Problems solved by technology

Its disadvantages are: the calculation process of template lofting is cumbersome, the efficiency is low, and the manufacturing period is long
Due to the drawing of the intersecting line of the circular pipe, it is often necessary to reserve a repair margin. After the manual hole is made according to the line, it needs to be repaired several times by experienced technicians, resulting in a long manufacturing period and low hole making efficiency.

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of aircraft structure manufacturing, and relates to a tool for manufacturing an opening of a circular pipe intersecting line. Background technique [0002] The existing intersecting line openings of aircraft welded pipe joints are made by hand. Generally, after the traditional template is used to stake out and mark the lines, the holes are manually made according to the lines. The specific steps are: use CAD software to draw intersecting line graphics, make intersecting line templates according to the drawn graphics, draw lines on the round pipe according to the templates, and manually make holes according to the lines to leave a margin of 2mm to 3mm. When welding pipe joints, The installation requirements can only be met after the intersecting holes need to be trimmed several times. Its disadvantages are: the calculation process of template lofting is cumbersome, the efficiency is low, and the manufacturin...
