电冰箱升降平台设计 摘 要 电冰箱是现代人们生活必需的家用电器，和大部分的工业产品一样，在批量化生产的过程中，电冰箱的制造也是流水线的。一般的工业产品在生产中必须保证一道工序向下一道工序的转移连接，然而生产活动常常局限于生产场地、技术要求以及装配工艺等各种条件的限制，这一系列的问题促使人们不断完善现代流水制造业产品线的机械化、自动化甚至智能化。比如当对某一产品生产时在不同工序段有不同高度要求时，人们引入了“升降设备”，本设计就是针对于电冰箱生产线的升降环节展开一系列设计。对于一种机械设备的设计而言，首先必须了解产品的作用和意义，因此对市场要有必要的调查和了解，比如常用电冰箱的尺寸、重量以及材料种类，同时要切合实际地考察企业的产能要求、生产节拍和劳动效率。进而对应列出出合理尺寸以及工作条件的“升降设备”初步要求，以此为本设计的大纲。按照此要求，通过机械原理设计，一一进行草图绘制、运动分析、力学校核，结合生产生活实际选择出最优的方案。以此为蓝本再进行CAD图纸制作，材料确定以及动力确定。在整个设计的过程中，可以通过生活工作实践，总结改进方案，尽可能将最终成果最优化。 关键词：流水线 升降设备 设计 Design of refrigerator lifting platform Abstract：Refrigerator is the modern people living necessary household appliances, like most of the industrial products, in the process of mass production, refrigerator manufacturing and assembly line. General industrial products must ensure that the procedure in production procedure, the transfer of the down connection, but production activities are often limited to the production site, technical requirements as well as the assembly process and so on various constraints, this a series of problems, people constantly improve mechanization, automation and intelligence of modern water manufacturing product line. Such as when a product production in different processes with different height requirements, people lifting equipment is introduced, the design is in the refrigerator production line of the elevator link launched a series of design. For a kind of mechanical equipment design, must first understand the function and significance of the product, so the market should have the necessary investigation and understanding, such as common refrigerator size, weight and material types, at the same time to practical studies on enterprise capacity requirements, production rhythm and labor efficiency. Thus corresponding to list out the reasonable size and working conditions for lifting equipment preliminary requirements, in order for this design outline. According to this requirement, through the principle of mechanical design, sketch map, m
