[0020] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installing", "connecting", "linking", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.
[0021] The following is as follows Figures 1 to 3 This invention describes a PC fiber optic polishing and positioning device according to an embodiment of the present invention.
[0022] like Figures 1 to 3 As shown, a PC fiber optic polishing and positioning device according to an embodiment of the present invention includes: Positioning platform 100, with a positioning protrusion 110 at the upper end; The grinding clamping assembly 200 is mounted on the positioning table 100 via a positioning protrusion 110. The grinding clamping assembly 200 includes a clamping table 210, through which the positioning protrusion 110 passes. At least one first groove 211 is provided on the periphery of the clamping table 210. A first pressing block 220 is movably installed in each first groove 211 and a limiting groove 2112 is provided. The first groove 211, the first pressing block 220 and the limiting groove 2112 form a product clamping position A. The connecting component 300 is horizontally inserted through the first pressure block 220 and connected to the clamping table 210.
[0023] When using the device, first loosen the connecting component 300 to create a certain amount of space between the first pressure block 220 and the first groove 211. Then, vertically place the optical fiber to be processed into the product placement position A and ensure that the end face of the optical fiber to be processed is in close contact with the positioning table 100. Then, tighten the connecting component 300 to ensure that the first pressure block 220 and the first groove 211 are tightly connected, thereby fixing the optical fiber to be processed and placing it stably in the product placement position A.
[0024] Understandably, the positioning stage 100 is suitable for using a platform with high flatness, thereby further improving the end face alignment of the optical fiber to be processed.
[0025] It is understandable that the arrangement of at least one first groove 211 and product placement position A enables the device to securely clamp at least two or more optical fibers to be processed for end-face alignment.
[0026] In some specific embodiments of this utility model, the grinding clamping assembly 200 further includes a second pressing block 230 and a connecting member 240. The second pressing block 230 is installed on the upper end of the clamping table 210, the positioning protrusion 110 is fitted with the second pressing block 230, one end of the connecting member 240 is pressed on the upper end surface of the second pressing block 230, and the other end of the connecting member 240 passes through the second pressing block 230 and is connected to the positioning protrusion 110.
[0027] like Figure 2 As shown, in this embodiment, the clamping table 210 can be stably installed on the upper end of the positioning table 100 through the mutual connection of the positioning protrusion 110, the second pressure block 230 and the connector 240. The second pressure block 230 and the positioning protrusion 110 can be connected by bolts. The lower end of the connector 240 has threads and can be connected to the threaded hole (not shown in the figure) provided in the positioning protrusion 110.
[0028] It is understandable that the positioning protrusion 110 can also be threaded to the second pressure block 230 with an external thread structure on its surface. The lower end of the connector 240 is threaded to be threaded to the second pressure block 230, and the bottom surface of the connector 240 can contact the top surface of the positioning protrusion 210 to form a spiral buckle structure, which can tightly fix the clamping table 210 to the upper end of the positioning table 100.
[0029] In some specific embodiments of this utility model, the connecting component 300 includes a bolt 310 and an elastic body 320. A second groove 2111 is provided in the first groove 211, and a third groove 221 is provided in the first pressure block 220. The second groove 2111 and the third groove 221 are arranged opposite to each other. One end of the elastic body 320 is located in the second groove 2111, and the other end of the elastic body 320 is located in the third groove 221. The bolt 310 passes through the first pressure block 220 and the elastic body 320 in sequence and is connected to the clamping table 210.
[0030] like Figures 1 to 3 As shown, in this embodiment, the elastic body 320 is a spring, installed in the rectangular groove formed by the second groove 2111 and the third groove 221. The bolt 310 passes through the first pressure block 220 and the elastic body 320 in sequence. When the bolt 310 is tightened, the bolt 310 can drive the first pressure block 220 to compress the spring and move it closer to the side wall of the first groove 211, making the space of the product mounting position A smaller, thereby stably clamping the optical fiber to be processed. When the bolt 310 is loosened, the bolt 310 can drive the first pressure block 220 to release the spring and move it away from the side wall of the first groove 211, making the space of the product mounting position A larger, thereby allowing the optical fiber to be processed to be placed into the product mounting position A, and then tightened for clamping.
[0031] It is understandable that the second groove 2111 and the third groove 221 are arranged to form a groove for placing the elastomer 320.
[0032] Understandably, the torque of the tightening bolt 310 can be pre-set to prevent damage to the optical fiber to be processed due to excessive tightening. A common method is to use a torque wrench commonly used in existing technologies. The elasticity 320 is also set to prevent the bolt 310 from being tightened too quickly and damaging the optical fiber to be processed, and to provide a certain pre-tightening force.
