Abstract

本实用新型涉及一种铰刀。一种手用铰刀，由圆柱形导向柱和与其连为一体的刀体构成，刀体由一体连接的刀部和刀柄构成，刀部上设有8组螺旋刃，螺旋角是15°，圆柱形导向柱的直径小于刀部的外径，刀部前端与圆柱形导向柱的尾端连为一体，且圆柱形导向柱的尾端设有环形槽，螺旋刃的前端部处于环形槽处。该手用铰刀的优点是铰孔效果好，铰出的孔内壁光滑，洁面度高。

Description

一种手用铰刀
技术领域
本实用新型涉及一种铰刀。
背景技术
铰刀分为手用铰刀和机用铰刀，现有的手用铰刀在铰孔时，定位不准确，转动时容易轴向偏离。此外，现有手用铰刀上的刀刃结构不合理，尤其是刀刃刃数以及刀刃与轴向的夹角的角度不合理，导致手用铰刀铰孔效果差。
发明内容
本实用新型的发明目的是提供一种结构新颖，铰孔时导向定位准确，铰孔效果好的手用铰刀。
本实用新型所采用的技术方案是：
一种手用铰刀，由圆柱形导向柱和与其连为一体的刀体构成，刀体由一体连接的刀部和刀柄构成，刀部上设有8组螺旋刃，螺旋角是15°，圆柱形导向柱的直径小于刀部的外径，刀部前端与圆柱形导向柱的尾端连为一体，且圆柱形导向柱的尾端设有环形槽，螺旋刃的前端部处于环形槽处。
采用上述技术方案设计的手用铰刀，通过圆柱形导向柱使铰刀导向定位准确；螺旋刃共8组，螺旋角是15°，这种螺旋刃的结构配合在前定位的导向柱，使得铰孔效果好，铰出的孔内壁光滑，洁面度高。
附图说明
图1：本实用新型实施例的结构示意图。
具体实施方式
下面是结合附图1对本实用新型的技术方案作进一步详细描述。
如图1所示的一种手用铰刀，由圆柱形导向柱1和与其连为一体的刀体构成，刀体由一体连接的刀部2和刀柄3构成，刀柄3处于刀部2的尾端，刀部3上设有8组螺旋刃21，螺旋角θ是15°，圆柱形导向柱1的直径小于刀部2的外径，刀部2前端与圆柱形导向柱1的尾端连为一体，且圆柱形导向柱1的尾端设有环形槽11，螺旋刃21的前端部处于环形槽11处，导向柱1在前用于导向定位。
使用时，导向柱1先深入所要加工的通孔，导向定位，防止铰孔时轴向偏离，螺旋角θ是15°的8组螺旋刃21配合在前定位的导向柱1，使得铰孔效果好，铰出的孔内壁光滑，洁面度高。
