湘潭三峰數(shù)控機(jī)床有限公司 參觀實(shí)習(xí)報(bào)告 指導(dǎo)老師 鄧朝暉 前言：隨著科學(xué)技術(shù)飛速發(fā)展，磨削加工技術(shù)成為先進(jìn)制造技術(shù)的重要領(lǐng)域，磨削具有高幾何精度，低速進(jìn)給運(yùn)動(dòng)穩(wěn)定性，減少震動(dòng)，減少熱變形；而磨削加工的要求不斷增高，這讓我們學(xué)習(xí)磨削加工技術(shù)帶來(lái)了挑戰(zhàn)和機(jī)遇。在以往學(xué)習(xí)生活對(duì)磨床接觸甚少，便需外面公司學(xué)習(xí)了解，因此，鄧?yán)蠋煱才帕舜舜稳ハ嫣度鍞?shù)控機(jī)床有限公司參觀實(shí)習(xí)。 公司簡(jiǎn)介：公司以國(guó)家高效磨削工程技術(shù)研究中心為依托，并與桂林桂北磨床和湖南大學(xué)、湘潭大學(xué)、湖南科技大學(xué)等多家高校形成戰(zhàn)略聯(lián)盟的關(guān)系，具備雄厚的產(chǎn)品研發(fā)能力和先進(jìn)的制造工藝，是國(guó)內(nèi)數(shù)控精密磨床制造企業(yè)中具有自主知識(shí)產(chǎn)權(quán)的重點(diǎn)企業(yè)之一。所研發(fā)生產(chǎn)的多功能全數(shù)控磨床、磨削加工中心、對(duì)稱(chēng)式坐標(biāo)磨床屬?lài)?guó)內(nèi)首創(chuàng)，獲得了多項(xiàng)國(guó)家發(fā)明專(zhuān)利，其中高檔多功能全數(shù)控磨床和磨削加工中心的工藝智能應(yīng)用系統(tǒng)軟件填補(bǔ)了國(guó)內(nèi)空白。 公司主要產(chǎn)品有： SFMK6020多功能數(shù)控磨床、 SFMK6315磨削加工中心、 SFM6312內(nèi)存式平面磨床、SFMK4016內(nèi)存式平面磨床、 SFMM7132精密數(shù)控平面磨床、 SFM7130平面磨床、 普通臥軸平面磨床系列等。 公司長(zhǎng)期以來(lái)以市場(chǎng)為導(dǎo)向、以技術(shù)創(chuàng)新為本，以服務(wù)用戶(hù)為宗旨，秉承以人為本，科技領(lǐng)先，誠(chéng)信經(jīng)營(yíng)，創(chuàng)知名品牌的方針，在市場(chǎng)經(jīng)濟(jì)的大湖中逐步實(shí)現(xiàn)穩(wěn)定、持續(xù)、快速的發(fā)展，用心鑄造“三相”品牌，不斷開(kāi)拓創(chuàng)新，為市場(chǎng)研制更多高精、高效、智能化的產(chǎn)品。 參觀過(guò)程：在學(xué)長(zhǎng)的帶領(lǐng)下，我們首先參觀了托板內(nèi)存式M7140/N平面磨床和臥軸炬臺(tái)平面磨床。橫向進(jìn)給和縱向進(jìn)給均采用液壓控制，垂直進(jìn)給采用滾珠絲杠控制，了解滾珠絲杠的工作原理，滾珠絲杠副又名滾珠絲桿副、滾珠螺桿副。是由絲杠及螺母二個(gè)配套組成的。是目前傳動(dòng)機(jī)械中精度最高也是最常用的傳動(dòng)裝置。滾珠絲桿副是在絲杠與螺母間以鋼球?yàn)闈L動(dòng)體的螺旋傳動(dòng)元件。它可將旋轉(zhuǎn)運(yùn)動(dòng)轉(zhuǎn)變?yōu)橹本€運(yùn)動(dòng)，或者將直線運(yùn)動(dòng)轉(zhuǎn)變?yōu)樾D(zhuǎn)運(yùn)動(dòng)。因此滾珠絲杠副既是傳動(dòng)原件，也是直線運(yùn)動(dòng)與旋轉(zhuǎn)運(yùn)動(dòng)相互轉(zhuǎn)化元件。滾珠絲杠副在絲母部分的構(gòu)造上有獨(dú)到之處。按滾珠的循環(huán)方式可分為彎管式絲杠副與絲母之間設(shè)有滾珠轉(zhuǎn)動(dòng)溝道,滾珠對(duì)溝道產(chǎn)生軸向負(fù)載,滾珠在絲杠軸周?chē)鰸L動(dòng)運(yùn)動(dòng)之后,進(jìn)入鑲在絲母內(nèi)部的彎管口內(nèi),并沿彎管再次向負(fù)載區(qū)循環(huán),從而進(jìn)行無(wú)限滾動(dòng)運(yùn)動(dòng)。這種產(chǎn)品是滾珠絲杠副中品種最豐富的普及型產(chǎn)品，可廣泛用于各種用途。另外還有回球器式和端環(huán)境式 砂輪架由殼體，主軸及其軸承，傳動(dòng)裝置及滑鞍等組成；砂輪架中的砂輪主軸及其支承部分的結(jié)構(gòu)將直接影響工件的加工精度和表面粗糙度，這是砂輪架部件的關(guān)鍵部分，它應(yīng)保證砂輪架主軸具有較高的回轉(zhuǎn)精度、剛度、抗震性和耐磨性。 砂輪架殼體用螺釘緊固在滑鞍上，他可繞滑鞍上的定心圓柱調(diào)整位置。磨削時(shí)，滑鞍帶著砂輪架沿墊板上的導(dǎo)軌作橫向進(jìn)給運(yùn)動(dòng)。 參觀了蝸輪蝸桿的安裝過(guò)程，由渦輪、蝸桿軸承及及伺服電機(jī)組成以控制垂直方向進(jìn)給。 砂輪修整器的構(gòu)造安裝及修整演示過(guò)程; 定期修整可使砂輪保持良好的磨削性能和正確的幾何形狀，避免出現(xiàn)砂輪的鈍化、堵塞和外形失真，常使用的修整工具是金剛石筆。操作時(shí)，修整工具位置過(guò)高、修整方向不當(dāng)（如逆砂輪旋轉(zhuǎn)方向，傾斜角過(guò)大過(guò)?。┗蛐拚窟^(guò)大，都會(huì)使砂輪產(chǎn)生強(qiáng)烈振動(dòng)，或引起金剛石筆啃刀，嚴(yán)重的還會(huì)導(dǎo)致砂輪破裂。正確的操作方法是：金剛石筆處于砂輪中心水平線下1～2mm處，順砂輪旋轉(zhuǎn)方向，與水平面的傾斜角為5°～10°左右。