M万能工具磨床座体零件的加工工艺.docVIP

摘要 论文真对M6025万能工具磨床座体零件的加工工艺规程及一些工序的专用夹具设计。零件在工作中起连接作用，加工刀具这样的工件时需要多角度加工，转盘连接工件和机床可实现工件多方位转动，零件通过孔和面与机床和工件连接，所以对孔和两个旋转面的位置精度要求和尺寸精度要求比较高。设计要求一天８小时工作制，一个月生产3000件，设备主要是以普通机床为主（通用机床、专用夹具、通用量具为主、部份工序可采用数控机床、专用量具），零件初加工过后要求人工时效。通过对零件的结构和作用的分析，本论文将制定一个详细的中批量生产的工艺规程，和一个专用车床夹具和一个专用钻床夹具的设计过程，还要把所以有工序的工序卡片填好，为了满足要求我决定采用流水作业来提高效 率，所有的机床都采用普通机床，夹具采用专用夹具，量具采用通用量具。 关键字：转盘，工艺规程，专用夹具。 Abstract True paper dial on the M6025 universal tool grinder parts process planning and some dedicated fixture design process.The connecting part in the work role, such a workpiece processing tool requires multi-angle processing,Connect the workpiece and machine tool rotary table can realize multi-directional rotating workpiece , Part through the hole and connected surface and the machine tool and workpiece ,So the holes and the location of the two rotating plane precision and dimensional accuracy requirements are relatively high. Design requirements for 8-hour day, a month 3000 production, equipment, general machine tools mainly based (universal machine tools, special fixtures, general measuring the main part of the process can be used CNC machine tools, special measuring tools) ,After initial processing requirements of parts artificial aging .Through parts of the structure and function, this thesis will develop a detailed process in the production of order, and a dedicated lathe and a special drill jig fixture design process, but also to process the card so the process completed, in order to I decided to use assembly-line to meet the requirements to improve efficiency, all the machines are using ordinary machine tools, fixtures use special fixtures, gauges using a common measuring tool. Keywords: dial, process planning, special fixtures. 绪论 毕业设计是学生在完成在校期间的基础课以及全部专业课之后进行的一次考核，考查学生是否具有能力去完成一项与专业相关或与专业无关的任务，这就要考查学生有没有具备独力学习、合作、独力思考的能力，这也是大学生该具备的能力，所以毕业设计是对学生综合能力的一次大考验，也是学生能否合格拿到毕业证的标准。 机械加工工艺分析及夹具设计是数控专业非常重要的两门课程，它详述了零件从材料到成品全过程，，加工工艺是工人进行加工的一个依据，所有零件只有制定合理的工艺才能加工出合格的零件来，夹具就是让工件在机械加工时和机床保持正确的位置
