Description

Technical Field

[0001] The utility model relates to the technical field of door and window production, in particular to an automatic deviation-correcting seamless welding device for doors and windows. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extrusion profiles as frames, stiles, and sash materials, which are simply called aluminum doors and windows. Aluminum alloy doors and windows include those with aluminum alloy as the load-bearing members (members that bear and transfer their own weight and loads) and those combined with wood or plastic, which are simply called aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows. Aluminum alloy doors and windows need to be welded using a welding device; in existing welding devices, most use a single welding gun to weld doors and windows. The transition smoothness of the welding gun at the corners of the doors and windows is relatively poor, the welding quality is not good, and during the welding process, it is impossible to blow air and cool the welded parts of the doors and windows, and the doors and windows are extremely easy to deform under the influence of high temperature, resulting in poor production quality.

[0003] After retrieval, a seamless welding device for doors and windows disclosed in the prior art (Publication No.: CN216990555U) records that "support seats A are installed at both sides of the front surface and both sides of the rear surface of the workbench. Lead screws A are installed at the middle gap positions between the two support seats A on both sides. Slide blocks B are sleeved on the outer surfaces of the two lead screws A. Brackets A are installed at the top positions of the two slide blocks B. Support seats B are installed at both sides of the workbench near the front surface and near the rear surface. Lead screws B are installed at the middle gap positions between the two support seats B on both sides. Slide blocks A are sleeved on the outer surfaces of the two lead screws B. Brackets B are installed at the top positions of the two slide blocks A. Displacement sleeves are sleeved on both sides of the outer surfaces of the brackets A and B. Electric telescopic devices are installed at the middle positions of the bottoms of the displacement sleeves. The output shafts of the electric telescopic devices are installed with welding heads."; by setting the displacement motor A, lead screw A, lead screw B, displacement motor B, bracket A, bracket B, and welding head, the device achieves the effect of synchronously welding the four sides of the doors and windows. By pushing the welding head downward through the electric telescopic device, the doors and windows can be quickly welded, and the welding quality can be improved. However, in this device, the welding head is arranged below the displacement sleeve through the electric telescopic device, and the electric telescopic device lacks a corresponding auxiliary deviation-correcting structure. When the electric telescopic device and the welding head are displaced during use, workers cannot quickly detect it, which will then reduce the welding quality of the doors and windows, and manual deviation correction by workers is still required later, which not only affects the welding efficiency but also reduces the product quality.

[0018] Referring to Figures 1 to 4 As shown in the figure, the utility model provides an automatic deviation-correcting seamless welding device for doors and windows, including: a displacement sleeve 2. The base main body 1 is slidably connected to the bracket 3 through a lead screw, and the displacement sleeve 2 is slidably and fixedly connected to the bracket 3 through a lock. Moreover, the lower surface of the displacement sleeve 2 is connected to the welding head 12 through an electric telescopic device 8. The two ends of the lower surface of the displacement sleeve 2 are symmetrically connected to a vertical plate 4 and a positioning rod 9 respectively. A guide groove 5 is formed on the surface of the vertical plate 4, and a guide block 6 is slidably connected in the guide groove 5. One side of the guide block 6 close to the positioning rod 9 is fixedly connected to a fixing plate 7. The lower end of the fixing plate 7 is fixedly connected to a fixing ring 11 through a fixing block 10. The fixing ring 11 is fixedly connected to the upper surface of the welding head 12. At the same time, one end of the fixing plate 7 away from the guide block 6 is slidably connected to the positioning rod 9 through a positioning hole, and the lower end of the positioning rod 9 is slidably connected to a positioning groove formed on the surface of the fixing plate 7.

[0019] In this embodiment, when the electric telescopic device 8 drives the welding head 12 to move through the telescopic rod, the welding head 12 will drive the fixing plate 7 to move synchronously through the fixedly connected fixing ring 11 and fixing block 10. One side of the fixing plate 7 slides on the surface of the positioning rod 9 through the positioning hole, and the other side of the fixing plate 7 drives the fixedly connected guiding block 6 to move synchronously. The guiding block 6 is slidably connected in the guiding groove 5 opened on the vertical plate 4, so that both sides of the fixing plate 7 can be restricted by the moving path at the same time, and then it can be ensured that the moving path of the fixing plate 7 is vertically downward. Therefore, when there is a deviation trend in the moving paths of the telescopic rod of the electric telescopic device 8 and the welding head 12, the fixing plate 7 can automatically correct the moving paths of the telescopic rod and the welding head 12 through the fixing block 10 and the fixing ring 11, so as to ensure that the welding head 12 can move vertically downward, and further ensure the welding effect of the seamless welding device on the doors and windows, reduce the probability of subsequent manual maintenance, and thus improve the welding efficiency and welding quality of the seamless welding device.

[0020] At the same time, the relevant structure of the base body 1 in this application, the connection relationship between the base body 1, the bracket 3, the displacement sleeve 2, the electric telescopic device 8 and the welding head 12, and the relevant working principle of seamless welding of doors and windows are all existing mature technologies, which have been fully disclosed in a seamless welding device for doors and windows (Publication No.: CN216990555U).

[0021] As a preferred embodiment, there are two groups of vertical plates 4. Both groups of vertical plates 4 are in an isosceles trapezoid structure, and the end with the larger size of the vertical plate 4 is fixedly connected to the lower surface of the displacement sleeve 2. At the same time, the displacement sleeve 2 and the vertical plate 4 are combined to form a U-shaped structure.

