492Q型气缸盖双端面铣削 组合铣床总体设计 摘 要 组合机床是以系列化、标准化的通用部件为基础，配以少量专用部件组成的专用机床。它适宜于在大批、大量生产中对一种或几种类似零件的一道或几道工序进行加工。组合机床可以对工件进行多面、多主轴加工，一般是半自动的。 本设计就是组合铣床的设计。其主要用在生产线上加工汽车的气缸盖的两端面。适合大批量的生产。 本设计中采用液压传动控制,在结构上要巧妙完成动作协调。用液压系统来提供动力,进而减少工作量,提高效率,也能减少人员损伤。 关键词： 组合铣床 气缸盖 液压系统 Abstract Combine the tool machine is an in general use parts that turn, standardizes with the series for the foundation, going together with with the appropriation tool machine that a little amount appropriation parts constitute.It is feat in in large quantity, mass production to a kind of or several category an or a few work preface of the spare parts carries on process.Combine the tool machine can carry on to the work piece to face much, many principal axises process, is a half generally automatic. This design is a design to combine the machine bed. Its use primarily in the production on-line process the both ends of the automotive cylinder cover. In keeping with the production that large quantity measures. The origin designs the medium adoption liquid to press to spread to move the control, wanting that the handiness completes the action on the structure coordination.Presses the system to provide the motive with the liquid, then reduce the workload, lift high-efficiency, also can reduce the personnel to hurt. Key words: Combination machine bed The cylinder covers The system of hydraulic pressure 目 录 引 言 4 1明确任务书，分析原始资料 6 1.1被加工工件的零件图............................................... 6 1.2明确任务书 7 1.3分析原始资料 7 2 组合机床方案的制定 7 2．1 组合机床设计概述 7 2.1.1 组合机床的特点 8 2.1.2 组合机床的分类 8 2.1.3 组合机床发展方向 8 2.1.4 组合机床设计步骤： 9 2.2 确定工艺方案 10 2.3确定机床配置形式及结构方案 10 2.3.1 配置型式的确定 10 2.3.2 结构方案确定 10 3 确定切削用量及选择刀具 11 3.1选择刀具 11 3.2工序余量的确定 12 3.3确定切削用量 12 3.4计算铣削力，切削扭矩，切削功率 13 4 组合铣床总体设计 13 4.1零件工序图 13 4.2加工示意图 14 4.3 动力部件的选择 14 4.4 机床生产率计算 15 4.5机床联系尺寸图的绘制 16 5 液压系统的设计 17 5.1明确系统设计要求 17 5.2分析工况确定主要参数 17 5.2.1负载阻力分析： 17 5.2.2绘制负载图、速度图： 19 5.2.3初步确定液压缸参数： 19 5.3拟订液压系统图 23 5.4计算选择液压元件 27 结 论 29 致 谢 30 参 考 文 献 31 492Q型气缸盖双端面铣削 组合铣床总体设计
