Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication testing and maintenance technology, and in particular to a device for tightening and loosening nuts for optical fiber connectors. Background Technology

[0002] In modern fiber optic communication systems, the microscopic cleanliness of the fiber optic connector end face, as a core component for achieving precise interconnection of fiber optic links, directly determines the quality of optical signal transmission. If micron-level contaminants adhere to the connector, it can lead to increased insertion loss, decreased signal-to-noise ratio, and even communication interruption. Therefore, periodic high-precision inspection and cleaning of the end face is a key link in ensuring the reliable operation of the system. For FC type fiber optic connectors, the end uses a cylindrical nut with axial grooves for locking, which differs significantly from the traditional polygonal nut structure. However, due to limitations in cable and space, conventional nut tightening mechanisms are difficult to automate. Therefore, the current industry practice is for operators to manually loosen the nut, remove the connector, inspect the end face for contamination level using high-magnification metallographic microscopy, clean it, and then manually tighten the nut to restore the connection. This mode has obvious limitations: First, it is inefficient: manual tightening and coaxiality calibration are time-consuming and difficult to meet the needs of large-scale testing or large-scale operation and maintenance; Second, it lacks stability and reliability: On the one hand, manual tightening is prone to generating radial eccentric force, causing damage such as wear of the connector ceramic ferrule and fiber core misalignment; on the other hand, the differences in personnel operation can easily lead to unstable testing and cleaning effects, and cannot guarantee a unified standard for optical link performance.

An opening and closing assembly is disposed on the first platform. The opening and closing assembly is connected to the driving wheel bracket and the driven wheel bracket respectively, and is used to drive the rotating driving wheel and the positioning driven wheel to move closer or further away from each other along a first direction. A drive component is disposed on the opening and closing component and is connected to the rotary drive wheel for driving the rotary drive wheel to rotate.

[0006] In one embodiment of this utility model, the opening and closing assembly includes a gripper cylinder, a first support, and a second support; the gripper cylinder is fixedly installed on the first platform, and the first support and the second support are respectively connected to two movable parts of the gripper cylinder. The two movable parts move relative to each other in a first direction to drive the first support and the second support to move closer or further apart from each other. The driving wheel bracket is installed on the first support, and the driven wheel bracket is fixedly connected to the second support.

[0007] In one embodiment of the present invention, the opening and closing assembly further includes a first sliding pair and a second sliding pair; the first sliding pair and the second sliding pair are arranged along a first direction; the first support and the first platform are connected through the first sliding pair; the second support and the second sliding pair are connected.

[0008] In one embodiment of the present invention, the drive assembly includes a motor, a first synchronous pulley, a second synchronous pulley, and a synchronous belt. The motor is mounted on the opening and closing assembly. The first synchronous pulley is connected to the output end of the motor. The second synchronous pulley is coaxially fixed with the first rotating drive pulley. The synchronous belt is wound between the first synchronous pulley and the second synchronous pulley.

[0009] In one embodiment of this utility model, two positioning driven wheels are configured, and the two positioning driven wheels are arranged vertically on the driven wheel bracket.

When the fiber optic connector nut is placed into this space, it can be reliably clamped. When the driving assembly rotates the rotating driving wheel, the friction between the driving wheel and the outer wall of the nut enables the loosening or tightening of the nut, avoiding the inefficiency of manual operation. Simultaneously, the opening and closing assembly is mounted on the first platform and connected to the driving wheel bracket and the driven wheel bracket respectively. Under the driving action, it drives the two brackets to move relative to each other along a first direction, thus occupying space radially from the nut without affecting the cable.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0019] See Figures 1 to 5 As shown, this utility model provides a fiber optic connector nut tightening device, including a base plate 100, a first platform 200, a tightening component 300, an opening and closing component 400, and a driving component 500. The first platform 200 is mounted on the base plate 100.

