Description

Technical Field

[0001] The present application belongs to the field of tooling devices, and in particular, relates to a fastening tooling device and a stripping device. Background Art

[0002] Optical fiber is a cylindrical dielectric waveguide consisting of three parts: core, cladding, and coating. The core diameter of ordinary single-mode and few-mode optical fibers is generally about 8 to 20um, and the cladding diameter is 125um. When processing optical fibers, the coating is generally stripped off the part to be processed, and the optical fiber clamp clamps the cladding part of the optical fiber. In the current process of making glass tube devices, employees must first pass the engraved optical fiber through the glass tube, stop at the appropriate position, and fix the two ends of the optical fiber on the optical fiber clamps on both sides, and then inject glue into both ends of the glass tube and solidify it. In this process, the optical fiber in the production process needs to be as centered and straight as possible in the glass tube. However, since the glass tube is prone to rolling on a plane, this can easily lead to the risk of damage or even breakage of the optical fiber. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0028] The embodiments of the present application provide a fastening tooling device and a laser welding system to solve the problem that the existing pipeline workpiece cannot be positioned during the assembly process with the fiber core, resulting in damage to the optical fiber. The following will be described in conjunction with the accompanying drawings.

[0029] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, Figure 1 A three-dimensional schematic diagram of a first form of a fastening tooling device provided in an embodiment of the present application, Figure 2 A perspective schematic diagram of a second form of a fastening tooling device provided in an embodiment of the present application, Figure 3 This is a first assembly structure diagram of the fastening fixture device and the pipeline workpiece 5 provided in an embodiment of the present application. Figure 4 The second assembly structure diagram of the fastening fixture device and the pipeline workpiece 5 provided in the embodiment of the present application. The embodiment of the present application provides a fastening fixture device, including a limit base 1, a limit gland 2 and a limit protection member 3, wherein the material of the limit protection member 3 is a soft material. For example, the limit protection member 3 can be made of a silicone material, or the limit protection member 3 can also be made of a rubber material, or the limit protection member 3 can be made of a foam material.

[0030] In this embodiment, Figures 1 to 4 As shown, the longer side of the limit base 1 is defined as the long side of the limit base 1, and the long side of the limit base 1 is the length direction L of the limit base 1. The limit base 1 is provided with a clamping station slot 13, which is extended along the length direction L of the limit base 1, and in the length direction L of the limit base 1, the two opposite sides of the clamping station slot 13 penetrate the limit base 1 to form a station slot opening, and the clamping station slot 13 has a first limit wall 11 and a second limit wall 12 that are arranged oppositely. The bottom surface of the base used to abut against the installation base surface in the device in the limit base 1 is further defined, and the direction perpendicular to the bottom surface of the base is the height direction of the limit base 1, the groove depth direction of the clamping station slot 13 is consistent with the height direction of the limit base 1, and the clamping station slot 13 penetrates the limit base 1 in the height direction of the limit base 1 to form a station opening.

[0031] Exemplary, please Figures 1 to 4 As shown, the first limiting wall 11 and the second limiting wall 12 of the clamping station slot 13 extend from the side of the station opening along the first direction inclined to the middle part of the clamping station slot 13, and the first direction is inclined to the groove depth direction of the clamping station slot 13, so the cross section of the clamping station slot 13 can be a V-shaped groove or an inverted trapezoidal groove. When the pipeline workpiece 5 is placed in the clamping station slot 13, the side wall of the pipeline workpiece 5 will abut against the first limiting wall 11 and the second limiting wall 12 of the clamping station slot 13 under the action of its own gravity, thereby achieving the purpose of rapid self-positioning of the pipeline workpiece 5 in the clamping station slot 13.

[0032] In addition, constrained by the clamping station slot 13, the pipeline workpiece 5 will not be able to deflect along its circumferential direction, thereby ensuring that the pipeline workpiece 5 is stationary relative to the limiting base 1, and will not roll, thereby posing a risk of damaging the fragile optical fiber to the pipeline workpiece 5. At the same time, with the cooperation of the first limiting wall 11 and the second limiting wall 12 arranged relatively, the pipeline workpiece 5 can also be accurately positioned, which is conducive to the optical fiber passing through and fixing the center of the pipeline workpiece 5. After the assembly and fixation are completed, the two ends of the pipeline workpiece 5 extend from the station slot of the clamping station slot 13, thereby facilitating the picking and placement of the pipeline workpiece 5.

