Abstract

本实用新型为展成加工摆线针轮减速机针轮销 孔用的插齿刀。其齿廓曲线是由半圆弧和与半圆弧 两端点相切的两直线段组成,前角5°~8°,后角 2°~5°,刀体可为盘形、锥柄形和碗形,在插齿机 上,用同一把刀具,可展成加工同一销孔直径、不同齿 数、不同机型的针轮销孔。销孔尺寸精度,形位精度 提高一级。

Description

本实用新型涉及一种切削刀具,用展成法插削摆线针轮减速机的针轮销孔。
针轮是摆线针轮减速机的重要构件,针轮由针齿壳和针齿销组成,在针齿壳中心圆直径dp上均布有10~120个直径为dsp的半圆形销孔,销孔的分度精度和加工质量对减速机的性能影响极大。
长期以来,针轮销孔的加工是在专用钻床上,用分度机构及钻模依次进行钻孔,扩孔、铰孔,再在车床上车削到半圆。这种加工方法有以下缺点:1)因刀具磨损、销孔尺寸精度低;2)刀具结构刚度低,销孔形位精度难以保证,分度机构精度直接影响相邻孔距和累积孔距误差;3)只能加工灰铸铁针齿壳;4)生产率低,劳动强度大。
为解决上述问题,本实用新型提出一在插齿机上用展成法插削针轮销孔的插齿刀。
本实用新型所称的针轮销孔插齿刀是由合金工具钢刀体和均布于刀体上的刀齿构成,刀齿齿廓曲线是由半圆弧和与半圆弧两端点相切的两条直线段组成。刀齿齿廓的半圆弧半径R=2~15mm,直线段长度为1mm,刀齿的前角为5°~8°,后角为2°~5°,刀齿齿数Z0=11~40。刀体结构形式为盘形、锥柄形、碗形。
刀体材料采用合金工具钢,热处理至HRC63~66刀具制造技术要求按GB6082-85标准规定。
本实用新型的实施例如附图所示:
图1——针轮销孔插齿刀结构图
图中:1-盘形刀体;2-刀齿;3-前角r;4-后角α;5-刀齿中心圆do;6-刀体厚度H。
图2——刀齿齿廓曲线
图中:7-半圆弧段;8-直线段;
本实施例中,刀体采用盘形结构,刀体材料为w605Cr4V2,刀齿齿数Z0=31,刀齿中心圆直径dO74.68mm,前角γ=5°±8′,后角α=2°±5′,齿廓圆弧半径R=2.52+0.016 +0.01,直线段ab长度为1mm,齿顶圆直径d=79.68+0.10 +0.05,整体热处理HRC63~66。其余技术条件符合GB6082-85标准规定。
采用本实用新型所称的针轮销孔插齿刀有如下优点和效果:该插齿刀安装在插齿机上,用展成法插削的针轮销孔的尺寸精度可保证在E7之内;形位精度提高一级,销孔表面粗糙度Ra<1.6μ,相邻销孔距误差≤0.02mm,累积孔距误差≤0.04mm。劳动生产率提高2倍以上,单件加工成本降低50%。在插齿机上,改变挂轮,同一把插刀可展成加工同一销孔直径,不同齿数,不同机型的针轮销孔。用该针轮销孔插齿刀,可展成加工铸铁,碳钢、合金钢等材料的针轮销孔。
