Description

Technical Field

[0001] This utility model relates to the technical field of positioning welding devices, specifically to a positioning welding device for welding hooks and water tanks. Background Technology

[0002] As a common facility in bathrooms and kitchens, sinks are widely used for daily cleaning activities such as handwashing, rinsing, and dishwashing. During installation, the sink is supported and hung on the countertop by its horizontal edge extending outwards from its upper end. This horizontal edge directly bears the entire load of the sink body and during use, serving as the primary load-bearing structure. To achieve precise calibration and positioning during sink installation, multiple metal hooks are usually welded to the bottom surface of the horizontal edge of the sink. These hooks do not bear the main load-bearing function but, in conjunction with the mounting brackets or fixed structures under the countertop, limit the horizontal displacement of the sink, ensuring its accurate front-to-back and left-to-right positioning and preventing installation misalignment.

[0003] Currently, welding hooks are mostly done manually. Operators manually place the hook at a designated position on the bottom of the horizontal edge before welding. However, this process has significant drawbacks: before and during welding, the hook lacks an effective positioning and clamping device, relying solely on manual holding or simply resting it against the outer side of the tank for positioning, making it difficult to guarantee consistent and accurate positioning. Especially under the influence of welding thermal stress, the hook is prone to shifting or tilting, resulting in significant post-weld positional deviations.

[0004] Due to inaccurate welding hook positioning, the sink cannot effectively align with the fixed structure under the countertop during actual installation, often resulting in difficulties in sink positioning. This not only affects installation efficiency and appearance quality but may also impact overall installation accuracy and user experience. Utility Model Content

[0005] In view of the technical problems existing in the prior art, the purpose of this utility model is to provide a positioning welding device for welding hooks and water tanks, which realizes accurate and stable positioning of welding hooks on water tanks during welding.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A positioning welding device for a welding hook and a water tank, the water tank including a tank body and a horizontal edge, the horizontal edge being located at the upper end of the tank body and extending outward, a welding hook being located below the horizontal edge, the positioning welding device including a welding hook pressing component, a driving component, a base plate and a water tank positioning baffle, the driving component being mounted on the base plate, the water tank positioning baffle being mounted on the top surface of the base plate, the welding hook pressing component being mounted on the driving end of the driving component, the water tank being able to be flipped upside down and placed on the base plate with the top surface of the horizontal edge abutting against the top surface of the base plate, the water tank positioning baffle being used to calibrate and position the water tank, the driving component driving the welding hook pressing component to press and position the welding hook located on the bottom surface of the horizontal edge.

[0007] As a preferred embodiment, there are multiple welding hooks corresponding to one water tank, and the multiple welding hooks are distributed on the bottom surface of the horizontal edge; the number of welding hooks is the same as the number of welding hook pressing parts, and each driving part is equipped with one welding hook pressing part.

[0008] As a preferred embodiment, the welding hook includes a bonding plate and a calibration positioning plate.

[0009] As a preferred embodiment, the welding hook pressing component includes a mounting plate and two pressing rods. The two pressing rods are arranged in parallel and are respectively fixedly connected to the mounting plate perpendicularly. The mounting plate is installed on the driving end of the driving component. The two pressing rods are respectively distributed at both ends of the bottom surface of the mounting plate. The driving component can drive the two pressing rods to press the two ends of the bonding plate respectively.

[0010] As a preferred embodiment, the inner side of the water tank positioning baffle is in close contact with the outer side of the horizontal edge of the water tank.

[0011] As a preferred option, the upper end of the water tank corresponding to the positioning welding device is rectangular.

