毕 业 设 计 题 目：步进驱动液压工作台的控制系统设计 摘 要 摆动碾压是汽车轮毂轴承单元铆合装配的一种新兴的压力加工方法，本文在调查研究国内外类似装置的功能、结构、特点和发展应用情况的前提下，结合摆辗技术的基本原理，设计了用于汽车轮毂轴承单元的铆合装配的专用摆碾机床。根据工艺特点，重点研究了该机床的控制系统，设计出合理的控制系统原理图，搭建控制系统平台，设计基于步进驱动液压工作台的控制系统。在本控制系统中，选用AVR单片机作为下位机，单片机作为控制系统的核心，控制步进电机的运转，以实现相应的工艺动作。本文完成控制系统软硬件设计，进行软硬件的调试实验，通过运行调试，该系统成功应用于摆碾旋压设备，运行稳定可靠。 关键词：轮毂轴承单元；铆合装配；步进电机；AVR Abstract Oscillating roller is the automobile hub bearing unit riveting assembly of a new pressure processing method, based on the investigation and study of domestic and foreign similar device function, structure, characteristics and the development of application conditions, combined with the rotary forging technology basic principle, design for automobile wheel hub bearing unit riveting assembly for swinging grinding machine tool. According to process characteristics, focus on the machine tool control system, design a reasonable the principle diagram of control system, building control system design based on the platform, stepping driving hydraulic platform control system. In this control system, using AVR MCU as the next machine, single chip microcomputer as the control core of the system, control of stepper motor running, to achieve the corresponding action. This paper completes the control system hardware and software design, software and hardware debugging experiment, through debugging, the system was successfully applied to a pendulum roller spinning equipment, stable and reliable operation. Key words: hub bearing unit; riveting assembly; stepping motor; AVR 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc323416022 摘 要 PAGEREF _Toc323416022 \h 1 HYPERLINK \l _Toc323416023 Abstract PAGEREF _Toc323416023 \h 2 HYPERLINK \l _Toc323416024 目 录 PAGEREF _Toc323416024 \h 3 HYPERLINK \l _Toc323416025 第一章 绪 论 PAGEREF _Toc323416025 \h 5 HYPERLINK \l _Toc323416026 1.1 引言 PAGEREF _Toc323416026 \h 5 HYPERLINK \l _Toc323416027 1.2 本课题的研究意义与主要任务 PAGEREF _Toc323416027 \h 5 HYPERLINK \l _Toc323416028 1.3 必威体育精装版汽车轮毂轴承铆接工艺应用 PAGEREF
