Description

Technical Field

[0001] This utility model belongs to the field of optical fiber preform technology, and in particular relates to a grinding device for polishing optical fiber preforms. Background Technology

[0002] Optical fiber preforms are the core material for manufacturing optical fibers, and they represent the first step in the optical fiber production process. An optical fiber preform is a special type of glass rod, and its internal structure and composition determine the optical performance and quality of the final optical fiber.

[0003] A rotary optical fiber preform magnetorheological polishing machine (publication number: CN207255836U) includes a magnetic rotating wheel, an electromagnet, a graphite rod, a tensioning wheel, a hollow main shaft, bearings, a bearing housing, and a servo motor. The servo motor drives the magnetic rotating wheel to rotate, which in turn drives the electromagnet to rotate, forming a high-speed rotating magnetic field. This magnetic field acts on the magnetorheological fluid in the quartz glass tube to form a high-speed rotating flexible polishing film. This invention utilizes a high-speed rotating magnetic field and different optical fiber preform holding methods to achieve polishing of the outer circumference and inner hole of the optical fiber preform immersed in the magnetorheological fluid circuit.

[0004] The components in the above application, such as the rotating wheel, electromagnet, graphite rod, tensioning wheel, and hollow spindle, work together to polish the outer circle and inner hole of the optical fiber preform immersed in the magnetorheological fluid circuit. However, they cannot solve the problem of adjusting the height and position of the grinding machine during the grinding process of the optical fiber preform. Therefore, we propose a grinding device for polishing optical fiber preforms. Utility Model Content

[0005] The purpose of this invention is to provide a grinding device for polishing optical fiber preforms, thereby solving the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a grinding device for polishing optical fiber preforms, comprising a placement box, a support rod fixedly connected to the bottom of the placement box, a rotating column rotatably connected to the top of the support rod, and an adjustable grinding device provided at the bottom of the placement box.

[0008] Furthermore, the adjustable grinding device includes a sliding groove located at the bottom of the placement box. A housing is slidably connected to the top of the sliding groove, and a connecting rod is slidably connected to the inner side of the housing. One end of the connecting rod is fixedly connected to a grinding machine, and grinding blades are mounted on the inner side of the grinding machine. The entire adjustable grinding device, through the cooperation of the housing, connecting rod, and grinding machine, allows the grinding machine to move flexibly and adjust its position within the placement box, enabling precise grinding of the object. This structural design makes grinding operations more flexible and efficient, adapting to different grinding needs.

[0009] Furthermore, a spring is fixedly connected to the side of the connecting rod, and a fixing post is fixedly connected to one end of the spring. The combined function of the spring and the fixing post is to provide height adjustment for the grinding device, enabling the grinding machine to perform grinding operations with appropriate pressure and stability, ensuring the accuracy and effect of the grinding process, and reducing instability or damage caused by fluctuations in external forces.

[0010] Furthermore, two holes are provided on the side of the housing. These two holes not only reduce the weight of the equipment and improve ventilation and heat dissipation, but also facilitate the installation of other components, adjustment of equipment performance, and maintenance. The design of these holes makes the grinding device more efficient and easier to operate and maintain.

[0011] Furthermore, the diameter of the hole is larger than the diameter of the fixed column, and the side of the hole lies on the moving trajectory of the fixed column. This ensures the free movement of the fixed column, prevents equipment jamming, increases the system's flexibility, protects components from damage, and may also facilitate ventilation or cleaning functions. This design ensures that the grinding device maintains stable, efficient, and precise operation during operation.

[0012] Furthermore, a fixing device is provided at the bottom of the placement box. This fixing device includes a sliding rail located on the bottom of the placement box. An L-shaped support rod is slidably connected to the top of the sliding rail. A circular sleeve is fixedly connected to one end of the L-shaped support rod. A circular groove is formed on the inner side of the circular sleeve, and a fixing rod is slidably connected to the side of the circular groove. An arc-shaped clamping plate is fixedly connected to one end of the fixing rod. The purpose of the entire design is to provide a stable, adjustable fixing system that protects the items from damage.

[0013] Furthermore, the circular sleeve has two threaded openings on its side. This dual threaded design enhances the sleeve's fixation and stability, providing double safety protection, while also offering greater flexibility and convenience for assembly, disassembly, adjustment, and positioning. This design makes the entire fixing device more reliable and versatile.

