Description

Technical Field

[0001] The invention relates to the technical field of wire harness twisting, in particular to a low-loss automobile wire harness twisting device. Background Art

[0002] The stranding process is a process in which the stranded single wires rotate at equal angular speeds around the stranding axis and the strands move forward at a uniform speed so that the individual copper wires are spirally wound together. Since there are a large number of copper wires in automobile manufacturing, the copper wires are easily scratched during the stranding process, which will directly lead to the loss of the roundness and smoothness of the copper wires. To solve this problem, the prior art will apply lubricants on the surface of the copper wires to solve this problem;

[0003] In order to avoid frequent shutdowns for lubrication, a device for wire harness twisting has been used. During the process of conveying wires to twist, lubricant is added to the wire wheel in real time, so that the conveying function of the wire wheel can be used to achieve the purpose of conveying and applying lubricating oil to the surface of the copper wire. However, this method is difficult to lubricate the copper wire comprehensively, and some areas on the copper wire that cannot be contacted by the wire wheel cannot be lubricated. At the same time, there is also a device in the prior art that solves the problem of incompleteness by directly applying lubricating oil to the copper wire. However, this device is still acceptable for single-strand wires, but when facing wire harnesses that have been stranded and are undergoing secondary twisting, the surface of the conveyed copper wire segment is irregular, and the problem of incomplete lubrication method is again reflected. Therefore, the existing wire harness twisting device has the defects of incomplete and incomplete solution to the problem of reducing wire harness losses, and needs to be improved in actual use.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention enables the oil cotton board to move with a zigzag path characteristic on a horizontal plane through the cooperation of structures such as a disc, a fixed axis and a limit frame. During the zigzag displacement of the oil cotton board, it will first contact the stranded wire harness, then remain relatively still with the wire harness, and move forward synchronously. After moving forward synchronously, it will then break away again until it contacts the wire harness next time. Since this method remains relatively still, it can first provide sufficient contact lubrication to the wire harness without affecting the advancement of the stranded wire. At the same time, this also solves the problem of difficulty in performing circumferential lubrication and difficulty in reducing losses in a comprehensive manner in the traditional method.

[0024] At the same time, compared with the direct coating method in some traditional measures, the oil cotton on the oil cotton board in this method is not easy to wear out, and the cotton wool is not easy to fall off on the wire harness, affecting the quality of the finished product, thereby further reducing the loss rate of the twisted wire harness.

[0025] Second, the present invention cooperates with the sleeve, gear, hinged rod and other structures to make the vibration block move back and forth during the displacement of the oil cotton board, and the reciprocating movement of the two symmetrically arranged vibration blocks can knock the wire harness to make the wire harness vibrate. In the process of twisting the wire harness that is not a single strand, the micro-vibration generated by the twisted wire can promote the lubricating oil attached to it to flow from the upper section to the lower section along the gully, so that the lubricating oil can be more immersed in the gully, making the lubrication more comprehensive, that is, the low-loss treatment measures are more comprehensive;

[0026] At the same time, during the stage when the stranded wire produces micro-vibration, there is a part when the oil-wool board remains relatively still and in contact with it. At this time, the micro-vibration of the stranded wire can further enhance the lubrication effect of the oil-wool board on the stranded wire bundle compared with ordinary contact, and the effect is better.

[0027] 3. The present invention cooperates with the structures of the slide seat 1, the slide seat 2 and the rack row to make the combing block move obliquely on the horizontal plane, so that the bottom of the gully of the stranded wire harness can be coated twice, avoiding the situation that the lubricating oil in the upper part of the gully flows slowly inward and the flow rate is small due to the inward curve of the gully area at the bottom of the wire harness cross section, which affects the comprehensive standard of reducing loss;

[0028] At the same time, the displacement of the combing block on the plane has an oblique feature, which can adapt to the advancement of the wire harness, that is, avoid unnecessary relative collision between the combing block and the wire harness to cause unnecessary losses, and can fit the grooves better and be more targeted.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] For example, see Figures 1 to 10 The present invention provides a low-loss automobile wire harness twisting device, comprising a bracket 1, to which a wire paralleling die 2, a twister 3 and a turntable 4 are fixedly connected, a lead-in device 5 is arranged in the twister 3, wire grooves 6 are provided on both sides of the twister 3, and six processing devices are fixedly connected to the inner wall of the twister 3.

[0042] The processing device includes a main body 7, both sides of which are provided with openings 35, the inner wall of the main body 7 is rotatably connected with a main shaft 8, two oil cotton plates 9 are arranged above the main shaft 8, and both sides of the two oil cotton plates 9 are provided with vibration blocks 10, a combing block 11 is arranged in the main body 7, and two groups of auxiliary components and matching components are also arranged in the processing device.

