Description

Technical Field

[0001] This utility model belongs to the field of inverter welding technology, and relates to a radiator bracket, mounting structure, and inverter welding machine. Background Technology

[0002] In inverter welding machines, the heat sinks for the secondary-side rectifier diodes are typically conductive. To ensure electrical safety and heat dissipation, the design and use of the heat sink bracket are crucial. Currently, heat sink brackets on the market only offer one mounting height, thus failing to accommodate flexible chassis height designs. Furthermore, due to the heavy weight and susceptibility to deformation of the heat sinks during welding machine assembly, tilting is not permitted; instead, the screws must be manually tightened from the outside of the sheet metal chassis, working from bottom to top.

[0003] like Figure 1 An existing radiator bracket is shown, comprising an upper vertical plate 101 and two horizontal plates of different heights, namely horizontal plate one 102 and horizontal plate two 103 (each 30mm high). The vertical plate 101 has a round hole 104 for fixing the radiator, the horizontal plate one 102 has a hexagonal fixing hole 105 for connecting to the sheet metal housing of a welding machine, and the horizontal plate two 103 holds the radiator.

[0004] It's clear that existing radiator brackets have a fixed height and only one installation height. Due to the heavy weight and susceptibility to deformation of radiators, the brackets must be manually installed onto the sheet metal. Specifically, the radiator brackets located at the bottom of the radiator require tightening the screws from the bottom of the sheet metal chassis upwards; while the radiator brackets located at the top of the radiator require tightening the screws from the top of the sheet metal chassis downwards. Installing the radiator brackets at the bottom is time-consuming and labor-intensive because it requires tightening the screws from the bottom up and tilting the welding machine base plate for manual installation. Utility Model Content

[0008] Preferably, the first vertical mounting hole is a hole for placing a round-headed bolt, and the second vertical mounting hole is a hole for placing a hexagonal nut.

[0009] Preferably, the first vertical mounting hole penetrates downward through the bracket base via the first mounting plane, and the second vertical mounting hole penetrates downward through the bracket base via the third mounting plane or the position adjacent to the third mounting plane and the second mounting plane.

[0010] Preferably, the bracket base and the vertical mounting plate are integrally injection molded.

[0011] Preferably, the bottom surface of the bracket base is a plane; wherein the distance between the first mounting plane and the bottom surface of the bracket base is 15mm, and the distance between the second mounting plane and the bottom surface of the bracket base is 25mm.

[0012] Furthermore, based on the aforementioned radiator bracket, this utility model further proposes an installation structure to realize the assembly between the radiator and the radiator bracket, the technical solution of which is as follows: An installation structure includes a radiator and a radiator bracket; at least two radiator brackets are provided at the bottom of the radiator and at least one radiator bracket is provided at the top of the radiator; the radiator bracket adopts the aforementioned radiator bracket.

[0013] The radiator bracket located at the bottom of the radiator has its first mounting plane / second mounting plane in contact with the bottom plane of the radiator, and the upper part of the vertical mounting plate in the radiator bracket is attached to and fastened to the side surface of the radiator. The radiator bracket located at the top of the radiator has its first mounting plane / second mounting plane in contact with the top plane of the radiator, and the upper part of the vertical mounting plate in the radiator bracket is attached to and fastened to the side surface of the radiator.

[0014] Furthermore, based on the aforementioned installation structure, this utility model further proposes an inverter welding machine to achieve the assembly between the radiator and radiator bracket mounting structure and the sheet metal of the inverter welding machine. The technical solution is as follows: An inverter welding machine includes a chassis, a heat sink and a heat sink bracket mounting structure; wherein the chassis includes a top sheet metal and a bottom sheet metal that are respectively connected to the heat sink and the heat sink bracket mounting structure at the top and bottom. The radiator and radiator bracket mounting structure adopts the above-mentioned mounting structure.

[0015] Preferably, sheet metal mounting holes are provided at the mounting positions of the radiator bracket on the top or bottom sheet metal; wherein the sheet metal mounting holes are aligned vertically with the first vertical mounting holes / second vertical mounting holes of the radiator bracket.

[0016] This utility model has the following advantages: As described above, this utility model relates to a radiator bracket, a mounting structure, and an inverter welding machine. The radiator bracket is designed with two mounting planes at different heights: a first mounting plane and a second mounting plane.

When the second vertical mounting hole is aligned with the sheet metal mounting hole on the top sheet metal of the inverter welding machine, and the first vertical mounting hole is aligned with the sheet metal mounting hole on the bottom sheet metal (with nuts pre-welded to the bottom sheet metal mounting hole), the radiator bracket can be easily fixed to the top and bottom sheet metal using hexagonal bolts and round-head bolts respectively. All installations are done from top to bottom, saving time and effort. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1 like Figures 2 to 5 As shown in the figure, this embodiment describes a heat sink bracket, which includes a bracket base 1 and a vertical mounting plate 2; the vertical mounting plate 2 is disposed in the middle of the bracket base 1 and divides the bracket base into two sides.

