【正文】 保持正確的位置，保證達(dá)到該工序所規(guī)定的技術(shù)要求。 鏜床夾具的種類 可根據(jù)夾具在不同生產(chǎn)類型中的通用特性，機(jī)床夾具可分為通用夾具、專用夾具、可調(diào)夾具、組合夾具和自動線夾具等五大類。定位元件采用插拔銷裝置使工件在機(jī)床上獲得相應(yīng)的位置，以便加工；夾緊機(jī)構(gòu)用連桿夾緊裝置，加工工件的時候，可防止工件在切削力的作用下發(fā)生位置移動；動力源傳動機(jī)構(gòu)采用液壓動力，彌補(bǔ)手動加緊的不可自鎖性。并對切削力和夾緊力進(jìn)行計算，最后綜合設(shè)計出夾具體的整體尺寸和結(jié)構(gòu)。s living provides durable consumer goods industry， National economic sectors production technology progress and economic benefit of ruling。 So machinery industry technical level and scale to measure a country39。s fixture on the quality of the machining parts, productivity, and product cost had direct influence. Therefore, mechanical manufacturing machine tools, machine tool can depart from fixture。s fixture general characteristics can be divided into general fixture, special jig, adjustable clamp, modular fixture and automatic line jig etc. Five classes. Design of main design fixtures 12m fixture position ponents, clamping institutions, orientation device and power transmission mechanism, the bination of their eventual system. Positioning ponent is inserted pin in machine device makes the workpiece to obtain corresponding position, so that processing。 Power transmission mechanism adopts hydraulic power, make up not selflocking manual tightening gender. The focal point of design is the positioning and clamping institutions, conception is its structure, determine its size. And the cutting force and clamping force calculation, and finally prehensive design a clip concrete whole size and structure. Keywords: fixtures, positioning ponents, clamping institutions, cutting force and clamping force 洛陽理工學(xué)院畢業(yè)設(shè)計（論文） IV 目 錄 前 言 ....................................................................................................... 1 第 1 章 概述 ............................................................................................ 2 夾具的功用和分類 .................................................................... 2 夾具的功用 ...................................................................... 2 夾具的分類 ...................................................................... 2 夾具的組成 ...................................................................... 2 夾具體 ........................................................................................ 3 夾具體概念 ...................................................................... 3 夾具體設(shè)計的基本 要求 ................................................. 3 第 2 章 零件工藝過程分析 .................................................................... 4 零件的加工工藝路線的制定與分析 ....................................... 4 設(shè)計要求 .......................................................................... 4 工藝路線分析步驟 ......................................................... 4 待加工工件圖 ............................................................................ 5 立式底座體工件圖 .......................................................... 5 第 3 章 工件的定位分析和結(jié)構(gòu)設(shè)計 ................................................... 6 工件定位的基本原理 ............................................................... 6 自由度的概念 ................................................................. 6 六點定位原理 ................................................................. 6 定位中的幾種情況 .......................................................... 7 常用定位元件及選用 ............................................................... 7 定位中的幾種情況 .......................................................... 7 常用定位元件所能限制的自由度 ................................. 8 定位方案的確定：一面兩孔定位 ........................................... 8 第 4 章 夾緊裝置的組成 ...................................................................... 10 夾緊裝置 .................................................................................. 10 夾緊要則 ........................................................................ 10 夾緊機(jī)構(gòu)的分類 ........................................................... 10 洛陽理工學(xué)院畢業(yè)設(shè)計（論文） V 夾緊裝置的組成 ............................................................11 夾緊機(jī)構(gòu)的基本要求 ....................................................11 夾緊方案的確定 ...................................................................... 12 第 5 章 夾緊力的計算 ..................................
