Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a front grille assembly testing device. Background Technology

[0002] The front grille assembly is a core component of a vehicle's front fascia, integrating multiple functions such as heat dissipation, aerodynamics, brand logo display, and providing openings for sensors in advanced driver assistance systems (ADAS) such as radar and cameras. Its manufacturing quality directly impacts the overall vehicle's appearance, heat dissipation efficiency, and the reliability of the ADAS system. Therefore, rigorous quality testing of the front grille assembly before it leaves the factory is crucial.

[0003] For example, Chinese patent "CN220007445U" discloses a "contouring fixture for inspecting automotive front grilles." This fixture, through the cooperation of its various components, allows the front grille body to be initially fixed after being placed into the inspection slot. Then, the fixing assembly further secures the grille body through the cooperation of other components. The fixing method is simple and quick, improving installation efficiency. However, the inspection slot structure of the aforementioned fixture is fixed and can only accommodate the installation of one type of front grille. For the inspection of batches of different models of front grilles, different fixtures need to be customized and replaced accordingly, which not only increases costs but also wastes time. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a front grille assembly testing device, which solves the problem that different clamps are required for installing different front grilles in existing technologies.

[0005] According to the embodiments of this utility model, the following technical solution is adopted:

[0007] Located on the base of the testing box;

[0008] The support frame consists of two support frames located on both sides of the base, each with two slidably mounted support blocks.

[0009] An adjustment component, located on the base and connected to two support frames, is used to synchronously move the two support frames along the length of the base to adjust the distance between the two support frames.

[0010] Preferably, the adjustment component includes:

[0011] The gear is rotatably located inside the base.

[0012] Two racks are respectively installed on both sides of the base and mesh with gears, and are respectively connected to two support frames.

[0013] Preferably, the testing box is provided with a slide rail along the length of the base, and the bottom of the support frame is provided with a slider, which is slidably mounted on the slide rail.

[0014] Preferably, the base is threaded with a compression bolt, the end of which abuts against the side of one of the racks.

[0015] Preferably, it also includes an adjusting screw rotatably mounted on the support frame and a threaded block connected to the support block, the threaded block being threadedly connected to the adjusting screw.

[0016] Preferably, the support block is recessed downward to form a limiting groove.

[0017] Preferably, the bottom of the support frame is provided with a connecting rib, and the end of the connecting rib is connected to the rack.

[0018] Preferably, the base is provided with positioning posts, and the grille body is fitted onto the positioning posts.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In this solution, by adjusting the components, two support frames can be driven to move synchronously in opposite directions, thereby dynamically adjusting the spacing between the support frames and making it suitable for the installation of grid bodies of different lengths. Moreover, the support blocks are used to support the grid bodies, and the position of the support blocks on the support frames can be slidable according to usage requirements, making it suitable for the installation of grid bodies of different widths. This solution can adapt to grid bodies of different lengths and widths without the need to customize special clamps for each type of grid body. Attached Figure Description

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0027] In the contour jig disclosed in CN220007445U, because the detection slot is a fixed slot structure, only a specified model of grille body 3 can be installed. Therefore, in the detection operation of other grille bodies 3, it is necessary to change to other contour jigs. This involves additional jig mold making, processing and debugging, which undoubtedly increases the cost. At the same time, it is also necessary to debug and install for different grille bodies 3, which wastes time. Therefore, this utility model embodiment proposes a front grille assembly detection device for installing grille body 3, including a detection box 1 and a detector 2 slidably disposed in the detection box 1. The detection device also includes:

[0028] The base 4 is located on the test box 1;

[0029] Support frame 5, two support frames 5 are located on both sides of the base 4, and each is slidably provided with two support blocks 9;

[0030] An adjustment component is located on the base 4 and connected to two support frames 5, which is used to synchronously move the two support frames 5 along the length of the base 4 to adjust the distance between the two support frames 5.

[0031] In the embodiments of this utility model, such as Figures 1 to 3As shown, the base 4 is fixedly installed on the table surface of the inspection box 1. The detector 2 is a vision sensor, and its electrical connection with the controller is a conventional technology. By driving the detector 2 to slide along the length of the inspection box 1, the entire table surface area can be scanned and inspected. Two support frames 5 are located on both sides of the base 4, and the two support frames 5 can slide on the table surface of the inspection box 1. With the cooperation of the adjustment component, the two support frames 5 can be driven to move synchronously towards each other or away from each other. The spacing of the support frames 5 can be dynamically adjusted according to the grid body 3 to be installed, thus accommodating the installation of grid bodies 3 of different lengths. If the grid body 3 is replaced later, only the spacing of the two support frames 5 needs to be adjusted again accordingly. The support blocks 9 of the support frames 5 can support the grid body 3 to ensure the stability of the grid body 3 during inspection. At the same time, the way the grid body 3 is laid flat on the support frames 5 also facilitates the inspection of the grid body 3 by the detector 2, such as cracks and holes. Meanwhile, the position of the sliding support block 9 on the support frame 5 can be adjusted according to usage requirements, making it suitable for installation of grille bodies 3 of different widths. This solution can be adapted to grille bodies 3 of different lengths and widths, eliminating the need to customize special clamps for each type of grille body 3. This not only saves upfront costs but also eliminates the need to replace other auxiliary tools, saving time.

