Actual departure from the production line, according to the specific requirements and functional requirements of the work environment designed a second time manipulator. First, in accordance with its intended job requirements on the material structure of the program sheet to plete feeding basic functions. Stampability functional requirements analysis to determine the degree of freedom in the table, and then determine the workbench design. According to the overall design, the design is divided into sheet feeding mechanism, the table structure of two transmission modules. Within each module, using a topdown design approach, from the original mechanism to drive mechanism, to final implementation structures, the gradual pletion of each module detailed design of specific parts, as well as important parts of the calculation and verification. Then, the main ponents of each module solidworks plete threedimensional modeling, and then each module parts for parts assembly, and finally pleted the overall assembly design. According assembly diagram to test structural design is reasonable, then continue to improve, and then continue to optimize the design to achieve the desired purpose.Keywords: Sucker feeding, feeding pulley, XY axis table translational目錄i目錄摘 要 .......................................................................IABSTRACT ...................................................................II第 1 章 緒論 .................................................................1 課題的來(lái)源 .............................................................1 課題的意義 .............................................................1 課題的研究?jī)?nèi)容 .........................................................1 行業(yè)發(fā)展趨勢(shì) ...........................................................1 國(guó)內(nèi)外研究概況 .........................................................2 論文結(jié)構(gòu)安排 ...........................................................3第 2 章總體方案的設(shè)計(jì) ........................................................5 研究方案 ...............................................................5 總體結(jié)構(gòu)設(shè)計(jì) ...........................................................5 上料裝置結(jié)構(gòu)設(shè)計(jì) .......................................................5 定位傳動(dòng)裝置結(jié)構(gòu)設(shè)計(jì) ...................................................6 主要技術(shù)指標(biāo) ...........................................................6第 3 章上料裝置 結(jié)構(gòu)設(shè)計(jì)及其校核 ..............................................7 吸盤的設(shè)計(jì)及選擇 .......................................................7 概述 ................................................................7 真空吸盤的特點(diǎn) .......................................................8 真空吸盤的分類 ......................................................8 真空吸盤的材質(zhì) ......................................................9 真空吸盤的選擇 ......................................................9 直線導(dǎo)軌的選擇 ........................................................10 滾珠絲杠導(dǎo)軌的特點(diǎn) .................................................11 同步齒形帶導(dǎo)軌的特點(diǎn) ...............................................11 直線導(dǎo)軌的選型 ......................................................11 同步帶概述 ............................................................12目錄ii 同步帶的特點(diǎn) ........................................................12 同步帶傳動(dòng)的設(shè)計(jì)準(zhǔn)則 ...............................................13 同步帶分類 ..........................................................13 上料裝置結(jié)構(gòu)元件計(jì)算與校核 ............................................13 伺服電機(jī)的計(jì)算 ......................................................13 同步帶傳動(dòng)設(shè)計(jì)計(jì)算 ..................................................13 同步輪的設(shè)計(jì) .......................................................16第四章 機(jī)床工作臺(tái)的設(shè)計(jì) 及其校核 ............................................17 工作臺(tái)的組成 ..........................................................17 絲桿傳動(dòng)裝置 ........................................................17 導(dǎo)軌副元件 ..........................................................17 夾緊裝置 ...........................................................17 驅(qū)動(dòng)元件 ...........................................................18 工作臺(tái)的組成元件的選擇 ................................................18 電機(jī)的選擇 ..........................................................18 絲桿的選擇 .........................................................19 導(dǎo)軌副的選擇 ........................................................19 夾緊元件的選擇 ......................................................20 工作臺(tái)的結(jié)構(gòu)設(shè)計(jì) ......................................................20 機(jī)床工作臺(tái)的結(jié)構(gòu)校核 ..................................................20 滾珠絲桿的校核 ..........................................
