钻孔工具的命名和基本部位(扭曲位)

Drill bit Nomenclature:

钻孔是切割或源自固体材料的圆孔的过程。有很多方法可以进行钻探。旋转工具(钻)而不是工件,并且沿其轴线进入材料。
例如,根据材料,凹槽的数量和类型,钻头尺寸,柄型(直或锥度)和切割点几何形状等。然而,最常见的钻头类型是图中所示的凹槽钻。

钻头命名法

钻机结构:钻井结构:

麻花钻是由三个组件:太瓦ist drill is made up of three components:
- 小腿
它是钻孔的部分,它夹在主轴中。柄部可以是直的或锥形的。直柄钻头与卡盘一起使用。锥形柄钻具有自持式胶带,可直接安装在钻头上。在锥度柄上,使用的另一个术语被称为唐。这适合主轴套筒的插槽。
– Body
它是点和柄之间的部分。
- 钻点

钻孔工具命名:

  • Cutting Diameter:
“最大直径在点后面的土地顶部测量”

  • 背部锥度 -
直径略微向钻头的柄端略微减少,这被称为“背锥形”。后锥度提供钻头和工件之间的间隙,防止摩擦和热量

  • Flute Length: Flute Length:
“从钻点测量的长度到长笛跳动的末端”

  • Land:
“The part of the drill body “The part of the drill body between the flutes” between the flutes”
- 土地为钻头提供了大部分扭转力量
- 降低碎路宽度增加芯片空间,但降低了强度。

  • 腹板
“厚度”测量的厚度在长笛“长笛”底座上的底座上测量
- 有助于钻头的扭转力量。

  • 螺旋角度:螺旋角度:
在平行于平行于钻轴的轴和陆缘的轴的轴线平行的线之间形成的角度。
螺旋角度一般分为三类:螺旋角度一般分为三类:
- 慢螺旋 - 12°至22°螺旋角度
- 定期螺旋-28°至32°螺旋角度
- 快速螺旋 - 34°至38°螺旋角度

  • 边缘:
“圆柱形部分”的圆柱形部分是未切割不切开以提供间隙“以提供间隙”的土地的圆柱形部分
- 直径的平衡减小,称为“清除直径”或“身体间隙”。

  • 切割嘴唇切割嘴唇
“从”从钻头的中心延伸到钻头的中心延伸到外径“外径”的切割边缘的切割边缘
- 在大多数标准钻头上,切削刃应形成直线。
– Some specialty and high performance drills have curved cutting lips.

  • Chisel Edge Chisel Edge
“卷筒末端的边缘,”网上末端的边缘,连接切割嘴唇“连接切割嘴唇”
– The chisel edge does not cut does not cut- it penetrates displacing the workpiece material.

  • 凿子边角凿凿边
“The angle formed between the “The angle formed between the chisel edge and the cutting lips” chisel edge and the cutting lips
– The chisel edge angle is generally 125° to 135°

  • 观点:
The point is the cone shaped end and it does the cutting. It consists of the following:
(A) dead center:It is the sharp edge at the extreme tip of the drill. This should always be the exact center of the drill.
(b)嘴唇:这些是钻头的切削刃。
(c)脚跟:It is the portion of the point back from the cutting edge.
