摘 要
本課題運(yùn)用制圖軟件對(duì)機(jī)械手采摘油茶進(jìn)行機(jī)構(gòu)設(shè)計(jì)。包括：旋轉(zhuǎn)機(jī)構(gòu)，蝸輪蝸桿減速裝置，直齒減速裝置；升降機(jī)構(gòu)，氣壓缸升降裝置；擺臂機(jī)構(gòu)，氣壓裝置和四桿裝置；手抓機(jī)構(gòu)，滑動(dòng)螺旋傳動(dòng)裝置，手抓抓緊放開(kāi)裝置，手抓自轉(zhuǎn)裝置；PLC程控系統(tǒng)，繼電器-接觸器控制系統(tǒng)，主電路，PLC外部接線，梯形圖，指令語(yǔ)句表。用AutoCAD繪制機(jī)構(gòu)的二維圖形，用Pro/E繪制機(jī)構(gòu)的三維造型。熟練掌握AutoCAD和Pro/E繪圖，對(duì)機(jī)械原理、機(jī)械設(shè)計(jì)及機(jī)電一體化有較深入的理解和認(rèn)識(shí)。

關(guān)鍵詞：油茶采摘、機(jī)械手、PLC程序控制系統(tǒng)

Abstract
  This subject uses the software of making maps to pluck the tea-oil camellia and design the organization to the manipulator. Including the rotate organization, the worm gear worm decelerating device,the spur gear decelerating device;the hoist or lower organization, the barometric pressure cylinder hoists or lower device; the wave arm organization, atmospheric pressure device and four device ,the skids screw gearing,the hold organization , the slip spiral transmission device, the holding and unlock device, hold the rotation device ; PLC programme-controlled system, the relay - contact device control system.Main circuit, PLC exterior wiring, trapezoidal chart, instruction sentence table.Draw the two-dimentional figures of the organization with AutoCAD, draw the three-dimensional model of the organization with Pro/E. Grasp AutoCAD and Pro/E drawing skillfully, integrate deeper understanding and know to mechanism, machine design and integration of machinery.

Key words:The tea-oil tree picks, the manipulator, the PLC procedure control system
