Description

Technical Field

[0001] The present invention relates to a clamping fixture, especially a detachable clamping fixture used for quickly fixing and testing a special-shaped quick connector in the technical field of testing equipment, which has a stable structure and the function of adjustable clamping to improve the testing efficiency and accuracy.

Prior Art

[0002] The present invention relates to a clamping fixture, especially a detachable clamping fixture used for quickly fixing and testing a special-shaped quick connector in the technical field of testing equipment, which has a stable structure and the function of adjustable clamping to improve the testing efficiency and accuracy.

[0003] With the increasing operating requirements of data centers or cloud computing centers, the requirements for the cooling system have become more stringent. When the servers and other high-value equipment in the data center are operating efficiently, they must be kept at a low temperature to prevent overheating, which makes the reliability of the cooling system a key factor in the operation of the data center. Once the cooling system fails, it may cause the equipment to overheat, which in turn may lead to the shutdown of the data center or equipment damage, causing huge financial losses to the enterprise.

[0004] Among them, water-cooled cooling systems have been widely used in data centers due to their more efficient heat dissipation performance. Such systems use working liquids to carry away heat, which helps to reduce operating costs and improve heat dissipation efficiency. However, if the parts in the water-cooled system, especially the pipelines and quick connectors, leak water, it may lead to catastrophic consequences such as short circuits, equipment damage or fires. Every part in the data center, especially the parts in the cooling system, needs to undergo strict reliability tests to ensure that it will not affect the operation of the system due to water leakage or other failures, and avoid causing interruptions in the operation of the data center and huge financial losses.

[0005] However, when the prior art conducts reliability tests on quick connectors, there are the following deficiencies: 1. It is impossible to stably fix the quick connector for testing: In order to be easy to hold the quick connector, the existing quick connectors are mainly cylindrical in shape, and there may be waists or grooves on their cylindrical shapes, but they are still arc-shaped. It is difficult for the existing clamping fixtures to clamp and fix them. For quick connectors with special shapes, especially those with tower-shaped interfaces, it is even more difficult for the existing clamping fixtures to clamp such quick connectors, thus affecting the accuracy and reliability of the test. 2. The parts are not convenient for assembly and replacement: The existing fixture designs are not flexible enough for parts that need to be frequently replaced or adjusted, and cannot be assembled and replaced simply, resulting in wasted time and increased operation difficulties during the test process.

[0006] These problems make existing technologies unable to effectively meet the high requirements for component reliability testing, posing a significant challenge to component reliability testing in data center operations. Therefore, the market needs a clamping fixture that provides higher stability and flexible adjustment to solve the testing problems of these specially shaped components, ensuring the reliability of each component in actual operation, further reducing the risk of data center downtime, and protecting enterprise assets. [Summary of the Invention]

[0007] Therefore, in order to effectively solve the above problems, the main objective of the present invention is to provide a detachable clamping fixture.

[0008] To achieve the above objectives, the clamping fixture provided by the present invention includes a base, at least two support members, and a clamping unit. The corresponding two sides of the base are respectively connected to one end of the two support members, and the corresponding two sides of the clamping unit are respectively connected to the other end of the two support members. The clamping unit includes a base, two clamping plates, and a cover plate. The base has a receiving groove with a first through hole. The two clamping plates are respectively arranged in the receiving groove with the notches of the clamping parts facing each other to jointly define the clamping opening corresponding to the first through hole. The cover plate is placed on the base and has a second through hole corresponding to the clamping opening. The first through hole, the clamping opening, and the second through hole together constitute a channel for accommodating a first test piece, and the first test piece located in the channel is clamped by the clamping parts of the two clamping plates.

[0009] In addition, the clamping unit also includes a fastening hole, which is provided on the side of the base where the two supports are not connected. A fastener is provided in the fastening hole for pushing the clamping plate to clamp the first test piece.

