Description

Technical Field

[0001] The invention relates to the field of cutting technology, and more specifically, to cutting equipment for flame-retardant steel wire armored temperature-sensitive optical cables. Background Art

[0002] Authorization announcement number CN117817138B, named as a Chinese patent document of an optical cable cutting device, discloses a cutting device specifically for optical cables, which mainly clamps the optical cable by a pair of bearing plates respectively arranged on the left and right sides of the workbench, and uses a driving electric drive to drive the driving wheel to rotate to rub the surface of the optical cable, so that the optical cable is continuously driven away from the center of the workbench, thereby keeping the optical cable in a taut state, and then starting the driving cylinder to push the laser cutting head to move, and cut the taut optical cable.

[0003] The structure of an optical cable generally includes an optical fiber and a sheath that wraps the optical fiber. The above-mentioned cutting equipment only uses a laser cutting head, which is more suitable for cutting optical fibers with ordinary sheaths. For flame-retardant temperature-sensitive optical cables with steel wire armor, the high-temperature-resistant sheath has steel wire and filling materials inside, and the melting temperatures of the materials vary greatly. If only laser cutting is used, the power needs to be set for the material with the highest melting temperature. However, this power is also likely to cause adverse effects on other materials during cutting, such as material melt accumulation around it, which affects the effect of cutting the optical cable. Summary of the invention

DETAILED DESCRIPTION

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

When a component is referred to as being "connected to" another component, it can be directly or indirectly connected to the other component.

[0029] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] like Figure 1The structure of the flame-retardant steel wire armored temperature-sensitive optical cable shown in the figure uses steel wire 101 wound around optical fiber 102 to make the optical cable have mechanical properties of compression and tensile resistance. The space between the steel wire 101 and the optical fiber 102 is filled with grease 103 to block water and increase thermal conductivity. A layer of sheath 104 is wrapped around the steel wire 101, such as a low-smoke halogen-free polyolefin LSZH sheath, which has the effect of waterproofing and flame retardancy. The sheath 104 of the temperature-sensitive optical cable is flame-retardant and high-temperature resistant, and the steel wire 101 is arranged inside. If it is directly cut by laser, it is easy to produce material melting and accumulation, and the cutting effect is not good.

[0032] To this end, the present invention provides a cutting device mainly used for flame-retardant steel wire armored temperature-sensitive optical cables, which uses a left clamping component 1 and a right clamping component 2 to clamp the optical cable 10, and uses an electric saw component 3 to rotate around the optical cable 10 for a circle to cut the outer flame-retardant sheath 104 of the optical cable 10 and the internal steel wire 101, and then uses a laser component 4 to irradiate and fuse the remaining part including the optical fiber to achieve a better cutting effect.

[0033] In one embodiment, if Figure 2 As shown, the left clamping assembly 1 and the right clamping assembly 2 of the cutting equipment are arranged on a workbench 5, and the axes of the two are aligned. After the optical cable 10 is clamped, the axis of the optical cable 10 at the clamping position is kept aligned with the axes of the left clamping assembly 1 and the right clamping assembly 2; the electric saw assembly 3 is arranged on the right clamping assembly 2, and is located between the left clamping assembly 1 and the right clamping assembly 2. It can rotate around the axis of the right clamping assembly 2 to perform circular cutting on the optical cable 10, and the cutting depth can also be adjusted to accommodate optical cables 10 of different diameters; the laser assembly 4 is arranged on the electric saw assembly 3, and the light outlet and the slice of the electric saw assembly 3 are kept in the same plane. When emitting light, the laser irradiates the cut portion of the optical cable 10 after being cut by the electric saw assembly, and the remaining portion is laser cut.

