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