[0019] Define two sides of the support base 1, namely the first side 3 and the second side 4, the first side 3 being, for example, Figure 2 The right side shown in the image has a second side 4 opposite to the first side 3. Figure 2 The left side shown in the image.

[0020] Of course, the left and right sides are only for the convenience of explaining this utility model. In actual use, the direction may be the same as the direction defined above, or it may be different. This does not constitute a limitation on this utility model.

[0021] The first side 3 of the bracket base 1 is provided with a first mounting plane 5, and the second side 4 is provided with a second mounting plane 6; the first mounting plane 5 has a first height, and the second mounting plane 6 has a second height different from the first mounting plane.

[0022] In this embodiment, the height of the first mounting plane 5 is, for example, lower than the height of the second mounting plane 6; specifically, the heights of the first mounting plane 5 and the second mounting plane 6 are both relative to the bottom surface of the bracket base 1.

[0023] The bottom surface of the bracket base 1 is a plane. The vertical distance from the bottom surface of the bracket base 1 upward to the first mounting plane 5 is the height of the first mounting plane 5. The height of the second mounting plane 6 is the same, and will not be described again here.

[0024] The height of the first mounting plane 5 is, for example, 15mm, and the height of the second mounting plane 6 is, for example, 25mm.

[0025] By setting up two mounting planes with different heights, three different assembly heights can be formed when the different mounting planes of the radiator bracket contact the top and bottom surfaces of the radiator. Let's assume the height of the radiator is H.

[0026] When the first mounting plane 5 of the upper radiator bracket contacts the top surface of the radiator, and the second mounting plane 6 of the lower radiator bracket contacts the bottom surface of the radiator, the assembly height of the radiator and the radiator bracket is 15mm + H + 25mm.

[0027] When the second mounting plane 6 of the upper radiator bracket contacts the top surface of the radiator, and the first mounting plane 5 of the lower radiator bracket contacts the bottom surface of the radiator, the assembly height of the radiator and the radiator bracket is 25mm + H + 15mm.

[0028] When the first mounting plane 5 of the upper radiator bracket contacts the top surface of the radiator, and the first mounting plane 5 of the lower radiator bracket contacts the bottom surface of the radiator, the assembly height of the radiator and the radiator bracket is 15mm + H + 15mm.

[0029] When the second mounting plane 6 of the upper radiator bracket contacts the top surface of the radiator, and the second mounting plane 6 of the lower radiator bracket contacts the bottom surface of the radiator, the assembly height of the radiator and the radiator bracket is 25mm + H + 25mm.

[0030] Of course, in this embodiment, the height of the first mounting plane 5 is not necessarily lower than the height of the second mounting plane 6. For example, the height of the first mounting plane 5 can be higher than the height of the second mounting plane 6, and the above effect can be achieved in the same way.

[0031] Furthermore, the values ​​of the first mounting plane 5 and the second mounting plane 6 mentioned above are merely illustrative, and other values ​​may also be selected. The purpose of the examples here is only to facilitate the illustration of this utility model and does not constitute a specific limitation on this utility model.

[0032] The vertical mounting plate 2 is higher than the first mounting plane 5 and the second mounting plane 6. A horizontal mounting hole 7 is provided on the upper part of the vertical mounting plate 2, and its height is higher than the first mounting plane 5 and the second mounting plane 6.

[0033] The horizontal mounting hole 7 allows for the fixation of the side of the vertical mounting plate 2 and the side of the heat sink after they are attached together.

[0034] The first side portion 3 and the second side portion 4 are respectively provided with a first vertical mounting hole 8 and a second vertical mounting hole 9; wherein the first vertical mounting hole 8 and the second vertical mounting hole 9 both penetrate the corresponding positions of the bracket base 1 vertically.

[0035] The connection between the radiator bracket and the top and bottom sheet metal of the inverter welding machine can be achieved through the first vertical mounting hole 8 and the second vertical mounting hole 9, which will be described in detail in the following embodiment 3.

[0036] like Figure 2 and Figure 3 As shown, a third mounting plane 10 is also provided on the second side 4, which is lower than the second mounting plane 6. The second mounting plane 6 is closer to the vertical mounting plate 2 than the third mounting plane 10.

[0037] The top surfaces of the third mounting plane 10, the second mounting plane 6, and the vertical mounting plate 2 form a stepped platform structure that rises sequentially, such as... Figures 2 to 5 As shown, the above three elements form three platforms of a stepped platform structure.