[0020] The tightening assembly 300 includes a drive wheel bracket 310, a rotating drive wheel, a driven wheel bracket 330, and a positioning driven wheel 340. The rotating drive wheel is rotatably mounted on the drive wheel bracket 310. The positioning driven wheel 340 is rotatably mounted on the driven wheel bracket 330. The rotating drive wheel and the positioning driven wheel 340 are arranged opposite to each other, forming a clamping space between them for holding the nut 810 of the fiber optic connector. The surface of the rotating drive wheel is provided with a friction structure to provide a stable frictional torque during tightening. Preferably, the friction structure can be textured to increase friction with the outer wall of the nut 810 and prevent slippage. Alternatively, the friction structure can employ a rubber layer, rubber ring, particle coating, roughening treatment, etc., to adapt to the surface characteristics of the nut and the operating environment.

[0021] The opening and closing assembly 400 is mounted on the first platform 200 and connected to the driving wheel bracket 310 and the driven wheel bracket 330 respectively. It can drive the two to move closer or further apart along a first direction to achieve adjustable clamping space. In this embodiment, the first direction can be understood as a horizontal direction perpendicular to the axis of rotation of the driving wheel or the axis of positioning the driven wheel 340.

[0022] The drive assembly 500 is disposed on the opening and closing assembly 400 and is connected to the rotary drive wheel for driving the rotary drive wheel to rotate.

[0023] Combination Figure 2 In one possible embodiment, the rotating drive wheel includes a first rotating drive wheel 320. The first rotating drive wheel 320 is rotatably mounted on the drive wheel bracket 310 and is capable of stable rotation under the drive of the drive assembly 500. The drive assembly 500 is drively connected to the first rotating drive wheel 320 to provide the power required for tightening. The first rotating drive wheel 320 and the positioning driven wheel 340 are arranged opposite each other, forming a clamping space between them for placing and holding the fiber optic connector nut 810.

[0024] The working principle of the fiber optic connector nut tightening device is as follows: The opening and closing assembly 400 causes the active wheel bracket 310 and the driven wheel bracket 330 to separate, opening the clamping space and facilitating the insertion of the fiber optic connector nut 810. Once the nut 810 is in the clamping position, the opening and closing assembly 400 tightens, causing the rotating active wheel and the positioning driven wheel 340 to respectively adhere to the outer wall of the nut 810 from the side of the fiber optic connector and reliably clamp it. At this time, the drive assembly 500 starts, driving the first rotating active wheel 320 to rotate. Utilizing the friction between the friction structure and the outer wall of the nut 810, the nut 810 can be loosened or tightened.

[0025] Through the combination of the above-described structure and working principle, the fiber optic connector nut tightening device provided in this embodiment of the invention can stably clamp and automatically tighten the fiber optic connector nut 810. Without interfering with the cables of the fiber optic connection machine, it avoids the drawbacks of low efficiency, insufficient operational precision, and easy damage to the fiber optic end face caused by manual tightening, thereby improving the efficiency of nut installation and removal and the stability and safety of the fiber optic testing process. The positioning driven wheel 340, on the one hand, works in conjunction with the rotating drive wheel to position the nut of the fiber optic connector, improving the consistency and stability of the nut 810 tightening process; on the other hand, it provides support force to the nut of the fiber optic connector in the opposite direction of the rotating drive wheel, avoiding large eccentric torque on the fiber optic connector and reducing the risk of damage to the fiber optic connector.

[0026] See Figure 3 and Figure 4 As shown, in another embodiment, the rotating drive wheel includes a first rotating drive wheel 320 and a second rotating drive wheel 350.

[0027] The first rotating drive wheel 320 and the second rotating drive wheel 350 are both rotatably mounted on the drive wheel bracket 310 to form a two-stage transmission structure. Preferably, The second rotating drive wheel 350 and the positioning driven wheel 340 are arranged opposite to each other, forming a clamping space between them, which is used to clamp the nut 810 of the fiber optic connector, so that it remains stably positioned during the tightening process.

[0028] The tensioning assembly 300 also includes a rotary drive wheel bracket 360 and a rotary drive wheel 370. The rotary drive wheel bracket 360 is disposed on the drive wheel bracket 310. The rotary drive wheel 370 is rotatably mounted on the rotary drive wheel bracket 360 via a rotating shaft. The rotary drive wheel 370 is located between the first rotary drive wheel 320 and the second rotary drive wheel 350, and engages with both the first rotary drive wheel 320 and the second rotary drive wheel 350 to form a stable power transmission chain.