[0033] For further details, please refer to Figures 1 to 4 As shown, the limiting gland 2 is provided with an embedding groove 21, and the groove length direction of the embedding groove 21 is preferably consistent with the groove length direction of the clamping station groove 13, and the embedding groove 21 passes through the limiting gland 2 along its groove length direction to form two oppositely arranged embedding groove 21 openings. The limiting gland 2 is provided with a gland fitting surface for abutting the limiting base 1, and the vertical direction perpendicular to the gland fitting surface is the thickness direction of the limiting gland 2. The groove depth direction of the embedding groove 21 is consistent with the thickness direction of the limiting gland 2, and in the thickness direction of the limiting gland 2, the embedding groove 21 is provided with an embedding opening, that is, the embedding groove 21 passes through the limiting gland 2 in the thickness direction of the limiting gland 2 to form an embedding opening. The above-mentioned limit protection piece 3 is embedded in the embedding groove 21, and the limit protection piece 3 is embedded in the embedding groove 21 from the embedding opening of the embedding groove 21. Optionally, the side of the limit protection piece 3 close to the mouth of the embedding groove 21 can extend out of the mouth of the embedding groove 21. Optionally, the side of the limit protection piece 3 close to the mouth of the embedding groove 21 can be consistent with the mouth of the embedding groove 21.

[0034] Exemplarily, a side of the above-mentioned limiting protection member 3 close to the embedding opening is flush with the embedding opening of the embedding groove 21 .

[0035] In this embodiment, when the limiting gland 2 covers the limiting base 1, the limiting protection member 3 can cooperate with the first limiting wall 11 and the second limiting wall 12 of the clamping station slot 13 to perform three-point positioning of the pipeline workpiece 5 in the assembly station slot. That is, the limiting gland 2 covers the limiting base 1 until it abuts against the limiting gland 2, and the limiting protection member 3 abuts against the side wall of the pipeline workpiece 5 and deforms, which not only avoids the problem of the pipeline workpiece 5 being damaged due to the rigid contact between the pipeline workpiece 5 and the limiting gland 2, but also ensures that the pipeline workpiece 5 abuts more firmly in the assembly station slot, and under the action of the limiting protection member 3, the pipeline workpiece 5 is not easy to deflect around its central axis.

[0036] In addition, embedding the position-limiting protection member 3 in the embedding groove 21 not only facilitates the rapid disassembly, assembly and replacement of the position-limiting protection member 3, but also ensures that the position-limiting protection member 3 can completely cover the pipeline workpiece 5 and abut against the pipeline workpiece 5 when the position-limiting gland 2 covers the position-limiting base 1, thereby ensuring the stable assembly of the pipeline workpiece 5. At the same time, since the embedding groove 21 can also provide a certain deformation space, the problem that the position-limiting gland 2 cannot be completely covered due to insufficient space provided in the assembly station groove is avoided.

[0037] It is understandable that the material of the above-mentioned pipeline workpiece 5 is generally silicon dioxide or quartz, and its refractive index is generally 1.45, so the pipeline workpiece 5 is a transparent structural member. The above-mentioned limit base 1 is made of 6061 aluminum alloy material, which is moderately soft and hard and wear-resistant.

[0038] Please combine the specific Figures 1 to 4 As shown, the limiting protection member 3 at least covers part of the clamping station slot 13 in the slot length direction of the clamping station slot 13. For example, if the long side dimension of the limiting base 1 is smaller than the dimension of the limiting gland 2 in the length direction L, the slot length dimension of the clamping station slot 13 is larger than the slot length dimension of the embedded slot 21, so that the length dimension of the limiting protection member 3 embedded in the embedded slot 21 is smaller than the slot length dimension of the clamping station slot 13. The limiting gland 2 preferably covers the middle part of the limiting base 1 to ensure that the limiting protection member 3 abuts against the position of the pipeline workpiece 5, so that the force of the limiting protection member 3 is more uniform.

