arranged between the third ball and the second arc-shaped mounting plate, and a spring is arranged on the telescopic column, so that the third ball can 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 arranged on the telescopic column, so that the contact between the first ball and the inner wall of the spherical part can be elastically released, so as to drive the first arc-shaped mounting plate more stably.

If the welding of the aluminum alloy casting is incomplete and there are gaps, since the inert gases used by the first welding gun and the second welding gun are inconsistent, and the Tesla coil can make different inert gases emit visible light of different colors, the color of the inert gas will change during the process of the air pump exhausting the inside of the spherical part. At this time, the signal output of the photosensor can be used to determine whether the welding of the aluminum alloy casting is complete.

[0020] Optionally, a rubber layer is provided on the surfaces of the first hemispherical cover, the second hemispherical cover, the first semi-column cover and the second semi-column cover that contact each other.

[0024] 2. Under the action of the connecting mechanism, the first welding gun and the second welding gun maintain the same rotational angular velocity, so it is also possible to weld any position of the outer wall of the spherical part, and realize synchronous welding of the first welding gun and the second welding gun. Compared with the traditional method of only welding the outer wall, the present application improves the welding quality while also improving the welding efficiency.

[0025] 3. The first welding gun and the second welding gun will spray different inert gases to protect the gun heads during welding. When welding is completed, start the Tesla coil and the air pump. The Tesla coil can make the inert gas glow, and the air pump can extract the gas inside the spherical part through the air holes at the bottom of the placement groove.

One end of the screw rod 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 light rod 63 is rotatably arranged on the mounting frame 1. The screw rod 62 is provided with a first thread segment and a second thread segment. The first thread segment and the second thread segment are symmetrically arranged. The first semi-column cover 41 is threadedly connected to the first thread segment, and the second semi-column cover 51 is threadedly connected to the second thread segment.

[0034] Start the first drive motor 61, and the first drive motor 61 drives the screw rod 62 to rotate. Since the screw rod 62 is provided with a first thread segment and a second thread segment, the first thread segment and the second thread segment are symmetrically arranged, the first semi-column cover 41 is threadedly connected to the first thread segment, and the second semi-column cover 51 is threadedly connected to the second thread segment.

An avoidance groove is opened on the mounting column 13 corresponding to the chain 73, and a placement groove is opened on the mounting column 13. In the initial state, the mounting rod 74 and the first welding gun 14 are arranged in the placement groove.

[0036] The second drive motor 71 is started, and 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 gun 14 is installed on the rotating column 72 through the mounting rod 74, the rotation of the rotating rod can drive the first welding gun 14 to rotate in the vertical direction.

The driving gear 772 and the toothed disc 771 are meshed with each other.

[0038] The third drive motor 773 is started and drives the drive gear 772 to rotate. Since the drive gear 772 and the toothed disc 771 are meshed with each other, the third drive motor 773 can drive the cylinder 11 on the toothed disc 771 to rotate. Since the blocking plate 12 is arranged on the telescopic end of the cylinder 11 and the mounting column 13 is arranged on the blocking plate 12, the rotation of the mounting column 13 is realized, so the first welding gun 14 can be rotated in the horizontal direction.

The first electromagnet 81 and the second electromagnet 82 are started, and 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 component 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 gun 14 and the second welding gun 15 and the aluminum alloy casting 2 before welding.

[0040] The first electromagnet 81 and the second electromagnet 82 are started, and 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 gun 14 and the second welding gun 15, and the inner and outer walls of the spherical portion 21 can be welded at the same time, thereby improving the welding efficiency. The adjustment component 85 can adjust the distance between the first welding gun 14 and the second welding gun 15 and the aluminum alloy casting 2, so as to avoid damage to the gun heads of the first welding gun 14 and the second welding gun 15 during welding.

[0041] Reference Figure 2 and Figure 3 The adjustment component 85 includes a first ball 851, a second ball 852, a magnet 853, an electric telescopic rod 854 and a third ball 855. The first ball 851 is arranged on a surface of the first arc-shaped mounting plate 83 away from the mounting rod 74, the second ball 852 is arranged on a surface of the second arc-shaped mounting plate 84 close to the spherical portion 21, and the third ball 855 is arranged on a surface of the second arc-shaped mounting plate 84 away from the spherical portion 21. The fixed end of the electric telescopic rod 854 is arranged on the mounting rod 74, and the first arc-shaped mounting plate 83 is arranged on the telescopic end of the electric telescopic rod 854. A telescopic column 856 is arranged between the third ball 855 and the second arc-shaped mounting plate 84 and between the electric telescopic rod 854 and the first arc-shaped mounting plate 83. A spring 857 is sleeved on the telescopic column 856. The magnet 853 is embedded in the inner wall of the first hemispherical cover 4, which is used to adsorb and fix the third ball 855 after welding is completed.

