Description

Technical Field

[0001] This invention relates to the field of optical cable sheath cutting equipment, and more specifically to a cutting device and cutting method for optical cable sheath processing. Background Technology

[0002] Optical fiber cables are manufactured to meet optical, mechanical, or environmental performance specifications. They are communication cable assemblies that use one or more optical fibers encased in a protective sheath as the transmission medium and can be used individually or in groups. Optical fiber cables are mainly composed of optical fibers (glass filaments as thin as a hair), a plastic protective sheath, and a plastic outer sheath.

[0003] Existing solutions for cutting the outer sheath of optical cables, such as patent CN201721769548.8: an optical cable outer sheath insulation stripping machine, mostly use circular blades. The adjustment disc rotates, and the adjustment disc drives the motor clamp screw downward, so that the circular blade contacts the optical cable sheath. Then the motor drives the circular blade to cut the sheath.

[0004] However, the above devices have the following drawbacks when in use: the existing devices are large and bulky, making them inconvenient to carry around. Summary of the Invention

[0005] The technical problem to be solved by the present invention is how to provide a compact optical cable sheath cutting device.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A cutting device for processing the outer sheath of optical cables includes a fixed frame and a tool holder rod. The fixed frame is provided with a positioning mechanism, and one end of the tool holder rod is provided with a cutting mechanism. The tool holder rod is slidably connected to the fixed frame, and the tool holder rod can be moved to position itself close to or away from the positioning mechanism.

[0007] The beneficial effects of this invention are: when the cutter holder moves close to the positioning mechanism, it can clamp the optical cable and cut into the cable sheath, thereby achieving the cutting of the cable sheath by rotating the entire cutting device around the cable axis. The cutting device has a simple structure, is easy to operate, and is relatively lightweight compared to existing cutting devices, making it convenient for operators to carry.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the positioning mechanism is a roller shaft, which is rotatably mounted on the fixed frame, and its axis is perpendicular to the moving direction of the tool holder rod.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the cutting mechanism and the roller clamp the optical cable, and when the rotating cutting device cuts the optical cable, the roller can roll around the optical cable, and the cutting device can rotate flexibly.

[0011] Furthermore, there are two rollers, which are arranged side by side with a gap between them, and the trajectory of the cutting mechanism as it moves with the blade holder is located between the two rollers.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the two rollers and the cutting mechanism are three force points for clamping and positioning the optical cable, the optical cable is accurately positioned and its position is not easily shifted.

[0013] Furthermore, it also includes a screw-in device, which is connected to the tool holder rod in a transmission manner and is used to drive the movement of the tool holder rod when the screw-in device rotates.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the rotary advance device drives the tool holder rod to move linearly through rotation, resulting in a compact overall structure.

[0015] Furthermore, it also includes a dial and an indicator arrow, the dial being rotatably mounted on the mounting bracket, and the indicator arrow being fixedly connected to the screw-in device and pointing to the scale on the dial.

[0016] The beneficial effect of adopting the above-mentioned further solution is that existing cutting devices cannot control the cutting depth according to actual usage requirements when cutting and removing the fiber optic cable sheath. The dial is rotatable; when the cutting mechanism contacts the fiber optic cable sheath, the dial is rotated to the 0 mark, aligning with the indicator arrow. Subsequently, as the screw-in device rotates and moves the blade holder rod towards the positioning mechanism, the dial mark pointed to by the indicator arrow represents the depth to which the cutting mechanism has penetrated the fiber optic cable sheath. This solution allows the depth of penetration of the cutting mechanism into the fiber optic cable sheath to be indicated by both the dial and the indicator arrow, and the cutting depth can be controlled according to the dial's markings.

[0017] Furthermore, the screwing device includes a stud, which is rotatably mounted on the fixed frame. One end of the stud is threaded to the other end of the tool holder rod, and the tool holder rod has a circumferential rotation limit.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by rotating the stud, the stud drives the tool holder rod to move linearly back and forth along the stud axis through the thread.

[0019] Furthermore, the screwing device also includes a screwing handle, which is fixedly connected to the other end of the stud.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the screw-in handle facilitates the operation of the stud.

[0021] Furthermore, the cutting mechanism includes an annular blade, which is rotatably mounted on one end of the blade holder rod, and its rotation axis is perpendicular to the moving direction of the blade holder rod.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the ring blade is installed in a ring shape and can be rotated. This design allows the ring blade and the optical cable sheath to generate rolling friction when cutting the optical cable sheath, which helps to make the cutting smooth and efficient.

[0023] Furthermore, the outer wall of the fixing frame is fixed with an anti-slip sleeve.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the anti-slip sleeve is installed on the outer wall of the fixing frame, which makes it easier to grip the fixing frame and perform cutting operations.

[0025] The present invention also provides a cutting method, which is implemented using the cutting device for optical cable sheath processing as described above, and includes the following steps:

[0026] The optical cable is placed between the positioning mechanism and the cutting mechanism. The cutter rod is moved until the cutting mechanism cuts into the optical cable sheath to a preset depth. The cutting device is rotated around the axis of the optical cable until the cutting of the optical cable sheath is completed.

