文档介绍：摘要
在制造行业中回转体工件占有很大的比重,由于内燃机的广泛使用,在国民经济中活塞、气缸套此类回转体工件是占有非常重要的地位,而随着飞速发展的现代工业,传统的回转体检测仪器不能满足高精度在线检测的要求,从而对高效率、高精度的回转体检测仪开发提出了要求,本论文的研究就是在这种情况下开展的。
在检测原理上,本设计的回转体测量仪属于坐标测量,是一种将接触和非接触两种探测技术结合的坐标测量,能很好地满足工业生产提出的快速高精度高效检测的要求,且具有较好的通用性和开放性,并在一定程度上实现了仪器的智能化。
根据回转体的特点,对传统的标准三坐标测量机进行改进,更适合于回转体的检测,并节省了仪器的制造成本;将接触和非接触测量结合,继承两者的优势,使仪器能同时具备快速高效和高精度的优点;建立了以“PMAC+IPC”的双CPU硬件结构为基础的运动控制系统,在与开放性良好的测量软件相结合,使仪器具有良好的开放性;使用各硬件模块搭建完整的运动控制系统,对该系统的参数进行合理的设置与调试;说明了测量软件的设计思想和实现方法。

ABSTRACT
The total production of axisymmetric workpiece has accounted for a large percentage of manufacturing industry. Along with wide application of bustion engine, axsymmetric workpiece such as plunger, cylinder liner has played more and more important role in national economy. With the rapid development of modern industry, the traditional ax isymmetric workpiece detector can fulfills the requirement of on-line detection, ax symmetric workpiece detector of high efficiency and high precision has e the trend of development.
This paper presents a general detecting instrument of axisymmetric body using a coordinate measuring system based on bination of the contact measurement and non-contact measurement. It can fulfill the requirements of industrial production as high precision and on-line detection, and it also has advantages like good generality and openness. Besides these, it is an intelligent instrument to some extent.
According to the characteristics of the axisymmetric body, the traditional and standard CMM is reformed to make this instrument be more suitable for the detection of the axi symmetric body, and to lower manufacturing cost. This instrument inherits advantages of the contact measurement and non-contact measurement, so it has both high and efficiency high precision. It also has good openness and expansibility, because its motion control system is based on a dual CPU posed by PMAC and IPC, and also because its measurement software has good openness. This paper presents
