|
摘要
现代科学技术的进步与计算机科学技术的快速发展是分不开的。近几年来,随着计算机制造技术的日益成熟,计算机产业取得了突飞猛进的发展。从国防科技到普通民众生活等各个领域中,计算机得到广泛应用。巨大的需求使计算机产量逐年快速增长,作为计算机系统的重要组成部分,硬盘驱动器的需求量也迅速增长。面对越来越大的市场需求量和越来越高的质量要求,全球各大硬盘生产商都在努力提高生产效率和产品质量。磁头驱动臂组合是硬盘驱动器的重要组成部件,磁头驱动臂的质量是影响磁头驱动臂臂组合性能的关键因素,因此提高磁头驱动臂的质量具有重要意义。本文根据SAE公司实际生产需求,研究设计一台具有自适应功能的磁头驱动臂矫正机,以解决目前公司遇到的问题。
本文首先介绍了磁头驱动臂的工作原理、结构及其需要矫正的关键尺寸:磁头臂高度,然后根据磁头驱动臂的结构特点和材料特性确定对磁头臂高度的矫正方法。按照机械系统设计的一般方法进行总体方案设计:包括机械系统总体方案设计的控制系统总体方案设计。
然后进行整机具体设计,首先进行机械结构具体设计,根据功能要求将整机划分成夹具、工作台、测量机构和矫正机构四大模块进行设计。机械结构设计完成之后,就进行控制系统的设计。控制系统的设计可分为硬件和软件两部分来完成,硬件部分主要任务是控制系统主电气图设计,主控单元的接口进行分配等;软件部分主要任务是控制程序的编写等。
最后应用设计出的磁头臂矫正机进行试验分析工作。首先对一组磁头驱动臂进行手动矫正操作,再对获得的数据进行回归分析,找出磁头驱动臂的变形规律。并将该规律代入控制程序中,然后进行试矫正,检查机器性能是否满足要求。
In modern times, the progress of science and technology is inseparatble with the development of computer science and technology. With the computer manufacturing technology maturing in recent years, the computer industry has achieved rapid development. From the National Defence Science and Technology to the ordinary civilian, and other fields, computers are widely used. The huge demand for the computer leads to the rapid growth of output year by year, and as an important assembly of the computer system, the demand for HDD is increasing accordingly. In face of the increasing markets demand and quality requirement, the world’s major HDD manufacturers are working hard to improve their productivity and product quality. As the hard core assembly of the HDD, HSA’s quality is the key factor that affect the quality of HDD. So there is significance to improve the quality of the access arm. The thesis provides a design and research in arm adjusting machine with adaptive function according to the requirement of SAE Ltd..
The thesis begin with an introduction of the access arm and point out the key dimension of the access arm needs to be adjusted, then decide the djusting plan according to the structure and material property of the access arm. Then carry out overall design including mechanical design and control system design according to the general mechanical designing method.
We began to the specific design after the overall program has been determined. Firstly, the specific mechanical design: the machine was divided into four major modules: fixture, work-table, measuring mechanism and adjusting mechanism, and they were designed separately. Next to the structure designing is control system designing. The control system including the hardware and software. The task of hardware design is to design main electrical circuit and assign the I/O interface of main controller. In other hand the software design is to write control program and etc.
Finally we carry out experiments with the arm adjusting machine, and analysis the test data. Firstly, we adjust the access arm manually, find out the elastic-plastic deforming principle through analyzing the data by the regression method. Secondly, set the control program according to the deforming principle, and check if the performance of the machine meet the requirement.