[0032] Based on the above scheme, in order to simplify the adjustment steps, such as Figure 4 As shown, the adjustment components include:

[0033] Gear 10 is rotatably located inside the base 4;

[0034] Two racks 1001 are respectively installed on both sides of the base 4 and mesh with the gear 10, and are respectively connected to two support frames 5.

[0035] Gear 10 is rotatably mounted on base 4 so that it can rotate. Two racks 1001 are both mounted on base 4 and mesh with gear 10. When gear 10 rotates, it can synchronously drive the two racks 1001. However, gear 10 is not used as a driving source. Therefore, when adjusting the position of the two support frames 5, pushing or pulling one of the support frames 5 causes this support frame 5 to drive the rack 1001 connected to it to move. At the same time, this rack 1001 drives gear 10 to rotate. The rotation of gear 10 drives the other rack 1001 to move on base 4, realizing the synchronous adjustment of the two support frames 5, which is more convenient. Since there is a gap between the rack 1001 and the base 4, and the support frame 5 is easily moved by external forces, the base 4 is threaded with a clamping bolt 8. The end of the clamping bolt 8 abuts against the side of one of the racks 1001. After adjusting the position of the two racks 1001, by rotating the clamping bolt 8, the end of the clamping bolt 8 abuts against the side of the corresponding rack 1001, and the rack 1001 is fixed by friction, so that the rack 1001 cannot move, thereby realizing the limiting fixation of the two support frames 5 and ensuring the stability of the two support frames 5 after adjustment.

[0036] Specifically, such as Figure 1 As shown, the test box 1 is provided with a slide rail 7 along the length of the base 4, and the bottom of the support frame 5 is provided with a slider 701. The slider 701 is slidably disposed on the slide rail 7. With the cooperation of the slide rail 7 and the slider 701, the radial force brought by the support frame 5 on the rack 1001 can be borne, so as to avoid the rack 1001 from deforming due to force and improve its service life.

[0037] Based on the above scheme, the adjustment of the support block 9 on the support frame 5 can be achieved through friction, that is, there is friction between the support block 9 and the groove of the support frame 5. After sliding adjustment of the support block 9, it can achieve self-fixation under the action of friction. However, in order to ensure the stability of the support block 9 after adjustment, the adjustment method can also be the adjustment screw 6, such as... Figure 3As shown, it also includes an adjusting screw 6 rotatably mounted on the support frame 5 and a threaded block 601 connected to the support block 9. The threaded block 601 is threadedly connected to the adjusting screw 6. The threads at both ends of the adjusting screw 6 have opposite directions of rotation. Therefore, when the adjusting screw 6 is rotated, the two threaded blocks 601 on the adjusting screw 6 can move towards each other or away from each other, thereby making the distance between the two support blocks 9 smaller or larger. This allows the two support blocks 9 to be better supported on the support points of the grille body 3. The support points can be the inner side of the grille body 3 or the positioning pin of the grille body 3. Therefore, in order to ensure the stability of the support block 9 in supporting the grille body 3, the support block 9 is recessed downward to form a limiting groove 901, so that the positioning block, positioning pin, or edge of the grille body 3 can be directly engaged in the limiting groove 901, ensuring the stability of the grille body 3 on the support block 9.

[0038] Specifically, such as Figure 4 As shown, the bottom of the support frame 5 is provided with a connecting rib 501, and the end of the connecting rib 501 is connected to the rack 1001. By setting the connecting rib 501, the support of the support frame 5 can be increased, ensuring the structural strength of the support frame 5 and preventing deformation.

[0039] Specifically, in some embodiments, such as Figures 1 to 3 As shown, the base 4 is provided with a positioning post 401, and the grille body 3 is sleeved on the positioning post 401. The positioning post 401 is threaded to the base 4. For the grille body 3 with the car logo hole in the middle, the hole can be sleeved on the positioning post 401 to play the role of positioning and installation.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
