Description

Technical Field

[0001] This application relates to the technical field of cable processing equipment, and in particular to a clamping and braiding device. Background Technology

[0002] Cables, as transmission tools for power and electronic communications, play a vital role in various fields of modern society. With the continuous development of the power and communications industries, the requirements for cable performance are also increasing. Many cables incorporate a metal braided shielding layer, which greatly enhances the cable's ability to protect internal communication signals, making signal transmission more stable and reliable. This effectively reduces the impact of external interference on signals, thereby ensuring the stability of power supply and the accuracy of electronic communications, playing an indispensable role in many fields such as industrial automation, smart homes, and data centers.

[0003] During the connection of cables with other connectors, in order to achieve an effective connection between the conductor and the connector, and to prevent the braided shield from contacting other connectors, the outer insulation of the cable needs to be peeled off to expose the core wire and braided layer. Then, the insulation layer at the ends of the core wire is further peeled off to expose the conductor. The braided layer on the outer surface of the core wire must be treated, such as pushed back or removed. Because the outer insulation layer of the core wire needs to be protected, it cannot be cut by circumferential cutting. Currently, the industry typically relies on manual operation, where operators use tools to cut the braided layer or push it backward, keeping it away from the core conductor. This manual operation method has become the standard practice for handling cable connections.

[0004] However, relying on manual cutting or pushing of the braided layer to the rear has obvious drawbacks. The operation is very cumbersome, requiring workers to spend a lot of time and energy to complete the processing of each cable, resulting in low overall work efficiency and making it difficult to meet the needs of large-scale production and rapid construction. Summary of the Invention

[0005] In order to improve work efficiency, this application provides a clamping and turning weaving device.

[0006] This application provides a clamping and turning weaving device, which adopts the following technical solution: A clamping and twisting braiding device includes a frame, on which a support and fixing mechanism, a bending mechanism, and a twisting mechanism are provided. The support and fixing mechanism is located at one end of the frame for horizontally supporting and fixing a cable. The bending mechanism has a bending hole of adjustable size. After the support and fixing mechanism supports and fixes the cable, the end of the cable passes through the bending hole. The bending mechanism is located in the extension direction of the cable and is used to clamp the cable near its end and bend the braided layer of the cable end outward away from the cable's central axis. The twisting mechanism is located on the side of the bending mechanism opposite to the support and fixing mechanism. The twisting mechanism includes a sleeve and a first driving member. The sleeve faces the wire core after the braided layer is bent and twisted. The first driving member is disposed on the frame and is used to drive the sleeve to move in a direction closer to or away from the wire core.

[0007] By adopting the above technical solution, the frame supports the support and fixing mechanism, the bending mechanism, and the flipping mechanism. When it is necessary to process the braided layer at the end of the cable, the support and fixing mechanism provides horizontal support and fixation for the cable. At this time, the end of the cable passes through the bending hole. Then, the bending mechanism clamps the cable near its end and bends the braided layer at the end of the cable outward away from the cable's central axis. Then, the first driving component drives the sleeve to move towards the wire core. The moving sleeve covers the wire core and pushes the bent and flipped braided layer backward, so that the braided layer at the end of the cable is opened, which facilitates the connection operation of the cable with other connectors. The operation is simple and does not require the staff to spend a lot of time and energy to manually complete the processing of each cable, thus improving work efficiency.

[0008] Preferably, the first driving component includes a base, a screw, and a first driving motor. The sleeve is horizontally fixed on the base, the base is slidably connected to the frame, the first driving motor is horizontally fixed to the frame, the screw is coaxially fixed to the output shaft of the first driving motor, and the screw is rotatably connected to the frame and threaded through the base.

[0009] By adopting the above technical solution, the first drive motor drives the screw to rotate, and the rotation of the screw causes the base to move along the length of the screw, thereby realizing the movement of the drive sleeve towards or away from the wire core.

[0010] Preferably, the frame is provided with a guide rail along the moving direction of the sleeve, and the bottom of the base is provided with a guide groove that cooperates with the guide rail.

[0011] By adopting the above technical solution, the cooperation between the guide rail and the guide groove during the movement of the base helps to improve the stability of the base movement and the accuracy of the sleeve fitting the wire core.

[0012] Preferably, the diameter of the sleeve is larger than the diameter of the wire core, and the end face of the sleeve facing the wire core abuts against the braided layer after bending and curling.

[0013] By adopting the above technical solution, the diameter of the sleeve is larger than the diameter of the wire core, which makes it easier for the sleeve to fit into the wire core. The end face of the sleeve facing the wire core abuts against the braided layer after it is bent and raised. As the sleeve moves, the end face of the sleeve folds the braided layer away from the end of the wire core.

