Description

Technical Field

[0001] This application relates to the field of stranded wire technology, and in particular to a stranded wire mechanism for a shell insertion machine. Background Technology

[0002] The connector housing is a core component that ensures the stability and reliability of cable connections. The housing typically integrates multiple functional wires to transmit electrical energy or signals. Since directly assembling multiple independent wires into the housing can easily lead to problems such as messy wiring, weak anti-interference ability, and insufficient mechanical strength, the multiple wires are twisted together after assembly to form an integrated twisted bundle. This process not only reduces the impact of external electromagnetic interference on signal transmission but also enhances the tensile and bending resistance of the wires.

[0003] In related technologies, a first gripper cylinder holds multiple threads to be processed at one end near the insert shell. The first gripper cylinder slides along the guide rail away from the insert shell, straightens and tightens the threads, and then drives the motor to rotate further to achieve the twisting operation of multiple threads.

[0004] However, in high-speed stranding operations, the slight fluctuations in the air source pressure are amplified, causing the clamping force of the first gripper cylinder to fluctuate dynamically, which in turn leads to drastic changes in the tension of the strand. This can easily cause the stranded bundle to become loose or overly tight after rotation, affecting the pitch uniformity and structural stability of the stranded wire. Utility Model Content

[0005] To address the aforementioned problems, this application provides a stranding mechanism for a casing insertion machine.

[0006] The present application provides a wire stranding mechanism for a shell insertion machine, which adopts the following technical solution: it includes a base, a wire stranding assembly, and a pressure monitoring assembly. The wire stranding assembly is slidably disposed on the base. The wire stranding assembly includes a first gripper cylinder and a drive motor. The output shaft of the drive motor is fixedly connected to the first gripper cylinder. The pressure monitoring assembly is fixed to the first gripper cylinder and is connected to the air inlet of the first gripper cylinder and an external air supply device. The pressure monitoring assembly is electrically connected to the drive motor.

[0007] By adopting the above technical solution, after multiple wires are assembled into the housing, the first gripper cylinder holds the end of the wire near the housing. The drive motor, fixedly connected to the first gripper cylinder, drives the first gripper cylinder and the drive motor to slide along the machine base away from the housing. During the sliding process, the first gripper cylinder continuously and stably holds the wire and gradually straightens and tidies up the scattered wires until they move to the ends of the multiple wires away from the housing and are completely straightened. Then, the drive motor starts to rotate, synchronously driving the first gripper cylinder to rotate, thereby completing the twisting operation of multiple wires. During this process, the air pressure monitoring system connected to the air inlet of the first gripper cylinder... The measuring component collects real-time air pressure data from the first gripper cylinder. The tension generated by the tensioning of the yarn acts on the piston of the first gripper cylinder through the clamping surface, causing the air pressure in the first gripper cylinder to fluctuate accordingly with the change in tension. This allows the real-time monitored air pressure signal to be accurately converted into the actual tension of the yarn. This tension data is then fed back to the drive motor, adjusting the rotation speed of the drive motor to achieve real-time matching between the stranding speed and the yarn tension. This solves the problem of dynamic fluctuations in the clamping force of the first gripper cylinder caused by the amplification of small air pressure fluctuations in high-speed stranding scenarios, and improves the uniformity of the stranding pitch and the structural stability of the yarn stranding.

[0008] Preferably, the air pressure monitoring component includes a three-way connector and an air pressure sensor. The main inlet in the middle of the three-way connector is connected to an external air supply device. One of the branches at both ends of the three-way connector is connected to the air pressure sensor, and the other branch at both ends of the three-way connector is connected to the air inlet of the first gripper cylinder.

[0009] By adopting the above technical solution and through the reasonable diversion design of the three-way connector, while ensuring that the air supply device stably delivers compressed air to the first gripper cylinder to meet the clamping requirements, the air pressure sensor connected to the branch end can collect the air pressure data of the air inlet of the first gripper cylinder in real time, realizing the synchronous monitoring of air pressure and clamping force. The dual functions of air supply and monitoring can be completed with only a single three-way connector, simplifying the air circuit layout while ensuring the timeliness and accuracy of pressure monitoring.

[0010] Preferably, the air pressure monitoring component further includes a filter pressure reducing valve, which is disposed between the external air supply device and the three-way connector. The air inlet of the filter pressure reducing valve is connected to the external air supply device, and the air outlet of the filter pressure reducing valve is connected to the main inlet of the three-way connector.

