摘 要
機(jī)械手是工業(yè)機(jī)器人的重要組成部分,在很多情況下它就可以稱為工業(yè)機(jī)器人。工業(yè)機(jī)器人是集機(jī)械、電子、控制、計(jì)算機(jī)、傳感器、人工智能等多學(xué)科先進(jìn)技術(shù)于一體的現(xiàn)代制造業(yè)重要的自動(dòng)化裝備。機(jī)械手是模仿人的手部動(dòng)作,按給定程序、軌跡和要求實(shí)現(xiàn)自動(dòng)抓取、搬運(yùn)和操作的自動(dòng)裝置。它特別是在高溫、高壓、多粉塵、易燃、易爆、放射性等惡劣環(huán)境中,以及笨重、單調(diào)、頻繁的操作中代替人作業(yè),因此獲得日益廣泛的應(yīng)用。機(jī)械手一般由執(zhí)行機(jī)構(gòu)、驅(qū)動(dòng)系統(tǒng)、控制系統(tǒng)及檢測裝置三大部分組成,智能機(jī)械手還具有感覺系統(tǒng)和智能系統(tǒng)。本篇是根據(jù)給定的主要技術(shù)指標(biāo)及要求,分手部,手臂伸縮,手臂回轉(zhuǎn),驅(qū)動(dòng)系統(tǒng),電氣系統(tǒng)介紹了12KG下料機(jī)械手設(shè)計(jì)過程。

ABSTRACT
The manipulator is the industry robot important constituent, It may be called the industry robot in very many situations. The industry robot is the collection machinery, electronic, thecontrol, the computer, the sensor, the artificial intelligence and soon the multi-disciplinary advanced technology to a body modernmanufacturing industry important automation equipment. The manipulator imitates person's hand movement, according to assignsthe procedure, the path and the request realization automaticallycaptures, the transporting and the operation automatic device. It specially is in the high temperature, the high pressure, the multi-dust, flammable, explosive, radioactive and so on in the adversecircumstance, as well as is unwieldy, monotonously, in the frequentoperation replaces the person work, therefore obtains day by day thewidespread application. The manipulator generally by the implementing agency, the actuationsystem, the control system and the detector set three major part iscomposed, the intelligent manipulator also has the feeling system andthe intelligent system. This is according to the main technical specification and the requestwhich assigns, divides the hand, the arm expands and contracts, thearm rotation, the actuation system, the electrical system introducedthe 12KG yummy treats manipulator designs the process.
Keywords: Manipulator Implementing agency Actuation system
