摘 要
PCB数控二轴钻铣床是一种机电一体化的产品,是专用于PCB加工的一轴一联动数控机床。
本机床采用先进的直线滚动轨迹、高精度滚珠丝杆和交流伺服电机;涉及微电子、计算机、自动控制、精密机械、图像处理等多种技术,综合性强,知识、技术、资金密度高,适用于高精度PCB的成形加工。
本文对PCB机床的整机系统结构、伺服进给机构、工作装置、机电匹配进行了讨论和分析,特别是对整机系统结构和伺服进给机构进行了详细的设计,主要包括机床动力参数、整机的结构布置、伺服系统的选择以及滚珠丝杆、滚动导轨、联轴器、滚动轴承、交流伺服电机、高速电主轴等关键零部件的选择和设计。
除此之外还对冷却系统,润滑系统等做了简单的选择,因为本次设计之重点在于机械结构以及机械传动系统,所以其他的像数控程序,变频器之类的就省略了许多,尽请谅解!
关键词: 数控机床,印刷电路板,伺服系统,机电匹配
ABSTRACT
PCB NC two-shaft drilling-milling machine tool is a kind of mechanical-electric integrative product and the one-shaft linkage NC appropriative print equipment based on the machining of PCB (Printed Circuit Board).
The machine tool adopts advanced beeline rolling oriented track, high precision ball bearing screw shaft and AC servo electromotor technique, deals with many studies including micro-electronics, computer, auto control, fine mechanic sand image manipulation, its comprehension is strong and its knowledge, technique and found density is high. It is used to the milling and drilling of high precision PCB.
The article discusses and analyzes the holistic system structure, servo feeding organ, working organ, NC organ and machinery electricity matching, and has carried out detailed designing and studying of holistic system and servo feeding system mainly including the estimation of driving parameter of the machine tool, the design of holistic structure layout, the selection of servo system, and the selection and proofing of key parts including ball bearing screw shaft, beeline oriented track, crosshead, ball bearing, AC servo electromotor, principal axis.
In addition to the cooling system, lubrication system, and so do a simple choice, because this focus on the design of the mechanical structure and mechanical drive system, like the other NC procedures, such as the frequency converter to omit a lot, do Please understand!