Detailed Implementation

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0026] like Figures 1 to 4 As shown, a positioning welding device for a welding hook 4 and a water tank 1 is disclosed. The water tank 1 includes a tank body 2 and a horizontal edge 3. The horizontal edge 3 is located at the upper end of the tank body 2 and extends outward by 1 cm to 3 cm. The welding hook 4 is located below the horizontal edge 3. The positioning welding device includes a welding hook pressing component 5, a driving component 6, a base plate 7, and a water tank positioning baffle 8. The driving component 6 is mounted on the base plate 7, the water tank positioning baffle 8 is mounted on the top surface of the base plate 7, and the welding hook pressing component 5 is mounted on the driving end 9 of the driving component 6. The water tank 1 can be flipped upside down and placed on the base plate 7 with the top surface of the horizontal edge 3 in contact with the top surface of the base plate 7. The water tank positioning baffle 8 is used to calibrate and position the water tank 1. The driving component 6 drives the welding hook pressing component 5 to press and position the welding hook 4 located on the bottom surface of the horizontal edge 3. This achieves rapid, accurate, and stable positioning of the welding hook 4 on the water tank 1. The positioning welding device significantly improves the positional accuracy and consistency of the welding hook 4, reduces human error, and improves welding quality and production efficiency.

[0027] The driving component 6 is a pneumatic cylinder, hydraulic cylinder, or electric cylinder. In this embodiment, the driving component 6 is preferably a pneumatic cylinder, and the driving end 9 of the pneumatic cylinder is a piston rod.

[0028] There are multiple welding hooks 4 corresponding to one water tank 1, and the multiple welding hooks 4 are distributed on the bottom surface of the horizontal edge 3; the number of welding hooks 4 is the same as the number of welding hook pressing parts 5, and one welding hook pressing part 5 is installed for each cylinder. Ensure that the pressing strength of each welding hook pressing part 5 is uniform.

[0029] The welding hook 4 includes a bonding plate 10 and a calibration positioning plate 11. The bonding plate 10 and the calibration positioning plate 11 are vertically fixedly connected. The bonding plate 10 is bonded to the bottom surface of the horizontal edge 3, and the inner side of the bonding plate 10 is closely aligned with the outer side of the tank 2. The welding hook pressing component 5 presses against the bonding plate 10. The bonding plate 10 and the bottom surface of the horizontal edge 3 of the tank 1 are fixedly connected by laser welding. Specifically, after the laser beam penetrates the bonding plate 10 of the welding hook 4, it causes the bonding plate 10 and the bottom surface material of the horizontal edge 3 to partially melt and fuse. After cooling, the two are metallurgically bonded. Laser welding can be precisely operated by an industrial robot.

[0030] The welding hook pressing component 5 includes a mounting plate 12 and two pressing rods 13. The two pressing rods 13 are arranged in parallel and are vertically fixed to the mounting plate 12. The mounting plate 12 is bolted to the top surface of the piston rod of the cylinder. The two pressing rods 13 are distributed at both ends of the bottom surface of the mounting plate 12. The cylinder can drive the two pressing rods 13 to press the two ends of the bonding plate 10 respectively. When the cylinder is activated, the two pressing rods 13 press down synchronously, acting on the two ends of the bonding plate 10 respectively, forming a two-point pressing positioning. This design can effectively prevent the bonding plate 10 from warping or shifting during the pressing process, ensuring that the welding hook 4 remains flat and in contact, and improving the welding quality.

[0031] The water tank positioning baffle 8 includes a baffle 14 and a flat plate 15, which are vertically fixedly connected. The flat plate 15 is bolted to the base plate 7, and the inner side of the baffle 14 is in close contact with the outer side of the horizontal edge 3 of the water tank 1. In this embodiment, multiple water tank positioning baffles 8 are preferably set on two adjacent sides of the water tank 1, corresponding to the positions of one wide side and one long side of the water tank 1. By setting positioning baffles 14 in two mutually perpendicular directions, a right-angle positioning reference is formed. This makes it convenient for operators to quickly and accurately position the water tank 1 when placing it upside down on the base plate 7, simply by placing the outer side of its horizontal edge 3 against the corresponding positioning baffle 14.

