Technical Field

[0001] The utility model relates to the technical field of optical fiber preform rods, in particular to a novel optical fiber preform rod calibration device. Background Art

[0002] During the fiber optic preform welding process, the fiber optic preform needs to be accurately clamped on the glass lathe and welded with the fiber optic preform tail tube. The fiber optic preform is large in size, heavy in weight, and long in length. It is not easy to align the center of the fiber optic preform with the center of the glass lathe grip by manpower and experience alone. In addition, the fiber optic preform itself is easily damaged, and improper operation by employees can easily cause scratches. Therefore, a convenient and reliable carrier is needed for calibration and fixation to facilitate employee operation. Utility Model Content

[0003] The utility model aims to provide a novel optical fiber preform rod calibration device to overcome the shortcomings of the prior art.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a new optical fiber preform calibration device, comprising a main frame, a guide rail is arranged on the main frame, a sliding platform is arranged on the guide rail, an adjustment component is arranged on the sliding platform, a carrier component is arranged on the adjustment component, and the carrier component is used to carry the optical fiber preform.

[0007] In the above scheme, the specific principle of the carrier assembly is that the optical fiber preform is placed on the support roller. When the optical fiber preform needs to be pushed into the chuck, it is only necessary to push the optical fiber preform, and the optical fiber preform drives the support roller to rotate, thereby realizing the linear movement of the optical fiber preform. Since the optical fiber preform is a cylindrical rod body, in order to better support the optical fiber preform, the support roller is composed of a pair of symmetrically arranged frustum-shaped support rollers, the two ends of the support roller are higher than the middle, and are symmetrically arranged, so that it is easy to keep the height of the supported side of the optical fiber preform consistent, thereby avoiding the tilting phenomenon caused by the inconsistent height of the two ends of the optical fiber preform.

[0008] As an improvement of the novel optical fiber preform calibration device of the utility model, the supporting roller is made of polytetrafluoroethylene material.

[0009] In the above solution, the surface of the support roller made of polytetrafluoroethylene has good smoothness, which can prevent the support roller from damaging the optical fiber preform when placing the optical fiber preform.

[0011] In the above scheme, the specific principle of the adjustment component is that the rotating disk is partially embedded in the connecting sleeve, and the rotating disk can rotate relative to the connecting sleeve. By rotating the rotating disk, the rotating disk drives the adjusting screw to move up and down along the connecting sleeve in the vertical direction, and the adjusting screw drives the U-shaped support plate to move up and down along the vertical direction, thereby realizing the vertical lifting and lowering of the support roller of the U-shaped support plate and the optical fiber preform, and finally realizing the center alignment between the optical fiber preform and the chuck.

[0012] As an improvement of the novel optical fiber preform calibration device of the utility model, a linear bearing is installed at the part where the slider platform contacts the guide rail, and the linear bearing is slidably connected to the guide rail.

[0013] In the above scheme, in order to enable the sliding platform to slide smoothly along the guide rail, the sliding platform and the guide rail are changed from rigid linear sliding to linear sliding, and linear bearings are added to achieve rolling linear sliding between the linear bearings and the slide rails, thereby reducing the friction between the sliding platform and the guide rail, thereby making it easier to push the sliding platform to slide along the guide rail.

The problem of optical fiber preform being easily damaged when pushed into the chuck due to improper operation by employees is solved; in order to better support the optical fiber preform, the support roller is composed of a pair of symmetrically arranged frustum-shaped support rollers, the two ends of the support rollers are higher than the middle, and are symmetrically arranged, so that it is easy to keep the height of the supported edge of the optical fiber preform consistent, thereby avoiding the tilting phenomenon caused by inconsistent heights at both ends of the optical fiber preform; in order to realize the smooth sliding of the sliding platform along the guide rail, the sliding platform and the guide rail are changed from rigid straight line sliding, and linear bearings are added to realize linear sliding of the linear bearings and the slide rail rolling, thereby reducing the friction between the sliding platform and the guide rail, thereby making it easier to push the sliding platform to slide along the guide rail.

[0022] like Figures 1 to 4 As shown, a novel optical fiber preform calibration device comprises a main frame 1, wherein the main frame 1 is provided with a guide rail 2, wherein the guide rail 2 is provided with a sliding platform 3, wherein the sliding platform 3 is provided with an adjustment component 4, wherein the adjustment component 4 is provided with a carrier component 5, wherein the carrier component 5 is used for carrying the optical fiber preform.

[0025] The specific principle of the carrier assembly 5 is to place the optical fiber preform on the support roller 52. When the optical fiber preform needs to be pushed into the chuck, it is only necessary to push the optical fiber preform, and the optical fiber preform drives the support roller 52 to rotate, thereby realizing the linear movement of the optical fiber preform. Since the optical fiber preform is a cylindrical rod, in order to better support the optical fiber preform, the support roller 52 is composed of a pair of symmetrically arranged frustum-shaped support rollers 52.
