Description

Technical Field

[0001] This utility model belongs to the field of welding fixture technology, and specifically relates to a water-cooled plate welding fixture. Background Technology

[0002] Water-cooled plates, as a highly efficient thermal management core component, are widely used in new energy power batteries, servers, power electronic equipment, and other fields. They typically consist of a thin metal cavity with internal flow channels, where circulating coolant rapidly dissipates heat generated by electronic devices, ensuring stable operation of the equipment at suitable temperatures. During the manufacturing process, the cover plate and base plate must be reliably sealed by welding (such as friction stir welding, brazing, laser welding, etc.) to form a closed flow channel. The welding quality directly determines the sealing performance, pressure resistance, and long-term reliability of the water-cooled plate, and is crucial to the performance and lifespan of the final product.

[0003] During the welding process of water-cooled plates, specialized fixtures are required to precisely position and securely clamp the cover plate, base plate, and any internal turbulence structures to prevent welding thermal deformation and misalignment. However, currently used water-cooled plate welding fixtures are typically complex in structure, containing numerous customized positioning blocks, clamping mechanisms, and other components; the operation is cumbersome, with time-consuming and labor-intensive clamping and disassembling of the water-cooled plates; and they are difficult to adapt to water-cooled plate products of different lengths, widths, or thicknesses. Therefore, developing a welding fixture with a relatively simple structure, convenient operation, and flexible adaptability to various sizes of water-cooled plates has become an urgent technical problem to be solved. Utility Model Content

[0004] The purpose of this invention is to develop a welding fixture that is relatively simple in structure, easy to operate, and can be flexibly adapted to water-cooled plates of various sizes.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A water-cooled plate welding fixture includes a worktable and multiple sets of movable fixtures. Each movable fixture includes a positioning post and a pressing mechanism disposed on the upper end of the positioning post. The worktable has several insertion holes, and the lower end of each insertion hole has a slot. The interior of the positioning post has an installation slot near its lower end. A protruding post is fixedly installed at the center of the bottom of the installation slot. Two movable blocks are symmetrically and movably installed in the installation slot. Two compression springs are fixedly installed between each movable block and the protruding post. When the positioning post is inserted into the insertion hole and the slot, the two movable blocks are engaged in the slot. The positioning post is provided with a pulling component that can pull the two movable blocks to move towards each other.

[0007] Further specifying, the pulling assembly includes two pull ropes and a pull rod. A strip-shaped through hole is formed in the middle of the positioning post. A connecting groove is formed inside the positioning post between the strip-shaped through hole and the mounting groove. The two pull ropes are respectively fixedly connected to two movable locking blocks. The pull rod is movably installed within the strip-shaped through hole and has two limiting protrusions. The upper ends of the two pull ropes are fixedly connected to the pull rod through the connecting groove. With this structural design, when the pull rod is pulled upwards, the pull ropes can pull the two movable locking blocks to move towards each other, facilitating the release of the two movable locking blocks from the locking groove.

[0008] Furthermore, a fixing plate is fixedly installed on the positioning post below the strip-shaped through hole, and a rubber pad is provided at the lower end of the fixing plate. This structural design allows the fixing plate to stabilize the positioning post and prevent it from shaking.

[0009] Further defining the pressing mechanism, it includes a fixed base, a rod, a pressure plate, and a fixed end. The fixed base is fixedly installed on the upper end of the positioning column. A rectangular socket is provided on the fixed base, and the rod is movably inserted into the rectangular socket. The pressure plate and the fixed end are respectively fixedly installed at the upper and lower ends of the rod. An L-shaped groove communicating with the rectangular socket is provided at the upper end of the fixed base. An L-shaped block is movably installed in the L-shaped groove. A return spring is fixedly installed between the L-shaped block and the groove wall. A wedge-shaped block is provided at one end of the L-shaped block extending into the rectangular socket, and a toggle post is fixedly installed at the other end. A one-way locking groove assembly adapted to the wedge-shaped block is provided on the side of the rod near the L-shaped block. With this structural design, when the rod is pushed downwards by the fixed end, the wedge-shaped block at the end of the L-shaped block continuously engages with the one-way locking groove assembly, providing a one-way locking effect on the rod and ensuring that the pressure plate presses the upper end of the water-cooled plate firmly.

[0010] Furthermore, a guide frame is fixedly installed on the outer side of the rectangular socket on the fixed base. This structural design allows the guide frame, in conjunction with the rectangular socket, to guide the insertion rod, enabling the rod to move vertically up and down.

[0011] Furthermore, both the lower end of the pressure plate and the upper end of the worktable are provided with an anti-slip coating. This structural design increases the friction between the water-cooled plate workpiece and the worktable and pressure plate, resulting in more stable positioning.

