摘要:汽车大批量零部件的加工都需要组合机床来进行。组合机床以其独特的优点在机械设计中占有重要的地位。它以通用部件为基础,根据工件加工需要,配以少量的专用部件组成的一种机床。它具有低成本,高效率的优点。以现在的发展趋势来看,组合机床的多为加工如果加入柔性系统则发展成今天的加工中心。在当今的发展趋势中,一台组合机床如果不能完成全部的工艺过程,这时往往把几台机床布置流水线,大大缩短了加工时间。

此次在组合机床的设计过程中,对液压系统的主要液压元件如,先导式溢流阀、直动式溢流阀、单向阀、节流阀、截止阀、二位四通换向阀和三位四通换向阀等元件进行选择。主要做了液压方案设计、液压系统主要参数计算、设计结构各执行元件的选择、机床联系尺寸总图、液压系统原理图的作业。完成了机床的液压系统、夹具、送料装置液压系统设计,使其性能更优良、更可靠,提高了其加工效率。提高了其加工精度,行其加工精度的分析和验算,同时分析其强度是否符合加工要求,最大限度的延长其使用寿命。使设计出来的组合机床结构合理、操作方便、更符合用户的要求。

Abstract:Numbers of automobile assembly processed depend on combination machine tools.Combination machine tools to its unique advantage in mechanical design occupies an important position. It is based on general parts processing, according to the needs, with a special components of a machine. It has the advantages of low cost, high efficiency. By now, the development trend of modular machine tool, the more flexible system for processing if join is developing into today's machining center. In today's development tendency, if not a combination machine tools, then all the process of a machine tool layout often pipeline, greatly reducing the processing time.

In the design process of modular machine tool for hydraulic system, the main hydraulic components, such as polot relief valve, e-style relief valve, check valve, throttle valve, cut-off valve, two, three and four directional valve spool reversing valve elements such as selection. The major hydraulic design, the main parameters of hydraulic system design calculation, the choice of components and machine, hydraulic system connection size layout principle chart. Complete machine, hydraulic system and hydraulic system of feeding device fixture design, make its superior performance, reliable, improve the machining efficiency. Improve the machining accuracy, the machining accuracy of analysis and calculation, and analyzes its strength meets the requirements of the processing, the maximum prolong its service life. Make the combination machine tools reasonable structure, convenient operation, conforms to the requirements of the customers.
