Description

Technical Field

[0001] This application belongs to the field of automotive radiator technology, specifically a welding positioning fixture for an outer baffle assembly. Background Technology

[0002] The car radiator is an important component 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 operating within a suitable temperature range.

[0003] A car radiator typically consists of components such as fins, a water tank, an inlet, an outlet, a fan, and a skid plate. Heat generated by the engine is transferred to the radiator via coolant. The coolant flows through the fins, exchanging heat with the outside air to dissipate heat. The fan increases airflow, accelerating heat dissipation. The skid plate, or outer baffle, usually consists of two parts: a left outer baffle assembly and a right outer baffle assembly. Connecting these assemblies to the radiator not only protects it from damage by external objects but also guides airflow.

[0004] However, the structure of the outer baffle assembly varies for different models of radiators. For new models of outer baffle assemblies, new welding positioning fixtures need to be developed to weld and position multiple accessories of the outer baffle assembly. Utility Model Content

[0005] The purpose of this application is to provide a welding positioning fixture for an outer baffle assembly. This welding positioning fixture uses magnetic blocks to accurately position the outer baffle and the first and second brackets that need to be welded to the outer baffle for the new model of outer baffle assembly.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0008] The top of the second magnetic block is provided with a protrusion, and the first bracket is provided with a through hole that matches the protrusion. The first bracket is attached to the top of the second magnetic block through the through hole and the protrusion. The protrusion can restrict the horizontal movement of the first bracket.

[0009] There are at least two first positioning posts, which are vertically arranged on the base plate. The outer baffle is placed on the two first magnetic blocks with its plate surface in a vertical state. The first positioning posts can restrict the horizontal movement of the outer baffle. At this time, the plate surface of the outer baffle is in contact with the first bracket.

[0010] Each of the two first magnetic blocks is provided with a vertically arranged second positioning post. The second positioning post is arranged adjacent to the surface of the outer baffle. The two second positioning posts pass through the two second brackets respectively, so that the two second brackets are in contact with the surface of the outer baffle.

[0011] Preferably, the outer baffle is provided with mounting plates on both sides along its length direction, and the mounting plates are provided with mounting holes. The axis of the mounting holes extends along the width direction of the outer baffle. The number of first positioning posts matches the number of mounting holes located on one side of the outer baffle. When the surface of the outer baffle is in a vertical state, the axis of the mounting holes is in a vertical state, and the first positioning posts pass through the mounting holes located on one side of the outer baffle, thus restricting the horizontal movement of the outer baffle.

[0012] Preferably, the welding positioning fixture for the outer baffle assembly further includes two third magnetic blocks and two first positioning posts. The two first positioning posts are respectively located on the two third magnetic blocks. The two third magnetic blocks are arranged at intervals on the base plate. The two first magnetic blocks are located between the two third magnetic blocks, and the two second magnetic blocks are located between the two first magnetic blocks. When the outer baffle is placed on the first magnetic blocks, the outer baffle simultaneously contacts the two second magnetic blocks.

[0013] Preferably, the outer baffle has bent portions at both ends along its length direction, which bend away from the plate surface. The bottom plate also has two fourth magnetic blocks, which are arranged at intervals on the bottom plate and match the positions of the two bent portions. The two third magnetic blocks are located between the two fourth magnetic blocks. When the outer baffle is placed on the first magnetic block, the outer baffle is in contact with the two second magnetic blocks and the two fourth magnetic blocks at the same time.

[0014] Preferably, there is a gap between each pair of adjacent magnetic blocks, including the first magnetic block, the second magnetic block, the third magnetic block, and the fourth magnetic block.

[0015] Preferably, the first support has an L-shaped structure, including a first horizontal part and a first vertical part, which are integrally formed. A through hole is located on the first horizontal part. The through hole is a strip-shaped through hole, and the end of the through hole away from the first horizontal part is open. The structure of the protrusion matches the through hole. When the first support is placed on the top of the second magnet, the first vertical part faces downward, and the sidewall of the first vertical part is in contact with the surface of the outer baffle.

[0016] Preferably, the second bracket has an L-shaped structure, including a second horizontal part and a second vertical part, which are integrally formed. The second horizontal part is provided with a connecting hole, which matches the second positioning post. When the second bracket is placed on the first magnetic block, the second positioning post passes through the connecting hole, and the side wall of the second vertical part is in contact with the surface of the outer baffle.

