Description

Technical Field

[0001] This invention belongs to the technical field of cable manufacturing equipment, and particularly relates to a cable processing and threading device. Background Technology

[0002] A cable is a wire used to transmit electrical energy or signals, and its production process involves multiple steps. Among these, threading the cable core is one of the key steps in cable manufacturing, typically using specialized threading equipment to guide the cable core into the protective sheath.

[0003] A search revealed that document CN117854853A discloses a cable core threading device for cable processing, relating to the field of cable processing technology. The device includes a workbench with base plates movably mounted on both sides of its upper surface. A drive mechanism for controlling the movement of the base plates is provided on one side of the workbench. A limit mechanism is provided on the upper surface of the base plates. A support frame is mounted in the middle of the upper surface of the workbench, and an mounting plate is mounted on the top of the support frame. Arc-shaped support blocks are movably mounted on both sides of the upper surface of the mounting plate.

[0004] The aforementioned prior art clearly describes that the threaded rod is rotated by turning a knob. Under the meshing action of the threaded rod and the threaded hole, the arc-shaped clamp at one end can move back and forth during the rotation, so that the two arc-shaped clamps can clamp and fix the sheath, which is more conducive to the cable core threading work. However, by using the method of clamping and fixing the sheath from the outside, the clamping force on the sheath will increase the friction between the sheath and the cable core, which may cause the cable core to get stuck during threading and affect the threading efficiency.

[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 art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0056] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0057] This invention provides a cable processing and threading device, such as... Figures 1-6 As shown, it includes:

[0058] Frame 1 can be fixed to the ground with bolts;

[0059] The mounting assembly installed on the frame 1 is used to secure one end of the cable threading port of the protective sleeve.

[0060] The cable threading assembly, installed on the rack 1 and located on one side of the fixed assembly, is used to thread the cable core into the protective sleeve;

[0061] The fixing component includes:

[0062] The mounting post 11, which is fixed to the frame 1, can be fixed by screws. The mounting post 11 has a through hole along its axis.

[0063] Multiple fixing plates 21 are provided in the through hole for insertion into the wire hole of the protective sleeve. The multiple fixing plates 21 are distributed at intervals around the axis of the mounting post 11. Preferably, the surface of the fixing plate 21 near the inner wall of the protective sleeve is provided with anti-slip parts, such as anti-slip patterns or anti-slip teeth.

[0064] The drive mechanism is used to drive multiple fixing plates 21 to move synchronously along the mounting column 11 radially. When the multiple fixing plates 21 move outward synchronously, they press against the inner wall of the protective sleeve and expand one end of the wire threading port, which can fix the wire threading port of the protective sleeve and reduce the pressure and friction of the wire threading port on the cable core, making it convenient to thread the wire.

[0065] Furthermore, the drive mechanism includes:

[0066] Multiple elastic telescopic rods are installed circumferentially within the mounting column 11. Each elastic telescopic rod corresponds to and is fixedly connected to the fixing plate 21. Each elastic telescopic rod includes a movable sleeve 9 and a pull rod 20. The movable sleeve 9 is slidably installed radially along the mounting column 11. The pull rod 20 passes through the movable sleeve 9 along its length. One end of the pull rod 20 located inside the movable sleeve 9 is fixedly connected to the movable sleeve 9 with a tension spring 19. The other end of the pull rod 20 is fixedly connected to the end of the fixing plate 21 near the wire insertion port of the protective sleeve.

[0067] The power structure installed on the mounting column 11 is used to drive the movable sleeves 9 of all elastic telescopic rods to move synchronously along the radial direction of the mounting column 11.

[0068] When the power structure drives all the movable sleeves 9 to move away from the fixed plate 21, the movable sleeves 9 pull the pull rod 20 through the tension spring 19. The pull rod 20 pulls the fixed plate 21 to press against the inner wall of the protective sleeve, thus fixing the entrance of the protective sleeve. The greater the amount of movement of the movable sleeves 9 to the outside, the greater the fixing force of the fixed plate 21 on the protective sleeve, and the better the fixing effect. When the power structure drives all the movable sleeves 9 to move closer to the fixed plate 21, the fixing force of the fixed plate 21 on the protective sleeve decreases, and the protective sleeve is released.

[0069] Furthermore, the power structure includes:

[0070] A beveled ring 24, which is rotatably mounted on the mounting column 11 along the same axis, can be rotatably mounted via a bearing. The beveled ring 24 is located on one side of the movable sleeve 9 and the two are connected by a planar thread.

[0071] The adjusting bevel gear 23, which is rotatably mounted on the mounting column 11 and meshes with the bevel gear ring 24, can be rotatably mounted via the mounting shaft bearing.

