【摘要】：螺母作为机械设备主要连接零部件之一,依靠其优秀的机械特性,广泛的应用于各类机械设备中。因此对螺母使用性能进行检测显得尤为重要。对目前螺纹检测设备进行调查研究,发现存在检测效率低、检测成本高等问题,难以满足螺母出口企业的批量全检要求。因此有必要研制一台适用性强、效率高、成本低的螺母内螺纹检测设备。首先,根据选定的接触式综合测量法以及制定的设备技术指标,本文提出立式螺母内螺纹检测机的总体设计方案,采用模块化思想将设计方案分为机架总成、检测平台总成和螺母移动定位总成等,对各组成部分进行设计计算,验证设计合理性。样机完成后进行样机实验,对实验数据进行分析总结。针对实验过程中出现的问题提出解决方案,并对立式螺母内螺纹检测机设计方案进行总结。然后,针对立式螺母内螺纹检测机实验后出现的问题,提出卧式螺母内螺纹检测机的总体设计方案。采用模块化思想将设计方案分为机架总成、移动总成、检测平台总成、上料总成和分拣总成等,并对主要零部件进行设计与选型计算。其中设计的双向导杆式离合器通过与齿轮结构配合,实现一个伺服电机同时控制四个检测工位。最后,为验证设计方案的可靠性和安全性,对设备进行建模和虚拟装配,并对重要的零件进行有限元分析。同时参与完成卧式螺母内螺纹检测机控制系统的需求分析、方案设计、工作流程制定等工作。
[Abstract]:As one of the main parts of the mechanical equipment, nut is widely used in all kinds of mechanical equipment depending on its excellent mechanical properties. Therefore, it is very important to detect the performance of nuts. Investigation and Research on the current thread detection equipment have found that there is a low detection efficiency and high detection cost, and it is difficult to meet the nut. Therefore, it is necessary to develop a screw thread testing equipment with strong applicability, high efficiency and low cost. First, according to the selected contact comprehensive measurement method and the set of equipment technical indexes, the overall design scheme of the vertical nut internal thread testing machine is proposed in this paper, and the design of the modular idea will be adopted. The scheme is divided into the frame assembly, the detection platform assembly and the nut moving and positioning assembly. The design and calculation of the components are designed to verify the rationality of the design. After the prototype is completed, the prototype experiment is carried out and the experimental data are analyzed and summarized. The solutions are proposed for the problems in the experimental process, and the vertical nut inner thread testing machine is designed. The scheme is summarized. Then, in view of the problems of the vertical nut inner thread testing machine, the overall design scheme of the horizontal nut internal thread testing machine is proposed. The design scheme is divided into the frame assembly, the mobile assembly, the inspection platform assembly, the assembly and the sorting assembly, and the design and design of the main parts and components. The two-way guide rod clutch is designed to realize a servo motor and control four detection stations at the same time by cooperating with the gear structure. Finally, in order to verify the reliability and safety of the design scheme, the equipment is modeled and assembled, and the important parts are analyzed by finite element analysis. Meanwhile, the horizontal nut is completed. Requirements analysis, program design, workflow formulation of internal thread detecting machine control system.
