Description

Technical Field

[0002] A cable is a wire used to transmit electric energy or signals, and its production process includes multiple processes. Among them, core threading is one of the key steps in cable manufacturing. Usually, a dedicated threading device is used to introduce the core into the protective sleeve.

[0003] After retrieval, the published document CN117854853A provides a core threading device for cable processing, which relates to the technical field of cable processing. It includes a workbench, and both sides of the upper surface of the workbench are movably installed with bottom plates. One side of the workbench is provided with a driving mechanism for controlling the movement of the bottom plates. The upper surface of the bottom plates is provided with a limiting mechanism. The middle part of the upper surface of the workbench is installed with a support frame, and the top of the support frame is installed with a mounting plate. Both sides of the upper surface of the mounting plate are movably installed with arc-shaped support blocks.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0056] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0057] An embodiment of the present invention provides a cable processing threading device, as Figures 1-6 shown, including:

[0058] A frame 1, which can fix the frame 1 to the ground by bolts;

[0059] A fixing component installed on the frame 1, which is used to fix one end of the threading port of the protective sleeve;

[0060] A threading component installed on the frame 1 and located on one side of the fixing component, which is used to thread the cable core into the protective sleeve;

[0061] The fixing component includes:

[0062] The mounting post 11 fixed to the frame 1 can be fixed by screws. A through hole is provided along the axis inside the mounting post 11.

[0063] Multiple fixing plates 21 arranged in the through hole are used to insert into the wire threading opening of the protective sleeve. The multiple fixing plates 21 are spaced apart around the axis of the mounting post 11. Preferably, an anti-slip portion, such as anti-slip lines or anti-slip teeth, is provided on the surface of the fixing plate 21 close to the inner wall of the protective sleeve.

[0064] A driving mechanism for driving the multiple fixing plates 21 to move synchronously in the radial direction of the mounting post 11. When the multiple fixing plates 21 move synchronously outward, they abut against the inner wall of the protective sleeve and expand one end of the wire threading opening, so as to fix the wire threading opening of the protective sleeve, and reduce the pressure and friction force of the wire threading opening on the cable core, facilitating wire threading.

[0065] Furthermore, the driving mechanism includes:

[0066] Multiple elastic telescopic rods circumferentially and spacedly installed inside the mounting post 11. The elastic telescopic rods are in one-to-one correspondence with the fixing plates 21 and are fixedly connected. The elastic telescopic rod includes a movable sleeve 9 and a pull rod 20. The movable sleeve 9 is slidably installed in the radial direction of the mounting post 11. The pull rod 20 penetrates into the movable sleeve 9 along the length direction of the movable sleeve 9. A tension spring 19 is fixedly connected between one end of the pull rod 20 located inside the movable sleeve 9 and the movable sleeve 9. The other end of the pull rod 20 is fixedly connected to one end of the fixing plate 21 close to the wire threading opening of the protective sleeve.

[0067] A power structure installed on the mounting post 11 for driving the movable sleeves 9 of all the elastic telescopic rods to move synchronously in the radial direction of the mounting post 11.

[0068] When the power structure drives all the movable sleeves 9 to move away from the fixing plate 21, the movable sleeve 9 pulls the pull rod 20 through the tension spring 19, and the pull rod 20 pulls the fixing plate 21 to abut against the inner wall of the protective sleeve, fixing the threading inlet of the protective sleeve. The greater the amount of movement of the movable sleeve 9 outward, the greater the fixing force of the fixing plate 21 on the protective sleeve, and the better the fixing effect. When the power structure drives all the movable sleeves 9 to move towards the fixing plate 21, the fixing force of the fixing plate 21 on the protective sleeve becomes smaller, releasing the protective sleeve.

[0069] Even further, the power structure includes:

[0070] A bevel gear ring 24 rotatably installed coaxially inside the mounting post 11, which can be rotatably installed through a bearing. The adjusting bevel gear is located on one side of the movable sleeve 9 and the two are connected by a planar thread.

[0071] An adjusting bevel gear rotatably installed on the mounting post 11 and meshing with the bevel gear ring 24, which can be rotatably installed through a bearing on the mounting shaft.

[0072] By rotating the adjusting bevel gear, the adjusting bevel gear drives the bevel gear ring 24 to rotate. The bevel gear ring 24 drives the movable sleeve 9 to move radially along the mounting column 11 through a planar thread connection.

[0073] In this embodiment, the wire threading assembly includes:

[0074] A gantry 6 fixed to the frame 1, which can be fixed by welding;

[0075] An upper rotating rod 30 and a lower rotating rod 31 rotatably mounted on the gantry 6, which can be rotatably mounted through bearings and are used to clamp the cable core and feed the cable core into the protective sleeve. Annular grooves can be provided on the roller walls of the upper rotating rod 30 and the lower rotating rod 31 to limit the cable core;

[0076] A first stepping motor 5 fixed to the gantry 6, which can be fixed by screws. The output shaft of the first stepping motor 5 is fixedly connected to one end of the lower rotating rod 31, which can be fixedly connected through a coupling;

[0077] During operation, the first stepping motor 5 is started. The first stepping motor 5 drives the lower rotating rod 31 to rotate, and the lower rotating rod 31 cooperates with the upper rotating rod 30 to feed the cable core into the protective sleeve.

