Description

Technical Field

[0001] This utility model relates to the field of liquid cooling joint production technology, and in particular to a flip-type push-pull pressing test fixture for liquid cooling joints. Background Technology

[0002] Liquid cooling connectors are core connectors used in liquid cooling systems to connect different liquid cooling components such as cold plates and radiators. During the production process of liquid cooling connectors, a series of tests need to be performed on the semi-finished products to determine whether they meet quality requirements. These tests include helium testing and high-pressure nitrogen testing. Helium testing involves filling the semi-finished connector with helium gas and then using a helium mass spectrometer leak detector to detect whether helium gas will leak out. High-pressure nitrogen testing involves filling the semi-finished connector with high-pressure nitrogen gas, observing the pressure gauge reading, and determining whether there is a leak. At the same time, the semi-finished connector is also checked for deformation or other phenomena.

[0003] During the testing process, liquid-cooled connector semi-finished products require accurate fixation and positioning using testing fixtures, which also provide test gas connection interfaces. These semi-finished products have multiple interfaces, such as bottom and side interfaces. Currently, some conventional testing fixtures use screw-locking structures to fix and position the semi-finished products, and plugs to seal the interfaces. Screw-locking clamping operations are cumbersome and inconvenient, and some conventional single testing fixtures cannot clamp multiple semi-finished products simultaneously, resulting in low testing efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a flip-type push-pull pressing test fixture that can clamp multiple liquid-cooled connector products in one test, with high testing efficiency, convenient and quick clamping, and short pressing and fastening time.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A flip-top push-pull pressing test fixture includes a base plate, multiple product positioning posts, a flip-top pressure plate, a push-pull pressure plate, and multiple push-pull quick clamps. The multiple product positioning posts are arranged in a matrix and mounted on the base plate, with each post matching the bottom interface of a liquid-cooled connector product. Multiple hinge seats are spaced along the length of one side of the product positioning posts on the base plate. Multiple rotating connecting rods corresponding to the hinge seats are spaced along one edge of the flip-top pressure plate, and these rotating connecting rods are hinged to the hinge seats. The flip-top pressure plate, after flipping, is used to press against the top of the liquid-cooled connector product. The push-pull pressure plate is slidably mounted on the base plate and located on the other side of the product positioning posts. Multiple side connectors matching the side interfaces of the liquid-cooled connector product are spaced along the side of the push-pull pressure plate closest to the product positioning posts. Multiple push-pull quick clamps are spaced on the base and connected to the push-pull pressure plate, used to move the push-pull pressure plate towards or away from the product positioning posts.

[0007] In some embodiments, the top of the product positioning post is conical, the bottom of the product positioning post is provided with a first annular step, and a first sealing gasket is fitted on the product positioning post, with the first sealing gasket located above the first annular step.

[0008] In some embodiments, the head of the side connector is also tapered, the end of the side connector is provided with a second annular step, and a second sealing gasket is fitted on the side connector, with the second sealing gasket located at the front end of the second annular step.

[0009] Compared with the prior art, this utility model achieves at least the following beneficial effects:

[0010] The liquid cooling connector is placed on the product positioning post, which inserts and seals the bottom interface of the liquid cooling connector. The flip-top pressure plate is rotated to press against the top of the liquid cooling connector. The handle of the push-pull quick clamp is pulled, which moves the push-pull pressure plate toward the multiple product positioning posts and presses it against the side of the liquid cooling connector. The side connector is inserted into the side interface of the liquid cooling connector, facilitating the filling of the liquid cooling connector with test gas for relevant tests. Compared with the conventional clamping method using screws or plugs, this invention is more convenient and faster to clamp, with a shorter clamping and locking time. This invention allows multiple liquid cooling connectors to be placed at a single station in a single test, resulting in high testing efficiency. Attached Figure Description

[0019] like Figures 1-4 As shown in the embodiment of this application, the flip-top push-pull pressing test fixture can clamp the semi-finished product 30 of the liquid cooling connector product 30 to facilitate helium testing, high-pressure nitrogen testing and other tests on the semi-finished product 30 of the liquid cooling connector product 30. The flip-top push-pull pressing test fixture includes a base plate 1, multiple product positioning posts 2, a flip-top pressure plate 3, a push-pull pressure plate 4 and multiple push-pull quick clamps 5.