[0043] See also Figure 5 The two openings 35 are located on the same axis, and the cross-sectional sizes of the two openings 35 are slightly larger than the circular cross-sectional size formed by the two oil cotton boards 9. By limiting the position and size of the openings 35, the wire harness will not contact the edge of the opening 35 during the process of being twisted and transported, that is, no wear will occur on the connecting part of the structure.

[0044] The auxiliary components include a lubricating component, two groups of vibrating components, and a matching component. The two groups of vibrating components are both transmission-connected with the lubricating component, and the matching component is transmission-connected with the two groups of auxiliary components.

[0045] In this embodiment, the stranded, non-single wire harness is first passed through the turntable 4 and the wire twister 3, and then passed through the wire drawing mold 2 and connected to the traction device for stranding. Since each processing device contains a strand of stranded wire, in the process of stranding, in order to reduce the loss of the wire harness, the two groups of auxiliary components in the processing device can be started to operate, and the lubricating components in the two groups of auxiliary components are first driven to make the two oil cotton plates 9 displace with the characteristic of the zigzag path. Through the zigzag characteristic displacement of the oil cotton plates 9, when they come into contact with the wire harness, they will follow the synchronous displacement of the wire harness, that is, this process will make the oil cotton plates 9 and the wire harness remain relatively still. In this way, the capillary action can be used to apply the lubricating oil contained in the oil cotton plates 9 to the wire harness. In this process, the two groups of vibration components are driven synchronously to operate. The four vibration blocks 10 are caused to vibrate. Through the vibration of the four vibration blocks 10, the wiring harness can be knocked to make the wiring harness vibrate. This vibration can make the lubricating oil on the wiring harness penetrate deeper into the grooves, making the lubrication effect more comprehensive. In the process of the operation of the two sets of auxiliary components, the matching components will also be driven to operate. Through the operation of the matching components, the combing block 11 is displaced obliquely on the horizontal plane. Through the displacement of the combing block 11 on the horizontal plane, a second coating can be performed along the bottom groove formed by the strands to avoid the situation where the lubricating oil in the upper part of the groove flows less inward due to the inward curve of the groove area at the bottom of the wiring harness cross section. At the same time, this displacement has an oblique feature, which can follow the advancement of the wiring harness to avoid relative collision between the combing block 11 and the wiring harness to cause unnecessary losses, and is more targeted.

[0046] See also Figure 5 and Fig.10 The inner wall of the body 7 is fixedly connected with a motor 34, and the output end of the motor 34 is fixedly connected to the end of the main shaft 8. By starting the motor 34, the main shaft 8 can be conveniently driven to rotate continuously.

[0047] See also Figures 4 to 10 The lubricating component includes a disc 12, which is fixedly connected to the shaft wall of the main shaft 8. A continuous groove 13 is opened on the side wall of the disc 12. The continuous groove 13 includes a straight groove 14 and an inclined groove 15. The shaft arm of the main shaft 8 is fixedly connected with a fan-shaped plate 16. The inner wall of the main body 7 is slidably connected with a displacement frame 17. The side wall of the fan-shaped plate 16 fits with the inner wall of the displacement frame 17. The surface of the displacement frame 17 is fixedly connected with a limit frame 18. The inner wall of the limit frame 18 is slidably connected with a rod 19. The oil cotton board 9 is fixedly connected to the end of the rod 19 through a connector 36. The groove wall of the continuous groove 13 is slidably connected with a fixed shaft 40. The end of the fixed shaft 40 is fixedly connected to the bottom surface of the rod 19. The inner wall of the main body 7 is fixedly connected with a tank 20. The bottom of the tank 20 is connected to the oil cotton board 9 through a connecting component 39.

[0048] A rack row 21 is fixedly connected to the surface of the displacement frame 17 , and a limit rod 22 is slidably connected to the inner wall of the rack row 21 . The limit rod 22 is fixedly connected to the inner wall of the body 7 .

