Description

Technical Field

[0001] The utility model relates to the technical field of automobile radiators, in particular to an outer baffle positioning tool. Background Art

[0002] The car radiator is an important part of the engine cooling system. Its main function is to transfer the heat generated by the engine to the coolant, and then dissipate the heat into the air through the radiator to keep the engine running within a suitable operating temperature range.

[0003] Automobile radiators are generally composed of components such as heat sinks, water tanks, water inlets, water outlets, fans and guard plates. The heat generated by the engine is transferred to the radiator through the coolant. The coolant flows in the heat sink and exchanges heat with the outside air to dissipate the heat. The function of the fan is to increase air flow and speed up the heat dissipation. The guard plate, that is, the outer baffle, usually has two pieces, namely the left outer baffle and the right outer baffle. By connecting the outer baffle to the radiator, it can not only protect the radiator, thereby preventing the radiator from being damaged by external objects, but also guide the flow of air.

[0004] CN202053882U discloses an automobile cooling device, including a radiator assembly and an intercooler assembly. The radiator assembly and the intercooler assembly are connected by a casting bracket with a through hole, a nut and a bolt assembly. One of the radiator assembly and the intercooler assembly is welded with a nut, and the other is provided with a casting bracket. The bolt assembly includes a bolt and a washer, and the bolt passes through the through hole of the casting bracket. The through hole on the casting bracket reserved on the intercooler air chamber and the mounting hole for the inner welding nut on the water tank guard plate are connected by bolts, thereby improving reliability.

[0005] The above technical solution simplifies the assembly process, bolts the round hole on the reserved casting bracket on the air chamber of the intercooler and the mounting hole of the inner welded nut on the water tank guard plate, improves reliability, and makes the entire connection method bolted, which is more convenient for disassembly. However, when processing the mounting hole of the inner welded nut on the water tank guard plate, it is necessary to manually position the nut to be welded, which is very troublesome and easy to be welded off.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] refer to Figures 1 to 4 A tool for positioning an outer baffle plate comprises a workbench 1, on which a support plate 2 and a support column 3 for respectively supporting two ends of an outer baffle plate 5 are provided, on which a fixing groove 21 matching the outer baffle plate 5 is provided, and the fixing groove 21 is fitted with the outer side surface of the outer baffle plate 5, and the support column 3 matches the position of an inner welding nut mounting hole 51 on the outer baffle plate 5 and is plugged into the inner welding nut mounting hole 51, and the inner welding nut 6 is sleeved on the support column 3, and the bottom of the inner welding nut 6 is fitted with the outer baffle plate 5.

[0019] Under this design, the operator places one end of the outer baffle plate 5 in the fixing groove 21 of the support plate 2 and fits with the fixing groove 21, limits one end of the outer baffle plate 5, and then places the other end of the outer baffle plate 5 in alignment with the support column 3, and plugs the inner welding nut installation hole 51 on the outer baffle plate 5 with the support column 3 to complete the positioning of the outer baffle plate 5, and finally sleeves the inner welding nut 6 on the support column 3, and the inner welding nut 6 moves downward along the support column 3 by its own gravity, so that its bottom fits with the outer baffle plate 5, and the positioning of the inner welding nut 6 is completed, and the operator can perform the welding process. In this way, the verticality of the inner welding nut 6 and the accuracy of the welding position are guaranteed, and the welding efficiency is improved.

[0020] Preferably, the support plate 2 is a U-shaped structure, and the opening of the U-shaped structure is the fixing groove 21. The support plate 2 adopts a U-shaped structure so that the support plate 2 has an opening, and the opening can be used as the fixing groove 21. However, the size of the fixing groove 21 needs to match the outer baffle 5 to ensure that the outer baffle 5 can fit with the fixing groove 21 and limit the outer baffle 5.

[0021] In this embodiment, there are two or more support plates 2, and the support plates 2 are used to support one end and the middle part of the outer baffle 5. We found that if only the two ends of the outer baffle 5 are supported, the middle part may be deformed during welding. Therefore, in order to avoid this situation, two or more support plates 2 are used, that is, one support plate 2 is used to support one end of the outer baffle 5, and the other support plate 2 is used to support the middle part of the outer baffle 5. Of course, for a longer outer baffle 5, multiple support plates can also be used to ensure the stability of the support. This embodiment chooses to use two based on the premise of economy and stability.