[0014] Preferably, the support and fixing mechanism includes two meshing toothed plates that cooperate with each other and a second driving member for driving the two meshing toothed plates to move toward each other or away from each other. The second driving member is disposed on the frame and located below the two meshing toothed plates.

[0015] By adopting the above technical solution, before clamping and bending the braided layer at the end of the cable, the operator first places the cable between two meshing toothed plates, and then the second driving component drives the two meshing toothed plates to move towards each other to clamp and fix the cable, which is beneficial to the stability of the subsequent bending operation.

[0016] Preferably, the supporting and fixing mechanism has a support plate on the side opposite to the bending mechanism, the support plate is vertically fixed to the frame, and the upper end of the support plate has a vertically formed receiving groove for accommodating cables.

[0017] By adopting the above technical solution, the cable is housed in the receiving groove, and the support plate supports the cable, which facilitates the clamping and fixing operation of the support and fixing mechanism on the cable.

[0018] Preferably, the bending mechanism includes a support base, a turntable, a third driving member, and several clamping plates. The support base is fixedly mounted on the frame, and the turntable is vertically rotatably connected to the support base. The third driving member is mounted on the support base to drive the turntable to rotate. The turntable has a central hole and several actuating grooves surrounding the central hole. One end of each actuating groove is close to the central hole, and the other end extends away from the central hole. Several clamping plates are arranged around the turntable and form the bending hole within the central hole. Each clamping plate is correspondingly provided with a pin extending into the actuating groove. As the turntable rotates, the clamping plates contract or expand towards the central hole.

[0019] By adopting the above technical solution, the support base supports the turntable, the third driving component, and several clamping plates. The third driving component drives the turntable to rotate. When the turntable rotates, the actuating groove pushes the pin, causing the clamping plate to contract or expand towards the central hole, thereby changing the size of the clamping hole. When the cable end passes through the clamping hole, the clamping hole contracts to clamp the cable. Because the clamping position is close to the end, the braided layer bends outward away from the cable's central axis under the action of the clamping force, which is convenient and quick.

[0020] Preferably, the third driving component includes a third driving motor and a gear. The third driving motor is fixedly mounted on the support base, and the gear is coaxially fixedly connected to the output shaft of the third driving motor. The edge of the turntable is provided with teeth that mesh with the gear.

[0021] By adopting the above technical solution, the output shaft of the third drive motor drives the gear to rotate, and the rotation of the gear drives the turntable to rotate through the meshing teeth.

[0022] Preferably, the third drive motor is configured as a servo motor.

[0023] By adopting the above technical solution, the servo motor can rotate in both directions, thereby driving the clamping plate to contract or expand towards the center hole.

[0024] Preferably, the teeth occupy 1 / 6 of the arc area around the turntable.

[0025] By adopting the above technical solution, the rotation range of the turntable can be reasonably controlled, thereby avoiding excessive rotation.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a support and fixing mechanism, a bending mechanism, and a flipping mechanism, wherein the flipping mechanism includes a sleeve and a first driving member, when it is necessary to process the braided layer at the end of the cable, the support and fixing mechanism provides horizontal support and fixation for the cable. At this time, the end of the cable passes through the bending hole, and then the bending mechanism clamps the cable near its end and bends the braided layer at the end of the cable outward away from the central axis of the cable. Then, the first driving member drives the sleeve to move towards the core. The moving sleeve covers the core and pushes the bent and flipped braided layer backward, so that the braided layer at the end of the cable is opened, thereby facilitating the connection operation of the cable with other connectors. The operation is simple and does not require the staff to spend a lot of time and effort to manually complete the processing of each cable, thus improving work efficiency.

[0027] 2. By setting up a base, a screw and a first drive motor, the first drive motor drives the screw to rotate, and the rotation of the screw causes the base to move along the length of the screw, thereby realizing the movement of the drive sleeve towards or away from the wire core.

[0028] 3. By setting guide rails and guide grooves, the cooperation between the guide rails and guide grooves during the movement of the base helps to improve the stability of the base movement and the accuracy of the sleeve fitting the wire core. Attached Figure Description

Detailed Implementation

[0040] The following is in conjunction with the appendix Figure 1-10This application will be described in further detail.

[0041] This application discloses a clamping and turning weaving device, referring to... Figure 1 and Figure 2 The system includes a frame 1, a support and fixing mechanism 2, a bending mechanism 3, and a flipping mechanism 4. The support and fixing mechanism 2, located at one end of the frame 1, horizontally supports and fixes the cable. The bending mechanism 3 has a bending hole 5 of adjustable size. After the support and fixing mechanism 2 supports and fixes the cable, the end of the cable passes through the bending hole 5. The bending mechanism 3, located in the extension direction of the cable, clamps the cable near its end and bends the braided layer of the cable end outwards away from the cable's central axis. The flipping mechanism 4 is located on the side of the bending mechanism 3 opposite to the support and fixing mechanism 2. The flipping mechanism 4 includes a sleeve 41 and a first driving member 42. The sleeve 41 faces the bent and flipped core of the cable. The first driving member 42, mounted on the frame 1, drives the sleeve 41 to move towards or away from the core, achieving the beneficial effect of automatically processing the cable braided layer and improving work efficiency. This is because the coordinated operation of each mechanism replaces manual operation, reducing labor costs and operating time.

