Description

Technical Field

[0001] The utility model relates to the technical field of radiator core repair, in particular to a radiator core repair tool. Background Art

[0002] The radiator core is usually composed of flat tubes and wavy heat dissipation belts. The flat tubes and the heat dissipation belts are installed alternately and then welded together by brazing. The flat tubes are parallel to each other. Coolant flows in the flat tubes, and the heat of the coolant is dissipated to the outside through the heat dissipation belts on the outside of the flat tubes.

[0003] Under the existing technology, a fully automatic radiator core assembly machine is generally used to assemble and produce radiator cores, and the production cycle is 44 seconds per piece. When it is found that the edge of the flat tube in the radiator core is damaged or bent and broken, the fully automatic radiator core assembly machine needs to be shut down to repair and replace the defective flat tube. At this time, the flat tube and the heat dissipation belt have not been brazed and fixed, so they can be freely pulled out and replaced. However, after the replacement is completed, the flat tube and the heat dissipation belt need to be clamped and brazed. Since there is no suitable clamping device in the factory, the clamping process needs to be completed on the fixture in the fully automatic radiator core assembly machine. Through the clamping of the above-mentioned fixture, the brazing fixture is fixed to the radiator core that has been repaired in the fixture. Since the automatic radiator core assembly machine is in a closed state at this time, this will extend the production cycle of the fully automatic radiator core assembly machine, reduce production efficiency, and delay the normal production of the radiator core.

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0018] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0020] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0021] Under the existing technology, when a problem occurs with the flat tube or the heat dissipation belt of the radiator core, it is necessary to use the clamp on the fully automatic radiator core assembly machine to clamp the repaired radiator core for brazing and fixation. Therefore, the entire replacement and repair process needs to be completed on the fully automatic radiator core assembly machine. In this way, the fully automatic radiator core assembly machine must be shut down and the fully automatic radiator core assembly machine can only be started again after the problematic flat tube or heat dissipation belt is replaced. This will cause the production cycle of the fully automatic radiator core assembly machine to be extended, thereby reducing production efficiency.

[0022] In order to solve the above problems, Figure 1 to Figure 2 As shown, the utility model provides a radiator core repair tool, which includes a workbench 1, a table top 11 is formed on the workbench 1, a fixed side plate 2 is installed on one side of the table top 11, and a movable side plate 3 is placed on the other side of the table top 11, and the radiator core 6 is placed on the table top 11, and the fixed side plate 2 and the movable side plate 3 are abutted on the opposite sides of the radiator core 6, and the movable side plate 3 moves perpendicular to the contact surface between the fixed side plate 2 and the radiator core 6, and the movable side plate 3 is connected to a pushing member, and the pushing member pushes the movable side plate 3 to move. When a radiator core 6 with quality problems is found, the radiator core 6 is taken out and placed on the table top 11, and then the main plates at both ends of the radiator core 6 are removed to facilitate the flexible extraction of the damaged flat tube or heat dissipation belt, and then the intact flat tube or heat dissipation belt is replaced, and the main plate is installed, and then the movable side plate 3 is moved so that the movable side plate 3 and the fixed side plate 2 clamp the radiator core 6 in the middle, and the fixed side plate 2 and The movable side plate 3 is provided with a plug-in slot 4, and the opening of the plug-in slot 4 faces the radiator core 6. The limiting part 51 of the brazing fixture 5 is inserted in the plug-in slot 4. The radiator core 6 pressed by the passive side plate 3 will be slightly smaller than the spacing between the limiting parts 51, which is convenient for the limiting parts 51 to be clamped on both sides of the radiator core 6. Thereafter, the movable side plate 3 is moved in the opposite direction, and the radiator core 6 restores its original size. The two sides of the radiator core 6 that are crimped will automatically abut against the limiting parts 51, so that the radiator core 6 is clamped by the limiting parts 51. The limiting parts 51 replace the crimping of the fixed side plate 2 and the movable side plate 3, so that the worker can move the radiator core 6 to the brazing process through the brazing fixture 5, and carry out the next step of processing, remove the damaged radiator core 6 from the fully-automatic radiator core assembly machine, replace and clamp it on the table 11, so that the fully-automatic radiator core assembly machine can continue to work without stopping, thereby ensuring production capacity.

