Description

Technical Field

[0001] This invention relates to the technical field of wire harness processing, and more specifically to a wire harness stranding device. Background Technology

[0002] In the field of wire harness processing, stranding devices are key equipment used to strand multiple wires or cables together according to a certain pitch and direction. They are widely used in the production and manufacturing of products such as automotive wire harnesses, communication cables, and power cables.

[0003] Currently, traditional wire harness stranding devices still have the following defects in actual use: during the wire release, pulling and stranding process, dust, metal dust and other impurities are easily attached to the surface of the individual wires. These impurities will be directly retained on the surface of the wire harness during the stranding process. After stranding, the contact interface between individual wires is separated by impurities, which leads to a sharp increase in conductor resistance. The cable heats up severely after being energized, and may even cause a fire hazard. Summary of the Invention

[0004] The purpose of this invention is to provide a wire harness stranding device to overcome the above-mentioned defects in the prior art.

[0005] A wire harness stranding device includes a workbench, a fixed frame, a drive mechanism, a stranding mechanism, and a cleaning mechanism. The fixed frame is mounted on the workbench, and a turntable is rotatably connected to the fixed frame via a rotating shaft. The drive mechanism is mounted on the fixed frame and is used to drive the rotating shaft to rotate; The stranding mechanism is mounted on the fixed frame and turntable and is used to strand multiple wire bundles together. The cleaning mechanism includes a slide rod, a spring, a cleaning brush, a drive ring, and a drive rod. The slide rod is slidably connected to a fixed post and a rotating shaft on a turntable. A baffle is provided on the slide rod. The spring is sleeved on the slide rod and located between the baffle and the inner wall of the outer end of the slide rod. The cleaning brush is located at the outer end of the slide rod. A drive ring is sleeved on the rotating shaft on the fixed frame. A drive groove is provided along the circumference of the drive ring. The drive rod is located at the inner end of the slide rod and slidably connected to the slide groove on the rotating shaft. The drive rod abuts against the drive groove.

[0006] Furthermore, the drive mechanism includes a drive motor, a first gear, and a second gear. The drive motor is mounted on a mounting base on a fixed frame, and a first gear is mounted on the output shaft of the drive motor. The first gear meshes with the second gear on the rotating shaft.

[0007] Furthermore, the stranding mechanism includes a wire distributor, a limiting plate, and a lead tube. Several connecting seats are evenly distributed on the turntable. The wire distributor is detachably and rotatably mounted on the connecting seats. The limiting plate is located at the outer end of the fixed column. Limiting holes corresponding to the wire distributor are provided along the circumference of the limiting plate. One end of the fixed frame is provided with a lead tube for outputting the processed wire harness.

[0008] Furthermore, the cleaning brush has a circular structure and is connected to a slide rod via several connecting plates.

[0009] Furthermore, the drive groove has a peak-valley structure.

[0010] Furthermore, each connector is threaded with a limit bolt, and the distributor is sleeved on the limit bolt.

[0011] Furthermore, each of the limiting holes is provided with a limiting tube.

[0012] Furthermore, the mounting base includes a mounting plate and mounting posts, and the four corners of the mounting plate are respectively connected to the fixing frame through the mounting posts.

[0013] Furthermore, the fixing frame is fixed to the workbench by a number of fastening bolts.

[0014] The beneficial effects achieved by this invention are as follows: 1. In this application, while the turntable is rotating and twisting the wire, the drive rod of the cleaning mechanism slides along the peak-valley drive groove on the drive ring, generating axial reciprocating displacement, which drives the cleaning brush to perform high-frequency reciprocating brushing on the surface of the wire harness being twisted. This can remove impurities, dust and oil stains attached to the surface of the wire harness in a timely manner during the twisting process, and prevent impurities from being trapped inside the wire harness or remaining on the surface, thus significantly improving the quality of the finished wire harness.