[0042] Reference Figure 1 and Figure 3 The support and fixing mechanism 2 includes two meshing toothed plates 21 that cooperate with each other, and a second driving member 22 for driving the two meshing toothed plates 21 to move closer to or further away from each other. The second driving member 22 is mounted on the frame 1 and located below the two meshing toothed plates 21. The meshing toothed plates 21 are plate-shaped with meshing teeth on their surfaces. They can be made of high-strength steel to ensure sufficient strength to fix the cable. Alternatively, the toothed plates can be made of rubber to increase friction with the cable. The second driving member 22 can be a cylinder, which drives the movement of the two meshing toothed plates 21 by the extension and retraction of its piston rod. Alternatively, it can be an electric push rod, which can also drive the two meshing toothed plates 21 closer to or further away from each other. The piston rod of the second driving member 22 is welded to the meshing toothed plates 21 to ensure the stability of the connection. When the second driving member 22 is activated, the two meshing toothed plates 21 move closer to each other, and the meshing of the teeth tightly clamps the cable, thus supporting and fixing the cable. This combination logic can flexibly adjust the clamping force according to the thickness of the cable, ensuring stable support for cables of different specifications.

[0043] Reference Figure 1 and Figure 3A support plate 8 is provided on the side of the support and fixing mechanism 2 away from the bending mechanism 3. The support plate 8 is vertically fixed to the frame 1, and a vertically oriented accommodating slot 9 for accommodating cables is provided at the upper end of the support plate 8. The support plate 8 is generally a rectangular plate structure, and the material can be aluminum alloy, which is lightweight and high-strength. The accommodating slot 9 is rectangular with an flared upper end, and its width is slightly larger than the outer diameter of the cable. This allows it to accommodate the cable and also provides some restraint for the cable. An alternative feature is that the shape of the accommodating slot 9 can be changed to semi-circular. The support plate 8 is fixedly connected to the frame 1 by bolts, making installation convenient and secure. The combination of the support plate 8 and the accommodating slot 9 can assist the support and fixing mechanism 2 in supporting the cable and preventing the cable from shaking during subsequent operations. When the cable is placed in the accommodating slot 9, it works together with the support and fixing mechanism 2 to keep the cable in a stable horizontal state, which is beneficial for subsequent bending and flipping operations.

[0044] Reference Figure 4 and Figure 5 The bending mechanism 3 includes a support base 31, a turntable 32, a third driving component 33, and several clamping plates 34. The support base 31 is fixedly mounted on the frame 1. The turntable 32 is vertically rotatably connected to the support base 31. The third driving component 33 is mounted on the support base 31 to drive the turntable 32 to rotate. (Refer to...) Figure 6 and Figure 7 The turntable 32 has a central hole 10 and several actuating grooves 11 surrounding the central hole 10. One end of each actuating groove 11 is close to the central hole 10, and the other end extends away from the central hole 10. Several clamping plates 34 are arranged around the turntable 32 and form clamping holes 5 within the central hole 10. Each clamping plate 34 has a corresponding pin 12 extending into the actuating groove 11. As the turntable 32 rotates, the clamping plates 34 contract or expand towards the central hole 10. Specifically, the support base 31 is an L-shaped structure made of cast iron to ensure its stability and support capacity. The turntable 32 is a circular disc, which can be made of stainless steel with a smooth surface to reduce friction during rotation. The central hole 10 is located at the center of the turntable 32 and is used for cable routing. The actuating grooves 11 are radially distributed around the central hole 10. The clamping plates 34 can be made of copper alloy, which has a certain degree of elasticity and wear resistance. The pin 12 is cylindrical and made of carbon steel, connected to the clamping plate 34 via an interference fit. The third driving component 33 can drive the turntable 32 to rotate. When the turntable 32 rotates, the actuating groove 11 pushes the pin 12, causing the clamping plate 34 to contract or expand towards the central hole 10, thus changing the size of the bending hole 5. When the cable end passes through the bending hole 5, the bending hole 5 contracts to clamp the cable. Because the clamping position is close to the end, the braided layer will bend outwards away from the cable's central axis under the clamping force. This combination method can precisely control the degree of bending of the braided layer to adapt to different processing needs.

