横针机构的动态仿真研究

对用于多功能缝纫机中的横针机构进行了动态仿真研究。编制的横针机构的仿真软件实现了全部结构参数的动态输入,动态仿真。并可根据对横针距的设计要求,快速反求花模凸轮的轮廓。不同的横针距与直针距相配合,可以实现任意给定的缝纫线迹。求出的花模凸轮的廓线数据,可作为花模电子凸轮的设计参数,为横针机构的机电一体化提供了设计基础。

Study on Dynamic Simulation of Transverse Needle Mechanism

This paper studied dynamic simulation of transverse needle mechanism that was used for the multi-purpose sewing machine. The simulation software of transverse needle mechanism was programmed, which can dynamically input all structure parameters and realize dynamic simulation. This software can rapidly get the pattern cam contour according to the design requirements for the transverse stitch length. Through different transverse stitch length and different straight stitch length cooperate, multi-purpose sewing machines can realize to sew arbitrary thread trace. The parameters of the pattern cam contours can be used as the design parameters of pattern electronic cam. This paper provides design basis for the mechatronic transverse needle mechanism.
