Description

Technical Field

[0001] This utility model relates to the field of positioning equipment technology, specifically to a positioning device for marking fiber optic rings. Background Technology

[0002] In the production process of fiber optic rings, marking is usually required on the surface of the rings to identify information. Currently, most fiber optic ring fixing devices are fixed clamping structures. When positioning fiber optic rings of different sizes is required, the fixing device needs to be adjusted, and the fiber optic rings also need to be repositioned, resulting in low marking accuracy and low efficiency. Traditional positioning devices are complex in structure and cumbersome in operation, making it difficult to meet the positioning and processing needs of fiber optic rings of different sizes. Therefore, there is an urgent need for a rapid positioning device that can adapt to fiber optic rings of different sizes. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the present invention provides a positioning device for marking optical fiber rings to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A positioning device for marking fiber optic rings is provided, comprising a base, a cylindrical body mounted on the base, a detachable circular positioning platform mounted on the cylindrical body, a vertical recoil rod disposed within the circular positioning platform, the lower end of the recoil rod extending through the bottom of the circular positioning platform and slidably disposed inside the cylindrical body, and a compression spring disposed between the lower end of the recoil rod and the bottom of the cylindrical body; two horizontal slide bars slidably disposed within the circular positioning platform, each with an expansion rod at its closest point; a strip-shaped groove opened at the top of the circular positioning platform, through which both expansion rods pass and protrude upward; the upper end of the recoil rod is connected to the two horizontal slide bars via a transmission mechanism, and the tension of the compression spring drives the two expansion rods to move away from each other.

[0006] Furthermore, the transmission mechanism includes two connecting rods, one end of which is vertically hinged to both sides of the top of the recoil rod, and the other end of each connecting rod is fixedly connected to a sector gear. The bottom of each of the two horizontal slide bars is provided with a transmission rack, and the two transmission racks mesh with the two sector gears respectively.

[0007] Furthermore, the connecting rod includes a first connecting rod and a second connecting rod. One end of the first connecting rod is fixedly connected to one end of the second connecting rod, and the other end of the first connecting rod is vertically hinged to the return rod. The sector gear is fixedly connected to the other end of the second connecting rod, and the first connecting rod and the second connecting rod are at a certain bending angle.

[0008] Furthermore, grooves are provided on both sides of the circular positioning platform, and two horizontal slide bars slide in cooperation with the two grooves respectively.

[0009] Furthermore, a limit ring is provided at the upper end of the cylinder, and a rod seat is provided at the lower end of the recoil rod, with the rod seat slidingly engaging with the inner wall of the cylinder.

[0010] Furthermore, a connecting plate is integrally formed at the upper end of the cylinder, and the connecting plate has holes for avoiding the recoil rod. The connecting plate is fixedly connected to the bottom of the circular positioning platform by connecting bolts.

[0011] Furthermore, the two horizontal sliding bars are set collinearly, and both expansion rods are set vertically.

[0012] Furthermore, the extension direction of the strip groove is parallel to the extension direction of the horizontal slide bar.

[0013] Furthermore, the base has several mounting slots on its circumference to facilitate installation and positioning using mounting bolts.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. When using this solution, the fiber optic ring is tightened by pressing two horizontal sliders and using the tension of the compression spring. It is easy to operate and can be adapted to fiber optic rings of different sizes. At the same time, the expansion forces of the two expansion rods are the same in magnitude and opposite in direction, which makes the repeatability of the fiber optic ring high, which is conducive to the batch processing of fiber optic ring marking and improves processing efficiency.

[0016] 2. This solution uses the tension of a compression spring to provide an upward driving force for the recoil rod. The upward recoil rod, through two connecting rods, can drive two sector gears to deflect to both sides, thereby driving two transmission racks to slide horizontally to both sides, which in turn drives two horizontal sliders to slide horizontally to both sides, causing the two expansion rods to move away from each other. Through the two expansion rods exerting two opposite expansion forces on the inner wall of the fiber optic ring, the fiber optic ring is expanded and positioned on the circular positioning platform.