[0049] In this embodiment, the main shaft 8 is first rotated, and the disk 12 is driven to rotate by the rotation of the main shaft 8. The continuous groove 13 on the side wall of the disk 12 is rotated by the rotation of the disk 12. At this time, the fixed shaft 40 will slide along the groove wall of the continuous groove 13. At the same time, during the rotation of the main shaft 8, the fan-shaped plate 16 will be synchronously driven to rotate. The rotation of the fan-shaped plate 16 will push the displacement frame 17, so that the displacement frame 17 is horizontally reciprocated. At this time, the displacement frame 17 synchronously drives the limit frame 18 to reciprocate, and the displacement of the limit frame 18 will drive the rod 19 to reciprocate. , since the rod 19 is synchronously restricted by the fixed axis 40, based on the above, it can be realized that during the rotation of the main shaft 8, the limit frame 18 is pushed to drive the rod 19 to radially displace through the rotation of the sector plate 16. During this displacement process, the fixed axis 40 will slide along the groove wall of the straight groove 14 on the continuous groove 13. When the large arc edge of the sector plate 16 contacts the inner wall of the displacement frame 17 as the sector plate 16 rotates, the continued rotation of the sector plate 16 will no longer push the displacement frame 17 to displace. At the same time, the fixed axis 40 will be displaced to the intersection of the straight groove 14 and the inclined groove 15. At this time, the fixed axis 40 will be limited by the inclined groove 15 and move along the inclined groove 15. At this time, the fixed shaft 40 can be moved in the direction close to the displacement frame 17. When the fixed shaft 40 is separated from the inclined groove 15 and enters the straight groove 14 again, the large arc edge of the fan-shaped plate 16 will be separated from the inner wall of the displacement frame 17. At this time, it will push the displacement frame 17 to move in the reverse direction, causing the fixed shaft 40 to slide along the straight groove 14 again. In this way, the main shaft 8 can be continuously rotated, so that the rod 19 can be reciprocated on the horizontal plane with a back-and-forth feature. The displacement of component 19 synchronously drives connector 36 to be displaced, and the displacement of connector 36 can synchronously drive the oil cotton board 9 to be displaced in a U-shaped manner. During the U-shaped displacement of the oil cotton board 9, it will first contact the stranded wire harness, and then remain relatively still with the wire harness and move forward synchronously. After moving forward synchronously, it will then detach again until it contacts the wire harness next time. Since the lubricating oil in the tank 20 is transported to the oil cotton board 9 in real time through the connecting component 39, the lubricating oil on the oil cotton board 9 can be transferred to the surface of the wire harness while the oil cotton board 9 and the wire harness remain relatively still.

[0050] Compared with the traditional method, the U-shaped displacement performed synchronously by the two oil cotton plates 9 remains relatively still. Firstly, it can provide sufficient contact lubrication for the wire harness without affecting the advancement of the stranded wire. At the same time, it also solves the problem of difficulty in performing circumferential lubrication and difficulty in reducing losses in the traditional method.

[0051] At the same time, since the oil cotton board 9 and the wire harness remain relatively still during lubrication, compared with the direct coating method in some traditional measures, the oil cotton on the oil cotton board 9 is not easily worn out, and the cotton hair is not easy to fall off on the wire harness to affect the quality of the finished product, thereby further reducing the loss rate of the twisted wire harness.

[0052] Also, see Figure 5 The two groups of vibration components are symmetrically arranged, and the cross-sectional shape of the two oil cotton plates 9 is semicircular. Through the symmetrical arrangement of the two groups of vibration components, that is, the symmetrical arrangement of the two oil cotton plates 9, when the two oil cotton plates 9 are relatively still with the wiring harness and contact lubrication is performed, the cross-sectional shape of the two oil cotton plates 9 can be just spliced ​​into a circle. This setting can ensure the comprehensiveness of the lubrication of the wiring harness.

[0053] See also Figures 5 to 9 The vibration component includes a shaft body 23, which is fixedly connected to the inner wall of the body 7, and the shaft arm of the shaft body 23 is rotatably connected to a sleeve 24. The outer wall of the sleeve 24 is fixedly connected to a gear 25, and the teeth of the gear 25 mesh with the teeth of the rack row 21. The outer wall of the sleeve 24 is fixedly connected to a turntable 26, and an elliptical groove 27 is provided on the side of the turntable 26 away from the gear 25. The end of the shaft body 23 is fixedly connected to a rod seat 28, and the surface of the rod seat 28 is slidably connected to a push cylinder 29. The surface of the rod seat 28 is rotatably connected to the end of the sleeve 24, and the vibration block 10 is fixedly connected to the end of the push cylinder 29. The outer wall of the push cylinder 29 is hinged with a hinged rod 30, and the end of the hinged rod 30 is slidably connected to the groove wall of the elliptical groove 27 through a connector 2 37.

[0054] In this embodiment, during the displacement of the above-mentioned displacement frame 17, the rack row 21 is synchronously driven to be displaced. The reciprocating displacement of the rack row 21 will cause the gear 25 to rotate. The rotation of the gear 25 can cause the sleeve 24 to rotate on the outer wall of the shaft body 1 23. The rotation of the sleeve 24 can drive the turntable 26 to rotate. The rotation of the turntable 26 can cause the elliptical groove 27 thereon to perform a circular motion. Since one end of the hinged rod 30 is connected to the push cylinder 29, and the push cylinder 29 is restricted by the rod seat 28 and cannot rotate, the circular motion of the elliptical groove 27 can be used to make the connector 2 37 thereon reciprocate in the vertical direction. The reciprocating displacement of the connector 2 37 can be used to make the push cylinder 29 reciprocate along the rod wall of the rod seat 28 through the transmission of the hinged rod 30. In this way, the vibration block 10 can be reciprocated by the reciprocating displacement of the push cylinder 29.

