[0025] according to Figure 1The shown embodiment is a kind of automobile wiring harness tensile test bench, including a support bracket 1, on which a wiring harness protection guide mechanism 2, a winding wiring harness fixing mechanism 3, a wiring harness stretching and displacement mechanism 4, and a tension testing mechanism 5 are provided. The wiring harness protection guide mechanism 2 is arranged at the center position of the support bracket 1, and the winding wiring harness fixing mechanism 3 is provided with two groups, which are respectively arranged on both sides of the wiring harness protection guide mechanism 2. The winding wiring harness fixing mechanism 3 is slidingly connected to the support bracket 1, and the wiring harness stretching and displacement mechanism 4 is fixed to one side of the winding wiring harness fixing mechanism 3 and is fixed to the support bracket 1.

The winding wiring harness fixing mechanism 3 facilitates winding and fixing the wiring harness, the wiring harness stretching and displacement mechanism 4 facilitates pulling test on the wiring harness, and the tension testing mechanism 5 facilitates reading the pulling force.

[0026] The utility model is based on Figure 1 、 Figure 2 The support bracket 1 includes a support base plate 6, a support vertical rod 7, and a support horizontal plate 8. The support vertical rod 7 is provided in two groups and is symmetrically arranged on both sides of the upper end of the support base plate 6. The support horizontal plate 8 is fixed between the two support vertical rods 7.

[0027] The utility model is based on Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The supporting transverse plate 8 is provided with a placement slot 9, and the wire harness protection guide mechanism 2 is provided in the placement slot 9. The wire harness protection guide mechanism 2 includes a rotating shaft 10 and a guide wheel 11. The rotating shaft 10 is provided in the placement slot 9 and is rotatably connected to the supporting transverse plate 8. The guide wheel 11 is rotatably sleeved on the rotating shaft 10. The outer surface of the guide wheel 11 is an inner concave surface. The guide wheel 11 avoids friction between the wire harness and the supporting transverse plate 8, which causes the wire harness to be damaged. The outer surface of the guide wheel 11 is an inner concave surface, which reduces the possibility of separation of the wire harness and the guide wheel 11.

[0028] The utility model is based on Figure 1 、 Figure 4 、 Figure 5 The winding type wire harness fixing mechanism 3 includes a supporting slide 12, a supporting strip 13, and a winding mechanism 14. The supporting slide 12 is slidably mounted on the supporting cross plate 8, the supporting strip 13 is fixedly connected to the supporting slide 12, and the winding mechanism 14 is fixedly connected to the supporting strip 13. The winding mechanism 14 facilitates winding and fixing the wire harness.

[0029] The utility model is based on Figure 5 、 Figure 6The winding mechanism 14 includes a winding shaft 15, a threaded sleeve 16, a winding pressure rod 17, and a hook 18. The winding shaft 15 is fixedly connected to the supporting strip 13, the threaded sleeve 16 is threadedly connected to the winding shaft 15, the winding pressure rod 17 is rotatably arranged on the threaded sleeve 16, and the hook 18 is fixed to the winding pressure rod 17. When the threaded sleeve 16 rotates, it drives the winding pressure rod 17 to rotate and move laterally, and the wire harness is wound on the winding shaft 15. Since the winding pressure rod 17 will move horizontally, the wire harness is prevented from being wound on the same place of the winding shaft 15.

[0030] The utility model is based on Figure 1 、 Figure 2 、 Figure 5 、 Figure 7 The wire harness stretching and displacement mechanism 4 includes an electric telescopic rod 19 and a connecting plate 20.

[0031] The utility model is based on Figure 1 、 Figure 2 、 Figure 4 、 Figure 8 The tensile testing mechanism 5 includes a fixing seat 21 and a dynamometer 22. The fixing seat 21 is fixedly connected to the supporting base plate 6 and is located at the lower end of the placement slot 9. The dynamometer 22 is arranged in the fixing seat 21, and its upper end passes through the fixing seat 21. The dynamometer 22 is placed in the fixing seat 21 to facilitate its placement and removal.

[0032] The principle of the present utility model is as follows: when in use, after the wire harness is bent, the middle part is arranged to pass through the dynamometer 22, and the two ends of the wire harness pass through the winding shaft 15 and the winding pressure rod 17, and then pass through the draw hook 18, and the threaded sleeve 16 is rotated. Since the threaded sleeve 16 is threadedly connected to the winding shaft 15, the threaded sleeve 16 will translate when it rotates, and the rotating and translating winding pressure rod 17 will press the wire harness around the surface of the winding shaft 15, thereby fixing the two ends of the wire harness. After fixation, the electric telescopic rod 19 starts to drive the supporting slide 12 to slide, and drives the winding mechanism 14 to move, and performs a pulling test on the wire harness. The pulling force can be read through the dynamometer 22.

[0033] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
