Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing technology, specifically to a multi-core robotic cable cabling device. Background Technology

[0002] In the field of robot cable manufacturing, the cabling process for multi-core cables has a crucial impact on product reliability and performance. Traditional cabling equipment mostly employs a fixed structural design. The core problem with this is the difficulty in dynamically adjusting the winding parameters of the cable cores (such as tension distribution and winding angle). This results in a singular and unadjustable stress state for each sub-wire within the cable, easily leading to localized stress concentration or relaxation, which in turn affects the cable's flexibility, fatigue resistance, and long-term service life. Furthermore, existing equipment has a low degree of functional modularity. When adding cable cores or adjusting cable specifications, it often requires replacing the entire set of tooling, which is cumbersome and costly, severely hindering improvements in production efficiency and product diversity.

[0003] To address the aforementioned technical bottlenecks, this invention proposes an innovative multi-core robotic cable winding device. This device introduces a rotatable pressure rod mechanism, utilizing the rotational motion of the pressure rod to actively apply controllable pressure, driving the cable cores to converge towards the rotation axis of the limiting frame. This achieves precise control over the winding force and angle of each sub-wire in the cable. This design breaks through the static constraints of traditional devices, resulting in a more uniform stress distribution within the cable, effectively reducing tension differences during winding, and significantly improving the structural stability and overall performance of the cable. It also expands the device's adaptability to cable cores of different specifications and material properties. Furthermore, this invention integrates an expandable external frame interface into the rotating frame assembly, supporting the rapid addition of additional twisting frames, enabling simultaneous processing of new cable cores without downtime modifications. This modular design significantly simplifies the production switching process for multi-specification cables, improves the flexibility and versatility of the equipment, and provides technical support for the efficient production of highly flexible, customized cables for industrial robots. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model proposes the following technical solution: A multi-core robot cable forming device includes a base and a cable core. A stranding device is provided on the base for stranding the formed cable into a cable. A twisting frame is installed on the rotating frame assembly for releasing the cable core. A limiting frame is provided on the base for limiting the cable core and controlling the tightness of the cable core during winding.

[0005] Furthermore, a side bracket is fixedly installed on the base, and a rotating frame assembly is rotatably installed on the side bracket. The rotating frame assembly is used to rotate for the cable winding process, and the rotating frame assembly can also be expanded to add multiple sets of cable cores.

[0006] Furthermore, the limiting frame includes a large fixed frame, a small fixed frame, and a connecting crossbar. The large fixed frame is fixedly connected to the base. A large turntable is rotatably installed inside the large fixed frame. The large turntable is provided with multiple sliding holes, which are used to limit the state of the cable core when it moves.

[0007] Furthermore, a small turntable is rotatably mounted inside the small fixed frame, and an adjusting gear ring is rotatably mounted on the small turntable. A drive gear is provided on the small turntable, and the drive gear meshes with the adjusting gear ring. The drive gear is controlled to rotate by a servo motor. Furthermore, an intermediate frame is rotatably mounted inside the small turntable, and multiple pressure rods are rotatably mounted on the intermediate frame.

[0008] Furthermore, the adjusting gear ring is provided with multiple protruding rods, and the pressure rod contacts the protruding rods on the adjusting gear ring.

[0009] Furthermore, the pressure bar includes an arc-shaped rod body and a pivot column. The pivot column is fixedly installed at one end of the arc-shaped rod body. The arc-shaped rod body is arc-shaped and has a twisting hole to limit the tightness of the cable core. The arc-shaped rod body has a sliding groove, and the protruding rod on the adjusting gear ring is restricted on the sliding groove.

[0010] Furthermore, the rotating frame assembly includes a central frame, an outer frame, and bolts. The central frame and the outer frame are fixedly connected by bolts. When multiple cable windings are not required, the outer frame can be separated from the central frame to reduce the operating costs of the device. The central frame is provided with seven mounting holes for mounting the torsion frame. Of the seven mounting holes on the central frame, one is located at the center of the central frame, and the other six are evenly arranged around this center position. The outer frame is provided with one mounting hole, and the outer frame is used to expand the mounting position of the torsion frame on the central frame.

[0011] Furthermore, the torsion frame is rotatably mounted on the rotating frame assembly. The torsion frame is driven to rotate by an external motor on the rotating frame assembly. The torsion frame includes a support shaft and a coil cylinder. One end of the support shaft is threaded with a large bolt, which is used to restrict the large bolt in the mounting hole in the rotating frame assembly.

[0012] Furthermore, the other end of the support shaft is provided with an installation frame, on which a wire outlet hole is movably installed. A small bolt is threaded onto one end of the wire outlet hole to restrict the wire outlet hole. A coil cylinder is provided on the outer wall of the wire outlet hole. The coil cylinder is slidably connected to the wire outlet hole. When the wire outlet hole is driven to rotate by an external drive device, the wire outlet hole will rotate together with the small bolt and the coil cylinder on the installation frame. A cable core is wound on the coil cylinder.

[0013] Furthermore, a rotating shaft is provided at the end of the support shaft mounting frame away from the large bolt, and the rotating shaft is used to restrict the passage of the cable core.

