Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to an automotive wiring harness fatigue resistance measuring device. Background Technology

[0002] Automobiles have numerous parts, and to ensure their operational stability, they undergo testing. Internal wiring connects different components, and to ensure seamless integration, measuring devices are used to perform fatigue tests on the wires. However, these measuring devices have some shortcomings and areas for improvement: 1. CN211013875U only allows testing of one wire at a time, resulting in low efficiency and reduced testing effectiveness; 2. When using weights to test the lower end of the wire, if the wire breaks, the falling weights can dent the lower support frame, damaging the measuring device. Therefore, we propose a fatigue testing device for automotive wiring harnesses. Utility Model Content

[0022] Please see Figure 1-4 This utility model provides a technical solution: A fatigue resistance measuring device for automotive wiring harnesses includes a support frame 1. An operation display panel 2 is fixedly connected to the left front end of the support frame 1. A connecting wire 3 is fixedly connected to the left end of the support frame 1. A protective mechanism 4 is fixedly connected to the lower wall of the support frame 1. A first circular hole 5 is opened at the upper left end of the support frame 1. A second circular hole 6 is opened at the upper right end of the support frame 1. A fixing mechanism 7 is fixedly connected to the inner wall of the first circular hole 5. A rectangular frame 8 is fixedly connected to the lower left and lower right sides of the support frame 1. Several sets of through rods 9 are inserted and fixedly connected inside the rectangular frame 8. Each set of through rods 9 is movably engaged with a limit shaft 10.

[0023] In this embodiment, the fixing mechanism 7 includes a forward and reverse motor 11. A round shaft 12 is fixedly connected to the output end of the forward and reverse motor 11. A rotating frame 13 is fixedly connected to the right end of the round shaft 12. Several sets of extension cylinders 14 are fixedly connected to the front and rear ends of the rotating frame 13. A telescopic threaded rod 15 is threaded and snapped into the inside of each set of extension cylinders 14. A clamping plate 16 is fixedly connected to one end of each set of telescopic threaded rods 15 located inside the rotating frame 13. A round shaft 12 is fixedly connected to the middle of the right end of the rotating frame 13. Two sets of limiting plates 17 are fixedly connected to the round shaft 12 on the right side. Several sets of convenient shafts 18 are equidistantly arranged on the surface of the round shaft 12 on the right side. The forward and reverse motor 11 is fixedly connected to the inner wall of the first round hole 5. The round shaft 12 and the convenient shaft 18 on the right side are inserted into the second round hole 6. The two sets of limiting plates 17 are located at the left and right ends of the right structure of the support frame 1, respectively. The convenient shaft 18 is in contact with the inner wall of the second round hole 6 but is not fixed.

[0024] Through the above scheme, the several sets of telescopic threaded rods 15 and clamping plates 16 on the rotating frame 13 can clamp and fix the wires together, and detect several sets of wires at the same time, improving the detection efficiency. In addition, the convenient shaft 18 movably set on the right round shaft 12 can reduce friction during rotation and facilitate detection.

[0025] In this embodiment, the protective mechanism 4 includes a placement box 19 and a lifting plate 20. The front left, front right, rear left and rear right of the placement box 19 are all provided with limit grooves 21. The lower front and lower rear of the lifting plate 20 are fixedly connected with several sets of support springs 22. The front left, front right, rear left and rear right of the lifting plate 20 are all fixedly connected with limit blocks 23. The upper end of the lifting plate 20 is fixedly connected with a protective pad 24. The placement box 19 is fixedly connected to the lower wall of the support frame 1. The support springs 22 are fixedly connected to the lower wall of the placement box 19. The limit blocks 23 are respectively inserted and engaged with the nearby limit grooves 21.

[0026] With the above solution: the lower lifting plate 20 can easily hold the weight, reducing contact with the support frame 1; the protective pad 24 fixedly connected to the surface of the lifting plate 20 and the lower support spring 22 can reduce the impact of the weight falling down and prevent damage to the support frame 1.

[0027] It should be noted that this utility model is a fatigue testing device for automotive wiring harnesses. During use, the telescopic threaded rod 15 is first rotated, causing the two sets of adjacent clamping plates 16 to move away and then close again to clamp and fix the wire. The lower part of the wire passes between the two sets of limiting shafts 10. Then, a weight is attached to the lower part of the wire. The rotating frame 13, with its several sets of telescopic threaded rods 15 and clamping plates 16 arranged via several sets of extension cylinders 14, can jointly clamp several sets of wires, simultaneously testing multiple sets of wires and improving testing efficiency. Weights of different weights are attached to the lower ends of the several sets of wires. The weights are positioned at... The upper part of the placement box 19 is driven by the operation display panel 2 to drive the forward and reverse motor 11, which drives the rotating frame 13 on the right to rotate forward and reverse. The convenient shaft 18 is movably set on the round shaft 12 at the right end of the rotating frame 13, which can reduce friction during rotation. After the detection is completed, if the wire breaks, the weight at the bottom falls on the lifting plate 20, which can prevent it from contacting the support frame 1. At the same time, the protective pad 24 fixedly connected to the upper part of the lifting plate 20 and the support spring 22 fixedly connected to the lower end of the lifting plate 20 together reduce the impact of the weight falling, reduce the impact force, and prevent damage to the support frame 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
