Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plate welding technology, and in particular to a tooling fixture for welding liquid cooling plates. Background Technology

[0002] Fixtures for welding liquid-cooled plates are auxiliary devices specifically designed for this purpose. They are used to fix, position, and clamp liquid-cooled plates and their components, ensuring welding accuracy and stability. Types include manual, pneumatic / hydraulic, electromagnetic, and specialized welding fixtures, each with its own characteristics. Design considerations include strength, clamping force, operational flexibility, and manufacturing precision. These fixtures are widely used in new energy vehicles, energy storage systems, 5G base stations and data centers, aerospace, and other fields to ensure reliable welding and heat dissipation performance of liquid-cooled plates. In the future, fixtures will develop towards intelligence, modularity, environmental friendliness, and high precision, integrating sensors and control systems to improve production efficiency and welding quality.

[0003] Due to their high plasticity, existing liquid cooling plates are used in various fields. Different fields have different requirements for the shape and structure of liquid cooling plates, which necessitates welding. During the welding process, liquid cooling plates are generally clamped using tooling fixtures. The commonly used method in the market is to use a machining platform with multiple fixing holes evenly spaced on its surface. The fixture is placed on the tooling platform and then fixed by bolts inserted into the fixing holes of the machining platform. However, because the holes inside the machining platform are evenly spaced, the fixture can only be placed at 90° horizontally and vertically during the clamping process. The flexibility of the fixture is limited, resulting in reduced clamping stability of the liquid cooling plate and inconvenience in use. Utility Model Content

[0004] Therefore, it is necessary to provide a tooling fixture for welding liquid cooling plates, which addresses the problem that the equally spaced holes inside the processing platform cause the fixture to be placed at 90° horizontally and vertically during the clamping process, limiting the flexibility of the fixture and reducing the clamping stability of the liquid cooling plate, resulting in inconvenience in use.

[0005] A fixture for welding liquid-cooled plates includes: a liquid-cooled plate support assembly, the liquid-cooled plate support assembly including a support platform and limiting blocks, the limiting blocks being provided in multiples, the multiple limiting blocks being equidistantly disposed on the surface of the support platform, and the surface of the support platform being provided with multiple limiting grooves at equal intervals;

[0006] A first limiting plate is disposed on the support platform and located above the support platform. A second limiting plate is disposed above the support platform. A fixing plate is fixedly connected above the second limiting plate. A tooling fixture body is fixedly connected above the fixing plate.

[0007] In one embodiment, a limiting slider is fixedly connected below the first limiting disk, and the limiting slider slides below the plurality of limiting blocks.

[0008] In one embodiment, protrusions are provided above the first limiting plate and below the second limiting plate, and the upper part of the first limiting plate and the lower part of the second limiting plate are engaged with each other through the protrusions.

[0009] In one embodiment, the first limiting plate, the second limiting plate, and the limiting groove are on the same axis, and a column is fixedly connected to the axis of the second limiting plate, with the lower end of the column extending into the interior of the limiting groove.

[0010] In one embodiment, the limiting groove is a through groove, and the upper part of the limiting groove extends outward along the surface of the support platform.

[0011] In one embodiment, the column slides along the inner wall of the first limiting plate and the limiting slider, and the second limiting plate rotates above the first limiting plate.

[0012] In one embodiment, an annular groove is formed on the surface of the column, and a fixing rod is threaded into the inside of the limiting slider. One end of the fixing rod is inserted into the limiting slider and the annular groove and fits against the outer wall of the column.

[0013] In one embodiment, the upper part of the second limiting plate is attached to the lower part of the fixing plate, and the second limiting plate, the fixing plate and the tooling fixture body are fixed together by bolts. Beneficial effects

[0014] 1. When clamping the liquid cooling plate, place the liquid cooling plate above the liquid cooling plate support assembly. Multiple limiting blocks, equidistantly supported above the support platform, support the bottom of the liquid cooling plate. The limiting blocks and limiting grooves are equidistantly arranged, with four closest limiting blocks forming a group. The limiting groove is located at the diagonal of each group of limiting blocks, and multiple limiting blocks can be combined multiple times. The upper surface of the limiting blocks is much larger than the surface area of ​​the gaps between multiple limiting blocks, which greatly increases the bearing capacity and stability of the limiting blocks for the liquid cooling plate. The first limiting plate supports the second limiting plate, and the second limiting plate supports the fixing plate and the fixture body. By changing the rotation angle of the second limiting plate, the angle of the fixture body changes, which greatly increases the flexibility and clamping stability of the fixture body in clamping the liquid cooling plate.

