1、摘 要随着科学技术不断进步,现代化高科技产品向着细小化、智能化、集成化发展,因而微小零件在工业上需求越来越大,和对微小零件的质量要求也不断提高,所以对微小零件的检测方法的探究越来越引起人们的注意。对零件精密测量是现代科技领域最为关键和共性的基础技术之一,在尖端工业生产和科学研究中占有极其重要的地位。其中在微小零件中,螺钉在我们日常生活中应用非常广,几乎所有的机械都有螺钉;螺钉广泛应用于连接、固定等,具有重要的作用,是我们生活、生产中不可缺少的一部分。所以螺钉的质量直接关系到与它相关的产品质量,从而对螺钉的检测就显得越来越重要。光电测量以其非接触、高精度和快速性等特点广泛应用于各种测量。对微小零
2、件的外形尺寸进行光电自动检测,需要对微小零件进行精密定位,其定位精度直接决定了检测精度、检测速度和自动化程度。本文主要研究基于光电开关技术下对螺钉在工作台上的定位,从而实现对螺钉外形尺寸光电自动检测。在本文中,首先,依据零件在工作台上的功能要求,分析情况,选出符合要求的机构方案;接着对所选的方案进行机械系统设计,包括导轨、电机、丝杆、轴承、机械手等选择;最后对系统的控制系统进行分析。关键词:检测;机械设计;步进电机;控制AbstractWith the constant progress of science and technology, modern high-tech products
3、turn towards small, intelligent, integrated development. Therefore, the small parts demand is bigger and bigger in industry, and the quality for small parts is also required to improve constantly. So people take more and more attention to the research of testing method on small parts. Precision meas
4、urement for the parts is one of the key and common foundation technologies in modern science, and it occupies an extremely important position in industrial production and scientific research.Among the small parts,the screw is widely used in our daily life. You can see the screws in almost all the ma
5、chinery. The screw is widely used in connection, fixing and it likes. It is an indispensable part in our life and production. So the screw quality is directly related to the quality of the products associated with it,then the detection for the screw becomes more and more important.Photoelectric meas
6、urement is widely used in all kinds of measurements with its non-contact, high precision and rapidity characteristics. The photoelectric automatic detection for the dimension of small parts needs the precision positioning of tiny parts, and Its positioning accuracy directly determines the detecting
7、precision, speed and the degree of automation.This paper mainly studies the location for the screw on the workbench, which is based on the photoelectric switch technology, so it can realize the photoelectric automatic detection for the screw dimension. In this article, firstly,the institutional prog
