Description

Technical Field

[0001] This utility model relates to the field of aluminum-plastic radiator processing, and in particular to a tooling for testing the air tightness of aluminum-plastic radiators. Background Technology

[0002] Aluminum-plastic radiators are a new type of composite radiator made of high-polymer environmentally friendly materials. The internal water pipes are made of non-metallic materials, while the exterior is made of aluminum alloy profiles. The heat dissipation strips are corrugated and fixed to the surface of the internal water channels for heat dissipation.

[0003] As a core component of heating and cooling systems, aluminum-plastic radiators need to withstand the flow of fluids such as water and antifreeze for extended periods. Air tightness is a key indicator that determines their safety performance, heat dissipation efficiency, and service life. Even minor leaks can lead to a drop in system pressure and heat dissipation failure, and may also cause pipe corrosion, equipment damage, or even safety hazards. Air tightness testing machines are essential quality inspection equipment.

[0004] Currently, when aluminum-plastic radiators are tested for air tightness using an air tightness testing machine, multiple testing heads are inserted into the radiator at once after it is placed on the workbench. After the test is completed, the testing heads are removed and placed on the table. This causes the testing heads to be easily crushed when the next aluminum-plastic radiator is placed on the workbench, resulting in damage and reduced work efficiency.

[0005] Therefore, it is necessary to provide an airtightness testing fixture for aluminum-plastic radiator processing to solve the above-mentioned technical problems. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First Embodiment

[0027] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the first embodiment of an airtightness testing fixture for aluminum-plastic radiator processing provided by this utility model;

[0028] Figure 2 for Figure 1 The diagram shows the structure of the lifting device. Figure 3 for Figure 2 The enlarged schematic diagram of part A is shown. A fixture for testing the airtightness of aluminum-plastic radiators includes: a testing device 1, a limiting frame 2, a lifting device 3, and a guiding device 6;

[0029] The limiting frame 2 is disposed inside the detection device 1;

[0030] The lifting device 3 includes a lifting component 31, a lifting plate 32, a telescopic component 33, and a movable frame 34. The lifting component 31 is fixedly installed on the top of the detection device 1. The top of the lifting plate 32 is fixedly installed on the output end of the lifting component 31. The telescopic component 33 is fixedly installed on the top of the lifting plate 32. One side of the movable frame 34 is fixedly installed on the output end of the telescopic component 33.

[0031] The guide device 6 is disposed inside the movable frame 34, and the guide device 6 is used to guide the movable frame 34.

[0032] The testing device 1 is a conventional air tightness testing machine used in the art. It is used by placing the heat sink on the operating table of the air tightness testing machine, inserting the testing head into the heat sink, and pulling out the testing head after the test is completed.

[0033] The lifting component 31 is a hydraulic rod, a cylinder, or an electric push rod, used to push the moving frame 34 to move after startup.

[0034] The lifting device 3 also includes a plurality of fixing members 35, which are respectively disposed inside the lifting plate 32 and the movable frame 34.

[0035] The fastener 35 is a bolt used to fix the detection head of the detection device 1 installed inside the movable frame 34 and the lifting plate 32.

[0036] When it is necessary to test radiators of different sizes, the test head can be removed by disassembling the fastener 35, replacing the lifting plate 32, and then reinstalling the test head.

[0037] The guiding device 6 includes a guide hole 61 and a guide rod 62. The guide hole 61 is opened inside the movable frame 34, and the guide rod 62 is slidably connected inside the guide hole 61.

[0038] One end of the guide rod 62 is fixedly installed on one end of the lifting plate 32. When the moving frame 34 moves, it drives the guide hole 61 to move to one side on the surface of the guide rod 62, thereby limiting the moving frame 34 and increasing the stability of the moving frame 34 when it moves.

[0039] The working principle of the airtightness testing fixture for aluminum-plastic radiator processing provided by this utility model is as follows:

[0040] When in use, the aluminum-plastic radiator is placed inside multiple limit frames 2.

[0041] After extending by activating the lifting component 31, the lifting plate 32 is pushed downward to allow multiple detection heads to be inserted into the aluminum-plastic radiator. Then, the telescopic component 33 is activated to retract, causing the moving frame 34 to move to one side, thereby allowing another detection head to be inserted into the aluminum-plastic radiator. The aluminum-plastic radiator is then inspected by multiple detection heads.