[0022] Preferably, the support column 3 includes a column 31 connected to the workbench 1 and a positioning column 32 connected to the column 31, the bottom of the outer baffle 5 is fitted with the top of the column 31, the positioning column 32 is plugged into the internal welding nut mounting hole 51, and the internal welding nut 6 is sleeved on the positioning column 32.

[0023] In actual use, after one end of the outer baffle plate 5 is fixed by the support plate 2, the other end is aligned with the positioning column 32, and the positioning column 32 is plugged into the inner welding nut mounting hole 51. At this time, the bottom of the outer baffle plate 5 will fit with the top of the column 31 to support the other end of the outer baffle plate 5, and then the inner welding nut 6 is sleeved on the positioning column 32 to ensure the position accuracy of the inner welding nut 6.

[0024] More preferably, in this embodiment, it also includes a limit plate 33, the limit plate 33 is connected to the column 31, the positioning column 32 is connected to the limit plate 33, the outer diameter of the limit plate 33 matches the aperture of the internal welding nut mounting hole 51, the outer diameter of the positioning column 32 is smaller than the aperture of the internal welding nut mounting hole 51, and the outer diameter of the positioning column 32 matches the outer diameter of the internal welding nut 6.

[0025] Specifically, because the internal welding nut 6 used is generally smaller than the aperture of the internal welding nut mounting hole 51, that is, the outer diameter of the positioning column 32 must match the inner welding nut 6 to ensure the position accuracy of the inner welding nut 6. However, in the absence of the limiting plate 33, we found that since the outer baffle plate 5 only has longitudinal limitation and no lateral limitation, and the outer diameter of the positioning column 32 is smaller than the aperture of the inner welding nut mounting hole 51, the outer baffle plate 5 has some room for movement in the lateral direction, which may also cause a slight position offset of the internal welding nut 6 during welding. In order to avoid such a situation, by adding a limiting plate 33, the outer diameter of the limiting plate 33 matches the aperture of the inner welding nut mounting hole 51. Then, after the positioning column 32 is plugged into the inner welding nut mounting hole 51, the inner welding nut mounting hole 51 will be completely fitted with the limiting plate 33, thereby preventing the lateral movement of the outer baffle plate 5 and ensuring the position accuracy of the welding of the inner welding nut 6.

[0026] Optionally, the top of the positioning column 32 is in a spherical cap shape. The spherical cap shape of the top of the positioning column 32 can facilitate the internal welding nut 6 to be sleeved on the positioning column 32, and can know whether the size of the internal welding nut 6 is selected incorrectly during the sleeve. If it can be just inserted and the internal welding nut 6 does not shake, it proves that the specification of the internal welding nut 6 is correct; if it cannot be inserted, it is stuck at the spherical cap, or after being inserted, the internal welding nut 6 can shake, it proves that the specification of the internal welding nut 6 is wrong.

[0027] More preferably, the column 31, the stopper 33, and the positioning column 32 are an integrally formed structure. The advantage of integrally forming is that it can provide higher structural strength and stability, reduce the connection points of parts, and reduce the risk of damage. This manufacturing method can also improve production efficiency and reduce production costs.

[0028] In this embodiment, a fixing block 4 is further provided on the workbench 1 , and a positioning groove 41 is provided on the fixing block 4 . The positioning groove 41 matches with the connecting piece 7 of the external device, and the fixing block 4 is used to press the connecting piece 7 of the external device against one side of the outer baffle 5 .

[0029] In the outer baffle plate 5 of the present embodiment, a connecting piece 7 needs to be installed on one side of the outer baffle plate 5. The function of the connecting piece 7 is to fix the radiator on the structure of the peripheral device for easy installation and disassembly. In order to ensure the position accuracy and stability of the connecting piece 7, the present embodiment arranges a fixing block 4 on the workbench 1, and arranges a positioning groove 41 on the fixing block 4 that matches the connecting piece 7 of the peripheral device. After the connecting piece 7 of the peripheral device is placed on the positioning groove 41, the connecting piece 7 can be pressed against one side of the outer baffle plate 5, thereby ensuring the position accuracy and stability of the connecting piece 7.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements or modifications without departing from the principle of the present invention. These improvements or modifications should also be regarded as within the protection scope of the present invention.
