Description
Technical Field
[0001] This utility model relates to the technical field of metal clip testing tools, and in particular to a life testing fixture for metal clips. Background Technology
[0002] Metal clips are a common and practical tool. They are usually composed of two thin metal pieces that are firmly connected at one end by riveting or welding to form the fixed end of the clip, while the other end serves as the movable clamp. The overall shape of the metal clip is long and narrow, and the size of the metal clip can vary depending on the specific use and design. Metal clips have a wide range of applications in daily life and industrial production.
[0003] The lifespan of metal clips is a key indicator of their quality. However, there is currently a lack of effective tools on the market specifically designed for testing the lifespan of metal clips. Traditional testing methods often rely on manual operation, estimating lifespan by repeatedly opening and closing the clips. Manual operation makes it difficult to ensure consistency in parameters such as force, angle, and speed for each opening and closing, resulting in inaccurate test results with large errors. In addition, manual testing is inefficient, especially for mass-produced metal clips, and cannot meet the needs for rapid and accurate testing. Furthermore, long-term repetitive operation can easily lead to fatigue of the testing personnel, further affecting the testing quality and hindering the testing of metal clip lifespan.
[0004] Therefore, there is an urgent need to improve the life testing fixture for metal clips in order to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of this invention is to provide a life testing fixture for metal clips. A motor drives a bidirectional lead screw to rotate in both directions, thereby causing the first and second rubber blocks to press and release the metal clips. This allows for repeated opening and closing of the metal clips. A force sensor controls the force and collects the force value during the metal clip testing, ensuring the accuracy of the metal clip life testing results.

[0007] The outer walls of the two slide rods are slidably connected to a first slider and a second slider. Both the first slider and the second slider are threadedly connected to the bidirectional lead screw. The first slider is located at one end of the base plate near the first support plate. The first slider and the second slider are symmetrically distributed about the center of the bidirectional lead screw.
[0008] A second connector is fixedly connected to the upper surface of the second slider. A force sensor is fixedly connected to one side of the second connector. A second rubber block is fixedly connected to the side of the force sensor away from the second connector. The opening of the second rubber block faces the side of the second slider closer to the first slider.
[0009] A first connector is fixedly connected to the upper surface of the first slider, and a first rubber block is fixedly connected to one side of the first connector. The opening of the first rubber block faces the side of the first slider closer to the second slider, and the first rubber block is flush with the second rubber block.
[0010] Preferably, a fastener is fixedly connected to the upper surface of the control box, and a wing bolt is threadedly connected to one side of the fastener.

A motor 5 is fixedly connected to the side of the mounting plate 3 away from the base plate 2. A second support plate 6 is fixedly connected to the upper side of the base plate 2. Two sliding rods 7 are fixedly connected to the side of the second support plate 6 that is close to the first support plate 4, and a bidirectional lead screw 8 is rotatably connected. One end of the bidirectional lead screw 8 passes through the second support plate 6 and is fixedly connected to the output end of the motor 5. The control box 1 is used to support the base plate 2, the fixing member 15, and the limiting plate 18. The base plate 2 is used to install the first support plate 4, the second support plate 6, and the mounting plate 3. The first support plate 4 and the second support plate 6 are used to support the sliding rods 7 and the bidirectional lead screw 8. The mounting plate 3 is used to install the motor 5. The motor 5 is used to drive the bidirectional lead screw 8 to rotate forward and backward. The bidirectional lead screw 8 is used to drive the first slider 901 and the second slider 902 to move closer to each other and further away from each other.
[0023] Secondly, such as Figure 1 , Figure 3 as well as Figure 4 As shown, the outer walls of the two slide rods 7 are slidably connected to a first slider 901 and a second slider 902. Both the first slider 901 and the second slider 902 are threadedly connected to the bidirectional lead screw 8. The first slider 901 is located at one end of the base plate 2 near the first support plate 4. The first slider 901 and the second slider 902 are symmetrically distributed about the center of the bidirectional lead screw 8. The first slider 901 is used to support the first connecting piece 10 and the first rubber block 11, and the second slider 902 is used to support the second connecting piece 12, the force sensor 13, and the second rubber block 14.
