Inward-suction-type milling cutter for efficiently processing honeycomb and composite materials

Abstract

The invention discloses an inward-suction-type milling cutter for high-quality efficient processing of honeycomb and composite materials. The inward-suction-type milling cutter comprises a cutter tooth body, a connection screw, a center cutter handle, an inward-suction lining, an inward-suction guide pipe and a sealing end cover. The cutter tooth body is used for cutting off a workpiece material,cutter teeth are arranged on the outer circle of the cutter tooth body, the front cutter face of the cutter teeth is of a hollowed-out structure, so that chippings and solid particles formed by cutting are sucked and enter a cutter body, and bottom blades are symmetrically polished at the bottom of the cutter tooth body; the connection screw is used for making the cutter tooth body and the centercutter handle fixedly connected; the center cutter handle is used for being installed on a machine tool main shaft; a through hole of the middle of the inward-suction lining and the center cutter handle are cooperatively sealed through bearings to achieve opposite rotation, the inward-suction lining and the end face of the cutter tooth body are in clearance fit, and the chippings are sucked and discharged through a hollow part of the lining; the inward-suction guide pipe is used for making the inward-suction lining and an external air suction device connected and is a channel of discharging the chippings; the sealing end cover and the inward-suction lining are arranged at the two ends of the cutter tooth body respectively, so that the cutter tooth body forms a relatively-closed space.

Description

technical field [0001] The invention relates to the technical fields of cutting processing and cutters, in particular to an internal suction milling cutter for high-quality and efficient processing of honeycomb and composite materials. Background technique [0002] Honeycomb sandwich structure composite material is an important weight-reducing material in the field of aviation and aerospace. Honeycomb material has excellent properties such as light weight, high strength, high temperature resistance, and low dielectric, and has become the preferred core material for aerospace composite structural parts. The processing of honeycomb materials is easy to form broken chips and a large amount of solid particles. The broken chips are difficult to recycle, and the solid particles are easy to cause dust pollution and endanger the health of operators. In addition, debris and solid particles are very easy to adhere to the surface of the tool or enter the contact area between the tool a...