[0038] The first vertical mounting hole 8 penetrates downward through the first mounting plane 5 to the bracket base 1, and the second vertical mounting hole 9 penetrates downward through the bracket base 1 at the adjacent position of the third mounting plane 10 and the second mounting plane 6. Figure 2 and 3 As shown.

[0039] Of course, the second vertical mounting hole 9 can also simply pass through the bracket base 1 downwards via the third mounting plane 10.

[0040] In this embodiment, the first vertical mounting hole 8 is designed, for example, as a hole for placing a round-headed bolt. Figure 3 As shown, this allows for easy insertion of round-headed bolts into the bolt placement hole, thereby securing the radiator bracket to the top / bottom sheet metal.

[0041] In this embodiment, the second vertical mounting hole 9 is designed, for example, as a hole for placing a hexagonal nut. Figure 3 As shown, it is used to place nuts. When fixing, the radiator bracket is fixed to the top / bottom sheet metal by the cooperation of bolts and nuts.

[0042] Of course, the specific structures of the first vertical mounting hole 8 and the second vertical mounting hole 9 are just examples. The first vertical mounting hole 8 can also be designed as a hexagonal nut placement hole, and the second vertical mounting hole 9 can be designed as a round head bolt placement hole.

[0043] Of course, the first vertical mounting hole 8 and the second vertical mounting hole 9 can also be designed to have the same structural form.

[0044] In this embodiment, the bracket base 1 and the vertical mounting plate 2 are formed by integral injection molding (material such as CCP PBT4830-NCB). This injection molding method makes the processing of the radiator bracket more convenient.

[0045] Example 2 This embodiment 2 describes an installation structure, which includes a radiator 11 and a radiator bracket 12; at least two radiator brackets 12 are provided at the bottom of the radiator 11 and at least one radiator bracket is provided at the top of the radiator 11.

[0046] The radiator bracket 12 is the radiator bracket described in Embodiment 1 above.

[0047] Taking the example of installing two radiator brackets 12 at the bottom of the radiator 11 and one radiator bracket 11 at the top.

[0048] like Figures 6 to 8 A first mounting structure for the radiator 11 and the radiator bracket 12 is shown, in which the radiator bracket 12 at the bottom is placed upright and the radiator bracket 12 at the top is placed upside down.

[0049] The two bottom radiator brackets 12 are aligned with the two sides of the bottom of the radiator 11, and the top radiator bracket 12 is aligned with the middle of the top of the radiator 11 to ensure that the radiator 11 is firmly fixed.

[0050] The radiator bracket 12 located at the bottom of the radiator has its second mounting plane 6 in contact with the bottom plane of the radiator 11, and the upper part of the vertical mounting plate 2 in the radiator bracket is attached to and fastened to the side surface of the radiator 11.

[0051] Specifically, the vertical mounting plate 2 is fastened to the radiator 11 by bolts passing through the horizontal mounting hole 7.

[0052] The radiator bracket 12 located at the top of the radiator has its first mounting plane 5 in contact with the top plane of the radiator 11, and the upper part of the vertical mounting plate 2 in the radiator bracket is attached to and fastened to the side surface of the radiator 11.

[0053] In the first mounting structure, the radiator bracket 12 located at the bottom of the radiator is connected to the top sheet metal of the inverter welding machine through the second vertical mounting hole 9, and to the bottom sheet metal of the inverter welding machine through the first vertical mounting hole 8.

[0054] As mentioned in Embodiment 1 above, the second vertical mounting hole 9 can be designed as a hexagonal nut placement hole.

[0055] Therefore, when installing with the top sheet metal, place the hexagonal nut in the hexagonal nut placement hole, and then pass the bolt through the sheet metal mounting hole and the second vertical mounting hole 9 of the top sheet metal in sequence from the top, and then connect it with the hexagonal nut to achieve fastening.

[0056] Similarly, as mentioned in Embodiment 1 above, the first vertical mounting hole 8 can be designed as a hole for placing round-headed bolts.

[0057] Therefore, when installing with the bottom sheet metal, a nut is spot-welded to the sheet metal mounting hole of the bottom sheet metal beforehand, and then the round head bolt is inserted into the first vertical mounting hole 8. The round head bolt is tightened with the nut from top to bottom to fix it to the bottom sheet metal.

[0058] It is easy to see from the first installation structure that both the installation of the radiator bracket 12 to the top sheet metal and the installation of the radiator bracket 12 to the bottom sheet metal are done from top to bottom, which is simple, convenient and saves time and effort.

[0059] In the first installation structure, the overall height of the radiator and radiator bracket 11 after assembly is 25mm + H + 15mm.

[0060] Of course, in this embodiment, the mounting structure between the heat sink 11 and the heat sink bracket 12 is not limited to the first type described above. For example, the second mounting structure described below can also be used. Figure 9 As shown.

