【摘要】：水潤滑軸承作為機(jī)械傳動系統(tǒng)中的關(guān)鍵零部件，利用新型工程復(fù)合材替代貴重金屬，用水代替礦物油作為機(jī)械傳動系統(tǒng)的潤滑介質(zhì)，不僅節(jié)約大量的油料,還可以避免以油為潤滑介質(zhì)對環(huán)境造成的污染，因而具有資源節(jié)約、環(huán)境友好、結(jié)構(gòu)簡單、高性能等優(yōu)點(diǎn)，近年來得到了廣泛應(yīng)用。因此，如何實(shí)現(xiàn)水潤滑軸承制造加工的自動化、高效化這一課題吸引了越來越多企業(yè)和專家學(xué)者的關(guān)注。但是長期以來，水潤滑軸承在硫化機(jī)上完成硫化成型之后，大多依靠工人在普通車床上完成對水潤滑軸承毛坯的平端面、車外圓和倒角的操作，導(dǎo)致水潤滑軸承的生產(chǎn)效率低，工人勞動強(qiáng)度大、工作環(huán)境惡劣。因此，設(shè)計(jì)一套能夠?qū)崿F(xiàn)水潤滑軸承高效自動加工的設(shè)備具有重要的工程實(shí)際意義。本文提出一套水潤滑軸承柔性平臺，該平臺由一臺雙臂機(jī)器人、數(shù)控車床、上下料系統(tǒng)和機(jī)械手組成，它能夠?qū)崿F(xiàn)水潤滑軸承的柔性自動加工，其中上下料系統(tǒng)和機(jī)械手需要設(shè)計(jì)。本課題的重點(diǎn)是設(shè)計(jì)上下料系統(tǒng)和機(jī)械手，實(shí)現(xiàn)上下料系統(tǒng)的自動控制。本文研究的主要內(nèi)容可以概括如下： ①分析國內(nèi)外常見的圓柱體工件物料輸送設(shè)備，根據(jù)水潤滑軸承的尺寸、重量和外形，設(shè)計(jì)一套能滿足不同規(guī)格的水潤滑軸承坯料輸送和成品回收的上下料系統(tǒng)。 ②以PLC為控制硬件核心，選擇適合的觸摸屏、變頻器、光電傳感器和繼電器等控制硬件，組成PLC控制系統(tǒng)，根據(jù)需要實(shí)現(xiàn)的功能繪制控制流程圖，編寫PLC梯形圖程序，實(shí)現(xiàn)上下料系統(tǒng)的自動控制。 ③比較常用機(jī)械手的優(yōu)缺點(diǎn)和原理，根據(jù)所需要抓取的水潤滑軸承的外形、重量和機(jī)器人末端機(jī)械接口尺寸，，設(shè)計(jì)兩只能夠?qū)崿F(xiàn)不同規(guī)格的水潤滑軸承抓取的氣動機(jī)械手。 ④利用SolidWorks三維CAD軟件建立該氣動機(jī)械手的虛擬樣機(jī)模型，并進(jìn)行虛擬裝配和干涉分析。利用ANSYS Workbench有限元軟件對機(jī)械手進(jìn)行有限元分析，得到機(jī)械手各部件的應(yīng)力云圖，檢驗(yàn)機(jī)械手各部件的強(qiáng)度是否符合要求。 ⑤利用ADAMS對氣動機(jī)械手進(jìn)行動力學(xué)分析，檢驗(yàn)機(jī)械手的夾緊力與設(shè)計(jì)是否相符。
[Abstract]:Water lubricated bearing is the key part in mechanical transmission system. It not only saves a large amount of oil but also uses new engineering composite to replace precious metal and mineral oil to replace mineral oil as lubricating medium of mechanical transmission system. It can also avoid environmental pollution caused by oil as lubricating medium, so it has the advantages of saving resources, friendly environment, simple structure and high performance, and has been widely used in recent years. How to automate the manufacture and processing of water lubricated bearings has attracted the attention of more and more enterprises and experts. But for a long time, water lubricated bearings have been vulcanized in vulcanization press. Most of them depend on the workers to finish the operation of the water lubricated bearing blank on the ordinary lathe, which leads to the low production efficiency of the water lubricated bearing, the heavy labor intensity of the workers, and the bad working environment. It is of great practical significance to design a set of equipment that can realize high efficiency automatic machining of water lubricated bearings. This paper presents a flexible platform for water lubricated bearings, which consists of a double arm robot and a numerical control lathe. The loading and unloading system and manipulator can realize the flexible automatic machining of water lubricated bearing in which the loading and unloading system and manipulator need to be designed. The emphasis of this subject is to design the loading and unloading system and manipulator. The main contents of this paper can be summarized as follows: 1. Analyze the common material conveying equipment of cylindrical workpiece at home and abroad, according to the size, weight and shape of water lubricated bearing. Design a feeding system which can meet different specifications of water lubricated bearing billet transportation and product recovery. (2) take PLC as the control hardware core, select suitable control hardware such as touch screen, frequency converter, photoelectric sensor and relay, compose the PLC control system, draw the control flow chart according to the function that needs to be realized. PLC trapezoidal diagram program is written to realize the automatic control of the upper and lower feeding system. 3Compared the advantages and disadvantages and the principle of common manipulator, according to the need to grasp the water lubricated bearing shape, weight and robot end mechanical interface size. Two pneumatic manipulators are designed which can grasp water lubricated bearings of different specifications. (4) the virtual prototype model of the pneumatic manipulator is established by using SolidWorks 3D CAD software. The virtual assembly and interference analysis are carried out. The finite element analysis of the manipulator is carried out by using ANSYS Workbench finite element software, and the stress cloud diagram of each component of the manipulator is obtained. Check whether the strength of the components of the manipulator meets the requirements. 5 using ADAMS to analyze the dynamics of the pneumatic manipulator to verify whether the clamping force of the manipulator is in accordance with the design.
