According to the characteristics of itself, production parts and parts in the specific work type the role of selection process planning and fixtures. In the process planning aspects: based on the research of the ordinary lathe tool central wheel and the process parameters to take a optimization strategy, developed a good turntable. So as to shorten the production cycle, reduce manufacturing costs and improve machining precision and extend the life of cutter, and based on the optimization of process parameters and tools. Can establish or perfect process database high-speed cutting, cutting process will accumulate in practice the reasonable selection of cutting parameters of the tool and the experience and data collected, and the processing to provide accurate and optimization of high speed cutting data, more degree increase cutting processing level and get more economic interests；The fixture design, because it is dish parts processing, two side, choice of vertical milling machine, so considering many factors draw up the optimum scheme: reduce the processing of prime time and auxiliary time, improve labor productivity, reduce labor intensity, finally complete the design. Key words: turntable；Making up the process of machine workmanship；Special jig design 目 錄 摘 要 I Abstract II 第1章 緒論 1 1.1 現(xiàn)代機(jī)床夾具國內(nèi)外發(fā)展概況 1 1.1.1 國內(nèi)發(fā)展概況 1 1.1.2 國外發(fā)展概況 2 1.2 CA6140普通車床刀架中部轉(zhuǎn)盤概述 3 1.2.1 轉(zhuǎn)盤的用途 3 1.2.2 轉(zhuǎn)盤的技術(shù)要求 4 1.2.3 轉(zhuǎn)盤的工藝性 4 1.2.4 轉(zhuǎn)盤的生產(chǎn)類型確定 4 第2章 轉(zhuǎn)盤機(jī)械加工工藝規(guī)程設(shè)計(jì) 6 2.1 分析零件圖 6 2.1.1 零件的作用 6 2.1.2 零件的工藝分析 6 2.2 選擇毛坯制造形式 6 2.3 擬定工藝路線 7 2.3.1 劃分加工階段 7 2.3.2 選擇基準(zhǔn) 7 2.3.3 確定加工方案 8 2.4 確定加工余量及工序尺寸 9 2.4.1 確定各表面的加工余量 9 2.5 確定切削用量及工時(shí)定額 11 2.5.1 銑燕尾面A、B及D面、空刀面F 11 2.5.2 銑尺寸237.5兩側(cè)面Q 16 2.5.3 車Φ70h6外圓面N，端面，倒角，Φ186外圓，端面D 17 2.5.4 鉆、擴(kuò)、鉸Φ35H7孔，鉆2×Φ13孔 25 2.5.5 銑斜面E，磨燕尾面 28 第3章 銑床夾具設(shè)計(jì) 31 3.1 問題的提出 31 3.2 夾具設(shè)計(jì) 31 3.2.1 定位基準(zhǔn)的選擇 31 3.2.2 切削力及夾緊力的計(jì)算 32 3.2.3 定位誤差分析 33 3.2.4 夾具曲線槽設(shè)計(jì) 33 3.2.5 夾緊元件強(qiáng)度校核 33 3.2.6 操作說明 34 結(jié) 論 35 致 謝 36 參考文獻(xiàn) 37 4