[0010] The clamping fixture of the present invention addresses the shortcomings of existing technologies by providing an effective solution: 1. Solving the problem of not being able to fix products for testing: The present invention uses clamping parts with V-shaped, U-shaped, or angled openings in the clamping plate for quick adjustment to clamp parts with special shapes (e.g., quick connectors with pagoda-shaped interfaces) to adapt to diverse part shapes and diameters, ensuring that parts do not wobble during testing and improving the accuracy and reliability of testing. 2. Solving the problem of inconvenient assembly and replacement of parts: The base, support, and clamping unit are designed to be detachable and replaceable, allowing for the replacement of bases with different through-hole diameters according to different sizes of quick connectors or the replacement of support parts according to hose length, thereby meeting the testing needs of quick connectors of various sizes. The modular design between the base, support, and clamping unit further simplifies the part replacement process and meets the needs of frequent testing.

[0011] Through the above design, the fixture of the present invention greatly improves the stability, flexibility and compatibility of the testing process, and fully meets the high standard requirements for component reliability testing.

Implementation Method

[0012] The above-mentioned objectives of the present invention and its structural and functional characteristics will be described with reference to the preferred embodiments shown in the accompanying drawings.

[0013] Referring to Figures 1, 2, and 5, which are respectively an exploded perspective view, a schematic diagram, and a schematic diagram of clamping a quick connector 50 with a pagoda-shaped end interface in the clamping fixture 1 of the present invention. The clamping fixture 1 includes a base 10, at least two support members 20, and a clamping unit 30. As shown, the base 10 and the clamping unit 30 are located in the middle of the two support members 20. The left and right sides of the base 10 are respectively connected to the lower ends of the two support members 20, while the left and right sides of the clamping unit 30 are respectively connected to the upper ends of the support members 20 to define the operating space 40. As shown in Figure 5, within the operating space 40, the tester can assemble the upper end of the hose 51, which is originally installed on the adapter 52 of the base 10, with the pagoda-shaped end interface of the quick connector 50 for subsequent testing.

[0014] The base 10 has a plurality of first locking holes 11 on its left and right sides, and the lower ends of the two support members 20 each have a plurality of second locking holes 21. The positions of these second locking holes 21 correspond to the positions of the first locking holes 11, and the base 10 can be firmly fixed to the lower ends of the two support members 20 by passing the first locking holes 11 and the second locking holes 21 through the first locking holes 11 and the second locking holes 21, providing stable structural support (as shown in Figure 5). The base 10 can be easily disassembled and replaced to accommodate adapters 52 of different sizes or through-hole diameters to meet various testing requirements.

[0015] The base 10 is provided with a third through hole 13, which connects the upper and lower sides of the base 10. The third through hole 13 has an upper end, an inner wall, and a lower end. The inner wall connects the upper and lower ends and has a threaded structure design. The adapter 52 can be screwed into the third through hole 13 by means of the threaded structure to ensure a stable connection between the adapter 52 and the base 10. The upper end of the third through hole 13 can be used to fix the adapter 52, and the lower end is used to connect the pressure medium testing equipment to seal the pressure medium flow circuit. The base 10 may also be further provided with multiple through machine connection holes (not shown) for fixing the base 10 to the pressure medium testing equipment (not shown), so that the clamping fixture 1 can be positioned on the pressure medium testing equipment and the pressure medium during testing can be stably transmitted. The position of the machine connection holes can be designed according to the requirements of the testing equipment to further improve the stability and accuracy during the testing process.

[0016] In addition, the upper ends of the two support members 20 are provided with a plurality of third locking holes 22, and the left and right sides of the clamping unit 30 are provided with a plurality of fourth locking holes 32. The positions of these third locking holes 22 correspond to the positions of the fourth locking holes 32 respectively. The clamping unit 30 is fixed to the upper ends of the two support members 20 by the second locking fastener 42 passing through the third locking holes 22 and the fourth locking holes 32.

