本文将高速自动送料凸轮连杆组合机构的运动分解为机构刚体运动和夹持器纵向振动的迭加。计入了连杆机构中构件的弹性。在此基础上,建立了该类组合机构综合的一般方法。在闭环约束方程中引入状态变量和设计变量,不仅方便了整个综合过程,而且使该类综合问题一般化。其基本思想对其他组合机构的综合具有普遍意义。本文最后给出一个计算实例及考虑机构弹性变形时的凸轮廊线图。
In this paper, the motion of the high-speed automatic feed cam link mechanism is decomposed into the superposition of the rigid body motion and the longitudinal vibration of the clamper. Takes into account the flexibility of the components in the linkage. On this basis, a general method for the synthesis of such composite institutions is established. The introduction of state variables and design variables into the closed-loop constraint equations not only facilitates the entire synthesis process, but also generalizes such comprehensive problems. Its basic idea has general significance for the synthesis of other composite institutions. At the end of this paper, we give a calculation example and the corridor diagram of the cam when considering the elastic deformation of the mechanism.
