Description

Technical Field

[0001] The invention relates to the technical field of radiator core testing, in particular to a balance testing device for an automobile radiator core. Background Art

[0002] The radiator core is the core component of the radiator, usually composed of copper tubes, aluminum fins, copper heads and heads, among which: The copper tube is the main pipeline of the core, and the internal fluid circulation is carried out through the copper tube. The aluminum fin is the main heat dissipation part of the core, which is connected to the copper head through the copper tube to transfer the heat to the radiator surface. The copper head and the head are used to fix the core and connect the radiator. The working principle of the radiator core is to transfer the heat of the heating element to the radiator surface through the fluid circulation inside the core, thereby reducing the temperature. Specifically, the fluid circulating through the copper tube absorbs heat in the high temperature area, and then transfers the heat to the radiator surface through the aluminum fins, so that the heat can be dissipated into the air. As the fluid continues to circulate, the heat will be continuously transferred to the radiator surface, thereby achieving the heat dissipation effect. The automobile radiator core is often placed at the front end of the engine, close to the front bumper or front grille. This layout helps to ensure that the radiator can effectively contact the outside air, thereby achieving efficient heat exchange.

[0003] Before the automobile radiator core is put into use, it is necessary to undergo a thermal balance test and a balance test. The purpose of the thermal balance test is to verify whether the heat exchange efficiency of the radiator core meets the design requirements, while the balance test is a balance test for the air guide and exhaust on the windward side of the radiator core.

[0004] There are few existing balance test processes for automobile radiator cores before installation and use. Most of them are put into use directly after the process design before the production of the automobile radiator core, such as the layout of copper tubes or aluminum fins on the radiator core, but they do not combine the design characteristics of different automobile front structures, such as the front end position of the engine or the front grille position. As a result, the automobile radiator core manufactured according to a specific process has a large deviation in its own balance effect due to the adjustment of the installation position. Due to the lack of balance testing before installation and use, the automobile radiator core is very prone to balance deviation during use. For example, the exhaust effect is reduced, a large wind resistance is generated, and the automobile radiator core is deformed, and its service life is greatly reduced. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a balance testing device for an automobile radiator core, so as to fundamentally solve the problem that most of the current automobile radiator cores are directly put into use after the process design before production, and lack of balance testing before installation and use, which leads to the problem that the automobile radiator core is very easy to have balance deviation during use.

[0024] During the specific implementation, the operator can first lift the box cover 13 through the handle provided on the box cover 13, and support it through the support frame 14, and then install the automobile radiator core to be tested on the clamping component 4 according to the preset assembly angle, wherein the preset assembly angle can be the transfer position and angle of the subsequent automobile radiator core installed at the front end of the vehicle, which has achieved the restoration of the scene and ensured the accuracy of the subsequent test data. As for the installation of the automobile radiator core on the clamping component 4, specifically, a wind resistance test is first performed, and the operator can drive the linkage frame 43 and the clamping part 44 to rotate toward the direction of the inclination test piece through the first movable shaft 42 according to the preset assembly angle, and move to In terms of the preset assembly angle, in some optional embodiments, the first movable shaft 42 can be a lockable movable shaft. It can be understood that after rotating to the specified angle, the operator can lock the movable shaft through the lock buckle set in its axial direction or circumferential direction to ensure the stability of the movable shaft after adjustment. The lockable movable shaft is understandable to those skilled in the art and will not be elaborated on here. Afterwards, the operator can overlap the two sides of the automobile radiator core on the clamping part 44 respectively, and rotate the fastening part 45 clockwise to make it move toward the direction of the automobile radiator core inside the clamping part 44, so as to achieve the abutment against the automobile radiator core and complete the clamping operation. The installation is convenient and quick, and is suitable for thick In addition, in some optional embodiments, in order to ensure the adaptability of the wind resistance test piece to automobile radiator cores of different sizes, the linkage frame 43 can be designed as a telescopic adjustable structure to adjust the distance between the first movable shaft 42 and the clamping portion 44, so that subsequent operators can adjust the length of the linkage frame 43 according to the length of the automobile radiator core, thereby improving the adaptability of the wind resistance test piece to the automobile radiator core. Afterwards, the operator can adjust the position of the fan assembly 5 on the adjustment stand assembly 3 according to the size and direction of the blast, and the adjustment operation includes moving the longitudinal sliding table 34 along the trajectory of the first slide slot 33 toward or away from the clamping The component 4 slides in the direction to ensure that the wind force generated by the subsequent fan component 5 can be accurately focused on the surface of the automobile radiator core, and the horizontal sliding platform 54 drives the fan component 5 to slide horizontally along the trajectory of the second slide groove 35 to adjust the relative position of the fan component 5 and the automobile radiator core on the clamping component 4. After that, the operator closes the box cover 13 and opens the fan component 5 through the controller to perform a blast operation on the automobile radiator core on the clamping component 4. In some optional embodiments of the present invention, the controller can be set at any position on the balance test device of the automobile radiator core that is convenient for the operator to operate, and the controller can be an MCU (Microcontroller Unit;A microcontroller unit) chip is used to realize the overall control of the balance test device of the automobile radiator core through the MCU chip, wherein the controller is electrically connected to the balance test device of the automobile radiator core, and the electrical connection includes a wired connection and a wireless connection, and the wireless connection method includes but is not limited to Bluetooth connection, WiFi, IF radio frequency, zigbee, and the wired connection method includes but is not limited to a USB line connecting the balance test device of the automobile radiator core to the controller. Then, the controller controls the fan assembly 5 to turn on. At the same time, in some optional embodiments, any sliding component on the adjustment stand assembly 3 can be electrically driven or manually adjusted to slide. The operator can also control the fan assembly 5 on the adjustment stand assembly 3 through the controller to move it to a specific position to wait for it to be turned on and used. The number of fans 53 can be one, and it fully covers the area of ​​the fan rack 51, reducing the output error caused by adjacent gaps when the four fans 53 work at the same time. After that, The surface of the automobile radiator core is blown by the fan 53. It should be noted that the wind speed generated by the vehicle speed of 0km / h~100km / h can be simulated by the fan 53. During the process, the pressure value of the wind resistance test piece is fed back in real time by the elastic member in the slide groove on the fixed frame 41, so as to finally determine the resistance value of 0km / h~100km / h of the automobile radiator core to be tested in the simulated scene. After that, the operator can compare the resistance value tested with the resistance value of the preset standard, and finally determine whether the wind resistance of the automobile radiator core to be tested meets the standard requirements. It should be noted that due to the different models and sizes of the automobile radiator core to be tested, there are preset standard resistance values ​​corresponding to the current automobile radiator core to be tested in the industry. For common knowledge, the resistance value is not specifically described here. In addition, through this application, the scene restoration can be implemented in combination with the installation position of the current automobile radiator core to be tested at the front end of the vehicle during subsequent use, and the wind force value generated at various vehicle speeds during use, so as to improve the accuracy of the final test data. ;

