Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and specifically to a welding device for door and window processing. Background Technology

[0002] Doors and windows are essential furniture items, and they can be categorized by material into thermally broken aluminum windows, PVC windows, aluminum-clad wood windows, and stainless steel windows. Among these, aluminum alloy windows are a common type of window in modern buildings, and their welding process is crucial to the product's quality and lifespan. The main welding methods for aluminum alloy windows include arc welding, friction stir welding, and laser welding. Argon arc welding is the most commonly used welding method, which can use DC or AC power and has the advantages of good weld quality and strong controllability.

[0003] Patent application CN118357624B discloses a door and window welding device, including a mounting frame. Multiple second electric rollers are mounted on both sides of the inner wall of the mounting frame, with circular holes pre-drilled between them. A mounting plate is rotatably connected to the inner wall of the mounting frame, located within the circular holes. Multiple third electric rollers are mounted on the inner wall of the mounting plate. Multiple first electric rollers are mounted at both ends of the inner wall of the mounting frame. A clamping assembly is mounted on the inner wall of the mounting plate. A driving assembly is mounted on the mounting frame and connected to the mounting plate. The device welds doors and windows using a mechanical welding arm on a third base. A first motor drives a first rotating shaft to rotate via a first synchronous pulley, which in turn drives the mounting plate to rotate, adjusting the welding angle of the doors and windows for welding.

[0004] The above describes conventional welding equipment used in door and window production. However, some smart doors and windows are equipped with smart door and window control boxes during production. These control boxes are usually embedded in grooves on the top or side of the door frame. In the actual production operation of welding door and window control boxes, firstly, a metal plate of appropriate thickness is selected as needed and its surface is treated. Then, the plate is partially cut according to the design drawings, i.e., the cutting depth is controlled to be less than the thickness of the plate, and the plate is bent at the cut position. The bent part is then welded using a welding device. Because the control box shell is formed by cutting and bending a single metal plate, the bent metal plate has a springback force. To maintain the bending angle after bending and prevent springback, the bent metal plate needs to be fixed during the welding process.

[0005] The welding device provided in the aforementioned patent document uses a moving block and a clamping block to limit and fix the sides of the door and window control box housing. In actual operation, the contact point between the moving block and the clamping block will obstruct the side edge of the door and window control box housing to be welded. It is necessary to change the position of the control box housing during the welding operation to achieve all-round welding of the control box housing. In addition, the contact position between the moving block and the clamping block and the sides of the control box housing is limited, which cannot fully overcome the springback force after the metal plate is bent. This can easily lead to local deformation and cracks at the welding position of the outer shell, affecting the welding quality of the door and window control box housing. Summary of the Invention

[0006] This invention provides a welding device for door and window processing, which aims to solve the problem in related technologies where welding devices cannot adequately fix the sides of the door and window control box shell during welding, resulting in local deformation and cracks due to the springback force of the metal sheet.

[0007] A welding device for door and window processing according to the present invention includes a welding base and a welding mechanism. The welding mechanism is used for welding a control box shell. The welding base is provided with a support plate, limiting components, and fixing components. There are two sets of limiting components, which are symmetrically arranged along the length direction of the support plate. The fixing components are located at one end of the length of the support plate and rotate relative to the welding base. With the end face of the control box shell opposite to the fixing components as the front end face, the two sets of limiting components are simultaneously opposite to the two sides, the top end face, and the rear end face of the control box shell. The device also includes a first driving component, a second driving component, and a third driving component. The first driving component drives the fixed component to slide along the length direction of the support plate. The second driving component simultaneously drives two sets of limiting components to slide longitudinally relative to the support plate. The third driving component is connected to any of the limiting components and drives the limiting component connected to it to move along the width direction of the support plate. The fixed component simultaneously abuts against the two sets of limiting components. The coverage area of ​​the limiting components and the fixed component relative to each end face of the control box is adapted to the size adjustment of the control box and avoids obstructing the side edges of the control box.

[0008] The beneficial effects are as follows: It reduces the local deformation and cracking caused by the springback force of the sheet metal during the welding operation of the door and window control box shell, improves the welding quality of the door and window control box shell, and fixes the control box shell to each end face by fixing the fixing components. Through the synergistic effect of the two sets of limiting components and fixing components, the side, top and rear ends of the door and window control box shell can be accurately positioned and fixed, effectively reducing the impact of springback force on the control box shell and ensuring the stability of the control box shell during the welding process. In addition, the drive components one, two and three are adapted to adjust the relative contact range between the limiting components and fixing components and each end face of the control box shell, which is suitable for fixing control box shells of different sizes. The limiting components and fixing components are in contact with each end face of the control box shell with a large coverage area, which further improves the stability of the control box shell during the welding process, reduces the stress at the weld during the welding process, and improves the flatness of the weld of the door and window control box shell.