[0029] In the operation of this embodiment, when the drive component 500 is started, it drives the first rotating drive wheel 320 to rotate. The power is then transmitted to the second rotating drive wheel 350 through the rotating transmission wheel 370. Finally, the second rotating drive wheel 350 cooperates with the positioning driven wheel 340 to loosen or tighten the fiber optic connector nut 810.

[0030] As the nut 810 is gradually tightened, the second rotary drive wheel 350 gradually decelerates until it stops due to the increased resistance of the nut, while the first rotary drive wheel 320 continues to rotate under the drive assembly 500. Since the first rotary drive wheel 320 and the rotary transmission wheel 370 are in a frictional tangential fit, when the transmitted torque is too large, the two will slide relative to each other, causing the first rotary drive wheel 320 to enter an idling state, thereby preventing the transmission of excessive torque to the second rotary drive wheel 350 and the nut 810.

[0031] Through the above structure and working principle, this embodiment ensures that the nut 810 is reliably tightened, while utilizing the idling characteristic of the first rotating drive wheel 320 to achieve automatic unloading of excessive torque, avoiding the continued transmission of pressure to the fiber optic head after the nut 810 is tightened, thereby effectively alleviating the wear of the fiber optic head 820, and also preventing the nut 810 from being over-locked and difficult to disassemble.

[0032] Furthermore, the rotary transmission wheel bracket 360 is provided with an oblong hole 361, the long axis of which extends along the first direction, so that the rotary transmission wheel bracket 360 can be adjusted in position along the first direction, and after being adjusted to a suitable position, it is fixed to the drive wheel bracket 310 by fasteners.

[0033] By adjusting the position of the rotary transmission wheel bracket 360, the contact pressure between the rotary transmission wheel 370 and the first rotary drive wheel 320 can be controlled, thereby adjusting the tightness of the friction transmission and the idling sensitivity to ensure the stability and adaptability of the power transmission process.

[0034] See Figure 2 As shown, the opening and closing assembly 400 includes a gripper cylinder 410, a first support 420, and a second support 430.

[0035] A gripper cylinder 410 is fixedly mounted on the first platform 200, and the gripper cylinder 410 has movable parts that can move relative to each other. A first support 420 and a second support 430 are respectively fixedly connected to the two movable parts of the gripper cylinder 410. When the gripper cylinder 410 is activated, the two movable parts move relative to each other in a first direction, thereby causing the first support 420 and the second support 430 to move closer or further apart in the first direction.

[0036] The drive wheel bracket 310 is fixedly mounted on the first support 420, and the driven wheel bracket 330 is fixedly mounted on the second support 430. The drive wheel bracket 310 and the driven wheel bracket 330 can move synchronously with the movement of the first support 420 and the second support 430, thereby realizing automatic adjustment of the clamping space.

[0037] During the operation of the opening and closing assembly 400, when the gripper cylinder 410 drives the two moving parts to move outward, the first support 420 and the second support 430 separate accordingly, causing the active wheel bracket 310 and the driven wheel bracket 330 to separate synchronously, so that the clamping space between the rotating active wheel 320 and the positioning driven wheel 340 is opened, making it easier to insert or remove the fiber optic connector nut 810.

[0038] When the nut 810 enters the clamping position, the gripper cylinder 410 drives the two moving parts to move inward, so that the first support 420 and the second support 430 move closer to each other, thereby driving the driving wheel support 310 and the driven wheel support 330 to retract synchronously, so that the rotating driving wheel (the first rotating driving wheel 320 or the second rotating driving wheel 350) and the positioning driven wheel 340 are tightly attached to the outer wall of the nut 810 and a reliable clamping is achieved.

[0039] The automatic opening and closing of the clamping space is achieved by the linear drive of the gripper cylinder 410, avoiding the inconvenience and positioning errors caused by manual operation.

[0040] This embodiment features a compact structure and simple operation, enabling rapid clamping and releasing of the nut. It ensures positioning accuracy and force stability during tightening operations, thereby improving the device's assembly and disassembly efficiency as well as the safety and reliability of the fiber optic testing process.

[0041] See Figures 2 to 3 As shown, the opening and closing assembly 400 also includes a first sliding pair 440 and a second sliding pair 450, both of which are arranged along the first direction.