[0033] In some specific embodiments of this utility model, the clamping table 210 further includes a fourth groove 212 and a fifth groove 213, and the bolt 310 can pass through the fourth groove 212 and the fifth groove 213.
[0034] like Figures 1 to 3As shown, in this embodiment, the fourth groove 212 is a rectangular groove, and the fifth groove 213 is a circular groove. The design of the fourth groove 212 and the fifth groove 213 is, on the one hand, to facilitate the connection when the bolt 310 is a long bolt, and on the other hand, to facilitate processing, so that when machining the slots provided for installing the bolt 310, cutting metal chips can be discharged. Furthermore, the design of the fourth groove 212 and the fifth groove 213 can also improve the structural strength of the clamping platform 210.
[0035] In some specific embodiments of this utility model, a sixth groove 2113 is provided on the left and right sides of the first groove 211, and a limiting protrusion 222 is provided on the left and right sides of the first pressing block 220. The limiting protrusion 222 is movably disposed in the sixth groove 2113.
[0036] like Figure 1 and Figure 3 As shown, in this embodiment, the first groove 211 and the first pressing block 220 are "convex" shaped structures. With the cooperation of the sixth groove 2113 and the limiting protrusion 222, the first pressing block 220 can be prevented from detaching from the first groove 211 even without the restriction of the connecting component 300, thereby reducing the risk of the first pressing block 220 falling off and being lost, and making it more convenient to install the connecting component 300.
[0037] Understandably, under the action of the elastic body 320, even when the bolt 310 is in a loose state, one side of the first pressure block 220 can still maintain close contact with one side of the first groove 211, so that the first pressure block 220 can still be placed relatively stably in the first groove 211.
[0038] In some specific embodiments of this utility model, the limiting groove 2112 adopts a V-shaped groove facing the opening of the first pressing block 220, and two limiting grooves 2112 are provided and symmetrically arranged on both sides of the connecting component 300.
[0039] like Figure 1 and Figure 3 As shown in this embodiment, the two limiting grooves 2112 are symmetrically arranged on both sides of the bolt 310, which can make the optical fiber to be processed more evenly stressed on both sides when it is squeezed, and prevent the situation where one side has reached the expected stress while the other side has not been clamped, or one side has reached the expected stress while the other side is overloaded.
[0040] It is understandable that the V-shaped structure of the limiting groove 2112 can work with the first pressure block 220 to clamp the optical fiber to be processed more stably. Furthermore, the product placement position A can also form various shapes such as rectangular grooves and pentagonal grooves with the first pressure block 220 through the structure of the limiting groove 2112 to meet the clamping requirements. However, it is understandable that the more complex the groove shape, the more complicated the processing will be.
[0041] In some specific embodiments of this utility model, the clamping table 210 is also provided with a plurality of through slots 214 evenly distributed.
[0042] like Figure 1 As shown, in this embodiment, the plurality of through slots 214 are circular through slots. The arrangement of the plurality of through slots 214 can reduce the weight of the clamping platform 210 and further enhance the structural strength of the clamping platform 210.
[0043] It is understandable that the diameter of the outer side of several through slots 214 can be smaller than the diameter of the inner side, so as to avoid the opening being too large and affecting the structural strength of the clamping platform 210.
[0044] In some specific embodiments of this utility model, a rotary bearing platform 400 is also included, and a positioning platform 100 is disposed on the rotating end of the rotary bearing platform 400.
[0045] like Figure 1 As shown, in this embodiment, the positioning stage 100 is set on the rotating end of the slewing bearing stage 400. The positioning stage 100 and the clamping platform 210 can be manually operated to rotate relative to the plane under the drive of the inner ring of the slewing bearing stage 400, thereby facilitating the clamping and installation of multiple optical fibers to be processed.
[0046] It is understandable that the slewing bearing table 400 often uses slewing bearings. Slewing bearings are standard mechanical parts, and their model and size can be adapted to the size and weight of the positioning table 100.
[0047] In some specific embodiments of this utility model, the positioning platform 100 has a disc structure, and the positioning protrusion 110 is located at the geometric center of the positioning platform 100.
[0048] like Figure 1 and Figure 2 As shown, in this embodiment, the design of the positioning protrusion 110 being located at the geometric center of the positioning table 100 enables the grinding clamping assembly 200 connected to the positioning protrusion 110 to also be located at the geometric center of the positioning table 100, making it easier for the positioning table 100 to twist and rotate on the rotary bearing table 400, and making it easier to move from the rotary bearing table 400 to the processing location via the grinding clamping assembly 200.
[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
