As a result of internal heat from the workpiece, so have a wide range of resistance welding machine to use. Resistance welding technology in China has experienced the exchange frequency, DC pulse, threephase lowfrequency, secondary rectification, microprocessor control and quality control of the process technology level. At present, the use of microputercontrolled secondary rectification point / sewing machine, with constant current output of the quality control of the application of resistance welding machine has been more widespread, resistance welding quality control theory and technology, a variety of general and resistance spot welding machine dedicated / professional resistance seam welding machine slit welder, plete sets of equipment for research and applications are more mon and mature, close to international advanced level. The main requirement of the task to design a spot welder for industrial use. Such a spot welding machine used in the main workshop, conducted on the spot welding parts, welding parts to plete fixed. Such equipment can pletely replace the existing manual operation, greatly improving the productivity of machining.KEY WORDS: Spot Welder，Resistance Welding，Welding，Structural Design本科機(jī)械畢業(yè)設(shè)計(jì)論文 CAD 圖紙 401339828 目 錄摘要 …………………………………………………………………………………………ⅠABSTRACT ……………………………………………………………………………………Ⅱ1 緒論 ....................................................................1 點(diǎn)焊機(jī)概述 .............................................................1 國(guó)外電焊機(jī)科技水平的現(xiàn)狀和發(fā)展 .........................................1 國(guó)內(nèi)點(diǎn)焊機(jī)行業(yè)的發(fā)展動(dòng)向 ..............................................1 課題的目的與意義 ......................................................22 工業(yè)點(diǎn)焊機(jī)的分類與組成 ..................................................4 點(diǎn)焊機(jī)的分類 ..........................................................4 點(diǎn)焊機(jī)的基本組成 .......................................................43 點(diǎn)焊工作原理及傳動(dòng)方案的確定 ............................................7 點(diǎn)焊機(jī)工作原理簡(jiǎn)述 ....................................................7 點(diǎn)焊機(jī)工作流程簡(jiǎn)述 ................................................7 點(diǎn)焊的工作原理及影響因素 ..........................................8 傳動(dòng)系統(tǒng)的設(shè)計(jì)要求 ....................................................11 傳動(dòng)方式的 確定 .......................................................124 點(diǎn)焊機(jī)主要零部件選型 ...................................................14 電動(dòng)機(jī)的選擇 ..........................................................14 步進(jìn)電動(dòng)機(jī)簡(jiǎn)述 ...................................................14 步進(jìn)電機(jī)的應(yīng)用 ...................................................14 步進(jìn)電動(dòng)機(jī)的選擇 .................................................15 氣缸的選擇 ............................................................16 同步帶輪的選擇 ........................................................18 同步帶輪的表示方法 ...............................................18 同步帶輪規(guī)格的 選擇 ...............................................19 同步帶的安裝方法 ...............................................19 同步帶運(yùn)轉(zhuǎn)時(shí)注意事項(xiàng) .............................................19 主軸的設(shè)計(jì) ............................................................20 選擇主軸的材料 ...................................................20 初步確定主軸的直徑 ...............................................20 主軸的結(jié)構(gòu)設(shè)計(jì) ...................................................20 工件定位裝置的確定 ....................................................21本科機(jī)械畢業(yè)設(shè)計(jì)論文 CAD 圖紙 401339828 5 總結(jié) ..................................................................23致 謝 ....................................................................24參 考 文 獻(xiàn) ..............................................................25本科機(jī)械畢業(yè)設(shè)計(jì)論文 CAD 圖紙 401339828 1 緒論 點(diǎn)焊機(jī)概述點(diǎn)焊機(jī)又稱電阻焊機(jī)，是利用被焊工件的自身的電阻，在局部通過(guò)大電流產(chǎn)生高溫而使工件熔接起來(lái)的焊接設(shè)備?！ ↑c(diǎn)焊機(jī)根據(jù)焊接工件的材料及厚度不同又分為:大功率點(diǎn)焊機(jī)、精密點(diǎn)焊機(jī)、微電子點(diǎn)焊機(jī)。 國(guó)外電焊機(jī)科技水平的現(xiàn)狀和發(fā)展(1)逆變焊機(jī) 某些著名的電焊機(jī)生產(chǎn)廠對(duì)逆變焊機(jī)的不斷改進(jìn)，使它的可靠性已接近一般電焊機(jī)的故障率，即 1%左右。 (2) 非傳統(tǒng)（非電弧、電阻）焊技術(shù)的應(yīng)用和設(shè)備發(fā)展迅速，現(xiàn)已有：摩擦縫焊(Friction
