【摘要】：在机械制造装备生产行业,柴油机作为制造装备的核心部件,制造装备的生产效率往往在很大程度上取决于柴油机的生产效率。而柴油机的生产效率在很大程度上又取决于柴油机的装配效率。在传统柴油机装配生产线上面,线上工人往往需要人为将大型柴油机频繁进行各种角度的翻转来满足零部件的安装和调试,而柴油机往往笨重且脆弱,为了满足装配质量和生产效率,因此不能完全仅仅依靠人工来进行翻转。而翻转机的诞生,在一定程度上极大的提高了装配质量和生产效率并且大幅度降低了工人的劳动强度,全方位地为社会创造了众多的财富。在柴油机装配工艺过程中,翻转机的目的在于工人在装配环境中能够快速、便利地对发动机进行翻转。在柴油机装配生产作业中往往工作量很大,而且需要频繁的装配和检查,此过程需要翻转机对柴油机进行频繁翻转操作,这就产生了本课题:柴油机装配线非标翻转装置的设计与研究。此项研究工作旨在设计出一台自动翻转机,可以方便、安全的将待装配的柴油机进行翻转,以便提高柴油机装配质量和生产效率,提高经济效益本文在分析了柴油机装配线的特点、装配工艺过程和目前市场上翻转机本身特点的基础上,设计、制造了一种柴油机装配线翻转装置。该装置集机、电于一体,且具有占地面积小、材料损耗低、翻转效率高和安全性能高等优点。结果表明:该装置技术可行、设计合理、动作精确可靠,具有应用推广价值。首先,对柴油机装配线的现状、结构特点、装配工艺过程以及在装配过程国内外现有翻转机特点进行了分析。根据柴油机装配的目标要求,确定了总体方案和方案路线,为该装置的结构设计提供了依据。结合大量文献调研,借助Inventor三维软件,自主设计了一套柴油机装配线非标翻转机装置。该装置包括支撑平台、夹紧装置、三相异步电机及电气控制系统。其次,根据机械装置翻转动作和系统控制要求,从节能角度出发,利用改装新型能量回馈变频器对整个翻转动作进行控制流程设计。包括正反转控制部分,长动和点动控制部分,以保证翻转机装置的运行稳定、可靠,同时达到节能效果。最后,为提高关键零部件刚度、强度、稳定性、使用寿命和轻量化要求,以及补偿零件加工过程的缺陷,使用ANSYS有限元分析软件对装置的关键性零部件进行有限元分析。
[Abstract]:In the machinery manufacturing industry production equipment, diesel engine as the core components of the manufacturing equipment, manufacturing equipment production efficiency often depends largely on the production efficiency of the diesel engine. The diesel engine assembly efficiency and production efficiency depends on the diesel engine. On the machine assembly line of traditional diesel online the workers often need to be artificially large diesel engines frequently for a variety of angles to meet the installation and debugging of turning parts, and diesel engines are often cumbersome and fragile, in order to meet the assembly quality and production efficiency, so can not only rely on artificial to flip. While turning machine was born, to a certain extent, greatly improve the assembly the quality and production efficiency and greatly reduce the labor intensity of the workers, all created many wealth for the society. In the diesel engine assembly process, turning machine The purpose is that workers can quickly in the assembly environment, facilitate the turning to the engine. The diesel engine assembly operation is often a lot of work, but also the need for frequent assembly and inspection, this process needs to be turned for frequent flip operation of diesel engine, which produces the subject: diesel engine assembly line design and Research on the subject of flip device. This research work is to design an automatic turnover machine, can be convenient, safe diesel will be assembled to flip, so as to improve diesel engine assembly quality and production efficiency, improve the economic benefits of the analysis on characteristics of the diesel engine assembly line, basic assembly process and the current market on the flip machine itself characteristics, design, manufacturing a diesel engine assembly line turning device. The device set machine, electricity in one, and has a small footprint, low material loss, flip effect High rate and high safety performance. The results indicate that the device is feasible in technology, reasonable design, accurate and reliable action, has application value. Firstly, the status quo, the diesel engine assembly line structure, assembly process and assembly process in the domestic and foreign existing upender characteristics were analyzed. According to the goal of diesel engine assembly requirements of the overall plan and the plan route is determined, and provides a basis for the structural design of the device. With the extensive literature research, using Inventor 3D software, designed a set of non-standard diesel engine assembly line turning machine device. The device comprises a supporting platform, a clamping device, a three-phase asynchronous motor and electric control system. Secondly, according to the control requirements of mechanical device and flip system, starting from the energy point of view, on the flip of control process design using the modified model. It includes energy feedback converter Inversion of control part, long moving and jog control part, in order to ensure the stable operation of turning machine, reliable, and achieve energy-saving effect. Finally, the key parts to improve the stiffness, strength, stability, life and require the use of lightweight, defect and compensation machining process, using finite element analysis software ANSYS key parts of the device by finite element analysis.
