Description

Technical Field

[0001] The utility model relates to the technical field of core rod production, in particular to a positioning device for core rod production and processing with adjustable clamping accuracy. Background Art

[0002] Core rod production is one of the key steps in manufacturing optical fibers and other similar products. The core rod, also known as the preform, is the raw material of the optical fiber, and its radial refractive index is distributed according to the refractive index requirements of the core layer and the cladding. The process of core rod production usually includes the following steps: Material preparation: Select high-purity raw materials, such as silicon, for melting and purification to obtain the basic material for manufacturing the core rod. Core rod manufacturing: Use specific processes and equipment, such as vapor deposition, sol-gel method, etc., to deposit the required materials layer by layer on the surface of the core rod to form a core layer structure with a specific refractive index distribution. This process requires precise control of the deposition conditions to ensure that the transmission performance of the core rod meets the requirements. Heat treatment: The manufactured core rod is subjected to high-temperature treatment to eliminate internal stress and improve the performance of the material.

[0003] During the production and processing of the core rod, the material needs to be positioned to facilitate subsequent processing. However, we consider that it is not convenient to adjust the clamping size during the processing of the core rod, which greatly reduces the accuracy of subsequent processing and is extremely inconvenient. Therefore, a positioning device for core rod production and processing with adjustable clamping accuracy is urgently needed to solve the above problems. Utility Model Content

[0007] Preferably, one side of the two supporting plates opposite to each other is fixedly connected with a supporting tube, and one of the two supporting tubes passes through one of the supporting plates, and one side of the inner wall of the frame is fixedly connected to the fixing plate.

[0008] Preferably, one end of the bidirectional screw is rotatably connected to the inner wall of the frame through a rotating shaft, and the other end of the bidirectional screw passes through the side wall of the frame through a bearing sleeve.

[0009] Preferably, one side of the two nut seats is fixedly connected with a slider, and the two sliders are slidably connected to the inner wall of the frame through a slide rail.