[0032] In use, start the cylinder, extend the piston rod upwards, and move the welding hook pressing component 5 upwards. First, flip the water tank 1 upside down and place it on the base plate 7, so that the top surface of its horizontal edge 3 is in contact with the base plate 7, and the outer side of the horizontal edge 3 is pressed against the water tank positioning baffle 8, completing the positioning of the water tank 1. Then, place each welding hook 4 at the designated position on the bottom surface of the horizontal edge 3, with the welding hook 4 close to the outer side of the tank body 2. Visually, the welding hook 4 is positioned below the pressing rod 13. Operate the cylinder, and the piston rod moves downwards, causing the welding hook pressing component 5 to move downwards. The pressing rod 13 presses the bonding plate 10 of the welding hook 4 firmly against the bottom surface of the horizontal edge 3. At this time, the welding hook 4 is firmly and accurately pressed and positioned, and the welding operation can be carried out. After welding is completed, the piston rod of the cylinder extends upwards, causing the welding hook pressing component 5 to release upwards, and the water tank 1 can be removed. Example 2

[0033] like Figures 5 to 7As shown, the difference between this embodiment and Embodiment 1 is that the upper end of the tank body 2 of the water tank 1 corresponding to the positioning welding device is rectangular, and the horizontal edge 3 is also rectangular. The upper width of different models of water tank 1 is the same but the length is different. Correspondingly, the overall width of the horizontal edge 3 of different models of water tank 1 is the same but the length is different. A base 16 is set below the base plate 7, and multiple support columns 17 are fixedly set between the base 16 and the base plate 7. In this embodiment, it is preferred that there are four support columns 17, which are distributed at the four corners of the rectangular base plate 7. A rectangular opening 18 is opened at one end of the base plate 7 in the length direction. The width of the rectangular opening 18 is larger than the overall width of the horizontal edge 3. The narrow width ensures that there are positions on the base plates 7 on both sides of the length of the water tank 1 to support the water tank 1 and install the corresponding drive components 6. A slide rail 19 is provided on the base 16, which is located below the rectangular opening 18. The length of the slide rail 19 is the same as the length of the base 16. A slide seat 20 is slidably connected to the slide rail 19. The drive component 6 located at the rectangular opening 18 is installed on the slide seat 20. The rectangular opening 18 avoids the slide seat 20, drive component 6 and welding hook pressing component 5 installed on the slide rail 19, so that the position of the slide seat 20 in the length direction can be adjusted along the slide rail 19 to match the installation position of the welding hook 4 on water tanks of different lengths. It is suitable for water tanks of various lengths.

[0034] An inverted T-shaped groove 23 is formed on the slide rail 19, extending along the length of the slide rail 19. The lower cross-section of the slide block 20 is correspondingly inverted T-shaped structure 24, which is located within the inverted T-shaped groove 23 and is slidably connected to the inverted T-shaped groove 23. The slide block 20 is also provided with a sliding plate 25, which is fixedly mounted on the top of the inverted T-shaped structure 24. A threaded hole is formed on the sliding plate 25, and a bolt is screwed into the threaded hole. The end of the bolt presses against the slide rail 19 to fix the relative position of the slide block 20 and the slide rail 19.

[0035] The base plate 7 has elongated holes 21, the length of which is the same as that of the base plate 7. These holes are located at both ends of the base plate 7 along its length, outside the horizontal edge 3. The elongated holes 21 are used to install the drive components 6 at both ends of the water tank 1 along its length. Each drive component 6 has three elongated holes 21; two are used to mount the cylinder via bolts, and the third is for the piston rod to pass through. Because the placement of the welding hook 4 may differ between different models of water tank 1, the installation positions of the cylinder and the welding hook pressing component 5 can be adjusted via the elongated holes 21, making it compatible with various models of water tank 1 and further enhancing the versatility and flexibility of the positioning welding device.

[0036] The base 16 is longer than the base plate 7. Two lifting rings 22 are installed on the base 16, located at both ends along its length. The device can be moved as a whole using a crane or forklift via the lifting rings 22, improving operational efficiency and safety.

[0037] When using, if it is necessary to replace the water tank 1 with a different model, the installation position of the drive component 6 is adjusted through the elongated hole 21 according to the length of the water tank 1 and the placement position of the welding hook 4, and then the slide block 20 on the slide rail 19 is adjusted to complete the adjustment of the position of the welding hook pressing component 5.

[0038] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
