Description

Technical Field

[0001] This utility model belongs to the field of Faraday rotators and relates to a fixed tooling for processing Faraday rotators. Background Technology

[0002] Application No. 202020622946.2 discloses a fixture for processing a Faraday rotator, including a clamping base. A placement slot inside the clamping base holds a rotator tube, and a movable horizontal plate adjusts the position of a set of rotators. In this application, the rotator tube is horizontally positioned. However, during installation, permanent magnets, crystals, etc., need to be installed inside the rotator tube. Horizontal positioning of the rotator tube is inconvenient for workers; therefore, a fixture that can be moved to vertically position the rotator tube is required. Utility Model Content

[0003] This invention addresses the problem that horizontally positioned optical rotators are inconvenient for workers to assemble components by providing a fixed fixture for processing Faraday rotators that can vertically position the optical rotator.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a fixed fixture for processing a Faraday rotator, comprising a fixed shaft, a positioning plate connected to the top of the fixed shaft, a ratchet plate connected to the fixed shaft, the ratchet plate being disposed below the positioning plate, a base being disposed between the positioning plate and the ratchet plate, the fixed shaft passing through the middle of the base, four pairs of positioning rods connected above the positioning plate, four rotating seats connected above the base, positioning plates being rotatably connected to the rotating seats, the positioning plates passing through between a pair of positioning rods, a housing connected above the base, a through hole for the rotator tube to pass through being provided in the center of the housing, and a pawl mechanism connected to the side of the housing, the pawl mechanism comprising a pawl.

[0005] Preferably, the four pairs of positioning rods are evenly distributed around the positioning disk.

[0006] Preferably, the positioning plate is vertically arranged.

[0007] Preferably, the pawl mechanism further includes a side plate connected to the housing, a slide rod slidably connected to the side plate, a pawl connected to one end of the slide rod near the ratchet disc, a first baffle connected to the slide rod, the first baffle being disposed between the pawl and the side plate, a spring being disposed between the first baffle and the side plate, the spring being sleeved on the slide rod, and the slide rod also being connected to a second baffle, the second baffle being disposed on the side of the side plate away from the first baffle.

[0008] Preferably, the lower end of the fixed shaft is connected to a U-shaped groove, and a bolt is threaded into the U-shaped groove. One end of the bolt extends into the U-shaped groove and connects to a pressure plate.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] This utility model is easy to use. After inserting the optical tube, rotate the outer shell to clamp the optical tube with four positioning plates. Since the ratchet disc is connected to the pawl, the outer shell cannot be rotated in the opposite direction. Therefore, the optical tube is positioned and will not loosen. When you need to remove the optical tube, pull the slide bar to separate the ratchet disc from the pawl, rotate the outer shell in the opposite direction to release the optical tube with four positioning plates, and then you can take it out.

[0011] This utility model is also provided with a U-shaped groove. The table board enters from the opening of the U-shaped groove. The rotating bolt makes the pressure plate press against the lower table surface of the table board, so that this utility model is positioned at the edge of the table. Therefore, this utility model is easy to fix at the edge of the table and is even more convenient to use. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in order to position the optical rotator 9 in a vertical state, a fixed fixture for processing a Faraday rotator includes a fixed shaft 1, a positioning disk 2 coaxially connected to the top of the fixed shaft 1, and a ratchet disk 3 coaxially connected to the fixed shaft 1. The ratchet disk 3 is located below the positioning disk 2. A base plate 4 is provided between the positioning disk 2 and the ratchet disk 3. The fixed shaft 1 passes through the middle of the base plate 4. Four pairs of positioning rods are connected above the positioning disk 2, with a gap between the two positioning rods. Four rotating seats 6 are connected above the base plate 4. Positioning plates 7 are rotatably connected to the rotating seats 6. Each positioning plate 7 passes through the corresponding pair of positioning rods. When the fixed shaft 1 is stationary and the base plate 4 rotates, the end of the positioning plate 7 away from the rotating seat 6 moves closer to or further away from the center of the positioning disk 2. A housing 8 is connected above the base plate 4. A through hole for the optical rotator 9 to pass through is provided in the center of the housing 8. A pawl mechanism is connected to the side of the housing 8. The pawl mechanism includes a pawl 10 for engaging with the ratchet disk 3.

[0021] The method of using this utility model is as follows: Insert the optical rotating tube 9 through the through hole. After one end of the optical rotating tube 9 contacts the positioning plate 2, keep the pawl and ratchet 3 separate and rotate the base plate 4 so that the end of the positioning plate 7 away from the rotating seat 6 is close to the center of the positioning plate 2, thereby clamping the optical rotating tube 9. Then, the pawl and ratchet 3 are connected, so that the base plate 4 stops rotating. When it is necessary to release the optical rotating tube 9, separate the pawl and ratchet 3 and rotate the ratchet 3 in the opposite direction. The positioning plate 7 will then separate from the optical rotating tube 9.

[0022] Furthermore, four pairs of positioning rods are evenly distributed around the positioning disk 2.

[0023] Furthermore, the positioning plate 7 is set vertically.

[0024] Furthermore, the pawl mechanism also includes a side plate 11 connected to the housing 8. A slide rod 12 is slidably connected to the side plate 11. The end of the slide rod 12 near the ratchet disc 3 is connected to the pawl. A first baffle 13 is connected to the slide rod 12. The first baffle 13 is disposed between the pawl and the side plate 11. A spring 14 is disposed between the first baffle 13 and the side plate 11. The spring 14 is sleeved on the outside of the slide rod 12. The slide rod 12 is also connected to a second baffle 15. The second baffle 15 is disposed on the side of the side plate 11 away from the first baffle 13. The first baffle 13 and the second baffle 15 cannot pass through the side plate 11.

[0025] Specifically, in the pawl mechanism, the spring 14 applies a spring force to the first baffle 13, so that the pawl is connected to the ratchet disc 3. When it is necessary to separate the pawl from the ratchet disc 3, the slide bar 12 is pulled to compress the spring 14, and the pawl is separated from the ratchet disc 3.

[0026] Furthermore, a U-shaped groove 16 is connected to the lower end of the fixed shaft 1, and a bolt 17 is threadedly connected to the U-shaped groove 16. One end of the bolt 17 extends into the U-shaped groove 16 and connects to the pressure plate 18.

[0027] Specifically, the U-shaped groove 16 is used to insert into the edge of the table. The tabletop enters through the opening of the U-shaped groove 16, and the pressure plate 18 is pressed against the lower surface of the tabletop by rotating the bolt 17, so as to quickly fix the present invention to the edge of the table.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
