这是一种使工业机器人的手臂转动的方法。它可以不通过齿条和齿轮,把多个油缸所得到的直线运动变为手臂旋转的驱动力。这种方法,可以改进利用油缸驱动时回转角小的缺点。 能使手臂自由俯仰的回转体安装在基座上,油缸安装在U形叉上,U形叉固定在转台上,使回转体可以自由旋转。活塞杆的顶端装在回转体突出的U形叉上可自由转动,这就构成了活塞曲柄机构, This is a way of turning the arm of an industrial robot. It can not be through the rack and gear, the cylinder obtained by a number of linear motion into a rotating arm driving force. This method can be used to improve the use of fuel tank drive when the rotation angle of the shortcomings. The swinging body which enables the arm to freely tilt is mounted on the base, the fuel tank is mounted on the U-shaped fork, and the U-shaped fork is fixed on the turntable so that the rotating body can rotate freely. The top end of the piston rod is mounted on the U-shaped fork protruding from the rotating body for free rotation, which forms the piston crank mechanism,