[0011] By adopting the above technical solution, the slight pressure fluctuations of the air source itself are greatly attenuated by the pressure regulation of the filter pressure reducing valve, ensuring that the air pressure of the input three-way connector and the first gripper cylinder is always within a stable range, providing an accurate monitoring benchmark for the air pressure sensor. The stable air pressure signal can make the conversion of the wire tension more accurate, providing more reliable data support for dynamically adjusting the speed of the drive motor, and reducing the impact of air pressure fluctuations on the clamping force in high-speed stranding scenarios.

[0012] Preferably, the air pressure monitoring component further includes a mounting plate, on which the three-way connector, the air pressure sensor, and the filter pressure reducing valve are all mounted, and the mounting plate is fixed to the side wall of the first gripper cylinder.

[0013] By adopting the above technical solution, the mounting plate integrates the originally scattered gas circuit components into a compact module through the centralized installation of the three-way connector, air pressure sensor and filter pressure reducing valve, thus optimizing the overall spatial layout.

[0014] Preferably, the device further includes a controller, which is fixed to the base and electrically connected to the pressure sensor and the drive motor.

[0015] By adopting the above technical solution, the controller converts the air pressure signal into the actual tension value of the yarn through electrical connection with the air pressure sensor and the drive motor. Then, it dynamically outputs speed adjustment commands according to the tension changes, and the speed of the drive motor is adjusted accordingly, so as to realize the real-time adaptation of the yarn tension and the stranding speed.

[0016] Preferably, it further includes a drive sliding assembly, the drive sliding assembly including a first linear module, the first linear module being fixed on the base, and the drive motor and the first gripper cylinder being slidably disposed on the first linear module.

[0017] By adopting the above technical solution, when the first gripper cylinder clamps the line close to one end of the insert shell, the first straight module can drive the first gripper cylinder and the drive motor to slide synchronously away from the insert shell, gradually straightening and tightening the dispersed line until the first gripper cylinder and the drive motor move to the end of the line away from the insert shell, ensuring that the line is in a completely straight state.

[0018] Preferably, the stranding assembly further includes a second gripper cylinder, which is slidably disposed on the base and close to the insert housing.

[0019] By adopting the above technical solution, the second gripper cylinder can pre-clamp the ends of multiple wires near the insert shell before the first gripper cylinder clamps the wire, thus achieving initial stabilization of the relative positions of the ends of multiple wires with the insert shell. When the first straightening module drives the first gripper cylinder and the drive motor to slide backward to straighten the wire, the end of the wire near the insert shell remains in a fixed position due to the fixation of the second gripper cylinder, ensuring that the tension can be evenly applied to the entire wire, achieving smooth straightening of the wire, reducing wire twisting and uneven force caused by loose ends of multiple wires. At the same time, the stable initial position can reduce additional fluctuations in wire tension during subsequent stranding, further improving the uniformity of stranding pitch and structural stability.

[0020] Preferably, the first gripper cylinder includes a gripper, the gripper includes a first gripper arm and a second gripper arm, both the first gripper arm and the second gripper arm are fixedly provided with limit plates, the first gripper arm and the second gripper arm clamp the wire bundle, and the ends of the two limit plates away from the first gripper arm and the second gripper arm abut against each other.

[0021] By adopting the above technical solution, the limiting plates fixed on the first and second clamping arms of the gripper abut against each other at the ends away from the clamping arms when clamping the wire bundle, forming a limiting structure. This can control the maximum closing stroke of the first and second clamping arms and ensure that the tightness of each clamping is consistent, thus achieving standardized clamping of the wire bundle. At the same time, the limiting structure ensures that the wire bundle is always between the first and second clamping arms during the clamping process, reducing the problem of wire deviation or slippage.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. After the wires are inserted into the housing, the first gripper cylinder holds multiple wires near the end of the housing. The drive motor and the first gripper cylinder slide away from the housing to straighten the multiple wires until the ends are straight. Then, the drive motor drives the first gripper cylinder to rotate to complete the stranding. During the process, the air pressure monitoring component collects the air pressure inside the first gripper cylinder in real time. The air pressure fluctuation caused by the tension of the wires acting on the piston rod of the first gripper cylinder is used to convert the air pressure signal into actual tension and feed it back to the drive motor. The speed of the drive motor is dynamically adjusted to match the tension. This effectively solves the problem of clamping force fluctuation caused by the amplification of small air source fluctuations at high speeds, and significantly improves the uniformity of strand pitch and the structural stability of wire stranding.