[0017] Preferably, the first magnetic block, the second magnetic block, the third magnetic block and the fourth magnetic block are all magnetic blocks or have at least a magnetic layer on the top.

[0018] Compared with the prior art, the beneficial effects of this application are:

[0019] 1. This application uses magnetic blocks to accurately position the outer baffle and the first and second brackets that need to be welded to the outer baffle. The magnetic force provided by the magnetic blocks can maintain the relative relationship of each accessory even after the hand is removed, ensuring accurate positioning.

[0020] 2. In this application, the first magnetic block, the second magnetic block, the third magnetic block and the fourth magnetic block position and support the main parts of the outer baffle assembly. For the parts that do not require positioning and support, gap treatment is directly applied to control costs. At the same time, while ensuring accurate positioning, the magnetic blocks reduce their attraction to the outer baffle, making it easier to remove the outer baffle after welding.

[0021] 3. The positioning of this application is completed by the method of positioning column insertion and overlapping. After the welding of the outer baffle, the first bracket and the second bracket are completed, the outer baffle assembly can be taken out by simply lifting it upward in the vertical direction. Not only is it convenient to place each component, but it is also convenient to take it out after welding is completed. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0032] Example 1

[0033] refer to Figures 1-7 A welding positioning fixture for an outer baffle assembly, the outer baffle assembly including an outer baffle A, a first bracket B and two second brackets C, the welding positioning fixture including a base plate 1, a first magnetic block 11, a second magnetic block 12 and a first positioning post 131 provided on the base plate 1; there are two first magnetic blocks 11, the two first magnetic blocks 11 are arranged at intervals on the base plate 1, and the second magnetic block 12 is located between the two first magnetic blocks 11;

[0034] The top of the second magnetic block 12 is provided with a protrusion 121, and the first bracket B is provided with a through hole B3 that matches the protrusion 121. The first bracket B is connected to the top of the second magnetic block 12 through the through hole B3 and the protrusion 121. The protrusion 121 can restrict the horizontal movement of the first bracket B.

[0035] At least two first positioning posts 131 are vertically arranged on the base plate 1. The outer baffle A is placed on the two first magnetic blocks 11 with its plate surface A4 in a vertical state. The first positioning posts 131 can restrict the horizontal movement of the outer baffle A. At this time, the plate surface A4 of the outer baffle A is in contact with the first bracket B.

[0036] Each of the two first magnetic blocks 11 is provided with a vertically arranged second positioning post 111. The second positioning post 111 is arranged adjacent to the plate surface A4 of the outer baffle A. The two second positioning posts 111 pass through the two second brackets C respectively, so that the two second brackets C are in contact with the plate surface A4 of the outer baffle A.

[0037] It should be noted that regarding the function of the outer baffle A, there are usually two outer baffles A, connected to both sides of the radiator. They not only protect the radiator from damage by external objects, but also guide airflow. The outer baffles positioned and welded in this application are collectively referred to as the right outer baffle A. Regarding the first bracket B, the through hole B3 on the first bracket B is used to assist in the positioning of pipes or lines, allowing pipes to pass through the through hole B3. Regarding the second bracket C, the second bracket C is used for the installation of the radiator.

[0038] It should also be noted that the outer baffle A, the first bracket B, and the second bracket C are all made of magnetic material. That is to say, when the outer baffle A is in contact with the first magnetic block 11, when the first bracket B is in contact with the second magnetic block 12, and when the second bracket C is in contact with the first magnetic block 11, it can be attracted by the corresponding magnetic block.

[0039] In this design, the operator first places the first bracket B on top of the second magnetic block 12 through the cooperation of the through hole B3 and the protrusion 121. The cooperation of the protrusion 121 and the through hole B3 can restrict the horizontal movement of the first bracket B and also provide an adsorption force to ensure the stability of the first bracket B. Then, the outer baffle A is placed on the first magnetic block 11 with its plate surface A4 in a vertical position, and the horizontal movement of the outer baffle A is restricted by at least two vertically arranged first positioning posts 131. At this time, the plate surface A4 of the outer baffle A is in contact with the first bracket B, and the second positioning post 111 is adjacent to the plate surface A4 of the outer baffle A. Then, according to the position of the second positioning post 111, the second bracket C is placed on the second positioning post 111, so that the second bracket C is in contact with the plate surface A4 of the outer baffle A. At this time, the positioning of all accessories is completed, and welding operations can be carried out.

