【正文】 為了實現(xiàn)多工位加工而制造的分度工作臺和回轉(zhuǎn)工作臺等。由于消費結(jié)構(gòu)和銷售形式的變化，加之國際貿(mào)易的發(fā)展，對自動送料機的需求日益增加，因此國外自動送料機的產(chǎn)量逐年增長；其次自動送料機產(chǎn)品門類齊全，品種繁多。我國大多數(shù)企業(yè)技術(shù)水平不高，生產(chǎn)能力較低，生產(chǎn)以單機為主的中、小型自動送料機比較適宜，但要在此基礎上不斷提高制造精度、自動化程度和配套能力；（3）在自動送料機生產(chǎn)中，大量引入高新技術(shù)，研制組合式、模塊式等先進結(jié)構(gòu)，使自動送料機產(chǎn)品設計先進、使用可靠，使其性能指標、工藝水平、“三化”水平高，向機電結(jié)合、主輔機結(jié)合、成套聯(lián)線方向發(fā)展；（4）以滿足重點商品的包裝為出發(fā)點，發(fā)展自動送料機新品種。其運動路線、速度以及結(jié)構(gòu)合理性要求較高，尤其是對結(jié)構(gòu)合理性具有特殊要求。本課題主要研究數(shù)控沖床送料機的結(jié)構(gòu)設計，其主要涉及送料機的機械傳動裝置、元件的導向機構(gòu)、機構(gòu)的支撐系統(tǒng)、應用電伺服驅(qū)動、執(zhí)行元件的氣動驅(qū)動等裝置。由此可見，實現(xiàn)生產(chǎn)機械化和建立現(xiàn)代生產(chǎn)工業(yè)，乃是關系到國家長遠規(guī)劃的一件大事，也是搞好社會主義四個現(xiàn)代化的一項重要內(nèi)容。本課題主要解決大尺寸平板材料的數(shù)控送料，以替代人工送料，實現(xiàn)大尺寸平板材料沖壓送料的自動化。關鍵詞：吸盤上料，皮帶輪送料，XY 軸工作臺平動AbstractII ABSTRACTThis paper introduces a used sheet metal CNC Feeder structural design. 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 課題的來源 .............................................................1 課題的意義 .............................................................1 課題的研究內(nèi)容 .........................................................1 行業(yè)發(fā)展趨勢 ...........................................................1 國內(nèi)外研究概況 .........................................................2 論文結(jié)構(gòu)安排 ...........................................................3第 2 章總體方案的設計 ........................................................5 研究方案 ...............................................................5 總體結(jié)構(gòu)設計 ...........................................................5 上料裝置結(jié)構(gòu)設計 .......................................................5 定位傳動裝置結(jié)構(gòu)設計 ...................................................6 主要技術(shù)指標 ...........................................................6第 3 章上料裝置 結(jié)構(gòu)設計及其校核 ..............................................7 吸盤的設計及選擇 .......................................................7 概述 ................................................................7 真空吸盤的特點 .......................................................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 直線導軌的選擇 ........................................................10 滾珠絲杠導軌的特點 .................................................11 同步齒形帶導軌的特點 ...............................................11 直線導軌的選型 ......................................................11 同步帶概述 ............................................................12目錄ii 同步帶的特點 ........................................................12 同步帶傳動的設計準則 ...............................................13 同步帶分類 ..........................................................13 上料裝置結(jié)構(gòu)元件計算與校核 ............................................13 伺服電機的計算 ......................................................13 同步帶傳動設計計算 ..................................................13 同步輪的設計 .......................................................16第四章 機床工作臺的設計 及其校核 ............................................17 工作臺的組成 ..........................................................17 絲桿傳動裝置 ........................................................17 導軌副元件 ..........................................................17 夾緊裝置 ...........................................................17 驅(qū)動元件 ...........................................................18 工作臺的組成元件的選擇 ................................................18 電機的選擇 ..........................................................18 絲桿的選擇 .........................................................19 導軌副的選擇 ........................................................19 夾緊元件的選擇 ......................................................20 工作臺的結(jié)構(gòu)設計 ......................................................20 機床工作臺的結(jié)構(gòu)校核 ..................................................20 滾珠絲桿的校核 ......................................................20 伺服電機的校核 .....