[0027] The beneficial effects are: when the cutter holder moves close to the positioning mechanism, it can clamp the optical cable and cut into the cable sheath, thus the entire cutting device can be rotated around the cable axis to cut the cable sheath. The cutting method is easy to operate. Attached Figure Description

[0036] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0037] like Figures 1-5 As shown, this embodiment provides a cutting device for processing the outer sheath of optical cables, including a fixed frame 1 and a tool holder 4. The fixed frame 1 is provided with a positioning mechanism, and one end of the tool holder 4 is provided with a cutting mechanism 5. The tool holder 4 is slidably connected to the fixed frame 1, and the tool holder 4 can be moved to be close to or away from the positioning mechanism and positioned.

[0038] When the cutter holder 4 moves close to the positioning mechanism, it can clamp the optical cable and cut into the cable sheath, thereby rotating the entire cutting device around the optical cable axis (e.g., Figure 5 The fiber optic cable sheath can be cut by following the direction indicated by the arrow. The cutting device has a simple structure, is easy to operate, and is relatively lightweight compared to existing cutting devices, making it convenient for operators to carry.

[0039] The fixed frame 1 has a C-shaped structure, and the positioning mechanism and the tool holder rod 4 are respectively set at both ends of the C-shaped structure. The positioning mechanism and the cutting mechanism 5 are arranged opposite to each other.

[0040] Based on the above technical solution, the positioning mechanism is a roller 6, which is rotatably mounted on the fixed frame 1, and its axis is perpendicular to the moving direction of the tool holder rod 4.

[0041] The cutting mechanism 5 and the roller 6 clamp the optical cable. When the cutting device is rotating to cut the optical cable, the roller 6 can roll around the optical cable, and the cutting device can rotate flexibly.

[0042] Based on the above technical solution, there are two rollers 6, which are arranged side by side with intervals. The trajectory of the cutting mechanism 5 as it moves with the tool holder rod 4 is located between the two rollers 6.

[0043] like Figure 5 As shown, the two rollers 6 and the cutting mechanism 5 are the three force points that clamp and position the optical cable, ensuring accurate positioning and preventing positional deviation.

[0044] Based on the above technical solution, a screw-in device 2 is also included. The screw-in device 2 is connected to the tool holder rod 4 in a transmission manner and is used to drive the movement of the tool holder rod 4 when the screw-in device 2 rotates.

[0045] The rotary advance device 2 drives the tool holder rod 4 to move linearly through rotation, resulting in a compact overall structure.

[0046] Based on the above technical solution, it also includes a dial 7 and an indicator arrow 8. The dial 7 is rotatably mounted on the fixed frame 1, and the indicator arrow 8 is fixedly connected to the screw-in device 2 and points to the scale on the dial 7.

[0047] Existing cutting devices cannot control the cutting depth according to actual usage requirements when cutting and removing the fiber optic cable sheath. The dial 7 is rotatable; when the cutting mechanism 5 contacts the fiber optic cable sheath, the dial 7 is rotated to the 0 mark, aligning with the indicator arrow 8. Subsequently, as the screw-in device 2 rotates and moves the blade holder rod 4 towards the positioning mechanism, the mark on the dial 7 indicated by the indicator arrow 8 represents the depth to which the cutting mechanism 5 has cut into the fiber optic cable sheath. This solution allows the depth to be indicated by the dial 7 and the indicator arrow 8, enabling control of the cutting depth based on the markings on the dial 7.

[0048] Specifically, the dial 7 and the screw-in device 2 are coaxially arranged, and the scale on the dial 7 is arranged along its circumference.

[0049] The rotary advance device 2 adopts any mechanism that can drive the tool holder rod 4 to move linearly through rotation.

[0050] One embodiment of the screw-in device 2 is as follows: the screw-in device 2 includes a stud 11, the stud 11 is rotatably mounted on the fixed frame 1, one end of the stud 11 is threadedly driven to the other end of the tool holder rod 4, and the tool holder rod 4 has a circumferential rotation limit.

[0051] By rotating the stud 11, the stud 11 drives the tool holder rod 4 to reciprocate linearly along the axial direction of the stud 11 via the thread. Since the stud 11 is threadedly connected to the tool holder rod 4, after the stud 11 is rotated to its position, the threaded structure can achieve the positioning of the tool holder rod 4 without the stud 11 being rotated by an external force.

[0052] For the circumferential rotation limit of the tool holder rod 4, optionally, the tool holder rod 4 is prismatic and the fixing frame 1 has a prismatic hole that matches it. The other end of the tool holder rod 4 is slidably disposed in the prismatic hole. The tool holder rod 4 can only move axially along the prismatic hole and cannot rotate around its axis, thereby achieving circumferential rotation limit; or, the tool holder rod 4 has a key (such as a spline or flat key). The other end of the tool holder rod 4 is slidably disposed in the through hole of the fixing frame. The side wall of the through hole of the fixing frame 1 has a strip keyway with key sliding fit. The tool holder rod 4 can move linearly along the axial direction under the guidance of the key and the keyway.