[0034] like Figure 2 and Figure 4 As described above, an annular guide groove 22 is provided on the right side surface of the right clamping assembly 2, and the guide groove 22 is arranged around the axis of the right clamping assembly 2 and the axes of the two remain coincident; to facilitate the placement of the optical cable 10 in and out, both the left clamping assembly 1 and the right clamping assembly 2 are provided with an opening for the optical cable 10 to enter and exit, and similarly, the guide groove 22 also avoids the opening, and an open ring 23 is slidably connected in the guide groove 22, and the arc length of the open ring 23 is greater than the arc length of the guide groove 22 at the position where the opening is avoided, so that the open ring 23 can smoothly pass through the opening without falling off. The electric saw assembly 3 is fixedly connected to the open ring 23 and rotates together with the open ring 23.

[0035] In one embodiment, if Figure 2 , Figure 3As shown, the electric saw assembly 3 includes a mounting shell 31, an electric saw body 32 and an adjusting member, wherein the mounting shell 31 is fixedly connected to the open ring 23, the electric saw body 32 is disposed in the mounting shell 32, and can reciprocate toward and away from the axis of the right clamping assembly 2, and the adjusting member is disposed on the mounting shell 31, and can be adjusted to drive the electric saw body 32 to move.

[0036] The adjusting member of the above embodiment preferably adopts a hand screw 100, which is threadedly connected to the mounting shell 31, and the tail of the hand screw 100 is movably connected to the tail of the electric saw body 32. By manually turning the hand screw 100, the electric saw body 32 can be driven to move, thereby adjusting the cutting depth of the electric saw body 32. Of course, the adjusting member can adopt an electric push rod, in conjunction with necessary programs, to achieve automatic adjustment of the cutting depth.

[0037] Since the electric saw body 32 generates heat when working, in order to improve the heat dissipation efficiency, a cooling fan 33 is arranged on the mounting shell 31 to blow the external cold air into the mounting shell 31. At the same time, an air outlet duct 34 is arranged on the other side of the mounting shell 31. The end of the air outlet duct 34 is directed toward the saw blade 321 of the electric saw body 32, so that the wind coming out of the mounting shell 31 is blown toward the cutting position, and the cut debris is blown away, which is beneficial to the irradiation and cutting of the laser component 4, reduces the melting and accumulation of debris, and further improves the cutting effect.

[0038] In one embodiment, if Figure 4 and Figure 5 As shown, the electric saw assembly 3 includes a mounting plate 36 extending from one side, and the laser assembly 4 is mounted on the mounting plate 36. Preferably, the laser assembly 4 includes a laser 41 and a pusher 42, wherein the laser 41 is swingably connected to the mounting plate 36, and the pusher 42 is arranged on the mounting plate 36 behind the laser 41, and the output end of the pusher 42 is connected to the tail of the laser 41, and is used to push the laser 41 toward the axis direction of the right clamping assembly 2 to make a swinging motion while approaching, when the light emitted by the laser 41 can sweep over the remaining part of the optical cable after being cut by the electric saw body 32, and can also drive the laser 41 to reset, that is, away from the axis of the right clamping assembly 2.

[0039] like Figure 5As shown, the mounting plate 36 is provided with two limit blocks, namely the first limit block 361 and the second limit block 362, and the top of the limit block is provided with a bending portion, which is used to block and limit the laser 41 in the direction perpendicular to the mounting plate 36. The mounting plate 36 is provided with two grooves, namely the first groove 363 and the second groove 364, wherein the first groove 363 faces the axis of the right clamping assembly 2, and the second groove 364 is closer to the axis of the right clamping assembly 2 relative to the first groove 363 and is arranged obliquely. The bottom of the laser 41 is provided with two short cylinders, namely the first short cylinder 411 and the second short cylinder 412, which are respectively fitted in the first groove 363 and the second groove 364 and are limited by them. In this way, when the pusher 42 pushes the laser 41 to move, the first groove 363 and the second groove 364 have a limiting effect, so that the second short cylinder 412 swings relative to the first short cylinder 411 as the center.

