     ABSTRACT
This paper is based on the machinery design and machinery principle and the 3d drawing software and related knowledge and theory, by collecting relevant data of sewing machine and reading the related literature books and referring to the sewing machine in the tailor shop, first of all, design the main parts institutional model of the sewing machine, secondly use the Solidworks 3D drawing software to conduct the part modeling which was designed well, and  then conduct assembly design which the parts was built, get the corresponding assembly model, finally conduct movement simulation to the corresponding assembly model.
Key Words: sewing machine, Solidworks, part modeling ,assembly design, movement simulation
