Description

A tooling and method for forming bundled cables Technical Field

[0001] This invention relates to the field of cable processing and manufacturing technology, specifically to a tooling and method for forming bundled cables. Background Technology

[0002] Bundled cables are cable products formed by combining multiple insulated wires or optical fibers together and binding and covering them through special processes. There are many equipment and methods for manufacturing these cables, but the basic principle is to twist multiple wires into a braided shape. Different cable thicknesses and lengths may require different cable forming methods. In some shorter cable laying applications, such as certain automotive cables, the cables used are not long, but multiple wires need to be combined and routed to the corresponding functional module areas for connection. Currently, the bundling of these cables is mostly done manually with the aid of simple tooling. For example, one end of each wire is fixed to the end of a corresponding support rod on a workbench and tightened with bolts, then the other ends are brought together and rotated, or even hand-braided. Some primitive manual operations are even done in a way similar to weaving straw rope. This method is not only inefficient but also difficult to control in terms of forming quality, heavily reliant on the operator's experience. In addition, after the wires are initially twisted together, they need to be wrapped with insulating materials such as insulating tape to shape the cable bundle. A common problem during this process is that, because the wires are not tightly twisted like steel cables, the cable bundle, which is already twisted into a spiral shape, tends to become increasingly loose and dispersed as the tape is spirally wound, resulting in a poor appearance and localized bulges in the cable bundle. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a cable bundling forming fixture and method to solve the problems of low cable forming efficiency, difficulty in controlling forming quality, and easy local fraying mentioned in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a cable bundling forming fixture, comprising a mounting part for mounting the ends of wires to be bundled, the mounting part comprising a first mounting part and a second mounting part arranged coaxially and oppositely, the second mounting part being able to rotate coaxially relative to the first mounting part to wind several wires into a twisted cable bundle, or to maintain the already twisted cable bundle within a set range of spiral winding tightness; further comprising a moving component connected to the two mounting parts to move the two mounting parts synchronously in a straight line while maintaining synchronous rotation; a belt pulley is provided on one side of the cable bundle, one end of the belt on the belt pulley being able to wrap around one end of the cable bundle, so that the cable bundle is spirally wound together by the belt while moving in a straight line and rotating on its own axis.

[0005] Furthermore, the mounting part includes an inner top component and an outer pressure component disposed on the mounting plate. The mounting plate is provided with a plurality of ring-shaped array of sockets, into which the ends of the power supply wires are inserted. The inner top component is located inside the outer pressure component, and the inner top component pushes the ends of the wires toward the outside of the mounting plate, while the outer pressure component squeezes the wires toward the inside of the mounting plate, so as to fix the ends of all the wires on the mounting plate.

[0006] Furthermore, the inner top component includes several sliders arranged in a ring at the center of the mounting plate. The sliders are slidably mounted in the mounting plate along the radial direction of the mounting plate. The opposing surfaces of the sliders are conical surfaces, and the small ends of the conical surfaces of the two mounting parts are arranged facing each other. It also includes a frustum-shaped slide, the small end of which faces the same direction as the small end of the conical surface. An adjusting stud is coaxially fixed to the slide, and the adjusting stud is screwed into the mounting plate in a threaded fit, so that the conical surface of the slide and the conical surfaces of all the sliders slide in synchronous and close contact, so that all the sliders move away from each other and push against their respective facing wire ends.

[0007] Furthermore, a guide block is fixed to the end of the slider. The guide block is slidably installed in the strip groove inside the mounting plate and abuts against a pre-tightening spring provided at one end of the strip groove.

[0008] Furthermore, a socket tube is coaxially fixed on the small end of the slide, and a compression spring is installed inside the socket tube. The compression spring slides in cooperation with a guide post that is axially slidably installed inside the socket tube, and the free end of the guide post abuts against the inner wall of the mounting plate.

[0009] Furthermore, the external pressure component includes a plurality of sliding pads in a ring array. A drive stud is rotatably mounted on the side of the sliding pad facing away from the slider. The drive stud is arranged radially along the mounting plate and threadedly passes through the outer side of the mounting plate before being coaxially fixed with a first cylindrical gear. All cylindrical gears mesh with the same planar gear so that all drive studs are simultaneously screwed into or out of the mounting plate.