[0045] Reference Figure 8 and Figure 9 The third driving component 33 includes a third driving motor 331 and a gear 332. The third driving motor 331 is fixedly mounted on the support base 31, and the gear 332 is coaxially fixedly connected to the output shaft of the third driving motor 331. The edge of the turntable 32 is provided with teeth 13 that mesh with the gear 332. The third driving motor 331 can be an AC motor of suitable power, characterized by stable speed. The gear 332 and the teeth 13 are generally made of alloy steel to ensure sufficient strength and wear resistance. The gear 332 is connected to the output shaft of the third driving motor 331 by a key to ensure synchronous rotation. When the third driving motor 331 starts, it drives the gear 332 to rotate, and the gear 332 meshes with the teeth 13 on the edge of the turntable 32, thereby driving the turntable 32 to rotate. This transmission method enables precise speed control, ensuring the stable operation of the bending mechanism 3.

[0046] Specifically, the third drive motor 331 is configured as a servo motor, and the meshing tooth 13 occupies 1 / 6 of the arc area around the turntable 32. The servo motor features high precision and high response speed, enabling precise control of the rotation angle of the turntable 32. The meshing tooth 13 occupying 1 / 6 of the arc area around the turntable 32 allows for reasonable control of the turntable 32's rotation range, preventing over-rotation. When the third drive motor 331 is a servo motor, the size of the bending hole 5 can be precisely adjusted according to actual needs, better achieving the bending operation of the braided layer.

[0047] Looking back Figure 1 and Figure 2 The flipping mechanism 4 includes a sleeve 41 and a first driving component 42. The first driving component 42 includes a base 421, a screw 422, and a first driving motor 423. The sleeve 41 is horizontally fixed on the base 421, which is slidably connected to the frame 1. The first driving motor 423 is horizontally fixed to the frame 1. The screw 422 is coaxially fixed to the output shaft of the first driving motor 423 and rotatably connected to the frame 1, with its threads passing through the base 421. Specifically, the sleeve 41 is a cylindrical structure made of plastic, which has a certain degree of flexibility to avoid scratching the wire core. The base 421 is a block structure made of steel to ensure its strength. The first driving motor 423 is a stepper motor, which can precisely control the number of rotation steps. The sleeve 41 is fixedly connected to the base 421 by welding. When the first drive motor 423 starts, it drives the screw 422 to rotate. Since the screw 422 is threaded through the base 421, the base 421 will move along the axial direction of the screw 422, thereby driving the sleeve 41 to move closer to or away from the wire core. This combination logic converts rotational motion into linear motion through the screw 422 transmission, realizing the precise movement of the sleeve 41.

[0048] Reference Figure 1 and Figure 2 The frame 1 is provided with a guide rail 6 along the moving direction of the sleeve 41, and the bottom of the base 421 is provided with a guide groove 7 that mates with the guide rail 6. Specifically, the guide rail 6 is generally a T-shaped guide rail 6, made of stainless steel, which has good wear resistance and guiding properties. The shape of the guide groove 7 is adapted to the guide rail 6, and is in the form of a T-shaped groove. The base 421 achieves a sliding connection through the cooperation of the guide groove 7 and the guide rail 6, which can ensure the stability and straightness of the movement of the base 421. When the base 421 moves under the drive of the first driving member 42, the cooperation of the guide rail 6 and the guide groove 7 can prevent the base 421 from deviating, ensuring that the sleeve 41 moves accurately toward the wire core.

[0049] Reference Figure 1 and Figure 2 The sleeve 41 has a larger aperture than the wire core diameter, and the end face of the sleeve 41 facing the wire core abuts against the bent and raised braided layer. Because the aperture of the sleeve 41 is larger than the wire core diameter, the wire core can pass smoothly through the sleeve 41 as it moves towards the wire core. The end face of the sleeve 41 facing the wire core abuts against the bent and raised braided layer, and during the movement of the sleeve 41, it flips the braided layer backward, moving it away from the end of the wire core. This design effectively achieves the flipping operation of the braided layer, completing the cable processing.

[0050] The implementation principle of the clamping and flipping braiding device in this application embodiment is as follows: the clamping and flipping braiding device provides stable support for the cable through the supporting and fixing mechanism 2, the clamping bending mechanism 3 bends and lifts the braided layer at the end of the cable, and the flipping mechanism 4 flips the bent braided layer backward, realizing the automation of cable braided layer processing. Compared with manual operation, it greatly improves work efficiency and reduces labor costs. The coordinated cooperation between the various mechanisms can be flexibly adjusted according to different cable specifications, which has strong versatility and practicality, and solves the problems of cumbersome and inefficient manual processing in the prior art, providing an efficient and reliable solution for cable connection processing.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
