设计简介
摘 要
本文全面阐述了电梯导轨专用龙门刨床的结构原理，设计特点，论述了采用伺服电机和滚珠丝杠螺母副的优点。详细介绍了电梯导轨专用龙门刨床的结构设计及校核，并进行了分析。另外汇总了有关技术参数。
高速度、高精度、高效率和高刚度已成为当今数控机床发展的主要方向，普通龙门机床一般只能进行单面，当零件的另一个表面时，需要加装一个直角转换头或者调转零件的面后重新装夹，这不但增加了机床操作者的劳动强度，影响效率，并且重新定位装夹也降低了零件的精度，为了弥补这些不足，龙门电梯导轨专用龙门刨床便应运而生。电梯导轨专用龙门刨床一次装夹就能实现工件，这大大提高了零件的精度和效率，降低生产成本，因此五面体电梯导轨专用龙门刨床成为当前数控机床行业重点研究的对象之一。
其中着重介绍了滚珠丝杠的原理及选用原则，系统地对滚珠丝杠生产、应用等环节进行了介绍。包括种类选择、参数选择、精度选择、循环方式选择、与主机匹配的原则以及厂家的选择等。

Abstract
This paper expounds the structure principle, special elevator guide Longmen planer design features, discusses the advantages of using servo motor and ball screw nut pair. Introduces the structure design and check of elevator rail special Longmen planer, and analyzed. In addition a summary of the relevant technical parameters.
High speed, high precision, high efficiency and high stiffness has become the main direction of the development of CNC machine tools, machine tools generally only for a single ordinary Longmen, when one of the other parts of the surface, the need to install a rectangular head or surface conversion switch after clamping again, but this does not increase the intensity of labor, machine tool the effects of the operator efficiency, and re positioning and clamping also reduces the accuracy of the parts, in order to make up for these shortcomings, Longmen Longmen special elevator rail planer will emerge as the times require. The elevator guide special Longmen planer clamping a workpiece can be realized, which greatly improves the precision and efficiency of parts, reduce the production cost, so the five face special elevator guide Longmen planer has become one of the key object of study of the CNC machine tool industry.
Which focuses on the principle and selection principle of ball screw, ball screw system of production, application and other aspects are introduced. Including the principles and manufacturers selection, parameter selection, selection, selection, cycle accuracy and host selection of a matching etc..
Keywords: Elevator Guide for Longmen planer, numerical control, servo motor, ball screw
