摘要本文介绍了一种加工深孔内螺纹的滚压加工装置。该装置拟采用行星轮系结构，主运动由摆动装置传给轮架、带动螺纹滚轮作往复滚压运动；进给的螺旋关系可由车床给定也可由分别固定在工件和行星轮架的螺纹副模具给定。滚压方式不会产生加工切削，可提高螺纹的光洁度和节省工件材料。本文详细的介绍了滚压装置和摆动机构的设计过程和思路。在滚压装置中，创新的一点是采用曲柄摇杆机构实现了滚压装置的往复滚压运动。另外本文还介绍了如何保证滚压螺纹加工精度，以及螺纹引导模具设计等问题。68904

Title    design of the screw hole rolling process device          

Abstract

This paper introduces a device for rolling deep hole.The device adopts the planetary gear structure, the main movement by swinging device to wheel frame, drive roller for reciprocating motion of rolling thread.The screw relationship can be given by a lathe given by a screw die fixed separately in the work piece and a planetary wheel bracket.The rolling method can not produce the machining cutting, but can improve the thread's smoothness and save the work piece material.The design procedure and the thinking of the rolling device and the swinging mechanism are introduced in detail in this paper.In the rolling device, the crank rocker mechanism is adopted to realize the reciprocating rolling motion of the rolling device.In the rolling device, the crank rocker mechanism is adopted to realize the reciprocating rolling motion of the rolling device.In addition, this paper also introduces how to guarantee the accuracy of rolling thread, and the design of the thread guide die.

Keywords  Deep hole internal thread   Rolling process  Crank connecting rod  Planetary wheel  Thread guide die
