Abstract

The invention discloses a spiral milling actuator. The spiral milling actuator is characterized by comprising a base, a cutter, a feeding mechanism arranged on the base and used for driving the cutter to do feeding motion, a swinging mechanism arranged on the feeding mechanism and used for driving the cutter to do arc swinging, an eccentric adjusting mechanism used for controlling the radial offset distance of the cutter and and a rotating shaft driving mechanism; the eccentric adjusting mechanism comprises an inner eccentric sleeve, an inner shaft barrel connected with the inner eccentric sleeve through a sliding connecting piece, an outer eccentric sleeve arranged outside the inner eccentric sleeve and an outer shaft barrel fixed to the outer eccentric sleeve; the axes of the inner contours and the outer contours of the inner eccentric sleeve and the outer eccentric sleeve are designed in an offset mode; and the rotating shaft driving mechanism is used for driving the cutter to rotate and comprises a main shaft sleeve, an electric main shaft, an outer eccentric driving assembly for driving the outer shaft barrel to rotate and an inner eccentric driving assembly for driving the inner shaft barrel to rotate.

Description

technical field [0001] The invention relates to the field of automatic hole making for aircraft digital assembly, in particular to a helical milling actuator. Background technique [0002] With the rapid development of the aviation manufacturing field in the new era, the application of carbon fiber composite materials (CFRP) and metal alloy material laminated structures in the aircraft manufacturing process is increasing. In order to overcome the quality defects caused by traditional drilling, helical milling as a A new hole-making technology came into being. Compared with traditional drilling, it has the advantages of small cutting axial force, convenient chip removal, and low cutting temperature. It can effectively solve the problem of hole-making defects such as CFRP delamination, burrs and tears, and alloy material outlet burrs. Highly valued in the field of aviation manufacturing. [0003] Helical milling technology is a kind of intermittent cutting hole making techno...
