The invention discloses a hole forming terminal for spirally milling a carbon fiber composite material by a robot and a method. The hole forming terminal comprises a conical shell, a revolution shaft, an integrated main shaft unit and a cutter, wherein the integrated main shaft unit comprises a rotary driving mechanism, an eccentric and feeding adjusting mechanism and a cutter connecting mechanism. According to the hole forming terminal, the integrated main shaft unit is used for achieving axial feeding and eccentric adjustment of the spiral hole milling cutter, the system integration degree is effectively improved, meanwhile, the adjustment range and the adjustment capacity of the eccentricity of the cutter are increased, and the machining capacity of the hole forming terminal is further enhanced; the eccentric position of the cutter can be adjusted by utilizing the eccentric and feeding adjusting mechanism, so that the spiral milling of the carbon fiber composite material is realized; and the cutter connecting mechanism can be used for detachably butting and mounting the cutter, so that the cutter is conveniently replaced.
Description
technical field [0001] The invention relates to a hole-making terminal and a method, in particular to a hole-making terminal and a method for spirally milling carbon fiber composite materials by a robot. Background technique [0002] Carbon fiber composites are widely used in the structural parts of modern aircraft due to their excellent mechanical properties. However, due to their unique lamination properties, the processing of connecting holes has always faced the risk of delamination at the outlet, especially when using traditional drilling. In order to reduce the axial force of hole making, a new helical milling technology has become a research hotspot in the aerospace manufacturing industry at home and abroad. [0003] Although the helical milling technology has the technological advantage of small axial force, the tool needs to complete four movements such as eccentric adjustment, rotation, revolution, and axial feed when machining holes, which makes its processing eq...