[0024] Furthermore, such as Figure 1 as well as Figure 3 As shown, a second connector 12 is fixedly connected to the upper surface of the second slider 902. A force sensor 13 is fixedly connected to one side of the second connector 12. A second rubber block 14 is fixedly connected to the side of the force sensor 13 away from the second connector 12. The opening of the second rubber block 14 faces the side of the second slider 902 closer to the first slider 901. A first connector 10 is fixedly connected to the upper surface of the first slider 901. A first rubber block 11 is fixedly connected to one side of the first connector 10. The opening of the first rubber block 11 faces the side of the first slider 901. At a position near the second slider 902 on block 901, the first rubber block 11 and the second rubber block 14 are flush. The first connector 10 is used to support the first rubber block 11. The first rubber block 11 is used to cooperate with the second rubber block 14 to detect the metal clip 100. The second connector 12 is used to install the support force sensor 13. The force sensor 13 is used to detect and collect the force value, and to install and support the second rubber block 14. The second rubber block 14 cooperates with the first rubber block 11 to press and release the metal clip 100.
[0025] Furthermore, such as Figure 1 , Figure 2 as well as Figure 3As shown, a fastener 15 is fixedly connected to the upper surface of the control box 1. A wing bolt 16 is threaded onto one side of the fastener 15. A rubber pad 17 and a metal clip 100 are fitted onto the outer wall of the wing bolt 16. The metal clip 100 is located between the rubber pad 17 and the fastener 15. The two sides of the rubber pad 17 abut against the metal clip 100 and the wing bolt 16, respectively. Multiple connection holes 19 are provided on the upper surface of the control box 1. The connection holes 19 are perpendicular to one side of the base plate 2 and are located on the side of the base plate 2 closest to the fastener 15. The fastener 15 is used to support and fix the fixed end of the metal clip 100. The wing bolt 16 and the rubber pad 17 are used to fix the fixed end of the metal clip 100 to the fastener 15, which facilitates the fixing of the metal clip 100 and improves the efficiency of fixing the metal clip 100. The connection holes 19 are used to fix the fastener 15 and can adjust the relative distance between the fastener 15 and the base plate 2, which is suitable for testing metal clips of different lengths.
[0026] Furthermore, such as Figure 1 , Figure 3 as well as Figure 4 As shown, a limiting plate 18 is fixedly connected to the upper surface of the control box 1. The limiting plate 18 is parallel to one side of the base plate 2. The limiting plate 18 is located on the side of the base plate 2 away from the fixing member 15. The limiting plate 18 is used to support the open end of the metal clip 100 and prevent interference from occurring after the metal clip hangs down.
[0027] like Figure 1 - Figure 4 As shown, the principle of the metal clip life testing fixture provided in this embodiment is as follows: When using this metal clip life testing fixture to test the life of a metal clip, firstly, after disassembling the wing bolt 16, the metal clip 100 is fitted onto the wing bolt 16, and then the wing bolt 16 is installed onto the fixing member 15. The angle of the metal clip 100 is adjusted to ensure that the first rubber block 11 and the second rubber block 14 can act on both sides of the metal clip 100. The wing bolt 16 is tightened to compress the rubber pad 17, and the rubber pad 17 and the fixing member 15 are used to fix the fixed end of the metal clip 100. The output of motor 5 drives the bidirectional lead screw 8 to rotate in the forward or reverse direction. The bidirectional lead screw 8 drives the first slider 901 and the second slider 902 to move closer or further apart. The first slider 901 drives the first connecting piece 10 and the first rubber block 11 to move. The second slider 902 drives the second connecting piece 12, the force sensor 13 and the second rubber block 14 to move. When the second rubber block 14 and the force sensor 13 press the metal clip 100 together, the force sensor 13 detects the force and collects feedback to ensure the accuracy of the detection of the metal clip 100.
