Description

Technical Field

[0001] This invention relates to the field of micro-welding device technology, specifically to a micro-welding device for high-temperature alloy / titanium alloy dissimilar foil materials. Background Technology

[0002] High-temperature alloys and dissimilar titanium alloys are 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 field of existing high-temperature alloy / titanium alloy dissimilar foil micro-welding technology, traditional welding devices and methods have some limitations and shortcomings. First, these devices often neglect the necessary smoothing treatment of the foil during the welding process. For example, some metal foils are prone to warping or bulging due to external factors when placed. Welding untreated foils directly will result in poor welding effect at the joint between metal foils, affecting the welding quality. Manually handling the warped foils not only increases the labor intensity of workers, but may also further reduce the welding effect due to improper operation. Second, existing welding devices have limitations in adjusting the welding position and are not easy to adapt and adjust to different welding joint shapes. This fixedness limits the flexibility and application range of the welding device, making it difficult to achieve precise and efficient welding operations for weld joints with varying shapes. Summary of the Invention

[0004] The purpose of this invention is to provide a micro-welding device for dissimilar high-temperature alloy / titanium alloy foils to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution: a micro-welding device for dissimilar high-temperature alloy / titanium alloy foils, comprising: a base; a support frame, the support frame being fixedly installed on the top of the base, an electric push rod being rotatably inserted on the support frame, a U-shaped plate being fixedly installed on the telescopic end of the electric push rod, a moving block being slidably installed on the top of the inner wall of the U-shaped plate, a welder being fixedly installed on the bottom of the moving block, and a moving component for driving the moving block to move left and right being installed on the U-shaped plate; a rotating component, the rotating component being installed on the support frame, for driving the electric push rod to rotate; four L-shaped plates, the four L-shaped plates being slidably installed on the base, a connecting plate being fixedly installed between the bottoms of every two L-shaped plates, a lower pressure plate being slidably installed between every two L-shaped plates, a driving component for driving the lower pressure plate to move up and down being installed on the L-shaped plates, and a smoothing component for smoothing the foil being installed on the base.

[0007] Furthermore, the rotating assembly includes a rotating motor fixedly installed on the top of the support frame, a main gear fixedly installed at the output end of the rotating motor, and a driven gear fixedly sleeved on the electric push rod, with the main gear meshing with the driven gear.

[0008] Furthermore, the driving component includes four first electric telescopic rods that are respectively fixedly inserted into the four L-shaped plates, and the telescopic ends of the first electric telescopic rods are fixedly connected to the top of the lower pressure plate.

[0009] Furthermore, a bidirectional threaded rod is rotatably mounted on the bottom of the base, and both connecting plates are threadedly connected to the bidirectional threaded rod. A servo motor is fixedly mounted on the bottom of the base, and the output end of the servo motor is fixedly connected to one end of the bidirectional threaded rod.

[0010] Furthermore, the smoothing assembly includes two sliders mounted on one side of the base, a smoothing plate slidably mounted on the sliders, and a second electric telescopic rod fixedly mounted on the sliders for driving the smoothing plate to move up and down.

[0011] Furthermore, two third electric telescopic rods are fixedly installed on the top of the base, and the telescopic ends of the two third electric telescopic rods are magnetically connected to the two sliders respectively.

[0012] Furthermore, a rotating rod is rotatably mounted on one side of the base, and an adjusting motor is fixedly mounted on one side of the base. The output end of the adjusting motor is fixedly connected to one end of the rotating rod, and the slider is slidably connected to the rotating rod.

[0013] Furthermore, the rotating rod is provided with a groove, and a limiting block is fixedly installed on the slider, with the limiting block slidably installed within the groove.

[0016] 1. This invention enables the welder to flexibly align with different welding points through the cooperation between the U-shaped plate, the moving block, and the moving component.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figure 1As shown in Figure 4, a high-temperature alloy / titanium alloy dissimilar foil micro-welding device according to an embodiment of the present invention includes: a base 1;

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

[0026] Rotating assembly 8, which is mounted on the support frame 2, 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 installed between the bottoms of every two L-shaped plates 9. A lower pressure plate 11 is slidably mounted between every two L-shaped plates 9. A driving component 12 for moving the lower pressure plate 11 up and down is installed on the L-shaped plates 9. A smoothing component 13 for smoothing foil is installed on the base 1.

[0028] The base 1 serves as the foundation of the entire device, providing necessary stability and support. The support frame 2 is fixed to 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, through telescopic movement, drives the U-shaped plate 4 and the welder 6 on it to move down to the welding position. The cooperation between the U-shaped plate 4, the moving block 5, and the moving component 7 allows the welder 6 to flexibly align with different welding points and can move the welder 6 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 360° range to adapt to welding requirements at different angles. This rotation mechanism allows the welder 6 to be easily adjusted to the optimal welding position.