[0020] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0021] like Figure 1 and Figure 2 As shown, the positioning device for marking fiber optic rings in this scheme includes a base 1, a cylinder 2 on the base 1, a circular positioning platform 3 on the cylinder 2, a vertical recoil rod 4 inside the circular positioning platform 3, the lower end of the recoil rod 4 passing through the bottom of the circular positioning platform 3 and slidingly disposed inside the cylinder 2, and a compression spring 5 between the lower end of the recoil rod 4 and the bottom of the cylinder 2.

[0022] Two horizontal slide bars 6 are slidably arranged inside the circular positioning platform 3. The two horizontal slide bars 6 are arranged collinearly, and each of the two horizontal slide bars 6 has an expansion rod 7 at one end that is close to each other. Both expansion rods 7 are arranged vertically. A strip groove 8 is opened on the top of the circular positioning platform 3, and the extension direction of the strip groove 8 is parallel to the extension direction of the horizontal slide bars 6. Both expansion rods 7 pass through the strip groove 8 and protrude upward. The upper end of the return rod 4 is connected to the two horizontal slide bars 6 through a transmission mechanism.

[0023] In specific implementation, the transmission mechanism includes two connecting rods, namely a first connecting rod 9 and a second connecting rod 10. One end of the first connecting rod 9 is fixedly connected to one end of the second connecting rod 10, and the first connecting rod 9 and the second connecting rod 10 are at a certain bending angle. The other ends of the two first connecting rods 9 are respectively vertically hinged to the two sides of the top of the recoil rod 4. The other ends of the two second connecting rods 10 are fixedly connected to sector gears 11. The bottom of the two horizontal slide bars 6 is provided with transmission racks 12, and the two transmission racks 12 are respectively meshed with the two sector gears 11.

[0024] The positioning principle of this solution will be explained in detail below:

[0025] This design utilizes the tension of the compression spring 5 to provide an upward driving force for the recoil rod 4. The upward-moving recoil rod 4, through two connecting rods, drives two sector gears 11 to deflect to both sides, thereby driving two transmission racks 12 to slide horizontally to both sides. This, in turn, causes two horizontal sliders 6 to slide horizontally to both sides, making the two expansion rods 7 move away from each other. Through the two expansion rods 7 exerting two opposing expansion forces on the inner wall of the fiber optic ring, the fiber optic ring is expanded and positioned on the circular positioning platform 3. Therefore, in use, this design can be easily operated by pressing the two horizontal sliders 6 and using the tension of the compression spring 5 to tighten the fiber optic ring. It is also adaptable to fiber optic rings of different sizes. At the same time, the expansion forces of the two expansion rods 7 are the same in magnitude and opposite in direction, resulting in high repeatability of the fiber optic ring, which is beneficial for the batch processing of fiber optic ring marking and improves processing efficiency.

[0026] In practice, grooves 13 are provided on both sides of the circular positioning platform 3, and two horizontal slide bars 6 are slidably engaged with the two grooves 13 respectively to achieve the sliding limit of the two horizontal slide bars 6.

[0027] In specific implementation, a limit ring 14 is provided at the upper end of the cylinder 2, and a rod seat 15 is provided at the lower end of the recoil rod 4. The rod seat 15 slides with the inner wall of the cylinder 2, so that the recoil rod 4 can move stably up and down. At the same time, the limit ring 14 and the rod seat 15 can limit the stroke of the recoil rod 4.

[0028] In specific implementation, a connecting plate 16 is integrally formed on the upper end of the cylinder 2, and the connecting plate 16 is provided with a hole for avoiding the recoil rod 4. The connecting plate 16 is fixedly connected to the bottom of the circular positioning platform 3 by connecting bolts 17. This arrangement makes the cylinder 2 and the circular positioning platform 3 detachable, so as to facilitate the maintenance and replacement of the compression spring 5. Several mounting grooves 19 are provided on the circumference of the base 1, so as to facilitate the installation and positioning by mounting bolts 18, thereby fixing the base 1.
