Description

Technical Field

[0001] This utility model relates to the field of curing fixtures, and in particular to a water tank clamping curing fixture. Background Technology

[0002] Currently, most water heating devices on the market are flat or rectangular, which have significant limitations in terms of installation space and internal liquid flow, making it impossible to achieve large flow rates. Therefore, a hexagonal water tank was developed. However, difficulties were encountered during the curing process of the heating element and the hexagonal water tank. Flat and rectangular water tanks can be subjected to force on the same side during curing, but hexagonal water tanks cannot use traditional curing methods because they can only be clamped from both sides. This means that curing must be repeated three times to complete one product. At the same time, because force is only applied from both sides, the water tank can be deformed if the clamping pressure is not properly controlled. Therefore, this clamping and curing fixture was designed, which greatly improves production efficiency, reduces repetitive labor, and increases product qualification rate. Utility Model Content

[0003] The purpose of this utility model is to provide a water tank clamping and curing fixture, which has the same number of baffles as the side of the water tank, and can clamp all the heating cores on the outer wall of the water tank at one time for curing, thereby improving production efficiency.

[0004] To solve the above technical problems, the following technical solution is adopted: This utility model provides a water tank clamping and curing fixture, including a base, a limiting sleeve, baffles, and hose clamps. The limiting sleeve is mounted on the base. The baffles are disposed on the outside of the water tank, to which the heating element is attached. The water tank has a polygonal structure, and the number of baffles is the same as the number of outer wall surfaces of the water tank. The hose clamps are used to clamp several of the baffles to the outside of the water tank. The water tank, with the baffles and hose clamps installed, is positioned on the limiting sleeve, which is located outside the baffles. The limiting sleeve restricts the relative position between the baffles, the heating element, and the water tank, preventing misalignment between them.

[0005] Optionally, the water tank has a hexagonal structure, and a heating core is attached to each of the outer side walls of the water tank; six baffles are correspondingly arranged outside the heating cores and fixed in position with the hose clamps. When the six baffles are closed, they form a perfect circle, which facilitates the locking of the hose clamps.

[0006] Optionally, the side of the baffle that contacts the heating core is a groove, and the other side is a six-part arc surface. The six baffles form a cylindrical structure and are fixedly installed by the hose clamp. The groove is used to determine the position of the heating core.

[0007] Optionally, the inner surface of the groove is a plane, and the plane fits the surface of the heating core.

[0008] Optionally, two hose clamps are provided, and the two hose clamps are arranged at intervals around the periphery of the stop bar.

[0009] Optionally, the length of the baffle is greater than the core length of the heating element.

[0010] Optionally, the base is provided with a slot for positioning and installing the limiting sleeve, and the center of the slot is a through hole extending to the other side of the base. The through hole is used to install the water nozzle on the water tank.

[0011] Optionally, the limiting sleeve is a cylindrical structure with openings at both ends. A first step and a second step are provided on one end inside the limiting sleeve. The first step is used to limit the position of the water tank, and the second step is used to limit the position of the baffle.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: The water tank clamping and curing fixture provided by this utility model clamps the heating core on the water tank by setting the same number of baffles as the side surface of the water tank. It can clamp all the heating cores on the water tank at one time, improving production efficiency. The baffles are installed by clamping with pipe clamps, so that the heating core is tightly attached to the outer wall of the water tank, avoiding the thick glue between the heating core and the water tank from affecting the heat transfer efficiency of the heating core, and also preventing the heating core from shifting.

[0017] Example 1

[0018] This embodiment provides a clamping and curing fixture for a water tank 6, including a base 1, a limiting sleeve 2, a stop bar 3, and a hose clamp 5. The base 1 includes a square plate and support feet located at the four corners of the square plate. A slot 11 is formed at the center of the base 1, which does not extend to the other side of the base 1. A through hole 12 is formed at the center of the slot 11, extending to the other side of the base 1. The limiting sleeve 2 is installed in the slot 11. One end of the limiting sleeve 2 has a large hole, and the other end has a smaller hole. The end of the limiting sleeve 2 with the small hole is placed in the slot 11. Inside the end of the small hole, there is a groove that is larger than the small hole but smaller than the large hole at the other end, so that the limiting sleeve 2 has a first step 21 and a second step 22 at the end of the small hole. The first step 21 is the bottom surface of the groove, and the second step 22 is the inner end face of the limiting sleeve 2. The first step 21 contacts and engages with the end of the water tank 6, and the second step 22 contacts and engages with the end face of the stop bar 3.

[0019] In this embodiment, the water tank 6 is hexagonal in structure. Each side wall of the hexagonal water tank 6 is glued with a heating element 4. Water nozzles 61 are connected to both ends of the water tank 6. A water nozzle 61 located at one end of the base 1 passes through a through hole 12 in the base 1. Six baffles 3 are used, forming a cylindrical structure that fits over the water tank 6 with the heating elements 4 glued on. The baffles 3 fix the position of the heating element 4 relative to the water tank 6, preventing the heating element 4 from shifting before the glue between the heating element 4 and the side wall of the water tank 6 has cured. The inner side of the baffle 3 has a groove 31 structure. The interior of the groove 31 is a flat surface that contacts and engages with the surface of the heating element 4, confining the heating element 4 within the groove 31 and preventing it from shifting. The outer side of the baffle 3 is a six-part arc surface 32. After the six baffles 3 are joined together, the outer side forms a perfect circle, which facilitates the installation of the hose clamp 5 on the outside of the baffle 3. The six baffles 3 are clamped to the outside of the water tank 6 by the hose clamp 5, thereby fixing the heating core 4 to the outside of the water tank 6, which facilitates the baking of the glue between the heating core 4 and the water tank 6.

[0020] The heating element 4 includes a core and a wire. The core is attached to the side wall of the water tank 6 with glue. The wire is directed away from the base 1. The length of the baffle 3 is greater than the length of the core. The core is completely covered by the baffle 3, thereby clamping and limiting the core to the outer wall of the water tank 6.

[0021] This embodiment uses two hose clamps 5. The number of hose clamps 5 can be adjusted according to the length of the core. The two hose clamps 5 are evenly spaced and clamped to the outside of the stop bar 3.

[0022] In use, the heating element 4 is glued to the outer wall of the water tank 6. Each side wall of the hexagonal water tank 6 is glued with the heating element 4. Then, the six baffles 3 are set around the outer periphery of the heating element 4. The heating element 4 is located in the groove 31 of the baffle 3 and will not shift. Then, the baffles 3 are locked and fixed with the hose clamp 5, so that the baffles 3 clamp the heating element 4 on the water tank 6. Then, the end without the wire is inserted into the limiting sleeve 2. The limiting sleeve 2 clamps the baffles 3, thereby limiting the relative position of the baffles 3, the heating element 4 and the water tank 6 to prevent them from deflecting. Then, the glue between the heating element 4 and the water tank 6 is dried by baking with a baking device.

[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
