[0018] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0019] Example

[0020] like Figures 1-3 As shown in the figure, an embodiment of this utility model discloses an automotive wiring harness tensile testing device, the structure of which mainly includes a platform 1. On the top of the platform 1, directional wheels 2 are designed. These directional wheels 2 guide the movement of the wiring harness during the testing process, ensuring the accuracy of the test. In addition, a clamping member 3 is fixed on the platform 1 to fix one end of the wiring harness, while a clamping member 4 can move laterally to pull the other end of the wiring harness for testing. A driving member 5 is also installed on the platform 1 to drive the movement of the clamping member 4. The clamping member 3 and the clamping member 4 are respectively mounted on the platform 1 via mounting blocks 7 and 6. This design makes the installation and removal of the clamping members more convenient, facilitating maintenance and replacement. Through the above design, precise tensile testing of the wiring harness is achieved, improving the efficiency and accuracy of the test.

[0021] In this invention, clamping component 3 and clamping component 4 have the same structure, both including a mounting base 31. The mounting base 31 is detachably connected to the mounting block, facilitating the replacement of clamping components of different specifications. A support spring 32 is installed on the inner wall of the mounting base 31, with the top of the spring connected to a clamping plate 33. This design allows the clamping plate 33 to adapt to wire harnesses of different diameters, ensuring clamping stability. Furthermore, an adjustment component is installed on the top of the mounting base 31, allowing adjustment of the height of the clamping plate 33 to accommodate wire harnesses of different thicknesses. The design of the clamping components makes the device suitable for various specifications of wire harnesses, improving the versatility and flexibility of testing.

[0022] In this invention, the adjusting component includes a threaded ring 34 mounted on the top of the mounting base 31, with its inner wall threadedly connected to a threaded post 35. When the threaded ring 34 is rotated, the threaded post 35 moves up and down, thereby pushing or pulling the clamping plate 33 to adjust its height. To prevent the clamping plate 33 from shifting during movement, a limiting rod 36 is also installed on the inner wall of the mounting base 31, with the clamping plate 33 and the limiting rod 36 connected through it, ensuring stable movement of the clamping plate 33. Through the design of the adjusting component, precise adjustment of the clamping plate height is achieved, improving the stability and accuracy of clamping.

[0023] In this invention, the drive component 5 includes a mounting plate 51 installed on the top of the platform 1, with a servo motor 52 mounted on the side of the mounting plate 51. The output end of the servo motor 52 is connected to a threaded rod 53, the surface of which is threadedly connected to a threaded seat 54. When the servo motor 52 starts, it drives the threaded rod 53 to rotate, thereby driving the threaded seat 54 to move. To ensure stable movement of the threaded seat 54, a guide rod 55 is also installed on the mounting plate 51, which is connected through the mounting block 6, serving as a guide and support. The design of the drive component enables precise driving of the clamping component 4, improving the automation and accuracy of the test.

[0024] In this invention, to further improve the stability of the clamping component, a limiting seat 8 is also installed on the side of the mounting base 31. The limiting seat 8 is respectively fitted onto the surfaces of mounting block 6 and mounting block 7, and can be fixed to the mounting blocks by the cooperation of nuts 81 and bolts 82. This design not only increases the stability of the clamping component but also facilitates fine-tuning. The limiting seat design improves the stability and fine-tuning capability of the clamping component, ensuring the accuracy and reliability of the test.

[0025] In this invention, a pad 71 is also installed on the surface of mounting block 7 or mounting block 6. The top of the pad 71 contacts the limiting seat 8, providing support and cushioning. This design not only improves the stability of the limiting seat but also reduces wear on the mounting blocks, extending the service life of the device. The pad design enhances the durability and stability of the device, ensuring long-term accuracy and reliability of the test.