[0061] In the second mounting structure, the first mounting plane 5 of the bottom radiator bracket 12 contacts the bottom surface of the radiator 11, and the second mounting plane 6 of the top radiator bracket 12 contacts the top surface of the radiator 11.

[0062] In the second installation structure, the overall height of the radiator and radiator bracket 11 after assembly is 15mm + H + 25mm.

[0063] Of course, in this embodiment, the mounting structure between the heat sink 11 and the heat sink bracket 12 is not limited to the first and second types described above. For example, the third type of mounting structure described below can also be used. Figure 10 As shown.

[0064] In the third mounting structure, the first mounting plane 5 of the bottom radiator bracket 12 contacts the bottom surface of the radiator 11, and the first mounting plane 5 of the top radiator bracket 12 contacts the top surface of the radiator 11.

[0065] In the third installation structure, the overall height of the radiator and radiator bracket 11 after assembly is 15mm + H + 15mm.

[0066] Of course, in this embodiment, the mounting structure between the heat sink 11 and the heat sink bracket 12 is not limited to the first, second, and third types described above. For example, the fourth mounting structure described below can also be used. Figure 11 As shown.

[0067] In the fourth mounting structure, the second mounting plane 6 of the bottom radiator bracket 12 contacts the bottom surface of the radiator 11, and the second mounting plane 6 of the top radiator bracket 12 contacts the top surface of the radiator 11.

[0068] In the fourth installation structure, the overall height of the radiator and radiator bracket 11 after assembly is 25mm + H + 25mm.

[0069] As can be seen, this embodiment can achieve various combinations of heights to adapt to flexible chassis height designs.

[0070] The installation structure of this embodiment can achieve universal compatibility with radiator brackets of different heights.

[0071] The original radiator bracket was designed with a height of only 30mm. The combined height of radiator 11 and radiator bracket 12 is 30mm + 30mm + H. This height is too high for the newly designed welding machine chassis and a new bracket must be designed.

[0072] Since semiconductors are mounted on the heatsink 11, the height (H) cannot be changed. Therefore, this invention designs the heatsink bracket 12 to have two heights, such as 15mm and 25mm. Based on the newly designed height of the chassis, three heights can be used: I. 15mm+25mm+H; II. 15mm+15mm+H; III. 25mm+25mm+H.

[0073] When a smaller welding machine chassis height is required, different mounting structures can be flexibly selected without redesigning.

[0074] Example 3 This embodiment 3 describes an inverter welding machine, which includes a chassis 15 and a heat sink and a heat sink bracket mounting structure; wherein the chassis includes a top sheet metal 13 and a bottom sheet metal 14 that are respectively connected to the heat sink and the heat sink bracket mounting structure at the top and bottom.

[0075] The radiator and radiator bracket mounting structure adopts the mounting structure in Embodiment 2 above.

[0076] Sheet metal mounting holes are provided at the mounting positions of the top sheet metal 13 or bottom sheet metal 14 corresponding to the radiator bracket 12; wherein the sheet metal mounting holes are aligned vertically with the first vertical mounting hole 8 / second vertical mounting hole 9 of the radiator bracket 12.

[0077] Taking the first installation structure in Embodiment 2 as an example, such as Figure 12 and Figure 13 As shown: A sheet metal mounting hole is provided on the top sheet metal 13 at the position corresponding to the second vertical mounting hole 9. The bolt is passed through the sheet metal mounting hole and the second vertical mounting hole 9 from top to bottom, and then connected to the hexagonal nut of the second vertical mounting hole 9 to achieve fastening.

[0078] Sheet metal mounting holes are set at the positions of the bottom sheet metal 14 corresponding to the first vertical mounting holes 8, and nuts are pre-installed at each sheet metal mounting hole by spot welding. Then, round head bolts are inserted into the first vertical mounting holes 8 to achieve installation from top to bottom.

[0079] This top-down assembly method is more convenient for workers to install manually compared to the traditional method, and it is conducive to achieving automated installation.

[0080] Of course, the second, third and fourth installation structures in the above embodiment 2 can also be installed separately with the top sheet metal 13 and bottom sheet metal 14 in the chassis 15, which will not be described in detail here.

[0081] The radiator bracket described in this utility model allows for flexible installation of the radiator 11 and the radiator bracket 12, and the overall height design of the assembled installation structure is flexible, thus adapting well to the flexible design of the chassis height.

[0082] Of course, the above description is only a preferred embodiment of the present utility model. The present utility model is not limited to the above-described embodiments. It should be noted that any equivalent substitutions or obvious modifications made by those skilled in the art under the guidance of this specification fall within the scope of this specification and should be protected by the present utility model.
