Description

Technical Field

[0001] This utility model relates to the field of bending test technology, specifically to a limiting mechanism for testing the bending resistance of wire harnesses. Background Technology

[0002] As a key connecting component of electrical equipment, the bending resistance of wire harnesses directly affects the service life and reliability of the equipment. Therefore, bending resistance tests are required to inspect their quality during the production process.

[0003] The wire bending tester is the main equipment for testing the bending resistance of wire harnesses. During the test, it is necessary to use a limiting mechanism to position and constrain the wire harness to ensure that the wire harness is tested according to the preset bending path and angle, so as to avoid deviation of the test results due to wire harness displacement. The limiting mechanism used in existing wire harness bending resistance testing machines is mostly a threaded handle that drives two clamping plates to move in opposite directions to clamp the wire harness. This clamping method not only has a poor effect on fixing and limiting the wire harness, but also makes the whole clamping process cumbersome. When testing multiple wire harnesses at the same time, it is necessary to frequently turn the bolts and tighten them, which is time-consuming and labor-intensive. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a limiting mechanism for testing the bending resistance of wire harnesses.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a wire bending test machine, wherein multiple clamping structures are installed and fixed on the wire bending test machine; The clamping structure includes a fixed frame and a movable frame; One end of the fixed frame is slidably connected to a movable insert frame via a slider. Multiple limiting plates are inserted and fitted inside the movable insert frame. The other end of the movable insert frame is connected to and fixed with a limiting plate, and a positioning insert frame is inserted and fitted on the limiting plate.

[0006] Furthermore, the positioning insert frame is slidably connected to the moving frame via a slider. The groove at one end of the moving frame has a trapezoidal structure. The moving insert frame is rotatably connected to one end of the fixed frame. The trapezoidal structure at one end of the moving frame facilitates small-angle rotation of the moving frame, which is convenient for clamping the wire harness.

[0007] Furthermore, the limiting plate has a stepped structure, and the positioning insert frame is engraved with scales. The stepped structure of the limiting plate allows it to smoothly move towards the fixed frame to clamp the wire harness when the positioning insert frame is inserted into it.

[0008] The beneficial effects of this utility model are as follows: When limiting the wire harness, firstly, according to the thickness of the wire harness and the scale on the positioning frame, the moving frame at the end of the moving frame can be controlled in advance to move the corresponding distance and insert it into the limiting plate. Since the groove at one end of the moving frame has a trapezoidal structure, the moving frame can rotate a small angle, so the wire harness can be conveniently placed between the fixed frame and the moving frame. Then, the positioning frame is controlled to move and insert into the limiting plate. Since the limiting plate has a stepped structure, when the positioning frame moves to the middle of the limiting plate, it will abut against the limiting plate and move towards the fixed frame, thus clamping the wire harness. This operation avoids the problem of frequent bolt tightening and tightening when clamping the wire harness in the prior art, which is time-consuming and laborious.

[0009] Furthermore, the movable insert frame has multiple insertion slots inside, and the ends of the insertion slots have chamfers. The limiting insert plate is inserted into the insertion slots, and the chamfers at the ends of the insertion slots facilitate the insertion of the limiting insert plate into the insertion slots.

[0010] Furthermore, the inner wall of the positioning frame is provided with multiple positioning slots, which are inserted and engaged with the limiting plate.

[0011] Furthermore, a latch is slidably connected inside the limiting plate. A spring is fixedly connected to the end of the latch, and a pressing rod is fixedly connected to the end of the latch. The pressing rod is slidably connected to the fixed frame. The latch engages with the positioning slot. The other end of the spring is fixedly connected to the fixed frame. When the positioning frame and the limiting plate are inserted into place, the positioning frame will abut against the latch on the limiting plate. This will cause the latch and the pressing rod to compress the spring and move. After the positioning frame and the limiting plate are inserted into place, the spring will cause the latch to engage with the positioning slot inside the positioning frame. This ensures the stability of the wire during bending. When the wire needs to be removed, the pressing rod only needs to compress the spring to separate the latch from the positioning slot, thus removing the positioning frame on the limiting plate and the wire harness.

