Description

Technical Field

[0001] The invention belongs to the technical field of metal wire processing, in particular to a precise cutting device for optical fiber and cable processing. Background Art

[0002] Fiber optic cable is a type of communications cable consisting of two or more glass or plastic optical fiber cores that are located within a protective sheath and covered by a plastic PVC outer casing. Signal transmission along the internal optical fibers generally uses infrared rays. Fiber optic communication is one of the important methods of modern information transmission. It has the advantages of large capacity, long relay distance, good confidentiality, no electromagnetic interference, and saving copper.

[0003] When cutting the finished long optical fiber, both sides of the optical fiber need to be fixed on the pressure foot of the cutting equipment. In order to ensure that the optical fiber can be stably clamped, the pressure foot position is usually fixed, and then the cutting blade in the middle pops out to cut the optical fiber. However, this will cause the operator to accurately adjust the cutting point of the optical fiber before clamping it. Relying solely on manual operation will obviously lead to insufficient cutting point accuracy, so the cutting device needs to be improved. Summary of the invention

[0006] The cutting equipment includes a movable slide frame, a movable push plate is slidably connected to the top of the movable slide frame, a diamond blade is slidably connected to the axis at the bottom of the inner wall of the movable push plate, the diamond blade can be inserted into the interior of the movable slide frame, and the movable push plate is always located outside the movable slide frame, a receiver is fixedly connected to the middle of the upper surface of the movable slide frame, monitoring cameras are arranged on both sides of the outer surface of the receiver, and the monitoring cameras directly monitor the lower cutting point of the diamond blade, control push rods are symmetrically arranged on the left and right sides of the outer surface of the movable push plate, and the end of the control push rod away from the movable push plate is slidably connected to a vertical guide rod, and a pressure component is arranged at the bottom of the inner wall of the movable slide frame.

[0007] Furthermore, the number of the extension frames is two, the side of the extension frame is fixedly connected to the side of the main frame, the axis of the inner wall of the power roller is rotationally connected to the bottom of the inner wall of the extension frame through a rotating motor, the outer surface of the power roller is rollingly connected to the outer surface of the groove slide tube, and the inner wall of the sliding clamp and the outer surface of the glass optical fiber are mutually squeezed.

[0008] Further, the inner clamping device comprises a traction base plate, the front and rear sides of the traction base plate are fixedly connected with a sliding push plate, the inner wall of the sliding push plate is fixedly connected with a groove clamping claw on one side close to the grooved slide tube, the inner wall of the groove clamping claw is rotatably connected with a limit roller, the middle part of the limit roller is provided with a groove for accommodating the glass optical fiber, and the glass optical fiber can be clamped and fixed in the process of clamping the limit roller.

[0009] Furthermore, the pressurizing component includes an axial bottom shell, a transfer cylinder is fixedly connected to the middle of the inner wall of the axial bottom shell, a thrust concave plate is slidably connected to the top of the inner wall of the transfer cylinder, both sides of the middle of the inner cavity of the transfer cylinder are fixedly connected to a stamping box through a through opening, and a pressure-bearing slide is slidably connected to the top of the inner wall of the stamping box.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The device can move the main frame significantly through the power rollers on both sides, so as to first determine the approximate cutting point of the diamond blade, and then fine-tune the cutting point of the diamond blade through the control push rod inside the main frame. Through the double insurance, the glass fiber can be accurately cut, effectively solving the problem of insufficient cutting point accuracy of the glass fiber caused by manual operation.

[0013] 2. When the diamond blade moves down to cut the glass optical fiber, the limit rollers on both sides are pushed by the groove clamps to clamp the two sides of the glass optical fiber. In this way, after the glass optical fiber is cut, the two sections of the glass optical fiber can be set up under the clamping action of the inner clamping device and the sliding clamps, thereby avoiding the problem of unbalanced force between the cut-off part of the glass optical fiber and the clamping part on one side of the sliding clamp, which causes the glass optical fiber to break under the action of its own gravity.

[0014] 3. When the diamond blade cuts the glass fiber, the glass fiber here is pushed upward by the thrust concave plate, so the cut will expand rapidly and then break. Since the diamond blade is not in contact with the upper surface of the shaft bottom shell at this time, the diamond blade will not have a cutting effect with the shaft bottom shell, causing its blade wear and accelerating the cutting of the glass fiber. It also avoids the problem that the glass fiber has a tendency to bend downward under the shear stress of the diamond blade, resulting in an uneven cutting surface.

