设计简介
摘 要
弹簧的应用十分广泛可以说是各种机械、电器 、化工等产品的关键零件。凡是承受变载荷的弹簧，在企业内部质量控制、用户交验、新产品定型鉴定、认证，行业抽检和工艺调整环节中，必须进行性能检测。所以弹簧检测是其生产过程必不可少的工序，测力是检测的主要内容之一。弹簧测力分选机是在基于工业进程高速发展的今天，结合圆柱螺旋弹簧的需求量和生产企业需求的前提下所应运而生的。本论文主要是对分选机的机械结构进行研究,设计，实验与制造。此弹簧分选机是针对大批量生产的弹簧依据其弹性系数不同，按照预先规定的指标进行测试自动筛选出合格与不合格产品，并在不合格产品范围内依据是否可以修复将弹簧进一步细分，自动流入不同料箱，以此应用与不同场合。这种弹簧分选机是安装在弹簧加工过程中的检测工艺工段线上，针对汽车、摩托车离合器弹簧生产制造工艺设计的，适用于各种类型的圆柱螺旋弹簧的分选。
本论文首先论述螺旋弹簧分选机的分选方式以及国内外分选机的研究现状和设备的性能优缺点，结合课题背景，提出本论文的主要研究内容。在对弹簧特点与控制需求进行分析的基础上，提出了分选机机械结构的方案设计。
在论文中所研究和设计的圆柱螺旋弹簧分选机，满足功能要求，解决了弹簧生产过程中的实际问题，提高了生产与检测效率，为以后此类设备的设计提供了借鉴作用。

Abstract
Spring testing is the phase of the production process essential working procedure, load is one of the main content of detection. Spring load separator is in today's rapid development based on industrial process, in combination with the demand and production of cylindrical helical spring under the premise of enterprise requirements arises at the historic moment. This thesis mainly is the study of mechanical structure of the separator, the design, the experiments and manufacture.This spring sorting machine is for mass production according to the elastic coefficient of the spring, in accordance with the prescribed index test automatically select the qualified and unqualified products, and within the scope of the unqualified products according to whether can repair will spring further subdivided, automatic into the different material box, with different situations in application. The spring separator is installed in the spring section of online detection technology, in the process of machining for automobile, motorcycle clutch spring manufacturing process design, suitable for various types of cylindrical helical spring sorting.
This paper first expounds the separation method of helical spring sorting machine and the performance of the domestic and foreign research situation of the separator and equipment advantages and disadvantages, combined with the project background, puts forward the main research content of this paper. On the analysis of the demand and control characteristics of the spring, on the basis of sorting machine mechanical structure design are put forward.
In the thesis the research and design of cylindrical helical spring sorting machine, meet the functional requirements, solved the practical problems in the process of producing spring, improve the efficiency of the production and testing, design provides a reference for such a facility.
Keywords: Cylindrical helical spring; separator; Modulus of elasticity
