Abstract

The invention discloses a helical hole milling device, which comprises a self-rotation system, a revolution system, a feed system and an eccentricity adjustment system. In the self-rotation system, the electric spindle drives the milling cutter to rotate through the collet chuck installed on its output shaft. In the revolution system, the revolution motor drives the inner sleeve to revolve relative to the axis of the outer sleeve through the small synchronous pulley, the synchronous belt and the large synchronous pulley. In the feed system, the feed motor drives the feed screw to move the feed nut to realize the feed. The eccentricity adjustment mechanism in the eccentricity adjustment system controls the movement of the offset slider, the fixed anti-backlash nut and the movable anti-backlash nut eliminate the backlash of the eccentricity adjustment system, thereby realizing high-precision adjustment of the eccentricity, installed on the inner sleeve The tightening mechanism on the top realizes tightening the offset slider on the inner sleeve after the adjustment of the eccentricity is completed. The invention can be applied to the integrated, high-quality and high-efficiency hole making of difficult-to-machine materials in the field of aerospace.

Description

technical field [0001] The invention relates to the field of helical milling hole devices, which can be applied to the integrated, high-quality and high-efficiency hole making of difficult-to-machine materials in the aerospace field. Background technique [0002] At present, my country is in a period of rapid development of manufacturing technology, and cutting processing is the main basic process of manufacturing technology. As an important part of the manufacturing industry, aerospace has always been the industry with the richest high-tech. In aviation manufacturing, assembly hole making is a key link in the manufacture and assembly of aircraft and large aircraft. The hole making efficiency directly restricts the aircraft assembly cycle, and the hole making quality will also directly affect the fatigue resistance of the connected structural parts. The traditional drilling process is a continuous cutting process. For titanium alloys with poor thermal conductivity, the dril...
