喷漆机器人设计-小臂系统设计大学论文.doc

摘要 在当今大规模制造业中，企业为提高生产效率，保障产品质量，普遍重视生产过程的自动化程度，喷漆机器人作为自动化生产线上的重要成员，逐渐被企业所认同并应用。 本文首先简要介绍了喷漆机器人的研究背景、意义和现状。接着，进行总体方案的设计论证，确定了关节型坐标形式，采用步进电机驱动，选择滚珠丝杠、链轮链条和锥齿轮三种传动方式，利用弹簧进行平衡，研究出合理的设计方案。最后，设计小臂系统，通过对小臂系统的受力分析，设计小臂和腕部结构，计算关节转动需要的力矩，选择并设计出符合要求的电机、滚珠丝杠、链轮、锥齿轮和弹簧等，在确定各个零件和部件合理的安装位置后，完全实现小臂俯仰30度、腕摆120度和腕转120度的动作要求。 关键词 喷漆机器人 小臂系统 步进电机 摘要 Title Painting Robot - Forearm Systems Design Abstract In todays large-scale manufacturing, enterprises in order to improve productivity, attach importance to the degree of automation of the production process, the painting robots as an important member in automated production lines have been gradually recognized and adopted. This paper briefly describes the research background, the meaning and the current situation of the painting robot. Then, the paper gives the overall scheme of design, determines coordinates of the whole joint, uses a stepping motor to drive, selects a ball screw, chain sprockets and bevel gears three kinds of transmission type and use spring to balance so that work out a reasonable design programs. Finally, design and calculation of the arm system, through the stress analysis of the arm system in order to design the structure of forearm and wrist, calculate moment of force of the joint rotation, select and design to meet the requirements of the motor, ball screw, sprocket, cone gears, springs and so on. Determined the installation location of the various parts and components, so as to realize the movement requirements of arm pitch of 30 degrees, wrist swing of 120 degrees and the wrist twirl of 120 degrees.