[0012] The utility model employing the above technical solution has the following advantages:

[0013] In this invention, when the positioning post is inserted into the slot, two movable blocks will engage in the slot, facilitating the installation of the movable clamp. By pulling the two movable blocks upward with the pull rod and pull rope, the two movable blocks can be moved towards each other, thereby releasing the movable clamp from the slot and facilitating disassembly. The clamp has a simple structure, is easy to operate, and can be adapted to water-cooled plate products of different lengths, widths, or thicknesses. Attached Figure Description

[0034] like Figures 1 to 7 As shown, this utility model discloses a water-cooled plate welding fixture, including a workbench 1 and multiple sets of movable fixtures. The movable fixtures include positioning posts 2 and a pressing mechanism 3 set on the upper end of the positioning posts 2. The workbench 1 has several insertion holes 11, and the lower end of the insertion holes 11 is provided with a slot 12. The interior of the positioning posts 2 is provided with an installation groove 21 near the lower end. A protruding post is fixedly installed at the center of the bottom of the groove wall of the installation groove 21. Two movable locking blocks 22 are symmetrically and movably installed in the installation groove 21. Two compression springs 23 are fixedly installed between the two movable locking blocks 22 and the protruding post. When the positioning posts 2 are inserted into the insertion holes 11 and the slots 12, the two movable locking blocks 22 are locked into the slots 12. The positioning posts 2 are provided with a pulling component that can pull the two movable locking blocks 22 to move towards each other.

[0035] The pulling assembly includes two pull ropes 24 and a pull rod 241. A strip-shaped through hole is provided in the middle of the positioning post 2. A connecting groove is provided inside the positioning post 2 between the strip-shaped through hole and the mounting groove 21. The two pull ropes 24 are fixedly connected to two movable blocks 22 respectively. The pull rod 241 is movably installed in the strip-shaped through hole. Two limiting protrusions are provided on the pull rod 241. The upper ends of the two pull ropes 24 are fixedly connected to the pull rod 241 through the connecting groove. A fixing plate 4 is fixedly installed on the positioning post 2 below the strip-shaped through hole. A rubber pad is provided at the lower end of the fixing plate 4.

[0036] The pressing mechanism 3 includes a fixed base 31, a rod 32, a pressure plate 33, and a fixed end 34. The fixed base 31 is fixedly installed on the upper end of the positioning post 2. A rectangular socket is provided on the fixed base 31, and the rod 32 is movably inserted into the rectangular socket. A rubber block is provided inside the rectangular socket. The rubber block can generate resistance when the rod 32 moves. When the rod 32 is not subjected to external force, the resistance generated by the rubber block is greater than the overall weight of the rod 32, the pressure plate 33, and the fixed end 34. A guide frame 311 is fixedly installed on the fixed base 31 outside the rectangular socket. The pressure plate 33 and the fixed end 34 are respectively fixedly installed at the upper and lower ends of the rod 32. The lower end of the pressure plate 33... Both the upper end of the workbench 1 and the upper end of the workbench 1 are provided with anti-slip coating. The upper end of the fixed base 31 is provided with an L-shaped groove that communicates with the rectangular socket. An L-shaped block 35 is movably installed in the L-shaped groove. A return spring 36 is fixedly installed between the L-shaped block 35 and the wall of the L-shaped groove. A wedge block is provided at one end of the L-shaped block 35 that extends into the rectangular socket, and a toggle post is fixedly installed at the other end. A one-way slot group 321 that matches the wedge block is provided on the side of the insertion rod 32 near the L-shaped block 35. The one-way slot group 321 does not completely penetrate to the other two sides of the insertion rod 32. When the insertion rod 32 moves vertically up and down, the one-way slot group 321 will not collide with the rectangular socket or the guide frame 311.

[0037] The method of using this utility model is as follows:

[0038] When in use, place the water-cooled plate on the workbench 1. According to the size of the water-cooled plate, place multiple sets of movable clamps on the workbench 1 so that the pressing mechanism 3 of the movable clamps is located above the water-cooled plate. When placing the movable clamps, the positioning pin 2 needs to be aligned with the insertion hole 11 and pressed down until the two movable blocks 22 extend into the slot 12 under the elastic force of the compression spring 23.

[0039] After the multiple sets of movable clamps are installed, the insertion rod 32 and pressure plate 33 are pushed downward by the fixed end 34. When the insertion rod 32 moves downward, the L-shaped block 35 extends into the one-way slot of the one-way slot group 321 under the elastic force of the return spring 36. When the pressure plate 33 is pressed against the upper end of the water-cooled plate, the insertion rod 32 and the pressure plate 33 can maintain the pressing effect on the water-cooled plate.

[0040] When the movable clamp needs to be disassembled, the finger hooks the lever 241 upward, and the pull rope 24 drives the two movable blocks 22 to move towards each other, which can release the two movable blocks 22 from the slot 12, making it easier to pull the positioning post 2 out of the insertion hole 11 and the slot 12, thereby completing the disassembly of the movable clamp.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