[0055] By moving the two symmetrically arranged vibration blocks 10 back and forth, the wiring harness can be struck to cause it to vibrate. In the process of twisting non-single-strand wiring harnesses, the micro-vibration generated by the twisted wires can promote the lubricating oil attached to them to flow along the grooves from the top of the cross-section to the bottom of the cross-section, so that the lubricating oil can be more immersed in the grooves, making the lubrication more comprehensive, that is, the low-loss treatment measures are more comprehensive.

[0056] At the same time, it can be seen from the above that there is a part of the stage when the stranded wire produces micro-vibration when the oil cotton board 9 remains relatively still and in contact with it. At this time, the micro-vibration of the stranded wire can also make the oil cotton board 9 further enhance the lubrication effect applied to it compared with normal contact.

[0057] Embodiment 2, based on the above embodiment:

[0058] See also Figures 5 to 8 The mating parts include a slide 1 31 and a slide 2 32. The slide 2 32 is staggered with the slide 1 31. The inner walls of the slide 2 32 and the slide 1 31 are slidably connected with a combing shaft 33. The end of the combing shaft 33 is fixedly connected to the surface of the combing block 11. The slide 1 31 is fixedly connected to the ends of the two rack rows 21. Both ends of the slide 2 32 are fixedly connected to the inner wall of the body 7.

[0059] In this embodiment, during the displacement of the two rack rows 21, the slide 1 31 is synchronously driven to be displaced. The displacement of the slide 1 31 can push the combing shaft 33 on its inner wall to be displaced. Since the combing shaft 33 is restricted by the slide 2 32 at the same time, the combing shaft 33 will slide along the inner walls of the slide 1 31 and the slide 2 32 at the same time, that is, the combing shaft 33 will be displaced obliquely on the horizontal plane. The oblique displacement of the combing shaft 33 can make the combing block 11 displace obliquely on the horizontal plane, so that a secondary coating can be performed along the bottom of the gully of the stranded wire bundle, avoiding the situation that the lubricating oil in the upper part of the gully flows slowly inward and the amount is small due to the inward curve of the gully area at the bottom of the wire bundle cross section.

[0060] At the same time, this displacement has an oblique feature, which can adapt to the advancement of the wire harness, that is, avoid unnecessary relative collision between the combing block 11 and the wire harness to cause unnecessary losses, which is more targeted.

[0061] Also, see Figure 7 and Figure 8 Two stabilizing seats 38 are fixedly connected to the inner wall of the main body 7. The sizes of the two stabilizing seats 38 are respectively adapted to the sizes of the two rods 19. Through the setting of the two stabilizing seats 38, when the rod 19 performs a U-shaped displacement, it will be displaced in the stabilizing seats 38. Since there is no connection between the two, this is set to ensure the stability of the structure and reduce the damage rate of the equipment.

[0062] Working principle: When the low-loss automobile wire harness twisting device is used, the already stranded, non-single wire harness is first passed through the turntable 4 and the twister 3, and then passed through the paralleling mold 2 and connected to the traction device for twisting. Since each processing device contains a corresponding strand of stranded wire, in the process of twisting, in order to reduce the loss of the wire harness, the motor 34 in the processing device can be started to make the two oil cotton plates 9 first move in a zigzag path characteristic. Through the zigzag characteristic displacement of the two oil cotton plates 9, when they come into contact with the wire harness, they will follow the synchronous displacement of the wire harness. That is, this process will make the two oil cotton plates 9 and the wire harness remain relatively still. In this way, the capillary action can be used to apply the lubricating oil contained in the two oil cotton plates 9 to the wire harness. In this process, the four vibration blocks are driven synchronously. 10 generates vibration. Through the vibration of the four vibration blocks 10, the wiring harness can be knocked to make the wiring harness vibrate. This vibration can make the lubricating oil on the wiring harness penetrate deeper into the grooves, making the lubrication effect more comprehensive. In the process of the operation of the two sets of auxiliary components, the matching components will also be driven to operate. Through the operation of the matching components, the combing block 11 is displaced obliquely on the horizontal plane. Through the displacement of the combing block 11 on the horizontal plane, a second coating can be performed along the bottom groove formed by the strands to avoid the situation where the lubricating oil in the upper part of the groove flows less inward due to the inward curve of the groove area at the bottom of the wiring harness cross section. At the same time, this displacement has an oblique feature, which can avoid unnecessary losses caused by relative collision between the combing block 11 and the wiring harness as the wiring harness advances, and is more targeted.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