修整時(shí)要用力均勻，速度平穩(wěn)，一次修整量不要過(guò)大。操作者應(yīng)站在砂輪的側(cè)方安全位置，不可站在砂輪正面操作?！⌒拚蟮纳拜啽仨氈匦陆?jīng)回轉(zhuǎn)試驗(yàn)后，方可使用。 操作平臺(tái)以V行槽和平面槽相結(jié)合以保證定位精度；將加工使用過(guò)的平臺(tái)進(jìn)行檢測(cè)平整度通過(guò)調(diào)整兩端高度調(diào)節(jié)。最后，以其中一臺(tái)磨床做了操作演示，我們有一個(gè)整體工作原理效果。 參觀總結(jié)：通過(guò)此次在湘潭三峰數(shù)控機(jī)床有限公司參觀實(shí)習(xí)，收貨頗豐，在以前磨床是一個(gè)很模糊的概念轉(zhuǎn)變?yōu)樵砬逦鸂顟B(tài)，讓人豁然開(kāi)朗起來(lái)！從大概念上來(lái)說(shuō)磨床的加工運(yùn)動(dòng)并不復(fù)雜，就是一個(gè)分三個(gè)方向的進(jìn)給。但是每部分都有許多輔助零件，回想起來(lái)那就有點(diǎn)腦殼疼了！我想就讓這些問(wèn)題在設(shè)計(jì)過(guò)程中慢慢被我弄清楚，并且最好能將其改善。一步步在熟悉磨床這個(gè)工種；我想在通過(guò)進(jìn)一步的查看資料，剖析磨床原理和先進(jìn)加工技術(shù)。 姓名 周 武 學(xué)號(hào) 1103010305 班級(jí) 3 班 學(xué)院 機(jī)電工程學(xué)院 畢業(yè)設(shè)計(jì)開(kāi)題報(bào)告 題目 立柱移動(dòng)式MK7125型精密數(shù)控平面磨床砂輪架及其垂直進(jìn)給機(jī)構(gòu)和砂輪修整器設(shè)計(jì) 姓名 周 武 學(xué)院 機(jī)電工程學(xué)院 專(zhuān)業(yè) 機(jī)械設(shè)計(jì)制造及其自動(dòng)化 學(xué)號(hào) 1103010305 指導(dǎo)老師 鄧朝暉 教授 二〇一五年 三月 二十一日 湖南科技大學(xué) 2015 屆畢業(yè)設(shè)計(jì)（論文）開(kāi)題報(bào)告 題 目 立柱移動(dòng)式MK7125型精密數(shù)控平面磨床砂輪架 及其垂直進(jìn)給機(jī)構(gòu)和砂輪修整器設(shè)計(jì) 作者姓名 周武 學(xué)號(hào) 1103010305 所學(xué)專(zhuān)業(yè) 機(jī)械設(shè)計(jì)制造 及其自動(dòng)化 1、 研究的意義，同類(lèi)研究工作的國(guó)內(nèi)外現(xiàn)狀 背景和研究意義 磨床是磨料磨具為工具進(jìn)行加工切削的機(jī)床，廣泛應(yīng)用于零件的精加工，尤其是淬硬鋼件、高硬度特殊材料及其非金屬材料的精加工。在模具制造領(lǐng)域，磨床也是不可缺少的工藝裝備。近年來(lái)，隨著科學(xué)技術(shù)的及工業(yè)的發(fā)展，各種高硬度材料日益增多，汽車(chē)和高端芯片產(chǎn)業(yè)也迅猛發(fā)展，對(duì)機(jī)器和儀器零件的精度和表面粗糙度要求越來(lái)越嚴(yán)，磨削加工就顯得尤為重要。此外，高端磨削和強(qiáng)力磨削工業(yè)的發(fā)展使磨削效率進(jìn)一步提高，因此，磨床的使用范圍日益擴(kuò)大。目前，他在金屬切削機(jī)床中所占的比重已經(jīng)達(dá)到13%~27%。1997年歐洲機(jī)床展覽會(huì)的調(diào)查數(shù)據(jù)表明，25%的企業(yè)認(rèn)為磨削技術(shù)是他們應(yīng)用的最主要加工技術(shù)。基于磨床在現(xiàn)代制造業(yè)中的重要作用，本次畢業(yè)設(shè)計(jì)的課題為設(shè)計(jì)一臺(tái)用于機(jī)械及工具模具制造業(yè)的精密數(shù)控平面磨床，用砂輪周邊磨削平面既可以磨削臺(tái)階平面，也能加工各種難加工材料。這個(gè)不光可以使我們能夠綜合應(yīng)用四年以來(lái)所學(xué)的專(zhuān)業(yè)知識(shí)，為今后的深造和就業(yè)打好基礎(chǔ)，還可以使我們對(duì)國(guó)內(nèi)外機(jī)械制造業(yè)、磨床行業(yè)有進(jìn)一步的認(rèn)識(shí)和了解。 國(guó)內(nèi)外研究狀況 平面磨床相對(duì)于車(chē)床、銑床等采用數(shù)控系統(tǒng)較晚，應(yīng)為他對(duì)數(shù)控系統(tǒng)的特殊要求。近十幾年來(lái)，借助CNC技術(shù)，磨床上砂輪的連續(xù)修整，自動(dòng)補(bǔ)償，自動(dòng)交換砂輪，多工作臺(tái)，自動(dòng)傳送和裝夾工件等操作功能得以實(shí)現(xiàn)，數(shù)控技術(shù)在平面磨床上逐漸普及。在近年漢諾威、東京、芝加哥、及國(guó)內(nèi)大型機(jī)床展覽會(huì)上，CNC磨床在整個(gè)磨床展品中已占大多數(shù)，如德國(guó)BLOHM公司，ELB公司等著名磨床制造廠已經(jīng)不再生產(chǎn)普通磨床，日本的岡本、日興等公司也成批生產(chǎn)全功能CNC平磨，在開(kāi)發(fā)高檔數(shù)控平磨的同時(shí)，積極發(fā)展中、低檔數(shù)控平磨。 目前，磨床設(shè)備的綜合性能，在我國(guó)的整體制造水平與國(guó)外先進(jìn)水平相比，仍然有很大的差距。研究和開(kāi)發(fā)具有能耗低，效率高，適應(yīng)性強(qiáng)的精密磨床是符合我國(guó)國(guó)情的。 