[0025] Furthermore, before performing the inclination test on the automobile radiator core to be tested, the operator can replace the assembly position of the automobile radiator core to be tested, and install the automobile radiator core to be tested on the inclination test piece. Specifically, the operator can place the automobile radiator core to be tested at the bottom of the fixing plate 48 and fit it with the bottom, and then rotate the adjusting shaft 49 to drive the bottom clamping plate 410 to move toward the inner automobile radiator core to be tested. The rotation between the adjusting shaft 49 and the clamping plate 410 can be driven by a middle gear and parallel racks distributed on both sides of the gear, and the gear is installed in the axial direction of the adjusting shaft 49, and the rack is fixed on the clamping plate 410, and the above transmission relationship is a common mechanical transmission in the mechanical field. Finally, the clamping plate 410 clamps the inner automobile radiator core to be tested. Then, the operator can open the fan assembly 5 after closing the box cover 13 to blow air to the automobile radiator core to be tested on the inclination test piece, and simulate the wind speed condition of 0km / h~100km / h. In addition, in order to meet the position simulation of the automobile radiator core to be tested being subsequently assembled on the front end of the vehicle, the fan 53 and the fan frame 51 can also be set as an active connection. The operator can adjust the inclination of the fan 53 on the fan frame 51 to restore the windward surface of the automobile radiator core to be tested for testing. During the process, the activity status information of the second active shaft 47 is obtained in real time. In some optional embodiments, the second active shaft 47 can be a universal shaft. , its range of motion is on the X-axis and Y-axis. Considering that there may be wind resistance in the Z-axis direction, the second movable axis 47 is limited in motion in the Z-axis direction, and an angle sensor is arranged inside. The angle sensor, also known as an angular displacement sensor or an angular transducer, is a sensor for detecting angles. It uses sensitive elements (such as Hall elements, capacitive sensors, photoelectric sensors, etc.) to sense the position changes of rotating bearings. When the object rotates, the signals detected by the sensitive elements also change accordingly. After being processed by the signal processing circuit, these signals are finally output to the corresponding control system in the form of digital or analog signals, thereby realizing accurate measurement and control of the rotation angle to obtain the current The inclination direction and specific inclination angle of the automobile radiator core to be tested before. It should be noted that if the current automobile radiator core to be tested is qualified, the second movable shaft 47 will not have an angle deviation. In some optional embodiments, in order to avoid test errors, the activity angle of the second movable shaft 47 less than or equal to 5° can be determined to be qualified. In addition, in some optional embodiments of the present invention, the four fans 53 can be independently controlled, and the four fans 53 and the second movable shaft 47 can be electrically connected. In the subsequent inclination test stage, at least one fan 53 opposite to the inclination direction of the second movable shaft 47 can be shut down according to the inclination direction fed back by the second movable shaft 47, and the angle change of the second movable shaft 47 can be obtained in real time to determine whether the second movable shaft 47 has returned to the state as shown in the figure. Figure 5If it is the normal state shown, then the unqualified area of ​​the automobile radiator core is determined according to the coverage area of ​​the shut down fan 53. The purpose is to implement a regional screening test on the automobile radiator core to be tested, so that subsequent operators can accurately locate the unqualified area on the automobile radiator core according to the shut down fan 53 area.

[0026] In summary, the balance test device for the automobile radiator core in the above-mentioned embodiment of the present invention can respectively perform wind resistance test and inclination test on the automobile radiator core through the wind resistance test piece and the inclination test piece arranged on the clamping component 4, and the constructed test scene is based on the test box 1, and the wind speed under different vehicle speeds is simulated by the fan component 5, and the automobile radiator core to be tested clamped on the wind resistance test piece or the inclination test piece is subjected to a blast test, so as to collect whether the automobile radiator core to be tested has an inclination during the blasting process or the displacement distance and displacement resistance value caused by the change of wind resistance, judge whether the current automobile radiator core is qualified, ensure the quality of the automobile radiator core, and solve the problem that most of the automobile radiator cores are directly put into use based on the process design before the production of the automobile radiator core, and lack of balance test before installation and use, which leads to the problem that the automobile radiator core is very easy to have balance deviation during use.