[0039] In this embodiment, please refer to Figure 2 As shown, along the slot width direction of the clamping station slot 13, the width dimension of the limiting protection member 3 is equal to the slot width dimension of the clamping station slot 13, that is, the slot width dimension of the embedding slot 21 is equal to the slot width dimension of the clamping station slot 13, and when the limiting pressure cover 2 is covered on the limiting base 1, in the width direction of the clamping station slot 13, the clamping station slot 13 is located within the coverage range of the limiting protection member 3, thereby avoiding the risk of the side edge of the embedding slot 21 close to the embedding opening side abutting against the pipeline workpiece 5, thereby protecting the pipeline workpiece 5 from damage.

[0040] In other embodiments, along the slot width direction of the clamping station slot 13, the width dimension of the position-limiting protection member 3 is greater than the slot width dimension of the clamping station slot 13, that is, the slot width dimension of the embedded slot 21 is greater than the slot width dimension of the clamping station slot 13, and the edge of the position-limiting protection member 3 close to the station opening of the clamping station slot 13 will abut against the position-limiting base 1, so that the position-limiting protection member 3 can be more stable when deformed, and will not be excessively deformed due to extrusion. At the same time, it can also ensure that the position-limiting protection member 3 is more stably assembled in the embedded slot 21.

[0041] In order to ensure that the limit protection member 3 can be firmly assembled in the embedded groove 21, the above-mentioned limit protection member 3 can be optionally connected to the embedded groove 21 by gluing. That is, an adhesive (such as structural adhesive, etc.) or tape (such as double-sided tape) is adhered to the inner side wall of the embedded groove 21, so that the limit protection member 3 can be bonded and fixed to the side wall of the embedded groove 21, thereby ensuring the stability of the assembly between the limit protection member 3 and the limit pressure cover 2. It can also be selected that the limit protection member 3 is connected to the embedded groove 21 by a Velcro tape, which can not only achieve the purpose of more stable assembly between the limit protection member 3 and the limit pressure cover 2, but also achieve the convenience and efficiency of replacing the limit protection member 3.

[0042] Based on the above implementation methods, please refer to Figure 1 , Figure 2 and Figure 3 As shown, the first limiting wall 11 and the second limiting wall 12 are both provided with an anti-scratch protection part 14 on the side of the notch near the clamping station slot 13. The anti-scratch protection part 14 here can be a chamfered structure or a rounded structure, or the anti-scratch protection part 14 can be a strip structure made of soft material, and the anti-scratch protection part 14 extends along the slot length direction of the clamping station slot 13. In this way, during the process of placing and fixing the pipeline workpiece 5 in the clamping station slot 13 or taking the pipeline workpiece 5 out of the clamping station slot 13, the pipeline workpiece 5 will not have the risk of scratching and damaging the edge position of the first limiting wall 11 and the second limiting wall 12 on the side of the notch near the clamping station slot 13, ensuring that the pipeline workpiece 5 is not damaged during the disassembly process, thereby further improving the safety of production.

[0043] It can be understood that, in addition to the above-mentioned manner that the anti-scratch protection part 14 is provided on the side of the notch of the first limiting wall 11 and the second limiting wall 12 close to the clamping station slot 13, one of the first limiting wall 11 and the second limiting wall 12 can also be provided with an anti-scratch protection part 14. In addition, the anti-scratch protection part 14 provided on the side of the notch of the first limiting wall 11 and the second limiting wall 12 close to the clamping station slot 13 can also be provided with different structures, for example, one of the first limiting wall 11 and the second limiting wall 12 is provided with an anti-scratch protection part 14 of a chamfered structure, and the other of the first limiting wall 11 and the second limiting wall 12 is provided with a rounded structure.

[0044] On the basis of the above-mentioned embodiment, the first limiting wall 11 and the second limiting wall 12 are both provided with an elastic protective layer, and the elastic protective layer here can be selected as a silicone layer, a rubber layer, or a plastic layer. The elastic protective layer extends along the groove length direction of the clamping station groove 13 to ensure that an elastic protective layer is disposed between the pipeline workpiece 5 and the clamping station groove 13, thereby ensuring that no rigid contact is formed between each part of the pipeline workpiece 5 and the clamping station groove 13, thereby avoiding the risk of damage to the pipeline workpiece 5 due to extrusion. In addition, under the action of the elastic protective layer, the friction resistance between the pipeline workpiece 5 and the first limiting wall 11 and between the pipeline workpiece 5 and the second limiting wall 12 is increased, thereby better avoiding the pipeline workpiece 5 from rotating around its central axis.

