Description

Technical Field

[0001] This invention relates to the field of welding technology, and more specifically, to a welding equipment for high-strength aluminum alloy automotive frames. Background Technology

[0002] With the rapid growth of the new energy vehicle market, the demand for lightweight materials has increased significantly. High-strength aluminum alloys, due to their excellent specific strength and corrosion resistance, have become a key material in automobile frame manufacturing. However, the high thermal conductivity, low ionization energy, and laser reflection properties of aluminum alloys result in poor stability during the welding process, leading to poor weld formation, large fluctuations in penetration depth, and high weld porosity. Therefore, surface treatment is essential for laser welding of aluminum alloys. The treated aluminum alloy parts must be welded within a specified time; otherwise, an oxide film easily forms on the surface, requiring secondary or even multiple treatments, leading to rework and waste. After welding, rapid cooling of the weld can easily cause cracks to form and propagate, directly affecting weld quality and structural strength, making it difficult to meet the demands of high-precision and high-efficiency production. Therefore, it is necessary to provide a high-strength aluminum alloy frame welding equipment for automobiles to address the problems mentioned in the background. Summary of the Invention

[0063] Please see Figures 1 to 7 In this embodiment of the invention, a high-strength aluminum alloy automotive frame welding equipment includes:

[0064] Conveying platform 1, for conveying car frames;

[0065] Fixed columns 2 are fixed on both sides of the conveyor platform 1;

[0066] The sliding adjustment plate 3 is slidably mounted on the fixed column 2;

[0067] Welding device 4 is rotatably mounted on sliding adjustment plate 3;

[0068] The control connection component 5 is rotatably mounted on the welding device 4;

[0069] The pretreatment device 6 is rotatably mounted on one side of the control connection assembly 5;

[0070] The cooling device 7 is rotatably mounted on the other side of the control connection assembly 5, which is symmetrical to the pretreatment device 6.

[0071] In this embodiment, the welding device 4 includes:

[0072] The outer frame 41 is rotatably mounted on the sliding adjustment plate 3;

[0073] The welding gun 42 is movable within the connecting frame 41.

[0074] In other words, the sliding adjustment plate 3 moves up and down on the fixed column 2 to adjust the height of the welding device 4, and the connecting frame 41 rotates on the sliding adjustment plate 3, driving the welding gun 42 to rotate, adjusting the angle of the welding gun 42, and the welding gun 42 moves in the connecting frame 41 so that the welding gun 42 can better fit the welding area for welding work.

[0075] In this embodiment, the control connection component 5 includes:

[0076] Rotate the frame 51, which is rotatably mounted on the connecting outer frame 41;

[0077] Two rotating rods 52 are symmetrically distributed and are rotatably mounted on both sides of the rotating frame 51;

[0078] Adjusting rod 53 is provided corresponding to rotating rod 52. One end is slidably connected to rotating rod 52, and the other end is rotatably connected to the corresponding pretreatment device 6 and cooling device 7 respectively.

[0079] In other words, according to the direction of the weld joint, the rotating frame 51 rotates, and the rotating rod 52 and adjusting rod 53 drive the pretreatment device 6 and the cooling device 7 to come into contact with the weld joint. The pretreatment device 6 cleans the oxide layer on the surface of the weld joint. After cleaning, the welding device 4 performs welding. After welding, the cooling device 7 controls the temperature of the weld to reduce crack generation and propagation, and improve welding quality and structural strength.

[0080] In this embodiment, the pretreatment device 6 includes:

[0081] The first adjusting and closing mechanism 61 is rotatably connected to the control connection assembly 5;

[0082] The first fixed rotating shaft 62 is fixedly installed inside the first adjusting and closing mechanism 61;

[0083] Cleaning component 63 is rotatably mounted on one side of the first fixed rotating shaft 62;

[0084] The dust removal component 64 is symmetrically arranged with the cleaning component 63 and is rotatably mounted on the first fixed rotating shaft 62.

[0085] In other words, under the action of the first adjusting and closing mechanism 61, the pretreatment device 6 is brought into contact with the welding joints at different angles. When cleaning and removing dust from the oxide layer on the surface of the welding joint, it remains in a closed state, effectively preventing the debris from splashing and making it difficult for the dust removal component 64 to completely remove it, thus affecting the welding quality. Furthermore, under the action of the first fixed rotating shaft 62, the cleaning component 63 and the dust removal component 64 are controlled to come into contact with the welding joint. When dealing with welding trajectories with curvature or angles, the cleaning component 63 and the dust removal component 64 are restricted from coming into contact with the welding joint for processing, making it more versatile and applicable to different welding joints.

