摘要

在已经过去的两个世纪里，工业发生了根本性的变化，科技进步对工业的发展产生了前所未有强大动力。而在21世纪里，制造业仍然是影响国民经济发展，提高人民生活水平的支柱产业，在现代化的汽车生产制造业中，基于大批量流水线生产的生产类型，提高生产效率，减低劳动成本，进而提高产品的经济效益成为衡量一个汽车制造商综合竞争力的重要指标。在一条自动化生产线中如果一味利用人力资源进行操作，不仅会浪费不必要的劳动力资源，同时会大大降低整条线的生产效率，这是对厂方利润的大大削减。基于这方面的原因，在生产实际中，常设计不同的机械产品应用于流水线之中，代替人手操作。本课题来源于xxx汽车公司专用设备厂设计一台活塞环装配机，要求将活塞环安全、快捷地装到活塞上，实现活塞环的自动化装配，便于发动机的装配及维修，与发动机的其它生产流水线配套使用，进而提高劳动生产效率，降低生产成本。在课题的设计中，需要完成以下任务：（1）熟悉产品功能，考察相关产品，查阅相关资料，制定2-3种课题总体方案，进行优劣比较，最终选定一种最终方案。（2）根据厂方的实际情况选择动力源，确定传动类型、传动方案，进行数据分析。（3）进行具体零件的设计校核，数据处理。（4）完成图纸的绘制。（5）完成厂方所布置的产品说明书的翻译，整理打印。（6）整理设计资料，完成毕业设计论文。本产品的相关技术说明：活塞环张开时(使得活塞环能装进活塞上，又不至于破坏到活塞环时)，弯板在水平方向上移动的距离；活塞环装配机中曲柄的旋转角度；在活塞环装配机中曲柄滑块机构的具体尺寸；气缸的行程范围及其型号的选择等；最终实现活塞环的全自动装配。经过产品调研并查阅了相关资料我发现，这类产品一般多用于单层生产线，产品精度要求不高，生产环境也没有相关限制，承受的载荷不大，所以在材料的选取上常选用45号钢。

Abstract

In already passed in two centuries, the industry had the fundamental change, the advance in technology has produced the unprecedented formidable power to the industry development. But in the 21st century, the manufacturing industry still affects the national economy development, raises the lives of the people level the pillar industry, in the modernized automobile production manufacturing industry, based on the mass production-runs production type, enhances the production efficiency, decreases the cost of labor, then enhances the product the economic efficiency to become weighs a automobile manufacturer synthesis competitive ability the important target. In a automatic production line if carries on the operation constantly using the human resources, not only can waste the nonessential labor force resources, simultaneously can greatly reduce the entire coarse thread the production efficiency, this is to the factory profit big reduction. Based on this aspect reason, is actual in the production, often designs the different mechanical product to apply in the assembly line , replaces the manpower operation. This topic originates to the car of dongfeng company special equipment factory designs a piston curl assembly machine, requests to be safe the piston curl, quickly to install to the piston on, the realization piston curl automated assembly, is advantageous for the engine assembly and the service, with the engine other production assembly line necessary uses, then the enhancement labor production efficiency, reduces the production cost. Below the topic design, needs to complete the task: (1) the familiar product function, the inspection correlation product, the consult correlation data, formulates 2-3 kind of topic overall plan, carries on the fit and unfit quality comparison, finally designates one kind of final plan. (2) acts according to the factory the actual situation choice power supply, the definite transmission type, the transmission plan, carryon the data analysis. (3) carries on the concrete components the design examination, the data processing. (4) completes the blueprint the plan. (5) completes the product instruction booklet translation which the factory arranges, reorganizes the printing. (6) reorganizes the design material, completes the graduation project paper. This product related technical order that, The piston curl opens when (enables piston curl to load into on piston, when not as for destroys to piston curl), angle iron in horizontal side upward movement distance; In piston curl assembly machine crank degrees rotation; In piston curl assembly machine crank slide organization concrete size; Air cylinder traveling schedule scope and its model choice and so on; Finally realizes piston curl entire automatic assembly. Investigated and studied after the product and consults the correlation data I to discover that, this kind of product was ordinary multipurpose to the single-layer production line, the product precision request is not high, the production environment has not been connected the limit, the withstanding load is not big, therefore often selected 45 steel in the material selection.
Key words: Piston curl assembly; Enhances the production efficiency; Crank degrees rotation <= 45; Entire is automatic