Under the action of connecting part 2 and connecting part 3 abutting, fixing member 2 is driven to move synchronously with limiting member 2. The overall width of fixing member 2 and fixing member 1 is adapted to the width of the control box shell and automatically adjusted so as to fix the control box shell.

[0018] Preferably, each of the first limiting part and the second limiting part has a pressing block fixed to its lower side, and the pressing block is movably fitted to the upper surface of the control box housing.

[0019] The beneficial effects are as follows: when the first and second limiting parts move toward the upper end of the control box housing, they drive the pressing block to move closer to the control box housing until the pressing block abuts against the upper surface of the control box housing, thereby fixing the control box housing in this direction and improving the stability of the control box housing in the vertical direction.

[0040] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] like Figure 1 As shown, the welding apparatus for door and window processing of the present invention includes a welding base 1 and a welding mechanism. The welding mechanism is used to weld the control box shell 4 of the door and window control box. The welding mechanism includes a welding head 12 and a moving component 11. The moving component 11 is connected to the welding head 12 and is used to drive the welding head 12 to move so that the welding head 12 moves to different welding positions of the control box shell 4 for automatic welding. The structure and working method of the welding mechanism are prior art and will not be described in detail here. To ensure welding quality and reduce the problem of local deformation or cracks in the control box shell 4 caused by the rebound force during the welding process, the welding apparatus also includes a limiting component and a fixing component. The limiting component and the fixing component are attached to the end faces of the control box shell 4 to reduce the influence of the rebound force of the control box shell 4 and improve the stability and welding accuracy when welding the control box shell 4.

[0042] like Figures 2 to 5 As shown, a support plate 2 is fixed on the welding base 1. The support plate 2 can be a horizontally placed plate, and the control box shell 4 to be welded is placed on the support plate 2. There are two sets of limiting components, which are symmetrically arranged about the length of the support plate 2. The fixing component is located at one end of the length of the support plate 2 and can rotate relative to the welding base 1. When placing the control box shell 4 to be welded, the fixing component is rotated first, pushing the control box shell 4 from the end where the fixing component is located to the support plate 2. An adjusting component 3 is connected to the fixing component, and a driving component 35 is provided between the adjusting component 3 and the fixing component. The adjusting component 3 is connected to the fixing component through the driving component 35. The adjusting component 3 and the welding base 1 are rotatably engaged. The driving component 35 can be a cylinder. After the fixing component is adjusted to a vertical state with the adjusting component 3, the extension length of the piston rod of the driving component 35 can be controlled to push the fixing component to move along the length of the support plate 2. Here, the side opposite to the fixing component of the control box housing 4 is taken as the front side, and the side facing the front side of the control box housing 4 is taken as the front side. The drive component 35 is used to push the fixing component to fit with the front side of the control box housing 4. The two sets of limiting components are respectively used to fit with the two sides opposite to the control box housing 4, and the distance between the two sets of limiting components can be adjusted to match the width of the control box housing 4.

[0043] like Figure 2 , Figure 6 and Figure 7As shown, the limiting assembly includes a first limiting member 21 and a second limiting member 22. The first limiting member 21 is longitudinally slidably mounted on the support plate 2, and the second limiting member 22 is also longitudinally slidably fitted on the support plate 2. A second driving member, which can be a motor, is fixed to the lower end face of the support plate 2. The first limiting members 21 of both sets of limiting assemblies are fixed longitudinally relative to the protruding end of the second driving member, and one of the first limiting members 21 can slide relative to the second driving member along the width direction of the support plate 2. Specifically, a connecting plate 24 can be fixed to the protruding end of the second driving member. Both first limiting members 21 penetrate the support plate 2 and extend to the lower side of the support plate 2. One first limiting member 21 is fixed to the connecting plate 24, and the other first limiting member 21 slides along the width direction of the support plate 2 and simultaneously fits with both the support plate 2 and the connecting plate 24. The welding device also includes a third driving member 25. A mounting plate is fixed to one side of the support plate 2, and the third driving member 25 is mounted on the mounting plate. The driving component 3 25 can be a cylinder. The limiting component 1 21, which slides with the support plate 2, is fixed relative to the extended end of the driving component 3 25. By controlling the driving component 3 25, the two sets of limiting components can be pushed closer or further away to adapt to the width of different models of control box housing 4. The limiting component 2 22 slides with the limiting component 1 21 along the length direction of the support plate 2 and is elastically connected. The limiting component 1 21 and the limiting component 2 22 can be elastically connected by a spring. The limiting component 2 22 moves against the fixing component on the lower side of the support plate 2 so that after the driving component 35 pushes the fixing component to move backward to abut against the limiting component 2 22, it pushes the two limiting components 2 22 to move backward synchronously. The limiting component 2 22 slides relative to the limiting component 1 21 along the length direction of the support plate 2, so that the overall length of the limiting component 2 22 and the limiting component 1 21 can be adjusted to adapt to the length of the control box housing 4, while avoiding the limiting component 2 22 from obstructing the side edge of the control box housing 4 to be welded.

