平面接触面多边形刀架接口第3部分:F和A型带柄从动刀架的联轴器

[中文适用范围]： 本文件规定了具有平面接触面的多边形截头刀具夹头（PTI）的耦合尺寸。这些截头部分是机床（例如：车床、镗床中心）上刀具载体（在切削过程中不旋转）与刀具之间的接口的工具侧部分。本文件规定了一种适用于ISO 5686-1中定义的三种工具侧接口类型中的两种（F型和A型）的耦合类型。所有类型的工具截头设计相同。- F型截头在接触面有两个用于冷却液供应的孔（F =流体），可以在两个安装位置使用（偏移180度）。- A型截头在接触面上有两个用于主要冷却液供应的孔和另外两个用于为夹持器（驱动刀具）提供密封空气的孔（A=空气）。可以实现偏移180度的安装位置。一种弹簧式直销属于夹持器，以防止错误插入。 [外文原描述]： This document specifies the dimensions of couplings for driven tool holders with polygonal taper shanks with flat contact surface (PTI). These shanks are the tool-side part of the interface to the (in cutting process non-rotating) tool carrier of machine tools (e.g. turret lathes, turning centres). This document specifies a coupling type that applies to two of the three tool-side interface types defined in ISO 5686-1 (F, A). The tool shanks themselves are designed identically for all types. — Shank type F has two holes for the coolant supply (F = fluid) on the face contact for use in two installation positions (offset by 180°). — Shank type A has two holes on the face contact for the primary coolant supply and additional two holes for supplying the tool holder (driven tool) with sealing air (A = air). An installation position offset by 180° is possible. A spring-type straight pin belongs to the holder and avoids incorrect insertion.