[0023] At the same time, after the passive side plate 3 and the fixed side plate 2 of the radiator core 6 are clamped, the limit part 51 can be directly fixed on the same side of the dynamic side plate 3 and the fixed side plate 2 using the plug-in slot 4. After the dynamic side plate 3 is loosened, the limit part 51 can directly replace the clamping form of the dynamic side plate 3 and the fixed side plate 2, and the radiator core 6 can be transported to the next workstation, thereby improving the production capacity of the radiator core 6.

[0024] A positioning seat 7 is fixed on the workbench 1, and a fixed side plate 2 is detachably connected to the positioning seat 7. By replacing the fixed side plates 2 of different sizes, radiator cores 6 of different sizes can be adapted, thereby improving the adaptability of the radiator core repair tooling.

[0025] It should be particularly noted that a first through hole is provided on the positioning seat 7 of the utility model, and a first screw hole is provided on the thickness surface of the fixed side plate 2. The first bolt passes through the first through hole and is screwed into the first screw hole. The head of the first bolt is crimped on the positioning seat 7. The fixed side plate 2 is fixed to the positioning seat 7 by fastening with the first bolt. Other detachable connection methods can also be used, which are not limited to bolt connection methods.

[0026] The pushing member of the utility model includes a telescopic cylinder 8 and a telescopic rod. The telescopic cylinder 8 pushes the telescopic rod to move back and forth along the axis. A second screw hole is provided on the side of the telescopic rod close to the movable side plate 3. A second through hole is provided on the movable side plate 3. The second screw passes through the second through hole and is screwed into the second screw hole. By setting the second screw, the movable side plate 3 and the telescopic rod can be detachably connected. When facing radiator cores 6 of different sizes, the movable side plates 3 of different lengths can be replaced, so that the movable side plate 3 and the fixed side plate 2 of the utility model can clamp radiator cores 6 of different sizes, and the versatility is stronger. The telescopic cylinder 8 is pushed out along the axis of the telescopic rod, and then the movable side plate 3 is abutted against the radiator core 6, and the replaced radiator core 6 is clamped, replacing the clamping process on the fully automatic radiator core assembly machine, so that the process of replacing the flat tube can be completed outside the fully automatic radiator core assembly machine.

[0027] The telescopic cylinder 8 is slidably mounted on the track 9 , the length direction of the track 9 is perpendicular to the moving direction of the telescopic rod, and a positioning screw hole is provided on the side wall of the telescopic cylinder 8 , and the positioning bolt passes through the positioning screw hole and abuts against the track 9 .

[0028] At the same time, the telescopic cylinder 8 of the utility model is fastened to the track 9 by the positioning bolts. When the positioning bolts are unscrewed, the telescopic cylinder 8 can slide freely on the track 9 to change the position of the movable side plate 3, so that the crimping surface of the movable side plate 3 can be completely crimped on the radiator core 6. By adjusting the position of the movable side plate 3, the radiator core 6 is evenly stressed, so that the flat tube and the heat dissipation belt can be stably crimped.

[0029] The radiator core repair tool of the utility model also includes a placement groove, which is placed on one side of the workbench 1. Flat tubes are stored in the placement groove, so that workers can directly take out the flat tubes for direct replacement, so that the flat tube parts in the factory are placed more neatly and avoid being placed randomly.

[0030] The telescopic cylinder 8 of the utility model is an electric cylinder, which is electrically connected to a key switch 10. The key switch 10 is fixed to one side of the workbench 1. When the key switch 10 is pressed, the telescopic cylinder 8 controls the telescopic rod to extend, so that the movable side plate 3 presses the radiator core 6 onto the fixed side plate 2. Pressing the key switch 10 again will retract the telescopic rod, making it convenient for workers to take out the radiator core through the brazing fixture 5.

[0031] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