[0010] The planar gear is fixed on the port of a knob cover, and an internal gear ring is coaxially fixed in the center of the knob cover. The internal gear ring meshes with a second cylindrical gear coaxially fixed on the adjusting stud through a speed-changing gear. When the adjusting stud is axially screwed into the mounting plate, the transmission stud is also radially screwed into the mounting plate.

[0011] Furthermore, the transmission gear is rotatably mounted on the end face of the mounting plate; the transmission stud has a T-bolt structure, and its nut is rotatably mounted inside the sliding bearing.

[0012] Furthermore, an operating disc is fixed to the end of the second cylindrical gear so that the adjusting stud can be rotated by rotating the operating disc; a fastening stud is also provided on the end face of the mounting disc, and the free end of the fastening stud abuts against the end face of the operating disc.

[0013] Furthermore, the moving component is one of the following two structural designs:

[0014] Structure 1: Includes two drive motors and two hydraulic rods. The main shaft of the drive motor is coaxially fixed to the mounting part through a connecting cylinder to drive it to rotate synchronously. The hydraulic rod is fixed to the mounting part to drive it to move linearly in the same direction.

[0015] Structure 2: The moving component is mounted on one of the mounting parts and includes a lead screw, a threaded support seat, and a motor. The motor is coaxially fixed to one end of the lead screw. The lead screw is threaded into the threaded support seat. One end of the lead screw extending out of the threaded support seat is coaxially fixed to the mounting part through a right-angle bent arm. The motor is horizontally slidably mounted on a guide rail, and the threaded support seat is fixed to one end of the guide rail near the mounting part.

[0016] Finally, based on the above tooling, the present invention also proposes a method for forming bundled cables. According to the cable processing requirements, several wires that have not yet been wound or have already been wound are selected and their ends are respectively installed on the mounting part. For the wires that have not yet been wound, the second mounting part needs to be rotated first so that the wires are wound to the required tightness to obtain a semi-finished cable bundle. Then, one end of the tape is pasted on the cable bundle. By moving the component, the two mounting parts are rotated on one side and moved to one side, so that the tape is spirally wound on the cable bundle.

[0017] This invention provides a cable bundle forming fixture and method, which has the following advantages: higher automation, higher forming efficiency, and more stable quality. Specifically, the mounting part automatically spirals and winds the cable bundle during rotation, forming a semi-finished cable bundle. Then, the mounting part, while rotating with the cable bundle, moves axially to spirally wind it with tape, forming a twisted binding structure. The entire process relies on corresponding automatic components and does not require strict manual operation, ensuring stable and controllable quality. Furthermore, another key advantage is that the two mounting parts can rotate to maintain a relative position. In this position, the cable bundle is always in a twisted state. Therefore, when it passes under the tape pulley due to its own weight and axial movement, the tape can evenly and stably wrap around the outside of the cable bundle, ensuring even and stable wrapping. This avoids the problem of loose and tangled wires caused by the spiral winding and squeezing of the tape at certain locations, resulting in a neat and aesthetically pleasing cable appearance. In addition, it can flexibly adjust the installation position of the ends of the wires to better obtain the desired cable, regardless of the wire thickness or the number of wires bundled together.

[0024] This specification will clearly and completely describe the technical solutions in the following embodiments based on the accompanying drawings. The embodiments described in this specification are only some embodiments of the present invention, not all embodiments. All other embodiments derived by those skilled in the art based on these embodiments without creative effort should fall within the protection scope of the present invention.

[0025] As shown in Figure 1, the cable bundling forming fixture in this embodiment mainly includes mounting parts 2 for mounting the ends of the wires 1 to be bundled. These two mounting parts 2 are a first mounting part and a second mounting part arranged coaxially and opposite to each other. Specifically, the second mounting part can rotate coaxially relative to the first mounting part to wind several wires 1 into a twisted cable bundle 3. If necessary, the second mounting part can also move linearly while rotating. Alternatively, during processing, the twisted cable bundle 3 can be kept within a set range of spiral winding tightness. This is because different wires 1 may have different twisting tightnesses when bundled. Wires that are too thin or too stiff only need to be wound until they do not easily come loose, which is different from common types such as bridge steel cables or some special cables. In addition, this embodiment also includes a moving component, which is directly or indirectly connected to the two mounting parts 2. Its purpose is to move the two mounting parts 2 synchronously in a straight line while maintaining synchronous rotation or relative rotation so that the wires 1 always have a set torque. This is to enable twisting or prevent the cable bundle 3 from loosening during movement, because it is necessary to wrap tape 4 on the outside. As shown in Figure 1, a tape wheel 5 is provided on one side of the cable bundle 3. One end of the tape 4 on the tape wheel 5 can be wrapped around one end of the cable bundle 3. This allows the cable bundle 3 to be spirally wrapped together with tape 4 while moving in a straight line and rotating on its own, thereby fixing the winding state of the cable bundle 3, or further securing the cable bundle 3 by wrapping and sticking tape 4. It also facilitates the cable bundle 3 to be bent at multiple positions without damaging the metal wires inside the wires 1.

