设计简介
本文对砂轮修整器作了较为系统的介绍，讲述了砂轮修整器的历史背景和将来的发展方向。基于砂轮修整器的发展现状，提出了一种新型丝杠磨床砂轮修整器结构。在设计过程中，对其结构进行了分析，使其能够完成修整砂轮外轮廓的动作。修整砂轮时修整轮与被修整轮的接触面能够保持垂直。对该机构进行了简单的受力分析；确定了各个零件的尺寸，并运用Pro/E软件设计出各零件的三维结构和组装图。用CAD软件画出了零件图和装配图。通过之前的计算选取电机，最后完成该机构的设计。

Abstract
In this paper, a newtypes griding wheel dresser was introduced. The historical background of grinding wheel dresser and future direction was described. Through the understanding of grinding wheel dresser, had a new screw design of grinding wheel dresser. In the design process, its structure was analyzed, so that it can complete trimming the outline of the griding wheel. The paper achieved when the dressing wheel and the contact was maintained vertical. Then the force of its simple analysis carried out to determine the size of each part, and use Pro/E software to design three-dimensional map of parts and assembly diagram. Using CAD software to draw diagrams and assembly drawings of parts. Selected by the calculation before the motor, the mechine was completed.
