[0002] In order to detect the bending performance of the wire harness, a wire swing tester can be used for testing. The wire swing tester fixes the sample on a fixture and adds a certain load. It swings left and right during the test. After a certain number of times, the wire breakage rate is detected and the total number of swings is checked. The machine can automatically count and stop operating when the sample is bent to the point of breaking and power cannot be supplied.

[0003] During the test, the wire harness sample needs to be stably fixed on the turntable of the wire swing testing machine. A wire harness clamp is needed to fix it. Currently, the wire harness is clamped and fixed by bolt extrusion. However, in the process of assembling and disassembling the sample, frequent tightening of the bolts takes up much time and energy. Therefore, it is necessary to provide a fully automatic wire harness bending performance test fixture, which adopts a quick locking method to clamp and fix the wire harness in a short time. At the same time, it is also simple and quick to disassemble, thereby improving the test efficiency of the wire harness bending performance. Utility Model Content

Through the coordinated use of the circular hole 10, the threaded tube 11 and the fixed clamp seat 13, the shell 2 can be displaced at the front side of the test turntable 1, so that the shell 2 can be adjusted relative to the center position of the test turntable 1, thereby adjusting the bending amplitude of the wire harness, a slidable extrusion clamp 3 is arranged on the front side of the inner cavity of the shell 2, and a fixing sleeve 7 is fixedly connected to the front side of the extrusion clamp 3, and a spring 8 is arranged in the inner cavity of the fixing sleeve 7, and the rear end of the spring 8 contacts the front side of the extrusion clamp 3, and an extrusion pin 4 is arranged through the front side of the shell 2, and the front side of the extrusion clamp 3 is arranged There is an anti-slip assembly 5, which includes a fixed tube 51 fixedly connected to the front side of the shell 2, the inner cavity of the fixed tube 51 is fixedly connected to a fixed ring 52, the extrusion pin 4 is located in the inner cavity of the fixed tube 51 and the fixed ring 52, the rear end of the extrusion pin 4 penetrates into the inner cavity of the fixed sleeve 7 and is welded with a slide 9, the slide 9 is slidably connected to the inner cavity of the fixed sleeve 7, the rear side of the slide 9 is welded to the front end of the spring 8, and the fixed sleeve 7, the spring 8 and the slide 9 are used in coordination to elastically squeeze the extrusion splint 3 The extrusion clamp 3 and the fixed clamp 6 can adapt to wire harnesses of different diameters, and play a role of elastic clamping on the wire harness. Two anti-slip blocks 53 are fixedly connected to the surface of the extrusion pin 4. The top and bottom of the front side of the fixing ring 52 are provided with openings 54 adapted to the anti-slip blocks 53. Both ends of the rear side of the fixing ring 52 are provided with limiting grooves 55 adapted to the anti-slip blocks 53. The rear side of the inner cavity of the shell 2 is fixedly connected with a fixed clamp 6, and the wire harness is clamped between the extrusion clamp 3 and the fixed clamp 6.

[0023] Working principle: When the utility model is used, the user inserts the wire harness into the inner cavity of the housing 2 so that the wire harness is located between the extrusion clamping plate 3 and the fixed clamping plate 6. Then the user pushes the extrusion pin 4 to the rear side so that the anti-dropping block 53 passes through the opening 54. At the same time, the slide 9 squeezes the spring 8. After being squeezed, the spring 8 pushes the extrusion clamping plate 3 so that the extrusion clamping plate 3 is stably pressed on the surface of the wire harness to limit the wire harness. Then the user rotates the extrusion pin 4 90 degrees and releases the extrusion pin 4. Under the elastic action of the spring 8, the extrusion pin 4 moves back to the front side. The threaded tube 11 is elastically moved a certain distance so that the anti-slip block 53 is engaged in the inner cavity of the limiting groove 55, so that the extrusion pin 4 is stably in the inner cavity of the fixing tube 51, thereby making the wiring harness stably clamped. Then the user can adjust the swing amplitude during the large bending process according to the test strength. When adjusting, the user rotates the threaded tube 11. During the rotation process, due to the threaded meshing action between the threaded tube 11 and the threaded rod 12, the threaded tube 11 drives the housing 2 to move on the front side of the test turntable 1, and adjusts the distance between the center of the housing 2 and the test turntable 1, thereby adjusting the swing amplitude.

[0024] To sum up: the fully automatic wire harness bending performance test fixture, through the coordinated use of the threaded rod 12 and the threaded tube 11, adjusts the position of the shell 2 on the front side of the test turntable 1, adjusts the bending amplitude, and then inserts the wire harness between the extrusion clamp 3 and the fixed clamp 6, and through the coordinated use of the extrusion pin 4 and the anti-slip assembly 5, causes elastic extrusion to the extrusion clamp 3, so that the wire harness can be clamped and limited, thereby achieving the purposes of quick disassembly and assembly, wide adaptation size and adjustable bending amplitude.
