PDC钻头检测装置机械部分设计

[摘要]  在PDC检测装置主要结构中，主轴头是成形机的关键部分，它的
设计对机床的性能有重要的影响。该设计中，先确定了总体方案，运用步进电机和滚珠丝杠来实现总体的设计。并选择了感应同步器作为机床的检测装置，相应地确定了它的放大电路和接口电路。然后通过计算设计了成形机床的进给部分，包括导轨、滚珠丝杠、轴承和联轴器等等。最后通过计算选择了步进电机的型号。

[Summary]  In PDC in the detector set primary structure, the main axle neck
is shaper's essential part, its design has the important influence to engine bed's performance. In this design, had determined the first overall concept, the utilization step-by-steps the electrical machinery and the ball bearing guide screw realizes the overall design. And chose the induction synchromesh to take engine bed's detector set, has determined its amplifying circuit and the interface circuit correspondingly. Then designed through the computation has formed engine bed's to feed part, including guide rail, ball bearing guide screw, bearing and shaft coupling and so on. Finally chose through the computation has step-by-stepped electrical machinery's model