[0086] In this embodiment, the cooling device 7 includes:

[0087] The second adjusting and closing mechanism 71 is rotatably connected to the control connection assembly 5 and has the same structure as the first adjusting and closing mechanism 61.

[0088] The second fixed rotating shaft 72 is fixedly installed inside the second adjusting and closing mechanism 71;

[0089] The atomizing cooling component 73 is rotatably mounted on one side of the second fixed rotating shaft 72;

[0090] The conductive cooling component 74 is symmetrically arranged with the atomizing cooling component 73 and is rotatably mounted on the second fixed rotating shaft 72.

[0091] In other words, under the action of the second adjusting and closing mechanism 71, the cooling device 7 is made to be completely in contact with the weld seam to be cooled at different angles. The atomizing cooling component 73 rapidly cools the weld seam and inhibits grain coarsening. Then, the conductive cooling component 74 conducts cooling to homogenize the structure and eliminate residual stress. Under the action of the second fixed rotating shaft 72, the angles of the atomizing cooling component 73 and the conductive cooling component 74 are adjusted in real time according to the trajectory of the welding joint, so that the atomizing cooling component 73 and the conductive cooling component 74 are in contact with the weld seam for cooling.

[0092] In this embodiment, the first adjusting and closing mechanism 61 includes:

[0093] The fixed arc surface 611 is rotatably connected to the control connection assembly 5 at its top center.

[0094] Rotate the arc surface 612. Two pieces are symmetrically distributed about the fixed arc surface 611 and are slidably disposed on the inner side of the fixed arc surface 611.

[0095] The fixed sector surface 613 is fixed at both ends of the fixed arc surface 611;

[0096] Rotate the sector surface 614, fix it at both ends of the rotating arc surface 612, and slide it inside the fixed sector surface 613;

[0097] Two sets of drive rollers 615 are symmetrically distributed and rotatably mounted on the inner wall of the fixed sector surface 613 and in contact with the inner wall of the rotating arc surface 612. The rotating sector surface 614 is provided with an arc track corresponding to the drive rollers 615.

[0098] The connecting shaft 616 rotatably connects two sets of corresponding drive rollers 615;

[0099] The telescopic shaft 617 is fixedly connected at both ends to the end of the first fixed rotating shaft 62 and the middle of the connecting shaft 616, respectively.

[0100] In other words, when the weld joint is a flat surface, the rotating arc surfaces 612 and rotating sector surfaces 614 on both sides fit against the flat surfaces on both sides of the weld joint to clean the weld joint or cool the weld. When the included angle at the weld joint is an acute angle, the drive roller 615 rotates, causing the rotating arc surfaces 612 on both sides of the fixed arc surface 611 to rotate towards the center, and simultaneously causing the rotating sector surfaces 614 to rotate towards the fixed sector surface 613, so that the sides of the rotating arc surfaces 612 and rotating sector surfaces 614 fit against the flat surfaces on both sides of the weld joint. At the same time, the telescopic shaft 617 retracts. The corresponding fixed shaft is moved upward to adapt to the included angle, ensuring that the cleaning and cooling work proceeds normally. When the included angle at the weld joint is an obtuse angle, the roller 615 is driven to rotate, which drives the rotating arc surfaces 612 on both sides of the fixed arc surface 611 to rotate outward, and at the same time drives the rotating sector surface 614 to rotate away from the fixed sector surface 613, so that the sides of the rotating arc surfaces 612 and the rotating sector surface 614 on both sides are in contact with the planes on both sides of the weld joint. At the same time, the telescopic shaft 617 drives the corresponding fixed rotating shaft to move and adjust according to the weld position to adapt to the included angle, ensuring that the cleaning and cooling work proceeds normally.

[0101] In this embodiment, the cleaning component 63 includes:

[0102] The first connecting frame 631 is rotatably connected to the side of the first fixed rotating shaft 62;

[0103] The cleaning brush group 632 has two sets symmetrically distributed about the middle of the first fixed rotating shaft 62, and is movably set at the bottom of the first connecting frame 631.

[0104] In other words, under the action of the first fixed rotating shaft 62, the first connecting frame 631 drives the cleaning brush group 632 to fit against the welding joint. As the cleaning brush group 632 moves back and forth in the first connecting frame 631, the oxide layer at the welding joint is removed. The cleaning brush group 632 can also be rotated to adjust the brush head angle, so that the cleaning brush group 632 can thoroughly clean the welding joint.

[0105] In this embodiment, the dust removal component 64 includes:

[0106] The second connecting frame 641 is rotatably connected to the side of the first fixed rotating shaft 62 away from the cleaning component 63;

[0107] The fixing rod 642 is arranged parallel to the first fixing shaft 62 and is rotatably set at the bottom of the second connecting frame 641;

[0108] Rotate the collection trough 643 and fix it on the fixing rod 642;

[0109] The extension groove 644 is slidably connected to the opening of the rotating collection groove 643.

