摘要 随着工业技术的不断发展，液压和气压传动的范围也越来越广范，而作为液压和气压传动系统心脏的液压泵和气压泵就显得更加重要了。在容积式气压泵中，只有柱塞泵是实现高压化﹑高速化﹑大流量的一种最理想的结构，轴向柱塞泵结构紧凑，径向尺寸小，故传动效率高；另外，轴向柱塞泵易于变量，能用多种方式调节流量，流量大。由于上述特点，轴向柱塞泵被广泛用于工程机械、起重运输、冶金、船舶等多种领域。航空上，普遍用于飞机液压系统、操纵系统及航空发动机燃油系统中。手摇式柱塞泵由于结构紧凑、使用方便、便于携带，被广泛用于工业和人民生活的多个领域。 文中通过对给定的压强条件的分析，设计了一款手摇式柱塞泵。本柱塞泵设计为双泵体、双出入口的形式，可以完成连续运动，此次设计包括把、柱塞、柱塞缸、阀体及联板的结构设计及计算、把、柱塞、柱塞缸、阀体及联板的机械加工工艺规程设计、CAD零件图和装配图及三维造型设计等。 运用所学的机械设计知识，通过对柱塞缸的强度计算、柱塞的截面应力分析、螺栓的剪切引力计算及手摇泵自由度分析等多种理论力学和材料力学的计算及分析，设计了手摇泵的总体装配结构。在满足强度条件的基础上，完成了最终的装配结构设计和各零件的结构设计。 运用所学的机械制造知识，对手摇式柱塞泵的所有的非标准件进行了机械加工工艺规程的设计。并运用Pro/E软件实现了三维数字化造型设计。 关键词 手摇泵,设计,制造,Pro/E Abstract With the continuous development of industrial technology,?the range of?hydraulic and pneumatic?transmission?is more and?more widely,?and as the?hydraulic and pneumatic transmission system of heart?of hydraulic pump and?pneumatic pumpbecomes more and more important.?The?volume of?air pressure pump,?only theplunger pump?is an?ideal?structure of?high pressure,?high speed,?large flow?axial plunger pump,?the structure?is compact,?small radial dimension,?so?the transmission efficiency is high;?in addition,?the variable?axial piston pump?is easy,can adjust the flow?in a variety of ways,?large flow.?Because of the above characteristics,?axial piston?pump is widely?used in engineering machinery,?lifting transport,?metallurgy, shipbuilding?and other fields.?Widely used in?aviation,aircraft hydraulic system, control system and fuel system of aviation engine.?The hand-operated?plunger?pump because of?the advantages of compact structure,convenient use,?easy to carry,?is widely used in many?fields of?industry and peoples?life.
