Connecting Mechanism of Precision Table to Its Driving System

为了建立精密进给平台系统，提出了基于四球式和气垫层式两种机构的连接方式。并将其与精密工作台的滚珠丝杠传动系统相结合，验证了这些连接机构的正确性和有效性。研究表明，所提出和研制的机构只在进给方向具有较高的刚度，即方向向刚度，同时在其他方向具有较高的柔度，以隔离不利的振动和干扰。

In this research, to establish a precision feed table system, the connecting two mechanisms based on a new concept, i. e., the four-ball type and air-cushioned layer type have been proposed. Furthermore, we ascertained the validity and effectiveness of those connecting mechanisms by incorporating them between the table and its ball screw type driving system of a precision table. And it has been make clean that the proposed and developed mechanisms the high rigidity only in the feed direction, i, e., direction-oriented rigidity, simultaneously having the high flexibility in other directions to isolate the unfavorable vibration and disturbance.
