Description
【考案の詳細な説明】
本案はドリル加工とリーマ加工を一つの工具で同時に行
える直溝型のドリルリーマに関するものである。[Detailed Description of the Invention] The present invention relates to a straight groove type drill reamer that can perform drilling and reaming simultaneously with one tool.
本件に軸線と平行に複数本（一般に２本）の直溝を設け
、ドリル用直刃とリーマ用直刃を交互に配置したドリル
リーマが知られている。A drill reamer is known in which a plurality of straight grooves (generally two) are provided in parallel with the axis, and straight blades for a drill and straight blades for a reamer are alternately arranged.
この工具は、下穴の有無、又取りしるの多少に関係なく
高精度の穴あけ及びその仕上げを行うことができる点で
すぐれているが、直溝・直刃の関係で２番取り量が少な
いので、１回転当りの送り量を多くすることができなく
て、加工時間に問題があった。This tool is excellent in that it can perform high-precision drilling and finishing regardless of whether there is a pilot hole or not, and regardless of the amount of recess. Since the amount of feed is small, it is not possible to increase the amount of feed per rotation, which poses a problem in machining time.
本案は直溝型ドリルリーマにおける上記の問題点を解決
することを目的とするもので、図面について構造を説明
すると、１は本体、２はシャンクで、その本体１に２本
の直溝３が対称的に設けられている。The purpose of this project is to solve the above-mentioned problems in straight groove type drill reamers.To explain the structure with reference to the drawings, 1 is a main body, 2 is a shank, and two straight grooves 3 are symmetrically arranged in the main body 1. It is set up as follows.
各直溝３の縁にドリル用直刃４とり−マ用直刃５が交互
に配置されている。Straight blades 4 for drills 4 and straight blades 5 for drills are alternately arranged on the edge of each straight groove 3.
ドリル用直刃４の先端には切刃４１、リーマ用直刃５の
先端には食付き部５１があり、その食付き部５１は切刃
４１より若干後退した位置にある。A cutting edge 41 is provided at the tip of the straight cutting edge 4 for a drill, and a chamfered portion 51 is provided at the tip of the straight cutting edge 5 for a reamer, and the biting portion 51 is located at a position slightly set back from the cutting edge 41.
そして上記リーマ用直刃５の先端部の回転方向前側に一
定長さの切欠き段部ａを設けて切削刃部５２を形成して
いる。A cutting edge portion 52 is formed by providing a stepped notch portion a of a certain length on the front side in the rotational direction of the tip of the straight blade 5 for reamer.
ドリル用直刃４の直径は、リーマ用直刃５の仕上げしろ
分だけ小さくなっているのは勿論である。Needless to say, the diameter of the drill straight blade 4 is smaller by the finishing allowance of the reamer straight blade 5.
又ドリル用直刃４には、逃げ面４２が形成されている。Further, the straight cutting edge 4 for a drill has a flank 42 formed therein.
本案直溝型ドリルリーマは上記のように、そのリーマ用
直刃５の先端部に、一定長さの切削刃部５２があるから
、先端部は全部の刃が穴あけ切削を行い、しかも切削刃
部５２を形成した分り−マ用直刃５の面積が減少する、
即ち２番取り量が増加するので切削性が向上し、工具１
回転当りの送り量を多くしても面粗度を低下させること
がない。As mentioned above, the straight groove type drill reamer of the present invention has a cutting blade part 52 of a certain length at the tip of the straight reamer blade 5, so all the blades at the tip perform drilling and cutting, and the cutting blade part As a result of forming 52, the area of the straight blade 5 for mare is reduced.
In other words, since the amount of 2nd cut increases, the machinability improves, and tool 1
Even if the feed rate per rotation is increased, the surface roughness will not decrease.
従って形状精度・位置精度にすぐれた穴を１回の加工で
能率良く加工できる効果がある。Therefore, it has the effect of efficiently machining holes with excellent shape accuracy and positional accuracy in one machining process.
