【正文】 在整整一學(xué)期的日子里，可以說學(xué)到了很多很多的的東西，同時鞏固了以前所學(xué)過的知識，而且學(xué)到了很多在書本上所沒有學(xué)到過的知識。通過這次畢業(yè)設(shè)計使我懂得了理論與實際相結(jié)合的重要性，只有理論知識是遠遠不夠的，只有把所學(xué)的理論知識與實踐相結(jié)合起來，再從實踐中總結(jié)經(jīng)驗才是真正的實用，才能運用到生產(chǎn)實踐中。在設(shè)計的過程中遇到了許多問題，當(dāng)然也發(fā)現(xiàn)了自己的不足之處，對以前所學(xué)過的知識理解得不夠深刻，掌握得不夠牢固，通過這次畢業(yè)設(shè)計，讓自己把以前所學(xué)過的知識重新復(fù)習(xí)了一遍。這次畢業(yè)設(shè)計雖然順利完成了，也解決了許多問題，也碰到了許多問題，老師的辛勤指導(dǎo)下都迎刃而解。同時，在老師的身上我也學(xué)得到很多額外的知識，在此我表示深深的感謝！同時，對給過我?guī)椭耐瑢W(xué)和老師再次表示忠心的感謝！致謝此次設(shè)計是在指導(dǎo)教師許偉老師的細心幫助，耐心講解下完成的，非常感謝許老師的大力幫助，在此次設(shè)計過程中深刻的體會到了許老師那種平易近人，熱心助人的待人的樂人精神同時也讓我感到那種嚴謹細致的工作態(tài)度。很多時候老師會給我一些很獨特的想法使我的在設(shè)計中更加大膽的發(fā)散自己的思維，充實自己的設(shè)計過程，豐富此次的設(shè)計結(jié)果，在這里再次感謝許老師。當(dāng)然在這里還要感謝大學(xué)四年所有帶過我課的老師，是你們讓我的大學(xué)生活更加的豐富伴有科學(xué)文化知識，也是為本次設(shè)計的成功鋪下的前期準備，在此，感激之情不言于表更銘記在心。再次感謝上述所有人的支持和關(guān)懷與幫助！參考文獻1 《機械制造工藝學(xué)》.常同立，楊家武，佟志忠編著. 清華大學(xué)出版社2 《機械制造工藝學(xué)與機床夾具設(shè)計》課程設(shè)計指導(dǎo)書，設(shè)計范例，3 《機械制圖》.第6版. 大連理工大學(xué)機械工程圖學(xué)教研室編. 高等教育出版社4 《機械設(shè)計》.第8版. 5 《公差與測量技術(shù)》.6 《材料力學(xué)Ⅰ》.第5版. 7 《用量簡明手冊》. 8 《夾具設(shè)計手冊》. 9 《English in Mechanical and Electrical Engineering》 趙運才、 Title The design of the mechanical processing procedures and fixture of the tray of machineAbstractMachining process is in the process of production by changing raw object shape, location and nature of each other, make it bee the finished product or semifinished product improvement process, to realize the economic saving production purpose.This topic research fly hammer bracket processing procedures, through the formulation reasonable machining technology to improve the shape of the object, the location and nature of each other to achieve the purpose of the economical production. First analyze the part drawing and the working process of the ponent performance, understand the workpiece concrete structure forms, clarify the technical requirement and to choose the right parts surface processing method. Second to formulate reasonable processing procedures. In machine tool fixture design, to ensure that the workpiece positioning in machine tool and fixture and clamping of the firm, the workpiece and cutting tool and machine tool spindle and slideway between has the correct relative position, so as to ensure the accuracy of the processed workpiece size, shape, position precision and accuracy。 After the workpiece positioning should be fixed in the right position, so that it is not because of a variety of external force and change its relative position changes. During the design process by looking up and collecting relevant materials and data, reading and studying relevant materials, with the help of AutoCAD 2 d design software in graphic design fixture by using the SolidWorks 3 d design software to realize the threedimensional modelling of fixture design. Emphatically studied the parts processing, fixture, the shape of the structure and ponents of positioning, clamping on the drill jig.Keywords mechanical techniques the design of clamprough machining allowance mechanical processing procedures
