[0032] Reference below Figures 1 to 3 A radiator cover, a production jig, and a production method according to embodiments of the present invention are described.

[0033] The radiator cover of the first embodiment of the present invention includes a cover body 100 and two joints. The cover body 100 is arranged horizontally, and the cover body 100 is provided with two flow-conducting holes. The joint includes an inner connecting portion 112, a main body 110 and an outer connecting portion 111. The top surface of the main body 110 is parallel to the cover body 100, the outer connecting portion 111 extends horizontally and is arranged below the top surface of the main body 110, and the inner connecting portion 112 is arranged on the lower side of the main body 110 and connected to the edge of the flow-conducting hole.

[0034] For example, Figure 1 As shown, the cover plate body 100 is in the shape of a rectangular plate. Of course, the cover plate body 100 can also be circular, triangular or other required shapes. The two joints can be set at the corresponding positions of the cover plate body 100 according to the actual usage scenario. A first inner cavity is provided in the main body 110, the inner connecting part 112 is in the shape of a vertically arranged tube, a second inner cavity is provided in the inner connecting part 112, the outer connecting part 111 is in the shape of a horizontally arranged tube, and a third inner cavity is provided in the outer connecting part 111. The third inner cavity, the first inner cavity, the second inner cavity and the guide hole are connected in sequence, so that the cooling water can flow into the radiator from the outer connecting part 111 of one of the joints, and then flow out from the outer connecting part 111 of the other joint; wherein, the main body 110, the outer connecting part 111 and the inner connecting part 112 can be an integrally molded component. Of course, in some other embodiments of the present invention, the joint can also be composed of three independent components: the main body 110, the outer connecting part 111 and the inner connecting part 112.

[0035] By setting the top surface of the main body 110 parallel to the cover body 100, the pressure plate 230 can be used to cover the upper side of the two joints during production, and then a downward force is applied to the pressure plate 230 to press the two joints onto the cover body 100, thereby completing the positioning of the joints and preventing the joints from shifting, facilitating subsequent welding operations and achieving the purpose of facilitating production and manufacturing.

[0036] In some embodiments of the present invention, the edge of the guide hole is welded to the inner connecting portion 112. This provides a strong structure and good airtightness.

[0037] Of course, in some other embodiments of the present invention, the inner connection portion 112 and the flow guide hole may also be connected by threaded connection, bonding, sealing ring connection or other suitable means, as long as the connection between the inner connection portion 112 and the flow guide hole is sealed.

[0038] In some embodiments of the present invention, the flow-through hole is a countersunk hole. Figure 2 , the inner connecting portion 112 is inserted from top to bottom into the upper side of the flow-guiding hole; this facilitates preliminary fixation of the joint before welding;

[0039] The guide hole has an upper hole section and a lower hole section. The outer diameter of the lower end of the inner connecting portion 112 is larger than the diameter of the lower hole section, so that after the inner connecting portion 112 is inserted into the guide hole, the inner connecting portion 112 abuts against the upper side of the lower hole section to complete the vertical positioning;

[0040] The outer diameter of the lower end of the inner connecting portion 112 is smaller than the diameter of the upper hole section. In the subsequent welding operation, the solder can be filled between the inner wall of the upper hole section and the inner connecting portion 112, which facilitates welding. Of course, in some other embodiments of the present invention, the lower end of the inner connecting portion 112 can also be loosely matched with the upper hole section, which facilitates accurate positioning between the inner connecting portion 112 and the flow-through hole.

[0041] In some embodiments of the present invention, two connectors are spaced apart, with both main bodies 110 positioned between the two external connectors 111. These connectors are referred to as the first connector and the second connector, respectively. The first connector is positioned to the left of the second connector, with the external connector 111 positioned to the left of the first connector and extending to the left. The external connector 111 of the second connector is positioned to the right of the second connector and extending to the right. This allows external water pipes to extend to the left and right, respectively, leaving ample space for installing external water pipes and facilitating subsequent installation and use.

[0042] In some embodiments of the present invention, the main body 110 is in the shape of a cuboid. The top surfaces of the two main bodies 110 are coplanar, the front side surfaces of the two main bodies 110 are coplanar, and the rear side surfaces of the two main bodies 110 are coplanar, so that the position of the main body 110 can be fixed with other fixing parts during welding.

[0043] The production fixture of the second embodiment of the present invention includes a pressing plate 230 and a base 200. The pressing plate 230 is arranged above the base 200. A placement space for the above-mentioned radiator cover is formed between the base 200 and the pressing plate 230. The front and rear sides of the base 200 are provided with clamps 210. The clamps 210 are provided with a downward pressing portion, which abuts against the top surface of the pressing plate 230.

[0044] Reference Figure 3 The pressing plate 230 and the base 200 are independent components. When in use, the pressing plate 230 can be taken out first, and then the cover body 100 and the joint are placed, and then the pressing plate 230 is covered. Then, the pressing plate 230 is pressed tightly with two clamps 210 to achieve the purpose of pressing the joint on the cover body 100. The production fixture has a simple structure and a small size, which makes it easy to put the production fixture and the radiator cover into a vacuum furnace for welding. After welding, release the clamps 210, remove the pressing plate 230, and then take out the radiator cover. The clamp 210 can be a quick clamp disclosed in patent CN218194659U, that is, the clamp 210 includes a clamp seat, a handle, a pressure handle, a connecting rod and a pressure block. The clamp seat is fixedly installed on the base 200, the handle is arranged vertically, and the lower end of the handle is hinged to the base 200. The pressure handle is arranged horizontally, and the pressure handle crosses the handle. One end of the pressure handle is hinged to the base 200, and a pressure block is provided at the other end of the pressure handle. The connecting rod is arranged vertically, the lower end of the connecting rod is hinged to the pressure handle, and the upper end of the connecting rod is hinged to the handle. The pressure block can be an elastic component such as rubber, and the pressure block is the lower pressing part; by bending the handle, the pressure handle can be flipped, and then the pressure block can be pressed or loosened.

[0045] In some embodiments of the present invention, a block 231 is provided at the bottom of the pressure plate 230. The right and left sides of the block 231 are respectively provided with right and left grooves. During use, the block 231 is inserted between the two connectors, positioning them in the left and right grooves, respectively. The left and right grooves prevent the connectors from deflecting, ensuring more precise positioning of the connectors.

[0046] In some embodiments of the present invention, the base 200 is provided with a right support assembly and a left support assembly, which are mirror-symmetrical. The left support assembly includes a push rod 221 and a stop block 220. The stop block 220 is provided with a transverse sliding hole. The push rod 221 is arranged to the left of the left groove and slides in the sliding hole. The stop block 220 is provided with a locking member 222 for locking the push rod 221. The two push rods 221 can respectively axially support the two external connecting parts 111, further fixing the joint and making the joint positioning more precise.

[0047] In some embodiments of the present invention, the stopper 220 is provided with a vertically arranged internally threaded through-hole. The locking member 222 is a bolt. The bottom end of the internally threaded through-hole is connected to the sliding hole, and the locking member 222 is disposed within the internally threaded through-hole. The bolt and the internally threaded through-hole are adapted to each other, resulting in a simple structure. Simply twisting the bolt can loosen or tighten the push rod 221, making operation easy.
