Description

Technical Field

[0001] This utility model relates to the field of tooling technology, and more specifically, to a clamping tool for the left and right frames of a liquid cooler. Background Technology

[0002] In the structural design of liquid cooler cabinets, the left and right side frames are typically composed of two vertically parallel first support rods, which are laterally connected by multiple horizontal rods to form a stable main frame. To further enhance the overall load-bearing capacity, corresponding horizontal rods on the left and right frames are connected by longitudinal rods, and the main equipment of the liquid cooler cabinet is placed directly on the longitudinal rods to achieve even force support. In addition, a second support rod is set at the front of the frame, which is fixedly connected to the first support rod by multiple wiring boards. The second support rod also serves to connect the cabinet door, ensuring the stability of the cabinet's opening and closing and the structural integrity.

[0003] However, during the welding and manufacturing process of liquid cooler frames, the lack of dedicated welding fixtures often makes it difficult to maintain precise positioning of components during the assembly and fixing stage. During welding, workpieces are susceptible to displacement due to thermal deformation or external forces, leading to deviations in the welding position and consequently affecting the overall structural dimensional accuracy and assembly quality. This problem not only increases the workload of subsequent corrections but may also adversely affect the mechanical properties and long-term reliability of the liquid cooler. Therefore, developing a dedicated fixture that can effectively fix workpieces and reduce welding deformation has become a key requirement for improving the stability of the welding process for liquid cooler frames. Summary of the Invention

[0004] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, the embodiments of this utility model propose a clamping fixture for the left and right frames of a liquid cooler. Through precise positioning and multi-point clamping, it reduces the risk of deformation during the welding process, improves the consistency of frame welding dimensions and structural stability, while improving production efficiency, assembly quality, and reducing subsequent correction time.

[0005] The technical solution adopted by this utility model is: to provide a clamping fixture for the left and right frames of a liquid cooler, comprising:

[0006] The first clamping mechanism includes a support, a first clamping cylinder, a mounting base, a second clamping cylinder, and a third clamping cylinder. The support is used to support the crossbar on the frame. The first clamping cylinder is used to clamp and fix the crossbar. The second clamping cylinder is fixedly mounted on the mounting base and is used to clamp and fix the wiring board. The third clamping cylinder is used to clamp and fix the second support rod.

[0007] The second clamping mechanism is used to fix the first support rod.

[0008] With the above structure, the left and right frames of the liquid cooler can be precisely positioned and firmly fixed before welding using specialized clamping fixtures. This prevents displacement of key components during welding due to thermal expansion and contraction or external forces, effectively improving the consistency of weld dimensions and structural stability. Specifically, the first clamping mechanism can simultaneously clamp the crossbar, wiring board, and second support rod at multiple points, ensuring accurate positional relationships between connected components. The second clamping mechanism is specifically used to fix the first support rod, further enhancing the overall rigidity of the entire frame.

[0009] During use, operators only need to initially assemble the left and right frames of the liquid cooler and place them in the fixture. The clamping components are then driven sequentially by cylinders to quickly complete the positioning preparation, significantly improving production efficiency. Furthermore, because each clamping component uses an independently controlled cylinder drive, the clamping force and position can be finely adjusted according to the actual workpiece size, providing good adaptability and flexibility. In addition, this clamping fixture has a compact structure, occupies little space, and is easy to deploy and use on the production floor.

[0010] The above technical solutions not only effectively reduce the risk of deformation during the welding process of the liquid cooler frame and improve product consistency and assembly quality, but also reduce the time required for subsequent corrections and debugging, which helps to improve overall production efficiency and product reliability.

[0011] According to one embodiment of the present invention, the second clamping mechanism includes a clamping cylinder, an upper clamping plate, and a lower clamping plate. The lower clamping plate is used to support the first support rod, and the clamping cylinder is used to drive the upper clamping plate to move vertically toward or away from the lower clamping plate, so as to clamp and fix the first support rod.

[0012] According to one embodiment of the present invention, the moving end of the clamping cylinder is equipped with an mounting plate, and the upper clamping plate is fixedly installed at the bottom of the mounting plate. The clamping cylinder drives the mounting plate and the upper clamping plate to move vertically as a whole, thereby clamping or releasing the first support rod. The structure is compact, the transmission is reliable, and it is beneficial to improve clamping efficiency and stability.

[0013] According to one embodiment of the present invention, the second clamping mechanism further includes a slide rail seat and a slider. The slider is slidably mounted on the slide rail seat, and the clamping cylinder is fixedly mounted on the slider. By moving the slider on the slide rail seat, the lateral position of the clamping cylinder and the upper clamping plate can be adjusted to adapt to the first support rod of different specifications or positions, thereby improving the adaptability and operational flexibility of the tooling.

