座式焊接变位机回转机构设计 摘 要 焊接变位机已成为制造业的一种不可缺少的设备，在焊接领域把它划为焊接辅助机型式系列和品种规格约有十余个系列百余个品种，正在形成一个新兴行业。本题目是设计能载重1.0工件，进行全位置焊接的变位机械。主要内容是关于焊接时回转的控制、电机选择、减速器的选择、各个轴和轴承的确定以及校核等等。　　设计的具体过程是根据预定的载荷和要求的焊接速度确定设备所需要的电机类型，包括：电机的转速、额定功率、电压电流等，在此基础上计算轴的相应配件的型号，并且对其进行相关的强度、使用寿命等的校核最后使用CAD软件绘制相关的零件图总装图。　　 ：焊接变位机机械设计BLOCK-TYPE WELDING POSITIONER ROTARY MECHANISM DESIGN ABSTRACT Welding positioner has become indispensable manufacturing equipment, in the welding area it designated as welding auxiliary machines. Series and products specifications on the type of case, has been available, and nearly a dozen more series, more than one hundred varieties and specifications, is forming a new industry. This subject is designed to load 1.0t parts, for all position welding of Block Variable-bit machines. Mainly on the welding machine of the rotary turning the control, motor selection, the choice of reducer, worm shaft and bearing all the determination and checking, and so on.  The specific process design is based on pre-load and required welding speed to determine the equipment needed to motor types, including: motor speed, rated power, voltage and current, calculated on the basis of this axis and the corresponding parts of the model size, and its associated strength, service life can be checked. Fragment using CAD software, the relevant parts diagram, assembly drawing out. KEY WORDS: welding positioner, reducer, motor type, mechanical design 目 录 摘 要……………………………………………………………ABSTRACT……………………………………………………………Ⅱ 目 录……………………………………………………………前 言……………………………………………………………第一章 焊接变位机械性能及结构…………………………………… §1.1 焊接变位机械……………………………………………… §1.2 焊接变位机械应具备的性能……………………………… §1.3 焊接变位机的功能及结构形式…………………………… §1.4 主自由度及全功能焊接变位机……………………………第二章 焊接变位机方案设计……………………………………§2.1 焊接变位机整体方案设计………………………………… §2.1.1 座式焊接变位机的用途及结构形式……………………… §2.1.2焊接变位机的驱动系统…………………………………… §2.1.3 设计方案简介………………………………………………§2.2 回转机构的设计……………………………………………… §2.2.1 回转机构传动简图………………………………………… §2.2.2 原始数据…………………………………………………… §2.2.3 工作条件……………………………………………
