【正文】 abroad using a buildingblock most of the block structure, not only 氣動機(jī)械手設(shè)計(jì) 38 the size of a pact, but with very easy maintenance. Implementation of ponents to improve the positioning accuracy, stiffness increased, nonrotating piston rod, the use of more convenient. In order to improve the positioning accuracy of the cylinder, with brake servo system and the increasing application of the cylinder. Servo system with the cylinder, even if the gas pressure and the negative changes in the load can still receive the positioning accuracy of 177。 . In the international exhibition, a variety of specialshaped crosssection cylinder and the cylinder piston rod a lot, as a result of this type of cylinder piston rod will not turn, used in the host without additional deviceoriented to maintain a certain accuracy. In addition, a number of developmentoriented institutions with a variety of cylinder and cylinder sliding ponents, such as with a twounderoriented cylinder, double cylinder such as cylinder piston rod double. Cylinder tube has not limited to a circular shape, but square, riceshaped or other shape, in profile slot on the setoriented, sensors and switches such as the installation of slot to enable users to install more convenient to use. Multifunction, and posite. For the convenience of users, to adapt to the needs of the market has developed more than a variety of pneumatic ponents by the bination of control devices with a small pneumatic system. Such as small items for mobile ponents, is the band director, respectively, according to the twocylinder Xaxis and Zaxis bination. The movable ponents 3kg weights with Solenoid Valve, programcontrolled device, pact structure, occupy space, adjustable travel. Another example is an upper and lower feed module, there are seven different forms of functional modules, to plete the assembly line precision, the cutting operation, will be operating may be any bination of different modules. There is also a manipulator and by the appearance of small swing can change the swing angle of the cylinder assembly and the chuck, chuck 氣動機(jī)械手設(shè)計(jì) 39 parts have a number of optional chucks. And electronic technology, largescale use of sensors, intelligent pneumatic ponents. With switch has been the widespread use of domestic cylinders, switch size will be smaller, higher performance can be embedded in the cylinder block。 some with twocolor display can be shows the location of the error, making the system more reliable. Replace the flow meter sensors, pressure gauges, automatic control of pressed air can flow, pressure, can use energysaving devices and to ensure normal operation. Pneumatic servo positioning system products have been entering the market. The system uses three Wutong pneumatic servo valve, the predetermined target detection and location of the sensor data, the implementation of negative feedback control. Cylinder up to a maximum speed of 2m / s, stroke 300mm, the system positioning accuracy of 177。 . Japan39。s successful trial of a new intelligent solenoid valve, the valve with a sensor logic circuit, is pneumatic ponents and optoelectronics products of technology. It can directly accept the signal sensor when the signal to meet the specified conditions, without going through the external controller, you can plete action on its own to control purposes. It has been applied to objects on the conveyor belt, to identify the size of moving objects, so that direct the next big delivery, small pieces of triage. Higher safety and reliability. From pneumatic technology in recent years, international standards, we can see that the standard not only the interchangeability requirements and stressed the importance of security. Pipe joints, gas shells, such as the source of pressure to deal with the pressure of the pilot pressure to the 4 to 5 times the pressure of time to 5 ~ 15min, but also in the highand lowtemperature test. If you implement these international standards, domestic cylinder tube, end caps, gas processing, such as castings and fittings could not meet the standards. In addition to the pilot pressure, the structure also made certain provisions, such as the gas source to deal with the 氣動機(jī)械手設(shè)計(jì) 40 provisions of the transparent outer shell to increase the metal shield. 第五章 結(jié)束語 氣動技術(shù)經(jīng)歷了一個漫長的發(fā)展過程，隨著氣動伺服技術(shù)走出實(shí)驗(yàn)室，氣動技術(shù)及氣動機(jī)械手迎來了嶄新的春天。目前在世界上形成了以日本、美國和歐盟氣動技術(shù)、氣動機(jī)械手三足鼎立的局面。我國對氣動技術(shù)和氣動機(jī) 械手的研究與應(yīng)用都比較晚，但隨著投入力度和研發(fā)力度的加大，我國自主研制的許多氣動機(jī)械手已經(jīng)在汽車等行業(yè)為國家的發(fā)展進(jìn)步發(fā)揮著重要作用。隨著微電子技術(shù)的迅速發(fā)展和機(jī)械加工工藝水平的提高及現(xiàn)代控制理論的應(yīng)用，為研究高性能的氣動機(jī)械手奠定了堅(jiān)實(shí)的物質(zhì)技術(shù)基礎(chǔ)。由于氣動機(jī)械手有結(jié)構(gòu)簡單、易實(shí)現(xiàn)無級調(diào)速、易實(shí)現(xiàn)過載保護(hù)、易實(shí)現(xiàn)復(fù)雜的動作等諸多獨(dú)特的優(yōu)點(diǎn)，可以預(yù)見，在不久的將來，氣動機(jī)械手將越來越廣泛地進(jìn)人工業(yè)、軍事、航空、醫(yī)療、生活等領(lǐng)域。 通過這次設(shè)計(jì)讓我認(rèn)識了很多，也學(xué)到了很多，對三維實(shí)體的制作不僅讓我更加熟悉了 PRO/E 的操作，更讓我深刻了解了整體與局部的關(guān)系，可以說是牽一發(fā)而動全身，一個小小的尺寸或是設(shè)置的錯誤都可能讓你再次做你做過好多遍的工作，就是因?yàn)榇笠狻３绦虻木帉懯刮以僖淮文闷鹆司眠`的課本，課本依舊，只是有些舊了，但從中找到的不僅有過往的甜美氣息，還有那我們以前不以為然的公式、算數(shù)、符號 ? 慢慢的在記憶中沉浸，又浮起，氣動機(jī)械手設(shè)計(jì) 41 吃飯的時候就會想起古人的兩句話： 當(dāng)時只道是尋常！ 溫故而知新！ 錯過的已然錯過！努力向前才 是最重要的。 第六章 參考文獻(xiàn) (1) 丁繼斌、封士彩 ,《機(jī)械系統(tǒng)設(shè)計(jì)及其控制技術(shù)》 ,化學(xué)工業(yè)出版社 (2) 郁建平 ,《機(jī)電綜合實(shí)踐》 ,科學(xué)技術(shù)出版社 (3) 鄭玉華 ,《典型機(jī)械 (電 )產(chǎn)品構(gòu)造》 ,科學(xué)出版社 (4) 吳愛萍 , 《 PLC控制的設(shè)計(jì)技巧 》 , 2021(2):6162.