[0014] According to one embodiment of the present invention, a push cylinder is installed on one side of the slide rail seat. The push cylinder is used to drive the slider to move laterally towards or away from the lower clamping plate, thereby driving the clamping cylinder and the upper clamping plate to adjust their positions. In conjunction with the vertical movement of the clamping cylinder, not only can the first support rod be accurately clamped, but the clamping position can also be flexibly adjusted according to different workpiece sizes, further improving the applicability and ease of operation of the clamping fixture.

[0015] According to one embodiment of the present invention, the second clamping mechanism further includes an upper lifting cylinder, which is used to lift the first support rod. After the first support rod is positioned, the upper lifting cylinder applies an upward lifting force to prevent the first support rod from drooping due to its own weight or external force, ensuring that it is in an accurate height and posture before welding, thereby improving welding accuracy and consistency with the finished product.

[0016] According to one embodiment of the present invention, the second clamping mechanism further includes an end clamping cylinder, which is used to clamp the end of the first support rod to provide additional axial limiting and support for the first support rod, preventing axial displacement or rotation during welding, and further improving positioning accuracy and overall structural stability.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0031] like Figure 1-7 As shown, this embodiment discloses a clamping fixture for the left and right frames 10 of a liquid cooler, including:

[0032] The first clamping mechanism 20 includes a support 21, a first clamping cylinder 22, a mounting base 23, a second clamping cylinder 24, and a third clamping cylinder 25. The support 21 is used to support the crossbar 12 on the frame 10. The first clamping cylinder 22 is used to clamp and fix the crossbar 12. The second clamping cylinder 24 is fixedly mounted on the mounting base 23 and is used to clamp and fix the wiring board 14. The third clamping cylinder 25 is used to clamp and fix the second support rod 13.

[0033] The second clamping mechanism 30 is used to fix the first support rod 11.

[0034] Furthermore, in this embodiment, the first clamping mechanism 20 is arranged horizontally to distribute and fix multiple crossbars 12 on the left and right frames 10 of the liquid cooler. Specifically, for each crossbar 12, a set of first clamping cylinders 22 is provided on both the left and right sides to achieve synchronous clamping and precise positioning of both ends of the crossbar 12. To meet the overall fixing requirements of multiple crossbars 12, this embodiment has two rows of five rows of first clamping cylinders 22 on the first clamping mechanism 20, that is, arranged in five rows along the longitudinal direction, with two rows of first clamping cylinders 22 distributed in each row, corresponding to the left and right sides of the same crossbar 12, to achieve an efficient and stable clamping effect. Each row of first clamping cylinders 22 is evenly arranged in the transverse direction, which can effectively ensure that the overall frame 10 is subjected to uniform force and prevent local deformation during the welding process. At the same time, the number of second clamping cylinders 24 is set according to the number of wiring boards 14 to ensure that each wiring board 14 has a dedicated clamping cylinder for fixing, improving the accuracy and stability of wiring board 14 installation. To accommodate the arrangement of the second support rod 13, the mounting base 23 is arranged in a direction parallel to the second support rod 13, which helps to improve the overall layout and the convenience of clamping operation.

[0035] Furthermore, in this embodiment, the second clamping mechanism 30 has a more complete structure, mainly including a clamping cylinder 34, an upper clamping plate 36, a lower clamping plate 37, a slide rail seat 31, a slider 32, a pushing cylinder 33, an upper lifting cylinder 38, and an end clamping cylinder 39. Specifically, the lower clamping plate 37 is used to support the first support rod 11 and support and position it in the horizontal direction. The clamping cylinder 34 is used to drive the upper clamping plate 36 to move towards or away from the lower clamping plate 37 in the vertical direction to clamp or release the first support rod 11, thereby achieving a fast and reliable vertical clamping effect. The moving end of the clamping cylinder 34 is connected to a mounting plate 35, and the upper clamping plate 36 is fixedly installed on the bottom of the mounting plate 35 by a mounting component, making the clamping action transmission more stable and the clamping process more smooth and reliable. The slider 32 is slidably mounted on the slide rail seat 31, and the clamping cylinder 34 is integrally mounted on the slider 32. The smooth sliding of the slider 32 on the slide rail seat 31 allows for flexible horizontal adjustment of the clamping cylinder 34. To further improve adjustment efficiency, a push cylinder 33 is provided on one side of the slide rail seat 31. The push cylinder 33 drives the slider 32 to move the clamping cylinder 34 and the upper clamping plate 36 laterally towards or away from the lower clamping plate 37, facilitating rapid alignment and clamping according to different positions of the first support rod 11. To prevent the first support rod 11 from sagging due to its own weight during positioning, thus affecting welding accuracy, an upper lifting cylinder 38 is specially provided to apply force from below to lift the first support rod 11, ensuring it is at the correct height. Furthermore, the end clamping cylinder 39 is used to clamp the end of the first support rod 11, further preventing axial displacement or rotation of the first support rod 11 during welding, enhancing the overall clamping stability and welding consistency.
