摘要：电磁检测又称无损检测是一种利用声、光、磁和电的特性，在不损害或不影响被检对象使用性能的前提下，检测被检对象中是否存在缺陷或不均匀性，给出缺陷的大小、位置、性质和数量等信息，进而判定被检对象所处技术状态（如合格与否、剩余寿命等）的所有技术手段的总称。35492
近几年来，中国机械制造业的产品数量已经位居世界前列，但主要是劳动密集型产品，具有自主知识产权的高、精、尖产品比较少，随着微电子技术、微处理器技术、信息技术和材料技术飞速发展并不断变革，检测技术也随之有了脱胎换骨的变化，因此把电磁检测技术应用到机械零件的检测当中去就成了迫在眉睫的任务。现有的检测装置多用人为控制检测探头移动，移动检测探头检测时不能很好的定位，容易带来较大误差，且增加检测人员不必要的工作量。为了简化操作过程，减少测量人员的工作量，最大限度的提高检测精度和数据可信度，设计了本课题的装置。

Design of electromagnetic auto detection device for surface defects of shaft parts
Abstract：TDetection of electromagnetic nondestructive testing is a use of acoustic, optical, magnetic and electrical properties in does not damage or does not affect the detection performance under the premise, examine the inspection and Quarantine of whether there is a defective or uneven, to show the defect size, location, nature and quantity of such information, and then determine the inspection object technology (such as qualified or not, the residual life of) all the technology in general.
In recent years, the number of products machinery manufacturing industry in China has been ranked in the forefront of the world, but mainly labor-intensive products, with independent intellectual property rights of the high, precise, sharp products is relatively small, with microelectronics technology, microprocessor technology, information technology and materials technology rapid development and change ceaselessly, detection technology also immediately thoroughly remould oneself change, so the detection of electromagnetic detection technology is applied to mechanical parts to become an urgent task. Artificial control detection probe moving with the current detection device, positioning mobile detection probe detection is not very good, easy to bring large error and increase the workload of inspectors is not necessary. In order to simplify the operation process, reduce the workload of the measuring staff, improve the detection accuracy and data credibility, and design the device of this research..