[0044] like Figure 6 and Figure 7As shown, during the welding of the control box housing 4, the two sets of limiting components simultaneously limit the upper and rear end faces of the control box housing 4. Limiting component 1 21 has an "L"-shaped limiting part 211, and limiting component 22 has an "L"-shaped limiting part 221. Both limiting part 1 211 and limiting part 221 are simultaneously opposite to the rear and upper end faces of the control box housing 4. Limiting part 221 slides along the length of the support plate 2 on the upper side of the control box housing 4, engaging with limiting part 1 211. Limiting part 1 211 and limiting part 221 can directly abut against the upper end face of the control box housing 4. The upper surface is fixed, or it can be fixed to the upper surface of the control box housing 4 by pressing the blocks 23. Each of the limiting parts 211 and 221 has a pressing block 23 fixed to its lower side. The pressing blocks 23 are located on the upper side of the control box housing 4 and are opposite to the upper surface of the control box housing 4. When the limiting part 21 moves downward, it drives the two pressing blocks 23 downward until they are in contact with the upper surface of the control box housing 4. The pressing blocks 23 are T-shaped, meaning they include a connecting part and an abutting part. The connecting part is perpendicular to the abutting part and is connected to either the limiting part 211 or the limiting part 221. The abutting part is horizontally positioned below the connecting part. When the limiting parts 211 and 221 move downward, they drive the pressing blocks 23 downward until the abutting part of the pressing blocks 23 abuts against the upper surface of the control box housing 4, thus fixing the control box housing 4 vertically.

[0045] The two limiting members 21 are also fixed with guide parts 212 opposite to the rear side of the control box housing 4. The two guide parts 212 slide and insert along the width direction of the support plate 2. The guide parts 212 are "L" shaped. The two guide parts 212 fit against the rear end face of the control box housing 4 to limit and fix the control box housing 4.

[0046] like Figure 4 and Figure 8As shown, the fixing assembly includes a first fixing member 31, a second fixing member 32, a first guide member 33, and a second guide member 34. The first fixing member 31 and the second fixing member 32 are slidably engaged along the width direction of the support plate 2. The first guide member 33 is slidably engaged with the first fixing member 31 longitudinally and is elastically connected. The first guide member 33 and the first fixing member 31 can be elastically connected by a spring. Specifically, a spring can be set between the first guide member 33 and the first fixing member 31. The spring is set along the sliding direction of the first fixing member 31 relative to the first guide member 33, and the two ends of the spring are respectively connected to the first fixing member 31 and the first guide member 33 to achieve the elastic connection between the two. Guide member 2 34 and fixing member 2 32 are longitudinally slidably engaged. Guide member 1 33 and guide member 2 34 are slidably engaged along the width direction of the support plate 2. Fixing member 1 31 and fixing member 2 32 are both slidably engaged with the support plate 2 along the length direction of the support plate 2. The lower end of fixing member 1 31 extends to the lower side of the support plate 2 and is fixed with connecting part 1 311. The lower end of fixing member 2 32 extends to the lower side of the support plate 2 and is fixed with connecting part 2 321. Connecting part 1 311 and connecting part 2 321 are respectively used to limit the movement of the two limiting members 2 22. Specifically, the front side of the limiting member 2 22 is fixed with a connecting part 321. Part 3 222, the connecting part 3 222 is located on the lower side of the support plate 2. The two connecting parts 3 222 are respectively opposite to the connecting part 1 311 and the connecting part 2 321. After the connecting part 1 311 and the connecting part 2 321 abut against the two limiting members 2 22, the two limiting members 2 22 are pushed to move backward synchronously along the length direction of the support plate 2. When the driving member 3 25 drives the two sets of limiting components to move closer to each other, the fixing member 1 31 and the fixing member 2 32 move closer synchronously with the movement of the two sets of limiting components. When the limiting members move down, the connecting part 3 222 drives the fixing member 1 31 and the fixing member 2 32 to move down synchronously.