[0042] The first sliding pair 440 consists of a track 441 and a first slider 442 that cooperates with it. The track 441 is fixedly installed on the first platform 200 along a first direction, and the first support 420 is fixedly connected to the first slider 442, thereby enabling smooth linear sliding on the track 441.

[0043] The second sliding pair 450 consists of a sliding cantilever 451 and a guide block 452. The guide block 452 is fixedly mounted on the first support 420 and provides guiding constraints for the sliding cantilever 451. The sliding cantilever 451 can slide along a first direction on the guide block 452, and its two ends are fixedly connected to the second support 430 and the driven wheel bracket 330, respectively. Through this structure, the sliding cantilever 451 achieves smooth movement under the guidance of the guide block 452, so that the second support 430 and the driven wheel bracket 330 move synchronously. In this embodiment, a slide rail (not shown in the figure) is fixed on the inner side of the sliding cantilever 451 and slides in cooperation with the guide block 452. The sliding cantilever 451 is slidably connected to the guide block 452 through the slide rail.

[0044] During the operation of the device, when the gripper cylinder 410 drives the first support 420 and the second support 430 to reciprocate along the first direction, the first sliding pair 440 ensures that the first support 420 moves smoothly on the track 441, avoiding swaying and jamming. At the same time, the second sliding pair 450, through the cooperation of the sliding cantilever 451 and the guide block 452, ensures that the second support 430 and the driven wheel bracket 330 move synchronously.

[0045] Through the cooperation of the first sliding pair 440 and the second sliding pair 450, the opening and closing assembly 400 can achieve stable clamping space adjustment under the drive of the gripper cylinder 410, effectively avoiding the problem of the first support 420 and the second support 430 shifting or becoming unstable during the movement, thereby ensuring the parallelism and uniform force of the nut 810 clamping, improving the reliability of the clamping action and the overall stability of the device operation.

[0046] See Figure 1 As shown, the drive assembly 500 includes a motor 510, a first synchronous pulley 520, a second synchronous pulley 530, and a synchronous belt 540. The first and second synchronous pulleys 520 and 530 are rotatably mounted on the front of the first support 420, while the motor 510 is mounted on the back of the first support 420. The motor 510 is preferably a stepper motor to ensure positioning accuracy during transmission. The output end of the motor 510 is coaxially and fixedly connected to the first synchronous pulley 520, and the second synchronous pulley 530 is coaxially and fixedly connected to the first rotating drive pulley 320 to ensure synchronous rotation. The synchronous belt 540 is wound between the first and second synchronous pulleys 520, forming a reliable belt drive mechanism.

[0047] During the operation of the drive assembly 500, when the motor 510 starts, its output shaft drives the first synchronous pulley 520 to rotate. The power is transmitted to the second synchronous pulley 530 via the synchronous belt 540, which in turn drives the first rotating drive pulley 320, which is coaxial with it, to rotate synchronously. Since the synchronous belt 540 transmission is a flexible transmission method, it can maintain a stable transmission ratio and speed, while effectively absorbing shock and vibration, avoiding the gap and noise problems that may occur in gear meshing transmission.

[0048] Through the above structure, the drive assembly 500 uses the motor 510 as a power source, and in conjunction with the synchronous pulley and synchronous belt 540, it realizes stable drive of the first rotating drive wheel 320, thereby ensuring the smoothness and consistency of the nut 810 tightening process, which not only improves the disassembly and assembly efficiency, but also extends the service life of the device.

[0049] See Figure 2As shown in Figure 3, the tensioning assembly 300 has two positioning driven wheels 340, which are arranged vertically on the driven wheel bracket 330. The two positioning driven wheels 340 are rotatably mounted on the upper and lower positions of the driven wheel bracket 330 via a rotating shaft, and are distributed at intervals in the vertical direction, forming a corresponding clamping area with the rotating driving wheel.

[0050] When the opening / closing assembly 400 drives the driving wheel bracket 310 and the driven wheel bracket 330 to approach each other, the two positioning driven wheels 340 can simultaneously contact the outer wall of the nut 810 and clamp the nut 810 in cooperation with the rotating driving wheel. Due to the use of two vertically arranged positioning driven wheels 340, not only are three clamping points formed that contact the nut 810, improving the accuracy of clamping and positioning, but a more uniform clamping force can also be applied to the nut 810, avoiding uneven force distribution and nut 810 offset problems that may be caused by clamping with a single positioning driven wheel 340.

