MG132320-W 型 采 煤 左 牵 引 部 机 壳 的 加 工工 艺 规 程 与 数 控 编 程 ( 论 文 +DWG 图 纸 )摘 要采煤机直接用于煤炭的地下开采，是煤炭生产中最重要的机械设备之一。进入20世纪90 年代后，随着煤炭生产向集约化方向进展，减员提效、提高工作面单产成为煤炭进展的主流，进展高产高效工作面势在必行。我国是一个进展中国家，改革开放以来，采煤机研发有了长足的进展，尤其国产电牵引采煤机进展速度很快，应该说跟上了世界采煤机进展的方向。机械设备的先进性、品种、质量、可靠性、适应程度以与寿命是衡量一个采煤国家的采煤机技术水平的标准。本次设计的主要任务是对MG132/320-W 型采煤机左牵引部机壳进行加工工艺规程设计以与数控程序的编制。关键字： 采煤机 加工工艺规程 数控程序编制Abstract :Exploit in the mining machine underground used in the coal directly, it is one of the most important mechanical equipment in production on the coal. After entering 1990s, as coal production was developed toward intensification, cut personnel result of proposing , raise working range per unit area yield become coal mainstream of development, it is imperative to develop the high-efficient working range of high yield. Our country is a developing country, since reform and opening-up, the mining machine has researched and developed and got considerable development, domestic electricity draw person who mine develop very fast , should catch up with world direction of development of mining etc. especially. Advance , variety , quality , dependability of mechanical equipment,, intensity of meeting and life-span to weigh one mine coal mining machine standard of engineering level of country.The main task that design chassis carry on preparation method rules design and numerical control establishment of procedure to MG132/320-W left person who draw of mining etc.Key word:Mining machine Rules of preparation method The numerical contr...