[0047] like Figure 2 and Figure 4 As shown, the adjusting component 3 is located on the rear side of the fixed component. The adjusting component 3 is plate-shaped. The lower end of the adjusting component 3 is hinged to the welding base 1 through a hinge. The driving component 35 is installed on the adjusting component 3. The driving end of the driving component 35 is fixed to the guide component 33. When the control box 4 is pushed into or pulled out of the support plate 2, the driving component 35 is first driven to pull the fixed component closer to the adjusting component 3. Then the adjusting component 3 is rotated, and the fixed component rotates 90° with the adjusting component 3, so that the control box 4 can be picked up and put away.

[0048] The working process of the welding device provided by this invention is as follows:

[0049] Rotate the adjusting component 3 to make the fixing component rotate relative to the welding seat 1 to a horizontal state. The operator or other grabbing or moving equipment places the control box shell 4 to be welded on the support plate 2 from the end where the fixing component is located. Then rotate the adjusting component 3 to reset. The control box shell 4 is located in the space formed by the support plate 2, the fixing component and the two sets of limiting components. By adjusting the first driving component 35, the second driving component and the third driving component 25, the fixing component and the two sets of limiting components gradually adapt to the size of the control box shell 4 and fit together with each end face of the control box shell 4.

[0050] During the adjustment process, the first drive component 35 is activated first. The first drive component 35 pushes the fixing component to move along the direction close to the front end face of the control box housing 4. After the first connecting part 311 and the second connecting part 321 abut against the two third connecting parts 222 respectively, the two second limiting parts 22 move synchronously along the length direction of the support plate 2 with the fixing component. After the fixing component contacts the control box housing 4, it pushes the control box housing 4 to move to the rear. The control box housing 4 stops moving after it is in contact with the guide part 212. The control box housing 4 moves into place along the length direction of the support plate 2. During the movement of the fixing component, the second limiting part 22 slides relative to the first limiting part 21. The overall length of the first limiting part 21 and the second limiting part 22 automatically adjusts to the length of the control box housing 4 on both sides. At the same time, the second limiting part 221 slides relative to the first limiting part 211 along the length direction of the support plate 2. The overall length of the second limiting part 221 and the first limiting part 211 automatically adjusts to the length of the control box housing 4 on the upper end face of the control box housing 4.

[0051] Then, the drive component 3 25 is activated. The drive component 3 25 pushes a limiting component 1 21 to move along the width direction of the support plate 2. The limiting component 2 22 moves synchronously with the limiting component 1 21. Under the abutting action of the connecting part 2 321 and the connecting part 3 222, the fixing part 2 32 moves synchronously with the limiting component 2 22. The overall width of the fixing part 2 32 and the fixing part 1 31 is automatically adjusted to match the width of the control box 4. The limiting component 2 22, which slides with the extended end of the drive component 3 25, slides relative to the other limiting component 2 22 along the width direction of the support plate 2. The overall length of the two guide parts 212 is automatically adjusted to match the width of the control box 4 at the rear end face of the control box 4.

[0052] Then, drive component two is activated. Drive component two drives two limiting components 21 to move down synchronously through connecting plate 24. Limiting component two 22 moves down synchronously with limiting component one 21, and drives limiting part one 211 and limiting part two 221 to move down until pressing block 23 abuts against the upper surface of control box shell 4. The height of the limiting component and fixing component is automatically adjusted to the height of control box shell 4. This completes the limiting operation on each side of control box shell 4. At the same time, it avoids the limiting component and fixing component from obstructing the side edges of control box shell 4 to be welded. Finally, the welding mechanism is activated to weld each side edge of control box shell 4 in sequence, so as to fully limit control box shell 4 without affecting the welding operation of control box shell 4.

[0053] The welding device provided by the present invention simultaneously fixes each side of the control box shell 4 through a fixing component and two sets of limiting components. It is also convenient to automatically adjust the contact range with each side of the control box shell 4 according to the size of the control box shell 4, so that the fixing component and the limiting component maintain a large range of contact and fixation with the side of the control box shell 4, reducing the impact of local deformation and cracks caused by springback force at the welding position of the control box shell 4, and improving the welding quality of the control box shell 4.

[0054] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
