Description

Technical Field

[0001] This utility model relates to the field of parallel wiring device technology, specifically to a parallel wiring device for shielded braided tin braiding used in communication. Background Technology

[0002] A shielding mesh is a metal braided layer used in cables or electronic equipment. It is mainly used to provide electromagnetic shielding (EMI) and radio frequency interference (RFI) protection, while also enhancing the mechanical strength of the cable. The main materials are tinned copper wire, bare copper wire, aluminum-magnesium alloy wire, etc. When weaving a shielding mesh with tinned copper wire, multiple thin tinned copper wires are combined into one strand to further increase the shielding effect of the braided layer.

[0003] Most existing tin-plated copper wire braiding and twisting devices require the twisting die to be fixedly installed on the relevant drive structure first, and then the positioning mechanism to be adjusted to position the die, so as to achieve the purpose of twisting and stranding multiple fine tin-plated copper wires. However, in actual production, the number of fine tin-plated copper wires twisted will change according to relevant requirements. At this time, it is time-consuming and laborious to replace the twisting die, which seriously reduces production efficiency and also increases the operating burden on the staff.

[0027] 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 scope of protection of the present utility model.

[0028] like Figure 1-5 As shown, a communication shielded braided tin braiding parallel wire device is provided.

[0029] The system includes a base 1, a limiting base 2 on top of the base 1, a limiting top seat 4 movably mounted on top of the limiting base 2, and the inner sides of the limiting base 2 and the limiting top seat 4 together forming a circular groove. The top of the limiting top seat 4 has a rectangular groove communicating with the circular groove. A support base 5 is located at the center of the top of the limiting top seat 4. A drive gear 6 is rotatably mounted inside the support base 5. A paralleling disc 7 is rotatably mounted inside the circular groove. A driven gear ring 8, meshing with the drive gear 6, is arranged around the outer side of the paralleling disc 7. The inner wall of the circular groove... A limiting annular groove 10 is provided around the driven gear ring 8 to limit its movement. Anti-friction arc grooves 11 are symmetrically provided on the inner walls of the limiting base 2 and the limiting top seat 4, with the anti-friction arc grooves 11 located on both sides of the limiting annular groove 10. Ball bearings 12 for supporting the paralleling disc 7 are movably arranged inside the anti-friction arc grooves 11. Fixed guide rods 3 for connecting the limiting top seat 4 are symmetrically provided at both ends of the top of the limiting base 2. Nuts for fixing the limiting base 2 and the limiting top seat 4 are provided on the fixed guide rods 3. The limiting base 2 is welded to the top of the base 1. The limiting base 2 and the limiting top seat 4 connected by four fixed guide rods 3 together form a circular groove with a diameter of Φ200mm. A bracket 5 is welded to the center of the top of the limiting top seat 4, and a drive gear 6 (module 2, number of teeth 30) is installed inside it through a bearing. A wire paralleling disc 7 (material 45# steel) is coaxially installed in the circular groove. A driven gear ring 8 with module 2 is integrally formed on the outer edge of the wire paralleling disc 7, which meshes with the drive gear 6 to form a transmission. The limiting ring groove 10 forms an axial limit on the driven gear ring 8, ensuring that the wire paralleling disc 7 rotates safely. For stability, two symmetrical anti-friction arc grooves 11 are opened on the inner walls of the limiting base 2 and the limiting top seat 4. GCr15 steel balls 12 with a diameter of 5mm are embedded in the grooves with a spacing of 10mm. They contact the end face of the paralleling disc 7 to form rolling support, which is used to reduce the friction when the paralleling disc 7 rotates. The limiting top seat 4 can be quickly disassembled and installed by fixing the guide rod 3 and the nut. When replacing the paralleling disc 7, the limiting top seat 4 can be removed directly, and the driven toothed ring 8 on the newly installed paralleling disc 7 can be inserted into the limiting ring groove 10 to achieve positioning, which is convenient and quick.

[0030] In this embodiment, specifically, threaded grooves are provided at the four corners of the base 1. The base 1 is made of Q235 steel. The threaded grooves at the four corners are used for fixed installation. The interior of the limiting ring groove 10 and the anti-friction arc groove 11 is filled with grease. The grease filled in the limiting ring groove 10 and the anti-friction arc groove 11 is lithium molybdenum disulfide grease (operating temperature -20℃ to 150℃). This ensures that the driven toothed ring 8 rotates smoothly in the limiting ring groove 10. At the same time, the grease and the ball 12 form a composite lubrication system, reducing the coefficient of friction to below 0.05. Under continuous operation conditions, the axial movement of the parallel plate 7 is less than 0.1mm, and the service life exceeds 8000 hours.

[0031] In this embodiment, specifically, the parallel cable reel 7 is provided with cable grooves 9 for limiting the movement of the cables.

[0032] In this embodiment, specifically, sleeve seats 13 are symmetrically arranged at the outlet end of the parallel cable reel 7. Support rods 14 are movably sleeved inside the sleeve seats 13. A first fixing valve 15 is provided on the sleeve seats 13 to fix the support rods 14. A compression sleeve 16 is provided between the sleeve seats 13. The compression sleeve 16 has through holes for compressing the stranded cables. Two sleeve seats 13 (inner diameter Φ20mm) are welded to the outlet end of the parallel cable reel 7. Telescopic support rods 14 are inserted into the sleeve seats 13 and locked in position by the first fixing valve 15. The compression sleeve 16 is mounted at the end of the two support rods 14. It has through holes with a taper of 1:5 (inlet Φ8mm, outlet Φ5mm). This design can apply an adjustable radial pressure of 20-50N to the combined wire harness. With the speed adjustment of the servo motor 18 (accuracy ±1r / min), the tension fluctuation of the parallel cable is ensured to be less than 5%, effectively preventing wire breakage or loosening.

[0033] In this embodiment, specifically, a gearbox 17 is provided on one side of the mounting base 5, and a reduction gear set is provided inside the gearbox 17. The output end of the reduction gear set is connected to the drive gear 6. A servo motor 18 is provided on the top of the gearbox 17 and is connected to the input end of the reduction gear set. A fixing side plate 19 for fixing the servo motor 18 is provided on the top of the mounting base 5. The gearbox 17 (reduction ratio 10:1) is installed on the side of the mounting base 5. Its output shaft is connected to the drive gear 6, and its input end is connected to the servo motor 18 (power 0.75kW, rated speed 3000r / min) through a coupling. The servo motor 18 is fixed to the fixing side plate 19 by bolts.

[0034] In this embodiment, specifically, a sleeve rod 20 is provided on the top of the base 1, and the sleeve rod 20 is close to the cable outlet end of the cable reel 7. A lifting rod 21 is movably sleeved inside the sleeve rod 20. A second fixing valve 22 for fixing the lifting rod 21 is provided on the sleeve rod 20. A wheel seat 23 is provided at the top of the lifting rod 21. Two sets of guide wheels 24 are rotatably arranged inside the wheel seat 23, and the guide wheels 24 are symmetrically distributed vertically. The stranded cable passes through the two sets of guide wheels 24. The movement of the cable is guided and limited by the two sets of guide wheels 24, which ensures the stability of the cable during winding. The lifting rod 21 is sleeved in the sleeve rod 20 to adjust the height of the guide wheels 24.
