Abstract
Description
Technical Field
[0001] The present application relates to the field of laser technology, and in particular to a clamping device. Background Art
[0002] Optical fiber includes an end cap and a bare fiber fused to the end cap. Optical fiber has important applications in the field of lasers and is used to couple the laser beam emitted by the pump source of the laser. As the power of the laser increases, the power density on the end face of the end cap also increases, so the cleanliness requirements of the end cap, bare fiber, and the fusion surface between the end cap and the bare fiber are also higher.
[0003] Usually, when using optical fiber, the end cap, bare fiber, and the fusion surface between the end cap and the bare fiber need to be checked for cleanliness. At present, when checking the cleanliness, the end cap is first clamped by a clamping device to check the cleanliness of the end face of the end cap. However, when such a clamping device is clamped on the end cap, it is difficult to check the cleanliness of the bare fiber and the fusion surface between the end cap and the bare fiber because the clamping device blocks the bare fiber, resulting in low efficiency of optical fiber cleanliness inspection and great limitations in use.
[0004] Therefore, the above-mentioned existing clamping device has great limitations when used and cannot adapt to more application scenarios. Utility Model Content

[0038] The embodiment of the present application provides a clamping device for solving the technical problem of large limitations in using the clamping device.
[0039] In the embodiments of the present application, Figure 3As shown, the clamping device includes a base 1, a first clamping seat 2, a first clamping member 3, a second clamping seat 4 and a second clamping member 5. The first clamping seat 2 is arranged on the base 1, and the first clamping member 3 is movably connected to the end of the first clamping seat 2 away from the base 1, and the first clamping member 3 can move away from or approach the first clamping seat 2. The second clamping seat 4 is detachably arranged on the base 1, and the second clamping seat 4 and the first clamping seat 2 are located on the same side of the base 1. The second clamping member 5 is movably connected to the end of the second clamping seat 4 away from the base 1, and the second clamping member 5 can move away from or approach the second clamping seat 4.
[0040] like Figure 1 and Figure 2 As shown, the clamping device can be used to fix the optical fiber 7, and the optical fiber 7 includes a bare fiber 71 and an end cap 72, and the bare fiber 71 and the end cap 72 are fused.
[0041] The first pressing member 3 is movably connected to the end of the first clamping seat 2 away from the base 1, and the first pressing member 3 can move away from or approach the first clamping seat 2. Therefore, when the first pressing member 3 approaches the first clamping seat 2, the first pressing member 3 can press the bare fiber 71 of the optical fiber 7 against the first clamping seat 2 to achieve clamping and fixing of the bare fiber 71. When the first pressing member 3 moves away from the first clamping seat 2, the first pressing member 3 can release the bare fiber 71.
[0042] The second pressing member 5 is movably connected to the end of the second clamping seat 4 away from the base 1, and the second pressing member 5 can move away from or approach the second clamping seat 4. Therefore, when the second pressing member 5 approaches the second clamping seat 4, the second pressing member 5 can press the end cap 72 of the optical fiber 7 against the second clamping seat 4 to achieve clamping and fixing of the end cap 72. When the second pressing member 5 moves away from the second clamping seat 4, the second pressing member 5 can loosen the end cap 72.
[0043] The first clamping member 3 of the embodiment of the present application is movably connected to the first clamping seat 2 so that the bare fiber 71 of the optical fiber 7 is clamped to the first clamping seat 2 through the first clamping member 3; the second clamping member 5 is movably connected to the second clamping seat 4 so that the end cap 72 of the optical fiber 7 is clamped to the second clamping seat 4 through the second clamping member 5, thereby achieving clamping and fixing of the optical fiber 7; when inspecting the optical fiber 7, the clamping device can be stood on its side so that the second clamping seat 4 is located above the first clamping seat 2, so that the user can inspect the end face of the end cap 72 from top to bottom; the first clamping member 3 can also be controlled to move away from the first clamping seat 2 so that the first clamping member 3 releases the bare fiber 71, and then after the second clamping seat 4 is removed from the base 1, the second clamping seat 4 is stood on its side so that the bare fiber 71 is located above the end cap 72, so that the user can inspect the fusion surface of the bare fiber 71 and the end cap 72; since the optical fiber 7 can be inspected more comprehensively by the clamping device, the applicability of the clamping device can be improved.
[0044] In one embodiment, if Figure 1 and Figure 3As shown, the first clamping seat 2 is integrally arranged with the base 1 to facilitate users to use the clamping device.
[0045] In one embodiment, if Figure 1 and Figure 2 As shown, the second clamping seat 4 is spaced apart from the first clamping seat 2 along the first direction. After the first clamping member 3 presses the bare fiber 71 to the first clamping seat 2, and the second clamping member 5 presses the end cap 72 to the second clamping seat 4, the clamping device can be rotated in a direction perpendicular to the plane where the base 1 is located, so that the user can check the bare fiber 71 between the first clamping seat 2 and the second clamping seat 4. This allows the user to fully check the optical fiber 7, thereby improving the applicability of the clamping device.
[0046] In one embodiment, if Figure 1 and Figure 2 As shown, one end of the first clamping member 3 is rotatably disposed on the first clamping seat 2, and one end of the second clamping member 5 is rotatably disposed on the second clamping seat 4. When the user rotates the first clamping member 3 and the second clamping member 5, the bare fiber 71 and the end cap 72 can be clamped or loosened respectively, which has a simple structure and is easy to operate.
[0047] In one embodiment, if Figures 1 to 3 As shown, the rotation centerline of the second pressing member 5 is parallel to the first direction, and the second pressing member 5 is located at one end of the second clamping seat 4 close to or away from the first clamping seat 2. In order to set the position of the second pressing member 5 according to the actual inspection requirements of the optical fiber 7, the second pressing member 5 can be better pressed against the end cap 72, which is convenient for users to inspect the optical fiber 7.
