Abstract
Description
Technical Field
[0001] This utility model relates to the field of brazing fixtures for coolers, and in particular to a general-purpose brazing fixture for coolers. Background Technology
[0002] Typically, brazing of coolers requires specialized brazing fixtures to ensure proper brazing gaps during the process and to prevent defects such as deformation after brazing. Austenitic stainless steel, with its excellent thermal strength, low specific heat capacity, and good thermal conductivity, is usually the preferred material for brazing fixtures. However, austenitic stainless steel is expensive, and the brazing fixtures are not universal (dedicated brazing fixtures), meaning each cooler requires a specific type of fixture, resulting in significant waste and high brazing costs.
[0003] Therefore, there is an urgent need to propose a universal brazing fixture for coolers to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a universal brazing fixture for coolers. This universal brazing fixture can be used for coolers of different sizes, has strong versatility, and has high cooler installation efficiency. Compared with dedicated brazing fixtures, it reduces the brazing cost of coolers.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] General brazing fixtures for coolers include:
[0007] Base;
[0008] A first movable plate is movably placed on the base. The shape of the first movable plate is adapted to the bottom shape of the cooler, so that the cooler can be placed vertically on the first movable plate.
[0009] The second movable plate is adapted to the top shape of the cooler and can be movably pressed onto the top of the cooler, so that the cooler is clamped and fixed by the first movable plate and the second movable plate.
[0010] As an optional technical solution for general brazing fixtures for coolers, the first movable plate is provided with a clearance hole, which is adapted to the flange at the bottom of the cooler to avoid the flange.

[0033] This embodiment provides a universal brazing fixture for coolers. This universal brazing fixture can be used for coolers of different sizes, has strong versatility, and has high cooler installation efficiency. Compared with dedicated brazing fixtures, it reduces the brazing cost of coolers.
[0034] Specifically, such as Figures 1 to 4 As shown, the universal brazing fixture for the cooler includes a base 100, a first movable plate 200, and a second movable plate 300. The first movable plate 200 can be movably placed on the base 100, and its shape is adapted to the bottom shape of the cooler, allowing the cooler to be placed vertically on the first movable plate 200. The second movable plate 300 is adapted to the top shape of the cooler, and its shape can be movably pressed against the top of the cooler, so that the cooler is clamped and fixed by the first movable plate 200 and the second movable plate 300.
[0035] Based on the above design, the shape of the first movable plate 200 is adapted to the bottom shape of the cooler, and the shape of the second movable plate 300 is adapted to the top shape of the cooler. The first movable plate 200 can be movably placed on the base 100, and the second movable plate 300 can be movably pressed against the top of the cooler. The cooler is clamped and fixed by the first movable plate 200 and the second movable plate 300, ready for subsequent welding operations. On the one hand, both the first movable plate 200 and the second movable plate 300 are movable, making disassembly and assembly simple, thus increasing the installation efficiency of the cooler. On the other hand, since both the first movable plate 200 and the second movable plate 300 are adapted to the cooler, for coolers of different sizes, the first movable plate 200 and the second movable plate 300 can be directly replaced, making the universal brazing fixture for the cooler highly adaptable, thereby reducing the brazing cost of the cooler. In actual welding operations, firstly, select a first movable plate 200 that matches the size of the cooler and place the first movable plate 200 on the base 100. Then, place the cooler on the first movable plate 200. The base 100 supports the first movable plate 200 and the cooler. Then, select a second movable plate 300 that matches the cooler and press the second movable plate 300 onto the top of the cooler, so that the cooler is clamped and fixed by the first movable plate 200 and the second movable plate 300, waiting for subsequent welding.
[0036] Optionally, the base 100 is provided with a plurality of weight-reducing holes 120, which are evenly distributed along a first direction, the length direction of the cooler, which can save materials and reduce the weight of the base 100.
[0037] For example, the number of weight-reducing holes 120 can be two, three, or five, etc.
[0038] In this embodiment, the base 100 includes a top plate and two side plates. The two side plates are arranged opposite to each other and both extend along a first direction. The top edges of the two side plates are connected to the top plate. The weight reduction hole 120 is a through hole on the top plate.
[0039] Optionally, the base 100 has connecting holes 110 on both sides along the second direction. In this embodiment, the connecting holes 110 are located on the side plate of the base 100 and are used to connect two adjacent bases 100. The second direction is the width direction of the cooler. When welding a cooler with a larger width, the width of the first movable plate 200 is larger, so multiple bases 100 can be spliced together to jointly support the wider first movable plate 200, resulting in high support stability. When welding a cooler with a smaller width, the width of the first movable plate 200 is smaller, so a single base 100 is sufficient, saving space. Therefore, the universal brazing fixture for coolers in this embodiment can be used individually or spliced together, making it highly versatile. Optionally, the second movable plate 300 has an avoidance notch to avoid the top components of the cooler.