[0015] 4. When the diamond blade is cutting, the device can control the cutting height of the diamond blade in real time through the pressure-bearing base plate at the bottom, thereby effectively controlling the pressure on the main frame to avoid the diamond blade being pushed downward excessively, causing strong cutting and extrusion pressure that exceeds the pressure-bearing range of the main frame, thereby causing damage to the inside of the device.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0026] Example 1, please refer to Figure 1-Figure 5 , the present invention provides a technical solution: a precise cutting device for optical fiber and cable processing, comprising a power frame 1, a cutting device 2 is arranged in the middle of the inner wall of the power frame 1;

[0027] The power frame 1 includes a main frame 11, and an extension frame 12 is symmetrically arranged on the left and right sides of the outer surface of the main frame 11. An inner push block 13 is fixedly connected to the axis of the outer surface of the extension frame 12 away from the power frame 1 through a through hole, and sliding clamps 18 are symmetrically arranged on the front and rear sides of the inner wall of the inner push block 13. A compression hose 16 is fixedly connected to the axis of the inner wall of the extension frame 12 through a through hole, and a grooved slide pipe 14 is fixedly connected to the end of the compression hose 16 away from the extension frame 12. The inner part of the grooved slide pipe 14 is provided with a A glass optical fiber 15 is arranged, and a power roller 17 is symmetrically arranged on one side of the outer surface of the grooved slide tube 14 close to the compression hose 16. The power rollers 17 on the front and rear sides can control the grooved slide tube 14 to perform directional sliding movement through rolling friction. The inner clamping devices 4 are symmetrically arranged on the left and right sides of the inner wall of the main frame 11, and the inner pushing device 5 is arranged at the bottom of the main frame 11. The inner pushing block 13 can control the sliding claws 18 on the front and rear sides to move in a directional manner, so as to clamp the outer surface of the glass optical fiber 15 through the sliding claws 18;

[0028] The cutting device 2 includes a movable slide frame 21, a movable push plate 22 is slidably connected to the top of the movable slide frame 21, a diamond blade 23 is slidably connected to the axis at the bottom of the inner wall of the movable push plate 22, the diamond blade 23 can be inserted into the interior of the movable slide frame 21, and the movable push plate 22 is always located outside the movable slide frame 21, a receiver 24 is fixedly connected to the middle of the upper surface of the movable slide frame 21, monitoring cameras 25 are arranged on both sides of the outer surface of the receiver 24, and the monitoring cameras 25 directly monitor the lower cutting point of the diamond blade 23, control push rods 27 are symmetrically arranged on the left and right sides of the outer surface of the movable push plate 22, and the end of the control push rod 27 away from the movable push plate 22 is slidably connected to a vertical guide rod 26, and a pressure component 3 is arranged at the bottom of the inner wall of the movable slide frame 21.

[0029] There are two extension frames 12, the side of the extension frame 12 is fixedly connected to the side of the main frame 11, the axis of the inner wall of the power roller 17 is rotatably connected to the bottom of the inner wall of the extension frame 12 through a rotating motor, the outer surface of the power roller 17 is rollingly connected to the outer surface of the grooved slide tube 14, and the inner wall of the sliding clamp 18 is mutually squeezed with the outer surface of the glass optical fiber 15. The front and rear sides of the outer surface of the moving slide frame 21 are slidably connected to the inner wall of the main frame 11 through the guide groove, the left and right sides of the inner cavity of the moving slide frame 21 are symmetrically provided with through openings, and the left and right sides of the outer surface of the moving slide frame 21 are fixedly connected to one end of the grooved slide tube 14 away from the extension frame 12 through the through opening. The front and rear sides of the moving push plate 22 are slidably connected to the outer surface of the main frame 11, the outer surface of the vertical guide rod 26 is fixedly connected to the inner wall of the main frame 11, the bottom of the moving slide frame 21 is slidably connected to the upper surface of the inner push device 5, and the glass optical fiber 15 penetrates the moving slide frame 21.

[0030] When the device is used to cut the glass optical fiber 15, the glass optical fiber 15 is inserted into the device. Since the glass optical fiber 15 can smoothly pass through the device, the two ends of the glass optical fiber 15 are extended from the inside of the device and then fixed by the inner push block 13 on the side of the extended frame 12. That is, the inner push block 13 pushes the sliding clamp 18, so that the sliding clamp 18 clamps and fixes the two ends of the glass optical fiber 15.

[0031] The power rollers 17 on the left and right sides can drive the middle moving slide frame 21 to slide left and right along the guide groove of the main frame 11 through the groove slide tube 14 by self-rotation. Since the glass optical fiber 15 always remains in a fixed state at this time, the moving slide frame 21 can move significantly relative to the glass optical fiber 15, thereby significantly changing the cutting point of the diamond blade 23, and then roughly determining the cutting point of the glass optical fiber 15. Then the power rollers 17 stop rotating, and the control push rods 27 on both sides of the moving slide frame 21 can further move the diamond blade 23 slightly by pushing the moving push plate 22 to accurately determine the cutting point of the diamond blade 23. In this process, the receiver 24 monitors the moving trajectory of the diamond blade 23 through the monitoring cameras 25 on both sides, calculates the actual cutting point in advance, and ensures that the diamond blade 23 has a precise cutting effect.

