Description

Technical Field

[0001] The invention relates to the technical field of micro-welding devices, and in particular to a high-temperature alloy / titanium alloy dissimilar foil micro-welding device. Background Art

[0002] High-temperature alloys, titanium alloys and other dissimilar metal materials belong to different metal materials. Foil micro-welding is a welding technology that connects ultra-thin metal foils together. Foil micro-welding usually uses high-precision welding methods such as micro-beam plasma arc welding, laser welding, and electron beam welding. These methods can provide a high-energy density heat source, achieve precise welding control, and reduce welding deformation and heat-affected zone.

[0003] In the existing field of micro-welding technology for high-temperature alloy / titanium alloy dissimilar foils, traditional welding devices and methods have some limitations and shortcomings. First, these devices often neglect the necessary smoothing treatment of the foils during the welding process. For example, some metal foils are easily warped and slightly bulged due to external factors when placed. Direct welding of untreated foils will result in poor welding effect at the joints between the metal foils, affecting the welding quality. Manual processing of warped foils will not only increase the labor intensity of the staff, but may also further reduce the welding effect due to improper operation. Secondly, the existing welding devices have limitations in adjusting the welding position and are not easy to adapt and adjust to different shapes of welding points. This fixity limits the flexibility and application range of the welding device, making it difficult to achieve accurate and efficient welding operations for welding ports with variable shapes.

[0023] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] like Figure 1-4, a high-temperature alloy / titanium alloy dissimilar foil micro-welding device proposed in one embodiment of the present invention comprises: a base 1;

[0025] A support frame 2, the support frame 2 is fixedly installed on the top of the base 1, an electric push rod 3 is rotatably inserted on the support frame 2, a U-shaped plate 4 is fixedly installed on the telescopic end of the electric push rod 3, a moving block 5 is slidably installed on the top of the inner wall of the U-shaped plate 4, a welder 6 is fixedly installed on the bottom of the moving block 5, and a moving component 7 for driving the moving block 5 to move left and right is installed on the U-shaped plate 4;

[0026] A rotating assembly 8, wherein the rotating assembly 8 is mounted on the supporting frame 2 and is used to drive the electric push rod 3 to rotate;

[0027] There are four L-shaped plates 9, which are slidably mounted on the base 1. A connecting plate 10 is fixedly mounted between the bottoms of every two L-shaped plates 9. A lower pressing plate 11 is slidably mounted between every two L-shaped plates 9. A driving member 12 for driving the lower pressing plate 11 to move up and down is mounted on the L-shaped plate 9. A smoothing component 13 for smoothing the foil is mounted on the base 1.

[0028] The base 1 serves as the base of the entire device, providing the necessary stability and support. The support frame 2 is fixed on the top of the base 1, providing a solid platform for the installation and movement of the electric push rod 3. The electric push rod 3 drives the U-shaped plate 4 and the welder 6 thereon to move down to the welding position through telescopic movement. The cooperation between the U-shaped plate 4, the moving block 5 and the moving component 7 enables the welder 6 to flexibly align with different welding points, and can drive the welder 6 to move left and right along the length of the U-shaped plate 4. At the same time, in conjunction with the rotating component 8, the angle of the rotating U-shaped plate 4 can be adjusted to achieve all-round coverage of the welder 6 within a range of 360° to meet the welding requirements at different angles. This rotation mechanism enables the welder 6 to be easily adjusted to the optimal welding position.

[0029] There are four L-shaped plates 9, which are slidably installed on the base 1. The lower pressure plate 11 is slidably installed between the L-shaped plates 9. Its main function is to apply necessary pressure to the foil during welding to fix the position. The driving member 12 controls the up and down movement of the lower pressure plate 11. The pressure can be adjusted according to the thickness of the foil and the welding requirements to ensure close contact of the foil during welding.

[0030] The smoothing assembly 13 is installed on the base 1, and its function is to pre-treat the foil before welding, smooth the warping and unevenness of the foil surface to improve the welding effect. This step is crucial because it can eliminate the irregularities on the foil surface, reduce welding defects, and improve the strength and reliability of the welded joint. The two lower pressing plates 11 press down two different metal foils respectively.

[0031] During the welding process, firstly, the two foils to be welded are placed on the top of the base 1, and the smoothing component 13 pre-treats the foils to ensure that the foils are flat and have no warping. Subsequently, the electric push rod 3, driven by the rotating component 8, and the moving block 5, driven by the moving component 7, move the welder 6 to the predetermined welding position, and at the same time, the lower pressure plate 11 applies pressure to the foil under the action of the driving member 12 to keep the foil stable. By precisely controlling the movements of the electric push rod 3 and the lower pressure plate 11, the device can achieve precise positioning and stable welding of the foil, thereby improving welding quality, reducing manual intervention, and improving work efficiency. The entire welding process is automated, reducing human errors, while improving production efficiency and welding quality.

