Abstract: The machining of inner bore of king sized cylinder block is a kind of problem often encountered in machining. In order to solve the problem of machining the inner bore of king sized cylinder block by using a normal lathe, this paper introduces the installation of a tooling in ordinary lathe to effectively solve the machining of the inner bore of king sized cylinder block on board of a ship. During the design of tooling, the vibration of cutter rod is the key factor. A sliding supporting copper bush and a holder will be provided for the cutter rod, and the vibration of the cutter rod can be effectively solved by adjusting the supporting point of the cutter rod during the machining, so as to improve the machining quality of the king sized hydraulic cylinder block.
Key Words: Machining; Processing workmanship; Lathe tooling; Machining of king sized cylinder block
客滚船艏艉门的开闭油缸、坡道的升降油缸、货船液压舱盖的开闭油缸等,都是超长液压油缸,其油缸加工质量直接影响到船员和乘客的生命安全。超长油缸体内孔加工是机械加工中难度系数较高的一种,通常工人需要借助其他机器辅助完成,即使这样,这也是一个十分复杂精密的过程。传统常规加工方法是采用一端悬空长刀杆进行加工,加工过程中刀杆容易发生振动现象,影响加工质量[1-4]。
该文介绍一种利用普通车床安装工装进行超长油缸体加工的方法,能够有效地解决该加工难题。
1 工件特点分析
分析油缸体工件的结构特点:工件属于薄壁深孔加工,自身刚性差,用传统加工法,刀杆细长易振动,易产生报废现象,需使用特殊附件和工装才能达到工件精度要求。
2 加工方案、工裝设计及制作
根据工件特点,结合公司设备情况,了解工件的加工难度,选择合适的加工设备。……
