摘 要为了提高生产效率和焊接质量,满足特定的工作要求,本题设计用于焊接的关节型机器人的手腕和末端执行器
根据机器人的工作要求进行了机器人的总体设计
确定机器人的外形时,拟定了手腕的传动路径,选用直流电动机,合理布置了电机、轴和齿轮,设计了齿轮和轴的结构,并进行了强度校核计算
传动中采纳了软轴、波纹管联轴器和行星齿轮机构,实现了摆腕、转腕和提腕的六个自由度的要求
设计多采纳了标准件和常用件,降低了设计和制造成本
关键词:自由度;焊接;手腕AbstractIn order to improve the production efficiency and welding quality, to meet the specific requirements of the work, the design of this thesis is used for the wrist of welding articulated robot and the end of the actuator
According to the requirements of the robots’work, we make overall design of the robot
When determining the shape of the robot, drawing up the transmission path of the wrist, selecting of DC motor, arranging the motor, the shaft and the gear reasonable, and checking the strength
The transmission apply to flexible shafting, bellows coupling and planet