[0042] When the first arc-shaped mounting plate 83 and the second arc-shaped mounting plate 84 are moving, 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, so that the first welding gun 14 and the second welding gun 15 can be driven better, and a certain distance can be maintained between the gun tips of the first welding gun 14 and the second welding gun 15 and the aluminum alloy casting 2, thereby improving the welding effect and avoiding damage to the gun tips. The electric telescopic rod 854 can adjust the distance between the first welding gun 14 and the mounting rod 74, so as to facilitate the first welding gun 14 and the second welding gun 15 to be driven better. A ball 851 is in contact with the inner wall of the spherical portion 21, and a telescopic column 856 is provided between the third ball 855 and the second arc-shaped mounting plate 84. 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 elastic and release, so as to drive the first arc-shaped mounting plate 83 more stably.

[0043] Reference Figure 3 and Figure 4 The detection component 9 includes a Tesla coil 91, a photo sensor 92, a placement plate 93 and an air pump 94. The Tesla coil 91 is arranged in the placement groove and is arranged below the first welding gun 14. The placement plate 93 is arranged in the placement groove and is located between the first welding gun 14 and the Tesla coil 91. The photo sensor 92 is arranged on a side of the placement plate 93 close to the Tesla coil 91. An air hole is opened at the bottom of the placement groove. The air pump 94 is arranged on the sealing plate 12 and is used to evacuate the inside of the aluminum alloy casting 2 through the air hole.

[0044] The first welding gun 14 and the second welding gun 15 will spray different inert gases to protect the gun heads during welding. When welding is completed, the Tesla coil 91 and the air pump 94 are started. The Tesla coil 91 can make the inert gas glow, and 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 is in a vacuum state, the intensity of the inert gas glow caused by the Tesla coil 91 will gradually weaken until there is no light and no discharge. If the welding of the aluminum alloy casting 2 is incomplete and there are gaps, since the inert gases used by the first welding gun 14 and the second welding gun 15 are inconsistent, and the Tesla coil 91 can make different inert gases emit visible light of different colors, the color of the inert gas will change during the process of the air pump 94 exhausting the inside of the spherical part 21. At this time, the signal output of the photosensitive device 92 can be used to determine whether the welding of the aluminum alloy casting 2 is complete.

[0045] The implementation principle of a high-strength aluminum alloy material and a welding device thereof in the embodiment of the present application is as follows: When the inner wall of the aluminum alloy casting 2 needs to be welded, the aluminum alloy casting 2 is first conveyed to between the first hemispherical cover 4 and the second hemispherical cover 5 by the conveyor belt 3, the cylinder 11 is first started to make the blocking piece abut against the bottom of the cylindrical portion 22 of the aluminum alloy casting 2 so that the aluminum alloy component rises and separates from the conveyor belt 3, and the first driving motor 61 is started. The rotation of the screw rod 62 can drive the first semi-column cover 41 and the second semi-column cover 51 to approach each other, so that the first hemispherical cover 4 and the second hemispherical cover 5 cover the spherical portion 21 to form a closed space; The second drive motor 71 is started, and the second drive motor 71 drives the driving gear 76 to rotate. The rotation of the rotating rod can drive the first welding gun 14 to rotate in the vertical direction. Then the third drive motor 773 is started, and the third drive motor 773 drives the driving gear 772 to rotate, so as to realize the rotation of the mounting column 13 and the rotation of the first welding gun 14 in the horizontal direction, so that the first welding gun 14 can weld all positions on the inner wall of the spherical portion 21; When it is necessary to weld the outer wall of the aluminum alloy casting 2 at the same time, the first electromagnet 81 and the second electromagnet 82 are started, and 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 by 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 maintained at 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 gun 14 and the second welding gun 15, and the inner and outer walls of the spherical part 21 can be welded at the same time; When it is necessary to detect the welding quality, start the Tesla coil 91 and the air pump 94. The Tesla coil 91 can make the inert gas emit light, and 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 is in a vacuum state, the intensity of the light emitted by the Tesla coil 91 will gradually weaken until there is no light and no discharge. If the welding of the aluminum alloy casting 2 is incomplete and there are gaps, since the inert gases used by the first welding gun 14 and the second welding gun 15 are inconsistent, and the Tesla coil 91 can make different inert gases emit visible light of different colors, the color of the inert gas will change during the process of the air pump 94 evacuating the inside of the spherical part 21. At this time, the signal output of the photosensor 92 can be used to determine whether the welding of the aluminum alloy casting 2 is complete.