2、 研究目標(biāo)、內(nèi)容和擬解決的關(guān)鍵問(wèn)題（根據(jù)任務(wù)要求進(jìn)一步具體化） 本次設(shè)計(jì)的目標(biāo)為： 1、 磨床總體布局設(shè)計(jì)； 2、 砂輪架設(shè)計(jì)計(jì)算，繪制砂輪架機(jī)械結(jié)構(gòu)裝配圖； 3、砂輪架垂直進(jìn)給機(jī)構(gòu)的設(shè)計(jì)，伺服電機(jī)和滾珠絲杠副設(shè)計(jì)計(jì)算，繪制垂直進(jìn)給機(jī)構(gòu)結(jié)構(gòu)裝配圖，繪制相關(guān)零件圖； 3、砂輪修整器設(shè)計(jì)，繪制砂輪修整器機(jī)械結(jié)構(gòu)裝配圖； 4、磨床數(shù)控系統(tǒng)設(shè)計(jì)和選用； 5、翻譯制定的英文專(zhuān)業(yè)文獻(xiàn)； 6、撰寫(xiě)畢業(yè)設(shè)計(jì)論文（說(shuō)明書(shū)）。 設(shè)計(jì)（研究）的重點(diǎn)與難點(diǎn)： 立柱移動(dòng)式MK7125型精密數(shù)控平面磨床砂輪架及其垂直進(jìn)給機(jī)構(gòu)和砂輪修整器設(shè)計(jì)，其中包括進(jìn)給系統(tǒng)中滾珠絲杠副及伺服電機(jī)的設(shè)計(jì)計(jì)算，進(jìn)給機(jī)構(gòu)裝配圖及相關(guān)零件圖的繪制以及其數(shù)控系統(tǒng)的設(shè)計(jì)、選用、硬件線路圖的繪制。 3、 擬采取的研究方法、步驟、技術(shù)路線 擬采用的途徑（研究手段）： 1． 收集、查閱各種文獻(xiàn)資料，初步了解數(shù)控平面磨床的整體布局及進(jìn)給系統(tǒng)，進(jìn)行精密數(shù)控磨床整體布局的設(shè)計(jì)； 2． 運(yùn)動(dòng)形式設(shè)計(jì)后，進(jìn)行砂輪架垂直進(jìn)給機(jī)構(gòu)的設(shè)計(jì)，伺服電機(jī)和滾珠絲杠副設(shè)計(jì)計(jì)算，垂直進(jìn)給機(jī)構(gòu)結(jié)構(gòu)裝配圖，繪制相關(guān)零件圖； 3． 查閱手冊(cè)，翻譯、參考英文文獻(xiàn)進(jìn)行設(shè)計(jì)計(jì)算，用Auto CAD軟件繪制進(jìn)給系統(tǒng)的裝配圖、零件圖及數(shù)控系統(tǒng)的硬件連線圖； 4． 設(shè)計(jì)中遇到的疑點(diǎn)、難點(diǎn)問(wèn)題通過(guò)廣泛查閱文獻(xiàn)資料、組內(nèi)同學(xué)相互討論及在指導(dǎo)教師的安排下在湘潭三峰數(shù)控機(jī)床有限公司進(jìn)行認(rèn)識(shí)實(shí)習(xí)，對(duì)精密數(shù)控平面磨床的結(jié)構(gòu)有進(jìn)一步的認(rèn)識(shí)。 4、 擬使用的主要設(shè)計(jì)、分析軟件及儀器設(shè)備 CAD、Pro/E、SolidWorks 5、 參考文獻(xiàn) [1] 關(guān)慧貞、馮辛安等編著.機(jī)械制造裝備設(shè)計(jì).北京:機(jī)械工業(yè)出版社,2010 [2] 李伯民,趙波主編.現(xiàn)代磨削技術(shù).北京:機(jī)械工業(yè)出版社,2003 [3] 任敬心等主編.磨削原理.北京:電子工業(yè)出版社,2011 [4] 張建民等編著. 機(jī)電一體化系統(tǒng)設(shè)計(jì).北京:高等教育出版社, 2010 [5] 易紅. 數(shù)控技術(shù). 北京: 機(jī)械工業(yè)出版社,2005 [6] 聞邦春主編.機(jī)械設(shè)計(jì)手冊(cè)（第五版）.北京:機(jī)械工業(yè)出版社,2010 [7] 姚峻.

This paper presents an alternative centerless grinding machine technology, that is, through feed surface grinder centerless grinder. In the new method, a compact centerless grinder units, guides, ultrasonic crawler, a blade of their respective holders, mounted in a surface grinder table at the workpiece is fed into and through feed centerless grinding machine operation is performed guides the space between the grinding wheel and the ultrasonic crawler. Ultrasonic crawler, the metal elastic body is bonded to the piezoelectric ceramic production, inclined at a small angle in order to provide sufficient strength to control the rotational movement of the workpiece, and feed the ultrasonic elliptical vibration of the workpiece along its axis. In this article, the movement of the workpiece control we must first ensure that the workpiece speed and feed rate