This device has some problems. Although it can be used effectively to test automotive headlights, it can only test the pressure on the headlight bracket. Because it is not suitable for simulating vibrations under road operating conditions, the testing effect of this fixture is difficult to achieve the expected results.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a dynamic automotive parts bracket testing fixture, including a body 1, a frame 2 fixedly connected to the top of the body 1, and the frame 2 connected to a moving block 3 via a moving mechanism. The moving mechanism includes the frame 2, the moving block 3, a first motor 4, a first rotating shaft 5, a gear 6, and a rack 7. The frame 2 and the moving block 3 are slidably connected, and the interior of the moving block 3 is fixedly connected to the first motor 4. The first motor 4 is connected to the first rotating shaft 5, the first rotating shaft 5 is connected to the gear 6, the gear 6 meshes with the rack 7, and the rack 7 is fixedly connected to the interior of the frame 2. The lower part of the moving block 3 is fixedly connected to a fixed block 8, the upper part of the fixed block 8 is fixedly connected to a second motor 9, and the second motor 9 is connected to a rotating rod 10. A connecting rope 11 is provided on the surface of the rotating rod 10. The front end of the connecting rope 11 is connected to a buckle 12. The interior of the buckle 12 is fixedly connected to a first spring 13, and the front end of the first spring 13 is fixedly connected to a locking block 14. The tail end of the locking block 14 is hinged to the buckle 12.

[0022] When in use, press the latch 14 above the latch 12 so that the latch 14 is adjusted by the hinge shaft and the first spring 13 inside retracts. At this time, after the latch 12 is connected to the bracket, the first motor 4 drives the first rotating shaft 5 to rotate, so that the first rotating shaft 5 drives the gear 6 to rotate. Since the gear 6 and the rack 7 mesh, the moving block 3 slides above the frame 2, so that the moving block 3 moves the bracket below to the test platform 22. Then, the second motor 9 drives the rotating rod 10 to rotate, so that the connecting rope 11 on the surface of the rotating rod 10 is released, so that the bracket is placed above the test platform 22.

[0023] The machine body 1 is connected to the test platform 22 via a vibration mechanism. The vibration mechanism includes a third motor 15, a second rotating shaft 16, a cam 17, a roller 19, a moving rod 20, a second spring 21, and the test platform 22. The machine body 1 is fixedly connected to the third motor 15, and the third motor 15 is connected to the second rotating shaft 16. The second rotating shaft 16 is connected to the cam 17, the cam 17 contacts the roller 19, and the roller 19 is fixedly connected to the moving rod 20. The moving rod 20 is slidably connected to the inside of the machine body 1. The surface of the moving rod 20 is provided with the second spring 21, and the upper end of the moving rod 20 is fixedly connected to the bottom of the test platform 22. The second rotating shaft 16 is connected to the transmission belt 18, and the second rotating shaft 16 is symmetrical about the center of the transmission belt 18. The test platform 22 and slide rod 23 are slidably connected, and slide rod 23 is fixedly connected to the top of the machine body 1. The top of the test platform 22 is fixedly connected to the first push rod 24, and the front end of the first push rod 24 is fixedly connected to the clamping plate 25. The machine body 1 is equipped with a hydraulic rod 26, and the front end of the hydraulic rod 26 is fixedly connected to the pressure plate 27. The pressure plate 27 is slidably connected to the support rod 28, and the support rod 28 is fixedly connected to the inside of the machine body 1. The machine body 1 is equipped with a pressure sensor 29, and the machine body 1 is equipped with a discharge mechanism. The discharge mechanism includes a second push rod 30 and a push plate 31. The machine body 1 is fixedly connected to the second push rod 30, and the upper end of the second push rod 30 is fixedly connected to the push plate 31.

