Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and in particular to a welding device for processing doors and windows. Background Art

[0002] Doors and windows are essential furniture components. They can be categorized by material, including thermally insulated aluminum, plastic-steel, aluminum-clad wood, and stainless steel. Aluminum alloy doors and windows are a common type of window in modern architecture, and their welding process is crucial to their quality and service life. The main welding methods for aluminum alloy doors and windows include arc welding, friction stir welding, and laser welding. Argon arc welding is the most commonly used method, operating with either DC or AC power sources. It offers advantages such as high weld quality and controllability.

[0003] Patent application document No. CN118357624B discloses a door and window welding device, comprising a mounting frame, with multiple second electric rollers mounted on either side of the inner wall of the mounting frame, with circular holes reserved between the multiple second electric rollers. A mounting plate is rotatably connected to the inner wall of the mounting frame, the mounting plate being located within the circular holes, multiple third electric rollers mounted on the inner wall of the mounting plate, multiple first electric rollers mounted on either end of the inner wall of the mounting frame, a clamping assembly mounted on the inner wall of the mounting plate, and a drive assembly mounted on the mounting frame, the drive assembly being connected to the mounting plate. Doors and windows are welded using a mechanical welding arm on a third machine base. A first motor drives a first rotating shaft to rotate via a first synchronous wheel, which in turn drives the mounting plate to rotate via the first rotating shaft, thereby adjusting the welding angle of the doors and windows for welding.

[0004] The above is a conventional welding device for door and window production. However, for some smart doors and windows, they are equipped with a smart door and window control box during production. The control box is usually embedded in a groove at the top or side of the door frame. In the actual production operation of welding door and window control boxes, first, a metal plate of appropriate thickness is selected according to the needs and its surface is processed. Then, the plate is partially cut according to the design drawings, that is, the cutting depth is controlled to be less than the thickness of the plate, and it is bent at the cutting position. The bent part is then welded using a welding device. Because the control box shell is formed by cutting and bending a whole metal plate, the bent metal plate has rebound force. In order to maintain the bending angle of the metal plate after bending and prevent it from rebounding, the bent metal plate needs to be fixed during the welding process. The moving block and the clamping block of the welding device provided in the above patent document limit and fix the side surfaces of the shell of the door and window control box. During actual operation, the joint between the moving block and the clamping block will block the side edges of the shell of the door and window control box to be welded. It is necessary to change the position of the control box shell during the welding operation to achieve all-round welding of the control box shell. In addition, the contact position of the moving block and the clamping block with the side surfaces of the control box shell is limited, and it is impossible to fully overcome the rebound force of the metal plate after bending, which can easily lead to local deformation and cracks at the welding position of the shell, affecting the welding quality of the shell of the door and window control box. Summary of the Invention

[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0037] like Figure 1 As shown, the welding device 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 belong to the prior art and will not be described in detail here. In order to ensure the quality of welding and reduce the local deformation or cracking problems of the control box shell 4 caused by the rebound force during welding, the welding device also includes a limiting component and a fixing component. The limiting component and the fixing component are fitted with each end face 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.

[0038] 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 groups of limit assemblies, and the two groups of limit assemblies are symmetrically arranged about the length direction of the support plate 2. The fixed assembly is arranged 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, first rotate the fixed assembly to push the control box shell 4 from the end where the fixed assembly is located to the support plate 2. An adjusting member 3 is connected to the fixed assembly, and a driving member 35 is provided between the adjusting member 3 and the fixed assembly. The adjusting member 3 is connected to the fixed assembly through the driving member 35. The adjusting member 3 rotates with the welding base 1. The driving member 35 can be a cylinder. After the fixed assembly is adjusted to a vertical state with the adjusting member 3, the fixed assembly can be pushed to move along the length direction of the support plate 2 by controlling the extended length of the piston rod of the driving member 35. Here, the side of the control box shell 4 opposite to the fixing component is the front side, and the side facing the front side of the control box shell 4 is the front side. The driving member 35 is used to push the fixing component to fit with the front side of the control box shell 4. The two groups of limiting components are respectively used to fit with the two opposite sides of the control box shell 4, and the spacing between the two groups of limiting components can be adjusted to adapt to the width of the control box shell 4.