[0078] In a specific implementation, both ends of the upper rotating rod 30 are respectively rotatably connected to mounting blocks 29 vertically and slidably mounted on both side walls of the gantry 6. The wire threading assembly further includes an adjusting mechanism for adjusting the acting force of the upper rotating rod 30 on the cable core. The adjusting mechanism includes:

[0079] A pressure rod 27 vertically fixed on the upper surface of each mounting block 29, which can be fixed by welding;

[0080] A pressure sleeve 7 sleeved on each pressure rod 27. A compression spring 28 is sleeved between the bottom end of the pressure rod 27 and the upper surface of the mounting block 29;

[0081] A pressure plate 8 fixedly connected between the tops of the two pressure sleeves 7. A threaded rod 26 is vertically penetrated through the pressure plate 8. The threaded rod 26 is threadedly connected to the pressure plate 8. The threaded rod 26 is rotatably connected to the gantry 6. A first bevel gear 32 is fixed to the bottom end of the threaded rod 26, and a second bevel gear 33 meshing with the first bevel gear 32 is fixed to the end of the lower rotating rod 31 away from the first stepping motor 5.

[0082] The first stepping motor 5 drives the lower rotating rod 31 to rotate, gradually feeding the cable core into the protective sleeve. The resistance of the protective sleeve to the cable core gradually increases. At the same time, the lower rotating rod 31 drives the second bevel gear 33 to rotate. The second bevel gear 33 drives the threaded rod 26 to rotate through the first bevel gear 32. The threaded rod 26 drives the pressing plate 8 to move downward gradually. The pressing plate 8 drives the pressing sleeve 7 to move downward gradually. The acting force of the pressing sleeve 7 on the mounting block 29 through the compression spring 28 gradually increases. Thus, the acting force of the upper rotating rod 30 on the cable core gradually increases. Therefore, the conveying force of the upper rotating rod 30 and the lower rotating rod 31 on the cable core gradually increases, improving the threading effect. After the threading is completed, the first stepping motor 5 rotates reversely to reset the pressing plate 8 upward.

[0083] Preferably, there is a connection structure between the power structure and the adjustment mechanism. The connection structure includes:

[0084] The rotating shaft 10 is rotatably installed on the gantry 6 and can be rotatably installed through bearings and bearing seats. One end of the rotating shaft 10 close to the mounting column 11 is provided with a worm section;

[0085] The third bevel gear 34 fixed to one end of the rotating shaft 10, and the third bevel gear 34 meshes with the first bevel gear 32;

[0086] The worm gear 22 fixed to the mounting shaft of the adjusting bevel gear, and the worm section meshes with the worm gear 22.

[0087] It should be explained that when the first bevel gear 32 rotates, it drives the third bevel gear 34 to rotate. The third bevel gear 34 drives the rotating shaft 10 to rotate. The worm section of the rotating shaft 10 rotates. The worm section drives the worm gear 22 to rotate. The worm gear 22 drives the adjusting bevel gear to rotate. The adjusting bevel gear drives the bevel gear ring 24 to rotate. When the bevel gear ring 24 drives all the movable sleeves 9 to move away from the fixed plate 21, the movable sleeve 9 pulls the pull rod 20 through the tension spring 19. The pull rod 20 pulls the fixed plate 21 to abut against the inner wall of the protective sleeve, fixing the threading port of the protective sleeve, and the fixing force on the protective sleeve gradually increases, improving the fixing effect on the protective sleeve.

[0088] In this embodiment, a mobile vehicle 18 is provided on one side of the frame 1. A heating component is installed on the mobile vehicle 18 for heating the protective sleeve to reduce the hardness of the protective sleeve, reduce the frictional resistance to the cable core. The softened protective sleeve is more likely to fit the irregular surface of the cable core through local deformation, reducing the risk of jamming. Of course, the heating temperature should be within a suitable range and cannot change the properties of the protective sleeve and the cable core. A moving mechanism is connected between the mobile vehicle 18 and the frame 1 for driving the mobile vehicle 18 to reciprocate relative to the frame 1, so as to be able to heat the protective sleeve reciprocally. Of course, the protective sleeve and the cable core in this application are of appropriate length and are not suitable for processing cables that are too long.

[0089] Further, the heating component includes:

[0090] The heating cylinder 12 is rotatably mounted on the mobile vehicle 18. Preferably, the heating cylinder 12 is coaxially arranged with the mounting column 11. Two mounting plates 15 can be fixedly spaced on the upper surface of the mobile vehicle 18, and the heating cylinder 12 is rotatably mounted between the two mounting plates 15 through bearings;

[0091] A plurality of electric heating sheets 16 are circumferentially and fixedly spaced on the inner side wall of the heating cylinder 12. The electric heating sheets 16 can be powered by a brush method. A temperature sensor can be installed on the inner side wall of the heating cylinder 12. The electric heating sheets 16 and the temperature sensor are electrically connected to an external temperature controller for controlling and adjusting the heating temperature;

[0092] The second stepping motor 17 fixed on the mobile vehicle 18 can be fixed by bolts. The second stepping motor 17 drives the heating cylinder 12 to rotate through a spur gear pair 14;

[0093] During operation, the protective sleeve is passed through the heating cylinder 12, and the second stepping motor 17 is started. The second stepping motor 17 drives the heating cylinder 12 to rotate through the gear pair, and the heating cylinder 12 drives the heating sheet to rotate to uniformly heat the protective sleeve by rotation.

