Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and in particular to a cable conductor processing and straightening device. Background Technology

[0002] A cable straightening device is a device used to straighten bent cables during secondary wiring. In recent years, with the development of power grids, substation renovation and upgrading projects have also increased. During construction, the secondary wiring process takes up a lot of construction time, and the straightening of the cable core is crucial in the wiring process.

[0003] Currently, the traditional method of straightening cables generally involves construction workers manually restoring the deformation of the cable core using tools. This method is not only time-consuming and labor-intensive, but also has poor straightening effect. Therefore, a cable straightening device is proposed to optimize and solve the above problems.

[0004] A novel cable conductor straightening device disclosed in CN222607851U includes a cable straightening device body. A movable block is movably mounted on the front of the cable straightening device body, and a rotating wheel is movably mounted on the surface of the movable block. A fixed block is fixedly mounted on the right side of the cable straightening device body, and a feed port is opened at the top of the fixed block. By pressing the cable clamping plate to the bottom, a tension spring pulls a rotating brush inward and clamps it on both sides of the cable. When the cable moves, it drives the rotating brush to rotate. The rotating brush picks up dry powder flowing from the discharge port, reducing friction and preventing adhesion. The height of the movable block is adjusted by a hydraulic rod, and the cable squeezes the rotating wheel outward. A first spring causes the rotating wheel to wrap around the cable, making it easier for the cable to fit the cable straightening device body and facilitating the straightening of cables of different sizes.

[0005] While the aforementioned patent achieves the goal of rotating a brush when the cable moves, causing it to pick up dry powder from the discharge port, reducing friction and preventing sticking, and adjusting the height of the moving block via a hydraulic rod, and separating the cable by squeezing the rotating wheel outwards, with a first spring causing the rotating wheel to wrap around the cable for better fit with the cable straightening device body and easy straightening of cables of different sizes, the device's straightening wheel can only apply vertical pressure. It cannot eliminate axial torsion or horizontal bending deformation of the cable, thus requiring multiple straightening operations, leading to increased energy consumption. Furthermore, the device lacks a lifting module, making it difficult for the fixed-height worktable to form gradient pressure with other modules, affecting collaborative work. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] The purpose of this invention is to provide a cable conductor processing and straightening device, which solves the problems mentioned in the background art. The straightening wheel of the device can only apply pressure in the vertical direction, which cannot eliminate the axial torsion or horizontal lateral bending deformation of the cable. As a result, the cable needs to be straightened multiple times, which increases energy consumption. In addition, the device is not equipped with a lifting module, and the fixed height worktable is difficult to form gradient pressure with other modules, which affects the collaborative work.

The positioning roller device plays a role in the initial positioning of the cable conductor processing.

[0014] As a further embodiment of this utility model, multiple sets of adjusting bolts are threadedly connected to one side of the vertical roller device, the horizontal roller device, the positioning roller device, and the driving roller device. The alignment center positions of the vertical roller device, the horizontal roller device, the positioning roller device, and the driving roller device are on the same horizontal line. The driving roller device plays a role in moving the position of the cable conductor.

[0015] As a further embodiment of this utility model, four sets of telescopic rods are symmetrically arranged at the bottom of the workbench, and a support frame is fixedly connected to the bottom of the four sets of telescopic rods. The telescopic rods serve to support the workbench.

[0017] (III) Beneficial Effects

[0018] This utility model provides a cable conductor processing and straightening device, which has the following beneficial effects:

[0019] 1. This cable conductor processing and straightening device, through the setup of a microcontroller, a vision inspection unit, a multi-segment mechanism, and a multi-directional mechanism, allows the cable conductor to pass through a positioning roller device during processing and straightening. The cable conductor passes through a vertical roller device and then a horizontal roller device in sequence to correct the vertical and horizontal bending of the cable. The vision inspection unit collects the conductor surface curvature data using a linear CCD camera and sends a signal to the microcontroller. The microcontroller calculates the swing angle of the straightening head and then controls a servo motor A to drive the straightening head to rotate at a micro-angle. The spiral guide groove on the inner side of the straightening head guides the cable rotation, eliminating the combined bending of axial and radial directions. This multi-method coordinated straightening achieves three-dimensional straightening, while also improving the accuracy and efficiency of conductor straightening and avoiding the inefficiency caused by multiple straightening operations.

[0020] 2. This cable conductor processing and straightening device, through the setting of a dual-head servo motor and a lifting mechanism, starts the dual-head servo motor before processing and straightening. The dual-head servo motor synchronously drives the worm gears on both sides to rotate, and the worm gears drive the worm wheel and lead screw to rotate. The lead screw rotates and lifts in the sleeve rod, thereby realizing the height adjustment of the worktable. Thus, the lifting mechanism can electrically adjust the height of the worktable, supporting synchronous adjustment with the height of the equipment in the preceding and following processes, reducing the bending stress of the cable transition section, improving continuous production efficiency. At the same time, the operator can adjust the worktable to the optimal operating height with one click, avoiding bending over or tiptoeing to work, and reducing labor intensity.