[0072] By rotating the adjusting bevel gear 23, the adjusting bevel gear 23 drives the bevel gear ring 24 to rotate, and the bevel gear ring 24 drives the movable sleeve 9 to move radially along the mounting column 11 through the planar thread connection.

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

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

[0075] The upper rotating roller 30 and the lower rotating roller 31, which are rotatably mounted on the gantry frame 6, can be rotatably mounted via bearings. They are used to clamp the cable core and feed the cable core into the protective sleeve. Annular grooves can be opened on the roller walls of the upper rotating roller 30 and the lower rotating roller 31 to limit the movement of the cable core.

[0076] The first stepper motor 5, which is fixed on the gantry frame 6, can be fixed by screws. The output shaft of the first stepper motor 5 is fixedly connected to one end of the lower rotating roller 31, which can be fixedly connected by a coupling.

[0077] During operation, the first stepper motor 5 is started, which drives the lower rotating roller 31 to rotate. The lower rotating roller 31 works in conjunction with the upper rotating roller 30 to feed the cable core into the protective sleeve.

[0078] In a specific implementation, the two ends of the upper rotating roller 30 are rotatably connected to the mounting blocks 29 vertically slidably installed on both sides of the portal frame 6. The threading assembly also includes an adjustment mechanism for adjusting the force exerted by the upper rotating roller 30 on the cable core. The adjustment mechanism includes:

[0079] The pressure bar 27, which is vertically fixed on the upper surface of each mounting block 29, can be fixed by welding.

[0080] A pressure sleeve 7 is fitted onto each pressure rod 27, and a compression spring 28 is fitted onto the pressure rod 27 between the bottom end of the pressure sleeve 7 and the upper surface of the mounting block 29.

[0081] A pressure plate 8 is fixedly connected between the tops of two pressure sleeves 7. A threaded rod 26 is vertically inserted through the pressure plate 8. The threaded rod 26 is threadedly connected to the pressure plate 8 and rotatably connected to the gantry frame 6. A first bevel gear 32 is fixed at the bottom end of the threaded rod 26. A second bevel gear 33 that meshes with the first bevel gear 32 is fixed at the end of the lower rotating roller 31 away from the first stepper motor 5.

[0082] The first stepper motor 5 drives the lower rotating roller 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 roller 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 pressure plate 8 to move downward gradually. The pressure plate 8 drives the pressure sleeve 7 to move downward gradually. The pressure sleeve 7 gradually increases the force on the mounting block 29 through the compression spring 28. As a result, the force of the upper rotating roller 30 on the cable core gradually increases. Thus, the conveying force of the upper rotating roller 30 and the lower rotating roller 31 on the cable core gradually increases, improving the threading effect. After threading is completed, the first stepper motor 5 reverses, causing the pressure plate 8 to move upward and reset.

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

[0084] The rotating shaft 10 is rotatably mounted on the portal frame 6 and can be rotatably mounted via bearings and bearing seats. The end of the rotating shaft 10 near the mounting column 11 is provided with a worm gear section.

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

[0086] A worm gear 22 is fixed on the mounting shaft of the adjusting bevel gear 23, and the worm section meshes with the worm gear 22.

[0087] It needs to 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, which drives the worm wheel 22 to rotate. The worm wheel 22 drives the adjusting bevel gear 23 to rotate, which drives the bevel ring 24 to rotate. When the bevel ring 24 drives all the movable sleeves 9 to move away from the fixed plate 21, the movable sleeves 9 pull the pull rod 20 through the tension spring 19. The pull rod 20 pulls the fixed plate 21 to press against the inner wall of the protective sleeve, fixing the entrance of the protective sleeve. The fixing force on the protective sleeve gradually increases, improving the fixing effect of the protective sleeve.

[0088] In this embodiment, a moving carriage 18 is provided on one side of the frame 1. A heating component is installed on the moving carriage 18 to heat the protective sleeve, thereby reducing the hardness of the protective sleeve and decreasing the frictional resistance to the cable core. The softened protective sleeve is more likely to conform to the irregular surface of the cable core through local deformation, reducing the risk of jamming. Of course, the heating temperature must be within a suitable range and must not change the performance of the protective sleeve and the cable core. A moving mechanism is connected between the moving carriage 18 and the frame 1 to drive the moving carriage 18 to move back and forth relative to the frame 1, thereby enabling reciprocating heating of the protective sleeve. Of course, the protective sleeve and cable core in this application are of appropriate length and are not suitable for processing cables that are too long.

[0089] Furthermore, the heating assembly 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 fixed at intervals on the upper surface of the mobile vehicle 18. The heating cylinder 12 is rotatably mounted between the two mounting plates 15 through bearings.