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a stranding mechanism for a casing insertion machine. (Refer to...) Figure 1 The device includes a base 1, a stranding assembly, a pneumatic pressure monitoring assembly 5, and a drive sliding assembly 6. The stranding assembly is slidably mounted on the base 1. The stranding assembly includes a first gripper cylinder 2 and a drive motor 3. The pneumatic pressure monitoring assembly 5 is connected to the air inlet of the first gripper cylinder 2 and an external air supply device, and the pneumatic pressure monitoring assembly 5 is electrically connected to the drive motor 3. The drive sliding assembly 6 is fixed on the base 1, and the drive motor 3 and the first gripper cylinder 2 are slidably mounted on the drive sliding assembly 6.

[0029] This explains that after multiple wires b are assembled into the housing a, the first gripper cylinder 2 holds one end of the wire b close to the housing a. The drive sliding component 6 can drive the first gripper cylinder 2 and the drive motor 3 to slide synchronously away from the housing a. During the sliding process, the first gripper cylinder 2 continuously and stably holds the wire b and gradually straightens and tidies up the dispersed wires b until they move to the ends of the multiple wires b away from the housing a and are completely straightened. Then the drive motor 3 starts to rotate, synchronously driving the first gripper cylinder 2 to rotate, thereby completing the twisting operation of the multiple wires b.

[0030] Meanwhile, during this process, the air pressure monitoring component 5, which is connected to the air inlet of the first gripper cylinder 2, collects the air pressure data in the first gripper cylinder 2 in real time. The tension generated by the tensioning of the wire b will react on the piston of the first gripper cylinder 2 through the clamping surface, causing the air pressure in the first gripper cylinder 2 to fluctuate accordingly with the change of tension. The real-time monitored air pressure signal can be accurately converted into the actual tension of the wire b. This tension data is then fed back to the drive motor 3, adjusting the rotation speed of the drive motor 3 to achieve real-time matching between the stranding speed and the tension of the wire b. This solves the problem of dynamic fluctuations in the clamping force of the first gripper cylinder 2 caused by the amplification of small air source pressure fluctuations in high-speed stranding scenarios, and improves the uniformity of the stranding pitch and the structural stability of the stranding of the wire b.

[0031] Reference Figure 2 Specifically, the stranding assembly also includes a second gripper cylinder 4, and a first gripper cylinder 2 includes a gripper 21 for gripping multiple strands of wire b to be processed. The gripper 21 of the first gripper cylinder 2 includes a first gripping arm 211 and a second gripping arm 212. Both the first gripping arm 211 and the second gripping arm 212 are fixedly provided with limit plates 213. When the first gripping arm 211 and the second gripping arm 212 grip the strand of wire b, the ends of the two limit plates 213 away from the first gripping arm 211 and the second gripping arm 212 abut against each other to form a limit structure. This can control the maximum closing stroke of the first gripping arm 211 and the second gripping arm 212, and also ensure that the tightness of each gripping is consistent, thus achieving standardized gripping of the strand of wire b. At the same time, the limit structure ensures that the strand of wire b is always between the first gripping arm 211 and the second gripping arm 212 during the gripping process, reducing the problem of wire b shifting or slipping.

[0032] Furthermore, in this embodiment, the first gripper cylinder 2 is a common pneumatic first gripper cylinder 2, which is made of aluminum alloy. Aluminum alloy has the characteristics of being lightweight and having high strength. The drive motor 3 is a servo motor. The servo motor has a fast response speed and can better adapt to the speed adjustment when the tension changes. The output shaft of the drive motor 3 is fixedly connected to the first gripper cylinder 2. When the drive motor 3 rotates, it can drive the first gripper cylinder 2 to rotate together, thereby realizing the twisting operation of multiple wires b.

[0033] Furthermore, the drive sliding assembly 6 includes a first linear module 61, a second linear module 62, a first sliding seat 63, and a second sliding seat 64. The first linear module 61 and the second linear module 62 are fixed to the side wall of the base 1 and are perpendicular to each other. The drive motor 3 is fixed to the first sliding seat 63, and the first sliding seat 63 is slidably disposed on the first linear module 61. When the first gripper cylinder 2 clamps the wire b close to one end of the insert a, the first linear module 61 can drive the first gripper cylinder 2 and the drive motor 3 to slide synchronously away from the insert a, gradually straightening and tightening the dispersed wire b until the first gripper cylinder 2 and the drive motor 3 move to the end of the wire b away from the insert a, ensuring that the wire b is in a completely straightened state.

