一种小口径螺套加工专用快换工具

A Special Quick Change Tool for Machining Small Diameter Screw Sleeve

本文针对常见加工螺套过程中存在的装夹螺纹变形、螺纹破坏以及小口径螺套内螺纹无法精密加工等情况,介绍一种可以解决上述加工难点的专用快换工具。该工具主要由螺套连接筒与螺套支撑筒两部分组成,在加工具体工件时,根据工件螺纹尺寸大小,选择对应的连接筒和支撑筒,并将其与三角卡盘底座通过定位结构定位可靠后进行工件螺纹攻丝。使用该工具可有效提高螺套加工合格率和加工效率。

This paper introduces a special quick change tool which can solve the above difficulties,such as the deformation of clamping thread,the damage of thread and the failure of precision machining of internal thread of small diameter screw sleeve.The tool is mainly composed of two parts:the screw sleeve connecting cylinder and the screw sleeve supporting cylinder.When processing a specific workpiece,the corresponding connecting cylinder and supporting cylinder are selected according to the thread size of the workpiece,and the workpiece thread tapping can be carried out after the positioning structure is reliable between the tool and the triangular chuck base.Using this tool can effectively improve the qualified rate and processing efficiency.