[0026] As shown in Figures 2 and 3, the mounting part 2 in this embodiment includes an inner top component and an outer pressure component disposed on the mounting plate 6. The mounting plate 6 has several ring-shaped arrays of insertion holes into which the ends of the power cables 1 are inserted. Generally, the power cables 1 are distributed in a ring-shaped array within the corresponding insertion holes, similar to the processing of steel cables. Specifically, the inner top component is located inside the outer pressure component, and the inner top component pushes the ends of the power cables 1 outwards from the mounting plate 6, while the outer pressure component squeezes the power cables 1 inwards from the mounting plate 6. This clamps a section of the end of the power cable 1, fixing the ends of all the power cables 1 to the mounting plate 6. Most importantly, it allows for flexible adjustment to accommodate different thicknesses of the power cables 1 and to accommodate different cable integration processing applications, adjusting the installation spacing between the ends of a pair of power cables 1.

[0027] As shown in Figure 3, the inner top component in this embodiment includes several sliders 7 arranged in a ring at the center of the mounting plate 6. These sliders 7 are slidably mounted inside the mounting plate 6 along the radial direction of the mounting plate 6. The opposing surfaces of these sliders 7 are conical surfaces, and the small ends of the conical surfaces of the two mounting parts 2 are arranged facing each other. In addition, this embodiment also includes a frustum-shaped slide 8. The small end of this slide 8 faces the same direction as the small end of the conical surface, and an adjusting stud 9 is coaxially fixed on the slide 8. This adjusting stud 9 is screwed into the mounting plate 6 in a threaded fit, so that the conical surface of the slide 8 and the conical surfaces of all the sliders 7 slide in synchronous and close contact. When the adjusting stud 9 is screwed in, all the sliders 7 can be moved away from each other, thereby pushing the ends of the wires 1 that are facing each other.

[0028] As one of the specific implementation structures, a guide block 18 is fixed at the end of the slider 7. This guide block 18 is slidably installed in the strip groove in the mounting plate 6 and abuts against the pre-tightening spring 19 provided at one end of the strip groove to maintain the stability of the slider 7 and prevent it from moving accidentally.

[0029] In order to further maintain the stability of the overall structure during the adjustment process, a socket tube 20 is coaxially fixed on the small end of the slide table 8. A compression spring 21 is installed inside the socket tube 20. The compression spring 21 slides in cooperation with the guide post 22 which is axially slidably installed inside the socket tube 20. The free end of the guide post 22 abuts against the inner wall of the mounting plate 6, so that the slide table 8 slides more stably in the axial direction.

[0030] Referring again to Figure 3, the external pressure component in this embodiment includes a plurality of sliding plates 11 arranged in a ring. A drive stud 12 is rotatably mounted on the side of these sliding plates 11 facing away from the slider 7. All drive studs 12 are arranged radially along the mounting plate 6 and are threaded through the outside of the mounting plate 6. A first cylindrical gear 13 is also specifically fixed coaxially thereon. The cylindrical gear is a special gear similar to a spline with a very large tooth thickness. All cylindrical gears mesh with the same planar gear 14. Through this structural design, all drive studs 12 can be screwed into or out of the mounting plate 6 synchronously, and the meshing state is always maintained during the axial movement of the drive studs 12.