[0091] Multiple heating elements 16 are fixed circumferentially on the inner wall of the heating cylinder 12. The heating elements 16 can be powered by brushes. A temperature sensor can be installed on the inner wall of the heating cylinder 12. The heating elements 16 and the temperature sensor are electrically connected to an external temperature controller for controlling and adjusting the heating temperature.

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

[0093] During operation, the protective sleeve is passed through the heating cylinder 12, and the second stepper motor 17 is started. The second stepper motor 17 drives the heating cylinder 12 to rotate through the gear pair, and the heating cylinder 12 drives the heating plate to rotate, so as to rotate and heat the protective sleeve evenly.

[0094] Furthermore, an annular airbag 13 is fixed on the inner wall of the heating cylinder 12, which can be fixed with glue. An inflation / deflation nozzle 25 communicating with the annular airbag 13 is provided on the outer wall of the heating cylinder 12. The annular airbag 13 is inflated or deflated through the inflation / deflation nozzle 25, so that the inner wall of the annular airbag 13 contacts the outer wall of the protective sleeve. When the heating cylinder 12 rotates, the annular airbag 13 rotates relative to the protective sleeve. The annular airbag rubs the protective sleeve like a hand, making the shape of the protective sleeve more rounded. This prevents the cable core from getting stuck due to some parts being flat or severely deformed, thus affecting the cable core's passage.

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

[0096] A scissor mechanism 3 is connected between the mobile vehicle 18 and the frame 1, and 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] The power mechanism is used to drive the extension and retraction of the scissor lift mechanism 3. The scissor lift mechanism 3 is driven to extend and retract, thereby driving the moving vehicle 18 to move back and forth relative to the frame 1.

[0098] Preferably, the power mechanism includes:

[0099] The first spur gear 35 is fixed to the end of the lower rotating roller 31 away from the first stepper motor 5;

[0100] A second spur gear 36 is rotatably mounted on the frame 1 and meshes with the first spur gear 35, the second spur gear 36 being larger than the first spur gear 35;

[0101] One end of the connecting rod 2 is 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 the end of the frame 1.

[0102] During operation, the first spur gear 35 rotates, which drives the second spur gear 36 to rotate. The second spur gear 36 drives the connecting rod 2 to move up and down reciprocally, and the connecting rod 2 drives the scissor mechanism 3 to extend and retract repeatedly.

[0103] In summary, this invention provides a cable processing and threading device. Its working principle is as follows: a protective sleeve is passed through a heating cylinder 12 and then through an mounting post 11, and fitted onto multiple fixing plates 21. The protective sleeve is initially fixed by the force exerted by the tension spring 19 on the pull rod 20 and the fixing plates 21. The cable core is passed through the upper rotating roller 30 and the lower rotating roller 31 and inserted into the threading opening of the protective sleeve. The first stepper motor 5 is started, driving the lower rotating roller 31 to rotate and gradually feed the cable core into the protective sleeve. Simultaneously, the lower rotating roller 31 drives the second bevel gear 33 to rotate. The second bevel gear 33, through the first bevel gear 32, drives the threaded rod 26 to rotate. The threaded rod 26 drives the pressure plate 8 to move gradually downwards. The pressure plate 8 drives the pressure sleeve 7 to move gradually downwards. The pressure sleeve 7, through the compression spring 28, gradually increases the force exerted by the compression spring 28 on the mounting block 29, thereby gradually increasing the force exerted by the upper rotating roller 30 on the cable core. This, in turn, gradually increases the conveying force of the upper rotating roller 30 and the lower rotating roller 31 on the cable core. Furthermore, 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 23 to rotate, the adjusting bevel gear 23 drives the bevel ring 24 to rotate, and the bevel ring 24 drives all the movable sleeves 9 to move away from the fixed plate 21. When the movable sleeves 9 move away from the fixed plate 21, the movable sleeves 9 pull the pull rod 20 through the tension spring 19. The pull rod 20 pulls the fixed plate 21 to press against the inner wall of the protective sleeve, fixing the entrance of the protective sleeve. The fixing force on the protective sleeve gradually increases. The second stepper motor 17 is started. The second stepper motor 17 drives the heating cylinder 12 to rotate through the gear pair. The heating cylinder 12 drives the heating plate to rotate, and the protective sleeve is rotated and heated evenly. The first spur gear 35 rotates, and the first spur gear 35 drives the second spur gear 36 to rotate. The second spur gear 36 drives the connecting rod 2 to move up and down. The connecting rod 2 drives the scissor mechanism 3 to repeatedly extend and retract. The scissor mechanism 3 drives the moving carriage 18 to move back and forth relative to the frame 1, and to heat the protective sleeve back and forth.