In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0019] Example 1 Figure 1 A structural diagram of a limiting mechanism for testing the bending resistance of a wire harness, as provided in this embodiment of the utility model, is shown below. Figure 1 , Figure 2 and Figure 3 As shown, a wire bending test machine 1 is equipped with multiple clamping structures 2. The clamping structure 2 includes a fixed frame 21 and a movable frame 22. One end of the fixed frame 21 is slidably connected to a movable insert frame 23 via a slider. Multiple limiting plates 24 are inserted and fitted inside the movable insert frame 23. The other end of the movable insert frame 23 is connected to and fixed to a limiting plate 25, and a positioning insert frame 26 is inserted and fitted on the limiting plate 25.

[0020] The positioning frame 26 is slidably connected to the movable frame 22 via a slider. One end of the movable frame 22 has a trapezoidal groove. The movable frame 23 is rotatably connected to one end of the fixed frame 21. The trapezoidal groove at one end of the movable frame 22 facilitates small-angle rotation of the movable frame 22, which is convenient for clamping the wire harness.

[0021] The limiting plate 25 has a stepped structure, and the positioning frame 26 has scales. The stepped structure of the limiting plate 25 allows it to smoothly move towards the fixing frame 21 to clamp the wire harness when the positioning frame 26 is inserted into it.

[0022] Example 2 Based on Embodiment 1, the present invention can be further improved in the following ways, such as... Figure 4 and Figure 5 As shown, the movable insert frame 23 has multiple insertion slots 231 inside, and the ends of the insertion slots 231 are chamfered. The limiting insert plate 24 is inserted into the insertion slots 231. The chamfer at the ends of the insertion slots 231 facilitates the insertion of the limiting insert plate 24 into the insertion slots 231.

[0023] The inner wall of the positioning frame 26 is provided with multiple positioning slots 261, which are inserted and engaged with the limiting plate 25.

[0024] A latch 251 is slidably connected inside the limiting plate 25. A spring 252 is fixedly connected to the end of the latch 251, and a pressing rod 253 is fixedly connected to the end of the latch 251. The pressing rod 253 is slidably connected to the fixed frame 21. The latch 251 engages with the positioning slot 261. The other end of the spring 252 is fixedly connected to the fixed frame 21. When the positioning insert 26 is inserted into the limiting plate 25, the positioning insert 26 will abut against the latch 251 on the limiting plate 25, thus causing... The movable latch 251, together with the pressing rod 253, compresses the spring 252 and moves. Then, after the positioning frame 26 and the limiting plate 25 are inserted into place, the spring 252 drives the latch 251 to engage with the positioning slot 261 in the positioning frame 26. This ensures the stability of the wire during bending. When the wire needs to be removed, simply press the rod 253 to compress the spring 252 to separate the latch 251 from the positioning slot 261, and the positioning frame 26 on the limiting plate 25 can be removed to take off the wire harness.

[0025] Working principle: When limiting the wire harness, firstly, according to the thickness of the wire harness and the scale on the positioning frame 26, the moving frame 23 at the end of the moving frame 22 can be controlled to move a corresponding distance and then insert into the limiting plate 24. Since the groove at one end of the moving frame 22 has a trapezoidal structure, the moving frame 22 can rotate a small angle, so the wire harness can be conveniently placed between the fixed frame 21 and the moving frame 22. Then, the positioning frame 26 is controlled to move and insert into the limiting plate 25. Since the limiting plate 25 has a stepped structure, when the positioning frame 26 moves to the middle of the limiting plate 25, it will abut against the limiting plate 25 and move towards the fixed frame 21, so as to clamp the wire harness. During the insertion of the positioning frame 26 and the limiting plate 25, the positioning frame 26 will abut against the latch 251 on the limiting plate 25. This will cause the latch 251, together with the pressing rod 253, to compress the spring 252 and move. After the positioning frame 26 and the limiting plate 25 are inserted into place, the spring 252 will cause the latch 251 to engage with the positioning slot 261 in the positioning frame 26. This ensures the stability of the wire during bending. When the wire needs to be removed, simply press the rod 253 to compress the spring 252 to separate the latch 251 from the positioning slot 261, and the positioning frame 26 on the limiting plate 25 can be removed to take off the wire harness.