[0042] After the test is completed, the telescopic component 33 is activated to extend the mobile frame 34 and reset it.

[0043] At the same time, the lifting component 31 is activated to retract, which drives the lifting plate 32 to reset multiple detection heads.

[0044] Compared with related technologies, the airtightness testing fixture for aluminum-plastic radiator processing provided by this utility model has the following advantages:

[0045] This utility model provides an airtightness testing fixture for aluminum-plastic radiators. The limiting frame 2 limits the aluminum-plastic radiator, increasing its stability during testing. At the same time, the lifting device 3 is used to insert the testing heads of multiple testing devices 1 into the interior of the aluminum-plastic radiator, thereby facilitating and quickly inserting the testing heads into the interior of the aluminum-plastic radiator, increasing both the stability during testing and work efficiency.

[0046] Second Embodiment

[0047] Please refer to the following: Figure 4 and Figure 5 Based on the first embodiment of this application, which provides an airtightness testing fixture for processing aluminum-plastic radiators, the second embodiment of this application proposes another airtightness testing fixture for processing aluminum-plastic radiators. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0048] Specifically, the difference in the second embodiment of this application regarding the airtightness testing fixture for aluminum-plastic radiator processing is that it further includes an adjustment device 4 inside the testing device 1, and a sliding device 5 on the top of the adjustment device 4, the adjustment device 4 being used to adjust the position of the sliding device 5.

[0049] The adjusting device 4 is a double-headed hydraulic rod, which is used to move one end of the two sliding rods 51 after the double-headed hydraulic rod is activated.

[0050] The adjustment device 4 includes two adjustment slots 41, four adjustment blocks 42 and four limiting members 43. The two adjustment slots 41 are both opened inside the detection device 1. The four adjustment blocks 42 are slidably connected to the inside of the two adjustment slots 41 respectively. The four limiting members 43 are respectively disposed inside the four adjustment blocks 42.

[0051] The limiting component 43 is a bolt. The adjusting block 42 has a threaded hole that matches the bolt. When the bolt is rotated to one side, the bolt moves inside the threaded hole. When one end of the bolt contacts the inner wall of the adjusting groove 41, it limits the adjusting block 42. When one end of the bolt separates from the surface of the inner wall of the adjusting groove 41, the adjusting block 42 can move to one side, thereby adjusting the distance between the two sliding rods 51.

[0052] The sliding device 5 includes two sliding rods 51, multiple sliding blocks 52, and multiple positioning elements 53. The two ends of the two sliding rods 51 are respectively fixedly connected to one side of the four adjusting blocks 42. The multiple sliding blocks 52 are respectively slidably connected to the surfaces of the two sliding rods 51. The multiple positioning elements 53 are respectively disposed inside the multiple sliding blocks 52.

[0053] One side of each of the multiple limiting frames 2 is fixedly installed on one side of the multiple sliding blocks 52, which are used to adjust the position of the limiting frames 2 by means of the sliding blocks 52, so that the limiting frames 2 can limit the heat sinks of different sizes.

[0054] The positioning element 53 is a bolt, and the sliding block 52 has a threaded hole inside that is compatible with the bolt.

[0055] When the bolt is rotated to one side, the bolt moves inside the threaded hole. When one end of the bolt contacts the surface of the sliding rod 51, it limits the sliding block 52. When one end of the bolt separates from the surface of the sliding rod 51, the sliding block 52 can move to one side.

[0056] The working principle of the airtightness testing fixture for aluminum-plastic radiator processing provided by this utility model is as follows:

[0057] When it is necessary to adjust the limit frame 2, after the limit member 43 is loosened, the sliding rod 51 is moved to one side, which causes the two adjusting blocks 42 to move inside the two adjusting grooves 41 respectively. After the sliding rod 51 moves to the appropriate position, the limit member 43 is installed.

[0058] After releasing the positioning element 53, the sliding block 52 is moved to one side, causing the limiting frame 2 to move to one side. Once the limiting frame 2 has moved to the appropriate position, the positioning element 53 can be reset.

[0059] Compared with related technologies, the airtightness testing fixture for aluminum-plastic radiator processing provided by this utility model has the following advantages:

[0060] This utility model provides an airtightness testing fixture for aluminum-plastic radiator processing. The position of the limiting frame 2 is adjusted by adjusting device 4 in conjunction with sliding device 5, thereby facilitating the limiting of aluminum-plastic radiators of different sizes.

[0061] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
