Continuous automatic inner-chip removal deep-hole inner-reaming cutter based on spray-absorption mechanism

The invention provides a continuous automatic inner-chip removal deep-hole inner-reaming cutter based on a spray-absorption mechanism, which can realize large-amplitude inner-reaming of ultra-long deep blind and through holes, flexibly form various profiled holes with conical surfaces, spherical surfaces and cylindrical surfaces, and meet the machining requirements for high precision and high efficiency. The continuous automatic inner-chip removal deep-hole inner-reaming cutter is mainly characterized in that an eccentric structure with eccentric quantity is arranged between a rotary cutter bit and a cutter body; a screw pair converts movement of a push-and-pull rod into rotation of the rotary cutter bit, and blades arranged on the rotary cutter bit extend and retract through a cutter holder; and guide strips and damping rods are alternately and uniformly distributed in a square groove of an island-style structure in the cutter body so as to achieve the effects of accurate guidance and good cutting stability.
