Description

Technical Field

[0001] This utility model relates to the technical field of core cabling positioning devices, specifically to a positioning device for core cabling. Background Technology

[0002] In the process of cable making, multiple cores need to be twisted together in a certain way to form a cable with specific properties. In this process, the positioning accuracy and tension control of the cores are crucial, directly affecting the structural stability, electrical performance and mechanical performance of the cable.

[0003] A search revealed that patent document CN212032759U discloses a cable core positioning device for a cabling machine, comprising a positioning bushing, a positioning core, and a main board. The positioning core is mounted on the positioning bushing, and the main board is vertically mounted on it. The main board is equipped with a five-wheel straightening assembly for straightening and guiding the cable cores. The five-wheel straightening assembly includes two arc wheels and three corner wheels. This invention can realize functions such as straightening and guiding the cable cores.

[0004] The aforementioned existing technologies often have the following problems when used: Existing core cabling positioning devices have fixed positioning component sizes, which cannot adapt to cores of different diameters and have poor versatility. At the same time, the tension of the cores is unstable during the cabling process, which can easily lead to slack or overstretching, resulting in uneven stranding of the cores and affecting cable quality. In addition, some positioning devices have unreasonable structural designs, which can easily cause friction and wear to the cores when they pass through the positioning components, reducing the service life of the cores. Corresponding solutions are needed. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a positioning device for core cabling, which can effectively solve the problems of poor versatility, unstable tension control and easy wear of cores in the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a positioning device for core cable assembly, including a support base. A motor is fixedly connected to the side wall of the support base via a bracket. A rotating shaft is fixedly connected to the output end of the motor. The rotating shaft is rotatably connected to the side wall of the support base via a bearing. A first turntable is provided above the support base. A connecting column is fixedly connected to the side wall of the first turntable. A second turntable is fixedly connected to the side end of the connecting column.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Example: Refer to Figures 1 to 4 A positioning device for core cabling includes a support base 1. A motor 11 is fixedly connected to the side wall of the support base 1 via a bracket. A rotating shaft 12 is fixedly connected to the output end of the motor 11. The rotating shaft 12 is rotatably connected to the side wall of the support base 1 via a bearing. A first turntable 13 is provided above the support base 1. A connecting column 14 is fixedly connected to the side wall of the first turntable 13. A second turntable 15 is fixedly connected to the side end of the connecting column 14. The first turntable 13, the connecting column 14, and the second turntable 15 are all circumferentially fixedly connected to the rotating shaft 12. A reinforcing column 16 is fixedly connected to the side wall of the support base 1. The rotating shaft 12 is rotatably connected to the side wall of the reinforcing column 16 via a bearing. This device can enhance the stability of the rotating shaft 12 during rotation, reduce the impact of vibration on the cabling process, ensure the smooth operation of each component, and extend the service life of the device. The positioning mechanism includes multiple positioning components 2, an adjustment component 3, and multiple tension components 4. The positioning component 2 includes a circular hole 21 opened on the side wall of the first turntable 13. Multiple first grooves 22 are equally spaced on the inner wall of the circular hole 21. Each of the multiple first grooves 22 is slidably connected to a moving column 23. A spring 24 is fixedly connected between the multiple moving columns 23 and the inner wall of the multiple first grooves 22. A spherical groove 25 is opened on the side wall of the multiple moving columns 23 that are close to each other. A limit ball 26 is rotatably connected in each of the multiple spherical grooves 25. The adjustment component 3 includes a second groove 31 opened on the side wall of the second turntable 15, and a rotating sleeve 32 is rotatably connected to the rotating shaft 12 via a bearing. A first bevel gear 33 is fixedly connected to the rotating sleeve 32 in the circumferential direction. The tension assembly 4 includes a strip groove 41 on the side wall of the second turntable 15. A threaded rod 42 is provided in the strip groove 41. The threaded rod 42 is rotatably connected to the inner wall of the second groove 31 through a bearing. A second bevel gear 43 is fixedly connected to the bottom end of the threaded rod 42. The second bevel gear 43 meshes with the first bevel gear 33. A nut 44 is threadedly connected to the threaded rod 42. Two guide rods 45 are fixedly connected to the upper surface of the nut 44. Both guide rods 45 are slidably connected to the circumferential side wall of the second turntable 15. Guide wheels 46 are fixedly connected to the top ends of the two guide rods 45. The rotating shaft 12, the first turntable 13, the connecting column 14, the second turntable 15, the second groove 31, and the rotating sleeve 32 are all concentrically arranged. Multiple round holes 21 and strip grooves 41 are equidistantly arranged around the rotating shaft 12. The number of positioning assemblies 2 and tension assemblies 4 are the same and they cooperate with each other. There are six positioning assemblies 2 and six tension assemblies 4.

[0021] The working principle of this utility model is as follows: When using the positioning device for cable making, the positioning component 2 will automatically adapt and adjust according to the diameter of the cable core. The cable core is passed through the round hole 21 of the first turntable 13. The cable core will push the limiting ball 26 to move outward. The limiting ball 26 drives the moving column 23 to slide in the first groove 22. The spring 24 is compressed. Under the elastic force of the spring 24, the limiting ball 26 tightly fits the surface of the cable core, realizing the positioning and guidance of the cable core. It can adapt to cable cores of different diameters. The number of positioning components 2 used is selected according to the number of cable cores. When using, the bundled cable cores are fixed on the side wall of the second turntable 15 (it is necessary to ensure that the cable core can be wound out normally). Then, the cable core is passed around the guide wheel 46 and through the round hole 21, so that the cable is made on the side of the first turntable 13 away from the second turntable 15. Then, the motor 11 is started, which drives the rotating shaft 12 to rotate. The rotating shaft 12 drives the first turntable 13, the connecting column 14 and the second turntable 15 to rotate synchronously. The wire core rotates with the turntable under the guidance of the positioning component 2, and the cabling process begins. When it is necessary to adjust the tension of the wire core, rotate the rotating sleeve 32. The rotating sleeve 32 drives the first bevel gear 33 to rotate. The first bevel gear 33 meshes with the second bevel gear 43, which drives the threaded rod 42 to rotate in the strip groove 41. Since the nut 44 is threadedly connected to the threaded rod 42, and under the limiting action of the guide rod 45, the nut 44 will move up and down along the threaded rod 42, which drives the guide rod 45 and the guide wheel 46 to move synchronously. The change in the position of the guide wheel 46 will change the degree of tension of the wire core, thereby realizing the adjustment of the tension of the wire core and keeping the wire core in a stable tension state during the cabling process. Throughout the cabling process, the limiting ball 26 rolls in contact with the wire core, reducing wear on the wire core. The reinforcing column 16 ensures the stability of the rotation of the shaft 12. The concentric arrangement of each component makes the rotation smoother and improves the quality of cabling.
