Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire and cable manufacturing technology, and in particular to a stranding device for power cable harnesses. Background Technology
[0002] To meet the ever-increasing demand for wires and cables, stranding machines have seen significant improvements in production speed. New motors and drive systems have been designed to enable the stranding machine to rotate at higher speeds while maintaining stable operation. For example, the use of high-performance servo motors and precision reducers not only increases stranding speed but also reduces noise and vibration during operation.
[0003] In existing technologies, insufficient tension stability of individual strands during the stranding process is a major problem. Stable tension is crucial for cable stranding; unstable tension results in uneven cable tightness after stranding. Current stranding devices exhibit poor control of individual strand tension during both the unwinding and stranding stages. Specifically, the unwinding speed and stranding speed are difficult to precisely match, leading to tension fluctuations, and tension differences can easily occur between different individual strands. These problems negatively impact the overall quality of the cable, degrading its mechanical and electrical properties.
[0004] Therefore, this application provides a power cable harness stranding device to meet the requirements. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wire harness stranding device for power cables.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a power cable harness stranding device, comprising:
[0007] Mounting plate
[0008] A tensioning assembly is disposed inside a mounting plate. The tensioning assembly includes a third fixing plate fixedly connected to the mounting plate. An electric telescopic rod is fixedly connected to the third fixing plate. A sliding column is fixedly connected to the electric telescopic rod. A transmission disc is slidably connected to the sliding column. A first rotating shaft is rotatably connected to the transmission disc. A first transmission rod is rotatably connected to the first rotating shaft. A second rotating shaft is rotatably connected to the first transmission rod.

The third rotating shaft is rotatably connected to the sliding column. A first motor is fixedly connected to the third fixing plate. The first fixing plate is fixedly connected to the first motor.
[0009] A wire feeding assembly is placed inside a mounting plate. The wire feeding assembly includes a mounting compartment fixedly connected to the mounting plate, and a wire feeding roller is rotatably connected to the mounting compartment.
[0010] In a preferred embodiment, the transmission disc is fixedly connected to the mounting plate.
[0011] The beneficial effect of adopting the above-mentioned further solution is that by fixing the transmission disc to the mounting plate, it is avoided that the transmission disc will be displaced when the sliding column rotates.
[0012] In a preferred embodiment, a second motor is installed inside the installation chamber, and the installation chamber is rotatably connected to the wire feeding roller via a fourth rotating shaft, with the output end of the second motor rotatably connected to the fourth rotating shaft.
[0013] The beneficial effect of adopting the above-mentioned further solution is that by setting a second motor, the wire feeding roller can be driven to rotate during use. The second motor has high controllability and can avoid the wire feeding roller from over-feeding.
[0014] In a preferred embodiment, a second fixing plate is fixedly connected to the mounting plate, and both the first fixing plate and the second fixing plate have slots.
[0015] The beneficial effect of adopting the above-mentioned further solution is that by opening slots on the first fixing plate and the second fixing plate, it is convenient to pass cables through the slots during use.
[0016] In a preferred embodiment, an opening is provided on the side of the mounting plate near the first fixing plate.
[0017] The beneficial effect of adopting the above-mentioned further solution is that by opening the hole on the mounting plate, it is convenient to place the twisted cable into the opening and remove it, thus avoiding accumulation inside the mounting plate.
[0018] In a preferred embodiment, the first transmission rod is provided with a placement groove.
[0019] The beneficial effect of adopting the above-mentioned further solution is that by providing a placement groove on the first transmission rod, it is convenient to place the cable during use and to prevent the cable from falling off.
[0020] In a preferred embodiment, the transmission disk has a sliding hole, and the sliding column is slidably connected to the transmission disk through the sliding hole.
[0021] The beneficial effect of adopting the above-mentioned further solution is that by opening a sliding hole on the transmission disc, it is convenient for the sliding column to slide in it during use.
[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0023] 1. In this utility model, regarding tension adjustment, an electric telescopic rod drives a sliding column to slide on a transmission disc. Through the linkage of the first and second transmission rods, the degree of tension or limitation on the cable is cleverly altered, thereby precisely adjusting the cable tension. During operation, the extension and retraction of the electric telescopic rod displaces the sliding column, causing the connected first transmission rod to tilt up or down, thus reducing cable tension or limitation. This effectively solves the problems of tension fluctuations and individual strand tension differences caused by mismatched pay-off and stranding speeds in existing technologies, ensuring uniform tension of the stranded cable and improving its mechanical and electrical performance.