[0017] Refer to Figures 3 and 4, which are respectively an exploded perspective view of the clamping unit 30 and a schematic diagram of the clamping plate 33 placed in the receiving groove 311, and refer to Figure 5 in conjunction. The clamping unit 30 mainly includes a base 31, two clamping plates 33, and a cover plate 34. The base 31 is the main support structure of the clamping unit 30. The base 31 is provided with a receiving groove 311, and the receiving groove 311 has a first through hole 312 inside. The receiving groove 311 is a space to accommodate the two clamping plates 33, so that the clamping plates 33 can be stably placed on it and form a clamping opening 35 with a clamping angle. The clamping opening 35 is used to clamp quick connectors of various shapes. A plurality of fourth locking holes 32 are provided on opposite sides of the base 31 of the clamping unit 30, for example, the left and right sides. The positions of these fourth locking holes 32 correspond to the third locking holes 22 on the two support members 20. The base 31 is fixed to the support member 20 by the second locking fastener 42. The base 31 has a fastening mechanism on the side without the fourth locking hole 32, such as the fastening hole 36 shown in the figure. The space of the receiving groove 311 is slightly larger than the space occupied by the two clamping plates 33 in the receiving groove 311, providing an adjustable operating space. The fastening hole 36 is equipped with a fastener 44 to adjust the tightness of the clamping quick connector 50.

[0018] Both clamping plates 33 are provided with clamping portions 331, which can adopt a V-shaped or U-shaped structure to clamp quick connectors of different shapes. The clamping plates 33 are placed in the receiving groove 311 of the base 31 with the clamping portions 331 facing each other to jointly define the clamping opening 35. The clamping opening 35 corresponds to the first through hole 312 of the base 31. The diameter of the clamping opening 35 is smaller than that of the first through hole 312 of the base 31. The clamping plates 33 are made of high-strength metal materials (e.g., steel or iron) to ensure the durability of the clamping unit 30. The fastener 44 passes through the fastening hole 36 and abuts against one of the clamping plates 33. The tester can adjust the fastener 44 to push the clamping plate 33, thereby adjusting the position of the clamping plate 33 in the receiving groove 311 to clamp quick connectors 50 of different sizes. This ensures that the two clamping plates 33 firmly clamp the quick connector 50 and prevents the quick connector 50 from sliding or falling off during the test.

[0019] As shown in Figures 1, 2, 3, and 5, a cover plate 34 is placed on top of the base 31. The cover plate 34 has a second through hole 341, which corresponds to a clamping opening 35. The diameter of the clamping opening 35 is smaller than that of the second through hole 341, allowing the quick connector 50 to pass through the second through hole 341, the clamping opening 35, and the first through hole 312 to form a channel for accommodating the quick connector 50, which is then clamped by the clamping parts 331 of the two clamping plates 33. In addition, the upper edge of the cover plate 34 is provided with a plurality of sixth locking holes 342. The positions of these sixth locking holes 342 correspond to the fifth locking holes 314 on the base 31. The cover plate 34 is fixed to the base 31 by a third fastener 43 to provide downward pressure, further fixing the clamping plates 33 and restricting their vertical movement.

[0020] The first through hole 312, the clamping opening 35, the second through hole 341 and the third through hole 13 connect to the operating space 40.

[0021] The first locking component 41, the second locking component 42, the third locking component 43 and the fastener 44 may be screws or any mechanism that can be used for fixing and locking.

[0022] The tester first assembles the clamping fixture 1. When the quick connector 50 needs to be tested, the quick connector 50 is passed from top to bottom through the second through hole 341, the clamping opening 35 and the first through hole 312. The clamping part 331 of the clamping piece 33 is aligned with the position where the quick connector 50 can be clamped (such as the waist, the groove position, etc.). The fastener 44 on the side of the locking base 31 pushes the clamping piece 33 to lock the quick connector 50. Then, the adapter 52, which has been installed on the third through hole 13 of the base 10, is connected to the hose 51 at its upper end and assembled with the pagoda end interface of the quick connector 50. After the assembly is completed, the pressure medium test process can be carried out.

[0023] This invention provides a detachable clamping fixture 1, specifically designed for the rapid fixing and testing of quick connectors 50 with special shapes. Its robust structure and adjustable clamping function not only accommodate quick connectors 50 of various sizes and shapes but also effectively prevent slippage or detachment during testing due to insecure clamping. Furthermore, the detachable and interchangeable design of the base 10, support 20, and clamping unit 30 makes the overall clamping fixture flexible, allowing for rapid adjustments to meet different testing needs, further improving testing efficiency and accuracy.
