Description

Technical Field

[0001] The utility model relates to the technical field of automotive wiring harness testing, in particular to a stretching test bench for automotive wiring harnesses. Background Technique

[0002] With the widespread application of automotive electronic control technology, there are more and more electrical components, and accordingly more and more wires. The automotive wiring harness has become more and more complex and the failure rate has increased accordingly. Before leaving the factory and being put into use, various measurements generally need to be carried out on the automotive wiring harness to reduce the failure rate in turn. Among them, a relatively important test is to carry out a stretching test on it. Since it needs to be reasonably arranged inside the vehicle, there are relatively high requirements for the stretching ability of the automotive wiring harness.

[0003] In the prior art, in some small production enterprises, in order to reduce production costs, for the detection part of the automotive wiring harness, the automotive wiring harness is manually pulled to detect the strength of the automotive wiring harness. However, this method is prone to fatigue after long-term work. In addition, when some corresponding equipment is used for detection, usually only single wires can be detected, resulting in a decrease in detection efficiency. In addition, during the stretching process, when the pulling force is too large, it is easy to break, and without any protective measures, it is easy to splash and hurt the staff, making the safety of the staff unable to be guaranteed.

Specific embodiments

[0025] 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 creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 - 5 , the present utility model provides an automotive wire harness stretching test bench, including a support leg 1. The top end of the support leg 1 is fixedly connected to a table body 2. The inner wall of the table body 2 is fixedly connected to an electric slide rail 3. The electric slide rail 3 is a prior art and can start working by connecting to a power supply. The mobile end of the electric slide rail 3 is fixedly connected to a slider 4. By the operation of the electric slide rail 3, the slider 4 can move back and forth, so as to detect the strength of the data cable. A value can be set. When the data cable does not break when moving to a certain position, it is a qualified data cable. The top end of the outer wall of the slider 4 is fixedly connected to a fixed frame 5. The top end of the outer wall of the fixed frame 5 is fixedly connected to a clamping block 12. The inner wall of the table body 2 is slidably connected to a baffle 14. The baffle 14 is U-shaped and can block the stretched automotive wire harness to prevent unnecessary damage caused by breakage. The inner wall of the baffle 14 is slidably connected to a sliding plate 15. The setting of the sliding plate 15 prevents the slider 4 from moving too far, resulting in the baffle 14 being unable to completely block the automotive wire harness well. The bottom end of the outer wall of the sliding plate 15 contacts the surface of the table body 2. After the sliding plate 15 is clamped with the clamping block 12 at the top of the fixed frame 5, the movement of the fixed frame 5 will drive the sliding plate 15 to move accordingly to block the automotive wire harness. The top end of the outer wall of the sliding plate 15 is fixedly connected to a convex block 16. The outer wall of the convex block 16 is rotatably connected to a clamping rod 17. The clamping rod 17 is clamped with the clamping block 12. The clamping between the two enables the position of the sliding plate 15 to be driven to move when the left fixed frame 5 moves, so as to completely block the automotive wire harness.

[0027] Furthermore, a guiding coil 6 is fixedly connected to the inner wall of the fixing frame 5. Multiple groups of guiding coils 6 are provided, which can simultaneously perform tensile tests on multiple groups of automotive wire harnesses. An arc-shaped groove is provided on the inner wall of the guiding coil 6. The pressing block 13 is arc-shaped and is adapted to the arc-shaped groove. When not in use, it can be hidden in the arc-shaped groove inside the guiding coil 6, and will not affect the passing of the automotive wire harness through the guiding coil 6. A threaded rod 7 is threadedly connected to the inner wall of the top end of the fixing frame 5. The surface of the threaded rod 7 penetrates through a pressing plate 8. The pressing plate 8 will not rotate along with the rotation of the threaded rod 7. A handle 10 is fixedly connected to the top end of the outer wall of the threaded rod 7. By rotating the handle 10, the up and down movement of the threaded rod 7 is adjusted. A pressing ring 9 is fixedly connected to the outer wall of the threaded rod 7. By moving the pressing ring 9, the pressing plate 8 is squeezed downwards to press the automotive wire harness. An elastic telescopic rod 11 is fixedly connected to the bottom end of the outer wall of the pressing plate 8. A spring is provided inside the elastic telescopic rod 11, which is prior art. The elastic telescopic rod 11 penetrates and is slidably connected to the inner wall of the fixing frame 5, and the elastic telescopic rod 11 penetrates and is slidably connected to the inner wall of the guiding coil 6. The function of the elastic telescopic rod 11 penetrating the fixing frame 5 and the guiding coil 6 is that it will not affect the elastic effect of the elastic telescopic rod 11. The end of the elastic telescopic rod 11 away from the pressing plate 8 is fixedly connected to the pressing block 13. The pressing block 13 is slidably connected to the inner wall of the guiding coil 6. By moving the pressing block 13 downwards, the automotive wire harness inside the guiding coil 6 is fixed.

[0028] In the present utility model, during use, one end of the automotive wire harness that needs to be subjected to a tensile test is placed inside the guiding coil 6 within the fixing frame 5 on the right side of the table body 2. By rotating the handle 10, the threaded rod 7 rotates. When the threaded rod 7 rotates, the pressing ring 9 fixedly connected to its outer wall also rotates accordingly. When rotating, its bottom end will squeeze the pressing plate 8 slidably connected to the surface of the threaded rod 7 to move downwards. At this time, the elastic telescopic rod 11 at the bottom end of the pressing plate 8 will move the pressing block 13 of the guiding coil 6 downwards, and squeeze and fix the automotive wire harness inside the guiding coil 6. When the automotive wire harness is completely squeezed and clamped, at this time, the threaded rod 7 will stay at the current position without moving due to its self-locking property. At this time, the sliding baffle 14 inside the table body 2 is pulled out. At this time, the sliding plate 15 inside the baffle 14 is pulled out. At this time, the other end of the automotive wire harness is placed at the guiding coil 6 within another group of fixing frames 5, and it is fixed through the above operations. At this time, the clamping rod 17 that rotates at the top end of the sliding plate 15 is stuck with the block 12 at the top end of the left fixing frame 5. At this time, the stretching of the automotive wire harness can be tested by starting the electric slide rail 3 to drive the movement of the slider 4. When the electric slide rail 3 drives the fixing frame 5 that needs to move to move, the sliding plate 15 will also move along with the movement of the fixing frame 5 to block the automotive wire harness. When the electric slide rail 3 drives the slider 4 to move to perform a tensile test on the automotive wire harness, some unqualified wire harnesses will break during the stretching process.

[0029] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