[0051] See Figure 5 As shown, the fiber optic connector nut tightening device also includes a detection component 700, which includes a second platform 710, a port bracket 720, and a test port connector 730.

[0052] The second platform 710 is mounted on the base plate 100, the port bracket 720 is fixedly mounted on the second platform 710, and the test port connector 730 is disposed on the port bracket 720. Its insertion direction is the second direction, which is perpendicular to the first direction. The second direction can be understood as a horizontal direction parallel to the axis of the rotating driving wheel or the axis of the positioning driven wheel 340.

[0053] When testing the fiber optic connector, the FC fiber optic head 820 is inserted and axially positioned into the test port connector 730 along the second direction, forming axial limit and coaxial constraint on the fiber optic head end face, and then the nut 810 is tightened. When cleaning the fiber optic connector, the nut 810 is loosened, and then the FC fiber optic head 820 is pulled out from the test port connector 730 along the second direction. When tightening and loosening the nut 810, the opening and closing component 400 moves along the first direction, bringing the first rotating drive wheel 320 (or the second rotating drive wheel 350, depending on the implementation of the tightening and loosening component 300) closer to the positioning driven wheel 340, clamping the connector nut 810; then the drive component 500 drives the first rotating drive wheel 320 or the second rotating drive wheel 350 to rotate, thereby loosening or tightening the nut 810. It should be noted that the FC type fiber optic connector includes an FC fiber optic head 820, a nut 810, and a fiber optic cable 830. The nut is fitted onto the FC fiber optic head 830, and the fiber optic cable 830 is connected to the FC fiber optic head 820.

[0054] See Figure 1As shown, the fiber optic connector nut tightening device also includes a third sliding pair 600.

[0055] The third sliding pair 600 includes a second track 610 and a second slider 620 that slides with it. The second track 610 is fixedly mounted on the base plate 100, and the first platform 200 is fixedly disposed on the second slider 620. With this structure, the first platform 200 can achieve smooth linear sliding along the direction of the second track 610.

[0056] During the operation of the fiber optic connector nut tightening device, when the drive assembly 500 drives the first rotating drive wheel 320 to tighten the nut 810, the nut 810 will undergo a slight displacement along its axial direction. At this time, the first platform 200, with the cooperation of the third sliding pair 600, can automatically translate along the second direction with the nut 810, realizing the adaptive advance and retreat of the tightening assembly 300. This avoids the nut 810 being subjected to excessive axial tension or compression during tightening, effectively reducing the risk of damage to the connector and fiber optic head.

[0057] See Figure 5 As shown, the detection assembly 700 also includes an optical fiber head support 740. The optical fiber head support 740 is disposed on the second platform 710, and has an optical fiber head fixing groove 741 thereon.

[0058] After the fiber optic head is removed or when not in use, it can be placed in the fiber optic head fixing slot 741. The slot provides restraint and support for the fiber optic head, preventing damage to the end face due to shaking or collision. When the fiber optic head is placed in the fixing slot, its end face can also be cleaned, facilitating the timely removal of dust or oil before and after testing, ensuring the cleanliness of the fiber end face and the accuracy of testing. This structural design not only ensures the safe storage of the fiber optic head before and after testing but also facilitates simultaneous maintenance and cleaning, thereby further improving the convenience and reliability of the testing operation.

[0059] See Figure 5 As shown, the detection component 700 also includes a winder 750 and a winder slot 760. The winder slot 760 is located on the second platform 710, and the winder 750 is disposed within the winder slot 760 for storing and managing the fiber optic cable 830. The fiber optic cable 830 can be orderly wound by the winder 750, thus avoiding bending or damage caused by haphazardly stacking the fiber optic cable 830 on the platform surface. This facilitates operation and extends the service life of the fiber optic cable 830.

[0060] Specifically, the cable winder 750 has a frame-like structure with two symmetrically arranged central limiting posts 751 inside. The outer surfaces of the two central limiting posts 751 and the inner wall of the cable winder 750 together form an annular winding space. The fiber optic cable 830 can be coiled and stored in this annular space in a circular shape, thereby avoiding bending or damage caused by random stacking and ensuring the orderliness and safety of cable management.