[0031] More specifically, as shown in Figure 3, the planar gear 14 is fixed to the port of a knob cover 15. An internal gear ring 16 is coaxially fixed to the center of the knob cover 15. The internal gear ring 16 meshes with a second cylindrical gear 10 coaxially fixed to the adjusting stud 9 via a speed-changing gear 17. This is also to ensure that the adjusting stud 9 maintains an indirect transmission relationship with the internal gear ring 16 during axial movement. That is, when the adjusting stud 9 is axially screwed into the mounting plate 6, the transmission stud 12 is also radially screwed into the mounting plate 6, thereby clamping and fixing a section of the corresponding wire end. In practice, the speed-changing gear 17 can be rotatably mounted on the end face of the mounting plate 6, and the aforementioned transmission stud 12 can be a T-bolt structure with a round nut, rotatably mounted within the sliding plate 11.

[0032] To drive the adjusting stud 9 to rotate, as shown in Figure 3, an operating disc 23 is fixed to the end of the second cylindrical gear 10. Rotating the operating disc 23 causes the adjusting stud 9 to rotate. A fastening stud 24 is also provided on the end face of the mounting disc 6. When the free end of the fastening stud 24 abuts against the end face of the operating disc 23, the adjusting stud 9 is axially fixed, that is, the position of the slide 8 is fixed. All the sliders 7 and all the sliding plates 11 maintain a constant position, achieving simultaneous fixation of these clamping elements at one time, which is very ingenious.

[0033] In terms of specific manufacturing, the moving component in this embodiment is one of the following two structural designs, both of which can realize the processing of cable bundle 3. As one of the structures, it mainly relies on the automatic function of the components to achieve this directly, that is, it includes two drive motors and two hydraulic rods. The main shaft of the drive motor is coaxially fixed to the mounting part 2 through a connecting cylinder, which can drive the second mounting part to rotate synchronously. The hydraulic rods are fixed to the mounting part 2, which can simply and directly drive the second mounting part to move linearly in the same direction.

[0034] In addition, as shown in Figure 5, as another implementation structure, this moving component is set on one of the mounting parts 2, which can be a second mounting part. Specifically, it includes a lead screw 26, a threaded support seat 27, and a motor 25. The motor 25 is coaxially fixed to one end of the lead screw 26, driving it to rotate. The lead screw 26 is threaded into the threaded support seat 27, which is fixedly installed. The end of the lead screw 26 that extends out of the threaded support seat 27 is fixedly installed coaxially with the mounting part 2 through a right-angle bent arm 28. When the main shaft rotates, one end of the wire 1 begins to twist in a spiral shape. If both mounting parts 2 are coaxially fixed to the main shaft through a bent arm 28, the cable bundle 3 rotates as a whole, realizing the spiral winding of the tape 4. In the above structure, due to the transmission of the threaded pair, the main shaft and the motor 25 will move axially. Therefore, the motor 25 is horizontally slidably mounted on a guide rail 29 for smooth sliding. The threaded support 27 is fixed to one end of the guide rail 29 near the mounting part 2. Usually, some cables inside the car that need to be bundled are not very long. Therefore, the screw 26 is used to realize rotation and axial movement. Its length is sufficient, and the structure is simple, reliable, easy to manufacture and use.

[0035] Finally, as a specific embodiment, a method for forming bundled cables is introduced. During the forming process, several unwound or already wrapped wires 1 are selected and their ends are respectively installed on the mounting part 2 according to the cable processing requirements. For the unwound wires 1, the second mounting part needs to be rotated first to make the wires 1 wound to the required tightness, resulting in a semi-finished cable bundle 3. Then, one end of the tape 4 is pasted onto the cable bundle 3. By moving the assembly, the two mounting parts 2 rotate on their own axis and move to one side, automatically causing the tape 4 to spirally wrap around the cable bundle 3. This forming method can also avoid the accidental situation where the local wires 1 of the cable bundle 3 separate further and become loose and scattered due to the spiral compression and winding of the tape 4 when wrapping the tape 4 on the outer layer of the cable bundle 3.

[0036] It should be clarified here that, in this specification, terms such as "first" and "second" are merely used to distinguish one feature from another, and do not imply any inherent relationship or order between these technical features. The terms "comprising" and "including" mean that something contains one or more technical means or features, specifically referring to other existing or non-existent technical features not listed above. The descriptions in the above embodiments are merely representative examples for the purposes of this invention and are not the only limiting features. Those skilled in the art should understand that, without departing from the technical content described in all claims of this application, simple substitutions and modifications can be made to create different or equivalent specific embodiments and application scenarios. However, regardless of these adaptive changes, all such embodiments must fall within the protection scope of this invention.