[0034] Meanwhile, the second gripper cylinder 4 is fixed to the second sliding seat 64, which is slidably disposed on the second linear module 62. The second gripper cylinder 4 is close to the insert a. Before the first gripper cylinder 2 clamps the wire b, the second linear module 62 can drive the second gripper cylinder 4 to move towards the end of the multiple wires b near the insert a. The second gripper cylinder 4 clamps the end of the multiple wires b near the insert a in advance, realizing the initial stabilization of the relative position between the ends of the multiple wires b and the insert a. Then, the first linear module 61 drives the first gripper cylinder 2 and the drive motor 3 to move, and the first gripper cylinder 2 clamps the multiple wires b.

[0035] Furthermore, when the first linear module 61 drives the first gripper cylinder 2 and the drive motor 3 to slide backward to straighten the linear body b, the end of the line body b near the insert a remains in position due to the fixation of the second gripper cylinder 4, ensuring that the tension can be evenly applied to the entire line body b, achieving smooth straightening of the line body b, reducing the problems of line body b twisting and uneven force caused by the loosening of the ends of multiple lines body b. At the same time, the stable initial position can reduce the additional fluctuation of the tension of the line body b during the subsequent stranding process, further improving the uniformity of the stranding pitch and the structural stability.

[0036] Reference Figure 3 Specifically, the air pressure monitoring component 5 includes a three-way connector 51, an air pressure sensor 52, a filter pressure reducing valve 53, and a mounting plate 54. The main inlet located in the middle of the three-way connector 51 is connected to an external air supply device. One branch end of the three-way connector 51 is connected to the air pressure sensor 52, and the other branch end is connected to the air inlet of the first gripper cylinder 2. The air pressure sensor 52 collects the pressure data of the air inlet of the first gripper cylinder 2 in real time through the three-way connector 51. The air pressure sensor 52 is a capacitive air pressure sensor 52, which has the characteristics of high accuracy and fast response speed. Through the reasonable flow distribution setting of the three-way connector 51, while ensuring that the air supply device stably delivers compressed air to the first gripper cylinder 2 to meet the clamping requirements, it can also collect the air pressure data of the air inlet of the first gripper cylinder 2 in real time through the air pressure sensor 52 connected to the branch end, realizing the synchronous monitoring of air pressure and clamping force. The dual functions of air supply and monitoring can be completed through the three-way connector 51 alone, simplifying the air circuit layout while ensuring the timeliness and accuracy of pressure monitoring.

[0037] In addition, this application embodiment also includes a controller 7, which is fixed on the base 1 and electrically connected to the air pressure sensor 52 and the drive motor 3. The controller 7 converts the air pressure signal into the actual tension value of the thread b, and then dynamically outputs speed adjustment commands according to the tension change. The speed of the drive motor 3 is adjusted accordingly to realize the real-time adaptation between the tension of the thread b and the stranding speed. In this application embodiment, the controller 7 adopts a small PLC controller 7. The small PLC has high-speed computing and processing capabilities and can quickly receive the analog signal transmitted by the air pressure sensor 52. Through the algorithm model preset by the small PLC, the air pressure signal is accurately converted into the actual tension value of the thread b. At the same time, the pulse signal is output to the drive motor 3 in real time to adjust the stranding rotation speed of the drive motor 3, so as to realize the dynamic adaptation between tension and stranding speed.

[0038] Furthermore, the filter pressure reducing valve 53 is located between the external air supply device and the three-way connector 51. The air inlet of the filter pressure reducing valve 53 is connected to the external air supply device, and the air outlet is connected to the main inlet of the three-way connector 51. The filter pressure reducing valve 53 has a pressure stabilization and regulation function. The pressure stabilization and regulation significantly reduces the small pressure fluctuations in the air source itself, ensuring that the air pressure input to the three-way connector 51 and the first gripper cylinder 2 is always within a stable range. This provides an accurate monitoring benchmark for the air pressure sensor 52. The stable air pressure signal can make the conversion of the tension of the wire b more accurate, providing more reliable data support for dynamically adjusting the speed of the drive motor 3, and reducing the impact of air pressure fluctuations on the clamping force in high-speed stranding scenarios.