[0048] In one embodiment, at least two positioning columns are disposed on the base 1 , and the positioning columns are symmetrically disposed about the first direction; the bottom of the second clamping seat 4 is provided with positioning holes, and the positioning columns can be correspondingly inserted into the positioning holes.
[0049] When installing the second clamping seat 4 on the base 1, align the positioning hole at the bottom of the second clamping seat 4 with the corresponding positioning column on the base 1, then loosen the second clamping seat 4, let the second clamping seat 4 fall freely and approach the base 1, and then insert the positioning column into the positioning hole, and install the second clamping seat 4 on the base 1. When removing the second clamping seat 4 from the base 1, just lift the second clamping seat 4 from the base 1, so that the positioning column exits the positioning hole, thereby realizing the disassembly and assembly of the second clamping seat 4.
[0050] In this embodiment, when the second clamping member 5 is arranged at one end of the second clamping seat 4 away from the first clamping seat 2, the clamping device can be stood on its side so that the second clamping seat 4 is located above the first clamping seat 2, so that the user can check the end face of the end cap 72 from top to bottom.
[0051] When the second clamping member 5 is arranged at one end of the second clamping seat 4 close to the first clamping seat 2, the clamping device can be rotated in a direction perpendicular to the plane where the base 1 is located, so that the user can check the bare fiber 71 between the first clamping seat 2 and the second clamping seat 4. The setting position of the second clamping member 5 on the second clamping seat 4 relative to the first clamping seat 2 can be adjusted by disassembling the second clamping seat 4, rotating it 180°, and then installing it on the base 1.
[0052] After the first clamping member 3 is rotated to loosen the bare fiber 71, the second clamping seat 4 is removed from the base 1 and the second clamping seat 4 is placed sideways so that the bare fiber 71 is located above the end cap 72, so as to inspect the fusion surface between the bare fiber 71 and the end cap 72. When inspecting the fusion surface between the bare fiber 71 and the end cap 72, the location of the second clamping member 5 on the second clamping seat 4 is not required.
[0053] In one embodiment, the clamping device further includes a first magnetic member and a second magnetic member. The first magnetic member is disposed at an end of the first pressing member 3 and / or the second pressing member 5 away from the rotating end thereof. The second magnetic member is disposed at the first clamping seat 2 and / or the second clamping seat 4, and the first magnetic member can be magnetically attracted when it is close to the corresponding second magnetic member.
[0054] Through the corresponding adsorption of the first magnetic attraction member and the second magnetic attraction member, the first pressing member 3 and / or the second pressing member 5 can conveniently press the corresponding bare fiber 71 or the end cap 72 .
[0055] In this embodiment, the first magnetic attraction member may be a magnet, and the second magnetic attraction member may be a magnetic metal. The first magnetic attraction member may also be a magnetic metal, and the second magnetic attraction member may be a magnet.
[0056] In one embodiment, if Figures 1 to 3 As shown, a first groove 21 is provided on the first clamping seat 2, and a second groove 41 is provided on the second clamping seat 4. The length direction of the first groove 21 and the length direction of the second groove 41 are both parallel to the first direction. Among them, the first direction is parallel to the direction from the first clamping seat 2 to the second clamping seat 4. The first groove 21 is used to place the bare fiber 71, and the second groove 41 is used to place the end cap 72, so that the bare fiber 71 is limited by the groove wall of the first groove 21, and the end cap 72 is limited by the groove wall of the second groove 41. In this way, when the first clamping member 3 and the second clamping member 5 respectively clamp the bare fiber 71 and the end cap 72, the bare fiber 71 and the end cap 72 are prevented from being offset.
[0057] In one embodiment, if Figures 1 to 3As shown, the cross-sectional width of the first groove 21 gradually decreases in the direction toward the groove bottom of the first groove 21, and the cross-sectional width of the second groove 41 gradually decreases in the direction toward the groove bottom of the second groove 41. So that the first groove 21 can more accurately limit the bare fiber 71, and the second groove 41 can more accurately limit the end cap 72. In addition, the first groove 21 and the second groove 41 can also respectively limit the bare fiber 71 and the end cap 72 of different diameters, thereby improving the compatibility of the first groove 21 and the second groove 41 in respectively limiting the bare fiber 71 and the end cap 72.
[0058] In one embodiment, if Figures 1 to 3 As shown, the groove depth of the first groove 21 is less than the groove depth of the second groove 41. Since the diameter of the end cap 72 is greater than the diameter of the bare fiber 71, the groove depth of the first groove 21 is less than the groove depth of the second groove 41, and when the first pressing member 3 presses the bare fiber 71 into the first groove 21 and the second pressing member 5 presses the end cap 72 into the second groove 41, it is convenient to make the optical fiber 7 in a straight state.
[0059] In one embodiment, if Figures 1 to 3 As shown, the clamping device further includes an elastic pad, and both the first pressing member 3 and the second pressing member 5 are provided with a mounting groove 6, the first groove 21 and the second groove 41 are respectively located on the movable path of the mounting groove 6, and the elastic pad is arranged in the mounting groove 6. When the first pressing member 3 presses the bare fiber 71, it is the elastic pad arranged on the first pressing member 3 that squeezes the bare fiber 71; when the second pressing member 5 presses the end cap 72, it is the elastic pad arranged on the second pressing member 5 that squeezes the end cap 72, so the elastic buffering effect of the elastic pad can avoid crushing the bare fiber 71 and the end cap 72.
[0060] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
