Description

Technical Field

[0001] The utility model relates to the technical field of rod centering drilling fixtures, in particular to a continuous core rod drilling tool. Background Art

[0002] When processing hole structures in existing pipe fittings, punching or drilling is usually used. The drilling method is generally to use a drilling head to drill holes in the position to be processed in the pipe fitting. In particular, in ordinary processing, the inner hole is directly opened on a lathe. After completing the processing of a single workpiece, complicated disassembly and assembly operations are required to replace the workpiece to be processed. The process is cumbersome, time-consuming, and inefficient. In addition, the clamping point of the reinstalled workpiece is prone to deviation, resulting in errors in the actual drilling parameters, resulting in inconsistent hole parameters, affecting the accuracy and consistency of the core rod drilling process.

[0003] In addition, although the prior art begins to load materials by placing the core rod on a multi-station turntable so that the tooling can continuously perform batch drilling processing, the existing turntable structure can only vertically limit the core rod of a single specific size, and usually can only limit and fix the lower half of the core rod. When the drill bit starts drilling from the axial upper end face of the core rod, since there is no effective clamping and positioning of the upper section of the core rod, it is very easy for the upper section of the core rod to shake or shift slightly as the drill bit drills, resulting in the center hole formed by the drilling process shifting or expanding, greatly reducing the quality and accuracy of the drilling. At the same time, the existing drill disc structure cannot fix core rods of different diameters. When processing core rods of different sizes, the clamping turntable structure needs to be replaced, which greatly reduces the processing efficiency and increases the production cost, and does not have high adaptability.