[0110] In other words, under the action of the first fixed rotating shaft 62, the second connecting frame 641 drives the dust removal component 64 to fit against the welding joint. The second connecting frame 641 is equipped with a dust suction mechanism. By rotating the fixed rod 642, the rotating collection groove 643 is driven to fit against the welding joint. The dust suction mechanism collects and cleans the debris. Under the action of the extension groove 644, when the included angle at the welding joint is an acute angle, the extension groove 644 extends and fits against the welding joint, which better collects and processes the debris cleaned by the cleaning component 63, ensuring a clean welding environment.

[0111] In this embodiment, the atomizing cooling component 73 includes:

[0112] The third connecting frame 731 is rotatably connected to the side of the second fixed rotating shaft 72 adjacent to the pretreatment device 6;

[0113] Two rotating connecting plates 732 are symmetrically distributed about the middle of the second fixed rotating shaft 72 and are rotatably set inside the third connecting frame 731;

[0114] Two sets of spray nozzles 733 are symmetrically arranged with the rotating connecting plate 732, with multiple nozzles in each set arranged in a straight line and fixed on the rotating connecting plate 732.

[0115] In other words, under the action of the second fixed rotating shaft 72, the third connecting frame 731 drives the atomizing cooling component 73 to fit against the weld. Driven by the rotating connecting plate 732, the spray nozzle 733 rotates in the direction of the weld, spraying out atomized droplets to quickly cool the weld and suppress grain coarsening.

[0116] In this embodiment, the conductive cooling component 74 includes:

[0117] The fourth connecting frame 741 is rotatably connected to the side of the second fixed rotating shaft 72 away from the atomizing cooling assembly 73;

[0118] Multiple sliding cooling frames 742 are coaxially arranged and slide relative to each other;

[0119] Two limiting rings 743 are symmetrically distributed vertically and fixed to the inner sides of the upper and lower ends of the sliding cooling frame 742, respectively.

[0120] The positioning ring 744 is fixed to the top outer side of the sliding cooling frame 742, and the positioning ring 744 is located between the limiting rings 743.

[0121] Under the action of the second fixed rotating shaft 72, the fourth connecting frame 741 drives the conductive cooling component 74 to fit against the weld. Under the constraint of the included angle of the weld and the limitation of the limiting ring 743, the inner sliding cooling frame 742 slides on the outer sliding cooling frame 742 through the positioning ring 744, so that the sliding cooling frame 742 fits against the weld, conducts cooling on the weld, homogenizes the structure, eliminates residual stress, effectively reduces the generation and propagation of cracks at the weld, and improves the welding quality and structural strength.

[0122] In practice, the car frame is first carried and transported by the conveying platform 1. Positioning clamps on the platform surface ensure frame stability. The height of the welding device 4 is adjusted by the sliding adjustment plate 3 moving up and down on the fixed column 2. The connecting outer frame 41 rotates on the sliding adjustment plate 3, causing the welding gun 42 to rotate and its angle adjusted. The welding gun 42 moves within the connecting outer frame 41, allowing it to better fit the welding area for welding. Next, the rotating frame 51 rotates on the connecting outer frame 41, causing the pretreatment device 6 and cooling device 7 to adapt to the spatial orientation of the car frame welding joint. Then, the adjusting and closing mechanism is adjusted according to the angle at the welding joint. When the welding joint is planar, the rotating arc surfaces 612 and rotating sector surfaces 614 on both sides maintain their initial positions, and closure is achieved by locking the drive roller 615. When the angle between the two planes of the welding joint is acute, the drive roller 615... The rotating arc surface 612 rotates inward, and the telescopic shaft 617 retracts to adapt to the acute angle weld. When the angle between the two planes of the weld joint is obtuse, the driving roller 615 rotates in the opposite direction, causing the rotating arc surface 612 to unfold outward, and the telescopic shaft 617 to extend to adapt to the obtuse angle weld structure. Then, the first connecting frame 631 fits into the weld under the action of the first fixed rotating shaft 62. The cleaning brush group 632 rotates and moves laterally under the drive of the motor to remove the oxide layer at the weld joint. The second connecting frame 641 has a built-in dust collection mechanism. The rotating collection groove 643 fits into the weld, and the extension groove 644 automatically extends in the case of acute angle to completely collect debris. After cleaning and dust removal, the welding device 4 performs welding. After welding is completed, the cooling device 7 moves to the weld position, first starts the atomizing cooling component 73 for rapid cooling, and then starts the conductive cooling component 74 for uniform cooling, effectively reducing the generation and propagation of cracks at the weld and improving welding quality and structural strength.