[0024] The first push rods 24 on both sides are activated to move the clamping plates 25, causing them to contact the bracket and fix it in place. At this time, the third motor 15 is activated to rotate the second rotating shaft 16, causing the transmission belt 18 on the surface of the second rotating shaft 16 to rotate synchronously. The second rotating shafts 16 on both sides rotate synchronously, causing the cam 17 to rotate. When the protrusion of the cam 17 contacts the roller 19, it pushes the roller 19 forward. Simultaneously, the roller 19 drives the moving rod 20 to slide inside the machine body 1, causing the surface of the moving rod 20 to... The second spring 21 retracts, at which point the moving rod 20 pushes the upper test platform 22, causing the test platform 22 to slide above the slide rod 23. Since the cam 17 rotates continuously, when the protrusion separates from the roller 19, the retracted second spring 21 resets, simultaneously driving the moving rod 20 to reset, until the protrusion rotates one revolution and pushes again, causing the test platform 22 to vibrate continuously up and down, simulating vibrations under road operating conditions. During use, the speed of the third motor 15 can be adjusted to regulate the rotation speed of the cam 17 and adjust the vibration frequency. To adapt to the needs of various vehicle models, the vibration resistance of the bracket is tested. After the vibration resistance test is completed, the bracket is loosened. At this time, the second motor 9 drives the rotating rod 10 to reverse, causing the connecting rope 11 to retract and the bracket to rise. Then, the bracket is moved again by the moving mechanism to the push plate 31 inside the body 1. The second motor 9 releases the connecting rope 11, allowing the bracket to be placed above the push plate 31. At this time, the hydraulic rod 26 is activated, causing the pressure plate 27 to slide above the support rod 28, so that the pressure plate 27 contacts the bracket. Since the buckle 12 is smaller than the bracket and When positioned at the top, the pressure plate 27 will not contact the buckle 12, which would cause errors in the test results. At this time, the pressure plate 27 contacts the bracket, causing the bracket to move until the pressure sensor 29 on one side of the bracket contacts it. At this time, the hydraulic rod 26 continues to apply pressure and transmit it to the bracket. With the help of the pressure sensor 29 on one side, the specific pressure can be known until the bracket is deformed or damaged, and the maximum pressure that the bracket can withstand can be known. After the test is completed, the pressure plate 27 resets, and the second push rod 30 drives the push plate 31 to move, pushing out the remaining bracket fragments after the test for easy collection.

[0025] Working principle: When using the dynamic automotive parts bracket testing fixture, pressing the latch 14 above the latch 12 causes the latch 14 to adjust via the hinge shaft, while the internal first spring 13 retracts. This connects the latch 12 and the bracket. The first motor 4 drives the first rotating shaft 5 to rotate, which in turn drives the gear 6 to rotate. Since the gear 6 meshes with the rack 7, the moving block 3 slides above the frame 2, moving the bracket below to the test platform 22. Then, the second motor 9 drives the rotating rod 10 to rotate, releasing the connecting rope 11 on the surface of the rotating rod 10. Once the bracket is placed on the test platform 22, the first push rods 24 on both sides are activated, moving the clamping plate 25. The movement causes the clamps 25 on both sides to contact the bracket, fixing the bracket. At this time, the third motor 15 is started to drive the second rotating shaft 16 to rotate, causing the transmission belt 18 on the surface of the second rotating shaft 16 to rotate synchronously. The second rotating shafts 16 on both sides rotate synchronously, causing the second rotating shaft 16 to drive the cam 17 to rotate. When the protrusion of the cam 17 contacts the roller 19, it pushes the roller 19. At the same time, the roller 19 drives the moving rod 20 to slide inside the machine body 1, causing the second spring 21 on the surface of the moving rod 20 to contract. At this time, the moving rod 20 pushes the test platform 22 above, causing the test platform 22 to slide above the slide rod 23. Since the cam 17 is constantly rotating, when the protrusion separates from the roller 19, the contracted second spring 21... The second spring 21 resets, simultaneously driving the moving rod 20 to reset until the protrusion rotates one revolution and then pushes again, causing the test bench 22 to vibrate continuously up and down, simulating vibrations under road operating conditions. During use, the speed of the third motor 15 can be adjusted to regulate the rotation speed of the cam 17, thereby adjusting the vibration frequency to suit various vehicle models and testing the vibration resistance of the bracket. After the vibration resistance test is completed, the bracket is released. At this time, the second motor 9 drives the rotating rod 10 to reverse, causing the connecting rope 11 to retract and lift the bracket. Then, the moving mechanism moves the bracket above the push plate 31 inside the machine body 1. Finally, the second motor 9 releases the connecting rope 11, placing the bracket above the push plate 31. At this point, the hydraulic rod 26 is activated, causing the pressure plate 27 to slide above the support rod 28, making the pressure plate 27 contact the bracket. Because the latch 12 is smaller than the bracket and positioned above it, the pressure plate 27 will not contact the latch 12, leading to errors in the test results. Now, the pressure plate 27 contacts the bracket, causing it to move until the pressure sensor 29 on one side of the bracket contacts it. The hydraulic rod 26 continues to apply pressure, transmitting it to the bracket. The pressure sensor 29 on one side can then determine the specific pressure until the bracket deforms or is damaged, revealing the maximum pressure the bracket can withstand. After the test, the pressure plate 27 resets, and the second push rod 30 moves the push plate 31, pushing out any remaining bracket fragments for easy collection, thus completing the series of tasks.The contents not described in detail in this specification are existing technology known to those skilled in the art.