[0015] 2. Multiple limiting blocks have a top-wide, bottom-narrow structure, forming multiple sets of sliding grooves. The limiting slider slides horizontally or vertically within these grooves. A first limiting plate is fixed above the limiting slider with bolts. A second limiting plate is placed on top of the first limiting plate. The first and second limiting plates are in contact with the outer walls of the multiple limiting blocks, increasing the stability of the second limiting plate's support for the fixing plate. The first and second limiting plates are engaged by bosses. After the second limiting plate is engaged with the first limiting plate below, the second limiting plate stops rotating. The second limiting plate can be picked up and rotated. Through the interlocking of multiple sets of bosses, the second limiting plate can be fixed at multiple angles, greatly increasing the flexibility of clamping the fixing plate and the tooling fixture body.

[0028] The following is combined Figures 1-4 This invention describes a tooling fixture for welding liquid-cooled plates.

[0029] In one embodiment, a tooling fixture for welding a liquid cooling plate includes: a liquid cooling plate support assembly 100 and a first limiting plate 200. The liquid cooling plate support assembly 100 includes a support platform 101 and limiting blocks 102. Multiple limiting blocks 102 are provided and are equidistantly arranged on the surface of the support platform 101. Multiple limiting grooves 103 are equidistantly opened on the surface of the support platform 101. The first limiting plate 200 is disposed on the support platform 101 and located above the support platform 101. A second limiting plate 300 is provided above the support platform 101. A fixing plate 400 is fixedly connected above the second limiting plate 300. A tooling fixture body 500 is fixedly connected above the fixing plate 400.

[0030] In this embodiment, when the liquid cooling plate needs to be clamped, the liquid cooling plate is placed above the liquid cooling plate support assembly 100. Multiple limiting blocks 102, which are equidistantly supported above the support platform 101, support the bottom of the liquid cooling plate. The limiting blocks 102 and the limiting grooves 103 are arranged at equal intervals. Every four closest limiting blocks 102 form a group. The limiting grooves 103 are located at the diagonal of each group of limiting blocks 102. Multiple limiting blocks 102 can be combined multiple times. The upper surface of the limiting blocks 102 is much larger than the surface area of ​​the gap between multiple limiting blocks 102, which greatly increases the bearing capacity and stability of the limiting blocks 102 for the liquid cooling plate.

[0031] The first limiting plate 200 supports the second limiting plate 300 above, and the second limiting plate 300 supports the fixing plate 400 and the tooling fixture body 500 above. By changing the rotation angle of the second limiting plate 300, the angle of the tooling fixture body 500 is changed, which greatly increases the flexibility and stability of the tooling fixture body 500 in clamping the liquid cooling plate.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a limiting slider 201 is fixedly connected to the lower part of the first limiting disk 200. The limiting slider 201 slides below multiple limiting blocks 102. Bosses are provided above the first limiting disk 200 and below the second limiting disk 300. The upper part of the first limiting disk 200 and the lower part of the second limiting disk 300 are engaged with each other through the bosses.

[0033] In this embodiment, the multiple limiting blocks 102 are all of the structure that is wider at the top and narrower at the bottom. The multiple limiting blocks 102 form multiple sets of sliding grooves. The limiting slider 201 slides horizontally or vertically inside the multiple sets of sliding grooves. The first limiting plate 200 is fixed above the limiting slider 201 by bolts. The second limiting plate 300 is placed above the first limiting plate 200. The periphery of the first limiting plate 200 and the second limiting plate 300 will fit against the outer wall of the multiple limiting blocks 102, increasing the stability of the second limiting plate 300 supporting the fixing plate 400.

