Research on Reverse Reconstruction Technology of Drive Screws

Abstract

Reverse innovation design has always been an important topic in the field of engineering. The purpose of this paper is to solve problems in drive screws caused by their complex structure, demand for high shape accuracy and long cycles of design optimization. The reverse modeling technology, the Win 3D scanner and Geomagic Wrap are employed to collect the point cloud data of the drive screw, wrap them into a curved surface, and import them into the reverse engineering software Geomagic Design X to create its highly accurate 3D digital model. In this way, high precision guarantee can be provided for the optimal design of the drive screw, thereby shortening the innovation cycle and laying a technical foundation for the improvement of transmission performance. According to the error analysis software Geomagic Control, the error in the inverse model of the drive screw does not exceed 0.02 mm, which meets the industry’s needs. This model can be used for digital production, and can also provide high-precision model support for secondary innovation, which is of great significance for shortening the product design cycle and enhancing the competitiveness of the enterprise.