[0039] like Figure 2 、 Figure 6 and Figure 7As shown, the limiting assembly includes a limiting member 21 and a limiting member 22. The limiting member 21 is longitudinally slidably assembled on the support bracket 2, and the limiting member 22 is also longitudinally slidably matched on the support bracket 2. The lower end surface of the support bracket 2 is fixed with a driving member 2, and the driving member 2 can be a motor. The limiting members 1 21 of the two sets of limiting assemblies are both longitudinally fixed relative to the protruding end of the driving member 2, and there is a limiting member 1 21 that can slide relative to the driving member 2 along the width direction of the support bracket 2. Specifically, the protruding end of the driving member 2 can be fixed with a connecting plate 24. The two limiting members 21 both pass through the support bracket 2 and extend to the lower side of the support bracket 2. One limiting member 1 21 is fixed to the connecting plate 24, and the other limiting member 1 21 slides with the support bracket 2 and the connecting plate 24 at the same time along the width direction of the support bracket 2. The welding device also includes a driving member 3 25. A mounting plate is fixed to one side of the support bracket 2, and the driving member 3 25 is mounted on the mounting plate. The driving member 3 25 can be a cylinder, and the limit member 1 21 that slides with the support bracket 2 is fixed relative to the protruding end of the driving member 3 25. By controlling the driving member 3 25, the two groups of limit components can be pushed closer or farther away to adapt to the width of the control box shell 4 of different models. The limit member 22 slides with the limit member 1 21 along the length direction of the support bracket 2 and is elastically connected. The limit member 1 21 and the limit member 2 22 can be elastically connected by a spring, and the limit member 2 22 is movably abutted against the fixed component on the lower side of the support bracket 2, so that after the driving member 1 35 pushes the fixed component to move backward until it abuts against the limit member 2 22, the two limit members 22 are pushed backward synchronously. The limit member 2 22 slides relative to the limit member 1 21 along the length direction of the support bracket 2, so that the overall length of the limit member 2 22 and the limit member 1 21 can be adjusted to adapt to the length of the control box shell 4, while avoiding the limit member 2 22 from blocking the side edges of the control box shell 4 to be welded.

[0040] like Figure 6 and Figure 7As shown, when the control box shell 4 is welded, the two groups of limiting components also limit the upper end face and the rear end face of the control box shell 4 at the same time. The limiting member 1 21 is provided with an "L"-shaped limiting portion 1 211, and the limiting member 2 22 is provided with an "L"-shaped limiting portion 221. The limiting portion 1 211 and the limiting portion 2 221 are both opposite to the rear end face and the upper end face of the control box shell 4 at the same time, and the limiting portion 221 is slidably matched with the limiting portion 1 211 along the length direction of the supporting plate 2 on the upper side of the control box shell 4. The limiting portion 1 211 and the limiting portion 2 221 can directly abut the upper end face of the control box shell 4 to the control box shell 4. The upper end face is fixed, and can also be fixed by abutting against the upper end face of the control box shell 4 through a pressing block 23. A pressing block 23 is fixed to the lower side of each of the limiting part 1 211 and the limiting part 2 221. The pressing block 23 is located on the upper side of the control box shell 4 and is opposite to the upper end face of the control box shell 4. When the limiting part 1 21 moves downward, the two pressing blocks 23 are driven to move downward until the pressing blocks 23 are in contact with the upper end face of the control box shell 4. The pressing block 23 is set in a "T" shape, that is, it includes a connecting portion and an abutting portion. The connecting portion is set perpendicular to the abutting portion. The connecting portion is connected to the limiting part 1 211 or the limiting part 221, and the abutting portion is set horizontally below the connecting portion. When the limiting part 1 211 and the limiting part 2 221 move downward, the pressing block 23 is driven to move downward until the abutting portion of the pressing block 23 abuts against the upper end face of the control box shell 4, thereby fixing the control box shell 4 in the vertical direction.

[0041] The two limiting parts 21 are also fixed with a guide part 212 opposite to the rear side of the control box shell 4. The two guide parts 212 are slidably inserted along the width direction of the support bracket 2. The guide part 212 is "L" shaped. The two guide parts 212 fit the rear end of the control box shell 4 to limit and fix the control box shell 4.