[0020] In this embodiment, multiple product positioning posts 2 are arranged in a matrix and installed on the base plate 1. Each product positioning post 2 matches the bottom interface of the liquid cooling connector product 30. In this embodiment, multiple product positioning posts 2 are arranged in a matrix of 2 rows and 8 columns. Two product positioning posts 2 in each column are used as a group to position one liquid cooling connector product 30. The liquid cooling connector product 30 is placed on the product positioning post 2, and the product positioning post 2 is inserted into and seals the bottom interface of the liquid cooling connector product 30. Multiple hinge seats 6 are installed at intervals along the length direction on one side of multiple product positioning posts 2 on the base plate 1. Multiple rotating connecting rods 7 corresponding to the hinge seats 6 are installed at intervals on one side edge of the flip-top pressure plate 3. The rotating connecting rods 7 are hinged to the hinge seats 6. Specifically, a horizontal shaft is installed on the hinge seat 6, and the rotating connecting rods 7 are rotatably connected to the horizontal shaft, so that the flip-top pressure plate 3 can rotate and flip on the hinge seats 6. In this embodiment, the rotation angle range of the flip-top pressure plate 3 is 0-130 degrees. When the flip-top pressure plate 3 is flipped up, it is convenient for loading materials. When the flip-top pressure plate 3 is flipped down, it is used to press on the top of the liquid cooling connector product 30. A push-pull pressure plate 4 is slidably mounted on the base plate 1, and is located on the other side of multiple product positioning posts 2. Multiple side connectors 41, matching the side interfaces of the liquid cooling connector product 30, are spaced apart on the side of the push-pull pressure plate 4 closest to the product positioning posts 2. The side connectors 41 are used to insert into the side interfaces of the liquid cooling connector product 30 and communicate with the inner cavity of the liquid cooling connector product 30. Multiple push-pull quick clamps 5 are spaced apart and mounted on the base, and are connected to the push-pull pressure plate 4. They are used to move the push-pull pressure plate 4 towards or away from the multiple product positioning posts 2, thereby realizing the pressing and releasing action of the push-pull pressure plate 4 on the liquid cooling connector product 30.

[0021] Specifically, the top of the product positioning post 2 is conical, which facilitates insertion into the bottom interface of the liquid cooling connector product 30. The bottom of the product positioning post 2 is provided with a first annular step 21, and a first sealing gasket 22 is fitted on the product positioning post 2. The first sealing gasket 22 is located above the first annular step 21. The bottom interface of the liquid cooling connector product 30 is sealed by setting the first sealing gasket 22.

[0022] The head of the side connector 41 is also tapered, which facilitates insertion into the side interface of the liquid cooling connector product 30. The end of the side connector 41 is provided with a second annular step 411, and a second sealing gasket 412 is fitted on the side connector 41. The second sealing gasket 412 is located at the front end of the second annular step 411. The sealing performance of the side connector 41 is ensured when it is connected by setting the second sealing gasket 412.

[0023] The push-pull pressure plate 4 has a gas channel along its length. The side wall of the push-pull pressure plate 4 is equipped with a quick-connect connector 42. The quick-connect connector 42 and multiple side connectors 41 are connected to the gas channel. It can be connected to an external gas source through the quick-connect connector 42 to fill with gases such as helium and nitrogen, and to conduct relevant tests on the liquid cooling connector product 30.

[0024] The working surface of the flip-top pressure plate 3 is fixedly connected to a POM plastic pad 31. The pad 31 is in contact with the product to prevent damage to the product.

