伸臂式焊接变位机设计 学 生 专 业：机械设计制造及其自动化 指导教师：摘 要：焊接变位机运动系统的设计是焊接变位机方案设计的核心内容，而焊接变位机运动自由度的确定是其前提条件。焊接变位机的关键是对变位机进行最佳位置焊接所需要的运动自由度的设计，如平动或转动的设计。伸臂式焊接变位机是将工件回转，翻转，以便使工件上的焊缝置于水平和船形位置的机械装置。伸臂式焊接变位机是应用最广泛的一种焊接变位机，载重量一般不超过1吨。伸臂式焊接变位机的主体部分是翻转机构、回转机构、底座。本设计主要是设计翻转机构的减速装置、回转机构的减速装置、。以及个部分和零件的个参数的选择。伸臂式焊接变位机焊接变位机有利于实现最佳位置的焊接过程。提高工作效率、降低疲劳强度并达到良好的焊缝成型。关键词：伸臂式焊接变位机；翻转机构；回转机构Style design of welding positioner Name：hanqiudi Major：Machinery Automation Tutor：xiezhedongAbstract :Abstract is The welding dislodgement machine kinematic scheme design is the core content of the welds dislodgement machine plan design. But the welds dislodgement machine movement degree of freedom is the prerequisite situation. The key of welding dislodgement machine is the design of movement degree in the best position welding,such as plate or rotation design.Stretching arm-the welding dislodgement machine is rotating and turning over the specimens, in order to set the welded joint to the horizontal and the hull shape position mechanism. Stretching arm-welding dislodgement machine is one kind of the most applied widespread welding dislodgement machine, the load-carrying capacity generally does not surpass one ton. the stretching arm-welding dislodgement machine main body part is turning over the organization, rotation organization, foundation. This design is mainly the design of the decelerating device in the turning over organization and rotating organization, as well as part and components parameter choice. Stretching arm- welding dislodgement machine is advantageous to the realization the best position welding process, improves the working efficiency, reduces the fatigue strength and achieves the good welded joint shape.Key words:stretching arm-welding dislodgement machine;turning over organization; rotation organization目 录题 目 1摘 要11 引 言11.1 开发焊接变位机的意义和目的11.2 焊接变位机目前的发展状况11.2.1 国内焊接变位机的产品简介11.2.2 国外焊接变位机的产品简介11.3 本次设计的意义和工作内容22 伸臂式焊接变位机总体方案设计22.1 设计要求22.2 总体方案的确定23 伸臂式焊接变位机的设计33.1 伸臂旋转减速器的设计33.1.1 伸臂旋转减速器的传动方案简图33.1.2 选择电动机33.1.3 确定传动比43.1.4 计算传动装置的运动和动力参数53.1.5 V带轮的设计计算63.1.6 高速级蜗轮蜗杆设计93.1.7 低速级蜗轮蜗杆设计113.1.8 轴的校核123.1.9 轴承寿命的计算153.1.10 较核轴上的键的强度163.2 工作台回转机构的设计173.2.1 总体传动方案简图173.2.2 选择电机173.2.3 确定传动比183.2.4 计算传动装置的运动和动力参数183.2.5 V带轮的设计计算193.2.6 高速级蜗轮蜗杆设计223.2.7 低速级蜗轮蜗杆设计243.2.8 轴的校核
