Description

Technical Field

[0001] The utility model relates to the technical field of electronic wire harness production, and more specifically, to a wire twisting device for electronic wire harness production. Background Art

[0002] In the existing electronic wire harness production technology, wire twisting is a key process. At present, a considerable number of production lines still rely on manual wire twisting. This manual operation method is difficult to ensure the continuity and consistency of production, resulting in low production efficiency and unstable product quality. In addition, workers who engage in such repetitive labor for a long time are prone to fatigue and operational errors, which affects the overall production efficiency and wire harness quality.

[0003] First, the current wire twisting technology has the problem of insufficient adaptability to wire harness diameter. Most wire twisting devices are relatively simple in design and can only adapt to cables within a specific diameter range, and cannot meet the diverse wire harness specification requirements. This design limitation makes it impossible to effectively clamp and twist cables of different diameters, affecting the quality and efficiency of the twisted wires. Secondly, the existing wire twisting devices mostly use a fixed clamping structure, which can only clamp the two ends of the electronic wire harness for twisting. This design cannot achieve continuous production because after each twisting is completed, the new wire harness needs to be manually re-clamped. Such intermittent operations greatly reduce production efficiency, while increasing labor costs and the possibility of operational errors.

[0004] Furthermore, most of the existing stranding devices are fixed structures, which makes the disassembly and adjustment of the stranding machine inconvenient. When the production process changes or equipment needs to be upgraded, the fixed-structure stranding device cannot adapt flexibly, thus affecting the flexibility of the production line and the efficiency of upgrading and transformation. This design not only limits the flexible adjustment of the production line, but also increases the time and economic costs of equipment upgrades and replacements. Utility Model Content

[0031] A pressing plate 11 is provided at one end of the lower pressing plate 8 , and the pressing plate 11 extends outward from the stranding frame 4 .

[0032] A second spring 12 is provided on one side of the pressing plate 11 .

[0033] In this embodiment, when in use, the motor 2 is turned on, and the motor 2 drives the movable frame 3 connected to the output end to rotate, thereby driving the twisting frame 4 to rotate, thereby realizing the function of twisting the wire. When the twisting frame 4 needs to be replaced or upgraded, the pressing plate 11 is pressed, and the pressing plate 11 drives the lower pressing plate 8 to move downward and compresses the second spring 12 set on one side. Then, due to the special structure of the lower pressing plate 8 and the card plate 5, when the pressing plate 11 is pressed downward, the card plate 5 will gradually retract inward and compress the third spring 7 set on one side. When the pressing plate 11 is pressed to the limit, the card plate 5 Just disengage from the card slot 6, and then pull the twist frame 4 directly out of the movable frame 3. After the upgrade is completed, align the plug-in block 9 set on the side of the movable frame 3 with the bottom of the twist frame 4, and then press the twist frame 4 directly to the side of the movable frame 3.

When the plug-in block 9 is completely pushed into the inside of the twist frame 4, the position of the card plate 5 just corresponds to the position of the card slot 6, and then the third spring 7 is reset, thereby pushing the card plate 5 into the card slot 6, so that the twist frame 4 and the movable frame 3 are stably connected together.

[0034] See also Figure 1-4 As a further implementation method of the entire device: a sliding frame 13 is provided at one end of the support frame 1 and the inner side of the twisting frame 4, and a pulley 14 is provided at the corresponding position of the inner side of the sliding frame 13 and the inner side of the twisting frame 4.

[0035] A cylinder 15 is disposed at one end of the support frame 1 , a piston rod 16 is disposed at the output end of the cylinder 15 , and the other end of the piston rod 16 is connected to the corresponding sliding frame 13 .

[0036] Slide blocks 17 are symmetrically arranged on both sides of the sliding frame 13 , and corresponding positions of the stranding frame 4 are provided with slide grooves 18 , in which the slide blocks 17 are slidably installed.

[0038] One end of the sliding frame 13 is connected to an adjusting rod 22 .

[0039] More specifically, before using the device, first pass the single-strand wire through the two pulleys 14 arranged on the inner side of the twisting frame 4, and then push the adjusting rod 22. The adjusting rod 22 will push the sliding frame 13 to move, and at the same time, the sliders 17 arranged on both sides of the sliding frame 13 will slide accordingly in the sliding groove 18. In this process, the ball 19 will slide out of the original positioning groove 21 and squeeze the first spring 20 arranged on one side, causing the first spring 20 to be compressed. Then, when the pulley 14 installed on the inner side of the sliding frame 13 and the pulley 14 at another place clamp the single-strand wire, stop pushing the adjusting rod 22, and then pass the single-strand wire through one end of the support frame 1, and then open the two relatively arranged cylinders 15. The cylinder 15 moves through the slider 17 frame connected to the output end, so that the pulley 14 installed on the inner side of the sliding frame 13 here clamps the multi-strand wire. Then, the single-strand wire can be docked and clamped with another external device in turn.

[0040] In summary, when the overall device is in use or running: when in use, turn on the motor 2, the motor 2 will drive the movable frame 3 connected to the output end to rotate, thereby driving the twisting frame 4 to rotate, and then realize the function of twisting the wire. When the twisting frame 4 needs to be replaced or upgraded, press the pressing plate 11, the pressing plate 11 will drive the lower pressing plate 8 to move downward and compress the second spring 12 set on one side. Then, due to the special structure of the lower pressing plate 8 and the card plate 5, when the pressing plate 11 is pressed down, the card plate 5 will gradually retract inward and compress the third spring 7 set on one side. When the pressing plate 11 is pressed to the limit , the card plate 5 just detaches from the card slot 6, and then the twisting frame 4 is directly pulled out from the movable frame 3. After the upgrade is completed, align the plug-in block 9 set on the side of the movable frame 3 with the bottom of the twisting frame 4, and then press the twisting frame 4 directly to the side of the movable frame 3. When the plug-in block 9 enters the inner side of the twisting frame 4, the card plate 5 will be squeezed and thus close to the outer side of the plug-in block 9. When the plug-in block 9 is completely pushed into the inside of the twisting frame 4, the position of the card plate 5 just corresponds to the position of the card slot 6, and then the third spring 7 is reset, thereby pushing the card plate 5 into the card slot 6, so that the twisting frame 4 and the movable frame 3 are stably connected together.

[0041] Before using the device, first pass the single-strand wire through the two pulleys 14 arranged on the inner side of the twisting frame 4, and then push the adjusting rod 22. The adjusting rod 22 will push the sliding frame 13 to move, and at the same time, the sliders 17 arranged on both sides of the sliding frame 13 will slide accordingly in the sliding groove 18. In this process, the ball 19 will slide out of the original positioning groove 21 and squeeze the first spring 20 arranged on one side, causing the first spring 20 to be compressed. Then, when the pulley 14 installed on the inner side of the sliding frame 13 and the pulley 14 at another place clamp the single-strand wire, stop pushing the adjusting rod 22, and then pass the single-strand wire through one end of the support frame 1, and then open the two relatively arranged cylinders 15. The cylinder 15 moves through the slider 17 frame connected to the output end, so that the pulley 14 installed on the inner side of the sliding frame 13 here clamps the multi-strand wire clamping column, and then the single-strand wire can be docked and clamped with another external device in turn.