[0032] The push plate 22 is moved to push the diamond blade 23 at the bottom downward. After the diamond blade 23 cuts the top of the glass optical fiber 15, the glass optical fiber 15 will be directly cut off because it is relatively brittle. At this time, the two ends of the glass optical fiber 15 are always clamped and fixed by the sliding jaws 18. Therefore, after the sliding jaws 18 are pulled apart and separated, the segmented glass optical fiber 15 can be pulled out from both sides.

[0033] During the process of the diamond blade 23 moving down to cut the glass optical fiber 15, since the movable slide frame 21 no longer moves, the traction base plates 41 on both sides will pull the symmetrical sliding push plates 42 closer, and push the limiting rollers 44 on both sides through the groove clamps 43 to limit and clamp the two sides of the glass optical fiber 15. In this way, after the glass optical fiber 15 is cut off, the two sections of the glass optical fiber 15 can be set up under the clamping action of the inner clamping device 4 and the sliding clamps 18.

[0034] Example 2, please refer to Figure 1-Figure 8The present invention provides a technical solution: on the basis of the first embodiment, the inner clamping device 4 comprises a traction base plate 41, the front and rear sides of the traction base plate 41 are fixedly connected with a sliding push plate 42, the inner wall of the sliding push plate 42 is fixedly connected with a groove clamping claw 43 on one side close to the grooved slide tube 14, the inner wall of the groove clamping claw 43 is rotatably connected with a limiting roller 44, the middle part of the limiting roller 44 is provided with a groove for accommodating the glass optical fiber 15, and the glass optical fiber 15 can be clamped and fixed in the process of clamping the limiting roller 44. The bottom of the traction base plate 41 is slidably connected with the bottom of the inner wall of the main frame 11, the outer surface of the sliding push plate 42 is slidably connected with one side of the inner wall of the main frame 11, and the middle part of the outer surface of the limiting roller 44 is pressed against the outer surface of the glass optical fiber 15 through the rotating groove.

[0035] The pressurizing component 3 includes an axial bottom shell 31, a transfer cylinder 32 is fixedly connected to the middle of the inner wall of the axial bottom shell 31, a thrust concave plate 33 is slidably connected to the top of the inner wall of the transfer cylinder 32, and both sides of the middle of the inner cavity of the transfer cylinder 32 are fixedly connected to a stamping box 34 through a through-hole, and a pressure slide 35 is slidably connected to the top of the inner wall of the stamping box 34. When the pressure slide 35 is squeezed downward, the pressure inside the stamping box 34 will increase, and then the pressure inside the transfer cylinder 32 connected to the stamping box 34 will increase, so that the thrust concave plate 33 is pushed upward by the push rod, and the groove of the thrust concave plate 33 is adapted to the lower side of the outer surface of the glass optical fiber 15.

[0036] The inner push device 5 includes a pressure-bearing bottom plate 51, and the top of the inner wall of the pressure-bearing bottom plate 51 is evenly provided with vertical slide plates 53 through sliding grooves 52. The top of the vertical slide plate 53 is rollingly connected with a bottom roller 55, and the front and rear ends of the bottom roller 55 are both rotatably connected with a side rotating plate 54. The outer surface of the bottom roller 55 and the bottom of the main frame 11 are mutually pressed, the upper surface of the pressure-bearing bottom plate 51 is fixedly connected with the bottom of the outer surface of the main frame 11, and the front and rear sides of the outer surface of the bottom roller 55 are both slidingly connected with the inner wall of the side rotating plate 54 through preset slots. The side rotating plate 54 controls the bottom roller 55 to rotate through an internal independent rotating motor, and the rotating motor can perform vertical sliding movement on the inner wall of the side rotating plate 54.

[0037] When the diamond blade 23 moves downward, the pressure slides 35 on both sides are first squeezed downward. At this time, the internal pressure of the punch box 34 increases, pressurizing the connected adapter tube 32, and then the thrust concave plate 33 is pushed upward. Since the glass optical fiber 15 has a certain toughness, the thrust concave plate 33 can slightly push the part of the glass optical fiber 15 that is about to be cut upward. When the diamond blade 23 cuts the glass fiber, the glass fiber here is pushed upward by the thrust concave plate 33, so the cutting opening will expand rapidly and then break.

[0038] When the main frame 11 slides left and right, in order to effectively reduce the friction resistance of the main frame 11, bottom rollers 55 that can roll actively are evenly arranged under the main frame 11. When the main frame 11 slides in a certain direction, the bottom rollers 55 can assist the movement of the main frame 11 through rolling friction, thereby ensuring that the movement of the main frame 11 is smooth enough. When the diamond blade 23 cuts, it will exert a downward extrusion force on the main frame 11 through the punch box 34, and then the main frame 11 presses the bottom roller 55 on the corresponding side below. At this time, the two ends of the bottom roller 55 slide down along the sliding groove mouth on the corresponding side of the side rotating plate 54, and then the vertical slide plate 53 presses the pressure-bearing bottom plate 51 to achieve a precise pressure control effect.

[0039] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