[0024] 2. In this utility model, the wire feeding speed of the wire feeding roller is controlled by the second motor in the installation chamber, which can not only flexibly fine adjust the cable tension, but also prevent overfeeding and enhance tension stability. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0034] like Figure 1-4 As shown, this utility model provides a technical solution: a power cable harness stranding device, comprising:
[0035] Mounting plate 1
[0036] Tensioning assembly 2 is placed inside mounting plate 1. Tensioning assembly 2 includes a third fixing plate 28 fixedly connected to mounting plate 1. An electric telescopic rod 27 is fixedly connected to the third fixing plate 28. A sliding column 211 is fixedly connected to the electric telescopic rod 27. A transmission disk 21 is slidably connected to the sliding column 211. A first rotating shaft 22 is rotatably connected to the transmission disk 21. A first transmission rod 23 is rotatably connected to the first rotating shaft 22. A second rotating shaft 25 is rotatably connected to the first transmission rod 23. A second transmission rod 24 is rotatably connected to the second rotating shaft 25. A third rotating shaft 26 is fixedly connected to the second transmission rod 24. The third rotating shaft 26 is rotatably connected to the sliding column 211. A first motor 29 is fixedly connected to the third fixing plate 28. A first fixing plate 210 is fixedly connected to the first motor 29.
[0037] The wire feeding assembly 3 is placed inside the mounting plate 1. The wire feeding assembly 3 includes a mounting chamber 31 fixedly connected to the mounting plate 1, and a wire feeding roller 32 is rotatably connected to the mounting chamber 31.
[0038] In this invention, for tension adjustment, an electric telescopic rod 27 drives a sliding column 211 to slide on a transmission disc 21. Through the linkage of the first transmission rod 23 and the second transmission rod 24, the degree of tension or limitation on the cable is cleverly changed, thereby precisely adjusting the cable tension. During operation, the extension and retraction of the electric telescopic rod 27 displaces the sliding column 211, causing the connected first transmission rod 23 to tilt up or down, thus reducing cable tension or limitation. This effectively solves the problems of tension fluctuations and individual strand tension differences caused by mismatched pay-off and stranding speeds in existing technologies, ensuring uniform tension of the stranded cable and improving its mechanical and electrical performance.
[0039] Furthermore, such as Figures 1 to 4 As shown, the transmission disc 21 is fixedly connected to the mounting plate 1. By fixing the transmission disc 21 to the mounting plate 1, it is prevented that the transmission disc 21 will be displaced when the sliding column 211 rotates.
[0040] The mounting chamber 31 is equipped with a second motor 34. The mounting chamber 31 is rotatably connected to the wire feeding roller 32 via a fourth rotating shaft 35. The output end of the second motor 34 is rotatably connected to the fourth rotating shaft 35. By providing the second motor 34, the wire feeding roller 32 can be driven to rotate during use. The second motor 34 has high controllability and can prevent the wire feeding roller 32 from over-feeding.
[0041] A second fixing plate 33 is fixedly connected to the mounting plate 1. Both the first fixing plate 210 and the second fixing plate 33 have slots. The slots on the first fixing plate 210 and the second fixing plate 33 facilitate the threading of cables during use.
[0042] An opening is provided on the side of the mounting plate 1 near the first fixing plate 210. By providing an opening on the mounting plate 1, it is convenient to place the twisted cable into the opening and remove it, thus avoiding accumulation inside the mounting plate 1.
[0043] The first transmission rod 23 is provided with a placement groove, which makes it convenient to place cables during use and prevents cables from falling off.
[0044] like Figure 2 as well as Figure 3 As shown, a sliding hole is provided on the transmission disk 21, and the sliding column 211 is slidably connected to the transmission disk 21 through the sliding hole on the transmission disk 21. By providing a sliding hole on the transmission disk 21, it is convenient for the sliding column 211 to slide in it during use.
[0045] Working principle: such as Figure 1-4 As shown,
[0046] In use, first, the cable is placed on the cable release roller 32, the second motor 34 is started to rotate slowly, and the staff pulls out the cable and passes it through the second fixing plate 33, the placement slot on the first transmission rod 23 and the first fixing plate 210 in sequence to complete the installation of the cable.
[0047] During normal use, starting the first motor 29 causes the first fixed plate 210 to rotate, performing the cable twisting process. During this process, the cable is pulled by the second fixed plate 33 and the first transmission rod 23 to complete the twisting.
[0048] When it is necessary to adjust the cable tension, the electric telescopic rod 27 is activated, causing the sliding column 211 to slide on the side of the transmission plate 21 closer to the cable feeding assembly 3. This causes the second transmission rod 24 to drive the first transmission rod 23 to tilt up and stretch the cable. When the sliding column 211 slides away from the cable feeding assembly 3, the second transmission rod 24 will drive the first transmission rod 23 to move downward, thus weakening the restriction of the first transmission rod 23 on the cable.
[0049] During the wire laying process, the wire laying speed of the wire laying roller 32 can be controlled by the second motor 34, which can also achieve slight adjustment of the cable tension.
[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