[0042] like Figure 4 and Figure 8As shown, the fixing assembly includes a fixing part 1 31, a fixing part 2 32, a guide part 1 33 and a guide part 2 34. The fixing part 1 31 and the fixing part 2 32 slide together along the width direction of the support plate 2. The guide part 1 33 slides together with the fixing part 1 31 longitudinally and is elastically connected. The guide part 1 33 and the fixing part 1 31 can be elastically connected by a spring. Specifically, a spring can be arranged between the guide part 1 33 and the fixing part 1 31. The spring is arranged along the sliding direction of the fixing part 1 31 relative to the guide part 1 33, and the two ends of the spring are respectively connected to the fixing part 1 31 and the guide part 1 33 to achieve an elastic connection between the two. The guide member 2 34 is longitudinally slidably matched with the fixing member 2 32, and the guide member 1 33 is slidably matched with the guide member 2 34 along the width direction of the support plate 2. The fixing member 1 31 and the fixing member 2 32 are both slidably matched with the support plate 2 along the length direction of the support plate 2. The lower end of the fixing member 1 31 extends to the lower side of the support plate 2 and is fixed with a connecting portion 1 311. The lower end of the fixing member 2 32 extends to the lower side of the support plate 2 and is fixed with a connecting portion 2 321. The connecting portion 1 311 and the connecting portion 2 321 are respectively used for movable limiting with the two limiting members 22. Specifically, the front side of the limiting member 2 22 is fixed with a connecting portion Part three 222, connecting part three 222 is located on the lower side of the support plate 2, and the two connecting parts three 222 are respectively opposite to connecting part one 311 and connecting part two 321, so that after connecting part one 311 and connecting part two 321 abut against the two limiting parts two 22, the two limiting parts two 22 are pushed to move backward synchronously along the length direction of the support plate 2, and when the driving part three 25 drives the two groups of limiting components to be relatively close, the fixing part one 31 and the fixing part two 32 are synchronously approached with the approach of the two groups of limiting components, and when the limiting part moves downward, the fixing part one 31 and the fixing part two 32 are driven to move downward synchronously through the connecting part three 222.

[0043] like Figure 2 and Figure 4 As shown, the adjusting member 3 is located at the rear side of the fixed assembly, the adjusting member 3 is plate-shaped, and the lower end of the adjusting member 3 is hinged to the welding base 1 through a hinge, and the driving member 35 is installed on the adjusting member 3. The driving end of the driving member 35 is fixed to the guide member 33. When the control box shell 4 is pushed in or pulled out of the support tray 2, the driving member 35 is first driven to pull the fixed assembly close to the adjusting member 3, and then the adjusting member 3 is rotated. The fixed assembly rotates 90° with the adjusting member 3, and the control box shell 4 can be taken in and put in.

[0044] The working process of the welding device provided by the present invention is as follows: Rotate the adjusting member 3 so that the adjusting member 3 drives the fixing assembly to rotate to a horizontal state relative to the welding base body 1. The control box shell 4 to be welded is placed on the support tray 2 from the end where the fixing assembly is located by staff or other grabbing and moving equipment. Then rotate the adjusting member 3 to reset it. The control box shell 4 is located in the space formed by the support tray 2, the fixing assembly and the two sets of limiting assemblies. By adjusting the driving member 1 35, the driving member 2 and the driving member 3 25, the fixing assembly and the two sets of limiting assemblies are gradually adapted to the size of the control box shell 4 and fit with the end faces of the control box shell 4.

[0045] When the cam 214 is in contact with the two connecting parts 322, the two limit members 222 move synchronously along the length direction of the support plate 2 with the fixing assembly, and the fixing assembly pushes the control box shell 4 to move backward after contacting the control box shell 4, and the control box shell 4 stops moving after it moves to fit with the guide part 212. The control box shell 4 moves into place in the length direction of the support plate 2, and the limit member 22 slides relative to the limit member 1 21 during the movement of the fixing assembly. The overall length of the limit member 1 21 and the limit member 2 22 is automatically adjusted to match the length of the control box shell 4 on both sides of the control box shell 4. At the same time, the limit member 221 slides relative to the limit member 1 211 along the length direction of the support plate 2, and the overall length of the limit member 2 221 and the limit member 1 211 is automatically adjusted to match the length of the control box shell 4 on the upper end face of the control box shell 4.

[0046] Then, the driving member three 25 is started, and the driving member three 25 pushes a limiting member one 21 to move along the width direction of the support tray 2. The limiting member two 22 moves synchronously with the limiting member one 21. Under the abutment action of the connecting part two 321 and the connecting part three 222, the fixing member two 32 moves synchronously with the limiting member two 22. The overall width of the fixing member two 32 and the fixing member one 31 is automatically adjusted to adapt to the width of the control box shell 4. The limiting member two 22 that slides with the protruding end of the driving member three 25 slides relative to the other limiting member two 22 along the width direction of the support tray 2. The overall length of the two guide parts 212 is automatically adjusted to adapt to the width of the control box shell 4 at the rear end face of the control box shell 4.

[0047] Start driving part 2 again, driving part 2 drives two limiting parts 1 21 to move downward synchronously through connecting plate 24, limiting part 22 moves downward synchronously with limiting part 1 21, and drives limiting part 1 211 and limiting part 2 221 to move downward until pressing block 23 abuts against the upper end face of control box shell 4, and the height of limiting component and fixing component automatically adapts to the height of control box shell 4 and is adjusted, thus completing the limiting operation on each side of control box shell 4, and at the same time avoiding the blocking of side edges of control box shell 4 to be welded by limiting component and fixing component, and finally starting welding mechanism to weld each side edge of control box shell 4 in turn, so as to fully limit control box shell 4 without affecting the welding operation of control box shell 4.