[0014] Furthermore, the circumferential surface of the threaded opening is threaded with two screws, and the outer surface of the arc-shaped clamping plate is located on the displacement trajectory of the screws. Through the rotation of the two screws on the threaded opening and the cooperation of the displacement trajectory, the clamping force and position of the arc-shaped clamping plate can be precisely adjusted, ensuring uniform and stable clamping, while enhancing the reliability and durability of the fixing device.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model achieves its purpose through the cooperation of components such as sliding groove, outer shell, spring, fixed column, and connecting rod. The operator moves the outer shell, which slides in the sliding groove to adjust the desired position. Pressing the fixed column compresses the spring, thereby adjusting the height of the grinding machine. Releasing the fixed column causes the spring to push the fixed column out of the hole and fix the connecting rod. Once the connecting rod is fixed, the grinding operation becomes more flexible and efficient, adapting to different grinding needs.

[0017] 2. This utility model achieves this by using components such as a sliding track, an L-shaped support rod, a circular sleeve, a circular groove, and an arc-shaped clamping plate in cooperation. The L-shaped support rod moves along the sliding track, allowing the precast rod to be placed into the circular sleeve. By rotating the screw, the screw pushes the arc-shaped clamping plate downward, which then moves downward through the circular groove via a fixing rod. This clamping and fixing of the precast rod provides a stable, adjustable, and protective system that prevents damage to the object.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The adjustable grinding device 4 includes a sliding groove 41, which is located on the bottom of the placement box 1. A housing 42 is slidably connected to the top of the sliding groove 41, and a connecting rod 43 is slidably connected to the inner side of the housing 42. One end of the connecting rod 43 is fixedly connected to a grinding machine 46, and grinding blades 47 are provided on the inner side of the grinding machine 46. The entire adjustable grinding device 4, through the cooperation of the housing 42, the connecting rod 43, and the grinding machine 46, allows the grinding machine 46 to move flexibly and adjust its position within the placement box 1, enabling precise grinding of the object. This structural design makes the grinding operation more flexible and efficient, adapting to different grinding needs.

[0030] A spring 44 is fixedly connected to the side of the connecting rod 43, and a fixing post 45 is fixedly connected to one end of the spring 44. The combined function of the spring 44 and the fixing post 45 is to provide height adjustment for the grinding device, so that the grinding machine 46 can perform grinding operations with appropriate pressure and stability, ensuring the accuracy and effect of the grinding process, and reducing instability or damage caused by fluctuations in external forces.

[0031] The outer casing 42 has two openings 48 on its side.

[0032] The diameter of the hole 48 is larger than the diameter of the fixed post 45, and the side of the hole 48 lies on the moving trajectory of the fixed post 45. This ensures the free movement of the fixed post 45, prevents equipment jamming, increases the system's flexibility, protects components from damage, and may also facilitate ventilation or cleaning functions. This design ensures that the grinding device maintains stable, efficient, and precise operation during operation.

[0033] A fixing device 5 is provided at the bottom of the placement box 1. The fixing device 5 includes a sliding rail 51, which is located on the bottom of the placement box 1. An L-shaped support rod 52 is slidably connected to the top of the sliding rail 51. A circular sleeve 53 is fixedly connected to one end of the L-shaped support rod 52. A circular groove 54 is formed on the inner side of the circular sleeve 53. A fixing rod 55 is slidably connected to the side of the circular groove 54.

The purpose of the entire design is to provide a stable, adjustable fixing system that protects the items from damage.

[0034] The circular sleeve 53 has two threaded openings 57 on its side. This dual threaded opening design enhances the fixation and stability of the circular sleeve 53, providing double safety protection, while also offering greater flexibility and convenience for assembly, disassembly, adjustment, and positioning. This design makes the entire fixing device 5 more reliable and versatile.

[0035] The circumferential surface of the threaded opening 57 is threaded with two screws 58. The outer surface of the arc-shaped clamping plate 56 is located on the displacement trajectory of the screws 58. By rotating on the threaded opening 57 and cooperating with the displacement trajectory, the two screws 58 can precisely adjust the clamping force and position of the arc-shaped clamping plate 56, ensuring uniform and stable clamping, while enhancing the reliability and durability of the fixing device 5.

[0036] One specific application of this embodiment is as follows: the operator moves the outer casing 42, which slides in the sliding groove 41 to adjust the required position, presses the fixing post 45, and the fixing post 45 compresses the spring 44 to adjust the height of the grinding machine 46 as required. When the fixing post 45 is released, the spring 44 pushes the fixing post 45 out of the hole 48 through its own elasticity to fix the connecting rod 43.

[0037] The L-shaped support rod 52 is moved in the sliding track 51, and the preform is placed into the circular sleeve 53. The screw 58 is rotated, and the screw 58 rotates to push the arc-shaped clamping plate 56 to move downward.
