Tool for manufacturing intersecting line opening of circular tube

The invention belongs to the technologies of the field of manufacturing of airplane structures, and relates to a tool for manufacturing an intersecting line opening of a circular tube. The tool is characterized by comprising a bracket assembly and a cutter guider assembly; the bracket assembly is composed of two bases (1) with vacuum chucks, two columns (2), a cross beam (3), an indexing base (4), two upper clamping plates (6), two lower clamping plates (7), four semi-circular linings (8) and compression screws (10). The invention provides the tool for manufacturing the intersecting line opening of the circular tube, a fuzzy computing process is eliminated, the manufacturing period is shortened, and the hole-forming efficiency is improved. 本发明属于飞机结构制造领域技术，涉及种圆管相贯线开口制造工装。其特征在于：它包括支架组件和刀具导向器组件；支架组件由2个带真空吸盘的底座(1)、2个立柱(2)、横梁(3)、分度座(4)、2个上夹板(6)、2个下夹板(7)、4个半圆衬套(8)和压紧螺钉(10)组成。本发明提出了种圆管相贯线开口制造工装，省略了繁琐的计算过程，缩短了制造工期，提高了制孔效率。
