Technical Field
[0001] The utility model relates to the technical field of anti-stress detection, in particular to an anti-stress detection device for a car door hinge. Background Technique
[0002] The stress test of a car hinge is an important link to ensure the stability and safety of the car door. As a key component connecting the car door and the vehicle body, the car hinge not only needs to bear the weight of the door body, but also maintain stability and safety during the opening and closing processes. Therefore, strict stress tests on the car hinge are necessary steps to evaluate its performance and durability. The hinge stress test mainly includes vertical load tests, static load tests, and dynamic load tests. These tests can comprehensively evaluate the performance of the hinge under different conditions and ensure that it can stably support the car door under various circumstances.
[0003] The vertical load test mainly simulates the weight of the car door itself and the influence of the external environment, such as wind pressure and vibration. By testing the bearing capacity of the hinge, it is ensured that the car door can be normally closed and potential safety hazards are avoided. The static load test is divided into two states: the open state and the closed state, and the stability and bearing capacity of the hinge in these two states are respectively tested to ensure that it will not loosen or break during normal use. Currently, different detection devices are usually required to detect the static anti-stress and dynamic anti-stress of the hinge, which not only increases the test cost but also affects the efficiency of hinge detection. Therefore, an anti-stress detection device for a car door hinge is proposed to solve the above problems. Content of the Utility Model

Specific implementation manner
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1 to 4 , a door hinge stress resistance detection device in this embodiment includes a detection table 1, a frame 2 is fixedly installed on the top of the detection table 1, a telescopic rod 4 is fixedly installed on the inner top wall of the frame 2, a cross bar 3 is fixedly connected to the telescopic end of the telescopic rod 4, a clamping assembly is arranged at the bottom of the cross bar 3, and a driving member is arranged on the frame 2.
[0025] The clamping assembly includes a fixed rod 6, the fixed rod 6 is fixedly connected to the bottom of the cross bar 3, a U-shaped plate 18 is fixedly connected to the bottom of the fixed rod 6, a bidirectional threaded rod 19 is rotatably connected inside the U-shaped plate 18, clamping plates 20 are threadedly connected to both sides of the outside of the bidirectional threaded rod 19, the bottom of the bidirectional threaded rod 19 penetrates through the U-shaped plate 18 and extends to the outside and is fixedly connected to a star-shaped handle 21, a guiding slider is fixed on one side of the clamping plate 20, and a guiding chute is opened on the inner side wall of the U-shaped plate 18, and the guiding slider is slidably connected inside the guiding chute.
[0026] It should be noted that the guiding slider is slidably connected inside the guiding chute to restrict the clamping plate 20. When the bidirectional threaded rod 19 rotates clockwise or counterclockwise, it will drive the two clamping plates 20 to move relative to each other or in opposite directions, thus facilitating the fixation of the hinge 17 to be measured.
[0027] The driving member includes a driving motor 5 which is fixedly installed on the side wall of the frame 2. A rotating rod 7 is fixedly connected to the output shaft of the driving motor 5. The rotating rod 7 is rotatably connected to the frame 2. Cam 8s are fixedly connected to both the left and right sides outside the rotating rod 7, and the cam 8s abut against the bottom of the cross bar 3.
[0028] In this embodiment, a counterweight assembly is provided on the top of the test bench 1. The counterweight assembly includes a limiting sliding rod 9. A placing plate 10 is slidably connected to the outside of the limiting sliding rod 9. A plurality of hanging rings 101 are fixedly connected to the top of the placing plate 10. A rope 11 is installed on the hanging ring 101. One end of the rope 11 away from the hanging ring 101 is installed with a chain 15. One end of the chain 15 away from the rope 11 is fixedly connected to a locking hook 16. A hinge 17 is clamped between the two clamping plates 20. The locking hook 16 is hung on the assembly hole of the hinge 17. The number of the hanging rings 101 is three, and all three ropes 11 are fixedly connected to the chain 15.
[0029] It can be understood that during the static stress resistance test, the hinge 17 is fixed by the clamping assembly, and then the locking hook 16 is hung on the hinge 17. By adding counterweight plates on the placing plate 10, the static load of the hinge 17 is detected in sequence. When the driving motor 5 drives the rotating rod 7 to rotate, the two cam 8s can be synchronously rotated, so as to push the cross bar 3 to move up and down, and then the load-bearing capacity of the hinge 17 during bumpy conditions can be simulated, thus facilitating the detection of the static stress resistance and dynamic stress resistance of the hinge. This device is integrated, thereby improving the detection efficiency.
[0030] Among them, a counterweight plate is placed on the top of the placing plate 10. The counterweight plate is sleeved on the outside of the limiting sliding rod 9. One end of the limiting sliding rod 9 away from the test bench 1 is threadedly connected with a cap 12.
[0031] By placing counterweight plates with different weights on the top of the placing plate 10, it is convenient to detect the load-bearing capacity of the hinge 17.

[0033] When the sliding blocks 22 are slidably connected inside the chutes 23, when the cam 8 rotates, it will push the cross bar 3 to move up and down, so as to simulate the dynamic stress resistance of the hinge 17 under bumpy conditions.
[0034] Further, a vertical plate 13 is fixedly installed on the right side of the top of the inspection table 1, and a monitoring camera 14 is installed on one side of the vertical plate 13 close to the hinge 17.
[0035] It should be noted that a control panel is installed on the surface of the inspection table 1, and both the drive motor 5 and the monitoring camera 14 are electrically connected to the control panel.
[0036] The working principle of the above embodiment is as follows: during use, place the hinge 17 to be inspected between the two clamping plates 20, rotate the star-shaped handle 21 to drive the bidirectional threaded rod 19 to rotate, so that the two clamping plates 20 move relatively to clamp and fix the male hinge of the hinge 17. Then, hang the locking hook 16 on the female hinge, add counterweight plates of different weights to the placement plate 10, and the static load capacity of the hinge 17 can be detected. Then, drive the rotating rod 7 to rotate through the drive motor 5, so that the two cams 8 rotate synchronously, thereby pushing the cross bar 3 to move up and down, and the load capacity of the hinge 17 during bumpy conditions can be simulated, so as to facilitate the detection of the static stress resistance and dynamic stress resistance of the hinge. The device is integrated, thereby improving the detection efficiency.
