[0002] Automotive parts refer to the consumable materials that make up the various units of a car and serve the car. They cover core components such as engines, transmission systems, and bodies, and are characterized by a wide variety and complex substitutes.
[0003] The front grille assembly is a crucial component of a car body, affecting not only the overall aesthetics but also functions such as engine cooling and aerodynamics. Therefore, it requires rigorous testing after production to ensure quality. Existing front grille assembly testing devices suffer from insufficient flexibility in adjusting the position of the testing components, making it difficult to adapt to different grille assemblies. This limits the testing range, preventing comprehensive coverage of all grille testing areas and impacting testing effectiveness and efficiency. Furthermore, they often suffer from poor positioning stability, easily damaging the grille surface due to excessive pressure during positioning, thus lacking practicality. Therefore, a new testing device for the front grille assembly needs to be designed to address these issues. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Reference Figure 1-5 A testing device for an automotive front grille assembly includes a testing platform 1. Two electric push rods 3 are fixedly mounted on the upper surface of the testing platform 1 via a support plate 2. The telescopic ends of the two electric push rods 3 are slidably connected to two sliding rods 5 via a movable plate 4. A limit plate 6 is fixedly mounted on one end of each sliding rod 5. The outer walls of the two sliding rods 5 on the same side are connected to the outer wall of the movable plate 4 on the same side via a buffer mechanism. A protective pad 9 is fixedly mounted on the other end of the two sliding rods 5 on the same side via a positioning plate 8. A guide frame 10 is fixedly mounted on the upper surface of the testing platform 1. A toothed plate 11 is fixedly mounted on the outer wall of the guide frame 10. The interior of the guide frame 10 is... A slider 13 is slidably mounted on the guide mechanism. A first motor 15 is fixedly mounted on the upper end face of the slider 13 via a connecting plate 14. A gear 16 that meshes with a toothed plate 11 is fixedly mounted on the outer wall of the output shaft of the first motor 15. A screw 18 is rotatably mounted on the upper end face of the connecting plate 14 via a support frame 17. A second motor 19 connected to the screw 18 is fixedly mounted on the upper end face of the support frame 17. A moving block 21 is rotatably mounted on the outer wall of the screw 18 via a limiting mechanism. A mounting plate 23 is fixedly connected to the outer wall of the moving block 21 via a connecting mechanism. An industrial camera 24 and two fill lights 25 are fixedly mounted on the bottom wall of the mounting plate 23.
[0017] Furthermore, the support plate 2 is vertically fixed on both sides of the upper surface of the testing table 1, which can provide stable support for the electric push rod 3. The protective pad 9 is made of flexible material and fits the outer wall contour of the grid, which can reduce frictional damage to the grid surface during positioning. The guide frame 10 is set along the length of the testing table 1 to ensure that the sliding path of the slider 13 is adapted to the grid testing area.
[0018] The buffer mechanism includes a buffer spring 7 installed on the outer wall of the slide bar 5. The two ends of the buffer spring 7 are elastically connected to the outer wall of the moving plate 4 and the inner wall of the limiting plate 6, respectively.
[0019] Furthermore, the buffer spring 7 allows the slide bar 5 to remain extended in its natural state, ensuring that the initial position of the positioning plate 8 is convenient for the operator to place the grille. The connection between the two ends of the buffer spring 7 and the moving plate 4 and the limiting plate 6 adopts a tight fixing structure to prevent detachment or displacement during long-term use.
[0020] The guiding mechanism includes a prismatic rod 12 fixedly installed inside the guide frame 10, and the prismatic rod 12 slides through the slider 13.
[0021] Furthermore, the axis of the prismatic rod 12 is aligned with the length direction of the guide frame 10, and its prismatic cross-section can effectively prevent the slider 13 from rotating during sliding, ensuring that the slider 13 drives the connecting plate 14 and subsequent components to always maintain a horizontal movement.
