阀体双面卧式专用机床设计 摘 要 应用组合机床加工大批量零件，快捷高效，生产效率高是机械加工的发展方向。本次设计任务是：阀体双面卧式组合钻床及主轴箱设计。设计过程主要阐述了组合钻床的工作原理，设计过程，与通用机床和普通专用机床相比的优越性，并对其主轴箱进行设计和计算。本课题设计的基本任务是完成机械部分的设计，主要有被加工零件的工序图、加工示意图、机床联系尺寸图、主轴箱装配图，以及重要零件的绘制。 在设计过程中根据实际情况取得相关数据，参考有关资料，吸取前人的设计经验，并根据客观实际和掌握的现有知识进行改进。 主轴箱是组合机床的主要部件之一，按专业要求进行设计，由通用部件组成。其主要作用是：根据被加工零件的加工要求安排各主轴位置，并将动力与运动由电机或动力部件传给各工作主轴，使之得到要求的转速和转向。 关键词：阀体，组合钻床，主轴箱 Body double horizontal special machine tool design ABSTRACT Application of combination of machining parts in large quantities, fast and efficient, high productivity is machining direction. The design task is: pump body of gear pump connection hole drilling machine and spindle box mix design. The design process focused on the combination of drilling the working principle of the design process, and general machine tool and general compared to the advantages of a dedicated machine, and the spindle box design and calculation. The subjects basic task is to design the mechanical parts to complete the design, the main parts of the process by processing maps, schematic processing, machine tools Contact size map, spindle box assembly, as well as important parts of the drawing. During the design process, the actual situation in accordance with relevant data, reference information, learn from previous design experience, and based on objective reality and, if available, to improve existing knowledge. Combination of machine tool spindle box is one of the main components, designed by professional requirements, from general-purpose components. Its main role is to: be processed in accordance with the processing requirements of parts arranged for the main location, and power and exercise power from the motor or the working parts to the main axis, so that it can be the requirements of speed and steering.
