Diamond sleeve grinding cutter suitable for drill sleeve guide

Abstract

A diamond sleeve grinding cutter suitable for drill sleeve guide comprises a circular drill rod and a guide drill sleeve. The guide drill sleeve is positioned on the middle lower portion of the drill rod and connected with a drill template, the drill rod comprises a threaded handle (1), a 120-degree positioning conical surface (2), a core discharging port (3), a core discharging guide hole (4), a dust chip discharging spiral groove (6), a spiral guide surface (7), a dust chip discharging straight groove (8) and a cutter cutting edge (9) from top to bottom, double cylindrical surfaces are combined to from the guide drill sleeve, and a through hole is formed in a core, so that the drill rod conveniently penetrates the through hole. The diamond sleeve grinding cutter is an integrated cutter, the quality of a machined hole is fine, defects are fewer, hole forming efficiency is high, a composite hole with a large diameter can be machined once, dust cuttings are fewer and almost discharged in the form of material cores, environmental pollution is low, and materials can be repeatedly used.

Description

Technical field: [0001] The invention relates to a hole-making tool for composite material processing, in particular to a diamond sleeve grinding tool suitable for drill sleeve guidance. It belongs to the technical field of machining tooling. Background technique: [0002] With the rapid development of the aerospace field, composite materials have been widely used in aircraft due to their advantages such as high strength, light weight, and good corrosion resistance. And tearing processing defects and other reasons make it very difficult to assemble holes in composite materials. At present, due to the limitation, specificity and economy of the use of automation equipment, manual assembly hole making is still dominant and irreplaceable. Traditional manual assembly hole making uses cemented carbide drills to process the initial hole, but the hole making The aperture range is small and easy to produce processing defects, poor hole quality and accuracy, unstable processing, low...

[0002] With the rapid development of the aerospace field, composite materials have been widely used in aircraft due to their advantages such as high strength, light weight, and good corrosion resistance. And tearing processing defects and other reasons make it very difficult to assemble holes in composite materials

At present, due to the limitation, specificity and economy of the use of automation equipment, manual assembly hole making is still dominant and irreplaceable. Traditional manual assembly hole making uses cemented carbide drills to process the initial hole, but the hole making The aperture range is small and easy to produce processing defects, poor hole quality and accuracy, unstable processing, low efficiency, dusty chips and polluting the environment, low tool life, high cost, high labor intensity, and with the continuous increase of production tasks , there is an urgent need for new hole-making tools and process improvements
