1、分析中空玻璃生产线实际构造和运动情况,查明该机构由多少个构件织成,找出机架及原动件,根据相连接两构件间接触情况及相对运动件质,确定各个运动副类型,并安装顺序标上字母。
1, analysis of hollow glass production line structure and actual movement situation, find out the mechanism by the number of components made out of the original frame and, according to the connection between two members contact and relative motion, determine the motion type and installation sequence of letters.
2、分析原动部分运动经过传动部分传递到工作部分过程。从原动件开始到各个从动件,沿着运动传递路线,并且按照在各构件上标上数字编号。
2, analysis of the motion driving part through the transmission part of the transfer to the work process. From the original to each follower motion along the route, and in accordance with the number of components in superscript numbers.
3、选择与之多数构件的与之相平行平面作为绘制机构运动简图投影面。
3, the parallel plane of the majority of the components is chosen as the projection surface of the drawing mechanism.
4、选样比例要合适,根据中空玻璃生产线运动尺寸,确定各运动副之间相对位置,用规定符号将各运动副表尔出来,用直线或曲线将向一构件上各运动副元素连接起来,用箭头标注机构原动件在所示位置时运动方向,绘制出所要画机构运动简图。
4, select suitable proportion, according to the insulating glass production line movement size, determine the relative position between the pair, with each pair rule table, out with a straight line or curve will be linked to the movement of a component element, marked by arrows mechanism of the motion in the position shown in the direction. Draw to draw the movement diagram.
在绘制过程中要注意:转动副的小圆,它要画在转动副两构件相对的中心位置,这是为了准确地表达中空玻璃生产线构件间的相对运动,而移动副的导路与组成移动副两构件相对移动方向要一致;表示高副的曲线,其曲率中心的位置也要和实际轮廓的曲率中心—致。
Note: in the process of drawing revolute round, it will draw in the center position of the rotary member relative to the two side, this is in order to accurately express the relative motion of insulating glass production line between components, and the moving guide way and the composition of the mobile side two side member relative moving direction to be consistent; the curve indicates a high side the center of curvature, the curvature center of the will and the actual contour caused by.
