Description

Technical Field

[0001] The utility model belongs to the technical field of preformed rod processing, in particular to a displacement device for punching holes in preformed rods. Background Art

[0002] For the production of special polarization-maintaining optical fibers, such as panda-type polarization-maintaining optical fibers, it is necessary to open double symmetrical holes on the preform rod, and then embed stress mother rods of corresponding sizes in the double symmetrical holes. However, since the quartz mother rod is made of a relatively hard material, it is necessary to select a diamond drill bit and use mechanical drilling to open the symmetrical holes.

[0003] Regarding the mechanical drilling on the preform rod, since the preform rod is too long, the corresponding drill rod is too long. As the drilling depth increases, the stability of the drill rod and the drill bit is difficult to guarantee. The transmission of force affects the drilling accuracy and efficiency, and the straightness of the drilling cannot be effectively ensured, affecting the symmetry and accuracy of the holes on the preform rod, thereby affecting the subsequent assembly of the mother rod and the quality of the finished product.

[0004] Similarly, the existing drilling machine tool can only drill a hole in a single preform rod, and a new workpiece can be processed only after the drilling is completed. It is impossible to process quickly and continuously, and the work efficiency is too low, which affects the work efficiency.

[0005] Therefore, designing a new tool to achieve highly stable, continuous and efficient punching is a problem that needs to be solved by workers in this field. Utility Model Content