can completely control the ultrasonic crawler, which is a high-precision grinding operation is essential. Then, the main process parameters, such as the eccentric angle of the workpiece, the cutting, the ultrasonic crawler inclination angle of the machining accuracy of the applied voltage amplitude (i.e., the roundness of the cylindrical workpiece and the workpiece) were clarified experiment. The results obtained show that: (1) the workpiece rotational speed can be adjusted by changing the amplitude of the applied voltage, by feedrate can be changed by applying a voltage magnitude and the ultrasonic crawler inclination angle of adjustment; (2) the top of the eccentric angle of 6 °, a larger cutting a smaller inclination angle, or the higher the applied voltage is better for higher machining accuracy; (3) and roundness of cylindrical workpiece from the initial value 16.63μm 14.86μm improvement Finally, the optimum grinding conditions under 1.49 microns and 0.74 microns. On the other hand, crawler-type centerless grinder also attracted the attention from industry and academia. designed the vacuum of hydrostatic crawler increase load capacity and stiffness of the track centerless grinding machine for high-precision applications in a plane. proposed the effectiveness of the dynamic model display hydrostatic crawler improve stability. survey tracked the basis of centerless grinder fixture mechanism system, and presents a theoretical model to predict driving grinding system the ability to resolve the fixture stable. In addition, developed a 2-D geometric model forecast track centerless grinder lobe generation and model analysis of the grinding process. From the production cost point of view, the two types of the centerless grinding machine is very suitable for the production of small species and largevolume the loading / unloading of the workpiece is very easy and fast. However, the centerless grinding machine a special-purpose machines and more expensive, it disadvantages a large variety and small batch production, in recent years, the rapid increase in demand. As a solution to this problem, the authors propose a new centerless grinding machine technology, you can perform surface grinder before. This method is based on the concept of ultrasonic crawler centerless grinding machine developed by Wu et al. (2003, 2004). Method, a compact unit based ultrasonic elliptical vibration crawler, a blade of their respective holders installed on a surface grinder table. This function ultrasonic crawler