Abstract

The invention discloses an automatic spiral hole milling device and a method used for a large workpiece multihole system. The automatic spiral hole milling device comprises an L-shaped support as well as a revolution radius regulating mechanism, a tool rotation speed regulating mechanism and a spiral feeding mechanism which are arranged on the support. The automatic spiral hole milling device disclosed by the invention can be taken as a handheld spiral hole making tool and also can be taken as a terminal executing unit of a robot automatic hole making system, and processing quality and efficiency of the large workpiece multihole system can be greatly improved.

Description

technical field [0001] The invention discloses an automatic helical milling device and method for a porous system of a large workpiece, belonging to the technical field of flexible cutting. [0002] Background technique [0003] With the successful production of the domestically produced regional aircraft ARJ21 and the continuous advancement of the development of the C919, how to improve the quality and efficiency of large-scale frame parts assembly and hole-making has become a research hotspot in the final assembly stage of the aircraft. The robotized automatic hole-making system will be the mainstream of the development of intelligent hole-making for large and super-large aircraft workpieces in the future. However, due to the traditional drilling technology used in this type of hole-making system, the axial force is too large when making holes. Currently, it is only suitable for small-diameter processing occasions, and the drilling process often requires multiple combined...
