The benzene is very volatile , toxic and carcinogenic . It does harm to the workers heavily when the protection is absent . So different kinds of painting robot s appeared and developed greatly . A joint type painting robot was designed in this paper . Ithad six degrees of freedom . The wrist had three degrees of freedom and the other joints had three degrees of freedom . The painting robot ’s joints were drivenby motors . Parallelogram structure was used in the robot . The motor which was installed on the waist turning table droved the forearm indirectly through the parallelogram structure . The structure avoided installing the motor directly on the joint to reduce the forearm ’s weight . So the burden of the motors which drive the upper arm and the waist were reduced . Also this structure made the forearm realize balance itself and reduce the static torque . Aluminum alloy was used greatly in the robot , so the weight of the robot was reduced . Also the dynamic performance was improved . Keywords : painting robot ; joint ; structure design 充值下载即送 CAD 图纸, QQ 36396305 1 目录摘要..................................................................................................................