cylindrical workpiece is held in conjunction with the blade and control the workpiece speed on the end face of the elliptical motion. According to the relative movement of the workpiece grinding wheel, three types of centerless grinding operation is performed in the proposed method type: tangent feed type, feed type, and through the feed. The tangential feed type, Xu. (2010) created, taking into account the model 2-D grinding machine, in order to clarify the elastic deformation of the workpiece rounding process and process parameters workpiece roundness, simulation experiments confirm the results. Further, Wu and Xu (2010) proposed an actual increase in the material removal rate, and the final roundness maintained in the tangential feed of the high-level method. Feed type, Xu and Wu (2011) experiments confirmed its performance a simulated forecastWorkpiece rounding process. The simulation and experimental results obtained show that the eccentric angle 6 °, high machining accuracy can be obtained under a lower grinding wheel feed rate, the greater the cutting and faster workpiece rotation speed. The purpose of this document is to verify that feed type centerless grinder surface grinder. To do this, first the corresponding experimental device through the feed type centerless grinding machine is constructed by modifying the second is the existing tangent to feed type workpiece motion control tests to ensure that the speed of the workpiece and into the pass rate can completely control ultrasonic crawler, achieve high-precision grinding operations. Then grinding the actual operation carried out to clarify the effects of the main process parameters, such as the eccentric workpiece stock removal, ultrasonic crawler tilt angle and perspective applied voltage, the amplitude of the machining accuracy, i.e. the cylindrical workpiece round. 2. Surface grinder feed centerless grinding operation principles. Figure 1 illustrates the principle of operation through feed centerless grinding method and detailed experimental device construction. Establish the instrument by installing the grinding unit, composed of an ultrasonic elliptical vibration, the holders of the track, blades and holders, guide plate and the bottom plate to a surface grinder table. Grinding units, the crawler sub-structure bonding the piezoelectric device ceramic (PZT) separated the two electrodes (a and b) to the metal elastomer stainless steel (SUS 304). When both A (AC) signal phase difference (VA = the VP-PSIN (2 feet), VB = VP-PSIN (2 ft +), wherein (more than 20 kHz frequency f and VP-P) and the amplitude AC voltage) application of piezoelectric ceramics, bending and longitudinal ultrasonic vibration is very pleased to ultrasonic crawler. The synthetic vibration displacement in both directions, create an oval face metal elastomer (2005) motion. Therefore, the friction between the ultrasonic track the movement of the workpiece, the elliptical motion can be controlled through the workpiece. Constraints between the workpiece, the grinding wheel, the relative position of the blade and ultrasonic crawler wheel To determine ? eccentric angle (see Figure 1 (a)). When the ultrasonic crawler is parallel to the grinding wheel axis, i.e. gamma = 0 ° (hereinafter referred to as the tilt angle), the crawler generated by the frictional force FF between the workpiece and the ultrasonic elliptical motion in the x direction only, and is used to control the rotational movement of the workpiece, In the tangential feed type (Wu et al, 2005; Xu et al, 2010), and the feed type (2011) centerless grinder, so that the circumferential speed of the workpiece the same as the track surface of the end face of the bending vibration velocity. However, through the feed type centerless grinding the workpiece need not only rotational movement, but also through the feed motion along the z-direction, and therefore the ultrasonic crawler is, in a small angle of inclination, i.e. gamma ≠ 0 (see Figure 1 (a)), to provide adequate components FFA, friction, to control the workpiece through the feed motion. As can be seen, in traditional feed centerless grinder small taper lead size grinding wheel across a greater area of ??the wheel major stock removal shown in FIG. 1 (b), wherein the the trimming depth and HD trimming length. After the wheel, set at a given distance from the ultrasonic crawler track on the end face, the workpiece is located in the space between the grinding wheel and the ultrasonic crawler guides and Fed. Once the interference with the workpiece clockwise rotation of the actual action of the grinding wheel in the axial direction into the NW direction of the wheel speed of the workpiece in a VFA feed rate. Once the workpiece through the trimming area, the desired stock removal rate and the spark process begins, until it loses contact with the grinding wheel. In addition, the blade is wedge angle (often referred to as the blade angle) and the value of 60 degrees is generally set in the best workpiece Harrison and Pierce (2004) rounded prove.