[0040] Optionally, the first movable plate 200 is provided with a clearance hole 210, which is adapted to the flange at the bottom of the cooler to avoid damaging the flange at the bottom of the cooler.
[0041] In this embodiment, a gap is left between the base 100 and the first movable plate 200, allowing the flange to pass through the clearance hole 210 and be positioned within the gap; that is, the first movable plate 200 is suspended. Compared to the first movable plate 200 being in contact with the base 100 and the flange being completely positioned within the clearance hole 210, the aforementioned suspended configuration of the first movable plate 200 saves material and reduces weight, while also facilitating the flange's passage through the clearance hole 210 and preventing the flange from being scratched.
[0042] It should be noted that the number of clearance holes 210 is the same as the number of bottom flanges of the cooler, and they correspond one-to-one. In this embodiment, there are two clearance holes 210.
[0043] Furthermore, the general brazing fixture for the cooler also includes a vertical column 400 set in the gap, with both ends of the column 400 abutting against the first movable plate 200 and the base 100 respectively, so as to support the first movable plate 200 and save space.
[0044] There are multiple columns 400, which are spaced apart in the aforementioned gaps. For example, the number of columns 400 can be two, three, five, or eight, etc. Of course, the columns 400 need to be positioned to avoid the clearance hole 210.
[0045] In this embodiment, the column 400 and the first movable plate 200 are detachably connected by screws. Specifically, the screws pass through the first movable plate 200 and are threadedly connected to the column 400.
[0046] It should be noted that, for easier replacement of the first movable plate 200, it is usually pre-connected to all the columns 400 before leaving the factory, forming a single unit. In use, it is placed directly onto the base 100, meaning the column 400 directly abuts against the top surface of the base 100. Of course, the column 400 must also be positioned to avoid the weight-reducing holes 120.
[0047] Furthermore, in order to prevent the column 400 from sliding on the top surface of the base 100, a limiting groove 130 is provided on the top surface of the base 100, and the column 400 is inserted into the limiting groove 130.
[0048] In this embodiment, a limiting groove 130 is provided only for the outermost column 400 located in the first direction (the length direction of the cooler), which reduces the processing cost while satisfying the limiting of the first movable plate 200.
[0049] Optionally, such as Figure 1 , Figure 5 and Figure 6 As shown, in order to achieve the requirement of pressing the cooler with the second movable plate 300, in this embodiment, the general brazing fixture for the cooler also includes a limiting plate 500 and an elastic element 600. The limiting plate 500 is located on the top of the second movable plate 300 and fixed to the base 100. The two ends of the elastic element 600 are respectively connected to the second movable plate 300 and the limiting plate 500. The rebound force of the elastic element 600 presses the second movable plate 300 tightly against the cooler. The limiting plate 500 presses down on the elastic element 600, and then the rebound force of the elastic element 600 presses down on the second movable plate 300 to press the cooler. The buffering effect of the elastic element 600 can prevent damage to the cooler.
[0050] In this embodiment, the elastic element 600 is a spring, and there are multiple springs. For example, the number of springs can be two, three, or five, and the multiple springs are spaced apart along the first direction.
[0051] Furthermore, the limiting plate 500 has a concave groove 530 on the side facing the spring (i.e., the bottom of the limiting plate 500), and one end of multiple springs is locked in the concave groove 530 to prevent the springs from shifting.
[0052] The universal brazing fixture for the cooler also includes two connectors 700, which are located at both ends of the base 100 along a first direction. The two ends of each connector 700 are connected to the base 100 and the limiting plate 500, respectively. The first direction is the length direction of the cooler. The position of the limiting plate 500 is fixed by the two connectors 700. For coolers of different heights, the connection position between the limiting plate 500 and the connectors 700 is adjusted vertically.
[0053] Furthermore, the connector 700 includes a screw and a nut, and the limiting plate 500 has mounting holes at both ends along the first direction. One end of the screw is fixedly connected to the base 100, and the other end passes through the mounting hole and is threadedly connected to the nut. The limiting plate 500 is fixed by the threaded connection between the screw and the nut, which has a good fixing effect and the height adjustment of the limiting plate 500 is simple.
[0054] In this embodiment, the limiting plate 500 has slots 510 at both ends along the first direction, and the screw passes through the slots 510. The slots 510 are easy to process.
[0055] Furthermore, in order to prevent the screw from sliding out of the slot 510, the slot 510 is provided with limit posts 520 on both sides of the second direction to prevent the nut screwed onto the screw from sliding outward, thereby preventing the screw from sliding out of the slot 510.
[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