[0015] 2. The reciprocating motion of the cleaning mechanism is powered by the rotation of the turntable itself. The rotation of the turntable is converted into the axial reciprocating motion of the slide rod through the peak-valley profile of the drive rod and the fixed drive ring. A stop plate with a spring is mounted on the slide rod, positioned between the stop plate and the inner wall of the outer end of the slide rod. When the drive rod is pushed outward by the peak of the drive groove, the spring is compressed; when the drive rod slides to the trough, the spring releases its energy and returns to its original position, pushing the slide rod back, resulting in continuous and uniform brushing action.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] like Figures 1 to 6 As shown, the present invention provides a wire harness stranding device, characterized in that: it includes a workbench 1, a fixed frame 2, a drive mechanism 5, a stranding mechanism 6, and a cleaning mechanism 7. The fixed frame 2 is fixed to the workbench 1 by a number of fastening bolts, which facilitates the assembly and disassembly of the fixed frame 2 on the workbench 1. A turntable 4 is rotatably connected to the fixed frame 2 by a rotating shaft 3. Furthermore, the drive mechanism 5 is mounted on the fixed frame 2 and is used to drive the rotating shaft 3 to rotate. The drive mechanism 5 includes a drive motor 51, a first gear 53, and a second gear 54. The drive motor 51 is mounted on a mounting base 52 on the fixed frame 2. The mounting base 52 includes a mounting plate 521 and a mounting post 522. The four corners of the mounting plate 521 are respectively connected to the fixed frame 2 through the mounting post 522. The first gear 53 is mounted on the output shaft of the drive motor 51, and the first gear 53 meshes with the second gear 54 on the rotating shaft 3. In addition, the stranding mechanism 6 is mounted on the fixed frame 2 and the turntable 4 and is used to strand multiple strands of wire together. The stranding mechanism 6 includes a wire splitter 63, a limiting plate 64 and a lead tube 65. Several connecting seats 62 are evenly distributed on the turntable 4. Each connecting seat 62 is threaded with a limiting bolt 621. The wire splitter 63 is sleeved on the limiting bolt 621. The limiting plate 64 is located at the outer end of the fixing post 61. A limiting hole 641 corresponding to the splitter plate 63 is provided along the circumference of the limiting plate 64. A limiting tube 642 is provided in each limiting hole 641. One end of the fixing frame 2 is provided with a lead tube 65 for outputting the processed wire harness. By setting the splitter plate 63, the limiting plate 64 and the lead tube 65, the twisting and orderly guidance of the multi-strand wire harness is realized. In addition, the cleaning mechanism 7 includes a slide rod 71, a spring 73, a cleaning brush 74, a drive ring 75, and a drive rod 76. The slide rod 71 is slidably connected to the fixed column 61 and the rotating shaft 3 on the turntable 4. A baffle 72 is provided on the slide rod 71. The spring 73 is sleeved on the slide rod 71 and is located between the baffle 72 and the inner wall of the outer end of the slide rod 71. The cleaning brush 74 is located at the outer end of the slide rod 71. The cleaning brush 74 has a circular structure and is connected to the slide rod 71 through several connecting plates 741, so that the cleaning brush 74 can clean the surfaces of multiple sub-lines at the same time. In addition, the fixed frame 2 is provided with a drive ring 75 sleeved on the rotating shaft 3, and a drive groove 751 is provided along the circumference of the drive ring 75. The drive groove 751 has a peak-valley structure. The drive rod 76 is located at the inner end of the slide rod 71 and is slidably connected to the slide groove 31 on the rotating shaft 3. The drive rod 76 abuts against the drive groove 751, so that the drive rod 76 can reciprocate between the peak and the valley when it rotates with the turntable 4. Detailed implementation methods and principles: When this device is in operation, the first step is to prepare for threading. The operator passes the multi-strand wire bundles to be twisted through the wire distribution disc 63 on the turntable 4 and through the corresponding limiting tube 642 on the corresponding limiting disc 64. Finally, the wires are passed out through the lead tube 65 at one end of the fixing frame 2 and initially fixed on the winding device at the outlet end of the lead tube 65. Next, start the stranded wire drive. The operator starts the drive motor 51. The output shaft of the drive motor 51 drives the gear 1 53 to rotate. The gear 1 53 transmits power to the rotating shaft 3 through meshing with the gear 2 54, so that the rotating shaft 3 drives the turntable 4 to start rotating at a constant speed around its axis. While the turntable 4 is rotating, the twisting action is performed automatically. Since one end of the multi-strand wire bundle is wound by the winding device at the outlet of the lead tube 65, and the other end rotates synchronously with the turntable 4, the multi-strand single wires are continuously wound and twisted together during the rotation process to form a tight wire bundle, which is continuously output from the lead tube 65. During the stranding process, the cleaning mechanism 7 works synchronously. When the turntable 4 rotates, the slide rod 71 fixedly connected to the turntable 4 and the slide rod 71 slidably connected to the rotating shaft 3 rotate together with the turntable 4. During the rotation, the drive rod 76 at the inner end of the slide rod 71 always keeps in contact with the drive groove 751 of the drive ring 75 on the fixed frame 2. Since the drive groove 751 has a peak-valley structure, the drive rod 76 will be constrained by the contour of the drive groove 751 when sliding along the drive groove 751, resulting in axial reciprocating displacement. When the drive rod 76 is pushed to the peak of the drive groove 751, the drive rod 76 pushes the slide rod 71 to slide outward along the slide groove 31 of the rotating shaft 3. The cleaning brush 74 at the outer end of the slide rod 71 then extends out and adheres to the surface of the wire harness. Meanwhile, the baffle 72 on the slide rod 71 compresses the spring 73. When the drive rod 76 slides towards the trough of the drive groove 751, the slide rod 71 is pushed back to its original position under the restoring force of the spring 73, and the cleaning brush 74 retracts accordingly. As the turntable 4 rotates continuously, the drive rod 76 continues to slide along the peak and valley contour of the drive groove 751, thereby driving the cleaning brush 74 to perform high-frequency reciprocating brushing on the surface of the twisted wire harness, brushing off the impurities and dust attached to the surface of the wire harness. After all the wire harnesses are twisted together, the drive motor 51 is turned off, and the turntable 4 stops rotating. The operator removes the twisted finished wire harness from the outlet of the lead tube 65, thus completing one work cycle. When it is necessary to replace the splitter 63 with a wire harness of different diameter, the operator only needs to unscrew the limit bolt 621 on the connector 62, remove the original splitter 63, replace it with the new splitter 63, and then tighten the limit bolt 621 to complete the quick replacement.
