[0029] like Figure 1 , which is a schematic diagram of the structure of the heat exchanger core quick clamping tool provided in this embodiment, mainly consists of a tool body 1, a clamping block 2, a clamping mechanism 3, a movable mechanism 4, a connecting rod 5, a first fastening screw 6, a second fastening screw 7 and a third fastening screw 8.

[0030] See also Figure 2-3 The tool body 1 is a hollow rectangular profile with a size of 22x22mmx4mm and a material of 6061 aluminum alloy. It serves as the carrier of the entire tool. An L-shaped clamping block 2 with a size of 13.8mmx13.8mmx110mm and a material of 6061 aluminum alloy is inserted on the left side of the tool body 1 and fixed by a first fastening screw 6. It serves as a clamping point at one end of the clamping tool.

[0031] like Figure 4 , which is a schematic diagram of the structure of the clamp mechanism 3 in this embodiment, the model is CH-43120, the mounting base is mounted on the tool body 1 through the second fastening screw 7, and the other end can be deflected around the axis at the hinge point with the mounting base. Figure 5-6, respectively, are the structural schematic diagram and cross-sectional view of the tensioning mechanism 41 and the sliding block 42 in this embodiment, which together form the movable mechanism 4. The sliding block 42 is L-shaped, with specifications of 13.8mmx13.8mmx165mm, and is made of aluminum alloy. The tensioning mechanism 41 is fixed to the sliding block 42 by the third fastening screw 8, and the sliding block 42 is movably plugged into the other end of the tool body 1, serving as a movable clamping point at the other end of the clamping tool.

[0032] like Figure 7-9 As shown, in this embodiment, the tensioning mechanism 41 includes a cylinder 411, a compression spring 412, a nut 413, a pin 414 and a fixed block 415. The cylinder 411 is a cylindrical structure, and a compression spring 412 and a nut 413 are installed at one end of the cylinder. The outside of one end of the cylinder 411 is hinged to the fixed block 415 through the pin 414, and the fixed block 415 is connected to the sliding block 42 through the third fastening screw 8 as mentioned above.

[0033] It should be noted that the compression spring 412 and the nut 413 are both movable in the cylinder 411. The elastic force of the compression spring 412 itself pushes the nut 413 against the inner wall of the cylinder 411 close to the fixed block 415. One end of the connecting rod 5 is movable through the end of the cylinder 411 away from the fixed block 415, and passes through the middle of the compression spring 412 to be fastened and connected with the nut 413. Therefore, pulling the connecting rod 5 can drive the nut 413 to move to the left in the cylinder 411, and squeeze the compression spring 412, loosening the connecting rod 5. After that, the compression spring 412 drives the nut 413 to move rightward and reset. The end of the connecting rod 5 away from the nut 413 is connected to the deflection part of the clamping mechanism 3, thereby pulling the clamping mechanism 3 to deflect and drive the connecting rod 5 and the movable mechanism 4 to move, thereby driving the sliding block 42 to move toward the clamping block 2, and the bottom ends of the clamping block 2 and the sliding block 42 are used to quickly clamp the heat exchanger core. The reverse deflection of the deflected clamping mechanism 3 can reset the tensioning mechanism 41 and the sliding block 42, loosen the heat exchanger core, and realize a quick clamping and releasing action.

[0034] like Fig.10 As shown, they are schematic diagrams of the structures of the first fastening screw 6, the second fastening screw 7 and the third fastening screw 8. In the present embodiment, the first fastening screw 6 has a specification of M8x35mm, the second fastening screw 7 has a specification of M6x20mm, the third fastening screw 8 has a specification of M5x20mm, and the connecting rod 5 is made of SUS304 stainless steel. In some other embodiments, the size of each fastening screw and the material of the connecting rod 5 can also be designed and adjusted as needed.

[0035] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
