Description

Technical Field

[0001] This utility model relates to the field of wire testing equipment, and in particular to a wire bending resistance testing machine. Background Technology

[0002] As a core component for power transmission and signal conduction, the bending resistance of wires directly affects the reliability and service life of electronic products, automotive wiring harnesses, aerospace equipment, and other fields. With the rapid development of industries such as new energy vehicles, 5G communication, and flexible electronics, the types of wires are becoming increasingly diversified (such as ultra-fine coaxial cables, multi-core shielded wires, and stretchable wire harnesses), which places higher demands on the accuracy, efficiency, and versatility of bending resistance testing equipment.

[0003] Most existing equipment uses manual clamping devices to hold the copper wire inside the wire for testing. This cannot simultaneously hold the copper wire component of the wire while holding the outer insulation wire. When fixing and adjusting the wire at the bottom, the height of the bottom fixing component is usually adjusted by rotating screws to accommodate the length of the test wire. However, this adjustment requires professional tools, which is very time-consuming and labor-intensive. Therefore, a wire bending resistance testing machine is proposed to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a wire bending resistance testing machine, which aims to improve the problems of the existing technology where the manual clamping method cannot simultaneously and stably fix the wire insulation layer and the internal copper wire components, resulting in poor clamping reliability, easy damage to the wire, and the reliance on professional tools for adjusting the height of the bottom fixing component, which is cumbersome and inefficient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Multiple evenly distributed fixed rods are slidably connected to opposite sides of each support rod. A knob is fixedly connected to the front of each threaded rod. A wire-fixing block is fixedly connected to the rear of each threaded rod. A fixed block is fixedly connected to the top of each wire-fixing block. An expansion groove is opened inside the fixed block. An expansion rod is slidably connected inside the fixed block. A spring is fixedly connected to the front of the expansion rod. A wire-clamping plate is fixedly connected to the rear of the expansion rod.

[0007] As a further description of the above technical solution:

[0008] The support frame has a sliding groove one on one side facing each other, a sliding groove two on the front of the support frame, and multiple evenly distributed support grooves on the front inner side of the support frame. A fixed rod two is slidably connected to the bottom of the support frame on one side facing each other, and a fixed hole is opened at the front of the fixed rod two. A telescopic rod two is slidably connected to the front of the support frame, and a spring two is slidably connected to the outer periphery of the telescopic rod two. Multiple evenly distributed support blocks are fixedly connected to the front of the support frame.

[0009] As a further description of the above technical solution:

[0010] The two fixed rods are fixedly connected to the two connecting blocks on one side of the fixed rods. The two connecting blocks are fixedly connected to the two supporting rods on both the front and back sides of the two connecting blocks.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the wire fixing block, spring 1, telescopic rod and wire clamping plate achieve synchronous and stable fixing of the wire insulation layer and the internal copper wire. Under the elastic force of spring 1, the wire clamping plate can simultaneously press against the outer surface of the insulation layer and the stripped copper wire, avoiding the wire slippage or insulation layer tearing caused by traditional manual clamping that only fixes the copper wire. The adaptive compensation function of the spring can automatically adjust the clamping force according to the wire diameter, effectively solving the problem of copper wire flattening caused by local overpressure, and significantly improving the clamping accuracy and wire protection effect.

[0023] 2. In this utility model, through the cooperation of the sliding groove, telescopic rod, spring and support block, the fixed rod can be pushed and pulled by hand in the sliding groove. The slot structure between the telescopic rod and the support block achieves quick positioning without the need for any tools. The spring preload ensures that the fixed rod does not show any signs of loosening during the test, avoiding test interruption caused by reliance on adjustment tools or vibration loosening, and significantly reducing the intensity of manual operation and time cost.

A base plate 2 is fixedly connected to the bottom of the equipment box 1, maintaining stability during equipment operation. Support frames 7 are fixedly connected to the top left and right sides of the base plate 2, symmetrically distributed, for supporting and fixing components, providing an installation carrier for the mechanical structure of the wire bending test. Connecting rods 5 are rotatably connected to opposite sides of each support frame 7. A limit block 6 abuts against the right side of each support frame 7, limiting the rotation angle range. Connecting blocks 8 are fixedly connected to opposite sides of each connecting rod 5. Support rods 9 are fixedly connected to the front and rear of opposite sides of each connecting block 8. The connecting blocks 8 and support rods 9 cooperate to provide a fixed carrier for the connected components. Multiple evenly spaced branches are opened at the front of each support rod 9. The support rod 9 has multiple evenly distributed threaded rods 10 threadedly connected to the threaded hole 12 of the cloth. Multiple evenly distributed fixing rods 11 are slidably connected to the support rod 9 on the opposite side. A knob 13 is fixedly connected to the front of each threaded rod 10. Rotating the knob 13 causes the threaded rod 10 to rotate within the threaded hole 12, allowing the wire-fixing block 14 to move along the axis, thus fixing the wire. The wire-fixing block 14 is fixedly connected to the rear of each threaded rod 10, serving to fix the wire. A fixing block 15 is fixedly connected to the top of the wire-fixing block 14. A telescopic groove 16 is provided inside the fixing block 15. A telescopic rod 18 is slidably connected inside the fixing block 15. A spring 17 is fixedly connected to the front of the telescopic rod 18, and a clamping plate 19 is fixedly connected to the rear of the telescopic rod 18. Through the telescopic groove 16 inside the fixing block 15, the telescopic rod 18 can slide within it, thereby pushing the clamping plate 19 to adaptively clamp the copper wire component of the wire.