[0032] like Figure 1 As shown, in some embodiments, the moving component 7 includes a moving screw 71 rotatably installed between the two sides of the inner wall of the U-shaped plate 4, a driving motor 72 is fixedly installed on one side of the U-shaped plate 4, the output end of the driving motor 72 is fixedly connected to one end of the moving screw 71, and the moving screw 71 is threadedly connected to the moving block 5.

[0033] The driving motor 72 is started to drive the moving screw 71 to rotate forward and reverse, thereby driving the moving block 5 threadedly connected thereto to move left and right, and further driving the welding device 6 to move.

[0034] like Figure 1 As shown, in some embodiments, the rotating assembly 8 includes a rotating motor 81 fixedly mounted on the top of the support frame 2, a main gear 82 is fixedly mounted on the output end of the rotating motor 81, a slave gear 83 is fixedly sleeved on the electric push rod 3, and the main gear 82 is meshed with the slave gear 83.

[0035] The rotating motor 81 is started to drive the main gear 82 to rotate. Since the main gear 82 is meshed with the slave gear 83, the slave gear 83 can be driven to rotate, thereby driving the electric push rod 3 to rotate an angle.

[0036] like Figure 1 As shown, in some embodiments, the driving member 12 includes four first electric telescopic rods 121 respectively fixedly inserted on the four L-shaped plates 9 , and the telescopic ends of the first electric telescopic rods 121 are fixedly connected to the top of the lower pressure plate 11 .

[0037] The first electric telescopic rod 121 is started to drive the lower pressing plate 11 to press down, so as to press down the foil material, thereby facilitating the fixing of the foil material position and preventing the foil material from moving randomly during welding, thereby affecting the welding effect.

[0038] like Figure 4As shown, in some embodiments, a bidirectional threaded rod 14 is rotatably installed at the bottom of the base 1, and the two connecting plates 10 are threadedly connected to the bidirectional threaded rod 14, and a servo motor 16 is fixedly installed at the bottom of the base 1, and the output end of the servo motor 16 is fixedly connected to one end of the bidirectional threaded rod 14.

[0039] The servo motor 16 is started to drive the bidirectional threaded rod 14 to rotate, thereby driving the two connecting plates 10 to move closer to or away from each other, and at the same time driving the lower pressing plate 11 on the L-shaped plate 9 to move, so as to facilitate the downward pressing and fixing of foils of different sizes, and has a certain flexibility.

[0040] like Figure 1 and Figure 3 As shown, in some embodiments, the trowel assembly 13 includes two sliders 131 installed on one side of the base 1, a trowel plate 132 is slidably installed on the slider 131, and a second electric telescopic rod 133 for driving the trowel plate 132 to move up and down is fixedly installed on the slider 131. Two third electric telescopic rods 17 are fixedly installed on the top of the base 1, and the telescopic ends of the two third electric telescopic rods 17 are magnetically connected to the two sliders 131 respectively. A magnet is fixed to the telescopic end of the third electric telescopic rod 17, which is magnetically connected to the slider 131. The bottom of the trowel plate 132 is polished so as not to scratch the foil.

[0041] The second electric telescopic rod 133 is started to shrink its telescopic end, so that the trowel plate 132 on the slider 131 moves down to contact the surface of the foil. Then, the two third electric telescopic rods 17 are started to push the two sliders 131 closer to each other, and at the same time, the two trowel plates 132 are driven to move to smooth the surface of the foil.

[0042] like Figure 3 As shown, in some embodiments, a rotating rod 18 is rotatably mounted on one side of the base 1, an adjusting motor 19 is fixedly mounted on one side of the base 1, an output end of the adjusting motor 19 is fixedly connected to one end of the rotating rod 18, and the slider 131 is slidably connected to the rotating rod 18. A sliding groove is configured on the rotating rod 18, a limit block 20 is fixedly mounted on the slider 131, and the limit block 20 is slidably mounted in the sliding groove.

[0043] When the trowel plate 132 is not needed, it can be moved to another position, and the adjusting motor 19 can be started to drive the rotating rod 18 to rotate, thereby driving the slider 131 to rotate, and then driving the trowel plate 132 on it to rotate vertically to avoid affecting the welding of the welder 6, and when rotating, the slider 131 and the telescopic end of the third electric telescopic rod 17 can automatically separate the magnetic connection. The setting of the limit block 20 and the slide groove can make the slider 131 slide horizontally on the rotating rod 18, and the rotating rod 18 can drive the slider 131 to rotate when rotating.

[0044] like Figure 3 As shown, in some embodiments, protective rubber pads 21 are fixedly installed on the bottom of the two lower pressing plates 11 .

[0045] The protective rubber pad 21 can fix the pressed foil, increase the friction of the lower pressing plate 11, improve stability, and is not easy to cause wear to the foil.

[0046] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