[0014] Furthermore, the surfaces of the rotating shaft, sliding hole, and twisting hole that contact the cable core are provided with a flexible wear-resistant layer.

[0015] The beneficial effects of this utility model compared with the prior art are: (1) This device can press the cable core towards the rotation axis of the limiting frame by rotating the pressure rod. This can not only change the winding force of each sub-wire in the cable, but also change the winding angle of the sub-wire in the cable. This can not only expand the applicable range of this device, but also reduce the tightness of the cable winding; (2) This device can add an external frame in the rotating frame assembly to install an additional twisting frame, so as to facilitate the addition of an additional twisting frame to this device, thereby adding different new cable cores for cable production, which improves the convenience and applicability of this device.

The large bolt 302 is used to restrict the large bolt 302 in the mounting hole in the rotating frame assembly 20. A mounting frame is provided at the other end of the support shaft 301. A wire outlet hole 304 is movably mounted on the mounting frame. One end of the wire outlet hole 304 is threaded... A small bolt 305 is installed to restrict the outlet hole 304.

When the outlet hole 304 is driven to rotate by an external drive device, the outlet hole 304 will rotate together with the small bolt 305 and the coil cylinder 303 on the mounting frame. A cable core 104 is wound on the coil cylinder 303. A rotating shaft 306 is provided at the end of the mounting frame of the support shaft 301 away from the large bolt 302. The rotating shaft 306 is used to restrict the passage of the cable core 104.

[0035] Example 4:

[0036] This embodiment further expands upon Embodiment 1 by modifying the limiting frame 40, such as... Figure 2 , Figure 3 and Figures 8 to 10As shown, the limiting frame 40 includes a large fixed frame 401, a small fixed frame 403, and a connecting crossbar 408. The large fixed frame 401 is fixedly connected to the base 101. A large turntable 402 is rotatably installed inside the large fixed frame 401. The large turntable 402 is provided with multiple sliding holes, which are used to limit the movement of the cable core 104. A small turntable 404 is rotatably installed inside the small fixed frame 403. An adjusting gear ring 405 is installed, and a drive gear 409 is provided on the small turntable 404. The drive gear 409 meshes with the adjusting gear ring 405 and is rotated by a servo motor. An intermediate frame 407 is rotatably installed inside the small turntable 404. Multiple pressure rods 406 are rotatably installed on the intermediate frame 407. Multiple protruding rods are provided on the adjusting gear ring 405, and the pressure rods 406 contact the protruding rods on the adjusting gear ring 405.

[0037] Example 5:

[0038] This embodiment further expands upon embodiment 4 by modifying the pressure bar 406, such as... Figures 9 to 11 As shown, the pressure rod 406 includes an arc-shaped rod body 4061 and a pivot column 4064. The pivot column 4064 is fixedly installed at one end of the arc-shaped rod body 4061. The arc-shaped rod body 4061 is arc-shaped and has a twisting hole 4063 to limit the tightness of the cable core 104. The arc-shaped rod body 4061 has a sliding groove 4062, and the protruding rod on the adjusting gear ring 405 is restricted in the sliding groove 4062. The surfaces of the rotating shaft 306, sliding hole, and twisting hole 4063 that contact the cable core 104 are provided with a flexible wear-resistant layer.

[0039] Working principle of this device: When this device is working, the coil tube 303 in the twisting frame 30 can be replaced. First, rotate the small bolt 305 on the outlet hole 304 to pull the outlet hole 304 and the small bolt 305 out of the mounting frame. This allows the used coil tube 303 to be removed from the mounting frame. Then, a new coil tube 303 can be placed in the mounting frame. Next, insert the outlet hole 304 into the coil tube 303. Finally, screw the small bolt 305 into the outlet hole 304 through the thread, thereby confining the outlet hole 304 in the mounting frame. In addition, it is necessary to connect the cable core 104 on the coil tube 303 with the remaining cable core 104 to facilitate subsequent work.

[0040] During operation, the stranding device 102 pulls the cable core 104 into the stranding device 102. At the same time, the rotating frame assembly 20 is driven to rotate externally, and the twisting frame 30 rotates on the rotating frame assembly 20. The coil drum 303 in the twisting frame 30 also needs to rotate slowly to release the cable core 104. The cable core 104 is wound into the stranding device 102 through the rotating shaft 306, sliding hole, and stranding hole 4063. During the winding process, the large turntable 402, small turntable 404, pressure rod 406, and intermediate frame 407 in the limiting frame 40 also rotate together with the rotating frame assembly 20, thereby assisting the cable winding process.

[0041] During the winding process, since the auxiliary wires or sub-wires used in different cables have different thicknesses, different pressures need to be applied to the cable cores 104 of different thicknesses during winding. At this time, the drive gear 409 is activated, which drives the adjusting gear ring 405 to rotate. The rotation of the adjusting gear ring 405 causes the pressure rod 406 to rotate through the protruding rod. The center of rotation of the pressure rod 406 is the rotating shaft column 4064. In this way, during the rotation of the pressure rod 406, it will twist the cable core 104 through the twisting hole 4063, thus pressing the cable core 104 closer to the rotation axis of the limiting frame 40. This not only changes the winding force of each sub-wire in the cable, but also changes the winding angle of the sub-wires in the cable.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
