毕业设计：基于自动控制环壁厚检具设计.doc

摘 要 本次毕业设计的题目是。 而步进电动机是由单片机控制。当工件到了指定的位置时按启动键，单片机接收到信号时，给步进电动机1脉冲，使步进电动机1转动，从而移动侧头使它与接触，同时启动电动机使。这时位移传感器把测到的数据传送到单片机，当得到最大值时输出测量值。 此检具的特点是：操作简单，减少了加工工序，提高了工件的性能，工作效率高，加工精度高，工件可以大批量生产，对环境的要求较低。 关键词：检具；；电动机：单片机控制Abstract The graduation design is the subject of the design of automatic control the thickness of the circle wall tool. This design is composed by the mechanical system design and the control system design, which includes the gear drive design and the choice, the ball bearing guide screw design and chooses, motor machine choice and installment mechanical system design, relating test system control design and choice. Stepper motor is controlled by microcomputer. When the work piece is moved to the appointed position, pressing the activate button then the microcomputer receives the signal and pulses the stepper motor 1 to run, thus the measuring head moves and connected with the wall of the ring. At the same time, activate motor 2 to rotate the work piece slightly，Here while the translation sensor carries the measured data to the microcomputer,, and outputting the measured value when it is maximized and minimized. The characteristic of the inspection instrument is described as follow: Easy to operate, having decreased the manufacturing process and improved working performance, having high working efficiency and high manufacturing accuracy, the products can be produced in large quantities, having lower environmental demand. Key words: detector; Automatic detection; electromotor; SCM control　 第1章 绪论 1 1.1 设计题目 1 1.2 设计总体 1 1.2.1 设计参数 1 1.2.2 方案设计 1 第2章 自动检测装置机械传动部分的计算 2 2.1 选择电动机 2 2.2 直齿圆柱齿轮部分的计算 7 2.3 轴的设计计算 11 第3章 电路系统的设计 13 3.1 芯片的选择及连接 13 3.1.1 芯片的选择 13 3.1.2 8051基本电路 18 3.1.3 8051与ADC0809的连接 19 3.2 驱动电路 19 3.3 功率放大系统的设计 20 第4章 软件部分的设计 23 4.1 主程序的设计 23 4.2 检测部分子程序 24 4.3 显示部分子程序 25 第5章 总结 26 参考文献 27 致 谢 28 附录1 29 附录Ⅱ 33  绪论 设计题目 本次毕业设计的题目是基于自动控制环壁厚检具的设计。机械量测试技术是现代实验科学非电量测量中的重要组成部分。它是根据各种物理效应的实验原理，采用相应的实验和测试手段，对所研究的机械进行机械量检测和分析的实验方法，它是解决机械工程实际问题的有效途径。所以