[0022] The limiting mechanism includes a limiting rod 20 fixedly installed inside the support frame 17, and the limiting rod 20 slides through the moving block 21.
[0023] Furthermore, the limiting rod 20 is arranged parallel to the screw 18 and symmetrically distributed on both sides of the screw 18, which can precisely limit the movement direction of the moving block 21 and prevent the moving block 21 from deviating from the preset movement trajectory as the screw 18 rotates.
[0024] The connecting mechanism includes a connecting rod 22 fixedly installed on the outer wall of the movable block 21, and the end of the connecting rod 22 is fixedly connected to the upper surface of the mounting plate 23.
[0025] Furthermore, the connecting rod 22 is vertically fixed on the side of the moving block 21 near the mounting plate 23, and the connection between the connecting rod 22 and the mounting plate 23 is fixed by welding.
[0026] A controller 26 is fixedly installed on the outer wall of the testing table 1. The controller 26 is electrically connected to two electric actuators 3, a first motor 15, a second motor 19, an industrial camera 24, and two supplementary lights 25.
[0027] Furthermore, the controller 26 is equipped with operation buttons and a display panel on its surface, which can display the working status of each component in real time. The controller 26 is also equipped with a signal processing module, which can receive the detection data fed back by the industrial camera 24 and perform preliminary analysis, so that the operator can obtain the detection results in a timely manner.
[0028] In use, the front grille assembly of the car to be tested is first placed on the upper surface of the testing platform 1. The controller 26 activates two electric push rods 3, causing the telescopic ends of the push rods 3 to push the moving plate 4 towards the grille. The moving plate 4 then moves the sliding rod 5, which is slidably connected to it, synchronously. This causes the positioning plate 8 at the end of the sliding rod 5 to approach the grille until the protective pad 9 on the positioning plate 8 is in close contact with the outer wall of the grille. As the moving plate 4 is further pushed, the sliding rod 5 slides relative to the moving plate 4. The buffer spring 7, sleeved on the outer wall of the sliding rod 5, is stretched and generates a buffering force, preventing excessive positioning pressure from damaging the grille surface. Damage is removed, and the grid is stably clamped on the inspection table 1 to complete the positioning and fixing of the grid. After positioning, according to the inspection requirements of the grid, the first motor 15 is started by the controller 26. The output shaft of the first motor 15 drives the gear 16 to rotate. Since the gear 16 meshes with the toothed plate 11 on the outer wall of the guide frame 10, when the gear 16 rotates, it drives the slider 13 to slide along the prismatic rod 12 inside the guide frame 10. The slider 13 drives the connecting plate 14, the support frame 17 and the industrial camera 24 on the mounting plate 23 to move along the length direction of the grid, and adjusts the industrial camera 24 to the horizontal position of the grid to be inspected. If the height of the industrial camera 24 needs to be adjusted to accommodate grilles of different thicknesses or specifications, the second motor 19 is started via the controller 26. The second motor 19 drives the screw 18 inside the support frame 17 to rotate. The moving block 21, restricted by the limit rod 20, cannot rotate with the screw 18 and can only move up and down along the axis of the screw 18. The moving block 21 drives the mounting plate 23 and the industrial camera 24 to adjust their height via the connecting rod 22 until the industrial camera 24 is precisely aligned with the part of the grille to be inspected. Then, the two supplementary lights 25 and the industrial camera 24 are started via the controller 26. The supplementary lights 25 provide sufficient and uniform illumination for the inspection area to avoid insufficient light affecting the inspection effect. The industrial camera 24 takes pictures to inspect the appearance defects of the grille and the accuracy of the mounting hole positions. During the inspection process, if it is found that other areas need to be inspected, the electric push rod 3, the first motor 15 or the second motor 19 can be adjusted again via the controller 26 to flexibly adjust the grille positioning state or the inspection position of the industrial camera 24 to ensure comprehensive and accurate inspection of all parts of the grille.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
