【正文】 設(shè)計說明書 題目 軸 的加工工藝及銑鍵槽夾具設(shè)計 班 級： 姓 名： 指導教師： 完成日期： 摘 要 本次設(shè)計內(nèi)容涉及了機械制造工藝及機床夾具設(shè)計、金屬切削機床、公差配合與測量等多方面的知識。 全套圖紙，加 153893706 軸 零件的工藝規(guī)程及 銑鍵槽的 夾具設(shè)計 是包括零件加工的工藝設(shè)計、工序設(shè)計以及專用夾具的設(shè)計三部分。在工藝設(shè)計中要首先對零件進行分析，了解零件的工藝再設(shè)計出毛坯的結(jié)構(gòu)，并選擇好零件的加工基準，設(shè)計出零件的工藝路線；接著對零件各個工步的工序進行尺寸計算，關(guān)鍵是決定出各個工序的工藝裝備及切削用量；然 后進行專用夾具的設(shè)計，選擇設(shè)計出夾具的各個組成部件，如定位元件、夾緊元件、引導元件、夾具體與機床的連接部件以及其它部件；計算出夾具定位時產(chǎn)生的定位誤差，分析夾具結(jié)構(gòu)的合理性與不足之處，并在以后設(shè)計中注意改進。 關(guān)鍵詞 ：工藝、工序、切削用量、夾緊、定位、誤差。 ABSTRCT This design content has invo lved the machine manufacture craft and the engine bed jig design, the metalcutting machine tool, the mon difference coordination and the survey and so on the various knowledge. The reduction gear box body ponents techno logical process and its the processing ho le jig des ign is inc ludes the ponents processing the techno logic al des ign, the working procedure des ign as well as the unit clamp design three parts. Must first carry on the analys is in the techno logic al design to the ponents, understood the ponents the craft redes igns the semi finished materials the structure, and chooses the good ponents the processing datum, designs the ponents the craft route。 After that is carrying on the size putatio n to a ponents each labor step of working procedure, the key is decides each working procedure the craft equip ment and the cutting spec ifications。 Then carries on the unit c lamp the des ign, the choice des igns the jig each position part, like locates the part, c lamps the part, guid es the part, to clamp concrete and the engine bed connection part as well as other parts。 Positio n error which calculates the jig locates when produces, analyzes the jig structure the ratio nality and the defic iency, and will design in later pays attention to the improvement. Keywords: The craft, the working procedure, the cutting spec ific atio ns, clamp, the localization, the error. 目 錄 序言 …………… ………………………………………… .1 1. 零件分析 … ……… ……………………………… ..2 零件作用 …………… ……………………… .2 零件的材料分析 ………………… …
