空調連接板加工工藝與夾具設計（含全套CAD圖紙）,空調,連接,加工,工藝,夾具,設計,全套,cad,圖紙 I 畢 業(yè) 設 計（論 文） 論文題目： 空調連接板加工工藝與夾具設計 專 業(yè)： 年 月 日 II 【摘要】 空調連接板零件零件加工工藝及夾具設計是包括零件加工的工藝設計、工序設計以 及專用夾具的設計三部分。在工藝設計中要首先對零件進行分析，了解零件的工藝再設 計出毛坯的結構，并選擇好零件的加工基準，設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 用夾具的設計，選擇設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生的定位誤差，分析夾具 結構的合理性與不足之處，并在以后設計中注意改進。 關鍵詞 ：工藝，工序，切削用量，夾緊，定位，誤差 Abstract: parts processing technology and fixture design is the design of the process design, including the parts processing process design and the three part special fixture. In the process of design should first of all parts to analyze, understand parts of the process and then design a blank structure, and choose the good parts machining datum, designs the process routes of the parts; then the parts of each step process dimension calculation, the key is to determine the process equipment and cutting the amount of each working procedure; design then a special fixture, fixture for the various components of the design, such as the connecting part positioning device, clamping device, a guide element, clamp and the machine tool and other components; the positioning error generated when calculate fixture positioning, analysis of the rationality and deficiency of fixture structure, pay attention to improving and will design in. Key words: Technology, process, cutting, clamping, positioning III 目 錄 1 緒論
