Abstract

An aviation lamination material variable-parameter adaptive hole drilling system is characterized by comprising a, an end executor; b, a force sensor or a current detector; c, an adaptive controller; d, a control unit. An electric spindle transducer of the end executor controls the rotation of an electric spindle. The force sensor or the current detector is arranged on the electric spindle to be used for detecting the axial force or the current of the electric spindle. The adaptive controller communicates with the force sensor or the current detector and the control unit to be used for receiving feedback signals of the force sensor or the current detector to send instructions to the control unit, and the control unit controls the end executor to perform corresponding actions. A drive motor of the end executor comprises an encoder to be used for recognizing and feeding back tool feeding positions, and the adaptive controller communicates with the encoder and the control unit to be used for receiving the feedback signals of the encoder to send instructions to the control unit which controls the end executor to perform corresponding actions.

Description

technical field [0001] The invention is applied to the field of hole making for automatic assembly of aircraft components, and in particular relates to a variable parameter self-adaptive lamination hole making system and method for carbon fiber composite materials and metal materials. Background technique [0002] With the advancement of material science and processing technology, and in order to meet the lightweight and high fatigue life performance requirements of the new generation of advanced aircraft and large civil aircraft structural parts, carbon fiber composites are used as a material with excellent performance in such as aircraft panels, It is widely used in the manufacture of aerospace products such as fuselage sections of large passenger aircraft and engine casings. [0003] After the composite material component is formed, in a large number of occasions, it needs to be stacked with other metal structural parts to make holes to realize the assembly of aircraft co...
