Hollow automatic rotating clamping chuck

Abstract

The invention relates to a hollow automatic rotary clamping chuck, comprising a base, a hollow rotating shaft and a clamping chuck connected with the hollow rotating shaft; wherein the hollow rotatingshaft is installed at the front end of the base through a bearing and connected with a rotating driving mechanism through a transmission device, the lower end of the hollow rotating shaft is connected with the clamping chuck, and the clamping chuck is an automatic clamping chuck. According to the invention, tasks of automatically clamping and loosening the optical fiber preform can be completed,the use and operation are convenient, and the working efficiency is high; the clamping device is reasonable and compact in structural arrangement, high in automation degree, constant in clamping tightness, good in safety and high in clamping reliability. The clamping chuck can be used for clamping various optical fiber preforms with different diameters, and particularly can be used for clamping large-size optical fiber preforms with the diameters of 120 mm or above, so that the clamping chuck fully satisfies the requirements of large-size, large-scale, automatic, efficient and safe optical fiber manufacturing and production.

Description

Technical field [0001] The invention relates to a hollow automatic rotating clamping chuck, which is used for clamping and rotating an optical fiber preform, and belongs to the technical field of optical fiber preform processing equipment. [0002] technical background [0003] In recent years, with the continuous development of communication technologies 4G and 5G, Internet access speeds worldwide have increased, and the demand for 4G and 5G has increased. The upgrading of the communication bandwidth of each backbone has accelerated, and the optical fiber and cable industry has developed rapidly. The manufacturing size is getting larger and larger, and the efficiency requirements for the processing and testing of optical fiber preforms are also getting higher and higher. [0004] In the processing and inspection procedures of optical fiber preforms, it is often necessary to clamp and rotate the optical fiber preforms (or core rods) continuously or intermittently. Most of the existin...

Problems solved by technology

[0004] In the processing and testing process of optical fiber preform, it is often necessary to clamp and rotate the optical fiber preform (or core rod) continuously or intermittently. Most of the existing optical fiber preform rotary clamping chucks need to be manually operated. Elasticity and loading and unloading of prefabricated rods not only have high operating intensity and potential safety hazards, but also have low operating efficiency and different clamping degrees. With the continuous increase of the diameter and length of optical fiber preformed rods, the above situation becomes more prominent