[0022] In this embodiment, as Figure 2 、 Figure 3 and Figure 4 , the end with the larger size of the vertical plate 4 is fixedly connected to the lower surface of the displacement sleeve 2, which can then assist in enhancing the stability of the connection between the lower surface of the displacement sleeve 2 and the vertical plate 4 and reducing the probability of the vertical plate 4 shifting in position.

[0023] As a preferred embodiment, the guiding groove 5 opened on the surface of the vertical plate 4 is in a rectangular structure, and the guiding block 6 slidably connected in the guiding groove 5 is in an I-shaped structure, and the sizes of the guiding groove 5 and the guiding block 6 are adapted to each other.

[0024] In this embodiment, as Figure 2 、 Figure 3 and Figure 4, the sizes of the guiding groove 5 and the guiding block 6 are adapted to each other, which can then assist in enhancing the stability of the guiding block 6 during movement, reducing the probability of the guiding block 6 shaking during movement, and the setting of the guiding block 6 can also assist in detecting whether the vertical plate 4 is bent or deformed. When the vertical plate 4 is bent or deformed, the guiding block 6 cannot pass through the deformed position. Furthermore, the guiding block 6 can restrict the movement of the welding head 12 through the fixing plate 7, the fixing block 10, and the fixing ring 11. Therefore, it is convenient for workers to quickly notice and reduce the probability of the welding quality of the doors and windows deteriorating.

[0025] As a preferred embodiment, there are two groups of positioning rods 9. Both groups of positioning rods 9 are in an L-shaped structure, and the end face of the positioning rod 9 is in a square structure. At the same time, the bent part of the positioning rod 9 is fixedly connected to the lower end of the surface of the vertical plate 4.

[0026] In this embodiment, as shown in Figure 2 and Figure 4 , the structural setting of the positioning rod 9 enables the lower ends of the vertical plate 4 and the positioning rod 9 to be fixedly connected to each other, which then assists in enhancing the structural strength between the vertical plate 4 and the positioning rod 9, thereby assisting in reducing the probability of the vertical plate 4 or the positioning rod 9 being bent or deformed, and ensuring the automatic deviation correction effect of the fixing plate 7, the fixing block 10, and the fixing ring 11 on the movement path of the welding head 12.

[0027] As a preferred embodiment, the fixing plate 7 is composed of a horizontal plate and a vertical plate. The fixing plate 7 as a whole is in a T-shaped structure, the horizontal plate is in a rectangular structure, and the vertical plate and the positioning groove together form a concave-shaped structure.

[0028] In this embodiment, as shown in Figure 2 and Figure 3 , the structural setting at both ends of the horizontal plate enables the two ends of the upper surface of the fixing plate 7 to be slidably connected to the vertical plate 4 and the positioning rod 9 respectively, which can then effectively enhance the stability of the fixing plate 7 during sliding, and further can assist in enhancing the automatic deviation correction effect of the fixing plate 7 on the movement path of the welding head 12 through the fixing block 10 and the fixing ring 11.

[0029] As a preferred embodiment, the positioning holes correspondingly opened on the upper surface of the fixing plate 7 at the position relative to the positioning rod 9 are in a square structure, and the sizes of the positioning holes and the positioning rod 9 are adapted to each other. At the same time, the sizes of the bent part of the positioning rod 9 and the positioning groove are adapted to each other.

[0030] In this embodiment, as shown in Figure 2 and Figure 3, the positioning holes and positioning grooves are respectively adapted to the corresponding parts of the positioning rod 9 in terms of size, thereby being able to assist in reducing the probability of shaking between the fixing plate 7 and the positioning rod 9 and enhancing the stability when the fixing plate 7 moves. Moreover, the setting of the positioning holes and positioning grooves enables the fixing plate 7 to also assist in detecting the positioning rod 9 accordingly. When the positioning rod 9 is bent and deformed, the fixing plate 7 can stay at the deformed part, restricting the downward movement of the welding head 12 and facilitating the improvement of the worker's detection speed.

[0031] As a preferred embodiment, the fixing block 10 fixedly connected to the lower end of the fixing plate 7 has a square structure, while the fixing ring 11 fixedly connected to the end of the fixing block 10 away from the fixing plate 7 has a circular ring structure, and the inner diameter of the fixing ring 11 is adapted to the diameter of the telescopic rod of the electric telescopic device 8.

[0032] In this embodiment, as Figure 2 and Figure 4 , the setting of the fixing ring 11 and the fixing block 10 enables the fixing plate 7 to directly and real-time correct the moving path of the welding head 12, avoiding the problem of deviation of the moving path of the welding head 12 and ensuring the accuracy of the welding position of the welding head 12. At the same time, the fixing ring 11 is adapted to the size of the telescopic rod of the electric telescopic device 8, which can assist in reducing the probability of the telescopic rod being bent or the moving path deviating.

[0033] The automatic deviation-correcting seamless welding device for doors and windows of the present utility model, through the cooperation of the vertical plate 4, the positioning rod 9, the guiding block 6, the fixing plate 7, the fixing block 10 and the fixing ring 11, enables the lower surface of the displacement sleeve 2 to automatically correct the telescopic rod of the electric telescopic device 8 and the moving path of the welding head 12, thereby ensuring that the welding head 12 can always move vertically downward, improving the accuracy of the welding position of the welding head 12 and ensuring the welding quality of the device.
