液壓傳動機(jī)械手的設(shè)計
機(jī)械設(shè)計制造及其自動化 指導(dǎo)老師：
摘 要 本次設(shè)計的液壓傳動機(jī)械手根據(jù)規(guī)定的動作順序，綜合運用所學(xué)的基本理論、基本知識和相關(guān)的機(jī)械設(shè)計專業(yè)知識，完成對機(jī)械手的設(shè)計，并繪制必要裝配圖、液壓系統(tǒng)圖、PLC控制系統(tǒng)原理圖。機(jī)械手的機(jī)械結(jié)構(gòu)采用油缸、螺桿、導(dǎo)向筒等機(jī)械器件組成；在液壓傳動機(jī)構(gòu)中，機(jī)械手的手臂伸縮采用伸縮油缸，手腕回轉(zhuǎn)采用回轉(zhuǎn)油缸，立柱的轉(zhuǎn)動采用齒條油缸，機(jī)械手的升降采用升降油缸，立柱的橫移采用橫向移動油缸；在PLC控制回路中，采用的PLC類型為FX2N，當(dāng)按下連續(xù)啟動后，PLC按指定的程序，通過控制電磁閥的開關(guān)來控制機(jī)械手進(jìn)行相應(yīng)的動作循環(huán)，當(dāng)按下連續(xù)停止按鈕后，機(jī)械手在完成一個動作循環(huán)后停止運動。
本設(shè)計擬開發(fā)的上料機(jī)械手可在空間抓放物體，動作靈活多樣，可代替人工在高溫和危險的作業(yè)區(qū)進(jìn)行作業(yè)，可抓取重量較大的工件。

The design of the hydraulic manipulator
Machine Design & Manufacture and Automation Instructor :
Abstract The design of hydraulic drive manipulator movements under the provisions of the order ， use the basic theory, basic knowledge and related mechanical design expertise comprehensively to complete the design，and drawing the necessary assembly, hydraulic system map, PLC control system diagram . Manipulator mechanical structure using tanks, screw ,guide tubes and other mechanical device component ；In the hydraulic drive bodies ，manipulator arm stretching using telescopic tank ，rotating column of tanks used rack ，manipulator movements using tank movements ，the column takes the horizontal movement of tanks ；The PLC control circuit use the type of FX2N PLC .When pressed for commencement ，PLC in accordance with the prescribed procedures ，through the control of the solenoid valve to control the switch manipulator corresponding moves cycle ，after press the row stop button , the manipulator complete a cycle of action to stop after the hole campaign.
The design of the proposed development of the information on the manipulator can grasp up in space objects ，flexible and varied movements ，can replace the artificial heat and dangerous operation conducted operations，and can grasp the larger workpieces .