[0025] Multiple mounting seats 8 are fixedly connected to the base plate 1. The mounting seats 8 are horizontally provided with mounting through holes 81, and the mounting holes are provided with internal threads. In this embodiment, the push-pull quick clamp 5 includes a fixed cylinder 51, a connecting shaft 52, a Y-shaped connecting seat 53, a handle 54, a first connecting plate 55, and a second connecting plate 56. The fixed cylinder 51 is provided with external threads and is threadedly connected to the mounting through holes 81 through the external threads. One end of the connecting shaft 52 moves through the fixed cylinder 51 and the mounting through holes 81 and is connected to the push-pull pressure plate 4. The Y-shaped connecting seat 53 is hinged to the other end of the connecting shaft 52. The handle 54 is fixedly connected to the Y-shaped connecting seat 53. The first connecting plate 55 and the second connecting plate 56 are located on both sides of the fixed cylinder 51, and a horizontal plate 9 is fixedly connected between the first connecting plate 55 and the second connecting plate 56. One end of the first connecting plate 55 and one end of the second connecting plate 56 are hinged to both sides of the fixed cylinder 51, and the other end of the first connecting plate 55 and the other end of the second connecting plate 56 are hinged to both sides of the Y-shaped connecting seat 53. When the handle 54 is pulled, the connecting shaft 52 can be driven to reciprocate linearly along its own axis through the Y-type connecting seat 53. For example, when the handle 54 is pulled, the connecting shaft 52 can be pulled outward through the Y-type connecting seat 53, causing the connecting shaft 52 to move to the right. The connecting shaft 52 drives the push-pull pressure plate 4 to move away from the multiple product positioning posts 2. Conversely, when the handle 54 is pushed, the connecting shaft 52 drives the push-pull pressure plate 4 to move toward the multiple product positioning posts 2. The push-pull pressure plate 4 achieves the pressing of the liquid cooling connector product 30.

[0026] Optionally, a limiting plate 521 is provided on one end of the connecting shaft 52 of one of the push-pull quick clamps 5 near the push-pull pressure plate 4. The push-pull pressure plate 4 is provided with a T-slot 43 that mates with the connecting shaft 52 and the limiting plate 521, allowing the connecting shaft 52 to pull or push the push-pull pressure plate 4. After the liquid cooling connector product 30 is placed on the product positioning post 2, the connecting shafts 52 of the remaining push-pull quick clamps 5 are used to press against the push-pull pressure plate 4 to ensure that the push-pull pressure plate 4 presses the liquid cooling connector product 30 tightly. The push-pull pressure plate 4 is provided with grooves that match the connecting shafts 52 of the remaining push-pull quick clamps 5, allowing the connecting shafts 52 of the remaining push-pull quick clamps 5 to be inserted into the corresponding grooves.

[0027] Multiple limiting blocks 10 are installed on the base plate 1 between the product positioning post 2 and the push-pull pressure plate 4. The limiting blocks 10 press against the push-pull pressure plate 4 to limit the push-pull plate.

[0028] The bottom of the base plate 1 has four vertical support feet 20 made of urethane rubber installed at the four corners.

[0029] The working principle of this utility model is as follows:

[0030] First, place the liquid cooling connector product 30 on the product positioning post 2. The product positioning post 2 is inserted and seals the bottom interface of the liquid cooling connector product 30. Next, rotate the flip-top pressure plate 3 to press it onto the top of the liquid cooling connector product 30. Then, pull the handle 54 of the push-pull quick clamp 5. Through the connecting shaft 52, the push-pull pressure plate 4 moves towards the multiple product positioning posts 2. The push-pull pressure plate 4 presses tightly against the side of the liquid cooling connector product 30. The side connector 41 is inserted into the side interface of the liquid cooling connector product 30. Test gas is injected through the quick-connect connector 42 of the push-pull pressure plate 4 to perform relevant tests on the liquid cooling connector product 30. Compared with the conventional clamping method of locking screws or plugs, this utility model is more convenient and faster to clamp, and the clamping and locking time is shorter. This utility model can place multiple liquid cooling connector products 30 at a single station in one test, resulting in high testing efficiency.

[0031] It should be understood that all the above embodiments are exemplary and not restrictive. Any modifications, equivalent changes and alterations made by those skilled in the art to the specific embodiments described above under the concept of this utility model shall still fall within the scope of the technical solution of this utility model.