[0053] Furthermore, the screw-in device 2 also includes a screw-in handle 10, which is fixedly connected to the other end of the stud 11. The screw-in handle 10 facilitates the operation of the stud 11.

[0054] Specifically, the stud 11 has an axial limit. In one specific example, the screw-in device 2 also includes a nut 3, with a limit nut fixed in the middle of the stud 11, such as... Figure 3 As shown, nut 3 is threadedly connected to the fixing bracket 1 and secures the limiting nut inside the fixing bracket 1, preventing the stud 11 from moving downwards along the axis. Simultaneously, screwing in the handle 10 abuts against the lower end of the fixing bracket 1, preventing the stud 11 from moving upwards along the axis. This achieves axial limiting of the stud 11. Alternatively, axial limiting can also be achieved by using a stepped hole or washer within the fixing bracket 1 to hold the limiting nut fixed in the middle of the stud 11.

[0055] Specifically, the indicator arrow 8 is fixed to the outer wall of the screw-in handle 10 and is arranged radially thereafter.

[0056] Specifically, based on the pitch of the stud 11, the relationship between the angle of rotation of the stud 11 around its axis and the distance the tool holder rod 4 moves can be calculated, and the distance the tool holder rod 4 moves at the corresponding angle can be marked on the circumference of the dial 7, thus forming the scale of the dial 7.

[0057] Another embodiment of the screw-in device 2 is as follows: the screw-in device 2 includes a stud 11, which is threadedly connected to the fixed frame 1. One end of the stud 11 is rotatably connected to the tool holder rod 4 (for example, through a bearing connection, or the stud 11 has an annular protrusion along its circumference, and the tool holder rod 4 has an annular groove, with the annular protrusion engaging in the annular groove and rotating along it). In this way, although linear movement of the tool holder rod 4 can be achieved, and optical cable cutting can be realized, the stud 11 will also move linearly relative to the fixed frame 1, making it inconvenient to read the scale 7. Therefore, the first embodiment of the screw-in device 2 is the preferred solution.

[0058] Based on the above technical solution, the cutting mechanism 5 includes an annular blade 9, which is rotatably mounted on one end of the blade holder 4, and its rotation axis is perpendicular to the moving direction of the blade holder 4.

[0059] The ring blade 9 is ring-shaped and rotatable. This design allows the ring blade 9 and the fiber optic cable sheath to generate rolling friction when cutting the cable sheath, which helps to make the cut smooth and efficient.

[0060] Specifically, a slotted notch is provided at one end of the tool holder 4, and the annular blade 9 is rotatably mounted in the slotted notch via a pin.

[0061] Based on the above technical solution, the outer wall of the fixing frame 1 is fixed with an anti-slip sleeve.

[0062] Anti-slip sleeves are provided on the outer wall of the fixed frame 1 to facilitate gripping of the fixed frame 1 and cutting operations.

[0063] The present invention also provides a cutting method, which is implemented using the cutting device for optical cable sheath processing as described above, and includes the following steps:

[0064] The optical cable is placed between the positioning mechanism and the cutting mechanism 5. The cutter rod 4 is moved until the cutting mechanism 5 cuts into the optical cable sheath to a preset depth. The cutting device is rotated around the axis of the optical cable until the cutting of the optical cable sheath is completed.

[0065] When the cutter holder 4 moves close to the positioning mechanism, it can clamp the optical cable and cut into the cable sheath. Rotating the entire cutting device around the cable axis then cuts the cable sheath. The cutting method is easy to operate.

[0066] The cutting method is specifically as follows:

[0067] S1, rotate the screw-in handle 10 to drive the stud 11 to rotate, and convert the rotational force into axial thrust through the helical engagement, so that the stud 11 drives the tool holder rod 4 to move and brings the annular blade 9 close to the roller shaft 6.

[0068] S2, place the optical cable to be cut and stripped between the two rollers 6, and continue to rotate the screw-in handle 10 so that the cutter rod 4 drives the annular blade 9 to move until the annular blade 9 comes into contact with the optical cable sheath;

[0069] S3, rotate the dial 7 until the 0 mark on the dial is aligned with the indicator arrow 8;

[0070] S4. Hold the optical cable with one hand to stabilize it. Calculate the preset cutting depth according to the outer sheath thickness parameters of different models and specifications of optical cables. Observe the distance scale value indicated by the indicator arrow 8 on the scale 7 and rotate the screw-in handle 10 until the indicator arrow 8 points to the scale of the scale 7, which is the preset depth value.

[0071] S5, rotate the cutting device around the optical cable axis. Since the optical cable is fixed, after rotation, the annular blade 9 completes the annular cut on the optical cable sheath. Optionally, a micro motor can be used to drive the annular blade 9 to rotate, which can accelerate the cutting efficiency.