[0040] In this way, magnetic blocks are used to precisely position the outer baffle A and the first bracket B and the second bracket C that need to be welded to the outer baffle A. The magnetic force provided by the magnetic blocks can maintain the relative relationship of each accessory even after the hand is removed, ensuring precise positioning.

[0041] Furthermore, regarding the restriction of the horizontal movement of the outer baffle A by two first positioning posts 131, the outer baffle A has mounting plates A1 on both sides along its length direction, and mounting holes A2 on the mounting plates A1. The axis of the mounting holes A2 extends along the width direction of the outer baffle A. The number of first positioning posts 131 matches the number of mounting holes A2 on one side of the outer baffle A. When the plate surface A4 of the outer baffle A is in a vertical state, the axis of the mounting holes A2 is in a vertical state, and the first positioning posts 131 pass through the mounting holes A2 on one side of the outer baffle A, thus restricting the horizontal movement of the outer baffle A.

[0042] Specifically, the mounting plate A1 and mounting hole A2 on the outer baffle A are existing technologies in this field. In the technical solution disclosed in Chinese Patent CN213007598U, the bolt hole is the mounting hole A2 in this embodiment. Therefore, regarding the positioning of the outer baffle A, the mounting hole A2 on one side of the outer baffle A cooperates with the first positioning post 131. That is, when the outer baffle A is in a vertical state with its plate surface A4, the axis of the mounting hole A2 is also in a vertical state. The outer baffle A is placed on the first magnetic block 11 in this state so that the mounting hole A2 on one side corresponds to the position of the first positioning post 131. The first positioning post 131 passes through the mounting hole A2 on one side of the outer baffle A, and the horizontal movement of the outer baffle A is restricted by fixing a straight line at two points.

[0043] Among them, reference Figure 4 and Figure 5 The direction along the length of the outer baffle A is the y-direction of the coordinate axis in the figure, and the direction along the width of the outer baffle A is the z-direction of the coordinate axis in the figure.

[0044] It should also be noted that, regarding the way the outer baffle A is in a vertical position with its plate surface A4, it is necessary to ensure that the plate surface A4 of the outer baffle A faces the second magnetic block 12. The plate surface A4 means the side facing outward after the heat sink assembly is completed.

[0045] Preferably, the welding positioning fixture for the outer baffle assembly further includes two third magnetic blocks 13, two first positioning posts 131, and two first positioning posts 131 located on the two third magnetic blocks 13 respectively. The two third magnetic blocks 13 are arranged at intervals on the base plate 1, two first magnetic blocks 11 are located between the two third magnetic blocks 13, and two second magnetic blocks 12 are located between the two first magnetic blocks 11. When the outer baffle A is placed on the first magnetic block 11, the outer baffle A simultaneously contacts the two second magnetic blocks 12.

[0046] In practical applications, by setting the first positioning post 131 on the third magnetic block 13, and through the adsorption effect of the third magnetic block 13 and the limiting effect of the first positioning post 131 passing through the mounting hole A2, the stability of the outer baffle A can be further ensured. After all the accessories are placed in the fixed position, even without hand assistance, the accessories will not shift due to the adsorption effect of the magnetic blocks. The positional relationship between the first magnetic block 11, the second magnetic block 12, and the third magnetic block 13 is determined solely by the position of each accessory on the outer baffle A. If the position of each accessory on the outer baffle A changes, the positions of the first magnetic block 11, the second magnetic block 12, and the third magnetic block 13 will also change accordingly.

[0047] In this embodiment, both ends of the outer baffle A along its length direction are provided with bent portions A3 that bend away from the plate surface A4. The bottom plate 1 is also provided with two fourth magnetic blocks 14. The two fourth magnetic blocks 14 are arranged at intervals on the bottom plate 1 and match the positions of the two bent portions A3. The two third magnetic blocks 13 are located between the two fourth magnetic blocks 14. When the outer baffle A is placed on the first magnetic block 11, the outer baffle A is in contact with the two second magnetic blocks 12 and the two fourth magnetic blocks 14 at the same time.