[0039] In addition, a flexible air pipe 55 is provided between the three-way connector 51, the air pressure sensor 52, the filter pressure reducing valve 53 and the first gripper cylinder 2. Specifically, the air inlet of the filter pressure reducing valve 53 is connected to an external air supply device, and the air outlet of the filter pressure reducing valve 53 is connected to the main inlet of the three-way connector 51 through the flexible air pipe 55. One branch of the three-way connector 51 is connected to the air path interface of the air pressure sensor 52 through the flexible air pipe 55 to realize the acquisition of air pressure signals. The other branch of the three-way connector 51 is connected to the air inlet of the first gripper cylinder 2 through the flexible air pipe 55 to provide a stable air source for the cylinder. It should be noted that the first gripper cylinder 2 needs to slide along the base 1 with the first linear module 61, and at the same time, it needs to rotate at high speed with the drive motor 3. The flexible air pipe 55 can follow these dynamic movements through its own bending deformation.

[0040] Meanwhile, the mounting plate 54 is used to install the tee connector 51, the air pressure sensor 52, and the filter pressure reducing valve 53. In this embodiment, the mounting plate 54 is an L-shaped plate, which is composed of two mutually perpendicular plates. One plate is fixed to the side wall of the first gripper cylinder 2 to form a fixed end that is rigidly connected to the first gripper cylinder 2. The other plate serves as a bearing end and extends perpendicularly to the longitudinal plate. The tee connector 51, the air pressure sensor 52, and the filter pressure reducing valve 53 are fixed in an orderly manner on the transverse plate.

[0041] This demonstrates that the vertical structure of the L-shape makes full use of the three-dimensional space of the side wall of the first gripper cylinder 2, reducing the overall volume. The horizontal plate realizes the centralized fixation of the three-way connector 51, the air pressure sensor 52 and the filter pressure reducing valve 53. The rigid connection between the vertical plate and the first gripper cylinder 2 ensures that the three-way connector 51, the air pressure sensor 52 and the filter pressure reducing valve 53 slide and rotate synchronously with the first gripper cylinder 2.

[0042] The implementation principle of the stranding mechanism of the inserting machine according to an embodiment of this application is as follows: After multiple wires b are assembled into inserts a, the second linear module 62 drives the second gripper cylinder 4 to slide towards the end of the multiple wires b near the insert a, pre-clamping the end of the wires b to achieve pre-fixation and ensure the relative position of the wires b and the insert a is stable. Subsequently, the first gripper cylinder 2 precisely clamps the corresponding end of the wires b. The first linear module 61 drives the first gripper cylinder 2 and the drive motor 3 to slide synchronously away from the insert a. During the sliding process, the first gripper cylinder 2 maintains a standardized clamping state through the first gripper arm 211 and the second gripper arm 212 with limit plates 213. During the sliding process, the dispersed wires b are gradually straightened and rectified until they are moved to the end of the wires b and completely straightened. After the wires b are straightened, the drive motor 3 starts to rotate, driving the first gripper cylinder 2 to rotate synchronously, thereby realizing the stranding operation of multiple wires b.

[0043] During the above process, the compressed air output by the external air supply device is filtered for impurities and its pressure is stabilized by the filter pressure reducing valve 53. Then, it is delivered to the main inlet of the three-way connector 51 through the flexible air pipe 55. The three-way connector 51 diverts the stable air source to the first gripper cylinder 2 to ensure the gripping requirements. At the same time, it transmits the air pressure signal to the air pressure sensor 52. The tension generated when the wire b is twisted reacts to the piston of the first gripper cylinder 2 through the gripping surface, causing the air pressure in the first gripper cylinder 2 to fluctuate accordingly with the change of tension. The air pressure sensor 52 captures the air pressure data in real time and transmits it to the controller 7 fixed to the base 1.

[0044] The controller 7 accurately converts the air pressure signal into the actual tension value of the wire b through a preset algorithm model, and then dynamically outputs pulse speed adjustment commands according to the tension changes to adjust the rotation speed of the drive motor 3 in real time, so that the stranding speed and the tension of the wire b are always matched.

[0045] Throughout the process, the mounting plate 54 drives the three-way connector 51, the air pressure sensor 52, and the filter pressure reducing valve 53 to slide and rotate synchronously with the first gripper cylinder 2. The flexible air tube 55 adapts to the dynamic movement through its own bending deformation, while the filter pressure reducing valve 53 continuously attenuates the small fluctuations in the air source, providing a stable benchmark for tension monitoring. Ultimately, this effectively solves the problem of dynamic fluctuations in clamping force under high-speed scenarios, and achieves precise control of the uniformity of strand pitch and structural stability.

[0046] 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.
