[0031] like Figures 1 to 6As shown in the figure, this embodiment provides an inspection tool for automotive headlights. This inspection tool for automotive headlights includes a workbench 1, a bracket 2 fixedly connected to one side of the workbench 1, electric push rods 3 fixedly connected to both sides of the workbench 1, clamping components 4 fixedly connected to the output ends of the two sets of electric push rods 3, and a strength testing component 5 installed on the inner side of the bracket 2.

[0032] The clamping assembly 4 includes a clamping seat 401 located on the surface of the worktable 1. A compression spring 402 is installed inside the clamping seat 401. One end of the compression spring 402 is provided with a push rod 403. The end of the push rod 403 away from the compression spring 402 extends to the outside of the clamping seat 401. A clamping block 404 is provided on one side of the clamping seat 401. One end of the push rod 403 extends to the outside of the clamping seat 401 and is fixedly connected to the clamping block 404. Multiple sets of compression springs 402, push rods 403 and clamping blocks 404 are provided and are arranged at equal intervals. Two sets of clamping assemblies 4 correspond to each other, which can facilitate the clamping operation of vehicle lights. At the same time, the flexible clamping method of multiple sets of compression springs 402, push rods 403 and clamping blocks 404 can facilitate the clamping of square or round vehicle lights, thereby saving time for changing clamps and improving work efficiency.

[0033] Rubber blocks 405 are installed on the outer surface of the clamping block 404. Multiple sets of rubber blocks 405 are provided and are evenly distributed on the surface of the clamping block 404. This makes the clamping more stable and avoids the phenomenon of the clamping block 404 directly clamping the vehicle headlight, which would cause wear.

[0034] The clamping base 401 has an internal mounting groove 406 and a sliding groove 407. The mounting groove 406 and the sliding groove 407 are connected internally. Multiple sets of mounting groove 406 and sliding groove 407 are provided, and they correspond one-to-one with compression spring 402 and push rod 403 respectively.

[0035] Compression spring 402 is located in mounting groove 406, and both ends of compression spring 402 are fixedly connected to clamping seat 401 and push rod 403 respectively.

[0036] The push rod 403 is located inside the slide groove 407 and is slidably connected to it, which allows the push rod 403 to have elasticity so that the clamping assembly 4 can clamp the headlights of different shapes.

[0037] The bottom of the clamping base 401 has T-shaped blocks 408. The T-shaped blocks 408 are in pairs and correspond to each other. The inside of the worktable 1 is provided with T-shaped grooves 409 that are adapted to the T-shaped blocks 408. The T-shaped blocks 408 are located inside the T-shaped grooves 409, and the two are slidably connected to facilitate the two sets of clamping components 4 to move closer or further away from each other, thereby ensuring the stability of the two when moving.

[0038] The strength testing component 5 includes a motor 501 located inside the bracket 2. The bottom of the motor 501 has a motor mounting bracket 5011, which is C-shaped and has its other end fixedly connected to one side of the bracket 2, providing support for the motor 501.

[0039] The output end of the motor 501 is fixedly connected to a rotating shaft 502. A fixing block 5021 is provided on the outer surface of the rotating shaft 502. A fixing rod 5022 is fixedly connected to the top of the fixing block 5021. The other end of the fixing rod 5022 is fixedly connected to the bracket 2. The rotating shaft 502 is rotatably connected to the fixing block 5021. The fixing block 5021 and the fixing rod 5022 can provide support for the rotating shaft 502.

[0040] An eccentric wheel 503 is fixedly connected to the other end of the rotating shaft 502. An annular groove 5031 is provided on the inner side of the eccentric wheel 503. A bearing rod 5032 is installed on the inner side of the annular groove 5031. A lifting rod 504 is movably connected to the other end of the bearing rod 5032.

[0041] The outer surface of the lifting rod 504 is slidably connected to a limiting shell 5041. One side of the limiting shell 5041 has a connecting rod 5042, and the other end of the connecting rod 5042 is fixedly connected to the bracket 2, which can limit the lifting rod 504. The limiting shell 5041 ensures that it can continuously move straight up and down, and at the same time, the limiting shell 5041 provides support force through the connecting rod 5042.

[0042] A connecting block 505 is fixedly connected to one end of the lifting rod 504 away from the bearing rod 5032. The bottom of the connecting block 505 has a striking block 506. The strength testing component 5 is located between the two sets of clamping components 4 and on top of the two sets of clamping components 4, which facilitates the hardness testing of the vehicle lights.

[0043] The surface of the workbench 1 has legs 6, and there are multiple sets of legs 6 arranged at equal intervals. A silicone placement plate 601 is installed on the top of the legs 6. The silicone placement plate 601 is located between two sets of clamping components 4 and at the bottom of the strength detection component 5. This facilitates the placement of the vehicle headlights and also prevents the vehicle headlights from rubbing against the surface of the placement plate due to impact during strength detection.

[0044] In use, the vehicle light to be tested is placed on the silicone placement plate 601. Then, the two sets of electric push rods 3 are activated, causing the two sets of clamping seats 401 to move towards the silicone placement plate 601. When the clamping seats 401 contact the vehicle light, the rubber block 405 contacts the vehicle light first. As the clamping seats 401 continue to move, the push rod 403 and the clamping block 404 move towards the inside and surface of the clamping seats 401, respectively. The rubber block 405 transmits the compressive force to the clamping block 404 and the push rod 403, causing the push rod 403 to compress the compression spring 402 and deform it until the vehicle light is completely clamped. By setting multiple sets of compression springs 402, push rods 403 and clamping blocks 404, the system can adaptively adjust according to the shape of the vehicle light, providing a stable lateral clamping force and reducing the shaking and displacement of the object on the silicone placement plate 601.

[0045] Once the headlight is clamped, the motor 501 can be started to drive the rotating shaft 502 to rotate, which in turn drives the eccentric wheel 503 to rotate. As the eccentric wheel 503 rotates, the support rod 5032 adjusts its position according to the annular groove 5031, thereby driving the lifting rod 504 to perform lifting operations. This, in turn, drives the striking block 506 to perform continuous collision operations. By continuously colliding with the headlight, the stress conditions of the headlight in the actual driving environment can be simulated more realistically, making the test results closer to the actual use scenario. This allows for a more accurate assessment of the headlight's quality and reliability, providing a more effective basis for product design improvement and quality control.

[0046] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