[0045] It can be understood that the elastic protective layer at least covers a portion of the first limiting wall 11, and the elastic protective layer at least covers a portion of the second limiting wall 12. In addition, in addition to the above-mentioned manner in which both the first limiting wall 11 and the second limiting wall 12 are provided with an elastic protective layer, it is also possible to provide one of the first limiting wall 11 and the second limiting wall 12 with an elastic protective layer, or the elastic protective layers provided on the first limiting wall 11 and the second limiting wall 12 can also be made of different materials.

[0046] In some embodiments, please refer to Figures 1 to 5 As shown, the fastening tooling device also includes a first magnetic component 41 and a second magnetic component 42. The limiting cover 2 is provided with a first assembly groove 15 in which the first magnetic component 41 is embedded, and the limiting base 1 is provided with a second assembly groove 16 in which the second magnetic component 42 is embedded. Among them, the shape and size of the first assembly groove 15 are adapted to the shape and size of the first magnetic component 41, and the height dimension of the first magnetic component 41 is less than or equal to the groove depth dimension of the first assembly groove 15, so that the first magnetic component 41 will not protrude from the first assembly groove 15. Similarly, the shape and size of the second assembly groove 16 are adapted to the shape and size of the second magnetic component 42, and the height dimension of the second magnetic component 42 is less than or equal to the groove depth dimension of the second assembly groove 16, so that the second magnetic component 42 will not protrude from the second assembly groove 16.

[0047] Such arrangement can not only effectively ensure that the limit gland 2 is firmly installed on the limit base 1, so that the limit protection member 3 can be firmly abutted against the pipe workpiece 5, but also effectively disassemble and install the pipe workpiece 5 into the clamping position groove 13 of the limit base 1. At the same time, it can also ensure that the limit protection member 3 can completely cover the pipe workpiece 5 and abut against the pipe workpiece 5 when the limit gland 2 covers the limit base 1.

[0048] It can be understood that the number of the first magnetic member 41 can be selected as one, the first magnetic member 41 is extended along the length direction of the limit gland 2, and the second magnetic member 42 is correspondingly configured as one. The number of the first magnetic member 41 can also be selected as multiple, multiple first magnetic members 41 are evenly arranged and distributed along the length direction of the limit gland 2, the number of the second magnetic members 42 is the same as the number of the first magnetic members 41, and each first magnetic member 41 is correspondingly arranged with each second magnetic member 42.

[0049] In order to further improve the efficiency and convenience of disassembly and assembly, based on the above implementation method, please combine Figures 1 to 5 As shown, the limiting base 1 also has a first hinged portion 17, and the first hinged portion 17 is arranged on one side of the clamping station slot 13 along the length direction of the slot. The limiting pressure cover 2 has a second hinged portion 22, and the second hinged portion 22 is hingedly connected to the first hinged portion 17. When the limiting pressure cover 2 is closed, the first magnetic part 41 will be able to be quickly and accurately attracted to the second magnetic part 42.

[0050] Based on the structure and connection relationship of the above-mentioned fastening fixture device, the embodiment of the present application also provides a stripping device, including the above-mentioned fastening fixture device. When using the stripping device, first place and fix the pipeline workpiece 5 in the clamping station slot 13 of the fastening fixture device, and cover the limiting pressure cover 2 until the first magnetic part 41 magnetically attracts the second magnetic part 42, so that the limiting pressure cover 2 abuts against the limiting base 1. At this time, the pipeline workpiece 5 is firmly installed on the fastening fixture device. Then, the engraved fiber core directly passes through the pipeline workpiece 5, and the two ends of the fiber core are fixed on the optical fiber clamps on both sides of the stripping device, and then glue is injected into the interior of the pipeline workpiece 5 and cured. After the curing is completed, open the limiting pressure cover 2 and the optical fiber clamps on both sides, and the pipeline workpiece 5 can be taken out and removed. The operation is simple and efficient, and it effectively improves the safety and job yield of the optical fiber during the operation.