[0040] In one embodiment, if Figure 2 and Figure 3 As shown, the left clamping assembly 1 comprises a left fixed shell 11 arranged on the workbench 5, a clamping member 12 for clamping the optical cable and a plurality of elastic members 13, wherein the clamping member 12 is movably connected in the left fixed shell 11. The plurality of elastic members 13 are evenly arranged in the left fixed shell 11 and abut against the left side of the clamping member 12. The elastic members 13 are preferably springs and there are at least three of them. Due to the elastic force of the elastic members 13, the clamping member 12 is usually pressed against the right inner wall of the left fixed shell 11. When the clamping member 12 is pressed against the right inner wall of the left fixed shell 11, its axis will coincide with the axis of the left fixed shell 11 and the axis of the right clamping assembly 2. Since the outer contour edge of the clamping member 12 is provided with a rounded corner, when a certain point on the right side is acted upon by an external force, the point will shrink inward, and the entire clamping member 12 will be in an inclined state in the left fixed shell 11, and its axis will also form a certain angle with the axis of the clamping assembly 2.

[0041] In one embodiment, if Figure 2 , Figure 3 and Figure 5 As shown, the clamping member 12 includes a housing 121 and a clamping mechanism disposed in the housing 121. The right side of the housing 121 is provided with a protrusion 1211 that can extend out of the left fixed housing 11. Under the action of the elastic member 13, the protrusion 1211 remains extended out of the left fixed housing 11. Figure 4As shown, a top block 411 is provided on the laser 41, and a slope is provided at one end of the top block 411 close to the axis of the right clamping component 2. When the laser 41 moves close to the axis of the right clamping component 2, the slope will first contact the protrusion 1211, pushing the protrusion 1211 therein to retract on the contact side, so that the clamping member 12 is tilted. At this time, the optical cable clamped by the clamping member 12 will bend at a small angle as the clamping member 12 tilts, so that the cutting gap toward the laser 41 is increased, which is beneficial for the laser 41 to cut it.

[0042] In one embodiment, if Figure 2 and Figure 3 As shown, the right clamping assembly 2 includes a right fixed shell 21, and the right fixed shell 21 is fixedly connected to the workbench 5, and the right clamping assembly 2 also includes a clamping mechanism arranged in the right fixed shell 21, and the clamping structure is the same as the clamping structure of the clamping member 12.

[0043] like Figure 6 As shown, the clamping mechanism includes two V-shaped blocks 60 arranged opposite to each other and movable up and down, and two upper and lower clamping arms 20 that can rotate respectively. The two clamping arms 20 push the two V-shaped blocks 60 to move toward and away from each other when rotating to close and open, and the two clamping arms 20 are supported and maintained in an open state by a torsion spring 30. In addition, it also includes a first push block 40, a second push block 50 and a hand screw 100, wherein one side of the first push block 40 is provided with an upper and lower push portion, and the two push portions respectively abut against the outer sides of the two clamping arms, and the second push block 50 abuts against the other side of the first push block 40 through an inclined surface. The hand screw 100 is threadedly connected to the shell wall, with the head remaining above the shell and the tail movably connected to the second push block 50 in the shell. The second push block 50 is adjusted downward by the hand screw 100 to push the first push block 40 to move toward the axis, thereby pushing the two clamping arms 20 to rotate and close; when the hand screw 100 adjusts the second push block 50 to move upward, under the action of the torsion spring 30, the two clamping arms 20 rotate in the opposite direction to open and push the first push block 40 to move away from the axis. The opening and closing of the two clamping arms 20 are adjusted by the hand screw 100 and the torsion spring 30, so that the two V-shaped blocks 60 can clamp and loosen the optical cable. The pushing mechanism of the clamping member 12 extends out and is retained outside the left fixed shell 11. Specifically, a corresponding retention opening is opened on the left fixed shell 11, and the outer shell 121 is provided with an outer protrusion. The first push block 40, the second push block 50 and the hand screw 100 are arranged on the inner wall of the outer protrusion. The entire outer protrusion extends out from the retention opening, so that the hand screw 100 is outside, which is convenient for manual adjustment. At the same time, the outer protrusion matches the size of the retention opening, and the lower edge of the retention opening can block the outer protrusion to prevent the entire clamping member 12 from rotating around the axis when the hand screw 100 is manually tightened.

[0044] The above embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
