Abstract

本实用新型公开了一种滚珠螺纹铣刀,它由切削锥(1)、杆部(2)和锥柄(3)组成,排屑槽为直槽,切削锥刃部为双圆弧偏心铲齿齿形。本实用新型有益效果在于:所述滚珠螺纹铣刀是专门用于加工滚珠内螺纹的整体式铣刀,铁屑成碎块排出,不会对已加工成形的面产生擦挂,加工出的螺纹表面质量好,形状尺寸稳定,工效高成本低,同一把刀具可加工左螺纹和右螺纹,螺纹节圆尺寸根据需要可任意调节。

Description

滚珠螺纹铣刀
技术领域
本实用新型涉及一种内螺纹切削刀具,特别是滚珠螺纹铣刀。
背景技术
当前滚珠内螺纹加工一般生产中常采用车削或专用丝锥攻丝,车削加工刀具刃形不好控制,需经常刃磨,复磨后刃形变化大,费工费时;专用丝锥为固定尺寸刀具,尺寸不能调整,多次复磨后尺寸变化大。
实用新型内容
本实用新型的目的在于克服现有技术的缺点,提供一种加工滚珠螺纹尺寸稳定,表面质量高,尺寸可根据需要任意调节的滚珠螺纹铣刀,它生产效率高,多次复磨后齿形不变,耐用度高。
本实用新型的目的是通过以下技术方案实现的:滚珠螺纹铣刀,它由切削锥、杆部和锥柄组成,切削锥刃部为双圆弧偏心铲齿齿形,整个齿形为圆滑过度,无尖角,顶刃倒刃后角α为8°~10°,排屑槽为直槽,槽形角θ为57~63°。
通过上面的叙述可以看出,本实用新型具有以下优点:专门用于加工滚珠内螺纹的专用杆式成形铣刀,锥柄装夹定心好,定位精度高,拆卸方便,杆部为顺锥度,加强了使用的刚性,刃部复磨后齿形不变。用一把刀可加工右螺纹和左螺纹,达到一刀多用目的。加工出螺纹齿形对称,表面粗糙度好,使用时无需多次进刀,节约了人力物力,降低了工时成本。
附图说明
图1为本新型结构示意图
图2为K向视图
图中,1-切削锥,2-杆部,3-锥柄,4-排屑槽,5-切削锥刃部。
具体实施方式
下面结合附图进一步描述本实用新型:如图1和图2,滚珠螺纹铣刀由切削锥1、杆部2和锥柄3组成,排屑槽4为直槽,排屑槽槽形角θ为57~63°,切削锥刃部5为双圆弧偏心铲齿齿形,顶刃倒刃后角α为8°~10°。
使用时,由锥柄定位,杆部锥度增加了使用的刚性,直槽容屑槽排屑流暢,刀具安装时无需调整螺纹升角,采用立体干涉法切制滚珠内螺纹,因此铁屑成碎块状排出,不会对已加工成形的面产生擦挂。同一把刀可加工右旋或左旋螺纹,螺纹节圆尺寸根据需要可任意调节。