[0034] The first limiting plate 200 and the second limiting plate 300 are engaged by a boss. After the second limiting plate 300 is attached to the first limiting plate 200 below, the second limiting plate 300 stops rotating. The second limiting plate 300 can be picked up and rotated. Through the interlocking of multiple sets of bosses, the second limiting plate 300 can be fixed at multiple angles, which greatly increases the flexibility of the clamping of the fixing plate 400 and the tooling fixture body 500.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the first limiting plate 200, the second limiting plate 300 and the limiting groove 103 are on the same axis. A column 301 is fixedly connected to the axis of the second limiting plate 300. The lower end of the column 301 extends into the interior of the limiting groove 103. The limiting groove 103 is a through groove. The upper part of the limiting groove 103 extends outward along the surface of the support platform 101.

[0036] In this embodiment, the column 301 is located at the axis of the second limiting plate 300 and is integrally connected with the second limiting plate 300. The column 301 slides along the inner wall of the first limiting plate 200 and the limiting slider 201. When the upper part of the first limiting plate 200 and the lower part of the second limiting plate 300 are in contact, the lower end of the column 301 is inserted into the interior of the limiting groove 103. After the column 301 is inserted into the interior of the limiting groove 103, the column 301 will be horizontally engaged with the support platform 101, so that the second limiting plate 300 cannot move or rotate, and the tooling fixture body 500 above the second limiting plate 300 is fixed.

[0037] like Figure 1 , Figure 2 and Figure 4 As shown, the column 301 slides along the inner wall of the first limiting plate 200 and the limiting slider 201, and the second limiting plate 300 rotates above the first limiting plate 200. An annular groove 302 is provided on the surface of the column 301. A fixing rod 202 is threaded into the inside of the limiting slider 201. One end of the fixing rod 202 is inserted into the inside of the limiting slider 201 and the annular groove 302 and is in contact with the outer wall of the column 301.

[0038] In this embodiment, after the fixing rod 202 is threaded into the limiting slider 201, one end of the fixing rod 202 is a nut, which facilitates the rotation of the fixing rod 202. The other end of the fixing rod 202 is inserted into the annular groove 302 and fits against the annular groove 302, and limits the insertion direction of the column 301, so that the column 301 cannot slide up and down, thereby improving the tightness of the engagement between the second limiting plate 300 and the first limiting plate 200.

[0039] like Figure 1 and Figure 2As shown, the upper part of the second limiting plate 300 is attached to the lower part of the fixing plate 400, and the second limiting plate 300, the fixing plate 400 and the tooling fixture body 500 are fixed together by bolts.

[0040] In this embodiment, multiple bolts pass through the tooling fixture body 500 and the fixing plate 400 and are then threaded into the interior of the second limiting plate 300 for fixing the second limiting plate 300, the fixing plate 400 and the tooling fixture body 500. Multiple bolts are located on both sides of the tooling fixture body 500 and pass through the fixing plate 400 to be threadedly connected to the second limiting plate 300, thereby strengthening the stability of the connection between the second limiting plate 300 and the fixing plate 400.

[0041] Working principle:

[0042] The liquid cooling plate support assembly 100 consists of a support platform 101, multiple limiting blocks 102, and limiting grooves 103. The limiting grooves 103 are located at the diagonal of every four limiting blocks 102. The included angle formed by the multiple limiting blocks 102 limits the first limiting plate 200 and the second limiting plate 300. The limiting slider 201 is inserted from the side and slid to the top of the limiting groove 103. Then, the first limiting plate 200 is inserted between the multiple limiting blocks 102 and fixed to the limiting slider 201 with bolts, which increases the stability of the first limiting plate 200 during installation.

[0043] The second limiting plate 300 is inserted into the axis of the first limiting plate 200 via the column 301. After the second limiting plate 300 is engaged with the first limiting plate 200 below, a fixing rod 202 is inserted. The fixing rod 202 fixes the position of the column 301, locking the lifting and rotation of the second limiting plate 300. The upper part of the second limiting plate 300 supports the upper fixing plate 400 and the tooling fixture body 500. Multiple sets of tooling fixture bodies 500 clamp the liquid cooling plate at different angles and heights, increasing the clamping stability during the welding process of the liquid cooling plate.

[0044] It should be noted that the tooling fixture body 500 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs, and will not be elaborated here.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