A fixing rod 23 is slidably connected to the bottom of the opposite side of the support frame 7. A fixing hole 24 is provided at the front of the fixing rod 23. A telescopic rod 26 is slidably connected to the front of the support frame 7. The telescopic rod 26 passes through the fixing hole 24 and is inserted into the support groove 22 to lock the position of the fixing rod 23. A spring 25 is slidably connected to the outer periphery of the support frame 7, providing elastic support and achieving an adaptive effect. Multiple evenly distributed support blocks 27 are fixedly connected to the front of the support frame 7. After the telescopic rod 26 is fixed, the support blocks 27 support the telescopic rod 26 and prevent it from sliding down. A connecting block 28 is fixedly connected to the opposite side of the fixed rod 23. Support rods 29 are fixedly connected to the front and back of the opposite side of the connecting block 28. Multiple evenly distributed wire fixing tubes 30 are slidably connected to the outer periphery of the support rod 29. The connecting block 28 cooperates with the support rod 29 to allow the wire fixing tubes 30 to slide on its outer periphery, thereby fixing the position of the bottom wire.

[0034] Reference Figures 1-5 In one embodiment of this utility model: Connecting rod 4 is fixedly connected to the left side of connecting rod 5, which serves as a connector to ensure more stable and secure rotation. Limiting block 6 is fixedly connected to the right side of another connecting rod 5. Fixing rod 11 is fixedly connected to the front of fixing block 14, parallel to threaded rod 10, with both ends inserted into the sliding holes of support rod 9, forming a double-guided support for fixing block 14 to prevent deflection of fixing block 14 when threaded rod 10 rotates, thus affecting clamping accuracy. Threaded rod 10 is threadedly connected within threaded hole 12, allowing threaded rod 10 to... The telescopic rod 18 is slidably connected to the telescopic groove 16, and the other end of the spring 17 is fixedly connected to the telescopic groove 16. Both the spring 17 and the telescopic rod 18 are confined within the telescopic groove 16 for movement. The telescopic rod 26 is slidably connected to the support groove 22. The telescopic rod 26 and the support groove 22 cooperate to achieve the fixing function. The telescopic rod 26 abuts against the top of the support block 27. The support block 27 also serves to fix the telescopic rod 26. The telescopic rod 26 is slidably connected to the fixing hole 24. The spring 25 is set in the sliding groove 21. The fixing rod 23 is slidably connected to the sliding groove 20.

[0035] Working principle: When conducting the wire bending resistance test, firstly, rotate the threaded rod 10 by knob 13, which drives the wire fixing block 14 to move axially along the support rod 9, thereby adjusting the clamping plate 19 to a suitable horizontal position. Then, strip the insulation layer from one end of the wire to expose the copper wire part, and place it in the clamping area between the clamping plate 19 and the fixing block 15. Then, rotate the threaded rod 10 to clamp the two parts of the wire. After the motor 3 starts, it drives the connecting rod 4 to rotate, which in turn drives the connecting rod 5 to rotate around the support frame 7. The connecting rod 5 drives the support rod 9 to swing back and forth through the connecting block 8, causing the end of the wire clamped by the clamping plate 19 to perform a periodic bending motion. The fixing rod 11 is set parallel to the threaded rod 10 to assist in supporting the wire fixing block 14, preventing skewing during swinging, and ensuring that the bending action is smooth and the angle is accurate.

[0036] The other end of the wire passes through the fixing tube 30. The fixing tube 30 and the support rod 29 slide together to achieve initial positioning at the bottom. When the length of the wire needs to be adjusted, the operator pulls the telescopic rod 26 upward by hand, compressing the spring 25 and disengaging the end of the telescopic rod 26 from the support groove 22. At this time, the fixed rod 23 can slide freely up and down in the sliding groove 20. After the fixed rod 23 is moved to the target height, the telescopic rod 26 is released. The spring 25 returns to its original position and pushes the telescopic rod 26 into the support groove 22 at the corresponding height, achieving quick locking of the fixed rod 23. The support block 27 provides a support fulcrum for the telescopic rod 26 to prevent slippage and loosening caused by vibration, ensuring the stability of the bottom fixed position.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
