一、前言小直径弧齿锥齿轮铣刀盘是指名义直径为1/2″、1(1/10)″、1(1/2)和2″的四种铣刀盘,又叫做小模数铣刀盘。它们都是整体结构的双面铣刀盘。目前国内有关资料介绍2″盘形铣刀只有4个刀齿,但现在国外先进的2″铣刀盘有16个刀齿。当然,刀齿数量多,被加工零件的光洁度就高,精度好,刀具寿命长,但刀具制造也就难度大。为了保证产品质量,并结合我厂目前制造铣刀盘的技术水平,2″铣刀盘采用了8个刀齿的结构形式。关于这种刀盘的设计与切齿计算以及刀具设计图的绘制等,叙述如下。
I. Introduction Small-diameter spiral bevel gear milling cutter plate refers to the nominal diameter of 1/2 “, 1 (1/10)”, 1 (1/2) and 2 “four milling cutter, also known as small mold The number of milling cutter plate.They are the overall structure of the double-sided milling cutter disc.At present, the domestic information on 2 ”disc cutter has only four cutter teeth, but nowadays foreign advanced 2“ milling cutter disc has 16 cutter teeth. Of course, the number of cutting teeth, machined parts of the finish is high, good precision, long tool life, but the tool is also difficult to manufacture. In order to ensure product quality, and combined with the current factory Milling Cutter technology level, 2 ” Milling cutter disc with 8 teeth structure. The design of the cutterhead, the calculation of the cutter and the drawing of the cutter design, etc. are described below.
