机电一体化实训系统冲压单元——动力驱动设计
摘 要

随着社会生产水平的提高,生产规模的扩大,机电一体化冲压单元在生产过程中越来越重要。为了提高生产率，各企业都在尽可能多地应用机电一体化冲压单元。它通过计算机系统的智能检测及集成控制,大大提高了劳动生产力,降低了操作人员的劳动强度,加快了物料冲压,为企业节省了大量的劳力和时间, 在国民经济中发挥了巨大的作用。
典型的自动化生产线上的机电一体化系统冲压单元的设计包括：动力与驱动设计、结构与外型设计、机械手与运动设计、接口电路设计和PLC控制系统设计等部分。其中，冲压单元的结构与外型设计，是设计在较小的空间内设计出结构合理、工作安全的冲压单元；机械手的设计，要求结构简单，工作可靠，定位准确；动力驱动的设计，是设计机械手在整个运动过程中的动力；接口电路设计，是设计整个系统中的电气接口、各种传感器与PLC的接口及整个系统的布线设计；PLC控制系统的设计，是设计PLC通过对传感器采集到的信号的运算，根据运算结果控制各个运动执行部件。
本课题主要是研究基于机电一体化实训系统冲压单元中的动力驱动的设计。其中动力驱动装置主要是驱动机械手的运动，分别是水平方向通过步进电机驱动滚珠丝杠在横轴方向的前后运动，还有气压缸驱动的能在水平方向上前后运动的机械手运动。通过机械手三个自由度的运动可以完成货物的自动冲压。

Abstract

With the improvement of the level of social production, the expansion of production scale, the mechatronic stamping cell played a more and more important role in the manufacturing process. In order to raise the productivity, it has been used in various enterprises. It adopted an intelligent detection and integrated computer system control, greatly improving the labor productivity, reduced operator labor intensity, speed up the construction of the materials and cut down the labor and time in the large scale for industrial enterprises, which played a huge role in the national economy.
The design of a mechatronic stamping unit in a typical automated production line include: power-driven design, structure and exterior design, manipulator and movement design, interface with the electrical circuit design and PLC control system design part. The design structure and exterior of the stamping cell is to design a stamping cell with a logical structure and work safely in a lesser space；The design of manipulator requires simple construction, works safely and orient preciously; The design of power drive is to design the motivity of the manipulator in the whole motorial process; The design of interface and the circuit is to design the interface of the whole system including that of various sensors and PLC and disposing the circuit of whole system; The design of PLC is to design the operation of the informations that the sensors collect, and control every executive part accordingly.
The main issue is the power drive design of the stamping cell based on the electronic training system: the power drive device is mainly to drive the motivity of the manipulator, horizontal plane through the stepper motor-driven ball screws to drive the right-and-left and fore-and-aft motivity. Moreover, there are air-pressure-driven cylinders in the horizontal direction to control the fore-and-aft movement of the manipulator. Through the three degrees of freedom of the manipulator goods can be stamped automaticly.
