Abstract
Description
Technical Field
[0001] This application belongs to the technology of optical module components, and particularly relates to a clamping device for an optical module ferrule seat. Background Art
[0002] The ferrule seat is an important component in optical module TOSA, ROSA, etc. After the formation of the ferrule seat 1 as shown in Figure 1 , it is not only necessary to polish the peripheral side, but also to polish the two end faces. For the processed ferrule seat 1, its large end 12 is used to connect the LD or PD, and the small end 11 is used to connect the fiber optic interface component. Currently, generally, the inner wall is tightened from the large end 12 for clamping to complete the polishing process of the small end 11; after the processing of the small end 11 is completed, the clamping position is changed to clamp the small end 11, and then the large end 12 is processed. Of course, the processing sequence of the two ends can also be reversed. This method has the problem of needing to change the clamping position, which undoubtedly increases the process time and has room for improvement. Utility Model Content

The arc-shaped fitting grooves are used to cooperate with the peripheral side of the small end, and both the large-end clamping groove and the small-end clamping groove are concave triangles or trapezoids;
[0007] A pair of plate walls, respectively arranged at both ends of the clamping plates. The plate walls are rotatably connected to the base through a rotating shaft, and the base is installed on the bottom plate;
[0008] A driving mechanism, arranged on the bottom plate and connected to the rotating shaft, for driving the rotating shaft to rotate. The driving mechanism includes a gear coaxially connected to the rotating shaft of one of the plate walls, a rack meshing with the gear and sliding in the slide rail, and a linear cylinder connected to the rack. The linear cylinder and the slide rail are installed on the bottom plate.
[0009] One of the clamping plates is fixed to the plate wall, and the other clamping plate is slidably fitted in the chute of the plate wall. A lead screw is rotatably arranged in the chute, one end of the lead screw passes through the end of the plate wall and is connected to a motor, and the part of the clamping plate fitted in the chute is sleeved on the lead screw.
[0010] The beneficial effects of the present utility model are as follows:

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will describe the embodiments of the present utility model in detail with reference to the drawings. However, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0017] The embodiment of the present application provides an optical module ferrule holder clamping device for batch-clamping a ferrule holder 1 as shown in Figure 1 so as to facilitate the processing of both end faces thereof. The ferrule holder 1 includes an integrally formed large end 12 and a small end 11, and the outer diameter of the large end 12 is greater than the outer diameter of the small end 11.
[0018] Specifically, as shown in Figures 2 - 3 this embodiment of the clamping device includes a pair of clamping plates 2 with adjustable spacing, a pair of plate walls 3, a bottom plate 51, and a driving mechanism provided on the bottom plate 51.
[0019] As shown in Figure 4As shown, on the opposite side of the clamping plate 2, arc-shaped mating grooves 21 are arranged in an array for mating with the periphery of the small end 11. On one side of each arc-shaped mating groove 21, there is a large-end clamping groove 22 for clamping the large end 12, and on the other side of the arc-shaped mating groove 21, there is a small-end clamping groove 23 for clamping the small end 11. Optionally, both the large-end clamping groove 22 and the small-end clamping groove 23 are concave triangles or trapezoids, so as to facilitate clamping the large end 12 and the small end 11 on the circumferential surface by the inclined two walls.
[0020] When it is applied to clamp the ferrule holder 1, after adjusting the distance between a pair of clamping plates 2 to be larger, the ferrule holder 1 can be set upright in an array manner, with its small end 11 at the bottom as a support, the large end 12 at the top, and placed between the clamping plates 2; the position height is set in advance, and then the distance between the clamping plates 2 is adjusted to be smaller, so that the large-end clamping groove 22 abuts against the periphery of the large end 12 through the inclined side wall, and the small-end clamping groove 23 abuts against the periphery of the small end 11. When abutting, there is still a predetermined gap between the arc-shaped mating groove 21 and the side surface of the small end 11, thus completing batch clamping.
[0021] Then, after one end is processed, the clamping plate 2 is flipped 180° to process the other end. After both ends are processed, the clamping plate 2 is opened, the processed ferrule holder 1 is sent to the next process, and waiting for the clamping of the next batch of ferrule holders 1.
[0022] In order to achieve rotation, optionally, through the following scheme, such as Figures 2 - 3 As shown, a pair of plate walls 3 are respectively arranged at both ends of the clamping plate 2. The plate walls 3 are rotatably connected to the base 5 through a rotating shaft 6, and the base 5 is installed on the bottom plate 51; the driving mechanism is connected to the rotating shaft 6 for driving the rotating shaft 6 to rotate. By driving the rotating shaft 6 to rotate through the driving mechanism, the clamping plate 2 can be driven to rotate by the plate wall 6, so as to achieve flipping.
[0023] Specifically, as an optional way, the driving mechanism includes a gear 71 coaxially connected to the rotating shaft 6 of one of the plate walls 3, a rack 72 meshing with the gear 71 and sliding in the slide rail 73, and a linear cylinder 74 connected to the rack 72. The linear cylinder 74 and the slide rail 73 are installed on the bottom plate 51. By the linear cylinder 74 performing extension and retraction movements, the rack 72 is driven to move along the slide rail 73, so as to drive the meshing gear 71 to rotate, and then drive the coaxially arranged rotating shaft 6 to rotate, so as to achieve the flipping of the plate wall 3 and the clamping plate 2. As Figure 2 As shown, it is the state before flipping, as Figure 3 As shown, it is the state after flipping 180°.
[0024] Optionally, the distance adjustment method of a pair of clamping plates 2 can adopt the following method, such as Figure 2As shown in the figure, one clamping plate 2 is fixed to the plate wall 3, and the other clamping plate 2 is slidably fitted in the chute 31 of the plate wall 3. A lead screw is rotatably arranged in the chute 31. One end of the lead screw passes through the end of the plate wall 3 and is connected to the motor 32. The part of the clamping plate 2 fitted in the chute 31 is arranged through the lead screw. In this way, one clamping plate 2 is fixed, and the other clamping plate 2 is driven by the motor 32 to move axially along the lead screw to achieve pitch adjustment.
[0025] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