[0029] There are four L-shaped plates 9, which are slidably mounted on the base 1. The lower pressure plate 11 is slidably mounted between the L-shaped plates 9. Its main function is to apply necessary pressure to the foil during the welding process and fix its position. The driving component 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 the welding process.

[0030] The smoothing component 13 is mounted on the base 1. Its function is to pre-treat the foil before welding, smoothing out any warped edges and unevenness on the foil surface to improve the welding effect. This step is crucial because it eliminates irregularities on the foil surface, reduces welding defects, and improves the strength and reliability of the weld joint. Two pressure plates 11 press down on two different metal foils respectively.

[0031] During the welding process, the two foils to be welded are first placed on top of the base 1. The smoothing component 13 pre-treats the foils to ensure they are flat and free of warped edges. Then, driven by the rotating component 8, the electric push rod 3 and the moving block 5, driven by the moving component 7, move the welder 6 to the predetermined welding position. Simultaneously, the lower pressure plate 11 applies pressure to the foils under the action of the driving component 12, maintaining foil stability. 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 foils, thereby improving welding quality, reducing manual intervention, and increasing work efficiency. The entire welding process is automated, reducing human error 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 mounted between the two sides of the inner wall of the U-shaped plate 4, a drive motor 72 is fixedly mounted on one side of the U-shaped plate 4, the output end of the drive 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 drive motor 72 is started to drive the moving screw 71 to rotate in both directions, which in turn drives the moving block 5, which is threadedly connected to it, to move left and right, and in turn drives the welder 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 fixedly mounted on the output end of the rotating motor 81, and a driven gear 83 fixedly sleeved on the electric push rod 3, with the main gear 82 meshing with the driven gear 83.

[0035] The start-up motor 81 drives the main gear 82 to rotate. Since the main gear 82 meshes with the driven gear 83, it can drive the driven gear 83 to rotate, which in turn drives the electric push rod 3 to rotate by an angle.

[0036] like Figure 1 As shown, in some embodiments, the driving component 12 includes four first electric telescopic rods 121 that are respectively fixedly inserted into 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 activated to drive the lower pressure plate 11 to press down, thereby pressing down the foil material to fix its position and prevent it from moving randomly during welding, which would affect the welding effect.

[0038] like Figure 4As shown, in some embodiments, a bidirectional threaded rod 14 is rotatably mounted on the bottom of the base 1, and both connecting plates 10 are threadedly connected to the bidirectional threaded rod 14. A servo motor 16 is fixedly mounted on 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, which can drive the two connecting plates 10 to move closer or further apart, and at the same time drive the lower pressure plate 11 on the L-shaped plate 9 to move, so as to press down and fix foils of different sizes, which has a certain degree of flexibility.

[0040] like Figure 1 and Figure 3 As shown, in some embodiments, the smoothing assembly 13 includes two sliders 131 mounted on one side of the base 1. A smoothing plate 132 is slidably mounted on the sliders 131, and a second electric telescopic rod 133 for moving the smoothing plate 132 up and down is fixedly mounted on the sliders 131. Two third electric telescopic rods 17 are fixedly mounted 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 and magnetically connected to the slider 131. The bottom of the smoothing plate 132 is polished to prevent scratching the foil.

[0041] Activating the second electric telescopic rod 133 causes its telescopic end to retract, which allows the smearing plate 132 on the slider 131 to move down and contact the foil surface. Then, activating the two third electric telescopic rods 17 pushes the two sliders 131 closer to each other, which in turn moves the two smearing plates 132 to smooth the foil surface.

[0042] like Figure 3 As shown, in some embodiments, a rotating rod 18 is rotatably mounted on one side of the base 1, and an adjusting motor 19 is fixedly mounted on one side of the base 1. The 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 groove is constructed on the rotating rod 18, and a limiting block 20 is fixedly mounted on the slider 131, with the limiting block 20 slidably mounted within the groove.

[0043] When the squeegee 132 is not needed, it can be moved to another position. Starting the adjusting motor 19 drives the rotating rod 18 to rotate, which in turn drives the slider 131 to rotate, thereby causing the squeegee 132 on it to rotate vertically, avoiding interference with the welding of the welder 6. During rotation, the slider 131 and the telescopic end of the third electric telescopic rod 17 can automatically separate and magnetically connect. The limiting block 20 and the sliding groove allow the slider 131 to slide laterally on the rotating rod 18, and also allow the rotating rod 18 to drive the slider 131 to rotate when it rotates.

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

[0045] The protective rubber pad 21 can fix the pressed foil material, increase the friction of the pressure plate 11, and improve stability. It also makes it less likely to cause wear to the foil material.

Various modifications to these embodiments will be readily apparent to those 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 invention.
