Description

Technical Field

[0001] This invention belongs to the field of optical fiber production technology, and in particular relates to a hole cleaning device for double-sided hole preforms and its usage method. Background Technology

[0002] For the production and processing of panda-type polarization-maintaining fiber preforms, after side holes are drilled on both sides of the preform, the entire preform and the hole walls need to be cleaned. After cleaning, stress mother rods are installed in the side holes. The size of the stress mother rod is determined by the diameter of the side holes of the preform. The inner hole of the preform needs to be highly clean to facilitate the installation of the stress mother rod.

[0003] Due to the long length of the precast rod and the special location of the side holes, it is not easy to clean the inner holes of the precast rod compared to the outer wall of the precast rod. Currently, the inner holes of the precast rod are generally flushed with flowing liquid. However, due to the large depth of the inner holes, the unpressurized liquid is not conducive to cleaning the inner wall, especially in areas far from the end of the precast rod. Existing cleaning devices have problems of being difficult to operate and having low efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a hole cleaning device for precast bars with double-sided holes. By designing a novel rod end positioning mechanism and hole wall cleaning mechanism as a cleaning device for the side holes of the precast bars, the inner wall of the hole can be cleaned by physical scraping. The hardness of the soft cleaning ring is much less than that of the precast bar, so it will not damage the quality of the inner wall of the precast bar. At the same time, the arrangement of the rod end positioning mechanism can pressurize the hole wall cleaning mechanism, which can actively and completely cover the inner wall of the hole, greatly improving the cleaning efficiency and making it convenient for operators to operate.
