- 搬運(yùn)機(jī)械手的設(shè)計(jì) 本文簡要地介紹了工業(yè)機(jī)器人的概念，機(jī)械手的組成和分類，機(jī)械手的自由度和座標(biāo)型式，氣動技術(shù)的特點(diǎn)，PLC控制的特點(diǎn)及國內(nèi)外的發(fā)展?fàn)顩r。
本文對機(jī)械手進(jìn)行了總體方案設(shè)計(jì)，確定了機(jī)械手的座標(biāo)型式和自由度，確定了機(jī)械手的技術(shù)參數(shù)。同時(shí)，分別設(shè)計(jì)了機(jī)械手的夾持式手部結(jié)構(gòu)以及吸附式手部結(jié)構(gòu);設(shè)計(jì)了機(jī)械手的手腕結(jié)構(gòu)，計(jì)算出了手腕轉(zhuǎn)動時(shí)所需的驅(qū)動力矩和回轉(zhuǎn)氣缸的驅(qū)動力矩;設(shè)計(jì)了機(jī)械手的手臂結(jié)構(gòu)，設(shè)計(jì)了手臂伸縮、升降用液壓緩沖器和手臂回轉(zhuǎn)用液壓緩沖器。
設(shè)計(jì)出了機(jī)械手的氣動系統(tǒng)，繪制了機(jī)械手氣壓系統(tǒng)工作原理圖。利用可編 程序控制器對機(jī)械手進(jìn)行控制，選取了合適的PLC型號，根據(jù)機(jī)械手的工作流程制定了可編程序控制器的控制方案，畫出了機(jī)械手的工作時(shí)序圖和梯形圖，并編制了可編程序控制器的控制程序。

Design on the Currency Pneumatic Loading
and Unloading Manipulator
ABSTRACT
At first,the paper introduces the conception of the industrial robot and the elertary information of the development briefly. What's more,the paper accounts for background and the primary mission of thetopic.
The paper introduces the function,composing and classification of the manipulator,tells out the free-degree and the form of coordinate.At the same time,the paper gives out the primary specification parameter of this manipulator.
This paper designs the structure of the hand and the equipment of the drive of the manipulator,and analyzes the error of the orientation of the fingers.
The paper designs the structure of the wrist,computes the needed
moment of the drive when the wrist wheels and the moment of the drive of the pump.
The paper designs the structure of the arm,and designs the hydraulic pressure buffer when the manipulator's arm flexes,ascend,descend and wheels .
The paper designs the system of air pressured rive and draws the work principle chair.
The manipulator uses PLC to control.The paper institutes two controls chemes of PLC acordine to the work flow of the manipulator.The paper draws out the work time sequence chart and the trapezia chart.What’s more,the paper work out the control program of the PLC.
KEY WORDS industrial robot, manipulator, pump, air pressure drive, PLC
