毕业设计（论文）：MG132320-W型采煤机左牵引部机壳的加工工艺规程及数控编程.doc

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发展，减员提效、提高工作面单产成为煤炭发展的主流，发展高产高效工作面势在必行。我国是一个发展中国家，改革开放以来，采煤机研发有了长足的发展，尤其国产电牵引采煤机发展速度很快，应该说跟上了世界采煤机发展的方向。机械设备的先进性、品种、质量、可靠性、适应程度以及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及数控程序的编制。 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 control procedure works out 目 录 摘要 ……………………………………………………………………… Ⅰ Abstract……………………………………………………………………Ⅱ 第一章 绪论 ………………………………………………………………1 第二章 采煤机简介及结构组成 …………………………………………4 2.1 MG132/320-W系列采煤机简介…………………………………4 2.2 采煤机主要特点…………………………………………………4 2.3 采煤机的组成部分及其作用 …………………………………5 2.4 主要技术参数及配套设备 …………………………………… 6 第三章 MG132/320-W型采煤机牵引部箱体的工艺分析 ………………8 3.1采煤机箱体的功用与结构特点 …………………………………8 3.2箱体加工工艺规程分析………………………………………… 9 3.2.1 MG132/320-W牵引部箱体的工艺分析及工艺 规程……………………………………………………… 9 3.2.2 箱体加工误差分析……………………………………… 11 第四章 MG132/320-W牵引部箱体数控加工工艺分析及程序 的编制…………………………………