[0094] Furthermore, an annular airbag 13 is fixed on the inner side wall of the heating cylinder 12, which can be fixed by glue. An air charging and discharging nozzle 25 communicating with the annular airbag 13 is provided on the outer side wall of the heating cylinder 12. The annular airbag 13 is inflated or deflated through the air charging and discharging nozzle 25, so that the inner side wall of the annular airbag 13 contacts the outer side wall of the protective sleeve. When the heating cylinder 12 rotates, the annular airbag 13 rotates relative to the protective sleeve, and the circumferential airbag rubs the protective sleeve like a hand, making the shape of the protective sleeve rounder, and preventing the cable core from getting stuck due to some parts being flat or severely deformed, which affects the passing of the cable core.

[0095] In a specific implementation, the moving mechanism includes:

[0096] A scissor mechanism 3 connected between the mobile vehicle 18 and the frame 1. The top hinge points at both ends of the scissor mechanism 3 are respectively hinged to the mobile vehicle 18 and the frame 1;

[0097] A power mechanism for driving the scissor mechanism 3 to expand and contract. The scissor mechanism 3 is driven to expand and contract through the power mechanism, so that the scissor mechanism 3 drives the mobile vehicle 18 to reciprocate relative to the frame 1.

[0098] Preferably, the power mechanism includes:

[0099] A first spur gear 35 fixed to one end of the lower rotating rod 31 away from the first stepping motor 5;

[0100] A second spur gear 36 rotatably mounted on the frame 1 and meshing with the first spur gear 35. The second spur gear 36 is larger than the first spur gear 35;

[0101] The connecting rod 2 has one end eccentrically hinged to the end face of the second spur gear 36, and the other end of the connecting rod 2 is hinged to the bottom hinge point of the scissor mechanism 3 near one end of the frame 1.

[0102] During operation, the first spur gear 35 rotates, the first spur gear 35 drives the second spur gear 36 to rotate, the second spur gear 36 drives the connecting rod 2 to reciprocate up and down, and the connecting rod 2 drives the scissor mechanism 3 to repeatedly expand and contract.

[0103] In summary, the present invention provides a cable processing threading device, and its working principle is as follows: The protective sleeve is passed through the heating cylinder 12 and then into the mounting post 11, and is sleeved on multiple fixing plates 21. The protective sleeve is initially fixed by the acting force of the tension spring 19 on the pull rod 20 and the fixing plate 21. The cable core is passed through the upper roller 30 and the lower roller 31 and into the threading port of the protective sleeve. The first stepping motor 5 is started to drive the lower roller 31 to rotate, gradually feeding the cable core into the protective sleeve. At the same time, the lower roller 31 drives the second bevel gear 33 to rotate, and the second bevel gear 33 drives the threaded rod 26 to rotate through the first bevel gear 32. The threaded rod 26 drives the pressing plate 8 to gradually move downward, and the pressing plate 8 drives the pressing sleeve 7 to gradually move downward. The acting force of the pressing sleeve 7 on the mounting block 29 through the compression spring 28 gradually increases, so that the acting force of the upper roller 30 on the cable core gradually increases, and thus the conveying force of the upper roller 30 and the lower roller 31 on the cable core gradually increases. When the first bevel gear 32 rotates, it drives the third bevel gear 34 to rotate, the third bevel gear 34 drives the rotating shaft 10 to rotate, the worm section of the rotating shaft 10 rotates, the worm section drives the worm wheel 22 to rotate, the worm wheel 22 drives the adjusting bevel gear to rotate, the adjusting bevel gear drives the bevel gear ring 24 to rotate. When all the movable sleeves 9 move away from the fixing plate 21, the movable sleeves 9 pull the pull rod 20 through the tension spring 19, and the pull rod 20 pulls the fixing plate 21 to abut against the inner wall of the protective sleeve, fixing the threading port of the protective sleeve, and the fixing acting force on the protective sleeve gradually increases. The second stepping motor 17 is started, and the second stepping motor 17 drives the heating cylinder 12 to rotate through the gear pair. The heating cylinder 12 drives the heating sheet to rotate, uniformly heating the protective sleeve by rotation. The first spur gear 35 rotates, the first spur gear 35 drives the second spur gear 36 to rotate, the second spur gear 36 drives the connecting rod 2 to reciprocate up and down, the connecting rod 2 drives the scissor mechanism 3 to repeatedly expand and contract, and the scissor mechanism 3 drives the moving vehicle 18 to reciprocate relative to the frame 1, heating the protective sleeve reciprocally.
