62米长臂架混凝土泵车6#臂架油缸的设计 摘要 本文对臂架液压缸进行结构和参数的设计，建立液压缸三维模型，并投影出二维工程图纸。液压缸结构相对简单，运行起来比较可靠，且生产制造也容易以及使用维护方便、低速稳定性好等优点；作为液压执行元件，既能实现往复运动又可以实现小于360°的回摆运动。因此，在工业生产制造各个部门中得到广泛应用，长臂架泵车的输送装置中也不例外。所以，设计液压缸的参数以及对结构的改进，提高各种性能对于更好地提高臂架泵车工作的效率具有非同凡响的意义。 基于本课题的设计要求，首先我查阅了很多相关的资料，对臂架泵车的整体结构有了初步的了解，然后进一步了解了臂架的伸缩臂结构。伸缩臂是泵车输送装置的重要部件，而伸缩臂大都是用液压缸作为动力元件，因此，液压缸的结构和参数决定整个泵车的工作性能。所以接下来就是对液压缸的结构进行方案设计，通过查阅机械设计手册、油缸设计规范（企业标准）、新编液压手册以及相关书籍并结合实际案例和生产规范，最终确定优化方案。然后根据液压设计时给定的参数，运用设计手册的计算方法，结合生产制造的实际，得到整个油缸的参数。最后用三维SolidWorks软件画出油缸的整体结构并进行三维模型的仿真与优化，确保结构和参数的可靠性后导出二维工程图，转成CAD格式，对二维图进行标注，完成毕业论文说明书。 关键词：油缸、液压缸、臂架、混凝土泵车 The design of 62 meters long arm frame of concrete pump truck boom cylinder 6# Abstract In this paper, the boom of the hydraulic cylinder in the design of the structure and parameters, to establish 3 d model of the hydraulic cylinder and the projection of 2 d engineering drawings. Because the hydraulic cylinder structure is relatively complex, to run more reliable, and manufacturing also easy and convenient in operation and maintenance, as well as good stability at low speed. As the hydraulic actuators, both can realize reciprocating motion and can achieve less than 360 ° back swing motion. Therefore, is widely applied in industrial production in the various departments, the long boom pump truck conveyer is no exception. So, design the parameters of the hydraulic cylinder as well as to the improvement of the structure, improve various performance for better improve the efficiency of the car boom pump work has the remarkable significance. Based on the design requirements of this topic, first of all, I looked at a lot of relevant information, to the overall structure of the car boom pump have a preliminary understanding, then learn more about the telescopic crane boom structure. Telescopic boom is an important part of a pneumatic conveying pump truck, and telescopic boom are mostly made with the hydraulic cylinder as power components, therefore, the structure and parameters of the hydraulic