[0048] Regarding the bent portion A3 on the outer baffle A, it is mainly used to adapt to the structure of the radiator and is customized according to customer requirements. In order to adapt to the bent portion A3 on the outer baffle A, this embodiment adopts the method of adding magnetic blocks. By adding a fourth magnetic block 14, the setting position of the fourth magnetic block 14 matches the position of the bent portion A3. The function of the fourth magnetic block 14 is to support the bent portion A3. If the fourth magnetic block 14 is just a support block without the adsorption function, it can also support the bent portions A3 at both ends of the outer baffle A. The adsorption function of the fourth magnetic block 14 is to ensure the integrity of the tooling. At the same time, because the middle part of the outer baffle A is supported by the first positioning post 131, the first magnetic block 11, and the third magnetic block 13, if the worker accidentally applies a horizontal force to the bent portion A3 of the outer baffle A, the bent portion A3 is easily deformed. Therefore, the fourth magnetic block 14 is set to have an adsorption function to further ensure the safety of the outer baffle A.

[0049] In this embodiment, gaps 15 are provided between each pair of adjacent magnetic blocks 11, 12, 13 and 14.

[0050] In practical use, gaps of 15 are directly applied to parts that do not require positioning and support to control costs; at the same time, while ensuring accurate positioning, the magnetic attraction force of the outer baffle A is reduced, making it easier to remove the outer baffle A after welding.

[0051] The first positioning post 131 on the third magnetic block 13, the protrusion 121 on the second magnetic block 12, and the second positioning post 111 on the second magnetic block 12 can all be achieved by welding.

[0052] In this embodiment, the first support B has an L-shaped structure. The first support B includes a first horizontal part B1 and a first vertical part B2, which are integrally formed. A through hole B3 is located on the first horizontal part B1. The through hole B3 is a strip-shaped through hole B3, and the end of the through hole B3 away from the first horizontal part B1 is open. The protrusion 121 matches the structure of the through hole B3. When the first support B is placed on the top of the second magnet 12, the first vertical part B2 faces downward, and the side wall of the first vertical part B2 is in contact with the plate surface A4 of the outer baffle A.

[0053] Specifically, the strip-shaped through hole B3 on the first bracket B and the open design of the end of the through hole B3 away from the first horizontal part B1 are used for positioning pipes or lines. When the first bracket B is positioned, the first bracket B overlaps the top of the second magnetic block 12 through the first horizontal part B1, and ensures that the protrusion 121 cooperates with the through hole B3, so that its first vertical part B2 faces downward. The irregular structure of the protrusion 121 can restrict the first bracket B from moving in the horizontal direction. Without the assistance of the hand, the adsorption force of the second magnetic block 12 can ensure the stability of the first bracket B and ensure that the first vertical part B2 of the first bracket B is in contact with the plate surface A4 of the outer baffle A.

[0054] Furthermore, the second bracket C has an L-shaped structure. The second bracket C includes a second horizontal part C1 and a second vertical part C2. The second horizontal part C1 and the second vertical part C2 are integrally formed. The second horizontal part C1 is provided with a connecting hole, which matches the second positioning post 111. When the second bracket C is placed on the first magnetic block 11, the second positioning post 111 passes through the connecting hole, and the side wall of the second vertical part C2 is in contact with the plate surface A4 of the outer baffle A.

[0055] Specifically, the second bracket C is existing technology in this field and is also described in the technical solution disclosed in Chinese Patent CN202518088U, in which the side plate accessory 1 is the second bracket C in this embodiment.

[0056] Regarding the positioning of the second bracket C, the first bracket B and the outer baffle A have already been placed on the second bracket C. At this time, the through hole B3 on the second horizontal part C1 of the second bracket C is matched with the second positioning post 111, and the second bracket C is attracted by the first magnetic block 11 to complete the positioning of the second bracket C. Since the outer baffle A has already been placed on the first magnetic block 11, the second bracket C has only one installation method, that is, the second vertical part C2 is attached to the plate surface A4 of the outer baffle A.

[0057] In a preferred embodiment, the first magnetic block 11, the second magnetic block 12, the third magnetic block 13, and the fourth magnetic block 14 are all magnetic blocks; in other embodiments, the first magnetic block 11, the second magnetic block 12, the third magnetic block 13, and the fourth magnetic block 14 are blocks with a magnetic layer on top.

[0058] When the first magnetic block 11, the second magnetic block 12, the third magnetic block 13 and the fourth magnetic block 14 are blocks with a magnetic layer on top, the magnetic layer is a magnetic block, and the magnetic block can be fixed to the block by welding or bonding. The block can be a stainless steel block or an iron block.

[0059] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of this application, and these improvements or modifications should also be considered within the scope of protection of this application.
